Abstract
The utility model relates to a same-width S-shaped drainage pipe (1) with infiltrating holes (2), the similar bending portions of two adjacent drainage pipes are welded, pressed, casted, sleeved, banded and connected to form a seepage-drainage geotechnical grille (4) which is paved on differnet layers of foundations in the construction of road foundation engeerning, residual water in road foundations generated by rainwater, ice and snow smelting, variaton of underground water and seasonal freezing is drained, and the stability of foundations and the service span of roads are guaranteed.
Description
Technical field: highway construction.In the road project construction, the levels different at road foundation lay reinforced grille.
Background technology: this patent be utilize road foundation build in different levels, lay reinforced grille.Road foundation has strict control requirement to moisture content, its water content too high stability and application life that will have a strong impact on road foundation, oozes under rainwater, the ice dissolution; WATER LEVEL CHANGES; The freeze thawing in season all will influence the moisture content of road foundation.
Summary of the invention: can reinforce road foundation on this patent structure, can get rid of the moisture in the road foundation simultaneously, guarantee the stability of road foundation and the application life of roadbed.Seepage and drainage geogrid is to be laid in to be used to strengthen the roadbed globality in the road foundation and to have the plastic grill that drain function is oozed in roadbed inside, grid is through being connected to form net structure by the hollow gutter that has the hole of seeping water, it is by having infiltration hole flexible water drainage pipe, adjacent drainage channel pipe multiple spot is linked in sequence to constitute through machinery and oozes drainage grill, the gutter that it is characterized in that constituting grid is flexible, and two adjacent gutter intercommunications constitute grids.
Gutter is by plastics, the manufacturing of rubber and plastic macromolecular material, rough surface, and uniform miniature infiltration hole forms gutter on the tube wall, and gutter is flexible, and the adjacent drainage channel pipe is is equidistantly connected and composed by welding, die casting, sleeve pipe, colligation and oozes drainage grill.The different aspects that are tiled in roadbed in construction become equidistant grid.Can reinforce road foundation on this patent structure, can get rid of the moisture in the road foundation simultaneously, guarantee the stability of road foundation and the application life of roadbed.
Description of drawings: the present invention is further described below in conjunction with accompanying drawing
Fig. 1 is the seepage and drainage geogrid structure chart
Fig. 2 oozes draining building grid cable laying operation figure
Fig. 3 oozes connector between draining building grid gutter
Figure explanation: connector (8), above-ground route (6), pavement of road (7) between gutter (1), infiltration hole (2), roadbed (3), infiltration building grid (4), drainage outlet (5), gutter.
Embodiment: this patent relates to a kind of flexible water drainage pipe (1) that has the hole of seeping water, and gutter (1) is connected the adjacent drainage channel pipe with the equidistant many places of gutter (1) by welding, die casting, outer tube or binding wire and forms grid (4).Be used for the reinforcing of road foundation soil layer.In road foundation engineering construction process, form grid equidistant, that link to each other at roadbed different aspects grid, combine closely with roadbed.
Claims (6)
1, seepage and drainage geogrid is through being connected to form net structure by the hollow gutter that has the hole of seeping water, it is by having infiltration hole flexible water drainage pipe, adjacent drainage channel pipe multiple spot is linked in sequence to constitute through machinery and oozes drainage grill, the gutter that it is characterized in that constituting grid is flexible, and two adjacent gutter intercommunications constitute grids.
2, it is characterized in that according to the described seepage and drainage geogrid of claim 1 the seepage and drainage geogrid net is that gutter forms grid in the junction by the connected mode of die casting, welding, sleeve pipe, colligation.
3, it is characterized in that according to the described seepage and drainage geogrid of claim 1 uniform miniature infiltration hole forms gutter on the tube wall.
4, it is characterized in that being laid on the different aspects of roadbed according to the described seepage and drainage geogrid of claim 1, the equidistant many places of gutter connect the adjacent drainage channel pipe by welding, die casting, outer tube or binding wire and form grid, are used for the reinforcing of road foundation soil layer.
5, it is characterized in that according to the described seepage and drainage geogrid of claim 1 the adjacent drainage channel pipe is connected through welding, die casting, sleeve pipe, colligation realization tube chamber internal run-through in the junction.
6, it is characterized in that according to the described seepage and drainage geogrid of claim 1 the gutter external surface is coarse.
