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.
Drainage well mold is to operate in accordance with the specified process, only in this way can we produce qualified shaft prefabricated parts. Of course, we should pay attention to some protection for the mold during production, but more importantly, we must use the mold according to the specified way.
Using process of drainage well mould:
1. It is necessary to use bolts to assemble the mold. The model and specification of the bolts need to be matched with the parts to be assembled. When assembling the mold, it is necessary to use an electric wrench to assemble multiple molds together, so that the bolts can firmly fix the mold. Ordinary bolt workers are more troublesome in operation. 2. Before each production, it is necessary to brush oil in the wellbore mold. Oil painting refers to painting oily materials in the mold to avoid the mud directly solidifying on the surface of the mold. 3. After pouring the mud, it is necessary to insert the vibrator into the shaft mould to vibrate the mud. After the bubbles are discharged, it can be continued to dry.
