The road construction method includes the steps of: firstly, clearing the soil materials below the road pressure surface; then, mixing the cleared soil materials with sand and performing stirring; and finally, refilling the road with the mixed and stirred mixture, and spreading a wearing layer on the top, and then conducting maintenance work. According to the road construction method for strip mine, sand is mixed in a single soil material to change the road material structure and enhance the material hardness, the road transportation quality is enhanced, and the integrated road bears more enormous upper pressure in the truck transportation process. And the difficulty that existing road construction methods are difficult to meet normal transportation operation of large mechanical equipment in strip mine can be overcome.

Description

The constructing road method of opencut
Technical field
The present invention relates to opencast mining field, particularly a kind of constructing road method of opencut.
Background technology
At present, domestic large, medium and small opencut main production program comprises digging coal petrography, transport and disposing three phases, and part opencut comprises explosion.Under normal condition, transport routes (soil road) are struck off by blade machine process and just can travel for vehicle.
But along with the maximization day by day of mine transportation equipment, truck carries goods weight and day by day strengthens, and therefore road is out of shape gradually because reaching the bearing pressure limit, finally causes road destroyed, and truck transport efficiency straight line declines.This situation is especially serious in geology softly mine.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of constructing road method of opencut of simple and reasonable steps, the constructing road method of this opencut changes road materials structure by being mixed into sandstone in single soil property material, improving material hardness, improve road transport quality, make integrated road in truck transport process bear huger upper pressure.Overcome the difficulty that the existing method of repairing the roads is difficult to meet the operation of opencut heavy mechanical equipment normal transport.
For achieving the above object, the invention provides the constructing road method of opencut, comprise the following steps: first, clear out the soil property material of below road pressure-bearing surface; Then, the soil property material cleared out and sandstone are carried out mixing, stirring; Finally, the mixed material after mix and blend is filled out back in road again, and at its top spreading wearing layer, then carry out health work.
Preferably, in technique scheme, the soil property material thickness cleared out below road pressure-bearing surface is two meters.
Preferably, in technique scheme, the soil property material cleared out and sandstone are undertaken mixing, stirring by the volume ratio of 2:1.
Preferably, in technique scheme, in the middle of the road surface adopting this constructing road method to build, high both sides are low.
Compared with prior art, the present invention has following beneficial effect: the constructing road method of this opencut changes road materials structure by being mixed into sandstone in single soil property material, improving material hardness, improve road transport quality, make integrated road in truck transport process bear huger upper pressure.Overcome the difficulty that the existing method of repairing the roads is difficult to meet the operation of opencut heavy mechanical equipment normal transport.

Fig. 2 is the road longitudinal section that the constructing road method of opencut of the present invention is built.
Fig. 3 is the path formation longitudinal section that the constructing road method of opencut of the present invention is built.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
Pass through to change the single soil property material structure of road according to the constructing road method of the opencut of the specific embodiment of the invention, sandstone are mixed in material, improving material hardness, concrete experience in incorporation engineering, carries out proportion expression and refers and synthesizes, finally be modulated into high strength material and can combine together, realize integrated road in truck transport process and bear huger upper pressure, improve traffic condition, with low cost, structure is simple, mine hoisting remarkable benefit.
The constructing road method of this opencut comprises the following steps:
First, the soil property material in road pressure-bearing surface two meters of thickness is cleared out;
In road longitudinal section as shown in Figure 1, the thickness that road bears equipment pressure is generally 1.5-2 meters, therefore soil property material 1 in truck contact surface two meters of thickness is needed all to release, to change the single soil property material structure of road, carry out improving material hardness, realize integrated road in truck transport process and bear huger upper pressure, improve traffic condition.
Then, the soil property material cleared out and sandstone are undertaken mixing, stirring by the volume ratio of 2:1;
Note, in soil property material and sandstone whipping process, can not moisture be mixed, make material become drying by constantly stirring, condensation is block.
As shown in Figure 2, finally, the mixed material 2 after mix and blend is filled out back in road again, and at its top spreading wearing layer 3, then carry out health work.
The time of health work remains on more than two days, realizes material in two days and continues inner fusion, solidifies, and final height of formation solidification, bears high stress.
In addition, when road builds up, different gaps is there is between material, although can solidify in health process, condense, but after the going and back running and roll of heavy load truck, the gap of storeroom can become less, can obviously diminish before the volume of material compares and rolls, road surface inherently there is much low-lying, scarce material sections, in order to save constructing road cost, " playing drum " type road surface that this opencut road takes middle high both sides low, can avoid producing situation low-lying, in short supply because truck rolls in the use procedure in the early stage of newly-built road like this.
As shown in Figure 3, in newly-built road occupation process, because of repeatedly rolling of heavy load truck, often can there is uneven section in road surface, this section not only can affect driver driving truck, but also can accelerate the parts consumption of truck, work more economically, efficiently to make truck, blade machine 4 must carry out smooth to out-of-flatness section often, and the moment keeps road surface to be in flat condition, is convenient to travelling truck.
To sum up, the constructing road method of this opencut changes road materials structure by being mixed into sandstone in single soil property material, and improving material hardness, improves road transport quality, makes integrated road in truck transport process bear huger upper pressure.Overcome the difficulty that the existing method of repairing the roads is difficult to meet the operation of opencut heavy mechanical equipment normal transport.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
