The tunnel lining end formwork plays a crucial role in tunnel construction, and its technical condition directly impacts the quality of the tunnel lining and construction efficiency.

[0003] In existing technologies, the materials used for tunnel lining end formwork mainly include wood, steel, and plastic. Traditional tunnel lining end formwork has insufficient sealing performance, easily leading to grout leakage and affecting lining quality. Meanwhile, the fixing of the waterstop is a critical step in the construction of tunnel lining end formwork. Traditional methods, such as wire binding, are not only complex to construct but also have poor fixing effects, easily causing waterstop misalignment or damage. Furthermore, different geological conditions and construction environments place different requirements on tunnel lining end formwork, and existing tunnel lining end formwork often fails to meet these diverse needs. Finally, the cost is too high, installation and disassembly are inconvenient, the number of reuses is limited, and it is easily damaged. Utility Model Content

[0025] Example

[0026] like Figures 1 to 4 As shown, this utility model proposes a tunnel lining visualization end formwork device, including a tunnel wall 1 and a tunnel chamber 2 opened within the tunnel wall 1. It also includes: a compressible rubber block 3 attached to the top wall of the tunnel chamber 2. The compressible rubber block 3 is a sealing material used for tunnel lining and lining joints, widely used in tunnel engineering, especially for providing sealing for joints and connections in tunnel lining. Its main function is to fill the gaps between the tunnel structure and the lining, prevent water seepage, reduce wear on the tunnel lining, and maintain the structural stability and sealing of the tunnel wall; and a steel sealing plate 7, which has advantages such as compact structure, reliable protective performance, and quick conversion between peacetime and wartime use. The overall installation is time-saving and labor-saving, with good sealing effect, effectively enhancing the overall stability of the end formwork and effectively relieving longitudinal pressure on the concrete. Installed inside the tunnel chamber 2, corresponding vertically to the compressible rubber block 3; multiple raised pads 6 are arranged in a circular array in the middle of the steel sealing plate 7 and the compressible rubber block 3. The raised pads 6 have strong adaptability and structural stability, can adapt to various geological conditions, and can be adjusted according to different lining thicknesses, effectively improving on-site construction efficiency. Each raised pad 6 has an internal mounting groove 4 for the visual telescopic sealing plate 5 to be inserted into. The visual telescopic sealing plate 5 is made of a new type of high-polymer composite material, including polyurethane composite material, rubber composite material, and polytetrafluoroethylene composite material. It has high strength, visibility, and can be adjusted within a certain range, enhancing the adaptability of the end mold, effectively improving work efficiency, and saving costs. The visual telescopic sealing plate 5 displays the status of the sealing plate through some means (such as a display screen, indicator lights, monitoring system, etc.). For example, it can display in real time whether the sealing plate is completely closed or open, whether there is leakage, and whether there is a malfunction. This visual design helps operators remotely monitor and judge the working status of the equipment. Each of the heightening blocks 6 has a slot 61 at one end, and a locking head 62 that snaps into the corresponding slot 61 is fixedly connected to the end of each heightening block 6 away from the slot 61. The slot 61 and the locking head 62 can be quickly installed and removed. The end of each heightening block 6 near the bottom wall of the tunnel chamber 2 is cut off. This cut-off design ensures that multiple heightening blocks 6 can be tightly connected between the compressible rubber block 3 and the steel sealing plate 7, preventing shaking or gaps. Multiple heightening blocks 6 are connected as a whole by a visible telescopic sealing plate 5. The steel sealing plate 7 has multiple pairs of bolt mechanisms inside to fix the corresponding heightening blocks 6.

[0027] The design of tunnel lining end formwork must consider the specific shape and dimensions of the tunnel to ensure a tight fit between the formwork and the tunnel lining end section. The surrounding rock conditions must be considered during formwork fabrication to allow for adjustments and reuse. The entire formwork is constructed from lightweight, high-strength new composite materials, with on-site drawings used for fabrication and on-site assembly. Before installing the tunnel lining end formwork, the surface flatness of the initial tunnel support must be checked, and any excessively protruding areas should be removed. Simultaneously, circumferential and longitudinal drainage corrugated pipes must be installed, and a waterproof layer must be applied promptly. After assembly, a release agent must be applied. Finally, the installation of the tunnel lining end formwork must be strictly performed according to the procedures and the construction design drawings to ensure that the position, dimensions, and shape of the formwork meet design requirements. During pouring, the concrete mix ratio, pouring speed, and vibration intensity must be strictly controlled to ensure that the concrete fully fills the space within the formwork and reaches the designed strength. After pouring, curing work is required, such as spraying water and covering to keep it moist, to ensure that the concrete can harden properly and achieve the performance required by the design.

[0028] Furthermore, the bolt mechanism includes a groove 71 formed in the steel sealing plate 7. The groove 71 has multiple pairs of connecting holes 74 arranged in a circumferential array and corresponding to the raised pad 6. Each side of the raised pad 6 near the steel sealing plate 7 has a pair of bolt holes 63 corresponding to the connecting holes 74. Each pair of bolt holes 63 and connecting holes 74 is spirally connected with a second bolt 76. The end of the second bolt 76 abuts against the visual telescopic sealing plate 5 and can be adjusted within a certain range after abutting against the visual telescopic sealing plate 5 to meet the construction requirements of different sites.

[0029] Furthermore, a base plate 72 is fixedly connected to the bottom inner wall of the groove 71. Each base plate 72 has a pair of fixing holes 73. The inner bottom wall of the tunnel chamber 2 has multiple pairs of mounting holes 21 corresponding to the fixing holes 73. Each pair of mounting holes 21 and fixing holes 73 is bolted with a first bolt 75. The first bolt 75 fixes the base plate 72 to the inner bottom wall of the tunnel chamber 2, ensuring that the steel sealing plate 7 can be stably connected to the inner bottom wall of the tunnel chamber 2.

[0030] In this embodiment, when using the tunnel lining visualization end formwork device, specialized auxiliary tools and equipment, such as cranes and support frames, are required during installation to ensure that the tunnel lining end formwork can be accurately and stably installed at the tunnel end. Simultaneously, the formwork clips are tightened to prevent displacement or deformation of the tunnel lining end formwork during concrete pouring. After the tunnel lining end formwork is installed, the second bolt 76 is vertically installed along the steel sealing plate 7 and the heightening pad 6. The end of the second bolt 76 abuts against the elastic band of the visualization telescopic sealing plate 5, effectively adjusting the tightness of the heightening pad 6 against the compressible rubber block 3. This ensures a tight fit between the compressible rubber block 3 and the inner top wall of the tunnel chamber 2. Simultaneously, the visualization telescopic sealing plate 5 allows direct observation of the concrete flowability and pouring status, thus guaranteeing the overall quality of the lining.

[0031] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
