层间水丰富情况下基坑防水施工技术研究与应用

RESEARCH AND APPLICATION OF FOUNDATION PIT WATERPROOFING CONSTRUCTION TECHNOLOGY UNDER THE CONDITION OF RICH INTERLAYER WATER

中国工艺美术馆工程基础底板施工时,雨季刚刚结束,地表水因重力因素逐渐向下渗透。随着土层的变化,土壤的含水率和渗水率也发生相应改变,基坑开挖后使得层间水异常丰富。本项施工技术解决了中国工艺美术馆工程在层间水丰富情况下基坑防水施工的技术难题,保证了基础底板的正常施工和工期安排,同时保证了工程质量和安全。

When foundation slabs of the China National Arts and Crafts Museum(CTCM)were constructed,the rainy season had just ended,and the surface water gradually infiltrated downward due to gravity.The water content and permeability rate of soil vary along with the change of soil layers,and the excavation of foundation pits enriches the interlayer water vastly.In this paper,relying on the research on this construction technology,technical problems in the foundation pit waterproofing construction of CTCM under the condition of rich interlayer water have been addressed,which not only ensures the normal implementation and schedule of foundation slab construction,but guarantees the quality and safety of the project.
