Tunnel Rapid Rock Breaking Excavation Support Intelligent Equipment

Abstract

The invention provides an intelligent equipment for rapid rock-breaking excavation and support for tunnels. The intelligent equipment for rapid rock-breaking excavation and support for tunnels includes a gantry frame, a laser rock-breaking device, an arch bolt installation device and a spraying device; The laser rock-breaking device includes a laser cutter and a laser rock-breaking mechanical arm, the laser cutter is connected to the gantry through the laser rock-breaking mechanical arm; the arch bolt installation device is used to clamp the arch, steel mesh or anchor body, the arch anchor installation device is connected with the gantry, so as to send the arch body, the steel mesh body or the anchor body to the Installation position: the spraying device is connected with the gantry frame, so as to spray the surrounding rock through the guide of the gantry frame. The rapid rock-breaking excavation and support intelligent equipment of the tunnel adopts laser rock-breaking, which reduces the impact of blasting construction on the surrounding environment and buildings, ensures the integrity of the surrounding rock, simplifies the construction process, and realizes full-section automatic without manual intervention. , thereby reducing construction risks and improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of tunnel equipment, in particular to intelligent equipment for rapid rock-breaking excavation and support for tunnels. Background technique [0002] Tunnel construction is still the most dangerous type of construction work. For example, tunnel excavators, tunnel erectors, and concrete sprayers work in a dark environment for a long time to perform heavy physical labor, with rock masses that may collapse and fall off at any time on their heads. There is still a work platform suspended several meters high under the feet. At the same time, the existence of blasting has aggravated the disturbance of the surrounding rock, such as collapse, rockfall, extrusion, and falling. [0003] The rock-breaking method of the tunnel in the prior art is the drill-and-blast method, which may cause irreversible damage to the surrounding rock; a large number of manual operations are used in the construction, and nearly 30 tunnel...

Problems solved by technology

At the same time, the existence of blasting has aggravated the disturbance of surrounding rocks, such as collapse, rockfall, extrusion, and falling.

[0003] The rock-breaking method of the tunnel in the prior art is the drill-and-blast method, which may cause irreversible damage to the surrounding rock; a large number of manual operations are used in the construction, and nearly 30 tunnel construction workers are required for one cycle. The distance between the tunnel and the roof is narrow and long, and the construction risk is extremely high; when the tunnel is constructed manually, since the various processes cannot be carried out at the same time, it is necessary to wait for the completion of the previous process before the effective connection can be realized, resulting in slow construction efficiency and restricting the current tunnel The construction speed is very high; based on TBM tool cutting or blasting-based cutting of the drill bit, the rock-breaking efficiency is very low when encountering hard surrounding rock, and the tool loss is very large; the mining method construction technology widely used in the construction process of tunnels in complex environments, Affected by blasting after tunnel excavation, the rock mass ruptures and becomes loose, and may collapse at any time, which may not only affect the construction process, threaten the safety of construction personnel, but also have a certain impact on the surrounding environment and buildings ; The rock mass excavated by traditional methods has become a solid waste, which has lost its use value, resulting in great waste and polluting the environment
