Concrete inspection well steel mold is a professional steel forming tool specially used for prefabricating or cast-in-place concrete inspection wells. Made of Q235B steel plate through cutting, bending, welding and reinforcement, it is detachable and reusable, mainly used to produce well bodies, well shafts and necking components of inspection wells for underground pipe network projects such as municipal administration, communities, factories and mines. It is widely applied in drainage, sewage, rainwater, power, communication and fire-fighting inspection wells, replacing traditional bricklaying to realize standardized, industrialized and efficient production. With high strength, high forming precision, convenient demoulding and customizable specifications (round, square/rectangular, diameter and height can be customized according to drawings), it can be reused hundreds of times, greatly improving construction efficiency and quality stability, and is an essential core tool for modern underground pipe network construction.
