Abstract
The utility model relates to a double-T-shaped stereoscopic geogrid. Transverse ribs and longitudinal ribs of the geogrid are T-shaped stereoscopic components, and meshing force and frictional force of the transverse ribs and soil (sand) can be increased, so that transverse and longitudinal pulling force of the geogrid can be increased remarkably. The T-shaped stereoscopic transverse ribs (1) and T-shaped stereoscopic longitudinal ribs (2) enhance stability of reinforcing structures and stereoscopic reinforcing effect. The double-T-shaped stereoscopic geogrid is a novel geogrid perfectly combining a common geogrid with a geocell and integrating the advantages of the common geogrid and the geocell, is reasonable in stress, and has fine engineering application value and economic benefits, and the reinforcing effect of the geogrid can be improved substantially.
Description
Technical field
The utility model relates to a kind of double-T shaped solid geogrid, and the cross rib of this geo-grid and vertical rib are the three-dimensional member of T type, can significantly strengthen the reinforcement effect of geo-grid.
Background technology
Geosynthetics is able to extensive use after mid-term in 20th century, enter China the eighties, development rapidly, present geotechnological reinforcement technology is used widely in water conservancy, railway, highway, harbour and construction work, solve the technical barrier in many civil workss, obtained good society and economic benefit.Geo-grid is used for reinforced earth subgrade construction, ground processing and embankment slope protection works as a kind of reinforcement material 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, has a strong impact on the reinforcement effect of geo-grid.
The utility model content
The purpose of this utility model is to provide a kind of double-T shaped solid geogrid, makes its pulling capacity that can significantly increase grid in engineering is used, and improves the reinforcement effect of geo-grid.
For achieving the above object, the present invention adopts following technical proposals to realize:
A kind of double-T shaped solid geogrid comprises the cross rib and the vertical rib of unidirectional or two-way geo-grid, it is characterized in that the horizontal cross rib of described geo-grid and vertical rib are the three-dimensional member of T type, form double-T shaped solid geogrid.
Above-mentioned double-T shaped solid geogrid because described cross rib and vertical rib are the three-dimensional member of T type, thereby increases the snap-in force between rib and the soil (sand), has increased the horizontal and vertical pulling capacity of grid simultaneously.
Above-mentioned double-T shaped solid geogrid, three-dimensional cross rib of its T type and vertical rib have increased the stability of reinforced structure, have strengthened three-dimensional reinforcement effect.
Above-mentioned double-T shaped solid geogrid is the perfect adaptation of common geo-grid and geotechnical grid, integrates a kind of novel geo-grid of both advantages.
In the above-mentioned double-T shaped solid geogrid, the material that the optional friction factor of its member is big or by increasing its surface roughness, thereby increase with native (sand) between frictional force.Geo-grid material can be chosen the condensate of plastics or rubber etc.
The utility model has the following advantages compared with prior art: 1, the cross rib of geo-grid and vertical rib are the three-dimensional member of T type, thereby have increased native muscle active layer thickness, have increased the snap-in force of cross rib, strengthen its reinforcement effect.2, the material that the optional friction factor of T type rib is big or by increasing its surface roughness, thus increase with native (sand) between frictional force, make the reinforcement effect of geo-grid more obvious.3, adopt T type rib simultaneously on cross rib and the vertical rib, thereby increased the horizontal and vertical pulling capacity of grid simultaneously, can strengthen the effect of two-way reinforcement.4, described cross rib and vertical rib adopt the three-dimensional rib of T type, have increased the stability of reinforced structure, have strengthened three-dimensional reinforcement effect.5, described cross rib and vertical rib adopt T type rib simultaneously, are characterised in that it is the perfect adaptation of common geo-grid and geotechnical grid, integrate a kind of novel geo-grid of both advantages.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Referring to accompanying drawing, a preferred embodiment accompanying drawings of the present utility model is as follows: this double-T shaped solid geogrid, the cross rib 1 and the vertical rib 2 that comprise unidirectional or two-way geo-grid, the cross rib 1 of described geo-grid and vertical rib 2 are the three-dimensional member of T type, form double-T shaped solid geogrid.
Above-mentioned cross rib 1 and vertical rib 2 are the three-dimensional member of T type, thereby increase the snap-in force between rib and the soil (sand).
Above-mentioned cross rib 1 and vertical rib 2 are the three-dimensional member of T type simultaneously, thereby have increased the horizontal and vertical pulling capacity of grid simultaneously.
Above-mentioned cross rib 1 and vertical rib 2 are the three-dimensional member of T type, have increased the stability of reinforced structure, have strengthened three-dimensional reinforcement effect.
Above-mentioned cross rib 1 and vertical rib 2 are the three-dimensional member of T type, are the perfect adaptations of common geo-grid and geotechnical grid, integrate a kind of novel geo-grid of both advantages.
Above-mentioned cross rib 1 and vertical rib 2 are the three-dimensional member of T type, the material that optional friction factor is big or by increasing its surface roughness, thereby increase with native (sand) between frictional force.
Double-T shaped solid geogrid should carry out the scene to T type rib up to be laid, and back fill course carries out mechanical ramming after surpassing 2～3 times of the three-dimensional rib height of T type, and it is identical with common geo-grid that steps are laid in other job sites.
