Description

Wall front buttress structure for reinforcing rubble retaining wall

Technical Field

The utility model relates to the technical field of rubble retaining wall reinforcement, in particular to a wall front buttress structure for reinforcing a rubble retaining wall.

Background

The rubble retaining wall is widely used once because of its low cost, convenient local materials, fast construction speed, but when it is used for about 15 years, many problems occur successively, such as: the wall body is externally bulged, the mortar joints are weathered, stones fall off, water seepage and the like, and a plurality of potential safety hazards are brought to the surrounding environment. Thus, many rubble retaining walls are in need of repair and reinforcement treatment every year throughout the country due to the annual repair loss.

For the rubble retaining wall with a certain service life, the conventional reinforcement treatment scheme is generally a anchor rod and lattice reinforcement scheme, an anchor rod reinforcement scheme, a grouting reinforcement scheme, a wall thickness increasing scheme and the like. The above schemes have limitations on the conditions of use thereof, for example: the anchor rod reinforcement generally needs sufficient working space, and the rubble retaining wall to be reinforced should be capable of bearing the vibration influence during the anchor rod construction; the scheme for increasing the thickness of the wall body should have enough occupied space to accommodate the newly added retaining wall.

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.
