at Ji'nan times / > in Lin toe Lane A well cover can be called.Amp; lsquo covers strong.Amp; rsquo, it is said that it was installed in the 30s of last century, and it is still very hard now. On the 6 day, there was a public report to the newspaper.
6, the reporter came to Lin Di lane near the Communist Youth League road. In front of gate 12 of Lin Di lane, there is a well lid which has been covered with thin layer of bitumen, which is what the people refer to as Getejo. The city's civil hammer gently cracked an asphalt and revealed the true face of the manhole cover. The reporter saw that the head of the well was raised in the middle, with a hole on it, rusty and spotted, but it looked very hard. The reporter tried to lift the lid of the well with a hook and could not carry a vehicle. Around the manhole covers, a circle of steel rings tightly surrounds the manhole covers. Mr. Ma, a nearby resident, said the well cover was the original old Telecommunications Bureau. In the first two years, the Telecommunications Bureau repaired a line and opened the manhole cover. Mr. Ma said.
in order to find out the property rights unit of the well cover, the reporter inquired into the mobile, Unicom and Telecom, and finally learned that the manhole cover was Unicom. Zhang Zidong, deputy director of Ji'nan Unicom's Department of transportation and maintenance, said that the communication pipeline, including this part of the well cover, was not built in the 30s of the last century, but was built in the late nineteenth Century. It is the only one hundred year history communication pipeline existing in Ji'nan, which is built by the Japanese. Zhang Zidong said that this well cover is commonly known as the Wang Ba well cover, because it looks like a middle bulge, like Wang Bagai, is cast iron. It is characterized by the fact that the car has been milled without any movement, and it will not be damaged or damaged for a long time. Like many manholes cover up now, they will bang, but it will not. The reason is the quality. There is a ring around the cover of the well, which is tightly combined. The quality of the cement is very good. When the pipe was dismantled in June last year, it was very difficult to destroy the cement with the sledge hammer, and the pipes were made of ceramics. Zhang Zidong said.
