Multi-elevation deep foundation pit anchoring and pulling supporting structure

The utility model discloses a multi-elevation deep foundation pit anchoring supporting structure which comprises an anchor structure, a force transmission structure and a retaining structure. The force transmission structure is a concrete cushion layer with two-way reinforcement; the retaining structure is a reinforced concrete top beam and a supporting structure; the anchor structures are a plurality of fender posts outside a soil body failure surface; a plurality of steel bars in the concrete cushion layer of the two-way reinforcement are arranged in a single-layer two-way mode, and a plurality of steel bars orthogonal to the length direction of the crown beam are arranged according to the reinforcement ratio of 0.2%; a plurality of reinforcing steel bars parallel to the length direction of the crown beam are distributed in a phi 8-250 mode. During construction, firstly, the engineering piles and the support piles are constructed, and earthwork is excavated to the shallow elevation pit bottom; then, pile he
