Road network construction in Wuhan area, pre-embedding construction of supporting roads for water supply and drainage pipes

The construction of the road network in Wuhan area is advancing steadily. As the core link of the construction of the underground pipe network, the pre-embedding construction of the supporting road for water supply and drainage pipes is directly related to the long-term operation of the water supply and drainage system of the road network. In the early stage, it is necessary to combine the hydrological characteristics of the area with dense rivers and lakes and high groundwater level to complete accurate on-site surveys, and select suitable plastic pipes to ensure that they have excellent pressure resistance, corrosion resistance and settlement resistance. During construction, trenches are dug in strict accordance with the specifications, and the flatness of the bottom of the groove and the drainage slope are controlled to avoid pipe damage due to water accumulation or uneven force. Pipe interfaces need to be precisely aligned during the laying process, and connections that meet process standards are adopted to ensure tight sealing. When the pipe trenches are backfilled, they are layered and tamped, taking into account the load-bearing requirements of the road surface and the protection In view of the concentrated climate characteristics of Wuhan during the flood season, temporary diversion facilities should be set up synchronously during the construction process to prevent water accumulation in the trench from affecting the work progress and construction quality. After completion, the closed water test and settlement monitoring will be carried out section by section to investigate the hidden dangers of leakage, confirm the stability of the pipe force, and build a strong underground water supply and drainage protection line for the safe operation of the road network in the area.
