The order of rainwater and inspection wells, rainwater attached inspection wells, and the construction plan of the construction plan of rainwater dumplings! The rainwater attached inspection well and rainwater dumplings are done after the pavement project is completed? Or do it with the inspection well on the rainwater supervisor and the inspection well?

The order of rainwater supervisors and inspection wells, rainwater attached inspection wells, and rainwater dumplings are:
1, lay the rainwater main pipeline before the road base starts, and build the inspection well When the bottom cushion of the rainy well is elevated, the rain well is started. And the progress of the cushion layers of the road to adjust the height of the inspection well to the corresponding elevation:
3. Before laying the road surface layer, complete the raindous well plastering, install rainwater dumplings, install inspection well sitting and manhole cover. Coordinate with the road construction unit to ensure that after the pavement engineering is completed, rainwater dumplings can normalize the water collection function, and check the height of the well cover and coordinate with the pavement.
The expansion information:
This of rainwater pipeline construction precautions:
1, according to the layout of the overall planning, roads and buildings The principles of the shortest pipeline, the smallest burial depth, and trying to discharge as much as possible.
2, the rainwater pipe should be laid in parallel along the surroundings of the roads and buildings to minimize the cross between each other and other pipelines.
3, the pipeline should try not to know the sidewalk or grass on the outside of the road.
4, when the rainwater pipeline is laid, the horizontal distance and vertical cleaning of each other and other pipelines should be used. Determine and other factors.
5, the water flow corner should not be less than 90 degrees. When the pipe diameter is less than 300 and the water falls from the water is greater than 0.3m, the angle may not be limited.
The main inspection well needs to be done first on the road. After the road can be done outside the road, the rainwater support can be reserved during the construction of the pavement, and finally the rainwater sister -in -law can be done.
