摘要
近年来,由于各种复杂原因。我国基坑工程事故常有发生,这些基坑工程事故主要表现为支护结构产生较大位移,支护结构破坏,基坑塌方及大面积滑坡,基坑周围道路开裂和塌陷,与基坑相临的地下设施变位以至于破坏,临近的建筑物开裂甚至倒塌等等。大部分基坑事故都与地下水有关,因此,在基坑工程施工中必须对地下水进行有效治理。地下水治理,主要有降水和截水两种方式。本文主要探讨一下基坑降水的现场施工的细节及现场操作。
关键词: 基坑降水井点构造降压井疏干井真空负压
Pick to
in recent years, due to the plex reasons. Our foundation pit engineering accident happens quite often, these excavation engineering accident mainly for supporting structure generate large displacement, supporting structure damage, landslide, collapse and large foundation pit excavation way around, and foundation pit craze and collapse of underground facilities in the circle of the buildings that damage, near crack even collapsed, etc. Most of the foundation pit accident are and groundwater, accordingly, in foundation pit on engineering construction of effective management to groundwater. Groundwater management, basically have precipitation and section water in two ways. This article mainly discusses the foundation pit precipitation construction site details and site operation.
Keywords: pit precipitation well point drainage well constructed step-down Wells Vacuum suction
