Problems solved by technology
However, this invention still has the following disadvantages or deficiencies: (1), the opening sequence of the pipe shed holes and the construction sequence of the pipe shed pipes are not disclosed; (3) The rotational freedom of the pipe rammer is low. During the construction process, the air compressor and the pipe rammer need to be replaced and installed on different work platforms, which increases the difficulty of construction and prolongs the construction period.

Embodiment Construction
[0024] Next, the tunnel pipe shed construction method and device of the present invention will be described in detail with reference to the accompanying drawings.
[0025] First of all, in order to speed up the construction progress, it is necessary to ascertain the geological conditions in advance, measure the buried depth and other issues, and then figure 1 As shown, in step S1, the pipe shed opening contour line is determined on the working face of the tunnel to be constructed, and 27 hole positions are marked on the pipe shed opening contour line, and the 27 hole positions are divided into nine A Hole position, nine B hole positions and nine C hole positions, the A hole position is distributed in the middle and upper part of the opening contour line of the pipe shed and forms the A hole position area, and the B hole position is distributed in the lower left part of the pipe shed opening contour line And form the hole position area B, the hole position C is distributed in t...

The invention discloses a tunnel pipe roof construction method and device. The device comprises a material bearing mechanism, a clamping moving mechanism and a pipe roof pushing mechanism, wherein thematerial bearing mechanism is used for bearing a plurality of sections of steel pipe roofs, the clamping moving mechanism is located on the side, close to an entrance of a tunnel, of the material bearing mechanism and comprises a base, rolling wheels which are arranged below the base, a supporting seat which is fixed to the part above the base, a supporting arm which can be rotatably connected with the top of the supporting seat and a clamping unit which is arranged at the other end of the supporting arm through suspending, the clamping unit is used for clamping seamless steel pipes from thematerial bearing mechanism to pipe roof holes formed in the entrance of the tunnel, and the pipe roof pushing mechanism is located on the side, close to the entrance of the tunnel, of the clamping moving mechanism and used for pushing each section of the steel pipe into a corresponding hole.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a tunnel pipe shed construction method and device. Background technique [0002] In the construction of shallow buried underground excavation method, for the surrounding rock with poor self-stabilization ability, pre-support measures are often used to achieve the purpose of strengthening the surrounding rock and stabilizing the working face. Advance pipe shed pre-support is a commonly used pre-support measure. Pipe shed generally refers to a part or all of the section of the underground project, which is arranged circularly at a certain interval to form a shed protection structure. Its purpose is to provide a temporary support method to enhance the bearing capacity of the stratum in advance for safe excavation under special geological conditions. It is mainly used in weak and gravel formations and soft rocks, rock piles and broken zones. [0003] At present, during ...
