The utility model further preferably comprises a plurality of groups of grouting steel flowtube, and the grouting steel flowtube is vertically and downwards arranged from the top along the longitudinal direction of the rubble retaining wall.
The utility model further preferably adopts a reinforced concrete structure for the vertical plates, the buttress and the bottom plate.
The utility model further preferably adopts the technical scheme that the micro pile is one of reinforced concrete, steel pipes or section steel.
In a further preferred embodiment of the utility model, the anchor bars are hot rolled steel bars.
The utility model further preferably adopts the scheme that the grouting steel perforated pipe is an open-pore steel perforated pipe.
In a further preferred embodiment of the utility model, the drain pipe is a PVC pipe or a steel pipe.
Compared with the prior art, the utility model has the following beneficial technical effects:
aiming at the problem of insufficient shearing resistance of the rubble retaining wall, the utility model performs grouting in the wall body of the rubble retaining wall through the grouting steel pipe, strengthens the binding force between rubble and improves the integrity of the rubble retaining wall. Aiming at the problems of insufficient slip resistance and insufficient overturning resistance of the rubble retaining wall, the method of adopting a wall front buttress structure is adopted for reinforcement; the wall front buttress structure provides better anti-slip, anti-overturning and overall stability for the rubble retaining wall. The vertical plates are fixed with the rubble retaining wall through a plurality of groups of anchor bars, so that the wall front buttress structure and the rubble retaining wall coordinate stress. The bottom plate is fixed with the ground of the wall bottom through a plurality of groups of micro piles, so that the bearing capacity of the foundation at the bottom of the wall front buttress structure is improved, and a certain anti-slip force is provided. Aiming at the problem of water seepage of the rubble retaining wall, the reverse drainage is carried out by adopting a mode of arranging blind ditches and drainage pipes behind the wall, and the water stagnation behind the wall is effectively discharged.
The utility model has the advantages of small occupied area, convenient construction and small disturbance, has clear stress system, is stable and reliable, can comprehensively solve the common quality problem of the rubble retaining wall, and has obvious practical application value.
