Most of the steel molds for inspection wells are prefabricated. The precast concrete blocks are put into use again. During the rainy season, we should take corresponding measures to prevent the shaft from floating. The length of the shaft should be designed according to the specific use environment. When it is difficult to give certain data, the length needs to be reserved to avoid too short. Appropriate concrete will make the quality of the inspection well better. We will choose the type of concrete according to the different environment. Some kinds of concrete with high strength, hardness and strong persistence are welcomed by the market, especially some concrete have good acid-base resistance. The concrete inspection well made in this way can work better in the underground pipeline system. More inspection wells have been made by the steel mould of inspection well. When placing the inspection well, we should keep the verticality of the shaft and ensure the accuracy of its position.
