检查井模具现浇与预制的区别是按照具体施工要求进行的，优质的钢材制作的，具有很强的硬度和能长期使用的效果，通过比较灵活的设备进行了连接，这种连接位置安装的是具有高弹性质的密封橡胶圈，这样做出来的密封性更强。
The difference between cast-in-place and prefabricated inspection well mould is made of high-quality steel according to the specific construction requirements, which has strong hardness and long-term use effect. The connection is made by relatively flexible equipment. The connection position is installed with high elastic sealing rubber ring, so the sealing is stronger检查井模具现浇与预制的区别是按照具体施工要求进行的，优质的钢材制作的，具有很强的硬假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵度和能长期使用的效果，通过比较灵活的设备进行了连接，这种连接位置安装的是具有高弹性质的密封橡胶圈，这样做出来的密封性更强。
