摘要
据工程实例 ,说明了基坑与建筑物距离过小 ,施工作业空间狭窄的基坑支护 ,采用SMW工法或SMW工法的原理 ,将高压旋喷桩和型钢结合起来 ,形成挡土和防水的复合结构 ,能够确保紧靠建筑物的安全稳定。从基坑支护方案的选择 ,技术参数的确定 ,施工过程、施工中的注意事项几方面阐述了SMW工法的应用 ,证明旋喷桩内插入型钢进行基坑支护是一种创新 ,具有很好的推广价值。
According to engineering examples, the smaller gap between foundation pit and buildings, the narrow working space of foundation pit support are explai ned. SMW working method or its principle is adopted to combine high pressure spi ral spray piles with section steel, to form the compound structure of keeping of f soil and water, to ensure the safety and stability of close buildings. The app lication of SMW working method is elaborated at some aspects of the plan select ion of foundation pit support, determination of technical parameter, constructio n process, matters needing attention etc. It proves that foundation pit support of inserting section steel into spiral spray piles is an innovation and has the good value of spreading.
