Technical field
The invention belongs to technical field of drainage, and in particular to a kind of semi-flexible Quick drainage system administered applied to hillock
System.
Background technology
Gangue is the maximum industrial solid castoff of coal mine drainage amount, accounts for about the 10~20% of raw coal output.The whole nation at present
There are thousands of hillocks not yet to administer, also increases several hundred million tons of spoils newly every year.Hillock does not only take up a large amount of soils, destroys periphery
Ecoscape, while a large amount of toxic and harmful gas, dust are discharged into air, and generate a large amount of leaching liquors.Therefore to cash
The ecological environment treatment of Stone Mountain, has a great responsibility, arduous task.
The conventional method that hillock is administered：It cuts slope arrangement → earthing → and constructs drainage ditch → vegetation.Due to hillock from
Characteristic is fired, drainage ditch apolegamy and setting therein are most important to hillock improvement, directly influence the success or failure of hillock improvement.
Traditional hillock drainage ditch generally uses concrete or stone masonry to construct, and is commonly called as rigid water channel, the water channel is most
Big defect is not anti-settling, the i.e. differential settlement of hillock, easily water channel is caused to be broken, not only influences the normal of drainage system
Operation, and lead to rainwater infiltration, channel of leaking out is formed, leads to hillock spontaneous fire, or even cause just in the spoil of spontaneous combustion
It explodes on mountain.
The shortcomings that for hillock rigid drainage canal and deficiency, patent CN202672119U《Gangue flexible water drainage canal》It is public
A kind of flexible water drainage canal has been opened, that is, has excavated trapezoidal ditch, loess formation has been covered on ditch side and bottom surface, geotechnique is laid on loess formation

Combustion.
2. a large amount of rainwater directly rush at slope surface and riding track, soil erosion is caused, or even vegetation on slope of destroying by rush of water.
3. rainwater infiltration generates percolate, polluted underground water and soil to spoil area.
4. the soil on riding track impregnates for a long time, easily causes landslide, collapses and settle, then drainage system is caused more
Havoc, vicious circle.
5. the rainwater on riding track cannot flow directly into water channel, riding track is gently then impregnated, it is heavy then wash away slope surface.
