Convenient construction method for tunnel structure

Abstract

The invention discloses a convenient construction method for a tunnel structure. The construction method is characterized by including the steps of: step a, blasting the mine on a place where a tunnel is excavated, laying a horizontal guide rail on the exploded place, and excavating with an excavating device of the horizontal guide rail; step b, blasting while excavating to excavate gradually; step c, using a boring device on the horizontal guide rail to bore through holes in non-through tunnel to realize supply of wind, water and electricity on the opposite side, step d, arranging a protective wall on the opposite through tunnel in the previous step; step e, after arranging the protective wall, withdrawing cables, wind ducts and water pipes, blasting the non-through tunnel; and step f, after blasting, using excavation equipment for excavating. The construction method is safe and convenient, and improves the working efficiency, and avoids re-access of wind, water and electricity works for construction from the opposite side of through tunnel. Manpower, physical and time investment is reduced, and sustainable and stable development of mine construction and production can be maintained.

Description

technical field [0001] The invention belongs to the field of roadway construction for mines, and in particular relates to a construction method for a convenient roadway structure. Background technique [0002] In the construction of mine underground roadway, it is often encountered that the roadway and the well are connected, and the roadway is connected with the roadway. There are many unsafe factors such as the blasting warning is not in place, or the facilities on the opposite side are not in place, which brings great harm to the mine production. It is a very large potential safety hazard and has a great impact on the overall benefit of the mine. [0003] In addition, at present, all kinds of tunnel penetration protection work in mine shaft construction is time-consuming and labor-intensive, with greatly reduced safety, low labor efficiency, slow construction progress, and the workload of providing wind and water power is heavy and the cost is high. [0004] Therefore, i...
