Further setting the following steps: the bearing wall that retaining wall contacted with high slope soil layer is the arcwall face setting of indent.
Through adopting above-mentioned technical scheme, the arcwall face of indent will increase the contact surface street of soil layer and retaining wall and then realize making the pressure that receives on the retaining wall reduce, and then effectively improve the compressive capacity of retaining wall.
Further setting the following steps: the side of the retaining wall far away from the high slope soil layer is vertically provided with a reinforced wall, the reinforced wall is superposed with the vertical symmetrical surface of the bearing wall of the retaining wall, and the bottom surface of the reinforced wall is vertically provided with reinforcing steel bars embedded in the soil layer.
Through adopting above-mentioned technical scheme, with the help of the reinforcing bar that reinforced wall and reinforced wall bottom surface bury in the soil horizon make the retaining wall of indent still have higher intensity in its thinnest department to make retaining wall stability can ensure.
Further setting the following steps: the outer wall of the bottom of the cantilever part is provided with a base plate for resisting toppling on the surface of a soil layer.
Through adopting above-mentioned technical scheme, improve the anti ability of empting of friction pile with the help of the base plate, make overall structure more stable.
Further setting the following steps: the ratio of the length of the fixing part to the length of the cantilever part is 1: 3-1: 4.
through adopting above-mentioned technical scheme, guarantee to bury intraformational fixed part of soil and have the ability of will strong anti empting to whole friction pile, guarantee overall structure's stability.
To sum up, the utility model discloses a beneficial technological effect does: the integral structure has stronger stability through the combination of the anti-slide piles and the retaining wall, and is simple in design and convenient to install and easy to implement.
