Technical field
The utility model belongs to the building body structure, is a kind of composite protection structure that utilizes reinforcing bar wire side anti-package formula Geogrid Reinforced Earth Retaining Wall to coordinate the reinforcing bar wire side barricade of strengthening with prestressed anchor specifically.
Background technology
The reinforced earth bulkhead principle is the soil pressure that relies on the frictional force between filler and lacing wire to come the balance metope to bear.Traditional reinforced earth bulkhead is by beam, baffle plate, muscle band and the common gear soil composite construction that forms that bankets, and the defective that this structure exists has:
One, the beam impact that arranges in the barricade face wall is attractive in appearance, and can not carry out ecological afforestation;
Two, need long muscle band is set, cause the horizontal cross filler thicker, this not only increases labor and materials, and is also inapplicable in some engineerings;
When three, reinforced structure is higher, prefabricated units is installed is used crane gear, otherwise need the cast in situs member;
Four, when not enough, need to add antiskid structure when the stability against sliding of reinforced earth bulkhead or resistance to overturning, engineering cost is increased;
Five, when the barricade face wall produces larger side to distortion, repair more difficult.
Thereby, need a kind of novel project organization to make up defects, to coordinate the progress of engineering construction, satisfy its construction standard.
The utility model content
The technical problem that the utility model solves is to provide a kind of composite protection structure of reinforcing bar wire side barricade, this NEW TYPE OF COMPOSITE safeguard structure saves that material, cost are low, wide accommodation, simultaneously easy construction, ecological, environmental protective effect are also comparatively obvious, can solve the defective in above-mentioned technical background.
The technical problem that the utility model solves adopts following technical method to realize:
a kind of composite protection structure of reinforcing bar wire side barricade, formed by reinforcing bar wire side anti-package formula Geogrid Reinforced Earth Retaining Wall and prestressed anchor, wherein, described reinforcing bar wire side anti-package formula Geogrid Reinforced Earth Retaining Wall is comprised of a plurality of reinforcing bar wire side anti-package formula geo-grid unit, the muscle rib of each geo-grid unit intersects and passes the reinforcing bar wire side, thereby form an integral body, simultaneously, each unit comprises the reinforcing bar wire side, geo-grid, triangle support frame, geotextiles is given birth to pad with planting, after its geo-grid is set up in the reinforcing bar wire side, and make moulding by triangle support frame, and this triangle support frame should be no less than two in each geo-grid unit, and reinforcing bar wire side inboard also is provided with and is no less than planting of one deck and gives birth to pad and geotextiles, prevent from banketing when being used for construction spill with moulding after prevent erosion, in addition, described prestressed anchor tilts at the reinforcing bar wire side and squeezes into, and interconnects with the reinforcing bar wire side, and is applied with prestressing force at the end face of prestressed anchor.
In the utility model, the reinforcing bar wire side of adjacent reinforcing bar wire side anti-package formula geo-grid unit can weld, and geo-grid can be connected by pitman.
In the utility model, but the triangle support frame flexible rotating after the reinforcing bar wire side, thus the angle of adjustment reinforcing bar wire side and horizontal plane.
In the utility model, must reinforce the connection to guarantee its intensity between each adjacent cells of described geo-grid unit; Described reinforcing bar wire side and horizontal plane angle can be according to the actual conditions adjustment.
In the utility model, described prestressed anchor must pass the Potential failure surface of reinforced earth bulkhead, and the anchor head of prestressed anchor is cross, can overlap well anchor pole with the reinforcing bar wire side, is in the stress range that can bear to guarantee stress surface.
Loading characteristic of the present utility model is: when the lateral pressure of banketing was delivered to the face wall of reinforcing bar wire side anti-package formula Geogrid Reinforced Earth Retaining Wall, a part was by prestressing force and the uplift resistance balance of prestressed anchor; Another part is delivered to geo-grid muscle material by face wall, by geo-grid and the frictional force between banketing come balance.Due to the existence of prestressed anchor, greatly increased barricade stability against sliding and stability against overturning, reduced the lateral deformation of barricade face wall.
Advantage of the present utility model and beneficial effect are:
1. Geogrid Reinforced Earth Retaining Wall+the prestressed anchor composite protection structure is lower to the ground requirement for bearing capacity for reinforcing bar wire side anti-package formula of the present utility model, applicable to the lower unfavorable foundation area of bearing capacity, also can adapt to preferably the differential settlement of ground;
2. reinforcing bar wire side anti-package formula Geogrid Reinforced Earth Retaining Wall of the present utility model+prestressed anchor composite protection structure can be controlled preferably the lateral deformation of face wall, and can realize the ecological afforestation of face wall;
But 3. the equal precast assembly of main member of the present utility model, construction technology is simple, is convenient to grasp, and all construction operations can be completed in a side of banketing, and also needn't drop into a large amount of man power and materials in maintenance;
4. reinforcing bar wire side anti-package formula Geogrid Reinforced Earth Retaining Wall of the present utility model+prestressed anchor composite protection structure is saved labor and materials, and cost is lower, and has the characteristic of free drainage.
