某大型盛水构筑物基坑降水问题的分析与处理
发布时间：2019-06-15 13:41
【摘要】：盛水构筑物由于自身的特点,对于施工过程中的地下水水位变化较为敏感,降水不到位容易引起盛水构筑物上浮。结合某净水厂大型盛水构筑物在基坑降水过程中出现的问题,通过对现场实际情况的勘察与分析,根据场地各土层渗透系数调整基坑降水方式。工程实践表明,该工程所采用的轻型井点方式降水取得良好的工程与经济效果。
[Abstract]:Due to its own characteristics, the water structure is sensitive to the change of groundwater level in the construction process, and the lack of precipitation can easily cause the structure to float. Combined with the problems of large water structure in the process of foundation pit dewatering in a water purification plant, through the investigation and analysis of the actual situation on the spot, the dewatering mode of foundation pit is adjusted according to the permeability coefficient of each soil layer of the site. The engineering practice shows that the light well point precipitation adopted in the project has achieved good engineering and economic results.
