建筑施工中深基坑施工技术应用分析

Application Analysis of Deep Foundation Pit Construction Technology in Construction

深基坑支护施工直接关系着施工环境基础结构的稳定性,决定了施工项目的安全状态。常用的深基坑支护技术主要包括旋喷桩支护喷射注浆法、钻孔灌注桩支护法和内支撑梁支护法3种。对上述3种深基坑支护技术的特点与主要适用条件进行了研究,并通过具体案例对深基坑支护技术的实践应用进行了探索。

The supporting construction of deep foundation pits is directly related to the stability of the basic structure of the construction environment and determines the safety status of the construction project.Commonly used deep foundation pit support technologies include rotary grouting pile support jet grouting method,bored pile support method and internal support beam support method.In this paper,the characteristics and main applicable conditions of the three deep foundation pit support technologies are studied,and the practical application of deep foundation pit support technology is explored through specific cases.
