Abstract

The invention provides a construction method of a non-blasting chain saw cutting machine. The construction method specifically comprises the following steps that a crawler walking mechanism and a moving mechanism of the chain saw cutting machine are used for driving a cutting chain saw to move to a proper position for cutting a tunnel face; the cutting chain saw carries out grid type cutting and fitting arc cutting on the tunnel face; and after cutting is completed, stone separation is carried out through a full saw cutting method or a hydraulic fracturing rock breaking method. According to the construction method, grid type cutting can be carried out on the tunnel face, and tunnel excavation and tunneling are carried out by adopting the hydraulic fracturing rock breaking method or the full saw cutting method to cut the section after cutting, so that the whole is broken up into parts, the excavation difficulty is reduced, the influence on a stratum is reduced, the labor intensity of workers is reduced, the over-excavation and under-excavation amount of the tunnel is reduced, the construction cost is reduced, and the like.

Description

technical field [0001] The present application relates to the technical field of tunnels, in particular to a non-explosive chainsaw cutting machine construction method. Background technique [0002] At present, with the continuous expansion of my country's engineering construction scale, my country's tunnel construction has ushered in unprecedented development opportunities, and my country has undoubtedly become a world tunnel power. At present, the main methods used in tunnel construction in hard rock formations in my country are TBM and drill-and-blast method. Among them, the drill-and-blast method has disadvantages such as complex procedures, slow progress, high labor intensity, and serious over- and under-excavation. It is difficult to achieve high efficiency, safety, and civilization. construction. TBM has the disadvantages of high equipment cost, single section form, complicated operation and so on. The existing hard rock tunnel construction method, such as applicatio...
