Rainwater Pipeline Network (Phase I) Construction Project in Duerbote County, Daqing City, Heilongjiang Province. This project is located in Duerbote County, Daqing City, Heilongjiang Province, and is funded and constructed by the Urban Management and Comprehensive Law Enforcement Bureau of Duerbote Mongol Autonomous County. (1) Construct a urban rainwater drainage channel starting from the Chengnan New Area and extending to Qijia Pao; the total length of the new rainwater pipelines is 11,040.85 meters. Of this, 8,097.85 meters consist of rebuilt gravity-fed rainwater pipelines, with pipe diameters ranging from d600 to d2000. The pipes used are reinforced concrete pipes. (The route: The new rainwater pipelines start along Nan Yi Er Road, with a length of 6,199.85 meters) ； Starting from Chengxi Diandian, the main rainwater drainage pipeline is laid out to Jiangjiawei Zi Pao; the length of the newly constructed pipeline is 1,898 meters ； A new gravity-fed rainwater connection pipe has been installed, with a length of 900 meters and a diameter of d300; the pipe material is ductile iron ； The newly constructed pressure outlet rainwater pipeline for the Wenxi Nuoniupao-Qijiaopao rainwater pumping station is 2,043 meters long, with a diameter of DN1800; the pipe material used is welded steel pipe ； (2) Build 1 gate with dimensions B×H=2.4 meters×2.2 meters at Dianpao; build 1 gate with dimensions B×H=4.0 meters×2.2 meters at Jiangjiawei Zipo; renovate 1 gate with dimensions B×H=2.4 meters×2.2 meters that connects Jiangjiawei Zipo and Woniu Zipo ； (3) Renovate 518 meters of the Woniubao drainage channel, dimensions: B×H=12 meters×4 meters ； (4) 2 new rainwater drainage pump stations will be constructed, namely: 1 pump station with a capacity of 1.5 cubic meters per second in the South City New Area, and 1 pump station with a capacity of 5 cubic meters per second in Woniupao ； (5) Dredged 10,824 cubic meters. The project investment amount is 69.65 million yuan.
