Construction method for deep foundation pit penetrating underground permeable layer
The invention discloses a construction method for a deep foundation pit penetrating an underground permeable layer, relates to the technical field of foundation pit excavation, and provides the construction method for the deep foundation pit penetrating the underground permeable layer, and accordingly, the foundation fit earth excavation process, the building foundation construction process and the foundation pit earth backfilling process can be prevented from being affected by underground water. The method comprises the steps that a soil body above the permeable layer is excavated; a water collecting well is excavated; water in the water collecting well is pumped through a suction water pump; concrete is sprayed to a slope hanging net of an upper pit to protect the wall; an open drain and a spray drain are excavated; a soil outlet lane is excavated; the foundation pit is excavated; solid construction is carried out in the foundation pit; and soil backfilling is carried out. The construction method is suitable for construction of various deep foundation pits penetrating the underground permeable layer. The structure is simple, operation is convenient, and environment friendliness and energy saving are achieved. The effect of stopping of surface water above the permeable layer and the water stop effect on the underground water below the permeable layer are good.
