[Gansu Jinchang] Do a good job of collecting and using the rainwater and not allowing the rainwater to solve the problem of waterlogging in the urban area

At about 6 pm on July 10, there was a strong water drop in Jinchang City. The largest hour rainfall that night reached 30 mm, and the rainfall of Jinchuan District alone was as high as 16.8 mm, which was the largest hourly rainfall in recent years. Careful citizens found that every time in the urban section of the city in the urban area the next day in previous years, there will be different degrees of stagnant water, but this year is rare.

In this regard, the reporter visited the Municipal Engineering Management Office of Jinchuan District. Yu Haiyan, the person in charge of the rainwater pipeline construction project of Tianjin Road to Beihuan Road, told reporters that in recent years, in order to solve the urban waterlogging and fully collect and use rainwater, the Jinchuan District Municipal Engineering Management Office has successively organized and implemented the water roads. Recharge projects, rainwater collection and reconstruction and urban rainwater collection and utilization project. On the sections of the five green separation bands of Xinhua Road, Yan'an Road, Nanchang Road, Shanghai Road, and Jinchuan Road in the urban area, more than 3,000 pieces are replaced with the fedstone of the leak hole road; 5 light lanes on the west side of Shanghai Road The water road section was buried in rainwater collection and emission pipelines 134 meters, and 11 sets of rain wells were set up; 3376 meters were built on Changchun Road (Kunming Road to Beihuan Road), Kunming Road (Tianjin Road to Changchun Road); The northwest corner of the northwestern corner of the intersection, the northwest corner of Tai'an Road and the Guangzhou Road, the northwest corner of the Cross of Guilin Road and the northwestern corner of Guilin Road are built. The new rainwater collection tube was built at an intersection of 800 meters, focusing on solving the serious accumulation of water in Changchun Road, Tai'an Road, and Kunming Road.

The Municipal Engineering Management Office of Jinchuan District also makes an article from the upstream of the rainwater gathering, and the collection of rainwater is collected into the Xiganqu and nearby green belts, which effectively reduces the water accumulation of water sections such as Nanchang Road, Shanghai Road, and Yongchang Road, especially the water section of the water sections, especially the water, especially the water, especially the water section of the water sections, especially the water, especially the water, especially the water section of the water section of the water section, especially the water. Construction of 3 rainwater collection ports on the west side of Yongchang Road (Qingyang intersection), and two rainwater collection ports were built on the park road bridge and Jinchuan Road and bridge, so that the mining area of ​​Jinchuan Group and Jinchuan Road flowed to Yongchang Road. Dry canal solves the problem of severe water accumulation in this section. At the same time, the local road surface of Xinhua Road and the Southwest Cross of Xinhua Road and Shanghai Road solved the problem of serious water accumulation after the rain. In response to the serious problems of rainy water on the cross on Tai'an Road and Guangzhou Road, the rainwater was drained into the nearby green belt by adding a temporary pump to accelerate the discharge of rainwater.

This year, combined with the urban renewal action to make up the shortcoming PPP project, Jinchuan District raised a funds of 17.48 million yuan for the rainwater pipeline construction project for Tianjin Road to Beihuan Road. — Tianjin Road), Tianjin Road (Nanchang Road -Beihuan Road) laid 7,665 meters of rainwater collection pipe network, and set up rainwater and rain inspection wells at various intersections and along the line; , Effectively solve the problem of water collection and emissions after the rain. At present, the Tianjin Road Lauret Rainwater Collection Pipe Network has been basically completed, and the construction of Nanchang Road and Shanghai Road Rainwater Pipeline will be completed in August to October.

In the next step, the Jinchuan District Municipal Engineering Management Office will actively prepare for the implementation of the municipal regional drainage pipe network reconstruction project. The total budget investment will be more than 31.31 million yuan, mainly to remove the original drainage pipes such as the park road, Yan'an Road, Changchun Road and other sections and replace it with it to replace it with it with it with it to replace it with it with it to replace it with it with it with it to replace it with it with it. The concrete pipelines of the larger pipe diameter have 251 stones in synchronous reconstruction. The project is planned to start in October 2022, and it is completed in December 2023. "The successive implementation of these projects will effectively alleviate the problem of urban waterlogging during heavy rainfall or continuous rainfall." Yu Haiyan said.
