Abstract
The utility model discloses a double-wall self-flowing draining pipe for a side slope. A draining clearance is formed by arranging a cushion block (6) between an upper-layer fan-shaped draining pipe and a lower-layer fan-shaped draining pipe; a cylindrical plastic blind ditch pipe (3) is arranged inside the upper-layer fan-shaped draining pipe; a water-permeable layer is covered on the cylindrical plastic blind ditch pipe (3); a water inlet (7) is horizontally formed in the lower-layer fan-shaped draining pipe; at least one filtering layer is coated on the outer surfaces of the lower-layer fan-shaped draining pipe and the water-permeable layer respectively; and filtering sheets are arranged at the tail ends of the upper-layer fan-shaped draining pipe, the lower-layer fan-shaped draining pipe, the cylindrical plastic blind ditch pipe (3) and the water-permeable layer. The double-wall self-flowing draining pipe for the side slope which can drain water and prevent secondary penetration quickly and effectively.
Description
Technical field
The utility model relates to a kind of gutter, particularly relate to the side slope double-walled Artesian Drainage water pipe that underground water that side slope double-walled Artesian Drainage water pipe, especially at soil-slope deep layer that a kind of underground water that is used in field soil-slope such as highway, railway, Hydraulic and Hydro-Power Engineering and the sliding mass discharges distribute is discharged.
Background technology
Under the prior art condition, deep phreatic water in the side slope body is discharged and handled used gutter all is that boring increases water permeability on gutter, method at gutter outer wrap geotextile filtration soil body particle prevents the way that gutter stops up then, 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 enters from the gutter top is easy to infiltrate by the perforate formation secondary of gutter bottom, influences drainage effect.
The utility model content
Technical problem to be solved in the utility model provides a kind of quick, effective draining and prevents the side slope double-walled Artesian Drainage water pipe that secondary infiltrates.
In order to solve the problems of the technologies described above, the side slope double-walled Artesian Drainage water pipe that the utility model provides, be formed with the draining space by being provided with cushion block between the fan-shaped gutter of fan-shaped gutter in 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, the fan-shaped gutter in described upper strata, the fan-shaped gutter of lower floor, the tail end of 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 double-walled Artesian Drainage water pipe of technique scheme, upper strata not perforate of fan-shaped gutter, directly the water that 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 by the gravity flow mode then.Simultaneously by wrapping up in filtration beds outward and utilizing cylindrical plastic french drain tubing to prevent that gutter from stopping up.
The beneficial effects of the utility model are to increase drainage hole and gutter contact surface area by utilizing cylindrical plastic french drain tubing, the pore water in the enhancing soil body enters gutter by gravity and pressure effect ability; By 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; By 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 by 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.
Innovation part of the present 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 by 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 double-walled Artesian Drainage water pipe that secondary infiltrates.
