Abstract
The invention discloses a submerged flexible draining structure on a road side slope. Water-proof geotextiles (1) are paved on the two sides and the bottom of a drain ditch; a water-permeating geotextile (7) is paved on the upper part of one side, close to the side slope, of the drain ditch; a soft water-permeating pipe (2) is arranged on and a breakstone layer (3) is filled in the lower part of the drain ditch on which the water-proof geotextiles (1) are paved; and a sheet stone layer (4) is filled on the upper part of the breakstone layer (3) in the drain ditch. The submerged flexible draining structure is high in deformation resistance and still has the draining function when the surface soil body of the side slope (such as an expanded side slope and the like) is expanded and deformed.
Description
Technical field
The present invention relates to a kind of discharge structure of slope of highway, particularly relate to a kind of dark formula flexible water drainage structure of slope of highway.
Background technology
The ground bare land that commute washes away be in the take place frequently highway excavation slope in district of heavy rain, for preventing rainfall to excavating domatic washing away, catchwater need be set, on plain stage of slope, the platform gutter need be set on the top, excavation slope slope that charge for remittance is arranged.It often is to build the rigidity open drain that forms by laying bricks or stones by mortar flag stone or concrete mortar that said catchwater and platform edges are linked up.Excavation slope for expansive soil highway section and highway section, landslide; Because domatic distortion can cause the cracking destruction of rigid drainage works and drain function to lose efficacy; Thereby make face of land rainfall from the crack, infiltrate sloping body, cause the shallow top layer of side slope to meet the water humidifying and form slope wash and part sliding destruction of collapsing.
Summary of the invention
It is strong that technical problem to be solved by this invention provides a kind of non-deformability, when there is swell-shrinking deformation in the slope table layer soil body, still can bring into play the dark formula flexible water drainage structure of the slope of highway of drain function.
In order to solve the problems of the technologies described above; The dark formula flexible water drainage structure of the slope of highway that the present invention provides; Both sides and bottom of trench in the gutter are equipped with the waterproof geotextiles; Permeable geotextile laying is at a upper lateral part on the slope of keeping to the side in gutter, and the bottom in the gutter that is equipped with described waterproof geotextiles is placed with flexible porous tube and is filled with macadam, and ragstone layer has been filled on the top of the described macadam in the gutter.
The top of described ragstone layer is formed with the cut slope platform.
Adopt the dark formula flexible water drainage structure of the slope of highway of technique scheme, through laying the waterproof geotextiles; Permeable geotextiles, flexible porous tube, macadam and ragstone layer; Can realize that surface drainage in the slope project, the soil body draining of domatic top layer, platform resistance to deformation and antiscour, damaged or destroyed by flood destroy, be to integrate the slope drainage works that platform draining and the anti-antiscour of platform, damaged or destroyed by flood destroy.
In sum, the present invention is that a kind of non-deformability is strong, and (like expansive soil slope) still can be brought into play the dark formula flexible water drainage structure of the slope of highway of drain function when there is swell-shrinking deformation in the slope table layer soil body.
Description of drawings
Fig. 1 is dark formula flexible water drainage groove structure figure.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Referring to Fig. 1; Both sides and bottom of trench in the gutter are equipped with waterproof geotextiles 1; Permeable geotextiles 7 is laid on a upper lateral part on the slope 6 of keeping to the side in gutter; Bottom in the gutter that is equipped with waterproof geotextiles 1 is placed with flexible porous tube 2 and is filled with macadam 3, and ragstone layer 4 has been filled on the top of the macadam 3 in the gutter, and the top of ragstone layer 4 is formed with cut slope platform 5.
Referring to Fig. 1; The present invention is through laying waterproof geotextiles 1, permeable geotextiles 7, flexible porous tube 2, macadam 3 and ragstone layer 4; Can realize that surface drainage in the slope project, the soil body draining of domatic top layer, platform resistance to deformation and antiscour, damaged or destroyed by flood destroy, be to integrate the slope drainage works that platform draining and the anti-antiscour of platform, damaged or destroyed by flood destroy.
Referring to Fig. 1; Platform gutter and sloping top catchwater commonly used are at present normally built the rigidity open drain that forms by laying bricks or stones by mortar flag stone or concrete mortar; When side slope is the expansive soil geological conditions; The breathing effect meeting of expansive soil causes the discharge structure deposits yields cracking destruction of being built by laying bricks or stones by mortar flag stone or concrete mortar, thereby drain function was lost efficacy.The dark formula flexible water drainage structure of slope of highway provided by the invention; Can come together in the perched water in the platform upper slope toe place top layer soil body through permeable geotextiles 7 drainages; Can play the effect of the eliminating surface water of platform gutter again; Simultaneously, dark formula flexible water drainage ditch has stronger resistance to deformation damage capability, and makes whole flat double as discharge structure thing through ragstone layer 4 is set at platform surface; Thereby make platform both have common offloading functions, played the multiple action of permeable, antiscour and damaged or destroyed by flood again.Dark formula flexible water drainage ditch also has the advantage of easy construction, is particularly useful for expansive soil and similar geological conditions thereof.
Claims (2)
