探究复杂环境下建筑基坑支护施工技术

Study on the Construction Technology of the Foundation Pit Support in the Complex Environment

随着城市化建设的不断推进以及科技的进步发展,使得现代建筑项目不断增加,施工环境也越来越复杂,施工难度逐渐的增加,作为现代建筑施工项目中的重点工作之一,基坑工程对于建筑在整体质量有着非常重要的作用。因此面对复杂的地质环境,需要严格地按照施工组织设计开展基坑支护施工,对于各项施工工序严格地进行控制来充分确保基坑支护施工的整体效果。龙岩师范附属小学三期工程施工环境复杂,应用到的基坑支护技术众多,该文主要分析了基坑监测,探讨了双管高压旋喷桩形成桩间土支护及止水帷幕、引孔并插埋安装钢管施工。

With the continuous progress of urbanization and the development of science and technology,the modern construction projects are increasing,the construction environment is becoming more and more complex,and the construction difficulty is gradually increasing.As one of the key tasks in modern construction projects,foundation pit engineering plays a very important role in the overall quality of buildings.Therefore,in the face of complex geological environment,it is necessary to carry out foundation pit support construction strictly according to the construction organization design,and strictly control each construction procedure to fully ensure the overall effect of foundation pit support construction.The construction environment of the third phase project of Longyan Teachers College affiliated Primary School is complex,and there are many foundation pit supporting technologies applied.In this paper,the monitoring of foundation pit was analyzed,and the construction of soil support and water stop curtain between piles formed by double pipe high pressure rotary jet grouting pile was discussed.
