Description

Technical Field

[0001] This utility model relates to the field of tunnel construction auxiliary equipment, specifically a tunnel secondary lining shaping tool. Background Technology

[0002] Tunnels are specially designed underground or enclosed passages. During the construction of tunnels, the tunnel walls need to be protected. The primary lining provides basic support, and the secondary lining further enhances the overall structural strength of the tunnel, ensuring that the tunnel can resist geological pressure and external loads for a long time. In the protection process, prefabricated plywood is used and installed near the wall. Then, concrete is poured to form a detached secondary lining.

[0003] Traditional wooden formwork involves assembling or transporting each piece individually, which is inefficient. The piece-by-piece installation and disassembly can easily cause deformation or damage to the formwork, resulting in fewer reuses and a large consumption of formwork. Furthermore, after replacing the formwork, additional bolt holes need to be drilled, affecting construction efficiency and increasing construction costs such as materials and labor. At the same time, the piece-by-piece assembly method is prone to cutting deviations when replacing parts of the formwork and re-fitting the formwork, resulting in poor joints between the new and old formwork and inconsistent rigidity. This can easily lead to surface quality problems such as grout leakage and vertical "wavy" deformation, increasing the cost of secondary treatment. Utility Model Content

[0004] The purpose of this utility model is to provide a tunnel secondary lining shaping tooling to solve the following technical problems: the assembly and transportation efficiency of the template in a limited space is low, the installation and disassembly of the template is prone to deformation and damage, resulting in high construction costs, and the overall integrity of the assembled template is poor.

[0007] The fixing assembly also includes two dampers. One end of the damper is fixedly connected to the inside of the wooden template, and the other end is fixedly connected to the second limiting block. The bottom of the second limiting block abuts against the top of the first limiting block. A push rod is slidably connected to the outer wall of the fixing rod. The outer wall of the push rod is slidably connected to the inside of the wooden template, and the bottom end of the push rod abuts against one side of the second limiting block and the top of the first limiting block.

[0008] The transport component includes a transport vehicle, the interior of which is equipped with a lifting component.

[0009] As a preferred embodiment of this utility model: the lifting assembly includes a hinge, the hinge is disposed inside the transport vehicle, a base plate is fixedly connected to the bottom side of the interior of the transport vehicle, a lifting plate is slidably connected to the interior of the transport vehicle, and the bottom of the vertical square timber is installed on the top of the lifting plate;

[0013] As a preferred embodiment of this utility model: a limiting plate is fixedly connected to the outer wall of the fixing rod, the outer wall of the limiting plate is slidably connected to the inside of the push rod, a spring is fixedly connected to the top of the limiting plate, the top end of the spring is fixedly connected to the inside of the push rod, and the spring is sleeved on the outer wall of the fixing rod.

[0014] As a preferred embodiment of this utility model: sealing plates are fixedly connected to the bottom front and rear sides of the two wooden templates, and the outer wall of the sealing plate is slidably connected to the top of the adjacent wooden templates.

[0015] As a preferred embodiment of this utility model: the interior of the wooden template has a plurality of evenly distributed bolt holes, and the interior of the bolt holes is threaded with tie bolts, one side of which abuts against the front side of the transverse square timber.

The vertical square timber can be installed on the top of the template by the lifting plate, and then the vertical square timber can be transported by the transport component. This solves the problem of large volume and weight of the template and greatly improves the template transfer efficiency.

[0021] (4) This utility model can drive the threaded rod to rotate by starting the motor, which in turn drives the moving block to move. The moving block can drive the lifting plate to rise and fall through the cooperation of the hinge. During transportation, the lifting plate can be lowered into the inside of the transport vehicle to improve the stability of transportation. After transportation is completed, it can be raised out to facilitate the removal of it from the inside of the lifting plate. Attached Figure Description

The movement of the moving block 46 drives one side of the hinge 41 to move, thereby driving the lifting plate 43 to rise and fall. Lowering the lifting plate 43 into the interior of the transport vehicle 31 can improve the stability of the vertical square timber 11. Raising the lifting plate 43 to the top of the transport vehicle 31 makes it easy to take it out.
