With the popularity of the concept of sponge city, the construction of sewers has also become a hot spot. Taking the Pearl Bay Area of Guangzhou sponge city as an example, rainwater and sewage can be separated by separating rainwater and sewage. Domestic sewage is transported to the sewage treatment plant through pipelines and used for greening irrigation, vehicle washing Road flushing, toilet flushing, etc. Among them, rainwater inspection wells and sewage inspection wells are needed. What are the advantages of plastic inspection wells?

1、 Strong sealing

After the reconstruction project of rainwater and sewage diversion, the number of plastic inspection wells for drainage in Chengdu alone is more than 35000, and the number of plastic inspection wells for drainage in China is at least 15 million. If the sealing is not good, a large amount of water resources will be lost, and the sewage will seep into the groundwater and cause secondary pollution. The plastic inspection well is made of high-density polyethylene through one-time rotational molding process. The plastic material itself has good sealing performance, and the connection with the drainage pipeline is flexible. The rubber ring and heat shrinkable sleeve are used to connect, which can ensure the sealing at the connection of the pipeline.

2、 High drainage efficiency, not easy to block

The drainage efficiency of the plastic drainage manhole is 2~3 times that of the traditional brick masonry. Because the inner wall of the plastic manhole is smooth and smooth, and there are diversion grooves, the dirt is not easy to stay, reducing the possibility of blockage, so the manpower cost is saved in all aspects of later maintenance

3、 Long service life

Plastic inspection wells are made of polyethylene PE, polypropylene PP, polyvinyl chloride PVC. These plastics have a service life of more than 50 years under the use conditions of various strong acids and alkalis, considering weathering factors. It can ensure that the local drainage system can be used for decades, greatly reducing the maintenance cost.

It can be seen that in all aspects, plastic inspection wells are very important water-saving and environmental protection facilities. At present, it is widely used in urban waterlogging drainage, sewer and other pipeline construction. In the summer storm season, it can avoid rainwater infiltration and sewage cross flow, causing groundwater pollution.
