Construction method for foundation pit dewatering sedimentation prevention
According to the technical scheme, the construction method for foundation pit dewatering sedimentation prevention is characterized in that the construction method for foundation pit dewatering sedimentation prevention comprises the following construction steps that a plurality of dewatering wells arranged at intervals are arranged in a foundation pit area, and the unwatering area of the dewatering wells covers the area of a foundation pit; the depth and the distribution position of the precipitation well are combined with a three-dimensional seepage model to perform precipitation simulation, and the underground water level heights inside and outside the foundation pit area after precipitation and precipitation prediction results of the distribution positions of underground water at different water level heights are obtained; a plurality of recharge wells and observation wells which are arranged at intervals are arranged outside the foundation pit area according to the rainfall prediction result; water is injected into the recharge well and underground water in the dewatering well is discharged synchronously; according to the scheme, the recharge wells can be arranged outside the foundation pit in a precise positioning mode, recharge is conducted corresponding to different underground water levels, and the overall recharge effect in the area range is improved through mutual cooperation of the different recharge wells.
本发明提供一种基坑降水防沉降的施工方法,其技术方案要点是基坑降水防沉降的施工方法,包括以下施工步骤:在基坑区域内布置若干个间隔排布的降水井,若干个降水井的疏干面积覆盖基坑面积;降水井的深度和分布位置结合三维渗流模型进行降水模拟,获得降水后的基坑区域内外的地下水位高度,以及不同水位高度的地下水的分布位置的降水预测结果;根据降水预测结果在基坑区域外布置若干个间隔排布的回灌井以及观测井;往回灌井内注水与排出降水井内的地下水同步进行;本方案可实现回灌井采用精准定位的方式布置在基坑外,对应不同地下水位分别进行回灌,并通过不同回灌井相互配合提升区域范围内的整体回灌效果。
