Sewage well mold is a kind of inspection well mold, the whole is composed of three parts: reserved hole, adjusting ring and closing. Reserved holes are used to connect underground places that are prone to failure and need regular maintenance, such as underground pipe joints, elbows, cables, etc. The middle part is the regulating ring, which, as the name implies, is used to adjust the height of the whole well in the underground, which can meet the requirements of various installation depths and effectively reduce the installation cost. The top part of the whole well body is the closing part, which is flush with the ground. Finally, a manhole cover with the same diameter as the closing in diameter is added, so that the whole buried inspection well is flush with the ground.
At present, there is no single specified size of the sewage well mold. Because of the different regions and construction schemes, the inspection wells used will be different. Generally, the inspection well molds are customized according to the needs of customers. At present, the inner diameter of the inspection well mold with the largest size is 80 cm and the inner diameter is 1 m. Inspection well mold belongs to a kind of heavy-duty mold, and the volume of prefabricated parts of inspection well is relatively large, so there is no plastic for inspection well mold at present, and the cost of FRP mold is relatively high. Therefore, the inspection well mold is generally made of steel mold, and the sewage inspection well mold materials are all made of high-quality plate as the main material, and the additional plate reinforcement is used to fix the main board The service life of the die is effectively improved.
