Abstract
The utility model discloses a balance weight type retaining wall. The balance weight type retaining wall comprises a wall base and a wall body fixed to the upper side of the wall base and used for supporting a hillside soil body. The back of the wall body is provided with a bearing platform integrally formed with the wall body, the upper surface of the bearing platform is parallel to the upper surface of the wall base, the side face of the bearing platform is a circular-arc-shaped plane perpendicular to the upper surface of the wall base, the circular-arc-shaped plane is provided with a pit for increasing the friction force between the bearing platform and the hillside soil, and an anchor device is fixedly connected to the back of the wall body. According to the balance weight type retaining wall, the stability and anti-overturning capability of the bearing platform in the hillside soil body can be greatly enhanced without increasing the size and the self-weight of the bearing platform.
Description
Technical field
The utility model relates to a kind of retaining wall, specifically a kind of balance weight retaining wall.
Background technology
Retaining wall is in order to ensure to banket or excavation position stability and the permanent or provisional wall of building or a class manual construction thing that is similar to wall.In the engineerings such as extensive utilization and highway, railway slope, the protection of hydraulic engineering bunding, building surrounding, tunnel, mine.
Retaining wall can divide a lot of classifications, can be divided into: curb wall, embankment wall, cutting wall, hillside wall, tunnel and open cut tunnel mouth retaining wall, bridge two ends barricade etc. by effect point; Divide and can be divided into by structure: gravity retaining wall, tied retaining wall, balance weight retaining wall, thin wall-type retaining wall, reinforced earth retaining wall, other retaining wall (pile and pland retaining wall, stake plate type retaining wall, cibretaining wall etc.).
The metope chest slope of balance weight retaining wall is very steep, and the lower wall back of the body is faced upward tiltedly, can reduce the height of wall, reduce excavation workload, avoid too affecting the stable of massif, sometimes can also utilize backstage headroom interception falling rocks, so balance weight retaining wall is often used in the kilometer of mountain area.Although it has many good qualities, but it is still not ideal enough aspect shock resistance, simultaneously, for increasing the supporting capacity of balance weight retaining wall, prior art is often by increasing the volume of weight platform with the lodging tolerance of raising retaining wall, thereby balance weight retaining wall volume, weight are obviously increased, increased construction period and construction cost.
Therefore,, for overcoming the above problems, need a kind of balance weight retaining wall that can obviously improve retaining wall resistance to capsizing.
Utility model content
In view of this, the purpose of this utility model is to overcome defect of the prior art, and one can obviously improve retaining wall resistance to capsizing, can not increase again the balance weight retaining wall of its volume, weight and construction period simultaneously.Balance weight retaining wall of the present utility model, comprise the wall base and be fixed on wall base upside for supporting the body of wall of the hillside soil body, the wall back of body of wall is provided with and the integrated bearing platform of body of wall, bearing platform upper surface is parallel with wall base upper surface, the side of bearing platform is the arc surface perpendicular to wall base upper surface, arc surface is provided with the pit for increasing bearing platform and hillside soil body frictional force, and the wall back of body of wall is fixedly connected with anchor device;
Further, the described wall base, body of wall and bearing platform are built moulding by steel concrete integral type;
Further, described anchor device comprises anchor pole and steel cable, and anchor pole is connected in the wall back of body of wall by steel cable;
Further, to be evenly provided with multiple and each anchor device along body of wall length direction mutually vertical with the wall back side of body of wall for described anchor device;
Further, described bearing platform evenly arranges multiple along body of wall length direction;
Further, on described body of wall, between two adjacent bearing platforms, be provided with the drain hole that connects metope side and wall dorsal part.
The beneficial effects of the utility model are: balance weight retaining wall of the present utility model, the side of bearing platform is the arc surface perpendicular to wall base upper surface, arc surface is provided with the pit for increasing bearing platform and hillside soil body frictional force, this structure can not increase under the prerequisite of bearing platform volume and deadweight, greatly strengthen the stability of bearing platform in slope soil, thereby increase the lodging tolerance of retaining wall, the wall back of body of wall is fixedly connected with anchor device simultaneously, further improves the supporting capacity of retaining wall to slope soil.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, balance weight retaining wall in the present embodiment, comprise the wall base 1 and be fixed on the wall base 1 upside for supporting the body of wall 3 of the hillside soil body, the wall back of body of wall 3 is provided with and the integrated bearing platform 6 of body of wall 3, bearing platform 6 upper surfaces are parallel with the wall base 1 upper surface, the side of bearing platform 6 is the arc surface perpendicular to the wall base 1 upper surface, arc surface is provided with the pit 7 for increasing bearing platform 6 and hillside soil body frictional force, the bearing platform 6 that employing side is arc surface can increase the contact area of bearing platform 6 and soil layer, increase the quantity of pit 7 simultaneously, the wall back of body of wall 3 is fixedly connected with anchor pole 5 and installs, wherein " the wall back of the body " is the one side of retaining wall towards the hillside soil body, " metope " is the retaining wall one side of the hillside soil body dorsad.
In the present embodiment, the described wall base 1, body of wall 3 and bearing platform 6 are built moulding by steel concrete integral type, because reinforced concrete structure intensity is higher, rigidity is larger, thereby its durability and fireproof performance, Mechanical Builds flexibly, globality, the good minimizing of ductility retaining wall own wt simultaneously, strengthen its anti-seismic performance.
In the present embodiment, described anchor device comprises anchor pole 5 and steel cable 4, anchor pole 5 is connected in body of wall 3 by steel cable 4, anchor pole 5 can be the steel tensile members being embedded in the soil body of hillside, also can adopt rig to hole on the soil body of hillside, insert after reinforcing bar, grouting forms anchoring body, and be connected with body of wall 3 by steel cable 4, rely on the horizontal pull that is anchored at the anchor pole 5 in the upward slope soil body to bear the lateral pressure of the soil body.
In the present embodiment, it is mutually vertical with the wall back side of body of wall that described anchor device evenly arranges multiple and each anchor device along body of wall 3 length directions, multiple anchor devices can greatly improve retaining wall to the supporting capacity of the hillside soil body and carrying reliability, the wall back side of each anchor device and body of wall 3 is mutually vertical can ensure that it is subject to axial tension minimum, difficult fracture.
In the present embodiment, described bearing platform 6 evenly arranges multiple along body of wall 3 length directions, bearing platform 6 is imbedded the lodging tolerance for increasing retaining wall in the soil body of hillside, pit 7 on bearing platform 6 arc surfaces is for strengthening its stability at soil layer, thereby multiple weighing unit can at utmost increase the stability of the quantity raising retaining wall of pit 7.
