Abstract

Provided is a cannon-free mechanical tunneling technology for hard rock. The technology specifically includes the steps that firstly, punching positions are arranged; secondly, punching is performed according to the preset positions; thirdly, cleaving is performed; fourthly, tunneling is performed; fifthly the operation is repeated. According to the technology, explosives are not used at all. The cannon-free mechanical tunneling technology for hard rock is used for replacing a traditional cannon tunneling technology, work efficiency is greatly improved, the safety coefficient is greatly increased, and the requirements of safe and efficient production are met; the mechanical level of tunneling operation is high, the number of personnel on a work face is substantially reduced, and labor intensity of workers is relieved; rock joints are damaged through a cleaving device, the cutting power of a tunneling machine is reduced, energy consumption is lower, and the problem that hard rock is difficult to cut is eradicated; cutting tooth abrasion is weakened, the replacement period of parts easy to damage and consume is prolonged, and production efficiency is improved.

Description

A kind of hard rock is without big gun mechanical drivage technique

Technical field

The present invention relates to a kind of piercing technique of rock, particularly a kind of a kind of hard rock being applicable to high rigidity stone drifting operation is without big gun mechanical drivage technique.

Background technology

At present, all kinds of tunnelling of China generally adopts big gun to dig method, and it utilizes hammer drill perforating, and manual charging has blown out driving task, and the method technique is comparatively ripe, is still the main form of construction work of domestic each tunnelling so far.But the method Mechanization Level is low, hand labor intensity is large, there is serious potential safety hazard, can not adapt to the use that should control now explosive, again efficiently, the production requirement of safety.

Summary of the invention

The present invention is low in order to solve current big gun tunneling process safety factor, hand labor intensity is large, ineffective problem, provide a kind of hard rock without big gun mechanical drivage technique, this technique is completely without explosive, have employed hard rock without big gun mechanical drivage technology generations for traditional big gun tunneling process, operating efficiency and safety factor are greatly improved, and meet the requirement of safe and efficient production; Excavation operation Mechanization Level is high, and work plane personnel input amount significantly reduces and workman's amount of labour is reduced; Utilize cleaving device to destroy rock joint, reduce the cutting power of development machine, energy consumption is lower, and has stopped the problem that solid rock is difficult to cut; Pick wearing and tearing weaken, and the rapid wear attrition component replacement cycle increases, and production efficiency is significantly improved.

The present invention solves the concrete technical scheme that its technical problem adopts:

A kind of hard rock, without big gun mechanical drivage technique, comprises the steps:

The first step: arrange punch position, design, hardness big hole pitch is little according to the situation such as formation hardness, bedding to punch position, hardness aperture pitch is large, pitch of holes rests between 0.5 ~ 1.3 meter.

Second step: by presetting position punching, treating that digging laneway section creeps into splitting hole by the orientation pre-set, described splitting hole internal diameter is as the criterion with the specification of splitting device.

3rd step: splitting, inserts splitting device respectively in the splitting hole of having bored and carries out cleavage operations, makes to treat that some crackles appear in digging laneway section, for follow-up driving is ready.

4th step: driving, after cleavage operations completes, the inner joint of solid rock is destroyed, and manipulation cutting part of heading machine utilizes rock crackle forming to carry out excavation operation.

5th step: repeat above-mentioned operation, the rock in cleaning tunneling process under cut, moves forward equipment and carries out next round excavation operation.

In preferred technical scheme, the punch position described in the first step specifically designs punch position according to the physical property of cross-section shape of roadway, rock bedding, and hardness big hole pitch is little, hardness aperture pitch large, and pitch of holes rests between 0.5 ~ 1.3 meter.

In preferred technical scheme, punch described in second step, employing be hydraulic gate or hydraulic drill ring.

In preferred technical scheme, splitting described in the 3rd step, employing be expansion agent or hydraulic splitting equipment.

In preferred technical scheme, rock described in the 5th step is cleared up, and is by shovel board of development machine portion rock collected Department of Transportation and transport to scope of operation rear, then transports tunnel by elevating conveyor and Moveable belt transporter.

The beneficial effect that the present invention has is: this technique is completely without explosive, and have employed hard rock without big gun mechanical drivage technology generations for traditional big gun tunneling process, operating efficiency and safety factor are greatly improved, and meet the requirement of safe and efficient production; Excavation operation Mechanization Level is high, and work plane personnel input amount significantly reduces and workman's amount of labour is reduced; Utilize cleaving device to destroy rock joint, reduce the cutting power of development machine, energy consumption is lower, and has stopped the problem that solid rock is difficult to cut; Pick wearing and tearing weaken, and the rapid wear attrition component replacement cycle increases, and production efficiency is improved.

detailed description of the invention:

Below in conjunction with accompanying drawing the present invention done and further explain.

As depicted in figs. 1 and 2, a kind of hard rock that this detailed description of the invention provides, without big gun mechanical drivage technique, comprises the steps:

The first step: arrange punch position, design, hardness big hole pitch is little according to the situation such as formation hardness, bedding to punch position, hardness aperture pitch is large, pitch of holes rests between 0.5 ~ 1.3 meter.

Second step: by presetting position punching, hydraulic gate or hydraulic drill ring 1 is adopted to treat that digging laneway section creeps into splitting hole by the orientation pre-set, the drilling equipment that present embodiment adopts is hydraulic drill ring 1, and described splitting hole internal diameter is as the criterion with the specification of splitting device.

3rd step: splitting, inserts expansion agent or hydraulic splitting 2 equipment in the splitting hole of having bored and carries out cleavage operations, and present embodiment adopts hydraulic splitting rod 2 to carry out cleavage operations, makes to treat that some crackles appear in digging laneway section, for follow-up driving is ready.

4th step: driving, after cleavage operations completes, the inner joint of solid rock is destroyed, and the cutting units on manipulation development machine 3 utilizes rock crackle forming to carry out excavation operation.

5th step: repeat above-mentioned operation, collects Department of Transportation by the shovel board portion on development machine 3 by rock and transports to scope of operation rear, then by elevating conveyor and Moveable belt transporter, rock being transported tunnel, moved forward by equipment and carry out next round excavation operation.
