| 预制混凝土检查井按其井室形状可分为圆形和矩形，按材料性能可分为普通预制混凝土检查井和耐腐蚀预制混凝土检查井。其与管道的连接方式可采用刚性接口，也可采用柔性胶圈接口。预制混凝土检查井井壁踏步、井壁开孔或预留管口的尺寸、位置和数量以及吊检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 环或吊装孔位置可由设计确定。预制混凝土检查井可依据检查井各部件的尺寸、重量和具体生产方式采用单件制作或部分部件整体制作。 Prefabricated concrete inspection wells can be divided into circular and rectangular according to their chamber shape. According to material properties, they can be divided into ordinary prefabricated concrete inspection wells and corrosion-resistant prefabricated concrete inspection wells. It can be connected with pipeline by rigid interface or flexible apron interface. The size, location and number of prefabricated concrete inspection wellbore steps, wellbore openings or reserved pipe openings, and the location of hoisting rings or hoisting holes can be determined by design. Prefabricated concrete inspection wells can be manufactured by single piece or parts as a whole according to the size, weight and specific production mode of each component of the inspection wells |
