Abstract

The invention belongs to the technical field of tunnel construction, and particularly relates to safety protection intelligent equipment for well and tunnel operation. The safety protection intelligent equipment comprises a pressure sensing mechanism and a protection mechanism, the bottom of the pressure sensing mechanism is connected with the top of the protection mechanism through a bolt, and the pressure sensing mechanism comprises a pressure lever, a pressure piston and a pressure bearing frame, the pressure lever is installed above the pressure piston, and the right end of the pressure lever is hinged with the right end of the pressure bearing frame. The safety protection intelligent equipment and a safety protection method for well and tunnel operation has the advantages that a second clamping block enables a limiting shaft to move outwards, a limiting block is promoted to slide to the position above a limiting groove, a first clamping part clamps again, the limiting block falls and is embedded into a limiting fixing groove, and limiting and fixing are completed; the clamping of the first clamping part and the clamping of a second clamping part cannot be loosened due to release of a clamping connecting rod, the stability of the connecting position of a supporting pipeline is greatly enhanced, the invention further provides a safety protection method adopting the safety protection intelligent equipment for well and tunnel operation, and the safety protection method comprises the steps of equipment installation, pressure bearing and reducing, repairing and limiting and the like.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to an intelligent device and a safety protection method for pit tunnel operation safety protection. Background technique [0002] When working in the tunnel, a large number of pipe supports will be installed in advance to support the tunnel. When construction is carried out on soft ground, due to the soft ground and the flow of groundwater, it is very easy to cause deformation of the inner wall of the tunnel, which often leads to loose connections at the joints of the supporting pipes. The opening caused the support to collapse, and the connection structure at the existing pipe connection was extremely unstable and unable to adjust itself. [0003] The Chinese patent with the publication number CN110295944B discloses a tunnel protection unit, which includes more than one set of protection devices equidistantly arranged on both sides of the tunnel. The device...
