According to the method, the tunnel inner supports and the reinforcing are firstly carried out on the two ends of the landslide tunnel structure, further deformation of the tunnel is prevented, and then the reinforcing structures outside the tunnel inner hole are effectively combined by the anti-slide piles and the anchor cables, so that the integral stability of the tunnel in the horizontal and vertical directions is kept, the anti-slide capability of the tunnel structure is improved, and the effect of reinforcing the tunnel is achieved.
Description
Technical Field
The utility model relates to the technical field of tunnel construction, in particular to a temporary reinforcing structure suitable for a landslide tunnel.
Background
In order to meet the requirements of western economic development on transportation, highways and railways must be constructed in mountainous areas. However, the mountainous area is a frequently occurring area of landslide, and due to the topographic conditions and frequent earthquakes, road engineering for construction in the mountainous area can often encounter adverse geologic bodies such as landslide, and as such, when a tunnel needs to pass through a landslide body in a tunnel form, a reinforcing structure suitable for a landslide tunnel is needed to solve the problem because the tunnel structure does not have an anti-skidding function, and the reinforcing structure has the characteristics of economy, reasonability, simplicity in construction and the like and meets the requirement of environmental protection.
For the existing sliding tunnel, it needs to be reinforced and maintained, and for this reason, the common reinforcing method is to add support in the tunnel, set up the anti-slide piles of slope body, etc., but there is no reinforcing method that can effectively combine the reinforcing structure outside the tunnel in the tunnel by using the anti-slide piles.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a temporary reinforcing structure suitable for a landslide tunnel, which effectively combines reinforcing structures inside and outside a tunnel, improves the anti-skid capacity of the tunnel structure and achieves the effect of tunnel reinforcement.
The technical scheme of the utility model is as follows:
a temporary reinforcing structure suitable for a landslide tunnel comprises two in-tunnel support assemblies respectively arranged at two ends of the tunnel structure and a plurality of anti-slide piles arranged on one side of the tunnel structure; the support assembly in each hole comprises two inclined support rods, two horizontal support rods and an arched support plate, the top ends of the two inclined support rods are supported and connected to the arched support plate, the bottom ends of the two inclined support rods are fixed to the bottom of the tunnel structure, the bottom ends of the two inclined support rods are adjacent to the two bottom ends of the arch crown of the tunnel structure respectively, the outer ends of the two horizontal support rods are fixed to the arched support plate, the inner ends of the two horizontal support rods are fixed to the corresponding inclined support rods respectively, and therefore the arched support plate is supported and fixed to the arch crown of the tunnel structure through the two inclined support rods and the two horizontal support rods; the anti-slide piles are uniformly arranged along the walking direction of the tunnel structure, and each anti-slide pile is fixedly connected with the tunnel structure through a corresponding anchor cable.
The anti-slide piles are all located at the positions 1-2m on the left side of the tunnel structure.
And each anti-slide pile is provided with two anchor heads in advance, each anchor head is connected with a corresponding anchor cable, and each anti-slide pile is fixedly connected with the tunnel structure through the two anchor cables to realize obliquely upward and obliquely downward tensioning connection.
The anchor cable is formed by splicing four strands of high-strength low-relaxation steel wires.
The utility model has the advantages that:
the arched supporting plate is fixedly arranged at the arch crown of the tunnel structure through the two inclined supporting rods and the two horizontal supporting rods, and the anti-slide pile is connected to the left side of the tunnel structure through the anchor cable; the anti-slide pile has anti-slide and stretching effects, the thrust of landslide on the mountain side of the tunnel is transferred to the anchor cable, and the anti-slide pile is restrained in the horizontal direction, so that the deflection of the tunnel structure is greatly reduced, the internal force and the displacement of the tunnel structure are greatly improved, and the deformation of the tunnel is well controlled.
