Introduction
As an important part of three-dimensional transportation, culverts are closely related to residents' daily travel. With the passage of time, some of the road and bridge facilities that were built earlier began to show signs of aging. Recently, a citizen reported that he witnessed a dangerous situation of cement falling on the top of a culvert, which also reminded relevant departments that it is the flood season and should pay special attention to the daily inspection and safety maintenance of urban transportation facilities......
Citizen: Witness the cement falling
Mr. Yang, a citizen who lives in Guanzhuang District, Chaoyang District, Beijing, told "Ask Beijing" (Beijing News and Broadcasting News Hotline 65159063) that there is a culvert near his home that passes through the Jingtong Expressway under Tonghuihe South Road.
Mr. Yang: This is to cross this Tonghui River there is a bridge, he is all crispy, one is against the side of this cement, I saw with my own eyes that day, it all fell, the day it fell off and almost hit people.

It is hoped that the relevant departments will eliminate hidden dangers
Mr. Yang told the "Ask Beijing" reporter that the culvert and the Jingtong Expressway were built at the same time, and it has been more than 20 years, in his opinion, the wind and sun over the years are one of the reasons for the cement on the top of the culvert to fall, and he hopes that the relevant departments will deal with the danger as soon as possible to ensure the safety of pedestrians and vehicles.
Mr. Yang: It has taken at least 20 years for Jingtong to express itself, and it has eliminated this danger and chiseled it off if it wants to fall. Sometimes when it rains, it weathers when it is sun, and it has to fall off, and it is often too dangerous.
Visit: There is a significant detachment of cement
On July 8th, the reporter of "Ask Beijing" came to the field to visit, according to the location provided by Mr. Yang, the reporter detoured to Tonghui South Road on the south side of the Tonghui River, where there are four underpass culverts, the road is relatively narrow, and there are only enough for two cars to pass through in parallel at the culvert. The reporter observed at the scene that there were traces of weathering and water erosion on the top of the four culverts, and on the top of one of the culverts, there was obvious cement falling off. According to the public notice board information at the scene, the full name of this culvert is "Tonghuihe South Road underneath the culvert on the east side of the culvert of Jingtong Expressway". Subsequently, the reporter dialed the contact number of the Tonghui River Management Office of the North Canal Management Office on the public notice board, and the staff said:
Tonghui River Management Office of the North Canal Management Office: Because this bridge is indeed not ours, we can't move the bridge. We're just in charge of the water affairs, so let's just talk about the problem of water accumulation under the bridge, waterlogging.

Reason: "Rust of steel bars" caused cement to fall
The staff who answered the phone said that they had inspected the point where there was a problem at the top of the culvert, and the specific reason was that the steel bar rust in the hanging plate on the outside of the culvert rose, but it did not affect the main body of the bridge.
Jingtong Expressway Management Branch: I went to see that one yesterday, and there was probably one of the outer hanging boards, a little bit of the concrete, a little rusty, the steel bar was rusted, and then the concrete like this cracked that one. Because the hanging plate does not belong to the appendage of the bridge, it is for the bridge to look good.

Progress: The danger has been addressed
The staff of the Jingtong Expressway Management Branch said that due to the existence of height limit poles on Tonghui Henan Road, large construction vehicles cannot enter, but they have treated the rusted part of the steel bar at the top of the culvert to remove the current safety hazards without affecting the safety of the bridge.
Jingtong Expressway Management Branch: There is a limited elevated in that block, the high car can't go, that piece can't be repaired, just temporarily knock it off first, the rust has let people pass, knock off the loose piece to it, and it won't affect the safety of this structure, it won't fall again. And then we'll probably see what we do with it later. Basically, there are no safety hazards.
