Supporting structure of foundation pit

The utility model relates to a supporting structure of a foundation pit. The method is suitable for the technical field of foundation pit supporting. According to the technical scheme, the supporting structure of the foundation pit is characterized in that a plurality of row piles anchored into the ground are arranged on the ground around the foundation pit, the tops of the row piles are connected through a top beam, and a plurality of pipe piles anchored into the ground around the foundation pit in the inclined direction are further arranged on the top beam. A waterproof curtain is arranged on the side, away from the foundation pit, of the tubular beam. Therefore, the row piles anchored into the ground play a role in enhancing the structural strength of the ground around the foundation pit, the row piles are connected through the top beams arranged at the tops of the row piles, the connecting strength between the row piles is improved, and then the structural strength of the ground around the foundation pit
