Abstract
The invention relates to a reinforced geogrid for earthwork, comprising a horizontal transverse rib belt and a longitudinal rib belt of single-way or dual-way geogrid. The upper part of the connection position of the horizontal transverse rib belt and the longitudinal rib belt of the geogrid is additionally provided with a cross plate component that is firmly connected with the grid such that the geogrid and the filling soil have anchoring effect. The geogrid of the invention is reasonably stress, and capable of greatly improving the reinforcing effect of the geogrid, thereby having excellent engineering application value and economic benefit.
Description
Technical field
The present invention relates to a kind of reinforced geo-technical grid, on establish anchoring type four-bladed vane, can strengthen the reinforcement effect of geo-grid.
Background technology
After proposing the reinforced earth notion in 1963, geotechnological reinforcement technology was used widely in geotechnical engineering from Henri Vidal in 1963.Geo-grid is one of geotechnological reinforcement material commonly used at present, is used for reinforced earth subgrade construction, ground processing and embankment slope protection works more.Yet the traditional geo-grid that adopts in present engineering is because of material or manufacture craft problem, and geo-grid is not given full play to the interaction of soil, and often ruptures in muscle band junction, influences the consolidation effect of geo-grid.
Summary of the invention
The object of the present invention is to provide a kind of reinforced geo-technical grid, in using, its engineering can anchoring type booster action take place with banketing, reinforced grille muscle band junction, and produce anchorage effect between banketing, can give full play to interaction with the soil body, the muscle material connects not easy fracture, thereby improves the reinforcement effect of geo-grid.
For achieving the above object, the present invention adopts following technical proposals to realize:
1). above-mentioned a kind of reinforced geo-technical grid, the horizontal horizontal bar band (1) and the vertical muscle band (2) that comprise unidirectional or two-way geo-grid, it is characterized in that horizontal horizontal bar band (1) in described geo-grid adds with grid with vertical muscle band (2) top, junction is connected firm four-bladed vane member (3), makes geo-grid and bankets the generation anchorage effect.
2). above-mentioned reinforced geo-technical grid, carve at the muscle belt surface and to establish wavy or grid-like coarse striped or coarse salient point (4), increase and soil between friction force.
3). above-mentioned reinforced geo-technical grid, increase muscle material thickness in horizontal, vertical muscle band junction, rinforcement bar band connecting portion (5), geo-grid material can be chosen the condensate of plastics or rubber.
The present invention compared with prior art, have the following advantages: 1, four-bladed vane member (3) is laid on geo-grid top, make geo-grid and banket between produce anchorage effect, increase native muscle active layer thickness, form the soil mass consolidation zone on geo-grid top, strengthen its reinforcement effect.2, establish wavy, grid-like coarse striped or coarse salient point (4) quarter at geo-grid muscle belt surface, can increase rubbing action between the muscle material and the soil body, make the reinforcement effect of geo-grid more obvious.3, take reinforcement measure in geo-grid horizontal stroke, vertical muscle band junction (3), can avoid the muscle band to concentrate and rupture, prolong the working life of geo-grid because of junction stress.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
Referring to accompanying drawing, a preferred embodiment of the present invention is described as follows in conjunction with Fig. 1: the reinforced geo-technical grid should upwards carry out the scene to the one side that is provided with four-bladed vane 3 and lay, back fill course carries out mechanical ramming after surpassing 2～3 times of four-bladed vane 1 height, and it is identical with common geo-grid that steps are laid in other job sites.
This reinforced geo-technical grid, the horizontal horizontal bar band 1 and the vertical muscle band 2 that comprise unidirectional or two-way geo-grid, add with grid with top, vertical muscle band 2 junction at the horizontal horizontal bar band 1 of described geo-grid and to be connected firm four-bladed vane member 3, make geo-grid and banket the generation anchorage effect.
Carve on the surface of above-mentioned horizontal bar band 1 and vertical muscle band 2 and to establish wavy or grid-like coarse striped or coarse salient point 4, increase and soil between friction force.
Increase the muscle tape thickness in horizontal bar band 1 and vertical muscle band 2 junctions, form enhancement mode and connect transitional region 5, rinforcement bar band connecting portion.
Claims (3)
1, a kind of reinforced geo-technical grid, the horizontal horizontal bar band (1) and the vertical muscle band (2) that comprise unidirectional or two-way geo-grid, it is characterized in that horizontal horizontal bar band (1) in described geo-grid adds with grid with vertical muscle band (2) top, junction is connected firm four-bladed vane member (3), makes geo-grid and bankets the generation anchorage effect.
2, a kind of reinforced geo-technical grid according to claim 1 is characterized in that carving on the surface of described horizontal bar band (1) and vertical muscle band (2) and establishes wavy or grid-like coarse striped or coarse salient point (4), increase and soil between friction force.
3, a kind of reinforced geo-technical grid according to claim 1 is characterized in that increasing the muscle tape thickness in horizontal bar band (1) and vertical muscle band (2) junction, forms enhancement mode and connects transitional region (5), rinforcement bar band connecting portion.
