Abstract
The utility model discloses a drainage system for a reconstructed and expanded expressway soil slope shallow layer. A side ditch (6) is formed in a bottom platform of a side slope (1), the side slope (1) is provided with drainage holes (2), a longitudinal drainage pipe (3) is arranged inside each drainage hole (2), and the lower ends of the longitudinal drainage pipes (3) are communicated with transverse drainage pipes (4). A longitudinal water collecting ditch (7) and/or a transverse water collecting ditch (5) in butt joint with the outlet of each transverse drainage pipe (4) is formed in the surface of the side slope (1), and the longitudinal water collecting ditch (7) and the transverse water collecting ditch (5) are communicated with the side ditch (6). The drainage system for the reconstructed and expanded expressway soil slope shallow layer can fast and effectively drain underground water in the soil body of the reconstructed and expanded expressway soil slope shallow layer.
Description
Technical field
The utility model relates to a kind of slope of highway drainage system, and a kind of reorganization and expansion speedway soil-slope shallow-layer drainage system particularly, for reorganization and expansion speedway soil-slope shallow-layer drainage system, especially for the slope body draining of soil-slope under condition of raining.
Background technology
At present, be directed to reorganization and expansion speedway soil-slope, the slope drainage system is general to be adopted at the domatic catchwater, toe of arranging and gutter is set drains the mode that adopts french drain and drain hole in surface water and slope body and discharge rainfall infiltration to the underground water in the body of slope.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 5m left and right on the step of every one-level side slope.The weak point of this design is gutter negligible amounts in designed drainage system, in the process of side slope experience heavy showers, the slope drainage facility can not fully meet the requirement of draining, have a strong impact on the drainage effect in the side slope body, easily cause that slope instability destroys.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of reorganization and expansion speedway soil-slope shallow-layer drainage system of rapidly and efficiently discharging rainfall infiltration interior underground water to the side slope superficial soil body.
In order to solve the problems of the technologies described above, the reorganization and expansion speedway soil-slope shallow-layer drainage system that the utility model provides, the underlying platform of side slope is provided with gutter, be furnished with drain hole on described side slope, be provided with the longitudinal drainage pipe in each described drainage hole, the lower end of described longitudinal drainage pipe is communicated with transverse drain, domatic vertical collecting gutter and/or the horizontal collecting gutter docked with the outlet of each described transverse drain that be furnished with of described side slope, described vertical collecting gutter and horizontal collecting gutter are communicated with described gutter.
Each arranges described drainage hole interlaced arrangement.
Distance between described drainage hole is 3.0m, and the degree of depth is 1.0m.
Every grade of described transverse drain of side slope basecoat exceeds underlying platform 30cm.
Described longitudinal drainage pipe and transverse drain are the flexible porous bellows of high porosity.
The section of described vertical collecting gutter and horizontal collecting gutter is 10cm * 10cm.
The diameter of described drainage hole is 110mm.
The length of the inner described transverse drain arranged of side slopes at different levels increases from top to down successively.
Adopt the reorganization and expansion speedway soil-slope shallow-layer drainage system of technique scheme, by the longitudinal drainage pipe is set on every grade of side slope, in time the rainwater of rainfall infiltration is confluxed fast and enters transverse drain, then enter in gutter by longitudinal and transverse collecting gutter.By the length of gutter rationally is set, both guaranteed the drainability of gutter, again can rational control of engineering cost.By domatic longitudinal and transverse collecting gutter being set, prevent that the underground water that gutter flows out from infiltrating and entering the slope body by domatic secondary, also can play the domatic effect be washed that prevents simultaneously.This shallow-layer drainage system technological design is reasonable, and job practices is simple, can improve by a relatively large margin drainability and the erosion resistibility of side slope, reduces corresponding support reinforcement measure, improves slope stability, saves construction costs.
In sum, the utility model is a kind of reorganization and expansion speedway soil-slope shallow-layer drainage system of rapidly and efficiently discharging rainfall infiltration interior underground water to the side slope superficial soil body.
The accompanying drawing explanation
Fig. 1 is the facade arrangement diagram of reorganization and expansion speedway soil-slope shallow-layer drainage system;
Fig. 1 is the sectional view of reorganization and expansion speedway soil-slope shallow-layer drainage system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, the underlying platform of side slope 1 is provided with gutter 6, be provided with the drainage hole 2 of interlaced arrangement on side slope 1, distance between drainage hole 2 is 3m, the drainage hole degree of depth is the 1.0m left and right, and the diameter of drainage hole 2 is 110mm, is provided with longitudinal drainage pipe 3 in drainage hole 2, the lower end of longitudinal drainage pipe 3 is communicated with transverse drain 4, and the length of the inner described transverse drain 4 arranged of side slopes at different levels increases from top to down successively.Longitudinal drainage pipe 3 and transverse drain 4 are the flexible porous bellows of high porosity, the transverse drain 4 of the high porosity of side slope 1 basecoat exceeds underlying platform 30cm, domatic vertical collecting gutter 7 and the horizontal collecting gutter 5 of being furnished with of side slope 1, vertically the section of collecting gutter 7 and horizontal collecting gutter 5 is 10cm * 10cm, the outlet of the transverse drain 4 of each high porosity is all docked with vertical collecting gutter 7 or horizontal collecting gutter 5, and vertically collecting gutter 7 and horizontal collecting gutter 5 are communicated with gutter 6.
Referring to Fig. 1 and Fig. 2, by depth of placement on side slope 1, the longitudinal drainage pipe 3 of little drainage hole 2 and side slope internal placement and transverse drain 4 fast, are efficiently discharged the rainwater of rainfall infiltration to side slope 1 shallow-layer, during the vertical collecting gutter 7 arranged on the surface of side slope 1 and the water body that laterally collecting gutter 5 flows out the longitudinal drainage pipe 3 of high porosity and transverse drain 4 are incorporated into gutter 6 and be discharged to outside side slope 1, prevent domatic being washed.
