The top of the upper longitudinal beam 101 is provided with a vault hydraulic lifting and pouring device 6, and the lower sides of the upper longitudinal beam 101 are provided with columns 102. A jack 7 is provided on one side of the column 102, and a diagonal brace 103 is provided on the other side of the column 102. A walking support 8 is provided below the column 102. First, the main structural parts such as the upper longitudinal beam 101, the column 102 and the diagonal brace 103 are cut and welded according to the design requirements to form a trolley frame 1. Then, the vault hydraulic lifting and pouring device 6 is installed on the top of the upper longitudinal beam 101 to ensure that it can realize the lifting function. The design of the jack 7 and the walking support 8 allows the trolley to be adjusted and moved in height as needed to adapt to different construction environments and needs. The model of the arch hydraulic lifting and pouring device 6 used in the rapid pouring method is SC200 / 200TD. The arch hydraulic lifting and pouring device 6 generally includes a template assembly, a pouring pipe, a lifting drive, a rotation drive and a connecting mechanism.

[0037] Specifically, the formwork system 2 includes an arch formwork 201 and a side wall formwork 202. The arch formwork 201 is usually made of high-strength steel to ensure that it can withstand greater pressure without deformation during the concrete pouring process. Its surface needs to be specially treated to ensure that the appearance of the concrete is flat and smooth. The arch formwork 201 is connected to the top of the arch hydraulic lifting and pouring device 6, and the arch formwork 201 is connected to the trolley frame 1 through the arch hydraulic lifting and pouring device 6. The side wall formwork 202 is also made of high-strength steel and is connected to the jack 7 by bolts.

The side wall formwork 202 is provided with several groups, and each group of side wall formworks 202 is symmetrically arranged along the horizontal direction of the trolley frame 1. One side of the side wall formwork 202 is connected to the jack 7 by bolts, and the side wall formwork 202 is connected to the trolley frame 1 by the jack 7. In actual operation, the arch formwork 201 is first installed in place, and then fixed to the trolley frame 1 by the arch hydraulic lifting and pouring device 6. Next, the side wall formworks 202 are grouped according to the design requirements and arranged symmetrically on both sides of the trolley frame 1. Finally, each group of side wall formworks 202 is connected to the jack 7 using bolts, and further connected to the trolley frame 1 through the jack 7. This not only ensures the stability of the formwork system 2, but also facilitates subsequent pouring operations. The use of integral large-scale steel formworks instead of traditional bracket formwork technology significantly improves construction efficiency and quality. At the same time, since the formwork system 2 can be quickly assembled and disassembled, the construction period is greatly shortened.

The LED lamps 505 are arranged in several groups, and each group of LED lamps 505 is evenly arranged along the horizontal direction of the end mold plate 501.

[0041] Specifically, the end template 501 is made of high-strength steel and is formed by cutting, welding and other processes. The surface of the end template 501 needs to be treated with rust prevention, such as spraying anti-rust paint or galvanizing, to improve durability and corrosion resistance. A convex tooth 502 is provided on one side of the end template 501. The convex tooth 502 is made of wear-resistant material and is machined to ensure dimensional accuracy and surface finish. The design of the convex tooth 502 needs to consider the matching with the groove 503 to ensure the tightness and stability of the connection. The convex tooth 502 is provided in several groups, and each group of convex teeth 502 is evenly arranged along the horizontal direction of the end template 501. A groove 503 is provided on the side of the end template 501 away from the convex tooth 502. The groove 503 is a reserved position on the end template 501 and is formed through precision machining to ensure a perfect fit with the convex tooth 502. A lubricant can be applied inside the groove 503 to reduce friction resistance during installation. The groove 503 is provided in several groups, and each group of grooves 503 is evenly arranged along the horizontal direction of the end template 501. Bolt holes 504 are provided on both sides of the groove 503. The bolt holes 504 are According to the design requirements, holes are precisely drilled on the end template 501, and the hole diameter and position need to be strictly controlled to ensure the stability and strength of the bolt connection. An LED lamp 505 is arranged on the outer wall of the end template 501. The LED lamp 505 uses waterproof, dustproof, and high-brightness LED lamps, which are installed on the outer wall of the end template 501 and connected to the power supply through wires. The LED lamp 505 can be used for lighting or as an indicator mark during the construction process. There are several groups of LED lamps 505, and each group of LED lamps 505 is evenly arranged along the horizontal direction of the end template 501. Multiple end templates 501 are spliced ​​according to the requirements of the design drawings through the cooperation of convex teeth 502 and grooves 503. During the splicing process, it is necessary to ensure that the end templates 501 are tightly fitted without gaps. After the end template 501 is assembled, concrete is poured. During the pouring process, attention should be paid to controlling the fluidity and vibration effect of the concrete to ensure that the concrete is tightly combined with the template without voids and honeycomb phenomena.

[0042] Reference Figure 5 , Figure 6 and Figure 7The protruding teeth 502 and the grooves 503 have the same shape, and the end template 501 is assembled by connecting the protruding teeth 502 and the grooves 503 , and the protruding teeth 502 are fixed inside the grooves 503 by bolts through the bolt holes 504 .

[0043] Specifically, the shape of the protruding teeth 502 is consistent with that of the groove 503. The end template 501 is assembled by connecting the protruding teeth 502 and the groove 503. At the same time, the protruding teeth 502 are fixed to the inside of the groove 503 by bolts through the bolt holes 504. The matching connection of the protruding teeth 502 and the groove 503 provides an additional support point, thereby enhancing the overall stability of the template. This design can effectively prevent the template from displacement or deformation during the construction process. The protruding teeth 502 are fixed to the inside of the groove 503 through the bolt holes 504, further increasing the firmness of the connection, ensuring that the template remains stable when subjected to concrete pressure and other construction loads. The design of the protruding teeth 502 and the groove 503 makes the connection between the templates simpler and faster, reduces the installation time, and improves the construction efficiency. At the same time, due to the precise matching of the protruding teeth 502 and the groove 503, the close fit between the templates can be ensured, reducing the leakage of concrete during the concrete pouring process, thereby improving the construction quality of the concrete structure.

[0044] The implementation principle of the embodiment of the present application is as follows: the guide rail 3 is installed on the formwork system 2 of the trolley frame 1, and the inner wall of the tunnel is cleaned using the formwork annular cleaning device 4 to ensure that there is no obvious unevenness on the inner wall, and to ensure that the size and shape of the inner wall are consistent with the design drawings, and the error is controlled within the allowable range. After the cleaning is completed, on-site workers are arranged to check whether the surface of the inner wall meets the construction requirements. If necessary, secondary cleaning is performed. After the cleaning work of the formwork annular cleaning device 4 is completed, the on-site workers recycle the formwork annular cleaning device 4, and at the same time, the guide rail 3 in the formwork system 2 of the trolley frame 1 is dismantled and stored, the original state and installation method of the guide rail 3 are recorded, the prefabricated assembled end mold 5 is transported to the construction site, and the prefabricated assembled end mold 5 is transported according to the design requirements. Assemble the parts and select appropriate means of transport to ensure that the transport route is unobstructed. At the same time, use foam plastics, bubble film and other shock-proof materials to wrap the assembled end mold 5, and indicate the type, quantity, weight, size and other information of the module on the package. Use the arch hydraulic lifting and pouring device 6 to accurately control the concrete pouring position and pressure of the arch formwork 201. At the same time, use the jack 7 to control the concrete pouring position and pressure of the side wall formwork 202 to pour the concrete. Before pouring, adjust the position and angle of the arch hydraulic lifting and pouring device 6 through the console according to the construction drawings and actual conditions on site, start the hydraulic pump station, and send instructions through the console to make the lifting mechanism drive the formwork to slowly descend to the specified position to ensure accurate docking with the inner wall of the tunnel.

[0045] First, the trolley frame 1 is moved to the tunnel construction site, and the walking support 8 is fixed on the ground. Then, the arch hydraulic lifting and pouring device 6 is installed on the top of the upper longitudinal beam 101, and the arch template 201 is connected to the top of the arch hydraulic lifting and pouring device 6. Several groups of side wall templates 202 are symmetrically arranged along the horizontal direction of the trolley frame 1, and connected to the jack 7 by bolts. The jack 7 is used to adjust the position and angle of the side wall template 202. Before pouring concrete, the template needs to be cleaned to ensure that the concrete can flow into the template smoothly. At this time, the servo motor 402 is started, and the rotating base 403 is driven to rotate through the pulley 406, so that the brush head 404 cleans the surface of the template. At the same time, the dust suction fan 407 starts to work, and the dust generated during the cleaning process is sucked into the filter plate 405. When the template is cleaned, the concrete pouring starts. , the concrete is transported to the arch formwork 201 through the arch hydraulic lifting and pouring device 6, and the concrete is transported to the side walls on both sides of the tunnel through the side wall formwork 202. In this process, the position and angle of the side wall formwork 202 can be adjusted by the jack 7 to ensure that the concrete can be evenly distributed in the tunnel. After the concrete pouring is completed, the arch hydraulic lifting and pouring device 6 is stopped and the concrete is waited to solidify. During the concrete solidification period, the formwork annular cleaning device 4 can be used to clean and maintain the formwork. When the concrete is completely solidified, the arch formwork 201 and the side wall formwork 202 can be removed. At this time, the jack 7 can be used to remove the side wall formwork 202 from the tunnel side wall, and then the arch formwork 201 is removed from the arch hydraulic lifting and pouring device 6. Finally, the trolley frame 1 is moved out of the tunnel construction site to complete the entire construction process.

[0046] Align the end template 501 with the protruding teeth 502 with the other end template 501 with the grooves 503, ensure that each set of protruding teeth 502 is completely matched with the corresponding grooves 503, use bolts to fix the protruding teeth 502 inside the grooves 503 through the bolt holes 504, and ensure that all bolts are tightened in place to ensure the firmness and stability of the connection. A modular design is adopted, and the cooperation of the protruding teeth 502 and the grooves 503 can achieve fast and convenient assembly and disassembly. This design not only improves construction efficiency, but also facilitates maintenance and replacement.
