雨水检查井模具是在城市中为常见的一种井体，因为城市多为干硬性和沥青路面，雨水排放不易，需要使用口径较大的井体来集中雨水，所以雨水检查井模具一般直径较大。在南方雨水较多的地区已经使用上了直径1500mm井体，这是为了尽可能地多排放雨水，预防发生城市内涝。生产这种大型的检查井所需要的材料也更多，少使用4mm的钢板外加6*8的勒筋才可以保证模具不会变形，并且一般长多为一面，拼装组成长井体（见下图）。The rainwater inspection well mold is the most common well body in cities. Because most cities are dry and hard and asphalt pavement, it is difficult to discharge rainwater, and a well body with large diameter needs to be used to concentrate rainwater, so the rainwater inspection wellThe diameter of the die is generally large. Wells with a diameter of 1500mm have been used in areas with more rain in the south, in order to discharge as much rain as possible and prevent urban waterlogging. What is needed to produce this large inspection well
There are also more materials. At least 4mm steel plate plus 6 * 8 rib can be used to ensure that the mold will not deform. Generally, it is mostly one side long and assembled into a long well body (see the figure below).
