1、 How to solve the problem that HDPE plastic inspection shaft needs to be heightened? HDPE double wall corrugated pipe is adopted, and each corrugated pipe has a flaring, which can directly socket the shaft to increase the height. Other solid wall pipes are added with shaft joints.
2、 How many holes can be drilled at most? Sewage manhole price | 1000 plastic manhole | 600 plastic manhole Zhenglin Building Materials When the incoming outgoing pipe diameter is less than or equal to 110, the shaft can be drilled with 3 holes, and when the diameter is greater than or equal to 160, three holes can be drilled on different planes.
3、 Where are rubber rings mainly used? The flexible connecting parts at the connection socket between the shaft and the shaft seat or between the shaft seat and the pipeline are used for sealing, waterproofing, settlement resistance and tensile resistance of the inspection well. They are important parts for the perfect connection of various parts of the plastic inspection well, and are usually made of rubber.
4、 How to select rubber ring? Since the outer diameters of pipes from different manufacturers are different, different pipe outer diameters are sealed and calibrated with rubber rings of different thicknesses. 5、 Is it easy to block in the practical application of HDPE plastic manhole? The inner wall of the plastic inspection well seat is smooth and smooth, and the drainage performance is excellent, which changes the node of the advanced plastic pipe existing in the traditional brick well. The rainwater and sewage discharge efficiency is more than three times that of the traditional well, and the blockage is greatly reduced.

6、 Can you run down the well? The plastic manhole does not need to be lowered into the well to change and subvert the traditional brick well habit, so the internationally advanced cleaning concept is adopted to implement mechanical cleaning.
7、 Do you need concrete for the foundation of plastic manhole? No, the concrete construction does not meet the requirements of plastic inspection wells for uniform settlement of soil; When the buried pipeline is subject to settlement, the inspection well cannot be subject to corresponding settlement, which will lead to damage of the well seat due to inconsistent force.
8、 What are the requirements for installing HDPE plastic manhole foundation? Answer: The inspection well should be installed on the dense foundation soil layer, or on the treated dense foundation after the well pit is excavated. The foundation of the inspection well generally adopts the sand gravel cushion foundation. There are five functions of plastic inspection wells: land saving, energy saving, water saving, material saving and environmental protection.
