严寒高地下水位地区检查井结构设计

Structural design of inspection well at severe cold and high underground water level area

针对北方严寒高地下水位地区,检查井在冬季运行期间,由于地下水的渗透,经常被冰层覆盖,无法正常运行的问题,采用焊接钢板成箱式检查井,使其密封不透水,从而有效地解决了严寒高地下水位地区检查井的冻胀及结冰病害问题。

In the severe cold northern region with high underground water level,the inspection well is usually covered by ice due to seepage of underground water.Box inspection pit made of welded steel plate is waterproof,so as to effectively solve the frost heave and freezing problem of inspection well.
