The production process of the mould for the egg shaped groove of the road culvert needs to be transported to the processing plant for prefabrication, and the raw materials such as cement, sａnd and gravel should also be transported to the factory for mixing. Most of the concrete specifications we use are relatively good, and its strength is very good. Concrete materials are mixed according to a certain proportion, so that it can be fully mixed together, and the use of the role in the project is also better. In the use of road gutter oval groove mold, Japanese Style Oval sump mold prefabrication production, if the concrete has occurred condensation, it can not be used. After the production of concrete blocks, the prefabricated blocks should be transported to the construction site, and then transported to the designated location for installation. The placement should be stable, and the mortar between the blocks should be full enough to bond tightly together. The overall gap should be small. After the production is completed, the mould of Japanese ovate water collecting tank should be stored in the warehouse, and the warehouse should be managed by special personnel. The main purpose is to regularly monitor the temperature and humidity in the warehouse, and the space inside should be large enough, and the mold should be maintained regularly to protect the quality of steel mold The next prefabrication effect of Japanese ovate collecting trough mold will not be affected
