Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel construction support reinforcement frame. Background Art

[0002] Highway tunnels and railway tunnels are often built in mountainous areas. The rock conditions of tunnels passing through mountainous areas are difficult to determine. When encountering weak surrounding rock, the mechanical excavation or blasting during tunnel construction may cause the risk of landslides if the rock is slightly disturbed. Therefore, it is necessary to support and reinforce the interior of the tunnel to avoid collapse.

[0003] During the disassembly and assembly process after use, due to the large size of the device and the limited space for placing the components, it is not convenient to disassemble and store the components. In addition, the tunnel usually experiences settlement and pressure during construction, which will cause pulling between the curved steel and the steel structure of the base. Over time, it may even be prone to breakage, which is not conducive to the disassembly, assembly and replacement of the installation base, supporting cross bars and supporting keels as a whole. Utility Model Content

[0004] The purpose of the utility model is to provide a tunnel construction support reinforcement frame, which is used to overcome the above-mentioned defects in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] According to the utility model, a tunnel construction support reinforcement frame comprises two front-to-back symmetrical mounting frames, the mounting frames are provided with left-right distributed plug-in slots, the plug-in slots are opened front and back, and the plug-in slots are opened upward at the same time, a plug-in rod is inserted between the two front and rear adjacent plug-in slots, the upper end of the mounting frame is connected with a support frame, two left-to-right symmetrical support frames are threadedly fixed on the mounting frame, the upper ends of the two support frames are hinged with reinforcement frames, the upper ends of the reinforcement frames are provided with support frames that abut against the inner circumference of the support frame, the two support frames are provided with card slots, and support plates extending front and back are provided in the card slots, and the front and rear ends of the support plates are provided with trapezoidal card blocks, which are inserted into the slots on the support frame by extending front and back. The block at the support plate is made of the same material as the support frame, and the curvature of the support plate is consistent with the curvature of the support frame. The lower end of the support frame is fixedly connected with an insertion block by a bolt, and the lower end of the insertion block is separately provided with a slot, and a second insertion rod is fixed on the insertion slot of the insertion block, and a positioning block is provided at the middle end of the insertion slot, and a mounting hole is provided on the insertion block, and the insertion block can be plugged and matched with the positioning block, and the bolt extends downward through the mounting hole and is threadedly connected to the middle end of the positioning block, and the left and right ends of the mounting frame are rotatably connected with threaded rods, and a threaded plate is threadedly connected to the threaded rod, and the threaded plate is fixed with two first insertion rods distributed front and back near the end of the mounting frame, and the insertion rod is provided with a mounting hole, and the first insertion rod can be inserted into the mounting hole.

[0007] The beneficial effects of the utility model are:

[0008] During use, it is easy to assemble and disassemble the mounting frame, the plug-in rod and the supporting frame. When a part is damaged or needs maintenance, only the corresponding part needs to be disassembled, which helps to reduce the difficulty of maintenance and overhaul, and reduces the time and labor costs required for maintenance.

[0009] When disassembling, the threaded rod can be rotated to disengage the first plug rod from the clamping connection with the plug rod, so that the plug rod can be removed from the mounting frame, thereby quickly separating the mounting frame and the plug rod part. When storing, the bolts on the supporting frame and the mounting frame can be rotated to disengage the bolts from the positioning block part, and the supporting frame can be removed from the upper end of the mounting frame for easy storage.

[0010] By supporting the upper end of the support frame with the reinforcement frame and the support frame, and installing a support plate on the upper end of the support frame, the user can lay a protective net on the upper end of the support frame and the support plate, thereby facilitating the support of soft rock in the tunnel.
