Pit-in-pit underground water treatment method for water-rich pebble stratum
The invention discloses a water-rich pebble stratum pit-in-pit underground water treatment method, and relates to the technical field of dewatering construction, and the method comprises the following steps: S1, occlusive piles are poured at the peripheries of a foundation raft sump and an elevator shaft pit to form a waterproof curtain, and a water suction pump position is reserved in the waterproof curtain; s2, a reinforced concrete water pressing plate is poured in a pit formed by the secant piles; s3, a water collecting pit and a slope side wall water pressing plate of the elevator shaft pit are installed and erected; s4, waterproof cloth is laid, a water suction pump is placed at the reserved position of the water suction pump, and graded broken stone is filled; and S5, finishing the construction of the cushion layer. The treatment method is simple in process, secant pile construction is conducted through each foundation pit, the problems that due to the fact that geology is uneven, a pit in a water-rich pebble stratum pit is not formed in excavation, collapses and the like can be solved, and the problems that the well point dewatering effect is poor, and construction cannot be conducted through a steel plate caisson method can also be solved. Disturbance to the foundation is reduced to the maximum extent, the influence on adjacent foundation pit supporting is reduced, and the requirement for pit-in-pit construction of the water-rich pebble stratum can be met.
本发明公开了一种富水卵石地层坑中坑地下水处理方法，涉及降水施工技术领域，包括：S1：在基础筏板集水坑、电梯井坑的周边灌注咬合桩，形成止水帷幕，在止水帷幕内预留抽水泵位置；S2：在咬合桩形成的坑内浇筑钢筋混凝土压水板；S3：安装支设集水坑、电梯井坑的斜面侧壁压水板；S4：铺设防雨布，并在预留的抽水泵位置放置抽水泵，填充级配碎石；S5：完成垫层施工。本处理方法工艺简单，通过每个基坑进行咬合桩施工，能够解决因地质不均匀导致的富水卵石地层坑中坑开挖不成形、塌陷等问题，还可以解决井点降水效果差、钢板沉箱法无法施工的问题。最大限度的减少对地基扰动，减少对临近基坑支护的影响，能够满足富水卵石地层坑中坑施工要求。
