Summary:A construction method for the supporting system of foundation pit and its side slopes includes such steps as driving thick steel bars into earth layer of side slopes by pneumatic hammer to form anchor piles, spreading the mash reinforcement over the side slopes of foundation pit, reliably connecting the mash reinforcement to anchor piles, and spraying concrete to form protecting slopes. Its advantages are simple construction, reliable anchor, low cost, and less disturbance to the earth layer of side slope.
