Problems solved by technology

[0010] The purpose of the present invention is to propose a kind of underground tunnel construction equipment, which can not only solve the problem that the rod storage device for horizontal directional drilling in the prior art is difficult to continue or change rods due to the inconvenient return of the propeller to a certain position of the main engine, but also It can solve the problem that the volume and load of the disc-type rod storage device increase due to the installation of the rod storage device on the push beam

Abstract

The invention relates to underground tunnel construction equipment which comprises a first operation arm (1) and a second operation arm (2), wherein an anchor rod pushing device (3) which is used for pushing an anchor rod (5) to move is arranged on the first operation arm (1), an anchor rod storage device (4) which is used for storing the anchor rod (5) is arranged on the second operation arm (2), the first operation arm (1) and/or the second operation arm (2) are/is of extension type, and the anchor rod pushing device and the anchor rod in the anchor rod storage device are mutually close by the extension of the first operation arm and/or the second operation arm after the anchor rod pushing device (3) completes anchor rod pushing. The anchor rod pushing device and the anchor rod storage device are mounted in different positions respectively, the problem that the size and the bearing load of the disc type anchor rod storage device are increased due to that fact that the anchor rod is attached to a pushing beam can be solved, the operation arms are of extension type, and the problem that the anchor rod is difficult to continue due to the fact that a horizontal directional drill is inconvenient to return to a main machine can also be solved.

Description

technical field [0001] The invention relates to the technical field of underground tunnel construction, in particular to underground tunnel construction equipment. Background technique [0002] When supporting tunnels in weak strata, relatively large-diameter advanced small conduits or pipe sheds are often used for advanced support to strengthen the stratum, that is, pipe walls are arranged at a certain angle along the excavation outer contour. Conduits with small holes, inject cementing grout into the conduit, fill and consolidate the broken surrounding rock or clay layer with grout, so as to achieve the effect of reinforcement and water blocking, so that in tunnel construction with poor geological conditions, it can be used for safety Hole entry and collapse treatment create good construction conditions. [0003] At present, there are mainly two methods for the construction of conduits, one is to use drilling equipment to directly advance the conduit to a set depth; the o...
