The “Prefabricated Polyester Resin Concrete Drainage Inspection Well” has been approved by the China Municipal Engineering Association for the issuance of the “2023 Second Batch of China Municipal Engineering Association Group Standard Formulation (Revision) Plan” (Zhongshi Xie [2023] No. 92). The main editing units are Guangzhou Municipal Group Co., Ltd. and Kedeli New Materials (Guangdong) Co., Ltd..

The implementation of green and low-carbon concepts in various aspects of urban infrastructure construction, operation, and management, the construction of low-carbon smart cities, and the change of the extensive construction method of “massive construction, massive consumption, and massive emissions” in the field of urban and rural construction have become a key force in the development of the industry. In recent years, the government has implemented a series of policies to actively promote new processes, materials, and equipment, promote the industrialization of new construction, support the development of prefabricated buildings, promote the application of prefabricated component products, and improve the prefabrication rate. These policies will undoubtedly provide a broad market for various types of prefabricated assembled concrete components..

Inspection wells are important supporting components in underground pipelines. Prefabricated assembly methods have advantages over concrete lining methods, such as high strength, tight joints, no leakage, and fast construction and installation. In developed countries such as Europe, the United States, and Japan, more than 90% of inspection wells are prefabricated in factories and assembled on site. Polyester resin concrete is a technically reliable high-strength material with advantages such as corrosion resistance, wear resistance, high strength, good hydraulic performance, long service life, and high cost-effectiveness for long-term use. When used in the production of prefabricated inspection wells, it is an advanced green building material with a fast production process. Compared with ordinary concrete, it has the advantages of corrosion resistance and stable quality. Currently, it is widely used in municipal highway construction both domestically and internationally It is widely used in agricultural water conservancy construction, power and urban comprehensive pipe gallery construction..

According to the construction of municipal drainage networks in recent years, the average annual growth of municipal drainage networks in urban areas (including counties, townships, and administrative towns) throughout the country during the 13th Five Year Plan period is 72000 kilometers. A large number of inspection wells have been built, and the production of inspection well components has been industrialized and standardized into a series of products. This is the trend for the development of inspection wells in the future, with broad application prospects. Polyester resin concrete inspection wells can be used in various scenarios such as municipal rainwater, sewage drainage pipeline inspection wells, highway drainage pipeline inspection wells, water conservancy drainage pipeline inspection wells, industrial area drainage pipeline inspection wells, etc. In addition to standard circular and rectangular shapes, they can also be specially shaped for different purposes and applications such as drainage pump stations, distribution wells, inverted siphon wells, monitoring wells, maintenance wells, etc. However, currently there are no production standards or related inspection standards in China, and the development of this standard is necessary and has great application prospects..
