Abstract

The invention relates to a method for greening a quartz high-steep slope surface in an arid and rainless area, which belongs to the field of high-steep slope greening, and is used for increasing the aperture to 300mm in an area with less rainfall, but because the quartz is high in hardness and crisp in property, a drilling machine is seriously abraded, the cost of a direct practical 300mm aperture drilling machine is high, and the construction difficulty is higher.

Description

A kind of high steep slope greening method of drought area quartzite

Technical field

The invention belongs to high gradient slopes to answer green field, green more particularly to a kind of high steep slope of drought area quartzite Change method.

Background technique

High steep quartzy rock feature are as follows: greyish white, sallow, flesh pink, part are aubergine, middle thickness~thick-layer shape, fine and close, Hard, folder lamelliform cinerous, aubergine slate, local slate contain Silty sandstone, and joint plane has sericitization phenomenon, constructs Breccia development.High steep rock slope always is that geological disaster is administered and the difficult point of greening, improvement area's quartzite respective location exist Small crack and joint, high steep rock slope always are the difficult point that geological disaster is administered and afforested, appeared in limestone side in recent years The way of slope punching backfill planting soil greening, achieves good results, due to its lithologic character, in rock moisture self-restraint compared with It is few, it is main after greening still to lean on natural rainfall and rock fracture water, but in drought area, rock and aqueous seldom area Domain, conventional 150mm bore are difficult to the survival rate for guaranteeing to plant green plant.

Summary of the invention

The technical problem to be solved in the present invention is that a kind of high steep slope greening method of drought area quartzite is provided, The method is in the less region hole diameter enlargement of rainfall, to 300mm, but since quartzite hardness is big, property is crisp, to drilling machine Serious wear, and directly the practical aperture 300mm rig cost is high, difficulty of construction is bigger, and the method for the present invention utilizes small-bore drilling machine It is triangular in shape to beat three times, 300mm borehole is completed, at low cost, the time is short, and difficulty of construction reduces significantly, and advantageously In the growth of plant.

The invention adopts the following technical scheme:

A kind of high steep slope greening method of drought area quartzite, the method are specific as follows:

1) it is crept into slope surface with bore 100mm drilling horizontal.

2) brill in second aperture 100mm is crept at first bore edges 80-90mm of lower left distance in first hole First bore edges 80-90mm of central point distance in hole namely second hole；

3) in the right drilling third at the edge 80-90mm in first hole of distance and second hole respectively in second hole The central point in hole, bit diameter 100mm namely third hole respectively the edge in first hole of distance and second hole away from It from equal, and is 80-90mm, it is in equilateral triangle after the line of centres in three holes；

4) the disturbance natural expansion generated in drilling process the extension in each hole, makes three hole connection, and close to circle, Backfill planting soil is simultaneously afforested.

Due to generating tiny crack in drill process, the drilling hole that is generated after three holes are in equilateral triangle and slightly overlapping Diameter is big up to 300mm or more.

The present invention compared with prior art the utility model has the advantages that

The present invention by that, using greening aperture is expanded, can not store rainwater to high steep rock to solve high steep rock crevice less The problem of, simultaneously because the characteristic of high steep rock, hardness is big, and brittleness is high, expansion aperture is directly carried out on quartzy rock, to brill Head abrasion is big, and be easy to cause scar avalanche, this is also the major issue for restricting high steep rock greening always, and the method for the present invention is logical It crosses and replaces a 300mm drilling using three 100mm bores triangular in shape, due to the shock effect in drilling process, rock More more broken than one-step pore-creating, minor fracture suitably increases, and can provide more water sources for the plant later period and be conserved, more Added with the growth for being conducive to plant.

It is at low cost, the time is short and difficulty of construction is small after the method for the present invention replaces bore 300mm with 100mm bore drilling machine 100mm bore drilling machine price is much smaller than the drilling of bore 300mm, needs first to set up scaffold on rock mass in work progress, It is locally fixed temporarily drilling machine on scaffold to be crept into, back pressure is much smaller than bore 300mm in 100mm bore borer drilling procedure Drilling machine, the fixed relatively easy and set time is short, and difficulty of construction is small to also save a large amount of time.

Specific embodiment

Technical solution of the present invention is further explained below by embodiment combination attached drawing, but protection of the invention Range is not limited in any form by embodiment.

Embodiment 1

A kind of high steep slope greening method of drought area quartzite, as shown in Figure 1.The method is specific as follows:

1) it is crept into slope surface with bore 100mm drilling horizontal, as shown in Figure 2.

2) drilling in second aperture 100mm is crept at first bore edges 80mm of lower left distance in first hole, Namely first bore edges 80mm of the central point distance in second hole；

3) third hole is crept at the edge 80mm in first hole of distance and second hole respectively on the right in second hole, Bit diameter is 100mm namely the Edge Distance in the central point in third hole first hole and second hole of distance respectively It is equal, and be 80mm, it is in equilateral triangle after the line of centres in three holes, as shown in Figure 3；

4) the disturbance natural expansion generated in drilling process the extension in each hole, makes three hole connection, and close to circle, Backfill planting soil is simultaneously afforested, as shown in Figure 4.

Embodiment 2

A kind of high steep slope greening method of drought area quartzite, the method are specific as follows:

1) it is crept into slope surface with bore 100mm drilling horizontal.

2) drilling in second aperture 100mm is crept at first bore edges 90mm of lower left distance in first hole, Namely first bore edges 90mm of the central point distance in second hole；

3) third hole is crept at the edge 90mm in first hole of distance and second hole respectively on the right in second hole, Bit diameter is 100mm namely the Edge Distance in the central point in third hole first hole and second hole of distance respectively It is equal, and be 90mm, it is in equilateral triangle after the line of centres in three holes；

4) the disturbance natural expansion generated in drilling process the extension in each hole, makes three hole connection, and close to circle, Backfill planting soil is simultaneously afforested.

Afforestation is carried out to high steep slope rock using above-described embodiment method, administers area's Multi-year average precipitation 550mm or so, annual mean ground temperature is 1479.95mm since 2014.Improvement area's rock lithology is quartzite, and hardness is big, compared with Crisp, Pu Shi rock consolidating coefficient f is 20, larger to the abrasion of drill bit, and is capable of the 300mm of horizontal drilling currently on the market Drilling machine it is less and expensive, difficulty of construction is big, long in time limit, and in order to improve this situation, we are used by test of many times The each drilling of the electronic down-the-hole drill of the KQD100A drilling triangular in shape for making a call to three holes formation bore 300mm is instead of bore 300mm's Water drilling puncher, the drilling machine are suitble to the rock that f is 6-20 to punch, once creep into 1000mm, this depth of pore forming 750m is primary to bore Into can reach depth requirements, this is suitble to drill work.The method of the present invention is more advantageous to the survival of green plant, reduces costs, Reduce the duration, reduce difficulty of construction, achieves extraordinary effect.
