综合管廊变形缝防水设计与施工技术

Waterproof Design and Construction of Comprehensive Utility Tunnel Deformation Joint

城市地下综合管廊作为地下构筑物,为了确保管廊安全运行,对管廊的防水要求较高,做好综合管廊防水设计与施工是重中之重。变形缝是地下综合管廊防水的薄弱环节,对整个地下管廊防水效果的影响极大,变形缝使得管廊结构之间断开,其防水完全依靠防水材料,重要性尤其突出。重点介绍了六盘水综合管廊项目防水设计及施工工艺。

As an underground structure, the waterproof requirements of urban underground comprehensive utility tunnel are important to ensure the safe operation of the utility tunnel, especially its design and construction. The deformation joint is the weak link for underground utility tunnel waterproof, and has a great influence on the overall effect of the entire underground utility tunnel waterproof. The utility tunnel structure is disconnected by deformation joint, so the waterproof relies entirely on waterproof materials. The waterproof design and construction for Liupanshui comprehensive utility tunnel are introduced in detail.
