Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated non-disassembly formwork systems, and in particular relates to a multi-scenario adaptable prefabricated non-disassembly formwork system. Background Art

[0002] In the field of tunnel engineering, tunnel reinforcement and maintenance operations have always been a key link in ensuring the safety of tunnel structures and extending their service life. However, traditional tunnel reinforcement and maintenance methods are highly dependent on manual operations, especially the installation of formwork, which is not only inefficient but also has significant safety hazards. Currently, tunnel reinforcement and maintenance is carried out by building scaffolding inside the tunnel, and then workers lift the heavy formwork to a height of several meters to carry out the work. This process not only tests the physical strength and endurance of the construction workers, but also poses a severe challenge to the safety of the operation.

[0003] Conventional prefabricated formwork, as an important component of tunnel reinforcement and maintenance, is often designed to be heavy based on structural strength and durability considerations. In a limited working space, construction workers need to work together to barely lift the prefabricated formwork and accurately install it in place. This high-intensity physical labor can easily lead to fatigue among construction workers, greatly increasing construction time, and in a high-altitude working environment, once an accident occurs, the consequences will be disastrous. In addition, tunnel reinforcement is generally carried out at night after the vehicle stops operating, and the reinforcement equipment needs to clear the site and complete the site cleanup before the vehicle operates the next day. Therefore, tunnel repair only takes 2 to 3 hours a day, and conventional tunnel reinforcement and repair technology is difficult to complete a large amount of tunnel reinforcement and repair work. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing tunnel reinforcement and maintenance requires manual construction of scaffolding and manual installation of prefabricated templates at a height, but the existing prefabricated templates are generally heavy, and it is very laborious to manually lift the entire template up several meters and install it, and there are safety hazards. Tunnel reinforcement is generally carried out after the vehicle stops at night, and the reinforcement equipment needs to clear the site and complete the on-site cleaning before the vehicle operates the next day. Therefore, the tunnel repair only takes 2 to 3 hours a day, and conventional tunnel reinforcement and repair technology is difficult to complete a large amount of tunnel reinforcement and repair work. Moreover, if a hole in the tunnel is damaged, it is necessary to repair the entire template, which wastes resources and labor costs. Therefore, a multi-scenario adaptive prefabricated non-disassembly template system is proposed.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a multi-scenario adaptive prefabricated non-disassembly formwork system, comprising a plurality of formwork units, wherein the plurality of formwork units are connected to form a reinforced formwork, wherein the shape of the reinforced formwork matches the shape of the inner wall of the tunnel component, adjacent formwork units are connected by a sealing structure, bolts pass through the formwork units and are connected to the tunnel component, and a reinforced filling layer is arranged between the reinforced formwork and the tunnel component.

[0006] As a further description of the above technical solution:

[0007] A mounting groove is provided on one side of the template unit, a sealing gasket is provided on the inner wall of the mounting groove, and a connecting piece is provided on the other side of the template unit. When adjacent template units are connected, the connecting piece is connected inside the sealing gasket.

[0008] As a further description of the above technical solution:

[0009] The connecting piece is in the shape of a cylinder with a large inner diameter and a small outer diameter, and the connecting piece passes through the sealing gasket and is connected to the adjacent template unit. As a further description of the above technical solution:

[0010] The reinforcement filling layer is a concrete layer, and carbon fibers are arranged in the concrete layer.

[0011] As a further description of the above technical solution:

[0012] The template unit is provided with a plurality of mounting holes, and the plurality of mounting holes are evenly arranged in the middle position of the template unit.

[0013] As a further description of the above technical solution:

[0014] Electrodes are arranged in the concrete layer.

[0015] As a further description of the above technical solution:

[0016] The electrodes are connected to a data acquisition unit of a monitoring system via a wire.

[0017] As a further description of the above technical solution:

[0018] The monitoring system is provided with an alarm device, and the alarm device is wirelessly connected to the mobile phone terminal.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In the present invention, the prefabricated template is designed into a plurality of template units, and is designed according to the shape of the tunnel component. When the tunnel needs to be reinforced and repaired, the template units are installed on the inner wall of the tunnel one by one by bolts. After the installation is completed, the gap between the tunnel and the template unit is filled. This structure designs the template structure into a plurality of units, which is not only convenient for workers to carry out individual installation and reduce the stress degree of workers during construction, but also if the installation is not completed on the same day, the construction can be continued the next day without starting from the beginning, which greatly increases the construction efficiency and reduces the construction difficulty.

[0021] 2. In the present invention, by pre-embedding connectors and sealing pads in the template units, the template units are connected through connectors passing through the sealing pads, and adjacent template units are squeezed against each other to achieve sealing, thereby avoiding water leakage during the pouring of concrete. This structure is not only easy to install, but also can improve the carbon fiber in the reinforced filling layer to more accurately monitor the entire repair structure. Once an abnormality occurs, the abnormal information will be sent to the construction worker's mobile phone terminal to remind him. At the same time, after it is designed into several units, there is no need to install the entire module for small damage, and specific template units can be installed according to the location of the damage, which not only saves resources but also saves labor costs.

[0022] 3. In the present invention, by setting electrodes in concrete, these electrodes can form a conductive connection with carbon fiber, so as to monitor the resistance change inside the concrete. The electrodes are connected to the data acquisition part of the monitoring system through wires to realize signal transmission and communication. When the carbon fiber concrete is subjected to external force, its internal resistance value will change. This change can be transmitted as an electrical signal through electrodes and wires. The monitoring system receives these electrical signals and converts them into corresponding stress values ​​or strain values ​​for real-time monitoring and analysis. When the monitored physical quantity exceeds the preset threshold, the monitoring system will trigger the early warning or alarm device and send information to the mobile phone of the relevant personnel to remind the relevant personnel to take necessary measures. This structure not only improves construction efficiency, saves labor costs and resources, but also monitors the state of reinforcement and repair. Once an abnormality occurs, it can be rescued in time to avoid causing unnecessary dangers in the tunnel. BRIEF DESCRIPTION OF THE DRAWINGS
