The mould for cement inspection well is divided into three parts: reserved hole, adjusting ring and necking. The bottom of the well body is a reserved hole, which is used to connect those places that need future repair and maintenance, and is also prone to failure. The middle part is the adjusting ring, which is used to adjust the underground high speed of the whole well body to adapt to various installation environments, which can effectively reduce the cost and improve the efficiency. The top is the closing part, which is the place connected with the ground. The manhole cover with the same diameter as the closing is installed on it, so that a complete set of inspection wells are installed.
The operation steps of the cement inspection well mold are according to the common shape of the mold. In terms of the manufacturer's production, the inspection well mold is usually very characteristic, with holes on both sides, and the thickness of the steel plate used in the initial stage of the production of the inspection well changes with the size of the mold. No matter prefabricated inspection well canal or cast-in-place inspection well, orders are placed according to the steel plate requirements provided by customers. The inspection well mould is composed of two parts, external mould and internal mould. Mold size can be customized according to the requirements. The steel external form uses two thick and uniform panels and high-strength reinforced plates, which are welded by professional electric welding machine. The external form has good stability and is very firm. It is not easy to deform and crack when pouring concrete in the later stage, and has a long service life. Demoulding is more convenient and fast. The internal mold is composed of three steel plates, one smaller and two larger, which is convenient for demoulding. Because inspection wells are in great demand in some special projects, they can be processed according to the drawings provided. Pay attention to the details and reserve holes in advance for mass production.
