摘要
为保证深基坑支护的施工安全和承载力,文章以高明区更合镇合水水厂储水坝建设工程为例,研究高压旋喷桩施工技术在深基坑支护中的应用效果.结合深基坑支护设计方案及土层勘查结果,确定高压旋喷桩施工工艺流程,并选择合理的施工设备,完成施工参数设定后,按照施工标准完成高压旋喷桩施工.分析施工结果可知:该施工技术应用后,深基坑支护地基的最大沉降值为30.5 mm,满足工程标准.
Abstract
In order to ensure the construction safety and bearing capacity of deep foundation pit support,this paper studies the application effect of high pressure rotary jet pile construction technology in deep foundation pit support by taking the water storage dam construction engineering of Heshui water plant in Genghe Town,Gaoming District as an example.Combined with the deep foundation pit support design scheme and the soil layer investigation re-sults,the construction process of high pressure rotary jet pile is determined,and reasonable construction equipment is selected.After the construction parameters are set,the construction of high pressure rotary jet pile is completed according to the construction standards.The analysis of the construction results shows that after the application of the construction technology,the maximum settlement value of the deep foundation pit support foundation is 30.5 mm,which meets the engineering standard.
