The inspection well is a subsidiary structure for the drainage pipe of the rain water. It is a necessary facility to check and dredge the pipe regularly and prevent the pipeline from clogging.
传统砖砌检查井的施工方法是用砖块砌筑井体，然后将管道插入井体并用水泥砂浆填补井管接口处。该工艺落后，施工效率低，连接效果差会导致严重渗漏、泄漏，并违背了标准化原则。
The construction method of the traditional brick masonry inspection well is to use the brick masonry well, then insert the pipe into the well body and fill the pipe interface with cement mortar. The process is backward, the construction efficiency is low, the poor connection effect can lead to serious leakage and leakage, and it violates the standardization principle.
