Description

Technical Field

[0001] The utility model relates to the technical field of tunnel pipe shed construction, and specifically relates to a pipe shed guiding and directional drilling device. Background Technique

[0002] During the tunnel construction process, large pipe sheds are generally used for advanced support. The pipe shed is mainly composed of steel pipes and steel arch frames. The steel pipes are processed and drilled according to the design requirements, and cement slurry or cement mortar is poured into the pipes to improve the stiffness and strength of the steel pipes. This structure forms a support system with relatively high overall stiffness through the combination of steel pipes and steel arch frames, which can effectively prevent and limit the deformation of the surrounding rock, bear the early surrounding rock pressure in advance, and thus ensure the safety and smooth progress of the construction.

[0003] With the development of tunnel engineering, due to the influence of geological types, tunnel forms, and excavation methods, advanced pipe sheds are often installed during tunnel construction. Before the installation of the advanced pipe shed, it is necessary to position and drill the holes for the advanced pipe shed, and then further accurately position the pipe shed for construction. Usually, when positioning the holes for the pipe shed, a drill bit is used to drill according to the measured position. However, during the drilling process, the rod body will shake in space due to mechanical movement, so there is a risk of deviation in the drilling angle. In addition, during the drilling process, it is necessary to timely master the drilling angle and make targeted corrections to ensure the accurate guiding and positioning of the advanced pipe shed. For this reason, we propose a pipe shed guiding and directional drilling device. Content of the Utility Model
