管井和轻型真空井点组合 在某电厂深基坑降水中的应用

以某电厂翻车机室为研究对象, 针对其深基坑降水降深大, 工期紧等特点, 主要介绍了该工程的工程地质及水 文地质条件, 并且运用管井和轻型真空井点组合降水的方法, 设计了基坑降水处理的施工方案, 确定了降水的各个 参数。实践证明, 管井和轻型真空井点组合应用效果良好, 有效保证了工程的顺利进行, 加快了工程进度, 缩短了工 期。结合实例提出了降水过程中应注意的问题及应对措施。

Tube and light vacuum well point combination in the deep foundation pit precipitation in a power plant

Dumper chamber in a power plant as the research object, in view of the deep foundation pit precipitation drawdown is big, the tight etc, mainly introduced the project of engineering geological and hydrogeological conditions, and using the method of tube well and lig ht combination of vacuum well point precipitation, design the construction scheme of foundation pit precipitation process, determine the various parameters of precipitation. Practice proves that the tube well and lig ht vacuum well point combination application effect is good, effectively ensure the smooth progress of the project, to speed up the construction schedule and shortening the time limit for a project. Finally, this paper expounds the prob2 lems should be paid attention to in the process of precipitation and the countermeasures.
