Description

Technical Field

[0001] The utility model relates to the technical field of tunnel support, in particular to a corrugated steel plate tunnel support structure. Background Technique

[0002] The function of tunnel support is to form a tunnel structure system with sufficient safety with the surrounding rock, which can withstand various possible loads, maintain the use clearance of the tunnel section, prevent the further collapse and deterioration of the surrounding rock, and provide a smooth surface for air circulation. Therefore, it is necessary to support in time after each section of the tunnel is excavated, and only when the support technology is adapted to the specific geological conditions of the rock formation at that place can good anti-deformation and anti-collapse effects be achieved.

[0003] When most of the existing corrugated steel plate support structures are in use, they are mostly spliced and fixed only by bolts. Although it is relatively convenient, when the entire support structure is under pressure, the bolts will be subjected to large extrusion and shear forces, resulting in the bolts being prone to breakage, and the butt joint support force is poor, affecting the stability of the structure.

[0004] At the same time, when the existing support structures are spliced and used, most of them are connected by welding after positioning, and then concrete is poured. Although this method is relatively stable, the welding efficiency is poor, affecting the installation efficiency of the support structure, and welding will generate a lot of waste gas, affecting the surrounding environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to further elaborate the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following is a detailed description of the specific implementation manner, structure, features and effects of the present utility model in combination with the accompanying drawings and preferred embodiments.

[0022] Please refer to Figures 1-4 As shown in the figure, a corrugated steel plate tunnel support structure includes a mounting plate 1. On both sides of the mounting plate 1, there are support plates 2. At two places on one side of the mounting plate 1, there are clamping grooves 3. At the top of the support plate 2, there is a clamping block 4. The surface of the clamping block 4 is movably connected to the inner wall of the clamping groove 3. The clamping block 4 and the clamping groove 3 are used in cooperation. In this way, it is convenient to connect the mounting plate 1 and the support plate 2, so that the connection between the mounting plate 1 and the support plate 2 is more stable. On one side of the clamping block 4, there is a bolt 5. The other side of the bolt 5 is used in cooperation with the mounting plate 1. In this way, the clamping block 4 and the mounting plate 1 can be connected by the bolt 5, thus facilitating the use of the support structure. On both sides of the surface of the mounting plate 1, there are fixed positioning rods 6. On the surface of the mounting plate 1, there is a fixed positioning sleeve 7. The surface of the positioning rod 6 is slidably connected to the inner wall of the positioning sleeve 7. In this way, by inserting the positioning rod 6 into the inside of the positioning sleeve 7, the connection between the mounting plate 1 and the support plate 2 can be connected. It can not only improve the connection effect between the mounting plate 1 and the support plate 2, but also improve the stress effect, avoiding the situation that all the forces are on the bolt 5 after the mounting plate 1 and the support plate 2 are connected, which affects the connection stability, and effectively improves the stability of the structure. The positioning rod 6 and the bolt 5 are designed with an interlaced structure. The bolt 5 and the positioning rod 6 are used in cooperation. In this way, after the bolt 5 is used, it will not block the positioning rod 6, avoiding the positioning rod 6 being blocked by the bolt 5 and affecting the connection with the positioning sleeve 7. On one side of the mounting plate 1 and the support plate 2, there is a fixed connecting plate 8. On the surface of the connecting plate 8, there is a mounting groove 10. Inside the mounting groove 10, there is a connecting mechanism 9. On the other side of the mounting plate 1 and the support plate 2, there is a fixed connecting plate 11. On the surface of the connecting plate 11, there is a positioning groove 12. The positioning groove 12 and the connecting mechanism 9 are used in cooperation. In this way, when multiple support structures are spliced and used, the two support structures can be connected through the cooperation of the connecting mechanism 9 and the positioning groove 12. It is not only more convenient, but also improves the connection efficiency, effectively improving the applicability of the support structure.

[0023] The connecting mechanism 9 includes a connecting block 91, which is rotatably connected to the inner wall of the mounting groove 10. The surface of the connecting block 91 is fixedly connected to a threaded rod 92, and the surface of the threaded rod 92 is threadedly connected to a positioning block 93. Under this action, the threaded rod 92 can be rotated to the inside of the positioning groove 12 by rotating the connecting block 91, and with the cooperation of the threaded rod 92 and the positioning block 93, the fixing plate 8 and the connecting plate 11 can be connected, so that the two supporting structures can be spliced together, which is not only more convenient but also improves the efficiency of splicing. One end of the threaded rod 92 is fixedly connected to the blocking plate 1 3. The diameter of the blocking plate 13 is larger than the diameter of the threaded rod 92, and the diameter of the blocking plate 13 is smaller than the width of the positioning block 93. Under this action, the blocking plate 13 can block the positioning block 93, so that it will not easily detach from the surface of the threaded rod 92 when it moves on the surface of the threaded rod 92, thereby avoiding the detachment of the positioning block 93 and affecting the connection of the supporting structure. The position of the connecting block 91 corresponds to the position of the positioning groove 12. The positioning block 93 is used in conjunction with the connecting plate 11. Under this action, the connecting mechanism 9 can be stuck in the inside of the positioning groove 12, thereby avoiding position deviation and affecting the connection of the two supporting structures.

[0024] It is worth noting that the technical features such as the mounting plate 1 and the support plate 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial arrangement method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: First, when the structure needs to be spliced, the staff inserts the positioning rod 6 into the positioning sleeve 7, and then pushes the mounting plate 1 to drive the clamping block 4 to embed into the clamping groove 3, and then uses the bolt 5 to connect the clamping block 4 and the mounting plate 1, thereby connecting the mounting plate 1 and the support plate 2, effectively improving the stability after connection. When the support structure needs to be spliced and used, the staff rotates the connecting block 91 to drive the threaded rod 92 to move to the positioning groove 12 of another support structure, and then rotates the positioning block 93 to squeeze and fix the fixing plate 8 and the connecting plate 11, so that they are connected together, and then they can be connected in sequence.
