Abstract
The utility model discloses a light gravity-type anti-earthquake concrete retaining wall, which aims at increasing stability of the earth wall and supplying good anti-earthquake capacity to the earth wall. The concrete retaining wall comprises a concrete wall body (10) poured along the sloping surface of the side slope. The light gravity-type anti-earthquake concrete retaining wall is characterized in that: anchor rods (20) are arranged at the upper slope surface in the earth body at the back of the wall body (10) in vertical/horizontal directions at intervals; the inner ends of the anchor rods (20) pass through the side slope earth fracture plane to be fixed with the stabilized earth body, and the outer ends are fixedly connected with the wall body (10). In the utility model, the integrity of the wall body is strengthened and the self-gravitation of the wall body is reduced by external force to increase the anti-earthquake capacity; the anchor rods are provided to increase the stability coefficient of the retaining wall; therefore, the anti-earthquake capacity of the retaining wall is increased, and the wall body is thinned; the existing gravity-type retaining wall is changed into the light gravity-type concrete retaining wall which is particularly suitable for high-intensity earthquake areas.
Description
Technical field
The utility model relates to the gravity retaining wall that is used for a rib slope in civil works, particularly a kind of light-duty gravity anti-seismic concrete retaining wall.
Background technology
Retaining wall is a kind ofly can resist lateral earth pressure, is used for supporting natural side slope or artificial side slope, keeps the building of soil stabilization.It is widely used in other civil workss such as highway, railway, water conservancy and building.Gravity retaining wall can be divided into gravity, weight formula, half gravity etc. by structure, and wherein gravity, weight formula are used barnacle more, and the concreting of half gravity optionally also can add a spot of reinforcing bar in the tensile region, to save bricklaying.
Existing gravity retaining wall is not because the stable soil body (rock mass) of its wall body and side slope constitutes stressed integral body, so its less stable, lacks necessary shock resistance.The seimic disaster census of " 5.12 " Wenchuan special violent earthquake shows that traditional gravity retaining wall destroys comparatively serious comparatively speaking, and failure mode mostly is the flare and the fracture of globality.
The utility model content
Technical problem to be solved in the utility model provides a kind of light-duty gravity anti-seismic concrete retaining wall, has good stable and shock resistance.
The technical scheme that its technical problem that solves the utility model adopts is: light-duty gravity anti-seismic concrete retaining wall, comprise the concrete wall body of building along side slope surface, it is characterized in that: the interior upper edge of the described wall soil body after one's death is domatic vertically, the lateral separation anchoring has anchor pole, the slope soil plane of fracture and stable soil body anchoring are passed in the inner of each anchor pole, and the outer end is then fixed with the wall body.
In technique scheme, be embedded with steel mesh reinforcement in the described wall body along domatic extension, fixedly connected with steel mesh reinforcement in each anchor pole outer end.
The beneficial effects of the utility model are, globality by strengthening the wall body and reduce himself gravity by external force and improve its shock resistance, and the stability coefficient that anchor pole increases barricade is set, improved the shock resistance of retaining wall, and attenuate the wall body, to have gravity retaining wall now and be modified to light-duty gravity concrete retaining wall, and be particularly suitable for using at high intensity Zone.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the cross-section structure schematic diagram of the light-duty gravity anti-seismic concrete of the utility model retaining wall;
Fig. 2 is the enlarged diagram of local A among Fig. 1.
Component, toponym and pairing mark among the figure: concrete wall body 10, steel mesh reinforcement 11, anchor pole 20, bending segment 20a.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, light-duty gravity anti-seismic concrete retaining wall, comprise the concrete wall body 10 of building along side slope surface, for the globality by strengthening wall body 10 with reduce himself gravity by external force and improve its shock resistance, and the stability coefficient of increase barricade, the interior upper edge of the soil body behind the described wall body 10 is domatic vertically, the lateral separation anchoring has anchor pole 20, and the slope soil plane of fracture and stable soil body anchoring are passed in the inner of each anchor pole 20, and the outer end is then fixed with wall body 10.
With reference to Fig. 2, for further strengthening the globality of wall body, be embedded with steel mesh reinforcement 11 in the described wall body 10 along domatic extension, fixedly connected with steel mesh reinforcement 11 in each anchor pole 20 outer end.Described anchor pole 20 is a reinforced anchor bolt, and the outer end of reinforced anchor bolt has the bending segment 20a that forms a fixed connection with steel mesh reinforcement 11, and the anchor hole 12 interior perfusions that penetrate in the soil body for anchor pole 20 are filled with cement mortar.Anchor pole 20, steel mesh reinforcement 11, wall body 10 threes become a stressed integral body, can further improve the shock resistance of retaining wall, and make wall body 10 be able to attenuate, will have gravity retaining wall now and be modified to light-duty gravity anti-seismic concrete retaining wall, become novel light-duty retaining structure.This light-duty retaining ruggedized construction has lot of advantages, and for example speed of application is fast, reduced investment, do not need heavy-duty machinery, not strict to the requirement of construction plant, to the pollution of environment with destroy for a short time, is particularly suitable for ungetable mountain area engineering.From this respect, these light-duty retaining ruggedized construction has good development trend and application prospect.
Some principles of the above light-duty gravity concrete retaining wall of the utility model that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
