Description
Technical Field
The utility model relates to a retaining wall technical field specifically is a buttress formula retaining wall.
Background
The counterfort retaining wall is a structure for supporting roadbed filling soil or hillside soil body and preventing the filling soil or the soil body from deforming and destabilizing. The existing counterfort retaining wall is composed of a wall panel, a wall toe board, a wall heel board, an inner counterfort and a bottom concrete cushion, wherein the counterfort is arranged on one side with higher relative height between a roadbed and a soil body or between two soil bodies. But the structure of the buttress-type retaining wall still has some problems:
1. the bottom concrete cushion layer is horizontally arranged, and due to different construction soil body conditions, the bottom concrete cushion layer is greatly influenced by external factors and is easy to slide.
2. When the buttress is constructed, firstly, earthwork on the position where the buttress is arranged is removed, and after the buttress is arranged, the earthwork is filled back; however, in order to stabilize the whole structure, the transverse length of the inner side buttress is large, so that the amount of earth to be removed and backfilled during construction is large, the construction period is long, and a large amount of earth can influence roads and the surrounding greening environment.
Disclosure of Invention
An object of the utility model is to solve above-mentioned problem, provide a counterfort formula retaining wall, its simple structure, firm not sliding, the earthwork volume that need clear away and backfill during the construction that can significantly reduce to shorten construction cycle.
The technical scheme of the utility model is that:
the utility model provides a buttress formula retaining wall, includes a plurality of buttresses A and the bottom concrete cushion of following length direction interval arrangement on shingle nail board, wall heel board, the shingle nail medial surface, and its technical essential is: the wall panel is along a plurality of infiltration passageways of length direction upward interval arrangement, the water inlet department equipartition of infiltration passageway has put the cobble district, and adjacent two the upper portion, the lower part of arranging in the part more than the relative low height horizontal plane between counterfort A all connect through horizontal even roof beam, arranged on the shingle lateral surface with a plurality of counterfort A corresponding counterfort B, bottom concrete cushion outside end is along horizontal plane tilt up, wall toe board and bottom concrete cushion form unsmooth complex anti-skidding key in the position department of being close to shingle central line.
Foretell buttress formula retaining wall, the vertical arrangement of shingle nail medial surface, shingle nail top width is less than the bottom width.
In the counterfort retaining wall, the upward inclination angle of the outer end of the bottom concrete cushion layer is 5-10 degrees along the horizontal plane, and the two side ends of the upper surfaces of the toe board and the heel board of the wall are inclined downwards along the horizontal plane.
Foretell buttress formula retaining wall, buttress A side is the quadrangle, buttress B side is triangle-shaped, and shingle nail height is L, and buttress A height is L1The height of the buttress B is L2，L2＜L1≤L。
The utility model has the advantages that:
1. the counterfort B is additionally arranged on the outer side face of the wall panel, so that the transverse width of the counterfort A can be reduced to the greatest extent, the amount of earth to be removed and backfilled is reduced to the greatest extent under the condition that the counterfort construction amount is basically unchanged, the construction period is properly shortened, and the design aesthetic feeling is improved.
2. Each part of the whole structure is slightly inclined, so that the whole structure is stable, the anti-sliding key is arranged on the bottom concrete cushion, the connecting beam is arranged between the counterfort A, the structural strength is improved, the counterfort type retaining wall is more stable, and the sliding phenomenon cannot occur.
3. The wall panel is provided with the water seepage holes, so that water in a soil body with higher relative height can smoothly flow out after pebbles filter silt, and the water seepage holes can not be blocked.
