Problems solved by technology

[0004] Manual construction is inefficient and labor-intensive, and the penetration depth is shallow, making it difficult to meet the construction requirements; and when the construction geology is sandy pebbles and other strata, it is easy to encounter large pebbles, resulting in the failure of the advanced conduit to continue to drive in or even to the ground. The leading catheter is bent, so another position needs to be re-inserted into the leading catheter

Abstract

The invention discloses an advance guide pipe driving device for an underground excavation trolley. The device comprises a beam body, a rock drill, a drilling oil cylinder, a movable pulley block, a clamping device, an advance guide pipe, a base and a propelling oil cylinder, and the rock drill is arranged on the beam body in a sitting manner and is connected with the beam body in a sliding manner. The advance guide pipe is fixedly connected with the rock drill and driven by the rock drill to rotate; the rock drill advances and retreats under the driving of the movable pulley block through thedrilling oil cylinder arranged in the beam body; and the propelling oil cylinder is matched with the base and is suitable for driving a longer advanced guide pipe. By means of the structure, advanceguide pipe driving is more convenient, and construction quality and construction efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of an undercut trolley used for tunnel construction, in particular to a leading duct device on an undercut trolley. Background technique [0002] In the construction of underground tunnels, grouting advanced conduit support construction technology is required. Advance conduit support requires the advance conduit to be driven into the soil layer at a certain angle and depth. However, in the process of primary support, the requirements for driving the grouting advance conduit are more stringent. The penetration depth of the advance conduit, its distribution on the section, and the angle between the advance conduit and the section directly affect the quality of the large-section primary support. The poor quality of the lead-in conduit directly leads to poor support effect, and it is easy to collapse in the subsequent construction process, which is easy to cause casualties and equipment damage, which directly a...
