Waterproof curtain wall for foundation pit
The invention discloses a waterproof curtain wall for a foundation pit, and belongs to the field of construction of foundation pits. At least one layer of waterproof curtains consisting of a plurality of high-pressure jet grouting piles is arranged on outer sides of support piles of the foundation pit or among the support piles of the foundation pit; bottoms of the high-pressure jet grouting piles are placed on an impervious stratum below the bottom of the foundation pit; the adjacent high-pressure jet grouting piles of the waterproof curtains on the same layer are gripped with one another; the adjacent high-pressure jet grouting piles between the waterproof curtains of the adjacent layers are gripped with one another; the waterproof curtains arranged among the piles are gripped with the support piles; and the diameter of a gripping portion of each high-pressure jet grouting pile is 1/4-1/3 of the diameter of each pile. The waterproof curtain wall for the foundation pit has high permeability coefficient in underground water, has a high gripping effect when difficulty on tube well dewatering is high, is convenient and speedy, and has a high waterproof effect.
