喷锚网技术在基坑支护中的应用

喷锚网法支护技术在基坑支护中应用具有工艺简单、施工方便、工期短、经济等优点。它广泛应用于基坑深度在5·5m以内,基坑土层为杂填土、粘土或淤泥质土的基坑支护中。但由于喷锚网法支护位移量较大,且受土质状况、地下水等影响显著,因此应根据土质状况、地下水及周边建筑等情况确定喷锚网法支护技术如何应用在深基坑支护中。

Application of Ejector anchor Retaining and Protecting for Foundation Pit

The application of ejector anchor retaining and protecting for foundat ion pit has such advantages as simple and quick construction, economic price and so on. The ejector anchor technique are applied broadly for supporting the fou n dation pit, whose soil layer consists of clay and silt, and depth is less than 5 .5m. But it is affected by the specific features such as engineering geologica l conditions and hydrological conditions, and the displacement of soil body is obv ious. So engineers should select the application range of ejector anchor retain i ng for foundation pit, according to the surrounding environment, geological and hydrological conditions.
