Problems with construction procedures
Thread Content
May I ask that, when using urban-type roads, in the construction process, are the road drainage pipes laid immediately after the site is leveled? Will we have to dig roads again in the future? What is the right way to do it?
It is recommended to embed it in advance, but proper planning is needed – choose the right route, ensure the soil layer is not too soft, and be careful of stones and other obstacles to avoid having to redo the work
Underground drainage pipes should be pre-installed during site leveling in accordance with the city’s development plans (or cement sleeves can be used instead), but the depth at which these pipes are buried should be determined based on the soil type and in line with relevant design specifications.
The pipes in the urban area must be laid in advance, and ultrasonic testing should be carried out on the welded sections of the pipes that run across different areas; after the construction of the other pipes is completed, those pipes can then be connected to this section
The underground pipelines should be installed as soon as possible, or planned in advance. For cities as well, planning is done first, but it’s not completed all at once; after the second and third phases of planning, it’s still necessary to dig up roads. However, during the initial planning stage, care is taken to ensure that digging the ground doesn’t affect other areas as much as possible.
