摘要
随着地下空间开发和高层建筑的发展,深基坑施工与日俱增。大部分深基坑工程处于城市中密集的高层建筑群内,不仅施工场地狭小,工程基础与周边建筑物基础紧密相连,基坑开挖过程容易造成周边地下水渗漏,引发周围土体变形,引起周围建筑物的沉降,严重的影响地下工程的施工质量、施工效率、施工环境、施工安全。针对以上问题,本文结合实际工程案例,提出一种新型的基坑止水方式—全套管咬合砂浆止水桩基坑止水技术,并对全套管咬合砂浆止水桩性能、施工工艺及实际工程应用效果进行研究,以供类型工程借鉴。
With the development of high - rise buildings and the underground space exploitatio, Most of the deep foun- dation pit engineering located at intensive high -rise buildings in the city. Not only the foundation of the engineering closely linked to the surrounding buildings foundation , but also excavation process easy to cause the surrounding groundwater seepage, deformation of surrounding soils, cause settlement of surrounding buildings, seriously affected the construction quality of underground engineering, the construction efficiency, construction environment, the con- struction safety. , the paper combined with the practical engineering examples, Put forward a new way of foundation pit water stop - full casing bite slun＇y pile foundation pit water technology, water stop and check on the casing bite mortar water performance of pile, construction technology and practical application effect, to provide reference for the type of project. To solve above problems.
