老式砖砌式排水检查井因材质不耐酸碱性，长期使用受腐蚀后，造成井体的渗漏严重。新式的混凝土模块式排水检查井利用模块的嵌锁性，防水效果好，有效改善在砖砌检查井闭水时出现爬梯、管道与检查井衔接处漏水及因渗漏导致路面沉降等情况。
The old brick drainage inspection wells are not acid and alkali resistant because of their poor material. After long-term use, they are corroded, resulting in serious leakage of the wellbore. The new type of concrete modular drainage inspection well has good waterproofing effect, which can effectively improve the situation of climbing stairs, water leakage at the junction of pipeline and inspection well and pavement settlement caused by leakage.
同时，新型排水检查井整体结构受力明确，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。该工艺的运用为湖州首次，下步也将推广到全市市政道路雨污井的建设中。
At the same time, the overall structure of the new drainage inspection well has clear force, easy to build, simple and convenient, and is suitable for outdoor rainwater and non-corrosive sewage pipelines in municipal, industrial and civil buildings. The application of this technology is the first time in Huzhou, and the next step will be extended to the construction of rain and sewage wells on municipal roads in the city.
