Description

Technical Field

[0001] The invention relates to the technical field of tunnel lining, in particular to a tunnel lining device. Background Art

[0002] Tunnel lining refers to a permanent structure that supports and maintains the long-term stability and durability of the tunnel. Its function is to support and maintain the stability of the tunnel; maintain the space required for train operation; prevent weathering of the surrounding rock; and eliminate the impact of groundwater. Therefore, the tunnel lining must have sufficient strength, durability, and certain anti-freeze, anti-seepage and anti-corrosion properties.

[0003] A Chinese invention patent with publication number CN117780391B discloses a tunnel lining trolley, comprising: a main pipeline is arranged on a material distribution ring seat and can rotate around the axis of the material distribution ring seat, the main pipeline includes a butt joint pipe section extending radially along the material distribution ring seat, a first pipe section is slidably sleeved on the butt joint pipe section, the second pipe section is connected to the first pipe section through a flexible pipe, a plurality of arc plates are arranged on the outer side of the flexible pipe, the arc plates connect the first pipe section and the second pipe section, a sleeve rope is sleeved on the outer peripheral surface of the flexible pipe, any two adjacent arc plates have ear plates, the ear plates are provided with through holes, the two rope ends of the sleeve rope pass through the two through holes respectively, a ring frame is slidably sleeved on the outer peripheral side of the flexible pipe, an elastic member is connected between the ring frame and the first pipe section, and the two rope ends of the sleeve rope are connected to the ring frame. In the process of separating the second pipe section from the grouting pipe of the present invention, the sleeve rope can tighten the flexible pipe in advance, thereby reducing the scattering of concrete, reducing the waste of resources and the burden of cleaning.

[0004] In addition, since the existing grouting methods are all injected through pipelines, when concrete is injected into the mold plate, it is necessary to manually climb to a high place to stir the concrete with a vibrator, which is not only cumbersome but also has the risk of falling, especially when the concrete on the top of the tunnel is stirred, which will cause the problem of concrete falling, thus affecting the concrete content required for the tunnel lining. At the same time, the manual stirring method has a limited action area, and the concrete at the corner cannot be stirred. Not only is the mixing degree not uniform, but also the larger particles inside the concrete sink, causing concrete stratification, which not only affects the adhesion between the concrete and the tunnel wall, but also affects the uniformity of the strength of the concrete after agglomeration. In addition, due to the complex structure of the inner wall of the tunnel, if the mold plate and the tunnel wall are not effectively separated during the movement of the lining vehicle, the mold will be worn. Therefore, the tunnel lining trolley disclosed in the Chinese invention patent CN117780391B cannot avoid the uniformity of concrete stratification and the strength of concrete after agglomeration, nor can it guarantee the service life of the mold plate.

On the outer wall of the top template 47 and the outer wall of the side template 48, arc baffles 59 are symmetrically fixedly connected, and the end of the driving rod 51 close to the fixed plate four 54 rotates inside the arc baffle 59, and the outer wall of the arc baffle 59 is arranged in a ring array and is limitedly rotatably connected with a circular ring plate 58, and the interior of the arc baffle 59 is arranged in a ring array with a slide groove 510, and the size of the rectangular rod two 56 is adapted to the size of the slide groove 510, and the interior of the slide groove 510 is symmetrically provided with a card groove 511, and the size of the card groove 511 is adapted to the size of the rectangular rod one 55. By setting the driving rod 51, the threaded rod 53 is used to stir the concrete, and the threaded rod 5 can be automatically stored.

[0040] The following is the working process and principle of the above embodiment:

[0041] The initial state is as follows: the hydraulic rod 33 is in an unextended state, the telescopic rod 38 is in an unextended state, the spring 310 is in an unstretched state, the top template 47 and the side template 48 are in an unaggregated state, and the threaded rod 53 is inside the driving rod 51.

[0042] The working steps are as follows:

[0043] When the device moves to the position where the tunnel needs to be constructed, the operator uses the external control device to control the driver 32 to control the hydraulic rod 33 to start extending vertically upward, so that the hydraulic rod 33 drives the hinge block 1 34 to extend upward synchronously, and the hinge block 1 34 drives the fixed plate 2 35 to move synchronously, and the fixed plate 2 35 drives the bottom end of the bracket 36 to move synchronously, so that the bracket 36 drives the telescopic end of the telescopic rod 38 to extend vertically upward through the baffle 1 37, and stretches the spring 310.

[0044] In the process of the bracket 36 moving vertically upward, the bracket 36 drives the guardrail plate 41 to move vertically upward synchronously, and the guardrail plate 41 drives the fixed plate three 42 and the support plate 45 to move vertically upward synchronously, so that the support plate 45 drives the top template 47 to move toward the top of the tunnel wall through the elastic expansion plate 46, and the top template 47 drives the side template 48 to move vertically upward synchronously through the rotating shaft rod 49. When the top template 47 contacts the tunnel wall and the bracket 36 continues to move upward, the elastic expansion plate 46 shrinks inwardly under the contact of the top template 47, and at the same time, the fixed plate three 42 drives the contact rod 43 connected to it to move synchronously, so as to The abutment rod 43 abuts against the side template 48 through the hinge block 44, so that the side template 48 begins to flip toward the side close to the tunnel wall with the rotating shaft rod 49 as the axis, until the side template 48 flips to the position where it is aggregated with the top template 47 and stops flipping. At this time, the side template 48 moves to a position in contact with the tunnel side wall, and the bracket 36 stops moving vertically upward. The degree of aggregation of the side template 48 and the top template 47 is controlled by adjusting the extension height of the bracket 36, thereby preventing the equipment from being worn and collided during movement inside the tunnel, avoiding gaps in the mold grooves set in the top template 47 and the side template 48, further avoiding the problem of liquid leakage in the mold groove, and improving the service life of the mold.

[0045] Then the operator starts to put concrete into the mold grooves provided on the outer walls of the side formwork 48 and the top formwork 47 through the pipeline. The operator controls the driving rod 51 to start rotating clockwise on the outer walls of the top formwork 47 and the side formwork 48 through the external control device. Since the threaded rod 53 is inside the driving rod 51 at the beginning of the work, the rectangular rod 1 55 is inside the card groove 511 and cannot rotate. Therefore, during the rotation of the driving rod 51, the driving rod 51 drives the threaded groove 52 to rotate synchronously, so that the threaded groove 52 drives the threaded rod 53 to start moving to the side away from the threaded groove 52, so that the threaded rod 53 drives the fixing plate 4 54 to move to the side away from the arc baffle 59, so that the fixing plate 4 54 drives the rectangular rod 1 55 to slide on the outer wall of the rectangular rod 2 56 to the side away from the limiting circular plate 1 57. When the end of the threaded rod 53 close to the limiting circular plate 1 57 moves to the end of the driving rod 51 away from the limiting circular plate 1 57, the threaded rod 5 3 cannot be extended, and at the same time, the threaded rod 53 drives the rectangular rod 1 55 to move to the side away from the limiting circular plate 1 57 through the fixing plate 4 54 until the rectangular rod 1 55 no longer conflicts with the position of the clamping groove 511, so that the threaded rod 53 starts to rotate synchronously under the conflicting effect of the thread groove 52, so that the threaded rod 53 drives the fixing plate 4 54 to rotate synchronously, so that the fixing plate 4 54 drives the rectangular rod 1 55 to rotate synchronously, so that the rectangular rod 1 55 conflicts with the annular plate 58 and rotates synchronously on the outer wall of the arc baffle 59, so that the rectangular rod 1 55 drives the limiting circular plate 1 57 to rotate synchronously on the outer wall of the top template 47 through the rectangular rod 2 56, and the concrete is driven to move repeatedly in the mold groove through the rotation of the threaded rod 53, thereby avoiding the stratification of the static concrete in the mold groove, and the concrete is stirred during the movement by the rectangular rod 1 55, thereby improving the uniformity of the concrete after mixing and ensuring the protective strength of the concrete after agglomeration.

[0046] When the threaded rod 53 finishes mixing the concrete, the driving rod 51 starts to rotate counterclockwise, so that the threaded rod 53 moves toward the inside of the driving rod 51 under the interference of the threaded groove 52, so that the threaded rod 53 drives the rectangular rod 55 to move toward the side close to the limiting circular plate 57 through the fixing plate 454, so that the rectangular rod 55 moves toward the side close to the limiting circular plate 57 through the card slot 511 opened in the slide slot 510, until the rectangular rod 55 completely enters the inside of the driving rod 51, at this time the driving rod 51 stops rotating, and then the operator fills a small amount of concrete into the top template 47 and the side template 48 again until the concrete agglomeration work is completed, and the concrete is mixed by the threaded rod with a storage function, avoiding manual climbing to a high place to mix the concrete with a vibrating rod, which not only reduces the risk factor of the construction workers, but also improves the work efficiency of the tunnel lining.
