Abstract
The invention discloses a grouted geogrid, which comprises geogrids, wherein a plurality of grouting pipes which are arranged in parallel at certain intervals are arranged in a geogrid plane; the geogrids and the grouting pipes are integrally-molded pieces; and the grouting pipes are provided with a plurality of grouting holes at certain intervals along the length directions of the grouting pipes. According to the grouted geogrid, the grouting pipes in the geogrids are connected with a grouting machine, and grout is grouted into soil bodies close to the geogrids through the grouting pipes and the grouting holes for reinforcing; meanwhile, the bearing capability and tensile strength of the geogrids can be enhanced after grouting; the grouting pipes and the geogrids are molded integrally, so that grouting pipelines are not required to be arranged separately during grouting, construction procedures are simplified, and construction cost and engineering cost are reduced; and the grouted geogrid is simple in structure, has a good use effect, and is applied to the technical field of geogrids.
Description
Technical field
The present invention relates to the geo-grid technical field, particularly a kind of geo-grid for ground stabilization.
Background technology
In the prior art, adopting slip casting method is the common method that engineering foundation is reinforced, slip casting method is some slurries that can solidify to be injected crack or the hole of Rock soil Foundation, to improve the method for its physico-mechanical properties, be widely used at present the dam foundation, foundations, roadbed, the antiseepage of underground building, leak stopping, reinforcing and correction engineering etc., and geo-grid also is widely used in highway as the ground stabilization material, railway, the airport, the treatment of soft foundation of water conservancy etc. and side slope, dykes and dams, shore protection, the engineerings such as road widening, utilize at present geo-grid and adopt slip casting method to carry out ground stabilization and all obtained widely engineering application, but slip casting generally all is the Grouting Pipe by special use, exists cost high, the shortcomings such as construction complexity and operation are many.
Summary of the invention
Technical problem to be solved by this invention provides a kind of slip casting type geo-grid with slip casting function simple in structure.
For solving the problems of the technologies described above the technical scheme that adopts: a kind of slip casting type geo-grid, comprise geo-grid, in the geo-grid plane, be provided with the Grouting Pipe of some spacing parallel arrangings, geo-grid and the Grouting Pipe part that is formed in one has some injected holes along Grouting Pipe length direction interval on Grouting Pipe.
Be further used as improvement of the present invention, the aperture direction of adjacent injected hole staggers mutually.
Be further used as improvement of the present invention, the aperture direction of adjacent injected hole staggers into 90 degree mutually.
Be further used as improvement of the present invention, geo-grid is unidirectional geo-grid, direction earthwork grille or three-dimensional geogrid.
Be further used as improvement of the present invention, geo-grid and Grouting Pipe adopt high density polyethylene (HDPE) or polypropylene material to make.
Beneficial effect: this slip casting type geo-grid is by linking to each other the Grouting Pipe in the geo-grid with slurry filling machine, slurries carry out grouting and reinforcing through Grouting Pipe and injected hole near the soil body the geo-grid, also can improve supporting capacity and the tensile strength of geo-grid after the simultaneously slip casting, because Grouting Pipe and geo-grid are formed in one, improved the tensile strength of geo-grid, when carrying out slip casting, do not need to arrange separately grouting pipe, simplify working procedure, construction cost and engineering cost have been reduced, simple in structure, result of use is good.

This slip casting type geo-grid is by linking to each other the Grouting Pipe 1 in the geo-grid 2 with slurry filling machine, near the soil body of slurries Grouting Pipe 1 and 11 pairs of geo-grid of injected hole 2 carries out grouting and reinforcing, also can improve supporting capacity and the tensile strength of geo-grid 2 after the simultaneously slip casting, because Grouting Pipe 1 is formed in one with geo-grid 2, improved the tensile strength of geo-grid 2, when carrying out slip casting, do not need additionally to arrange grouting pipe, simplify working procedure, construction cost and engineering cost have been reduced, simple in structure, result of use is good.
As preferred embodiment of the present invention, the aperture direction of adjacent injected hole 11 staggers mutually.
As preferred embodiment of the present invention, the aperture direction of adjacent injected hole 11 staggers into 90 degree mutually.
On Grouting Pipe 1, have injected hole 11 every 10～20cm interval, the pore size of injected hole 11 is 0.5～0.8cm, its aperture direction staggers angled mutually, and preferably 90 spend, so that slurries can be reinforced near the soil bodys the geo-grid 2 by uniform-flow.
As preferred embodiment of the present invention, geo-grid 2 is unidirectional geo-grid, direction earthwork grille or three-dimensional geogrid.
As preferred embodiment of the present invention, geo-grid 2 and Grouting Pipe 1 adopt high density polyethylene (HDPE) or polypropylene material to make.
It is one-body molded that raw material is made that geo-grid 2 and Grouting Pipe 1 can adopt the materials such as high density polyethylene (HDPE) or polypropylene, certainly can also adopt such as other materials such as glass fiber and make.
The above has done detailed description to embodiments of the present invention by reference to the accompanying drawings, but the invention is not restricted to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, can also under the prerequisite that does not break away from aim of the present invention, make various variations.
