no longer worry about water when the rain comes, rain can also be collected and used, this is the shadow of the sponge city. In July 22nd, Shun net visited the construction of sponge City Project in Qianfo Hill and hero hill. The scenic area is realizing the functions of mountain storage, seepage, stagnation, net, use and drainage through increasing the afforestation and backfilling, adopting the ecological pervious pavement, building the level of the level, setting up the reservoir, reforming the drainage ditch and setting the seepage pond.
paving cobblestones in natural low-lying areas to form seepage pool and storage

water channel transverse block will introduce rainwater into two sides of seepage pond
investment about 40 million yuan to make the sponge system of park scenic area
according to Anji Lei, the responsible person of Ji'nan municipal garden Bureau, city garden Bureau has started Qianfo Hill, hero mountain, tourist road, Ji Da Road and other spongy city gardens. Project construction. In the implementation of the project, the parks and scenic spots have taken measures to increase the collection and comprehensive utilization efficiency of rainwater, such as increasing the area of green space, mountain greening, compound planting, improving the rainwater collection facilities, road square ecological pavement transformation, micro terrain treatment and so on, and continuously improve the water absorption, water storage, water seepage and water purification function of the project.
up to now, a total of 15 thousand square meters of sinking green space, 23 thousand square meters of permeable paving, the masonry retaining wall, the level of 8000 cubic meters, more than 30 plants of all kinds of seedlings planted, and the construction investment of about 40 million yuan.
seepage pond, ecological permeable paving and so on to strengthen the infiltration of rain water
take Qianfo Hill scenic area as an example, according to the relevant person in charge Yang Zhenhua, first is the construction of the permeable rainwater collection water system.Amp; mdash.amp; mdash seepage pool, not only storage rain water, but also the use of natural height difference to make rain water drainage to create view water, increase At the same time, it can also meet the needs of mountain forest conservation and fire prevention.
in addition, through plant infiltration, green design and the surrounding environment of the scenic area, under the premise of retaining the original large number of cypress, select the relatively open, good light area, planting flower shrubs and ground cover, form the effect of compound planting. Improve the density of green land, reduce the scour of the surface and increase the capacity of rainwater storage.
also through the consolidation of the existing sites, increasing the undulating terrain, reducing the speed of runoff on the surface of the rainwater, playing the role of blocking the runoff, at the same time doing micro terrain finishing, reducing the slope of the plot, forming the subsidence green space, making full use of the ridge of the ridge to intercept the rain and increasing the permeability.
also use ecological permeable paving. Mountain roads and squares are paved with ecological permeable materials such as bran, sand, permeable bricks and grass paving, which fully guarantee its water permeability, strengthen the reduction and infiltration of the source of rainwater, promote the infiltration, accumulation and reuse of rainwater, which can make the road style varied and the mountain ring. The coordination of the environment reflects the ecological nature.
level, fish scale pit, water channel block surface runoff blocking surface runoff
not only such, Qianfo Hill scenic area also combines mountain features and mountain landscaping, from the upper end to the lower end layer storage, the use of natural landforms to build retaining walls, slow down rainwater velocity, increase the collection of rainwater and recycle. The slope is used to make greening along the horizontal line of the contour line of the contour line and the fish scale pit of the masonry, and to increase the retention surface and the permeability of the mountain rainwater to build the underground reservoir, and collect and utilize the rainwater runoff of the mountain and road.
the upper building of the reservoir and the sightseeing platform
according to the tourist needs of the scenic spots, the building of a recreation Pavilion and the sightseeing platform on the top of the reservoir have reached the number of water storage, rest and view. Through the end collection and lateral Road, the rainwater is introduced into the inner green space, the longitudinal road is built on the basis of the original stampede Road, and the water channel is added in the proper node, and the rainwater on the road is introduced into the water system or the green space.
the dry road at the end of the gentle road is planted in the middle, and the grass is planted in the middle, which can dissipate and block the rainwater again and promote the infiltration of rainwater.
