Problems solved by technology
[0004] In view of the related technologies mentioned above, the inventor believes that when the tunnel is supported by the initial support during the excavation process, as the tunnel excavation proceeds, it is necessary to continuously lay the initial support near the excavation point, and the later It is necessary to disassemble the initial support, which requires a lot of manpower and material resources

Embodiment
[0038] refer to figure 1 , a tunnel support structure, comprising a fixed platform 1, a positioning plate 2 is installed above the fixed platform 1, four rollers 3 are installed on the fixed platform 1, and two parallel columns 4 are connected to the fixed platform 1. The upper ends are fixedly connected with the positioning plate 2. When the tunnel support structure is in use, the operator moves the tunnel support structure to the excavation point of the tunnel by moving the rollers 3.
[0039] refer to figure 1A guide rail 37 matching the roller 3 is installed under the roller 3. When the operator moves the positioning platform through the roller 3, the roller 3 moves along the guide rail 37, reducing the friction between the roller 3 and the bottom surface, and the operation is more labor-saving and convenient; The guide rail 37 includes a plurality of guide rods 38, and the adjacent guide rods 38 are clamped. When the roller 3 moves forward, the operator removes the guide...

The invention discloses a tunnel supporting structure and a using method thereof. The tunnel supporting structure comprises a fixed table, a positioning plate is arranged above the fixed table, the fixed table is provided with a plurality of rolling wheels and connected with two stand columns, the two stand columns are fixedly connected with the positioning plate, the fixed table is provided with an adjusting assembly for driving the two stand columns to move up and down, the positioning plate is provided with a plurality of supporting assemblies, the supporting assembly comprises a first supporting plate, a second supporting plate and a transverse plate, and the transverse plate is fixedly connected with a first elastic layer. The fixed table is moved to a tunnel excavation point, the positioning plate is adjusted to the position close to the top of the tunnel through the adjusting assembly, all first elastic layers are tightly attached to the inner wall of the top of the tunnel, and the tunnel is supported; and along with advancing of tunnel excavation, the first elastic layers are separated from the inner wall of the top of the tunnel through the adjusting assembly, then the fixed table moves along with the adjusting assembly through the rolling wheels, then a new excavation point is supported, operation is easy and convenient, and manpower and material resources can be saved.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a tunnel support structure and a method for using the same. Background technique [0002] Tunnels are a relatively common transportation facility that allows pedestrians and vehicles to pass through, and some tunnels are also dedicated to the passage of vehicles such as trains and subways. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, etc. During the construction and excavation of the tunnel, a supporting structure is generally provided to prevent deformation or collapse of the surrounding rock. [0003] In the related art, during the construction of the tunnel, landslides, loosening of soil and rocks, etc. may occur. In order to control the stress release and deformation of the surrounding rock and increase the safety and strength of the structure for subsequent construction, the initial support is generally used in the excavated tun...
