Description

Technical Field

[0001] This utility model relates to the field of highway tunnel construction technology, specifically a highway tunnel construction support frame. Background Technology

[0002] A tunnel is a passage dug out of an existing building or earth-rock structure. It is an engineering structure buried in the strata and is a form of human utilization of underground space. A tunnel construction support frame is a construction device that supports and stabilizes the interior of a tunnel. Its main function is to provide support to the inner wall of the tunnel to prevent tunnel collapse.

[0003] For example, announcement number CN219974520U, named "Tunnel Construction Support Frame," includes multiple support steel frame units and at least one protective steel plate. The support steel frame units are spaced apart along the tunnel's extension direction. Each support steel frame unit includes an outer support steel frame and an inner support steel frame. The outer wall of the outer support steel frame contacts and supports the inner wall of the tunnel. The inner support steel frame is located inside the outer support steel frame and is fixedly connected to it. A gap is provided between the outer support steel frames. The protective steel plate is fixedly connected to the inner support steel frames of two adjacent support steel frame units on both sides. The protective steel plate and the two adjacent support steel frame units form a spatial groove. This spatial groove allows falling rocks from the tunnel's inner wall to fall into it, providing support to the tunnel's inner wall, shielding it from falling rocks, preventing injuries, and ensuring the safety of tunnel construction personnel.

[0004] The existing tunnel support frame can only support the location of the steel frame when in use, and there is no support structure in the space between the two, which leads to a decrease in the overall support effect and affects safety. Therefore, it does not meet the current needs, so a new support frame for highway tunnel construction is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a support frame for highway tunnel construction, in order to solve the problem mentioned in the background art that the existing tunnel support frame can only support the location of the steel frame when in use, and there is no support structure in the space between the two, which leads to a decrease in the overall support effect and affects safety.

[0013] Preferably, a base is installed on the inner side wall of the bottom of the support frame, and the base is fixed to the ground by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In this utility model, two sets of support frames are located at the front and rear ends respectively, which are used to support and reinforce. On this basis, a support plate is installed between the two support frames. The support plate can support and reinforce the space between the two support frames.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of a highway tunnel construction support frame, comprising: a first support unit 1, which consists of two sets of support frames 101, with a base 102 installed on the inner side wall of the bottom of the support frame 101. The base 102 is fixed to the ground by bolts, and the support frame 101 is fixed to the ground by the base 102 to improve the support strength of the support frame 101. A second support unit 2 is installed between the support frames 101, and the second support unit 2 includes a support plate 201. A plurality of docking holes 202 and through holes 103 are respectively opened on the outer wall of the support plate 201 and the support frame 101. The docking holes 202 and through holes 103 are arranged at equal intervals. A reinforcing connecting frame 3 is installed between the second support unit 2 and the support frame 101. 3 is composed of multiple reinforcing rods 301, with each reinforcing rod 301 having its two ends passing through the corresponding docking holes 202 and through holes 103. Two sets of support frames 101 are located at the front and rear ends respectively, serving as support and reinforcement. On this basis, a support plate 201 is installed between the two support frames 101. The support plate 201 can support and reinforce the space between the two support frames 101. The support plate 201 and the support frame 101 are connected and combined together by a reinforcing connecting frame 3. The reinforcing connecting frame 3 is composed of multiple reinforcing rods 301, which pass through the docking holes 202 and through holes 103 at various positions. It can not only combine the support frames 101 at both ends with the support plate 201, but also strengthen the support strength of the support plate 201 and improve the protection effect.

[0026] In addition, both the support plate 201 and the support frame 101 are arched structures. The arched structure is more in line with the shape of the tunnel, so that after the support is reinforced, the top and sides of the arched structure can effectively support and bear the load, thus improving the support effect.

[0027] Based on the above method, according to the actual situation at the tunnel site, two sets of support frames 101 can be erected at both ends of the required support position, and support plates 201 of appropriate size can be installed between them. The docking holes 202 at the support plates 201 are aligned with the through holes 103 of the support frames 101. After alignment, multiple reinforcing rods 301 are inserted for reinforcement.

[0028] Furthermore, such as Figure 3As shown, multiple reinforcing plates 203 arranged equidistantly on the inner wall of the support plate 201 are installed. The reinforcing plates 203 have an arched structure, and multiple reinforcing ribs 204 are installed between the reinforcing plates 203 at equal intervals. The installation of multiple reinforcing plates 203 can improve the strength of the support plate 201 itself. The installation of multiple reinforcing ribs 204 further improves the support strength of the support plate 201. The reinforcing plates 203 are also arched, which fits the shape of the support plate 201. The reinforcing ribs 204 are installed at equal intervals at different positions of the arched structure to improve the support strength at different positions.

[0029] Please see Figure 4 The second support unit 2 has a support unit 4 installed at its bottom. The support unit 4 consists of two sets of support platforms 401. A support frame 402 is installed below the support platform 401. The support frame 402 is fixed to the support frame 101 by bolts. This detachable structure allows users to easily assemble it on site. Reinforcing ribs 403 are installed on the outer wall of the support frame 402. Multiple sets of extension brackets 404 are installed between the support platforms 401. The support unit 4 is used to connect the two support frames 101 and support the support plate 201. Specifically, the support platform 401 and the support frame 402 support the side bottom of the support plate 201. The extension brackets 404 connect the two support platforms 401 and also support the bottom of the support plate 201. The support frame 402 adopts a reinforcing rib 403 structure, which can improve the support and reinforcement effect.

[0030] Please see Figure 5 An assembly unit 5 is installed on the outer wall of the support frame 101. The assembly unit 5 includes an assembly table 501, an assembly frame 502 installed below the assembly table 501, a screw 503 installed in an opening in the outer wall of the assembly table 501, a shank 504 installed at the upper end of the screw 503, and a drill bit 505 installed at the lower end of the screw 503. The assembly unit 5 is used to further improve the support of the support frame 101 after it is fixed. Specifically, it is fixed by bolts through the assembly frame 502. The disassembly structure on the outer wall of the support frame 101 is simple and easy for users to assemble on site. The screw holes of the assembly table 501 are equipped with corresponding screws 503. The screws 503 are rotated downward by the handle 504 to insert the drill bit 505 into the ground for support and reinforcement, thereby improving the support and fixation strength of the support frame 101. When disassembling, the screws 503 are moved upward by rotating the handle 504 to remove the drill bit 505 from the ground, which is convenient for users.
