密集井点小泵量基坑降水技术的应用

Application of Foundation Pit Dewatering by Small Pumping Amount in Multiple Well Points

摘要:

介绍了在水源补给充分、水位降深较大的基坑施工中，采用密集井点小泵量连续抽水控制地下水位，使降水漏斗曲面平缓，减小基坑周围地面沉降的风险的方法，以及取得的良好的降水效果。

Abstract:

The paper introduced the groundwater level control by continuous small pumping amount in multiple well points for the foundation pit construction with full water recharge and large drawdown, which made the curved surface of dewatering funnel flat, reduced the land subsidence around the foundation pit and obtained good dewatering result.
