近几年,随着大量的高层和超高层建筑的建立,企业为提升建筑用地率,并且国家相关规范对深基坑支护工程的要求,高高层建筑地下室的设计不可避免,一些地下设施甚至有四五层,深的达十几米。所以,地下建筑开挖时的深基坑支护就成了一个必不可少的施工过程。不过因为深基坑支护为临时搭建的建筑,不在建筑核心施工的范畴内,为减少投资、降低费用及加快进度,客户、施工单位通常只注视基坑支护施工的暂时性,而忘记了基坑支护施工的复杂性、重要性及危险性,错误的认为一旦核心工程完成时,基坑支护没有垮掉就解决问题,一些施工单位甚至错误的认为挖一个大坑、随便处理一下坑壁就可以了,导致深基坑施工时安全质量故障经常发生,不单单延误了工期,还造成了非常的经济损失。
In recent years, with the establishment of a large number of high-rise and super-high-rise buildings, enterprises are inevitably required to design high-rise building basements in order to increase the rate of construction land use and the requirements of the State’s relevant specifications for deep foundation pit support projects. Some underground facilities, There are four or five layers, deep up to ten meters. Therefore, deep excavation of underground construction excavation has become an essential construction process. However, because the deep foundation pit support is temporarily constructed, it is not within the scope of the core construction of the building. In order to reduce investment, reduce costs and speed up the progress, customers and constructors usually only pay attention to the temporary construction of the foundation pit support and forget The complexity, importance and danger of the foundation pit support construction, wrongly believe that once the core project is completed, the foundation pit support does not collapse to solve the problem, some construction units even think that digging a pit, whatever Pit wall on it, resulting in the construction of deep foundation pit safety and quality failures often occur, not only delayed the construction period, but also caused a very economic loss.
