建筑工程中的深基坑支护施工技术

Deep Foundation Pit Support Construction Technology in Construction Engineering

伴随我国城市化进程不断加快,高层建筑的数量越来越多,为保证高层建筑的稳固性,需要通过深基坑施工来保证工程质量,由于深基坑开挖的深度较深,并且我国很多地区的地质条件较差,若未能采取有效的支护施工技术措施,将会存在安全隐患和质量问题,因此,需要通过深基坑支护施工技术使工程施工得以有效完成。目前,常用的深基坑支护施工技术主要包括土钉墙支护、锚杆支护、地下连续墙支护以及钻孔灌注桩支护等施工技术,但每一种支护施工技术具有不同的特点和适用范围,在实际应用时,还必须结合工程实际情况合理选用支护施工技术,从而提升深基坑支护施工技术的实施效果。本文首先对深基坑支护施工技术进行概述,然后以实际工程为例,对该工程深基坑支护施工技术的实际应用进行探究,从而为类似工程的有效开展提供支持。

With the continuous acceleration of urbanization in China,the number of high-rise buildings is increasing.In order to ensure the stability of high-rise buildings,it is necessary to ensure the quality of the project through deep foundation pit construction.The geological conditions in many areas of China are poor.If effective technical measures for supporting construction are not taken,there will be potential safety hazards and quality problems.Therefore,it is necessary to use deep foundation pit supporting construction technology to effectively complete the project construction.At present,the commonly used deep foundation pit support construction technologies mainly include soil nailing wall support,bolt support,underground diaphragm wall support and bored pile support,etc.,but each support construction technology has different characteristics and scope of application.In practical application,the support construction technology must be reasonably selected according to the actual situation of the project,so as to improve the implementation effect of the deep foundation pit support construction technology.This paper firstly summarizes the construction technology of deep foundation pit support,and then takes the actual project as an example to explore the practical application of the deep foundation pit support construction technology in this project,so as to provide support for the effective development of similar projects.
