Abstract
The utility model discloses an artesian water drainage pipe for a side slope. A cushion block (6) is arranged between an upper-layer fan-shaped water drainage pipe and a lower-layer fan-shaped water drainage pipe; a water drainage gap (9) is formed between the upper-layer fan-shaped water drainage pipe and a lower-layer fan-shaped water drainage pipe through the cushion block (6); a cylindrical plastic blind ditch pipe (3) is arranged in the upper-layer fan-shaped water drainage pipe; a permeable bed is coated on the cylindrical plastic blind ditch pipe (3); a water inlet hole (7) is formed in the lower-layer fan-shaped water drainage pipe horizontally; at least one filtering layer is coated on the lower-layer fan-shaped water drainage pipe and the permeable bed; and filter pieces are arranged at the tail ends of the upper-layer fan-shaped water drainage pipe, the lower-layer fan-shaped water drainage pipe, the cylindrical plastic blind ditch pipe (3) and the permeable bed. The artesian water drainage pipe can drain water fast and effectively and can prevent secondary infiltration.
Description
Technical field
The utility model relates to a kind of gutter.
Background technology
At present; Be used for the gutter that the underground water in field soil-slope such as highway, railway, Hydraulic and Hydro-Power Engineering and the sliding mass is discharged; Especially the gutter that the underground water that the soil-slope deep layer that is directed against distributes is discharged; All be that boring increases water permeability on gutter, the method at gutter outer wrap geotextile filtration soil body particle prevents the way that gutter stops up then, and its weak point is: 1) because the gutter percent opening is little; The free drainage scarce capacity of gutter, the pore water in can not effectively draining side slope body; 2) owing to all perforates around the gutter, the underground water that gets into from the gutter top is easy to infiltrate through the perforate formation secondary of gutter bottom, influences drainage effect.
The utility model content
The utility model technical problem to be solved provides a kind of quick, effective draining and prevents the side slope Artesian Drainage water pipe that secondary infiltrates.
In order to solve the problems of the technologies described above; The side slope Artesian Drainage water pipe that the utility model provides; Be provided with cushion block between the fan-shaped gutter of fan-shaped gutter in upper strata and lower floor; Be formed with the draining space through described cushion block between the fan-shaped gutter of fan-shaped gutter in described upper strata and lower floor; In the fan-shaped gutter in described upper strata, be provided with cylindrical plastic french drain tubing, be coated with pervious layer on the described cylindrical plastic french drain tubing, the fan-shaped drain level of described lower floor is provided with the inlet opening; The external surface of fan-shaped gutter of described lower floor and described pervious layer is enclosed with one deck filtration beds at least, and the tail end of the fan-shaped gutter in described upper strata, the fan-shaped gutter of lower floor, cylindrical plastic french drain tubing and pervious layer is provided with filter.
The fan-shaped gutter in described upper strata is the semicircle plastic drain-pipe of upper strata PVC, and the fan-shaped gutter of described lower floor is the semicircle plastic drain-pipe of the PVC of lower floor.
Described pervious layer is the porous pervious layer.
Described filtration beds is the geotextile filtration beds.
Described filter is the geotextile filter.
Adopt the side slope Artesian Drainage water pipe of technique scheme, upper strata not perforate of fan-shaped gutter, the water that directly will penetrate into from top the gutter is discharged sloping body; The fan-shaped drain level of lower floor is provided with the inlet opening, and the pore water in permission boring the latter half soil body enters into the draining space of the double-walled formation of gutter under pressure, discharges sloping body through the gravity flow mode then.Simultaneously through wrapping up in filtration beds outward and utilizing cylindrical plastic french drain tubing to prevent that gutter from stopping up.
The beneficial effect of the utility model is through utilizing increase drainage hole of cylindrical plastic french drain tubing and gutter contact surface area, to strengthen the pore water in the soil body gets into gutter through gravity and pressure effect ability; Through double-deck fan-shaped gutter of fan-shaped gutter in upper strata and lower floor is set, its at the middle and upper levels not perforate of the fan-shaped gutter water that directly will penetrate in the gutter discharge sloping body; Through at the fan-shaped drain level of lower floor the inlet opening being set, discharge outside the sloping body in the draining space that allows the pore water in the soil body of gutter bottom to infiltrate gutter through the inlet opening.This product structure design is reasonable, and processing and fabricating is simple, and is on-the-spot easy for installation, can improve the drainability of side slope by a relatively large margin, increases slope stability, saves construction costs.
The innovation part of the utility model is: utilize cylindrical plastic french drain tubing to increase the infiltration area; Improve the free-draining ability of gutter, realize quick, the effective draining of gutter and prevent the purpose that secondary infiltrates through the fan-shaped gutter of fan-shaped gutter in the upper strata that permeable and fluid-tight bilayer are set and lower floor simultaneously.
In sum, the utility model is a kind of quick, effective draining and prevents the side slope Artesian Drainage water pipe that secondary infiltrates.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Referring to Fig. 1 and Fig. 2; Be formed with draining space 9 through being provided with cushion block 6 between semicircle plastic drain-pipe 2 of upper strata PVC and the semicircle plastic drain-pipe 1 of the PVC of lower floor; In the semicircle plastic drain-pipe 2 of upper strata PVC, be provided with cylindrical plastic french drain tubing 3; Be coated with porous pervious layer 4 on the cylindrical plastic french drain tubing 3; Semicircle plastic drain-pipe 1 level of the PVC of lower floor is provided with inlet opening 7; The external surface of semicircle plastic drain-pipe 1 of the PVC of lower floor and porous pervious layer 4 is enclosed with 1～3 layer of geotextile filtration beds 5, and the tail end of the semicircle plastic drain-pipe 2 of upper strata PVC, the semicircle plastic drain-pipe 1 of the PVC of lower floor, cylindrical plastic french drain tubing 3 and porous pervious layer 4 is provided with geotextile filter 8.
Referring to Fig. 1 and Fig. 2, the semicircle plastic drain-pipe 2 not perforates of upper strata PVC, the water that directly will penetrate into from top the gutter is discharged sloping body; Semicircle plastic drain-pipe 1 level of the PVC of lower floor is provided with inlet opening 7, and the pore water in permission boring the latter half soil body enters into the draining space 9 of the double-walled formation of gutter under pressure, discharges sloping body through the gravity flow mode then.Simultaneously through the geotextile filtration beds wrapped up in outward 5 with utilize cylindrical plastic french drain tubing 3, geotextile filter 8 to prevent that gutter from stopping up.Through utilizing cylindrical plastic french drain tubing 3 to increase drainage hole and gutter contact surface area, strengthen the pore water in the soil body gets into gutter through gravity and pressure effect ability; Through semicircle plastic drain-pipe 2 of double-deck upper strata PVC and the semicircle plastic drain-pipe 1 of the PVC of lower floor are set, its at the middle and upper levels the semicircle plastic drain-pipe 2 not perforates of the PVC water that directly will penetrate in the gutter discharge sloping body; Through being horizontally disposed with inlet opening 7 at the semicircle plastic drain-pipe 1 of the PVC of lower floor, discharge outside the sloping body in the draining space that allows the pore water in the soil body of gutter bottom to infiltrate gutter through the inlet opening.This product structure design is reasonable, and processing and fabricating is simple, and is on-the-spot easy for installation, can improve the drainability of side slope by a relatively large margin, increases slope stability, saves construction costs.
