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

After the installation of the steel mesh skeleton plastic composite pipe is completed, a hydrostatic test is required to detect and ensure the construction quality. However, if the hydrostatic test is not standard, the accurate results cannot be detected. Next, we will learn about the correct method of hydrostatic test. 1. Before water filling, drainage shall be set at the upstream pipe top of the test pipe section of steel mesh skeleton plastic composite pipe and the convex point in the pipe section

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

At present, we can often see two kinds of manhole covers, one is the old cast iron manhole cover, the other is the ductile iron manhole cover. These two kinds of manhole covers are used in many projects. In terms of material, HT200 is used for the cast iron manhole cover, while the nodular iron manhole cover is processed with QT500-7. Generally speaking, the nodular iron manhole cover with the same weight is better than the gray iron manhole cover
