as the four major ecological civilization construction of open exhibition water in our city One of the system, the implementation of the water system connected engineering is a key work to build a healthy and beautiful water ecosystem, and is also an important Continuation Project of the East Route of the South-North Water Diversion Project. At present, the connecting project of Tianshan irrigation area and jigin trunk channel has begun to supply water to the urban area. The project of Yuqing Lake diversion project is completed in the end of September this year. The water diversion project of Yufu River's supine Hushan Reservoir is currently being transferred, and the construction will be started in May 1st. It is also in the planning design.
six major connected projects are the necessary conditions for the water diversion from south to North in our city. It is also the key project to optimize the allocation of water resources and build a modern water network system in our city. This is not only an important part of urban development, but also an important measure to improve the quality of the city image, improve the living conditions of the residents, and get along with the nature in harmony. It is an effective way to realize the urban resource saving, environment friendly and social sustainable development. After the complete completion of the
project, the city will realize the joint dispatch of the Yellow River water, the Yangtze River water and the surface water. The annual maximum water transfer is 300 million cubic meters. It will bring abundant water to the southern mountain and the urban area, supplement the water of the rivers and lakes, realize the continuous flow of the main rivers in the four seasons, and improve the ecological landscape of the river water and create green. The coloured corridor landscape belt achieves the general goal of "spring, lake, river, water and Jing Mei". The connecting project of
Tianshan irrigation area and Ji Ping trunk canal will improve the connecting project of the urban ecological environment field mountain irrigation area and the Jinping trunk canal. It is the first part of the Ji'nan water network, which is the first connected and connected project to the urban water supply in the city. The project was started in November 11, 2012, with a total investment of 6 million 560 thousand yuan. At present, the main project has been completed and passed through acceptance. And it began to supply water to Ji'nan city in April 5th.
not long ago, the reporter found that the turbid the Yellow River water was pumped into the sinking sand pool in the first grade pumping station in the first grade pumping station in Tianshan irrigation district. After the sedimentation of 2 sank basins with a total length of about 8 kilometers and more than 2700 mu of land area, the the Yellow River water was injected into the dry canal through the connection project of Tianshan irrigation area and Ji Ping trunk canal, and injected near the sluice gate. Xiaoqing River. This project can make the Tianshan irrigation area change from Ji'nan strategic water source to replenishing water conservation spring and creating water ecological civilization city. In the non water diversion period of South to North Water Diversion, the engineering camera uses the jiging canal for the Yuqing lake water reservoir and the Xiaoqing River Ji'nan section to replenishing water and his water supply, in order to reduce the North store of Yuqing lake water store. The operation load of the sub sand tank is increased, and the guarantee rate of water supply and the water quality of the water supply are increased. The water supplement for the Xiaoqing River can improve the water quality of the Xiaoqing River, improve the ecological environment of Ji'nan City, make full use of the comprehensive benefits of the Jinping trunk canal, and realize the optimal allocation of water resources. It is reported that the first grade pumping station in Tianshan irrigation area is in the vertex of the the Yellow River bend, and the water extraction conditions are superior. There are rock submersible weirs in front of the pump station. It has the function of blocking sand, and the sediment concentration of water is low, which is 1/4 of the normal the Yellow River water content.
1 million cubic meters of water transport capacity of Tian Shan irrigation area and jigin trunk canal connected project daily can be realized through jiging canal to Yu Qinghu, Xiaoqing River and yuhushan reservoir. Shi Liwen, Secretary of the Party committee of the electric irrigation management department of Tianshan, Pingyin, Ji'nan, told reporters that Tianshan irrigation area, using its own advantages, realized water replenishment to Ji'nan city through connecting the project, and became an important part of the Ji'nan water network. The irrigation water in Tian Shan has also realized the living, industrial and agricultural production of urban residents, industrial and agricultural production and ecological supplement from a single agricultural irrigation water. The transformation of source and other multi-purpose water supply plays an increasingly important role in the water conservancy and social and economic development of the city.
Yuqing Lake diversion project allows the citizens to drink the Changjiang River Yuqing lake reservoir, one of the most important water supply reservoirs in our city, with an average daily water supply of about 400 thousand cubic meters, accounting for 40% of the city's water supply. The water source of Yuqing lake reservoir is the Yellow River water, which is taken from the Yellow River Pumping Station of the North Dian Zi. The Yellow River water needs sediment treatment before entering the reservoir. However, at present, the North basin has exceeded the design life and the siltation is very serious. Therefore, Yuqing lake reservoir needs to develop new source of water supply. In December 15, 2012, the construction of the Yuqing water diversion project was formally started. The project was taken from the new five branch water sluice of the Jisun trunk canal. Through a new 1.037 km water diversion culvert and a reservoir pumping station, the water was brought into the Yuqing lake reservoir. The design flow was 9 cubic meters per second, and the investment was 41 million 250 thousand yuan. The implementation of
Yu Qing Lake water diversion project can not only further optimize the supply of water resources in the city, alleviate the shortage of water resources, but also play an important role in protecting the spring water and improving the ecological environment. After the completion of the project, the Yuqing lake water reservoir can not only use the the Yellow River water of Tianshan Mountain, but also the Changjiang water transferred from the north to the north, and bring the Changjiang water from the south to the north into the city pipe network, thus entering the home of the people of our city.
the project has been progressing smoothly. It has completed the construction of water stop curtain in the pumping station, pouring pile, excavation, concrete pouring of the wall of the passage layer, concrete pouring on both sides of the front pond, the support of the floor plate of the water pump floor and the concrete pouring of the floor of the fire pool, which has excavated 700 meters of the dark culvert base slot and the dark culvert body. 48 sections of concrete are poured in 432 meters. The project has completed 85 thousand cubic meters of earth excavation and 3900 cubic meters of concrete. The whole project is planned to be completed by the end of September this year. When the East Route Project of the south to North Water Diversion Project is completed, it will give full play to its benefits simultaneously.
the water diversion project of the Yangtze River water and the Yellow River water is one of the key construction projects to create a water ecological civilization city in our city. The high speed railway enters the Yufu River, then flows along the Yufu River to the Hushan Reservoir. The design flow of the project is 3.5 cubic meters per second, the daily water supply capacity is 300 thousand tons, the whole project is about 30 kilometers long, of which 13 kilometers in Changqing District, 13.3 kilometers in the middle area of the city, 3.3 kilometers in the city district, and the total investment of 370 million yuan. The main content of the construction is to lay up nearly 30 kilometers of water conveyance pipeline with a diameter of 1.6 meters, and build Jia Zhuang, Luo Er Zhuang, Zhai and the first three pumping stations.
because of the low south and low East height of Ji'nan, the Yellow River water and Yangtze River water are introduced into the reservoir from the three stage pump station through the Jinping channel. The water elevation difference is 100 meters, the total lift reaches 178 meters, the pipeline diameter is large and the distance of water transportation is long, the difficulty can be imagined. In order to ensure operation on time in May 1st, a project mobilization meeting was held last week. The meeting was required to complete the full completion of the work before the end of April. The Municipal Engineering Command signed the responsibility with the central, the calendar and Changqing districts, completed the pipeline paving in mid July, and realized the subsection of water before the end of December.
Yufu river reservoir water transfer project is the key project of constructing the modern water network in our city. The water and Yangtze River water is transferred into the reservoir to realize the joint dispatching of the surface water, the the Yellow River water and the Yangtze River water, which will bring a rich water source to the southern mountain area and the urban area, supplement the water of the river and lake, and realize the main river. The flow of the four seasons is flowing.
make full use of the characteristics of the groundwater in the city of Yufu River to supplement the urban groundwater, and recharge the source in the dry period. It can fundamentally solve the problem that has been plaguing the city, ensuring the continuous sprays of the spring group. A number of outlets will be set up along the line, which will be used to supplement the source and landscape water of Yufu River, and connect with the water conveyance main canal of the hushushan reservoir, and directly supply water to the waterworks.
in addition to the water diversion project of yuufu mountain reservoir in yuuhe River, the diversion project of Yuqing lake and the water diversion project of yuufu Hushan Reservoir, the city is now designing and planning the North store water transmission line, the Jinxiu Chuan reservoir water transmission line and the wolf cat landscape reservoir transmission line, in which the North store water transmission line uses its yellow river diversion gate. Water to Yuqing lake water sink sink sand pool, new sluice gate to La Shan flood channel water pipeline, using the La mountain flood channel to the central city of La Shan River, Xingji River and other watercourses, not only can do urban landscape, but also in flood season, non flood season, ecological water supply, the design of water capacity of 100 thousand tons a day.
"big water network" supports the development of water resources in Ji'nan. It is one of the cities with serious shortage of water resources. With the expansion of urban scale, the promotion of rural urbanization and the improvement of the people's living standards, the water resources are becoming more and more scarce. The average water resources in Ji'nan are about 1 billion 748 million cubic meters for many years, of which only 1 billion 156 million cubic meters are available, and the per capita water possession is less than 1/7 of the country's per capita share. The shortage of water resources has become the main "bottleneck" affecting the economic and social development, and the water shortage, water shortage and water quality lack water are the main factors affecting the economic and social development. With the coexistence of the problems of water shortage in management, the contradiction between the life of the drought years, the production water and the ecological water and the spring water spurt are particularly prominent, and face the double pressure of water supply and water conservation. In this case, our city adheres to the policy of sustainable development, based on the reality of Ji'nan, in order to ensure the safety of urban and rural flood control, the safety of water supply, the safety of water environment and the normal gushing of the spring group, and build the "large water network" across the North and south, across the East and the west, and cover the whole area. Go into development.
6 Dalian Tong project in our city is an important part of creating a water ecological civilization city. It is also the key project to optimize the allocation of water resources and build a modern water network system in our city. The main task is to use water source and new source of water through water diversion, water transport, storage, water supply and other projects, to supplement the urban residents' living and industrial water supply in the water shortage area, and to give consideration to the purpose of ecological water use. Based on existing flood control and disaster reduction, urban and rural water supply and water system ecological backbone system, large rivers, backbone tributaries and water transport channels are the main frames, backbone reservoirs, lakes and wetlands are the nodes, and the backbone water network system is constructed. Through perfecting the supporting project, forming a regional cascade water network, making full use of the comprehensive functions of the main structure of water network in flood control, water supply and water ecology, and coordinating the "five water", such as the local surface water and groundwater, the water of the Yellow River, the water of the Yangtze River and the unconventional water, so as to achieve the "three nets linkage", and achieve the optimal allocation of water resources. The purpose of efficient use. Taking the basin area as the unit, the river channel as the transport carrier, the reservoir and the lake as the storage center, the construction of the connected engineering and the control hub project, the perfect supporting project, the water network engineering system which is interconnected, mutually regulated and complementary in accordance with the requirements of the introduction, storage, discharge and regulation. To give full play to the comprehensive benefits of water conservancy projects has injected a strong impetus to the realization of leaping development of water conservancy.
provides an important part of urban development for the establishment of water ecological civilization city, which is an important part of urban development. It is an important measure to improve the quality of the city image, improve the living conditions of the residents, and get along with the nature in harmony. It is to realize the resource-saving, environmental friendly and social sustainable development of the city. The effective way of the exhibition. The six major connected projects implemented in our city are aimed at the realization of the water conservancy modernization with the characteristics of the spring city, the development of urban and rural water conservancy, the overall arrangement of life, production and ecological water, and the strengthening of the basic function, resource function and guarantee function of the water conservancy, which will play a very important supporting role in the development of our city's economic and social development. The water security, which will accelerate the reform and development of water conservancy, is not only related to the safety of flood control, water supply and food security, but also to economic security, ecological security and national security.
at present, our city has entered the key period of the construction of the water ecological civilization city. After the implementation of the water system ecological water network, it provides a guarantee for the ecological water demand and water safety in Ji'nan. At the same time, the water surface area of rivers and lakes in Ji'nan has been increased, which greatly alleviated the benefit of urban heat island, created conditions for the restoration of waterfront ecosystem, and laid a solid foundation for the benign development of urban ecology. With the increase of the landscape water and the volume of water storage, the construction and reconstruction of the ecological river bed and the revetment, the groundwater has also increased the stable supply source, and the problem of the groundwater funnel can be solved. The water quality problems faced by the ecological water system are effectively dealt with by the pollution control, the pollution cutting, the water collection and the water saving, the rain pollution control and the water supply, which lays the foundation for the benign cycle of the ecosystem.
the joint operation of Yangtze River water, the Yellow River water, surface water, ground water and unconventional water will bring abundant water to the southern mountain area and the urban area, supplement the water of the river and lake, realize the continuous flow of the main rivers in the four seasons, so as to improve the waterscape of the river, create a new scenic spot for leisure and entertainment, and build a green corridor landscape belt. Now it is the general goal of "spring, lake, river, water and Jing Mei".
