Foundation pit waterproof curtain and construction method thereof

YAN QUANDE

The invention relates to the field of constructional engineering, and discloses a foundation pit waterproof curtain and a construction method thereof. The foundation pit waterproof curtain comprises a plurality of water stop columns, wherein the plurality of water stop columns are engaged with one another, reinforcement cages I are pre-buried in the water stop columns, one end of the reinforcement cages I extend to the positions above the top surfaces of the water stop columns, connecting beams are poured among the tops of the plurality of water stop columns, reinforcement cages II are pre-buried in the connecting beams, a plurality of bundles of steel bar groups are inserted into the reinforcement cages II, one end of each steel bar group penetrates through the connecting beams and are located on the side, away from a foundation pit, of the waterproof curtain, and the other end of each steel bar group is located in the foundation pit. The foundation pit waterproof curtain has the effect of reducing deformation of the waterproof curtain caused by side pressure so as to increase the stability of the waterproof curtain.
