A few days ago, Some netizens left messages,
reflect Nanping Biquan Jiangyu Community, Jianyang District, Shanghai
After the completion of the flood control wall along the river, waterlogging frequently occurs,
Serious impact on life.
The reporter conducted an interview.
On April 16, affected by the severe convective weather, the Biquanjiangyu section of Binjiang West Road in Wuyi New Area was seriously waterlogged.
As early as last year, "Direct Access to Pingshan" has received feedback from the owners of Biquan Jiangyu Community on the waterlogging problem. The owners generally believe that the ponding around the community is inseparable from the new flood prevention wall of Binjiang West Road Project. In June 2023, the reporter of Southeast Network interviewed the local urban planning bureau, street, community, property and other departments on this matter. Under the linkage of multiple departments, new canals and dredging measures have been taken around the community to smoothly pass the flood season of the year. However, under the strong convection weather on April 16 this year, waterlogging occurred again around the community, and rain even flowed back into the basement of the community. After emergency treatment by the urban property management company of Wuyi New Area, the rainwater soon receded. However, the shops along the street suffered losses due to poor response, and the rainwater flooded into the shops, leaving mud in the basement of the community. Therefore, the owners of the community are worried about the safety of daily travel, and once again question the necessity of the existence of the flood wall.
After waterlogging, the construction unit will demolish and reconstruct the flood wall.
Public data shows that the construction space of Biquanjiangyu Section of Binjiang West Road cannot meet the requirements of road width due to the restrictions of the water conservancy red line and surrounding buildings. According to the preliminary design scheme, the road construction will occupy the water conservancy red line and compress the flood discharge section of Chongyangxi River. In order to solve this problem, the designer, after careful analysis and research, proposed the design scheme of "replacing the road with bridge" for the main lane viaduct and landing the auxiliary road, that is, occupying the sky and not occupying land, so as to ensure the flood discharge section of the river. The flood wall is built close to the bridge.

In this regard, the community owners do not recognize. Ms. Chen, the owner of the community, said: "The community has been built for nearly ten years, and there has never been water ingress into the basement. Since the flood wall was built, blocking the flow of water, such a dangerous thing has happened." It was reported that after the waterlogging, the owners immediately called 12345, hoping the government would deal with it, and left a message on "Direct Access to Pingshan", We hope to thoroughly solve the hidden danger of waterlogging.
Workers added underground drainage pipes for this section.
After receiving a new round of feedback from the owners, the Planning and Construction Bureau of Wuyi New Area Management Committee immediately convened the project leaders of surrounding construction sites to understand the situation and study solutions. Recently, the relevant responsible person took the initiative to contact the reporter of Southeast Net, The construction of the flood wall and the subsequent rectification scheme are described in detail.
Xu, Deputy Director of Planning and Construction Bureau of Wuyi New Area Management Committee, explained to reporters that the main reason for the waterlogging of Biquan River was the Yueliangwan area on the north side of the community (high terrain) Imperfect drainage system in early road network construction Drainage mainly depends on surface runoff. At the same time Temporary drainage channel is damaged As a result, the water on both sides converges into the community, causing waterlogging. At present, it seems that the flood control wall has indeed hindered surface runoff drainage to a certain extent, and widening and adding drainage holes are the most effective measures.
After learning from many parties, the Planning and Construction Bureau of Wuyi New Area Management Committee has taken the following measures to solve the problem: First, repair the damaged temporary drainage channel on the west side of the community, and regularly dredge and maintain the drainage channel; Second, speed up the road network construction in the west and north of the community, and improve the drainage system; The third is to add drainage holes on the flood control wall of Binjiang West Road.
In response to the owners' demand to remove the flood wall Deputy Director Xu said that the Binjiang West Road project was built according to the road network planning and design drawings. As part of the planning, the flood wall was built in strict accordance with the 50 year flood control standard. The relevant design was reviewed by the Natural Resources Bureau, the Water Resources Bureau and other parties, and supported by the corresponding monitoring data. If the flood control wall is to be removed, it will affect the acceptance of the flood control embankment project. At the same time, it needs corresponding demonstration and monitoring data to prove that the implementation period is long, which is not conducive to solving the current problems. Under the condition that the road network in the area is not perfect at present, it is more feasible to widen the drainage outlet and add drainage pipes to ensure smooth drainage of water flow in flood season. "Referring to other sections of Binjiang West Road, there will be no waterlogging when the road network is complete," said Deputy Director Xu, The flood control wall will be repaired after the road network works are completed in the later stage.
Re dredged drainage channel
On May 6, the reporter visited the Biquanjiangyu section of Binjiang West Road in Wuyi New Area again. Only the original drainage hole has been transformed into a wall cut off of about 2m and reinforced with wire mesh. According to nearby residents, the construction company has previously buried six water diversion pipes under the road surface to drain rainwater into the river. Deputy Director Xu said that in this way, the daily drainage can flow from the underground underground pipes, without affecting the landscape of West Binjiang Road, and during the flood season, sufficient drainage runoff can be guaranteed without causing ponding.

The reporter found in the interview that, Many owners are not optimistic about the measures currently taken 。 In order to prevent further losses in the flood season, the nearby stores have increased the height of the threshold built last year. As for whether the relevant measures can really work and let the residents live in peace, it needs to be verified by wind and rain. Southeast Network will continue to pay attention.
