井點降水施工實踐探索
隨著高層建筑的不斷增加，在舊城區施工采用井點降水，引起鄰近建筑、管線、路面開裂下沉的現象屢見不鮮。因此，采用井點降水要特別慎重并采取相應對策。我們認為，井點降水，一是要在挖至設計基底標高時不出現流砂，保證基坑內正常施工作業；二是要防止基坑外的地下水位下降對周圍已建建筑物、管線、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
