Description

Technical Field

[0001] The utility model relates to the technical field of tunnel reinforcement, in particular to a tunnel reinforcement supporting device. Background Art

[0002] Reference Figure 1 A belt conveyor 6 and a large number of pipelines and cables are arranged in the coal mining face tunnel 1 of the coal mine. They are generally installed on the side and shoulder of the tunnel by hanging or brackets. For example, the side of the tunnel is equipped with an emulsion supply pipe 2, an emulsion return pipe 3, a spray pipe 4 and other pipelines, and the shoulder is equipped with a power cable hook 5, etc., to ensure the smooth mining operation of the mine.

[0003] In coal mine tunnel engineering, the support system is a key structure to ensure the safety of the working face and prevent surrounding rock deformation and collapse. At present, anchor nets or anchor nets superimposed on anchor cables are widely used in coal mine tunnel engineering. However, under certain geological conditions, such as aquifers in three soft strata, these support methods may fail due to cementation of the rock strata, which in turn causes the tunnel roof to sink or even collapse. To address this problem, it is usually necessary to reinforce and protect the failed tunnel roof. Figure 2 Generally, coal mines will use trapezoidal I-beam sheds or single pillars superimposed on π-shaped steel beam sheds to reinforce and support the roof, but the I-beam beam 8 or the single shed will occupy the width of the tunnel, and the I-beam shed legs 7 will interfere with the pipes and cables suspended from the tunnel wall. The original layout of the pipes and cables on the tunnel wall in the tunnel 1 needs to be arranged, resulting in insufficient driving width and vehicles being unable to pass. After adding the I-beam shed or the single shed, the maintenance width on the belt side will be insufficient (Article 90 of the "Coal Mine Safety Regulations" stipulates that it should not be less than 0.5m). After adjusting the belt outward, it will cause the belt to deviate.

[0004] In view of this, how to achieve reinforcement and protection of the tunnel roof without adjusting the original design of the existing tunnel has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a tunnel reinforcement and support device, which can reinforce and protect the tunnel roof without adjusting the original design of the existing tunnel.

[0010] Support rods are respectively mounted on the two brackets at both ends, and the support rods are used to support the top plate of the tunnel.

[0011] Further, the bracket comprises:

[0012] a support plate abutting against the side of the laneway and connected to the other end of the connecting rod; and

[0013] A top plate is vertically fixedly connected to the top end of the support plate, and the support rod is mounted on the top plate.

[0014] Furthermore, the bracket also includes a rib plate fixedly connected between the support plate and the top plate.

[0015] Furthermore, the support plate is provided with two connection holes, the two connection holes are respectively located on both sides of the rib plate, and the connection rod is fixedly connected to the support plate through the connection holes.
