[0013] In a possible implementation, a transverse steel bar positioning plate is longitudinally connected to the outer ends of the middle platform and the bottom platform on the same side, and a plurality of transverse steel bar positioning grooves are arranged at equal intervals along the length direction of the outer end of the transverse steel bar positioning plate.

[0014] The beneficial effect of a tunnel side wall steel bar binding jig trolley provided by the present invention is that: compared with the prior art, a plurality of universal running wheels are configured at the bottom of the gantry, which enables the entire jig trolley to have flexible horizontal and vertical movement capabilities, and can conveniently adjust the position as needed in the tunnel side wall construction area, adapt to the operation requirements of different construction sections, and improve the mobility and use efficiency of the equipment. The entire jig trolley moves to the side wall position on one side of the tunnel, and the top platform close to the side wall can realize the switching between the horizontal working state and the vertical avoidance state under the drive of the lifting drive mechanism. First, when the top platform is in the horizontal working state, the operator lays the waterproof board on the top platform, and then switches the top platform to the vertical avoidance state, and hoists the steel bars to be bound to the middle platform and the bottom platform. The operators on the middle platform and the bottom platform complete the binding operation of the side wall steel bars on the same side.

Finally, the jig trolley is moved as a whole along the length direction of the tunnel, and finally the binding operation of all waterproof panels and steel bars in the depth direction of the tunnel is completed. Compared with the traditional steel bar binding trolley, the jig trolley for binding the side wall of the tunnel provided by the present invention can quickly complete the construction of the tunnel without repeated disassembly and assembly, thereby ensuring the overall progress of the tunnel construction.

[0015] The present invention also provides a tunnel side wall steel bar binding construction process, using the tunnel side wall steel bar binding jig trolley, comprising the following steps: S1: The gantry moves horizontally to the side wall position of one side of the tunnel through multiple universal running wheels, and the lifting cylinder is started.

The lower end of the lifting cylinder retracts and the lower ends of the multiple steel legs press the wooden board; S2: Use a truck crane to lift the waterproof sheet roll to the top platform in a horizontal working state, remove the rotating roller, put the waterproof sheet roll on the rotating roller, and then place the rotating roller together with the waterproof sheet roll at the outer end of the top platform. The waterproof sheet roll rotates with the rotating roller and is laid on the side wall in sequence; S3: Remove the protective fence of the top platform, use the sling of the electric hoist to pull the top platform to a vertical avoidance state, and use the truck crane to lift the steel bars to be tied to the steel bar storage area of ​​the middle platform and the lower crossbeam on the inner side of the bottom platform; S4: The workers in the cantilevered working area of ​​the middle platform and the bottom platform use the multiple vertical steel bar positioning grooves on the vertical steel bar positioning plate to transversely tie multiple steel bars, and use the multiple transverse steel bar positioning grooves on the transverse steel bar positioning plate to vertically tie multiple steel bars; S5: Start the lifting cylinder, the lower end of the lifting cylinder supports the ground and gradually extends until the multiple steel legs leave the wooden board, the wooden board under the steel legs is removed, the lower end of the lifting cylinder retracts and the lower ends of the multiple universal running wheels are pressed against the ground; S6: The gantry moves laterally to the side wall position on the other side of the tunnel through a plurality of universal running wheels, and steps S2-S5 are repeated; S7: The gantry moves to the next area along the length direction of the tunnel through a plurality of universal running wheels, and steps S1-S6 are repeated until the binding operation of all the steel bars in the tunnel is completed.

[0023] See also Figure 1 Now, a tunnel side wall steel bar binding jig trolley provided by the present invention is described. A tunnel side wall steel bar binding jig trolley comprises a gantry 1, a plurality of universal running wheels 2 are arranged at the bottom of the gantry 1, a top platform 6, a middle platform 7 and a bottom platform 8 are symmetrically arranged on both sides of the gantry 1, and the top platform 6, the middle platform 7 and the bottom platform 8 on the same side are arranged in sequence from top to bottom; an inner end of the top platform 6 is hingedly arranged on the gantry 1, and lifting drive mechanisms are respectively arranged on both sides of the top of the gantry 1, and the lifting drive mechanisms are used to drive the top platform 6 to rotate to a horizontal working state or a vertical avoidance state with its inner end as a rotation axis. The top platform 6 in the horizontal working state is used to provide a platform for laying waterproof boards, and the top platform 6 in the vertical avoidance state is used to avoid steel bars to reach the middle platform 7; the middle platform 7 is horizontally arranged and an inner end of the middle platform 7 is fixedly arranged on the gantry 1, the bottom platform 8 is horizontally arranged and an inner end of the bottom platform 8 is fixedly arranged on the gantry 1, and the middle platform 7 and the bottom platform 8 are used to provide a platform for steel bar binding operations.

[0024] The present invention provides a tunnel side wall steel bar binding jig trolley. Compared with the prior art, the bottom of the gantry 1 is equipped with multiple universal running wheels 2, which enables the entire jig trolley to have flexible horizontal and vertical movement capabilities, and can easily adjust the position as needed in the tunnel side wall construction area to adapt to the operation requirements of different construction sections, thereby improving the mobility and use efficiency of the equipment. The entire jig trolley moves to the side wall position on one side of the tunnel, and the top platform 6 close to the side wall can be driven by the lifting drive mechanism to switch between the horizontal working state and the vertical avoidance state. First, when the top platform 6 is in the horizontal working state, the operator lays the waterproof board on the top platform 6, and then switches the top platform 6 to the vertical avoidance state, and hoists the steel bars to be tied to the middle platform 7 and the bottom platform 8. The operators located on the middle platform 7 and the bottom platform 8 complete the binding operation of the side wall steel bars on the same side. The jig trolley is moved to the side wall position on the other side as a whole, and the above operation is repeated to complete the binding operation of the side wall waterproof board and steel bars on the other side. Finally, the jig trolley is moved as a whole along the length direction of the tunnel, and finally the binding operation of all waterproof panels and steel bars in the depth direction of the tunnel is completed. Compared with the traditional steel bar binding trolley, the jig trolley for binding the side wall of the tunnel provided by the present invention can quickly complete the construction of the tunnel without repeated disassembly and assembly, thereby ensuring the overall progress of the tunnel construction.

[0025] See also Figure 1 , the top platform 6, the middle platform 7 and the upper end surface of the top platform 6 are all provided with protective fences 9 in the circumference, and the protective fences 9 located on the top platform 6 are detachably connected. The three platforms are all provided with protective fences 9, which can guarantee the personal safety of the construction personnel when working on each platform as a whole. Whether it is for routine operations such as laying waterproof boards and tying steel bars, or for short stays on the platform, carrying small tools, etc., the protective fences 9 can prevent personnel from falling from the edge of the platform due to accidental slips, collisions, etc., and reduce the probability of safety accidents. After the laying of the waterproof board is completed, the top platform 6 needs to be rotated to a vertical avoidance state. Therefore, the protective fence 9 of the top platform 6 needs to be detachably connected, and the protective fence 9 on it needs to be removed before rotating the top platform 6. When the waterproof board needs to be laid again, the top platform 6 is rotated to a horizontal working state and the protective fence 9 is installed.

[0026] Specifically, a rotating roller 10 is detachably provided at one end of the outer side of the top platform 6, and the rotating roller 10 is used to install the waterproof sheet roll and unfold the waterproof sheet with rotation. The rotating roller 10 has a specific function, which is mainly used to place the waterproof sheet roll, and can drive the waterproof sheet to unfold by its own rotation, thereby realizing the operation of laying the waterproof sheet on the tunnel side wall. This design provides a convenient and efficient way for the waterproof sheet laying operation. The traditional waterproof sheet laying method requires manual unfolding of the waterproof sheet little by little, which is not only inefficient, but also prone to problems such as wrinkles and uneven laying of the waterproof sheet. By arranging the rotating roller 10 at one end of the outer side of the top platform 6 and unfolding the waterproof sheet by its rotation, a relatively uniform and smooth laying process can be achieved, which greatly improves the laying efficiency, and at the same time ensures the flatness and fit of the waterproof sheet laying, which helps to improve the waterproof effect. In the past, manual handling and unfolding of the waterproof sheet often required the cooperation of multiple people, but with the automatic unfolding function of the rotating roller 10, the dependence on the number of manpower is reduced to a certain extent, saving labor costs. The construction personnel only need to control the key links such as the direction and position of the waterproof sheet laying.

[0027] The lifting drive mechanism includes an electric hoist 11 installed on one side of the top of the gantry 1, and the sling of the electric hoist 11 is connected to the middle of the top platform 6. When laying waterproof panels, the electric hoist 11 can rotate the top platform 6 to a horizontal working state by releasing the sling, creating a suitable operating plane for construction workers; and when it is necessary to avoid steel bars in order to reach the middle platform 7 to carry out related operations, the electric hoist 11 will retract the sling and drive the top platform 6 to rotate to a vertical avoidance state. The operation is convenient and efficient, which well meets the actual needs of different stages of tunnel side wall construction.

[0028] Specifically, a triangular support frame 12 is fixed in the middle of the left and right sides of the gantry 1, and a steel bar storage area and a cantilevered operation area are sequentially arranged on the middle platform 7 from the direction close to the gantry 1 to the direction away from the gantry 1, and the steel bar storage area is arranged above the triangular support frame 12. The triangular support frame 12 includes a steel bracket composed of a plurality of main bodies and a plurality of oblique legs welded together, and a plurality of I-beams are laid flat on the upper end of the steel bracket, and a thin steel plate with a pattern is laid on the I-beam, and this area forms a steel bar storage area, while the outer side forms a cantilevered operation area, which can be closer to the side wall position and is convenient for laying steel bars.

[0029] Among them, the setting of the steel bar storage area provides a special placement area for the steel bars used in the construction process, which is convenient for construction workers to classify, store and use the steel bars. For example, they can be placed in different areas according to the specifications and models of the steel bars, so that they can quickly and accurately find the corresponding steel bars when they need to be tied, thereby improving construction efficiency. The cantilevered work area provides a suitable space for construction workers to perform operations such as steel bar tying. Especially when handling steel bars near the edge of the tunnel side wall, construction workers can stand in the cantilevered work area to better stretch their arms, operate tools, complete the tying action, and ensure the firmness and accuracy of the steel bar tying.

[0030] Specifically, two lower cross beams 3 are arranged at the lower part of the gantry 1, and a plurality of universal running wheels 2 are symmetrically arranged at the lower ends of the two lower cross beams 3, and a bottom platform 8 is horizontally arranged at the same end of the two lower cross beams 3 and away from the side of the gantry 1. The arrangement of the two lower cross beams 3 enhances the stability of the entire trolley structure. They can evenly share the various loads (such as the weight of personnel, tools, steel bars, etc.) borne by the multiple universal running wheels 2 from the trolley itself and during the construction process, avoiding the situation where the running wheels are damaged or their walking function is affected due to excessive force at a single point, and ensuring that the trolley remains stable and reliable during movement. The bottom platform 8 is located on the side of the two lower cross beams 3 away from the gantry 1. Such a position design allows construction personnel to have a wider operating field of vision when tying steel bars, and can better observe and handle the steel bars in the entire tunnel side wall construction area. At the same time, being away from the gantry 1 also avoids the inconvenience of collision, interference, etc. caused by being too close to the gantry 1 structure during the construction process, and creates a relatively independent and spacious working space for the construction personnel, which is convenient for carrying out various binding actions and using corresponding construction tools.

[0031] Preferably, a lifting cylinder 4 is provided in the middle of the lower cross beam 3, and steel legs 5 are provided on both sides of the lower end surface of the lower cross beam 3. When the entire jig trolley needs to be positioned, the lifting cylinder 4 is started, the lower end of the lifting cylinder 4 supports the ground and gradually extends until the multiple universal running wheels 2 and the multiple steel legs 5 leave the ground, and the wooden board is placed under the steel legs 5, and the lower end of the lifting cylinder 4 retracts and the lower ends of the multiple steel legs 5 press the wooden board. When the entire jig trolley needs to be moved, the lifting cylinder 4 is started, the lower end of the lifting cylinder 4 supports the ground and gradually extends until the multiple steel legs 5 leave the wooden board, and the wooden board under the steel legs 5 is removed, and the lower end of the lifting cylinder 4 retracts and the lower ends of the multiple universal running wheels 2 press the ground.

[0032] See also Figure 2 and Figure 3, a vertical steel bar positioning plate 13 is horizontally arranged at one end of the outer side of the middle platform 7 and the bottom platform 8, and a plurality of vertical steel bar positioning grooves 14 are evenly spaced at one end of the outer side of the vertical steel bar positioning plate 13 along its length direction. The vertical steel bar positioning plate 13 is horizontally welded to one end of the outer side of the middle platform 7 and the bottom platform 8, and a transverse steel bar positioning plate 15 is longitudinally connected to one end of the outer side of the middle platform 7 and the bottom platform 8 on the same side, and a plurality of transverse steel bar positioning grooves 16 are evenly spaced at one end of the outer side of the transverse steel bar positioning plate 15 along its length direction. The equal spacing of the vertical steel bar positioning grooves 14 and the transverse steel bar positioning grooves 16 enables construction personnel to accurately place the vertical and transverse steel bars in place according to the positions of the positioning grooves when placing the steel bars, ensuring that each steel bar is in the correct position designed in advance before being tied, avoiding the position deviation problem that may occur when placing the steel bars manually based on experience, thereby laying a solid foundation for creating a high-quality tunnel side wall steel bar structure that meets the design standards. With these positioning plates and positioning grooves, construction workers do not need to spend a lot of time repeatedly measuring and adjusting the position of the steel bars. They only need to put the steel bars into the corresponding positioning grooves to start the binding work, which greatly saves the time spent on the steel bar positioning link, thereby improving the efficiency of the entire steel bar binding operation and speeding up the overall progress of the tunnel side wall construction.

[0033] See also Figure 4 and Figure 5 The present invention also provides a tunnel side wall reinforcement binding construction process, using the above-mentioned tunnel side wall reinforcement binding jig trolley, comprising the following steps: S1: The gantry 1 is laterally moved to the side wall position of one side of the tunnel through the multiple universal running wheels 2, and the jacking cylinder 4 is started. The lower end of the jacking cylinder 4 supports the ground and gradually extends until the multiple universal running wheels 2 and the multiple steel legs 5 leave the ground, and the wooden board is placed under the steel legs 5. The lower end of the jacking cylinder 4 retracts and the lower ends of the multiple steel legs 5 press the wooden board tightly; S2: Use a car crane to lift the waterproof sheet roll to the top platform 6 in a horizontal working state, remove the rotating roller 10, and then put the waterproof sheet roll on the rotating roller 10, and then place the rotating roller 10 together with the waterproof sheet roll at the outer end of the top platform 6. The waterproof sheet roll rotates with the rotating roller 10 and is laid on the side wall in sequence; S3: Remove the protective fence 9 of the top platform 6, use the sling of the electric hoist 11 to pull the top platform 6 to a vertical avoidance state, and use the truck crane to lift the steel bars to be tied to the steel bar storage area of ​​the middle platform 7 and the lower crossbeam 3 on the inner side of the bottom platform 8; S4: The workers located on the cantilevered working area of ​​the middle platform 7 and the bottom platform 8 use the multiple vertical steel bar positioning grooves 14 on the vertical steel bar positioning plate 13 to transversely tie multiple steel bars, and use the multiple transverse steel bar positioning grooves 16 on the transverse steel bar positioning plate 15 to vertically tie multiple steel bars; S5: Start the lifting cylinder 4, the lower end of the lifting cylinder 4 supports the ground and gradually extends until the multiple steel legs 5 leave the wooden board, the wooden board under the steel legs 5 is taken away, and the lower end of the lifting cylinder 4 retracts and makes the lower ends of the multiple universal running wheels 2 press against the ground; S6: The gantry 1 moves laterally to the side wall position on the other side of the tunnel through the multiple universal running wheels 2, and steps S2-S5 are repeated; S7: The gantry 1 moves to the next area along the length direction of the tunnel through a plurality of universal running wheels 2, and steps S1-S6 are repeated until the binding operation of all the steel bars in the tunnel is completed.

[0034] The present invention also provides a tunnel side wall reinforcement binding construction process, and the specific operation steps are as follows: First, make preliminary preparations for construction and put the trolley into position. By manipulating the multiple universal running wheels 2 at the bottom of the gantry 1, it moves in the lateral direction and accurately reaches the location of the side wall on one side of the tunnel. Then, start the key component of the jacking cylinder 4. The lower end of the jacking cylinder 4 is firmly supported on the ground and begins to gradually extend. During this process, the multiple universal running wheels 2 and the multiple steel legs 5 will slowly leave the ground. At this time, the construction workers carefully place the prepared wooden boards under the steel legs 5, and then control the lower end of the jacking cylinder 4 to retract, so that the lower ends of the multiple steel legs 5 can tightly press the wooden boards. In this way, the trolley is firmly placed in the current position, laying a solid foundation for subsequent construction operations.

[0035] The next step is to lay the waterproof sheet. Using the powerful lifting tool, the waterproof sheet roll is smoothly lifted to the top platform 6 in a horizontal working state. Then, the rotating roller 10 is carefully removed, the waterproof sheet roll is carefully placed on the rotating roller 10, and the assembled rotating roller 10 and the waterproof sheet roll are placed together at the outer end of the top platform 6. With the preparations ready, the waterproof sheet roll will be laid on the side wall of the tunnel in an orderly manner under the rotation of the rotating roller 10, creating a good waterproof foundation for the subsequent steel bar binding work.

[0036] After the waterproofing board is laid, it is time to start the related operations of lifting the steel bars and adjusting the state of the top platform 6. First, remove the protective fence 9 of the top platform 6, then start the electric hoist 11, use the lifting rope of the electric hoist 11 to apply tension, and slowly pull the top platform 6 to a vertical avoidance state to make room. Then, with the help of the powerful lifting capacity of the truck crane, the steel bars to be tied are accurately lifted to the steel bar storage area of ​​the middle platform 7 and the lower crossbeam 3 on the inner side of the bottom platform 8, preparing the required materials for the steel bar tying operation.

[0037] Entering the steel bar binding stage, the workers on the cantilevered working area of ​​the middle platform 7 and the bottom platform 8 each performed their duties. They used the multiple vertical steel bar positioning grooves 14 carefully set on the vertical steel bar positioning plate 13 as a reference and skillfully tied multiple steel bars horizontally. At the same time, they also tied multiple steel bars vertically in an orderly manner based on the multiple horizontal steel bar positioning grooves 16 that were also evenly spaced on the horizontal steel bar positioning plate 15. Through such precise positioning and binding operations, the stability and accuracy of the steel bar structure are ensured, providing guarantee for the quality of the tunnel side wall.

[0038] After the steel bar binding work on one side wall is completed, the trolley needs to be moved to facilitate construction in other areas. The lifting cylinder 4 is started again, so that its lower end supports the ground and gradually extends until the multiple steel legs 5 leave the wooden board below, and then the wooden board below the steel legs 5 is removed, and then the lower end of the lifting cylinder 4 is controlled to retract, so that the lower ends of the multiple universal running wheels 2 are pressed against the ground again. In this way, the trolley can move flexibly again relying on the universal running wheels 2.

[0039] At this time, the gantry 1 moves laterally to the side wall position on the other side of the tunnel through multiple universal running wheels 2, and then repeats the above steps S2 to S5, and completes the waterproofing board laying, steel bar lifting and binding of the other side wall according to the same process.

[0040] Finally, the gantry 1 will move to the next construction area along the length of the tunnel through multiple universal running wheels 2, and repeat all the operations from steps S1 to S6 again, and repeat this cycle until the binding operations of all areas and all steel bars in all areas of the tunnel are successfully completed, contributing to the steady progress of the construction of the entire tunnel project.

[0041] The beneficial effect of a tunnel side wall steel bar binding construction process provided by the present invention is that, compared with the prior art, since the construction process uses the above-mentioned tunnel side wall steel bar binding jig trolley, it has the same beneficial effect as the tunnel side wall steel bar binding jig trolley, which will not be repeated here.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
