High-energy particle cutting rock breaking and tunneling device and working method thereof

Abstract

The application discloses a high kinetic energy particle cutting rock breaking and tunneling device, which comprises a base, a mechanical arm, a rock fissure and tunneling form real-time acquisition device, a rock breaking material supply system and a medium pressurizing device arranged on the base. The information collected by the structure surface trace line and tunneling form real-time acquisition device is transmitted to a control module. After the control module processes the information, a three-dimensional model of a tunnel excavation area is established, and rock fissure characteristics and trends are analyzed. The rock fissure cutting is preferentially planned. The high kinetic energy particles impact the rock in the tunnel area to be excavated, so that the rock generates a large instantaneous impact stress, and the impact point causes impact damage. The stress wave generated by the impact center point spreads outward, causing the rock to flow plastically and generate damage cracks and fissures. The high-speed and high-pressure abrasive and medium continuously impact the damage cracks and fissures, so that the cracks and fissures are expanded and connected, and the rock damage effect is further expanded.

Description

Technical Field

[0001] This invention belongs to the field of underground engineering construction technology, specifically relating to a high-energy particle cutting and rock-breaking tunneling device and its working method. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] In recent years, the number and scale of underground engineering projects in my country have gradually increased, and the projects are increasingly being constructed in extremely complex geological environments and harsh construction environments. Drill-and-blast method, as a major method for tunnel and underground engineering construction, has advantages over tunnel boring machine (TBM) methods, including lower initial investment, wider applicability to various geological conditions, less reliance on infrastructure, and flexible handling of adverse geological conditions. Therefore, it has gained widespread application and achieved significant economic and social benefits. However, explosive blasting methods have drawbacks such as easy disturbance to the surrounding rock, over-excavation and under-excavation problems, poor adaptability to complex and sensitive environments, and cumbersome approval processes, thus delaying tunnel construction. Meanwhile, emerging methods in recent years, such as static expanding agents, gas blasting, and mechanical splitting, all have certain limitations, such as unsuitability for hard rock, low efficiency, high cost, and significant noise interference, making it difficult to meet the requirements of safety, environmental friendliness, and quality in engineering projects. Therefore, there is an urgent need for a new tunnel boring method that is more flexible than TBM methods, safer and more environmentally friendly than explosive blasting methods, and more efficient than small TBM methods, responding to the national strategy of green development in infrastructure construction in the new era. Summary of the Invention

[0004] To overcome the above problems, this invention provides a high-energy particle cutting and rock-breaking tunneling device and its working method. This invention uses a real-time acquisition device for structural surface traces and tunneling morphology to transmit the acquired information to a control module. The control module processes the information, establishes a three-dimensional model of the tunnel excavation area, analyzes the characteristics and orientation of rock fissures, and prioritizes cutting along the rock fissures. High-energy particles impact the rock in the area to be excavated, generating significant instantaneous impact stress, causing impact damage at the impact point. Stress waves generated at the impact center propagate outwards, causing plastic flow in the rock and producing damage cracks and fissures. The continuous impact of high-speed, high-pressure abrasives and media on these damage cracks and fissures causes them to expand and connect, further amplifying the rock damage effect.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a high-energy particle cutting and rock-breaking tunneling device. The device includes a base, on which a robotic arm and a real-time acquisition device for rock fissures and tunneling morphology are mounted. A nozzle is provided at the end of the robotic arm. The nozzle is connected in sequence to a particle flow acceleration device, a rock-breaking material supply system, and a medium pressurization device through a first pipe. The rock-breaking material supply system includes an abrasive injection device and a particle injection device, which are connected through a second pipe.

[0007] The real-time rock fissure and tunneling morphology acquisition device transmits the acquired information to the control module. After processing the information, the control module controls the movement of the robotic arm so that the nozzle at the end of the robotic arm is aligned with the position and angle of rock cutting, controls the pressurization of the medium pressurization device, and controls the acceleration of the particle flow acceleration device.

[0008] A second aspect of the present invention provides a method for operating the above-mentioned high-kinetic-energy particle cutting and rock-breaking tunneling device:

[0009] Add abrasive to the abrasive injection device and particles to the particle injection device, then set aside for use;

[0010] The real-time rock fracture and tunneling morphology acquisition device collects information on the characteristics and orientation of rock fractures that need to be broken.

[0011] After processing the information, the control module establishes a three-dimensional model of the tunnel excavation area and determines the cutting path. It controls the movement of the robotic arm so that the nozzle at the end of the robotic arm is aligned with the rock cutting position and angle. At the same time, the control module controls the medium pressurization device to generate high-pressure, high-speed medium, which carries abrasive and particles into the first channel. The control module controls the particle flow acceleration device to accelerate the particles, so that the particles are ejected before the abrasive and continuously impact the rock to achieve particle cutting and rock breaking. Subsequently, the high-speed, high-pressure abrasive and medium continuously impact the cracks and fissures, expanding the rock cutting.

[0012] The beneficial effects of this invention are as follows:

[0013] (1) This invention uses a real-time acquisition device for structural surface traces and tunneling morphology to transmit the acquired information to a control module. After processing the information, the control module establishes a three-dimensional model of the tunnel excavation area, analyzes the characteristics and orientation of rock fissures, prioritizes cutting along rock fissures, and uses high-energy particles to impact the rock in the tunnel excavation area, causing large instantaneous impact stress and impact damage at the impact point. The stress wave generated at the impact center propagates outward, causing the rock to flow plastically and generate damage cracks and fissures; high-speed, high-pressure abrasives and media continuously impact the damage cracks and fissures, causing the fissures to expand and connect, further amplifying the rock damage effect.

[0014] (2) The rock-breaking method of the present invention automatically finds rock fissures and controls particles to prioritize impacting the rock fissure area with lower rock strength through a robotic arm, and then cuts the rock into blocks, which can save energy consumption and further improve rock-breaking efficiency.

[0015] (3) The cutting and rock breaking device and method of the present invention can eliminate the blasting disturbance of traditional tunnel blasting excavation, eliminate over-excavation and under-excavation, make the tunnel construction process uninterrupted, and significantly improve the tunnel construction efficiency.

[0016] (4) The particle recycling system of the present invention can use electromagnetic methods to adsorb particles after impacting rocks, so that the particles can be recycled, eliminating the pollution of soil by blasting residues and meeting the requirements of green environmental protection.
