Tunnel arch support device for tunnel construction

Abstract

The invention discloses a tunnel arch supporting device for tunnel construction. The tunnel arch supporting device comprises a supporting frame, wherein one side of the bottom of the supporting frameis provided with a transverse plate, and the top end of the transverse plate is provided with a transmission assembly. The tunnel arch supporting device for the tunnel construction has the advantagesthat the structure is scientific and reasonable, the use is safe and convenient, the transmission assembly is arranged, and the action of a first manual hydraulic cylinder, a sliding block and supporting rods provides convenience for pushing a connecting column to move upward, thereby driving the supporting rods to move to the two sides simultaneously; the operation is simple, and the time is saved; the action of a guide rod provides convenience for guiding the sliding block to move longitudinally, thereby avoiding the situation that the sliding block shakes to affect the supporting effect; support rods are arranged, and the action of the support rods, movable shafts, a sliding groove and fixing plates provides convenience for sliding the support rods; the action of a fixed threaded rod provides convenience for fixing the fixing plates and the support rods, thereby adjusting the angles of the support rods, so that the support rods support the supporting rods and form a triangle with the supporting rods and the transverse plate, thereby improving the overall stability of the device.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to a tunnel arch support device for tunnel construction. Background technique [0002] 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, and mine tunnels. During tunnel construction, it is often encountered due to There is no solid foundation support, so in the process of new stress formation, the foundation bearing capacity is insufficient and correspondingly leads to practical problems such as tunnel instability and collapse, which seriously affects the safety of people and equipment, and hinders the progress of construction. In the actual construction process, In order to solve the above-mentioned practical problems such as tunnel instability and landslides, it is necessary to quickly and effectively support the excavation section in time du...
