随着高层建筑的不断增加，在旧城区施工采用井点降水，引起邻近建筑、管线、路面开裂下沉的现象屡见不鲜。因此，采用井点降水要特别慎重并采取相应对策。我们认为，井点降水，一是要在挖至设计基底标高时不出现流砂，保证基坑内正常施工作业；二是要防止基坑外的地下水位下降对周围已建建筑物、管线、道路路
Dewatering Practice
With the increasing high-rise buildings, the construction used in the old city well point dewatering, causing neighboring buildings, pipelines, road subsidence cracking occurrences. Therefore, the use of dewatering should be particularly careful and take corresponding measures. We believe that, well point dewatering, it is necessary to dig to the design in the basement level does not appear when the flow of sand to ensure the foundation of normal construction operations; second is to prevent the decline of groundwater level outside the excavation has been built on the surrounding buildings, pipelines, roads, road
