某地下洞室防水技术

Waterproofing Technology for Underground Chamber

位于地下坑道尾部的某洞室按"防排结合"的原则进行了防水工程设计,其防水主体为复合式衬砌,结构为250mm厚防水混凝土加EVA防水板,排水设计为在洞室底部两侧设集水管并延至排水沟。从施工后效果来看,该设计防水效果较好。

The waterproofing design of a chamber, which is at the end of an underground tunnel, adopts the principle of combining waterproofing and drainage. The main waterproofing structure is compound liner, using 250 mm thick waterproofing concrete and EVA waterproofing board, and the catchment ducts were set at the bottom of the chamber and extended to the drainage ditch. The effect of waterproofing design is well after construction.
