Drainage well mold is actually only a kind of inspection well mold. Drainage well mold is generally divided into square well mold and circular well mold, which can better serve the cement inspection well components required by municipal engineering. In the production of inspection well, this kind of integral type is widely used at present. It has a special inner cavity shape. When the cement is formed under pressure, it becomes the shape of inspection well we want. Because in this process, the mold needs to bear the pressure of concrete and the effect of external force, so the material needs to have strong hardness and stiffness, and the precision and scale should be designed according to the drawings. The development of inspection well level has become the focus of the development of our mold industry To mark one.
The reason why steel formwork is used in drainage well mould is that steel formwork has great advantages. When welding, it can also bear relative stress, and the vibration platform can maintain no deformation under high-speed operation. In this process, we should always check its use effect. Inspection well steel mold uses good quality concrete as prefabricated products, so when using concrete, we should pay attention to some conditions. First of all, the concrete can not be placed in high temperature environment. High temperature conditions will make the concrete lose its original hardness and stiffness, which is difficult to use again. Before construction, we should go through strict inspection, and after the completion of the concrete products, we should also pay attention to some conditions Second, some wet concrete can not be put into the production because it has too much moisture, which will cause the phenomenon of caking and losing the use effect. These concrete should be put after screening. Thirdly, we should mix and mix before using, and can not be stored in cold conditions, otherwise it will give way The concrete quality is seriously damaged due to the water expansion on the surface.
