文章从防水原材料进场质量控制入手,严控隧道开挖、初期支护质量,细化纵向排水管及土工布、防水板施工工艺,加强施工过程工序质量控制,采用材料防水与构造防水相结合,柔性防水材料与接缝密封材料互补并用的多道防水措施,达到了预期的一级防水的标准,为隧道的防排水设计与施工提供了有益的参考。
This article starts with the quality control of waterproofing raw materials, strictly controls the quality of tunnel excavation and initial support, and details the construction process of longitudinal drainage pipes, geotextiles and waterproof plates, and strengthens the quality control during the construction process. It adopts the combination of material waterproofing and structural waterproofing , Flexible waterproof material and seam sealing material complement each other and use a number of waterproof measures to achieve the expected level of waterproofing standards for the drainage of the tunnel design and construction provides a useful reference.
