Problems solved by technology

[0005] In general, traditional equipment mostly has the following problems in the excavation process of hard rock roadways (tunnels): 1) The non-continuous excavation method of blasting will cause strong disturbance to the roadway (tunnel) surrounding rock and ground surface, and the occurrence of blasting It will cause potential safety hazards and generate harmful gases, threatening the safety of the staff; 2) After the explosion occurs, long-term ventilation is required to discharge harmful gases, which

Embodiment Construction

[0030] After the hydraulic fracturing is completed, the water injection pipe is disconnected, and the operator re-enters the drilling control console to carry out the excavation of the roadheader. The excavation route of the roadheader is that the cutting part of the roadheader enters the knife from one end of the bottom of the roadway (tunnel) to perform horizontal cutting, and after the pick cuts to the other end of the roadway (tunnel) in the horizontal direction, it moves upward along the direction perpendicular to the floor After cutting a certain distance, continue to cut horizontally. At this cutting depth, continue to complete the above operations in a cycle until the entire cutting depth is excavated. After the excavation is completed, continue the next section of cutting until the excavation reaches hydraulic fracturing. The bounds of the range.

[0031] Due to the integration of three machines, after the roadheader advances to the end of fracturing, the above operat...

Abstract

The invention discloses drilling-pressing-tunneling integrated hard rock tunneling equipment, relates to the field of hard rock roadway (tunnel) tunneling, and can reduce potential safety hazards of tunneling work to the minimum and greatly improve the tunneling efficiency. The hard rock tunneling equipment comprises a tunneling machine, a drilling machine system and a hydraulic fracturing system, wherein the drilling machine system and the hydraulic fracturing system are mounted on the tunneling machine; the drilling machine system comprises a drilling machine, a drilling machine mounting table, a drilling arm, a sliding rail and a base; the sliding rail is connected to a rack of the heading machine; the hydraulic fracturing system comprises a water tank, a high-pressure pump, a pressure gauge, a water pressure monitor, a high-pressure pipe and a hole packer, and the high-pressure pump is fixedly connected to a rack of the heading machine. Not only is harmful gas not required to be discharged, but also integrated equipment is not influenced by working face space, so that the maneuverability of a drilling machine and hydraulic fracturing equipment is remarkably improved, and the purpose of improving the working efficiency of tunneling engineering is finally achieved.

Description

technical field [0001] The invention relates to the field of hard rock roadway (tunnel) excavation, in particular to a hard rock roadway (tunnel) roadway excavation equipment which adopts the integration of drilling pressure and excavation. Background technique [0002] At present, the drilling and blasting method is still the main method for tunneling in hard rock (tunnel). This tunneling process requires a lot of labor and construction time, has low safety, and affects the progress of tunneling. Usually, the drilling and blasting method is adopted on the premise that the excavation of the roadheader is difficult to realize, and the tunneling method of the hard rock roadway (tunnel) meets the construction conditions of the drilling and blasting method. However, due to the various disadvantages of the drill and blast method, a new method that uses hydraulic fracturing combined with roadheader excavation has emerged. By drilling holes in hard rock roadways (tunnels) and inje...
