Abstract
The invention discloses a slope shallow drainage system, an underlying platform of a slope (6) is provided with a drainage ditch (4), multiple rows and multiple columns of drainage drilled holes (1) are densely arranged on the slope (6), the distance between the drainage drilled holes (1) is 2-3m, the depth of each drainage drilled hole (1) is 3-4m, the elevation angle of each drainage drilled hole (1) is 0-10 degrees, a drainage pipe is arranged in each drainage drilled hole (1), longitudinal micro-collecting ditches (2) and/or transverse micro-collecting ditches (3), which are respectively in butt joint with outlets of the drainage pipes, are arranged on the slope surface of the slope (6), and the longitudinal micro-collecting ditches (2) and/or the transverse micro-collecting ditches (3) are communicated with the drainage ditch (4). The slope shallow drainage system provided by the invention can discharge rainfall in a fast and high-efficient manner and enable the rainfall to infiltrate into underground water in a slope shallow soil body.
Description
Technical field
The technology of the present invention relates to field side slope superficial Drainage Design and construction technologies such as being used for highway, railway, Hydraulic and Hydro-Power Engineering, especially at the sloping body draining of soil-slope under the condition of raining.
Background technology
Under the prior art condition, for a large amount of soil-slopes, the slope drainage system generally adopts in domatic layout gutter and sloping body the mode of arranging the deep layer gutter to discharge the underground water of rainfall infiltration in the sloping body.Most of engineerings are only arranged several rows of water hole in the bottom of first order side slope, and a small amount of engineering adopts the drain hole of arranging row's degree of depth 5～10m on the step of each grade side slope.The weak point of its worker's method is because gutter negligible amounts in the drainage system can not in time be discharged the underground water of rainfall infiltration in the sloping body, has a strong impact on the drainage effect in the side slope body, causes the side slope unstable failure easily.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rainfall infiltration of rapidly and efficiently discharging to the interior phreatic side slope superficial drainage system of the side slope superficial soil body.
In order to solve the problems of the technologies described above, side slope superficial drainage system provided by the invention, the underlying platform of side slope is provided with the gutter, intensive layout is arranged the drainage hole of multiple row more on described side slope, distance between the described drainage hole is 2～3m, the degree of depth of described drainage hole is 3～4m, the elevation angle of described drainage hole is 0～10 °, in each described drainage hole, be provided with gutter, the domatic vertical miniature collecting gutter and/or the transverse miniature collecting gutter that docks with the outlet of each described gutter that be furnished with of described side slope, described vertical miniature collecting gutter and/or transverse miniature collecting gutter are communicated with described gutter.
Be staggeredly arranged between the described drainage hole of upper and lower row.
Every grade of described gutter of side slope basecoat exceeds underlying platform 20～30cm.
Described gutter is the high porosity gutter.
The section of described vertical miniature collecting gutter and transverse miniature collecting gutter is 20cm * 10cm.
The elevation angle of described drainage hole is 5～10 °.
The diameter of described drainage hole is 75～110mm.
Adopt the side slope superficial drainage system of technique scheme, dwindle spacing between the drainage hole by many rows drainage hole is set on every grade of side slope, system is arranged in the drainage hole that forms higher density, realizes strengthening drainage effect, strengthens the purpose of drain discharge; By the length of reasonable shortening gutter, both guaranteed the drainability of gutter, again reasonable Control Engineering cost.By miniature collecting gutter being set domatic, prevent from that underground water that gutter flows out from infiltrating by domatic secondary to enter sloping body, also can play the domatic effect of being washed away that prevents simultaneously.This shallow-layer drainage system technological design is reasonable, and job practices is simple, can improve the drainability and the erosion resistibility of side slope by a relatively large margin, reduces corresponding support reinforcement measure, increases slope stability, saves construction costs.
Innovation part of the present invention is: fast, efficiently discharge the underground water that penetrates in the soil body shallow-layer by the drainage hole that intensive depth of placement on side slope is little, at slope surface miniature gutter is set the water body that gutter flows out is incorporated in the gutter, prevent domatic being washed away.
In sum, the present invention is that a kind of rainfall infiltration of rapidly and efficiently discharging is to the interior phreatic side slope superficial drainage system of the side slope superficial soil body.
Description of drawings
Fig. 1 is the facade arrangement diagram of side slope superficial drainage system;
Fig. 2 is the sectional view of side slope superficial drainage system.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, the underlying platform of side slope 6 is provided with gutter 4, intensive layout is arranged the drainage hole 1 of multiple row more on side slope 6, on, be staggeredly arranged between following row's the drainage hole 1, distance between the drainage hole 1 is 2～3m, the degree of depth of drainage hole 1 is 3～4m, the diameter of drainage hole 1 is 75～110mm, the elevation angle of drainage hole 1 is 0～10 °, the best elevation angle is 5～10 °, in each drainage hole 1, be provided with high porosity gutter 5, the high porosity gutter 5 of side slope 6 basecoats exceeds underlying platform 20～30cm, the domatic vertical miniature collecting gutter 2 and the transverse miniature collecting gutter 3 of being furnished with of side slope 6, the section of vertical miniature collecting gutter 2 and transverse miniature collecting gutter 3 is 20cm * 10cm, the outlet of each high porosity gutter 5 is all docked with vertical miniature collecting gutter 2 or transverse miniature collecting gutter 3, and vertical miniature collecting gutter 2 and transverse miniature collecting gutter 3 are communicated with gutter 4.
Referring to Fig. 1 and Fig. 2, by intensive depth of placement on side slope 6 little drainage hole 1 and high porosity gutter 5 quick, efficient underground water of discharging in the soil body shallow-layer that penetrates into side slope 6, the water body that vertical miniature collecting gutter 2 that is provided with on the surface of side slope 6 and transverse miniature collecting gutter 3 flow out high porosity gutter 5 is incorporated in the gutter 4 and is discharged to outside the side slope 6, prevents domatic being washed away.
