Problems solved by technology

Rock fragmentation means that its utilization rate will be greatly reduced, and the treatment of crushed stone will also increase the project cost; the traditional blasting method has problems such as large vibration, crushed stone splashing, and dust pollution, which seriously affect the safety of construction personnel and are not conducive to environmental protection; Removal of drilling and other equipment before blasting affects construction efficiency
In addition, at present, there is little research and development on thermal melting rock breaking devices in tunnels, and there is no complete set of tunnel hard rock integrity excavation devices

Abstract

The invention discloses a tunnel full-section hot-melting rock breaking device and method. The tunnel full-section hot-melting rock breaking device comprises a hot-melting generating device and a crawler-type trolley, wherein the hot-melting generating device comprises a plurality of heating pipes which are horizontally arranged, the heating pipes are fixed to a control panel, the control panel is connected with a hydraulic propelling device, and the control panel can be pushed by the hydraulic propelling device so as to drive the heating pipes to move horizontally; and a fixed frame is arranged on the top of the crawler-type trolley, a wheel axle type lifting device is arranged on the side part of the fixed frame, and the hydraulic propelling device is connected with the wheel axle type lifting device so as to drive the hot-melting generating device to move up and down.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a full-section thermal melting rock-breaking device and method of a tunnel. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the construction of high-speed railways in mountainous areas, the construction of tunnels often accounts for the largest proportion of the entire project, so the tunnel excavation speed and construction quality directly affect the social and economic benefits brought by high-speed railways. [0004] At present, in the process of tunnel excavation, blasting is usually used in areas with good geological conditions. The blasting is accompanied by the crushing of a large amount of rock to separate it from the parent rock. Rock fragmentation means that its utilization rate will be greatly red...
