最近几年以来,我国建造出越来越多的高层以及超高层建筑物,为了有效提升建筑用地率,为了满足我国对人防工程以及基础埋置深度所提出的相关要求,开发商纷纷对高层以及超高层建筑做出了地下室设计。为了建造地下室,必须要在工程开始之前开展挖掘工作,因此在施工过程中地下建筑开挖时候的深基坑支护设计就变得尤为重要,其关系到建筑的安全性与稳固性。目前,土钉墙支护施工技术被广泛地应用在深基坑工程施工当中,此项技术能够加固土体,保证施工的稳定性与安全性,是深基坑施工中的一项重要技术。本文主要介绍了钉墙支护技术的工作原理与优势,分析了其在建筑深基坑施工当中的具体应用,以供参考。
In recent years, more and more high-rise and super high-rise buildings have been built in our country. In order to effectively raise the rate of construction land, in order to meet the relevant requirements of China on the civil air defense projects and the depth of foundation embedding, Super high-rise building made basement design. In order to build a basement, excavation work must be carried out before the start of the project. Therefore, the design of deep foundation pit support for excavation of underground structures during construction has become particularly important, which is related to the safety and stability of the building. At present, soil nailing wall support construction technology is widely used in deep foundation pit construction, this technology can reinforce the soil, to ensure the stability and safety of the construction, is an important technology in deep foundation pit construction. This article mainly introduces the working principle and advantages of nail wall support technology, analyzes its concrete application in the construction of deep foundation pit construction for reference.
