[0032] like Figures 1 to 3 As shown, a pair of spring rods 5 are slidably connected to the middle of the beam frame 11; the end of the spring rod 5 is fixedly connected to the second roller 51; the spring rod 5 and the second roller 51 are close to the top of the beam frame 11 and face the side template 110; during operation, when the hydraulic jack retracts the side template 110, the inner wall of the side template 110 will contact the second roller 51, and at this time the side template 110 will squeeze the spring rod 5 to produce stretching, thereby generating a buffering force, and when the winch 111 moves, the second roller 51 will rotate on the surface of the winch 111. Through the above structure, the arrangement of the spring rod 5 and the second roller 51 can reduce the impact force generated between the winch 111 and the beam frame 11 when the winch 111 is gathered, resulting in damage and bending, thereby playing a buffering role.

[0033] like Figure 1 to Figure 2 As shown, the inner walls of the upper formwork 18, the lower formwork 19 and the side formwork 110 are fixedly connected with a plurality of vibration motors 6; the plurality of vibration motors 6 are evenly distributed structures; when working, when pouring concrete into the tunnel from the pouring port 114, the plurality of vibration motors 6 are started to generate vibration, and at this time, the vibration is transmitted to the interior of the concrete through the upper formwork 18, the lower formwork 19 and the side formwork 110, and at this time, the concrete can be vibrated, thereby vibrating away some bubbles between the concrete. Through the above structure, the vibration motor 6 can be set to drive the poured concrete to vibrate, so as to reduce the bubbles between the concrete, thereby making the connection between the concrete tighter, so as to improve the solidification effect of the concrete.

[0034] like Figure 1 As shown, a plurality of anchor rods 7 are fixedly connected to the bottom of the first support plate 33; the bottom of the anchor rods 7 is a vertebral structure; when working, after the second hydraulic cylinder 32 drives the first support plate 33 to contact the bottom surface of the tunnel, the anchor rods 7 at the bottom of the first support plate 33 will be inserted into the soil layer of the tunnel. Through the above structure, the anchor rods 7 are arranged to connect the first support plate 33, and the anchor rods 7 can be inserted into the soil layer of the tunnel to improve the stability of the position of the first support plate 33, so as to reduce the situation where the first support plate 33 slides and causes overall displacement.

[0035] like Figure 5 As shown, a feed hopper 8 is fixedly connected to the top of the oil storage box 14; the feed hopper 8 is arranged corresponding to the feed port at the top of the oil storage box 14; a sealing plug 81 is slidably fitted in the feed hopper 8; during operation, when it is necessary to add lubricant to the oil storage box 14, the sealing plug 81 can be taken out from the feed hopper 8, and then the lubricant is added to the feed hopper 8, and then enters the oil storage box 14 along the feed port at the top of the oil storage box 14, and then the sealing plug 81 is reset to the feed hopper 8.

[0036] like Figure 1 and Figure 2 As shown, the side wall of the support block 31 is provided with a plurality of square grooves 9; through the above structure, the provision of the square grooves 9 can reduce the overall weight of the support block 31, thereby achieving a lightweight effect.

[0037] Working principle: After the beam body 1 and the beam frame 11 are installed, the slider 13 and the first roller 115 are located inside the slide rail 12, and then the upper template 18, the lower template 19 and the side template 110 are connected to the beam frame 11 through the hydraulic jack. During construction, the upper template 18, the lower template 19 and the side template 110 are spread apart by the hydraulic jack so as to be close to the inner surface of the tunnel, and then the concrete is pumped to the tunnel and the upper template 18, the lower template 19 and the side template 110 through the pouring port 114. After the concrete solidifies, the upper template 18, the lower template 19 and the side template 110 are gathered together by the hydraulic jack, and then the winch 111 cooperates with the pulley 112 and the steel cable 113 to make the beam frame 11 slide on the beam body 1. At this time, the slider 13 drives the first roller The wheel 115 slides in the slide rail 12. When the first roller 115 passes the oil storage box 14 at the top of the slide rail 12, the push rod 17 and the cover plate 16 will be pushed upward. At this time, the lubricant stored in the oil storage box 14 will flow from the oil outlet below the oil storage box 14 to the first roller 115 and the slider 13 for lubrication. After the first roller 115 passes the oil storage box 14, the spring telescopic rod 15 will rebound to reset the push rod 17 and the cover plate 16, so that the cover plate 16 covers the oil outlet below the oil storage box 14. When it is necessary to move the beam 1, the upper template 18, the lower template 19 and the side template 110 are supported in a state of being spread apart, and then the supporting assembly on the beam 1 is retracted, and then the winch 111, the pulley 112 and the steel cable 113 drive the beam 1 to move. During the construction process such as the movement of the beam frame 11 and the pouring of concrete, more vibrations will be generated. When the vibration is transmitted to the damping spring shock absorber 2 under the beam body 1, the damping spring shock absorber 2 will perform buffering and vibration reduction through its own contraction and rebound. When installing the first hydraulic cylinder 3 and the support block 31, the first hydraulic cylinder 3 and the support block 31 are installed at the end where the tunnel concrete is laid, and the second hydraulic cylinder 32 and the first support plate 33 are installed at the end to be laid.

At this time, the arc surface of the support block 31 will contact with the arc surface of the concrete, and the second hydraulic cylinder 32 will stretch and drive the first support plate 33 to contact with the surface to be laid in the tunnel. At this time, the beam body can be 1 is supported by the beam frame 11, and then subsequent pouring and other work are carried out. After the beam body 1 moves to the construction position, the third hydraulic cylinder 4 is started to drive the second support plate 41 to move toward the bottom surface of the tunnel. When the second support plate 41 contacts the bottom surface of the tunnel, it will support from the middle section of the beam body 1. When the hydraulic jack retracts the side template 110, the inner wall of the side template 110 will contact the second roller 51. At this time, the side template 110 will squeeze the spring rod 5 to generate tension, thereby generating a buffering force. When the winch 111 moves, the second roller 51 will rotate on the surface of the winch 111. When pouring concrete into the tunnel from the pouring port 114, multiple vibration motors 6 are started to generate vibration. At this time, the vibration passes through the upper template 18, the lower template 19 and the side template 110.The conduction to the inside of the concrete can generate vibrations on the concrete, thereby vibrating away some of the bubbles between the concrete. After the second hydraulic cylinder 32 drives the first support plate 33 to contact the bottom surface of the tunnel, the anchor rod 7 at the bottom of the first support plate 33 will be inserted into the soil layer of the tunnel. When it is necessary to add lubricant to the oil storage box 14, the sealing plug 81 can be taken out of the feed hopper 8, and then the lubricant is added to the feed hopper 8, and then enters the oil storage box 14 along the feed port at the top of the oil storage box 14, and then the sealing plug 81 is reset to the feed hopper 8.
