Yield composite bamboo rib anchoring and shotcreting supporting foundation pit and construction method thereof

The invention discloses a yield composite bamboo rib anchoring and shotcreting supporting foundation pit and a construction method thereof. The yield composite bamboo rib anchoring and shotcreting supporting foundation pit comprises a foundation pit, a bamboo rib anchor rod, a yield device and a bamboo filament spraying concrete layer with bamboo filaments mixed. The bamboo rib anchor rod is embedded in a setting-out hole in the side wall of the foundation pit. One end of the yield device is connected with the bamboo rib anchor rod, and the other end of the yield device stretches out of the side wall of the foundation pit and is fixed. The bamboo filament spraying concrete layer is laid on the side wall of the foundation pit, and the end portion of the yield device is embedded in the side wall of the foundation pit. The yield composite bamboo rib anchoring and shotcreting supporting foundation pit and the construction method thereof have the beneficial effects that the yield device can conduct segmented step-
