Description
Technical field
The utility model belongs to environmental improvement, ecological restoration of mine technical field, and in particular to a kind of high steep side of hillock
Slope vegetation curing system.
Background technique
Gangue is the maximum industrial solid castoff of coal mine drainage amount, accounts for about 10-the 20% of raw coal output.The whole nation at present
There are thousands of hillocks not yet to administer, and annual also newly-increased about several hundred million new spoils of ton.Hillock does not only take up a large amount of soils, breaks
It is broken the ecoscape on periphery, while discharging a large amount of toxic and harmful gas, dust into atmosphere, and generates a large amount of leaching liquors.
Therefore the environmental ecology of hillock is administered, is had a great responsibility, arduous task.
As far as possible to store gangues to account for soil less, general hillock is designed to step-like, this has resulted in spoil more
The improvement region overwhelming majority is high abrupt slope, and many gradients have been more than 30 degree, and plagioclase is even more than 20 meters, the steep, slope surface with the gradient
Feature long, area is big, with a varied topography is not easy to irrigate and apply fertilizer.And hillock, due to soil depletion, slope surface is not easy to contain water, but
The maintenance for needing most water and fertilizer, it is more prominent particularly with this northern demand of drought.
It is higher for there is the improvement of the hillock of spontaneous fire danger to require, it quickly survives and grows with greater need for vegetation, formed
Protective layer.Main purpose is from rain erosion, lower part spoil is avoided to leak out, aoxidize, and prevents spontaneous fire.Therefore, cash
Vegetation maintenance is even more important in tor improvement.
Side slope formed in hillock improvement is different from agricultural, forestry, the maximum in landscape hillside fields, is exactly hillock side slope
Spoil under soil is easy spontaneous fire, and spontaneous fire necessarily causes top vegetation that can not survive, and this requires maintenances cannot
Destroy slope surface integrality, can neither soil erosion, erosions can not be formed, initiation spontaneous combus tion of waste heap；Riding track can not have excessively
Ponding, in order to avoid influence hillock stability of slope.For these reasons, existing hillock is administered mostly without maintenance facility, only
There is few part hillock to be equipped on large platform and pour water supplying pipe, water supply well, most hillocks are manually simple
Maintenance.Hillock is administered successfully in practice, especially vegetation survive, the luxuriant situation of vegetation it is seldom.To find out its cause, in addition to hillock side
Slope is more, the gradient is big, easily arid, do not contain the factors such as water, soil depletion and high temperature, spontaneous combustion and influence outer, conserving not in place is also one
A key factor.
Therefore how to solve above-mentioned problem, establish hillock high gradient slope vegetation curing system, to hillock vegetation growth,
Ecological environment treatment success is significant.

Extensively.Dropper belongs to the micro irrigation in part, is unsuitable for large area irrigation.Sprinkling irrigation is that pressure water is sent to sprinkling irrigation ground using special power
Section, can solve large area Irrigation Problems, relative to artificial watering, can avoid the destruction to sow grass seeds by duster substrate and seed layer, reduce and plant
The artificial mechanical injuries of quilt, the uniformity is high, can reduce slope runoff and local soil erosion.
Since sprinkling irrigation is that pressure (hydraulic) water is irrigated, discharge pressure is big, and water droplet is big, water yield is also larger, since slope surface earthing is relatively thin,
And mostly loose soil layer, water control is bad, runoff easily occurs, and quickly form groove, causes to corrode.When the gradient is steeper,
The entirety that may also result in substrate of sowing grass seeds by duster falls off.Simultaneously because the hillock gradient is larger, water is short in the slope surface residence time, water, fertilizer
It is lost more, utilization rate is low, and maintenance effect is not good enough.
Slight irrigation be it is by low pressure pipeline and the special fine-spraying belt of tail portion that water flow directive is aerial, fine-spraying belt is beaten using laser
Hole, precision is high, 0.5-1.2mm of aperture, fine and closely woven uniformly to form the spray effect as drizzle, not injure vegetation, uniformly wet
Nearby soil, the maintenance uniformity are high, it can be achieved that gross area irrigation for vegetation and vegetation root zone.Can make root system of plant keep be suitable for
Soil moisture, and be unlikely to generate deep percolation.More runoff will not be formed in slope surface, damaged.Have simultaneously and installs and uses
It is simple and convenient, it is easy mobile and keeping, feature at low cost.
In order to ensure hydraulic pressure is uniform, fine-spraying belt exists generally along contour lateral arrangement, but for high steep hillock
Following problem.(1) it since microspray irrigation is soft plastic tube, is difficult to fix on abrupt slope.(2) it is affected by gravity, upward slope direction
Unit area is small compared with direction of fall catchment area, is easy to cause slope surface watering uneven.(3) the best laying length of fine-spraying belt is 50-
70m, the hillock big for lateral length need to arrange several longitudinal branch pipes, increase the complexity and pipeline installation of pipe network
Difficulty, while vegetation is caused centainly to damage.Therefore conventional irrigation system is not suitable for the high abrupt slope vegetation maintenance of hillock.
