Abstract

The invention provides a device and a method for reinforcing a tunnel portal mountain landslide. The device for reinforcing the tunnel portal mountain landslide comprises a lattice beam, a plurality of anchor ropes, a slide resistant device and a plurality of first grouting pipes;the lattice beam is arranged on the surface of a mountain and located above rear edge cracks in a mountain landslide, a first end of each anchor rope is embedded in a rock mass, and a second end of each anchor rope is arranged on the lattice beam in a penetrating mode and connected with the lattice beam; the slide resistant device is arranged at the tunnel portal and embedded under the road surface of a tunnel; and a plurality of grouting holes are formed in the outer wall of each first grouting pipe, a plurality of holes are formed in the rock masses between the lattice beam and the slide resistant device, the first grouting pipes are arranged in the holes in a one-to-one mode, and the first grouting pipes are used for grouting mud into the corresponding holes. According to the device for reinforcing the tunnel portal mountain landslide provided, the overall self-stability of the mountain is improved, the occurrence of a secondary disaster during tunnel construction is effectively prevented, and the security risk is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a device and method for reinforcing landslides at tunnel entrances. Background technique [0002] Since the 20th century, with the development of my country's transportation and the advancement of technology, highways and railways have developed rapidly, domestic transportation is extending in all directions, and roads and railway tunnels have gradually increased. [0003] my country is a mountainous country. The construction of highways and railways will inevitably pass through mountainous areas. Due to the different geological conditions in different parts of the country, in some mountainous areas, the ground undulations are large at the entrance and exit areas of the tunnel, the surface water is developed, and the surface soil is in an unstable state. During the construction of the open tunnel, the soil above and around the open tunnel is prone to landslides, formin...
