The design of rectangular well mold is based on the prefabricated concrete rectangular inspection well mold, and the rectangular inspection well mold, as well as sewage, rainwater and other inspection well templates, constitutes this category. In the production of drainage well mould, it is very important for mould making. The mold detail drawing of rectangular inspection well is a strict practical standard, but in different mold specifications, the production mode and production technology of the mold are the same. Although the formwork of drainage well needs complex process in production, the formwork after production can be used for a long time of 5 years, so the production cost of formwork can be ignored. So if we consider long-term investment in the production of prefabricated drainage wells, we only need to consider the cost of concrete and labor.
The first aspect of rectangular well demoulding is to pay attention to. Before the production of inspection well mould, a layer of engine oil is coated on the inner wall of mould, which is a quick method of demoulding. There is also the storage problem of inspection well mould. The inspection well mould also has life. After use, the inspection well mould is stored in a cool, ventilated warehouse without chemical substances, which is a value Problems to be noted, through these precautions, it is no problem that the service life of the inspection well mould is rarely used for more than 5 years, and it can be used for a longer time if it is well maintained. The good service life of the inspection well mould will also achieve the ideal effect. At the same time of meeting the domestic market, we should develop the international market more. Many developed countries are increasing the demand of our country's mold equipment year by year, so the potential is great. The embedded reinforcement of the rectangular well mould is just at the joint of the two formworks. When installing the formworks, the reinforcement shall be wrapped with Shanghai cotton strip to prevent leakage of slurry.
