During the application of the plastic inspection well in the construction site, many detailed problems were encountered. One of them is that the tolerance of plastic pipes is too serious, which leads to the need to wrap the well seat rubber ring matched with the Yidaofeng plastic inspection shaft with heat shrinkable tape. The package of heat shrinkable belt needs drying gun and canned liquefied gas. The following points are summarized about the precautions of heat shrinkable tape! 1. Usage specification

How is the indoor drainage pipe connected to the plastic inspection well? The problem of indoor drainage pipes connecting to plastic inspection wells is often encountered during site construction. The quality of the connection is directly related to the effect of water closure of plastic wells. In fact, indoor drainage pipes are generally connected to plastic inspection wells in two ways: one is on the plastic well shaft, the other is from the plastic well seat. Two situations

Before studying the difference between the two, we should first distinguish the following two concepts. The traditional inspection well refers to the inspection well stacked with bricks, which was commonly used in the past. Currently, the inspection wells commonly used in society are basically plastic inspection wells and cement inspection wells, which adopt the one-time injection molding process. Both in terms of corrosion resistance and service life, they are better than before

The connection of steel mesh skeleton plastic composite pipe adopts two types of electrothermal fusion connection and flange connection. Electric fusion connection is to insert the composite pipe seat into the electric fusion pipe fitting, so that the electric heating wire embedded in the inner surface of the pipe fitting is energized to heat it. Melting is generated by melting the inner surface of the pipe fitting, which will expand and fill the gap of the pipe fitting. Until the appearance of the pipe also produces melt, the two melts are fused together

Inspection chambers are used to inspect, clean and maintain the drainage system, and are placed where the direction or slope changes. These chambers are also called manhole chambers, and are composed of bases, risers, covers and frames. Manholes, also known as manholes, are an important part of any drainage system. These access points allow drainage professionals to inspect and measure underground utility infrastructure and perform necessary

The reason why the steel skeleton plastic composite pipe bursts is that the steel skeleton plastic composite pipe is a relatively popular new type of pipe in modern times. It has advanced technology and special materials, so the product performance is very good. In fact, good products are not enough. Our strict construction technology is also required during construction. If the technology is not up to standard, it is easy to cause pipe explosion. Then, cause explosion

Ductile iron manhole covers are generally divided into round and square ones. In terms of urban road administration, round manhole covers are generally used, because round manhole covers are not easy to tilt, which can better protect the safety of pedestrians and vehicles. The use of circle is mainly based on the fact that the length of each diameter of the round manhole cover passing through its center is the same, so if the manhole cover is rolled by the passing vehicle
