Safety maintenance damping protection system for tunnel

Abstract

The invention discloses a safety maintenance damping protection system for a tunnel. A damping protection assembly is arranged on the outer side of a bearing frame, a buffer pipe is slidably mounted in a sliding hole, a positioning nail is slidably mounted in the middle of a guide opening, a fixed limiting piece and a movable limiting ring are in spot welding connection through a guide spring, the two ends of a spring plate are movably sleeved with connecting sleeves, the two ends of the bottom face of a pressure sensor are connected with the ends of the two induction plates through screws correspondingly, two adjacent guide pipes are slidably connected to the two ends of an induction connecting rod in a sleeving mode correspondingly, a connecting damping assembly is installed at the bottom end of a bearing frame, and protective lubricating assemblies are installed on the two sides of the bearing frame. A top plate of the system contacts with the inner wall of a tunnel and moves along with the vibration, a longitudinal damping spring and a spring plate are used for buffering in sequence, a rigid bearing frame is matched, multiple structures are used for damping under the condition that the supporting strength is guaranteed, the damping effect is improved, the influence of vibration on the bearing frame is relieved, the strength of the connecting position is higher, and looseness is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of tunnel safety maintenance, in particular to a safety maintenance shock absorption protection system for tunnels. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. In order to prevent collapse and mention the overall strength of the tunnel, supporting and strengthening structures are often installed in the tunnel to improve the safety of the tunnel. [0003] However, the tunnel support structures currently on the market are rigid supports. When encountering vibrations, the joints are easy to loosen, and the strength will decrease after long-term use, causing safety problems. Frequent inspections and maintenance are required, which brings a lot of inconvenience to use. Contents of the invention [0...
