在人防工程及地下构筑物建设中,常常会遇到开挖后的基坑挡土问题。挡土技术到目前为止,有很多种方法,如放坡、钢板桩、锚喷等等,各种方法都有利有弊。在现实中,特别是在市区中心地段,施工场地非常狭小,不能有太大的噪音,且必须确保基坑稳定、保证正常施工,又不影响周边建筑物,能选择的方法就很有限了。现在我们特别向大家推荐“SMW”工法。
In civil air defense projects and construction of underground structures, excavation often encountered after the excavation retaining the problem. Retaining technology So far, there are many ways, such as grading, sheet pile, anchor spray, etc., all kinds of methods have pros and cons. In reality, especially in the downtown area, the construction site is very small, can not have too much noise, and must ensure the stability of the foundation pit to ensure normal construction, without affecting the surrounding buildings, the method of choice is very limited . Now we recommend “SMW” workmanship to everyone.
