Shandong Primary Molding Plastic Inspection Well Supply/Hebei Plastic Finished Well Company

Precautions for construction of plastic manhole:

1. Consider Plastic pipe The axial bearing capacity of. Because the menstrual pain of the plastic inspection well is the plastic buried underground The Conduit After being placed, it should be buried with soil, and then it will be affected by http://www.sdpegj.com/ Axial compression will be caused due to the influence of the traction force of backfill.

2. The protective cover shall be specially designed. Because the material properties of plastic inspection wells will directly determine the pressure bearing capacity of plastic inspection wells. Generally, the materials of plastic inspection wells are poor, so the pressure bearing capacity of corresponding plastic inspection wells will be weak. Manhole cover Bearing capacity shall be considered in design.

3. Seasonal frozen x15hde soil. To solve the problem of seasonally frozen soil, we can refer to the Code for Design of Building Foundation in Frozen Soil Areas.

4. The plastic inspection well knows several friction coefficients. In the calculation parameters of backfill downward traction, several friction coefficients should be known. Not only the friction coefficient between the concrete pile and the soil, but also the backfill soil http://www.zbpeg.com/ The friction coefficient with the plastic wellbore should also be clarified.
