Abstract

A method for applying a wire saw to underground rock engineering through in-hole anchor guiders comprises the following steps: S1, boring four holes in the rock body; S2, anchoring the in-hole anchor guiders in the preset positions in the holes respectively, so that a diamond beaded rope can enter from one hole, bypasses a guide pulley of the anchor guider in the hole, comes out from the hole, enters from another hole, bypasses a guide pulley of the anchor guider the hole, comes out from the hole, the diamond beaded rope returns to a fly wheel of the wire saw to form a loop, the wire saw is started to cut one face of the rock, and other faces are cut through the same method; S3, once cutting of all the five faces are finished, a slow type windlass L is used for pulling out the stone, and the operation of opening a hole for rock is completed.

Description

Make the rope saw be used for the method for subsurface rock engineering by anchoring guider in the hole

Technical field

The invention belongs to subsurface rock engineering scope, relate to and a kind ofly make the rope saw be used for the method for subsurface rock engineering by anchoring guider in the hole.

Background technology

In the subsurface rock engineering construction in modern times, more general method is to use explosive to carry out blast working, and the problem of concentrated reflection is that its difficulty of construction is large, rock mass is damaged poor stability; Particularly in the strip mining transformation method of stone digging, the destruction that the fund input that it is huge is used for peeling off of the destruction of surface vegetation and weathered layer and environment is caused is also in the urgent need to being substituted by the method for the stone hole mining of more scientific environmental protection.Based on above problem and shortage, we have invented and have a kind ofly made the rope saw be used for the construction method of subsurface rock engineering by anchoring guider in the hole, the subsurface rock engineering roadblock such as solve that existing tunnelling, underground engineering, hole, mine are adopted.

Summary of the invention

Technical problem to be solved by this invention provides and a kind ofly makes the rope saw be used for the construction method of subsurface rock engineering by anchoring guider in the hole, carries out sawing at the rock mass that only has a scope of freedom (a, b, c, d face).

The present invention adopts following technical scheme, comprises the steps:

First bore A, B, C, four holes of D at the rock mass facade of needs excavation and divide and be clipped to E, F, G, H point, as shown in Figure 2.

The anchoring guider is anchored at respectively four desired locations in the hole in the hole of diamond bead string rope with having gone here and there, and as shown in Figure 3, diamond bead string rope is set out by the flywheel of rope saw, enters from the A hole, walk around this hole in anchoring guider directive wheel afterwards from the A hole out.Enter from the C hole again, walk around behind the directive wheel of the anchoring guider in this hole from the C hole out.The flywheel of getting back to the rope saw forms the loop.Start rope saw sawing A, E, C, G face (left surface), the part of cutting among the figure shows (N) with oblique dotted line, because the diamond saw rope has plasticity, sawing blind area (M) unavoidably can occur.

According to the same manner sawing B, F, D, H face (right flank), as shown in Figure 3.

According to the same manner sawing C, G, D, H face (bottom surface), as shown in Figure 4.

Put into from A, B hole respectively having gone here and there in the hole of diamond bead string rope the anchoring guider, be anchored at desired location.With the flywheel of diamond bead string rope from the rope saw, enter in the hole through the A point, walk around the directive wheel e point of the anchoring guider in this hole, to the g point again to the h point, then walk around f point directive wheel, the flywheel that arrives the rope saw through B point leadout hole outward forms the loop, starts rope saw sawing e, f, g, h face (back side), as shown in Figure 5.

Adopt and same method sawing C, G, D, the H face (end face) in sawing bottom surface, as shown in Figure 6.

After five faces all cut, use slow-motion hoist (L), stone is pulled out, finish sawing.As shown in Figure 7.

Use this sawing method cutting two sides and top, bottom surface, adopt the sawing mode with respect to dew and be called the traditional method of indicating the pronunciation of a Chinese character.Back side cutting is called the back of the body and cuts.This is a kind of static sawing mode of full rope saw, can carry out the subsurface rock engineering construction of especially big sectional plane.Be fit to and the tunnel, heavy in section underground engineering, stone hole mining.Relatively to have a cost low for traditional approach, and progress is fast, and is safe, do not damage rock mass structure, do not peel off the advantage of surface vegetation.

The specific embodiment

Bore A, B, C, four holes of D at the rock mass facade of needs excavations and divide and be clipped to E, F, G, H point, as shown in Figure 2.

The anchoring guider is anchored at respectively four desired locations in the hole in the hole of diamond bead string rope with having gone here and there, and as shown in Figure 3, diamond bead string rope is set out by the flywheel of rope saw and enters from the A hole, walk around this hole in anchoring guider directive wheel afterwards from the A hole out.Enter from the C hole again, walk around behind the directive wheel of the anchoring guider in this hole from the C hole out.The flywheel of getting back to the rope saw forms the loop.Start rope saw sawing A, E, C, G face (left surface is defined as the traditional method of indicating the pronunciation of a Chinese character), according to the same manner difference sawing right flank (see figure 3), bottom surface (see figure 4) and end face (see figure 6).

Put into from A, B hole respectively having gone here and there in the hole of diamond bead string rope the anchoring guider, be anchored at desired location.With the flywheel of diamond bead string rope from the rope saw, enter in the hole through the A point, walk around the directive wheel e point of the anchoring guider in this hole, to the g point again to the h point, then walk around f point directive wheel, the flywheel that arrives the rope saw through B point leadout hole outward forms the loop, starts rope saw sawing e, f, g, the h face (back side, being defined as the back of the body cuts), as shown in Figure 5.

After five faces all cut, use slow-motion hoist (L), stone is pulled out.As shown in Figure 7.
