The concrete modular drainage inspection well consists concrete shaft wall module, masonry mortar, filling and core concrete, coating, jointing, pulp, wipe and triangle ash concrete. The stress of its overall structure is clear, the masonry of the inspection wells with different structural sections and sizes is easy, simple and convenient. It is suitable for the outdoor rain of municipal, industrial and civil buildings and the non-corrosiveness sewage pipeline engineering. On the basis of engineering practice, this paper sums up the construction technology of concrete modular drainage inspection wells.%混凝土模块式排水检查井由混凝土井壁墙体模块、砌筑砂浆、灌芯混凝土、包封混凝土、勾缝、座浆、抹三角灰组成，整体结构受力明确，对于不同结构断面和尺寸的检查井易于砌筑，简单便捷，适用于市政、工业与民用建筑室外雨水及无腐蚀性污水管道工程。本文在工程实践的基础上，总结出混凝土模块式排水检查井施工工艺。
