[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present application discloses a non-excavation thin film system for repair, and its application environment includes but is not limited to underground buildings, tunnels, and bridge bottom plates. Figure 1 and Figure 2The thin film system for trenchless repair includes a film plate 1, a bin 2, a longitudinal conveying device 3, a transverse conveying device 4 and a grouting channel 5. The surface of the film plate 1 is provided with a guide groove for transmitting the film coating, wherein the film coating includes but is not limited to polyurethane waterproof coating, cement-based penetrating crystallization waterproof coating or epoxy resin waterproof coating. The guide groove is provided at the edge of the film plate 1 with a guide interface 17 connected to the guide grooves of other film plates 1; the film plate 1 adopts a plate with a smaller thickness and a harder material, including but not limited to a steel plate or a high-rigidity fiberboard, with a thickness range of 4-10mm. In the case of meeting the need to open a guide groove, the smaller the thickness of the plate, the better, so that the film plate 1 can be easily inserted into the soil. The bin 2 is cylindrical, and both the top and the bottom are open. By opening a construction groove at the position to be repaired, the bin 2 is partially inserted into the construction groove from the building interior, and the top of the bin 2 is set toward the building interior. The longitudinal conveying device 3 is arranged inside the silo 2, and is used to convey the film-coated board 1 from the top of the silo 2 to the bottom of the silo 2, so that the transverse conveying device 4 can receive the film-coated board 1. The transverse conveying device 4 is located at the bottom of the construction groove, that is, located on the side of the silo 2 close to the bottom, and a conveying interval for conveying the film-coated board 1 is provided between the silo 2 and the silo 2, and the film-coated board 1 is laid in contact with the outer wall of the building through the conveying interval. The grouting channel 5 is arranged inside the silo 2, and a plurality of grouting channels 5 are provided. One end of the grouting channel 5 is connected to the film coating supply equipment, and the other end leads to the conveying interval to guide the film coating to the film-coated board 1.

[0031] When repairing the waterproof layer, a construction groove is opened near the position to be repaired, and the diameter of the construction groove is the same as the diameter of the warehouse body 2. The horizontal conveying device 4 and the warehouse body 2 are installed in the construction groove, and multiple film-covered boards 1 are sent to the longitudinal conveying device 3 for transmission manually or mechanically in turn. The longitudinal conveying device 3 intermittently conveys the film-covered boards 1 from the top of the warehouse body 2 to the bottom of the warehouse body 2. The horizontal conveying device 4 receives the film-covered boards 1 from the longitudinal conveying device 3, and pushes the film-covered boards 1 out of the warehouse body 2 from the conveying interval in different directions to lay multiple film-covered boards 1. After the laying of the film-covered boards 1 is completed, the film-covered coating is injected into the guide groove of the film-covered boards 1 through the grouting channel 5, and the film-covered coating flows from the guide groove and the guide interface 17 to each film-covered board 1, thereby realizing the repair of the waterproof layer. The laying area of ​​the film-covered boards 1 is much larger than the opening area of ​​the construction groove, thereby achieving the purpose of small opening area but large repair area, thereby improving the convenience of repairing the building waterproof layer.

[0032] In order to facilitate the circulation of the coating and increase the coverage area of ​​the coating, the guide groove includes a plurality of concentric grooves 15 and a plurality of connecting grooves 16 that penetrate the plurality of concentric grooves 15. The edge of the connecting groove 16 near the coating board 1 is a guide interface 17. Figure 3When the film-covered boards 1 are laid, the edges of the adjacent film-covered boards 1 are aligned, and the flow guide grooves of different film-covered boards 1 are connected through the flow guide interface 17 .

[0033] Specifically, the film-coated boards 1 are regular polygons, which facilitate the film-coated boards 1 to be laid together. In order to connect the laid film-coated boards 1 as a whole, the film-coated boards 1 are provided with a card slot 14 or a card strip 13. Adjacent film-coated boards 1 are connected as a whole through the insertion of the card strip 13 and the card slot 14, so that the laid film-coated boards 1 form a whole and are not easy to fall apart, thereby improving the quality of the waterproof layer repair, and in combination with the repair of the film coating, the waterproof performance of the repair layer can be greatly improved.

[0034] In this embodiment, the laminated board 1 is a square board, and the laminated board 1 includes a first plate 11 and a second plate 12. The first plate 11 is provided with a clamping strip 13 on four sides, and the second plate 12 is provided with a clamping slot 14 on four sides. Figure 3 As shown in (a) and (b), the lengths of the card strip 13 and the card slot 14 are both less than the side length of the laminated board 1. The concentric slots 15 include a plurality of concentrically arranged square slots of different sizes with the same width, and there are four connecting slots 16, which are respectively located on the bisectors of the four sides of the laminated board 1, so that the flow guide interfaces 17 are all located at the midpoint of each side of the laminated board 1, thereby facilitating the precise docking of the flow guide interfaces 17 of adjacent laminated boards 1. As an alternative embodiment, the laminated board 1 can also be a regular trigon, pentagon, hexagon, etc. Since the translation angle of the square is 90° when it is laid flat, it is easy to control, so the laminated board 1 is set as a square in this embodiment.

[0035] In order to facilitate the lateral movement of the plurality of film-covered plates 1, the card strip 13 is configured as an L-shaped strip, and the corresponding card slot 14 is configured as an L-shaped slot that matches the size of the card slot 14. Figure 4 By plugging the clamping strip 13 into the clamping slot 14, when the laminated boards 1 are moved laterally, the adjacent laminated boards 1 can be dragged by each other, so as to facilitate the laying of the laminated boards 1.

[0036] In order to facilitate the horizontal conveying device 4 to push the coated board 1 to move horizontally, a linkage groove 18 is opened on the back of the first plate type and the second plate type. The center of the linkage groove 18 is consistent with the center position of the coated board 1. The horizontal conveying device 4 is connected to different positions of the linkage groove 18 to push the coated board 1 to different directions to meet the needs of laying the coated board 1.

[0037] The following is an expansion of the horizontal conveying device 4, please refer to Figure 2 and Figure 5The horizontal conveying device 4 includes a support seat 41, a support frame 42, a lifting drive 43, a turntable 44, a supporting plate 46 and a pushing assembly 45. The support seat 41 is a cylindrical shape with a closed bottom and an open top with the same diameter as the warehouse body 2. The open end of the support seat 41 is arranged toward the warehouse body 2. The support frame 42, the lifting drive 43 and the turntable 44 are all arranged inside the support seat 41. The support frame 42 is a disc-shaped support frame 42, which can be lifted and lowered along the axis direction of the support frame 41. The lifting drive 43 is a linear drive and is used to drive the support frame 42 to lift and lower. The lifting drive 43 includes but is not limited to driving methods such as a cylinder and an electric push rod. The turntable 44 is located on the side of the support frame 42 close to the warehouse body 2 and is coaxially arranged with the warehouse body 2. The turntable 44 is rotatably connected to the support frame 42 along its own axis direction. The supporting plate 46 is a circular plate with the same diameter as the turntable 44, and the supporting plate 46 is fixedly connected to the turntable 44 through four legs. The pushing assembly 45 is disposed on one side of the rotating disk 44 close to the bin body 2 and is used to cooperate with the linkage groove 18 of the film-covered board 1 to push the film-covered board 1 to move horizontally.

[0038] For details, please refer to Figure 6 and Figure 7 The pushing component 45 includes a linkage block 451 and a sliding drive 452. The linkage block 451 is an L-shaped block. The linkage block 451 is arranged on the turntable 44 along the horizontal sliding. The linkage block 451 can be embedded in any corner of the linkage groove 18. The L-shaped linkage block 451 cooperates with the square linkage groove 18, so that the linkage block 451 can be embedded in any corner of the linkage groove 18, so that the linkage block 451 can push the film-covered board 1 in four directions perpendicular to each other. The sliding drive 452 is used to drive the linkage block 451 to slide. The sliding drive 452 needs to be able to drive the linkage block 451 to move in two directions perpendicular to each other. The purpose is to facilitate the displacement of the film-covered board 1 in different ways. For details, please refer to the description of the laying process of the film-covered board 1 in the following text. In order to avoid the linkage block 451, an avoidance groove 461 is opened on the support plate 46. The avoidance groove 461 is an L-shaped groove to meet the linkage block 451. Move in two directions perpendicular to each other.

[0039] Please refer to Figure 2 and Figure 5 In order to enable the coated board 1 to translate stably and enable all the coated boards 1 to leave the conveying interval from the same plane, the thin coating system also includes a guide plate 7 and a ball 8 for guiding the coated board 1. The guide plate 7 is a circular plate, and the guide plate 7 is coaxially fixedly connected to the inner wall of the bin body 2. An avoidance hole 71 is opened in the middle of the guide plate 7. The avoidance hole 71 is a square hole. The area of ​​the avoidance hole 71 is slightly larger than the area of ​​the coated board 1 so that the coated board 1 can pass through.

[0040] In order to reduce the stability of the laminated board 1 during lateral transmission, the guide plate 7 and the supporting plate 46 are provided with a plurality of balls 8 on one side close to each other. When the laminated board 1 moves in the transmission interval, both the upper and lower sides are in contact with the balls 8, thereby facilitating the lateral movement of the laminated board 1.

[0041] Since the first molded plate 11 has a larger area of ​​the card strip 13 than the second molded plate 12, in order to enable the coated board 1 to accurately fall on the center position of the second guide plate 7, an auxiliary positioning mechanism is arranged between the second guide plate 7 and the longitudinal conveying device 3, and the auxiliary positioning system includes four movably arranged wedge blocks, not shown in the figure, the center of the connecting line of the four wedge blocks is concentric with the warehouse body 2, and the wedge surfaces are arranged toward the warehouse body 2. According to the arrangement of the coated boards 1, when the coated board 1 transmitted to the second guide plate 7 is the first molded plate 11, the four movably arranged wedge blocks adjust the distance so that the first molded plate 11 fits the edges of the four wedge blocks and falls onto the second guide plate 7; when the coated board 1 transmitted to the second guide plate 7 is the second molded plate 12, the four movably arranged wedge blocks adjust the distance so that the second molded plate 12 fits the edges of the four wedge blocks and falls onto the second guide plate 7.

[0042] Please refer to Figure 8 The longitudinal conveying assembly includes multiple groups of partition conveyor belts 31, which are arranged longitudinally and are evenly spaced on the inner wall of the warehouse body 2. In this embodiment, four groups of partition conveyor belts 31 are provided, and the partition interval size of the partition conveyor belts 31 is the same as the thickness of the film-coated board 1. The four sides of the film-coated board 1 are respectively embedded in the partition intervals of the four groups of partition conveyor belts 31, so as to achieve stable transmission of the film-coated board 1.

[0043] Since the bottom of the warehouse body 2 is suspended, in order to maintain a stable transmission interval between the warehouse body 2 and the horizontal transmission device 4, a plurality of load-bearing pins 6 are provided on the side wall of the warehouse body 2. The load-bearing pins 6 are rectangular blocks, and a wedge-shaped surface is provided at the bottom of the load-bearing pins 6, so that the load-bearing pins 6 can be abutted against the side of the building wall 9 close to the room. The plurality of load-bearing pins 6 are slidably connected with the warehouse body 2 along the radial direction of the warehouse body 2, and a synchronous driving mechanism for driving the plurality of load-bearing pins 6 to slide synchronously is provided inside the warehouse body 2. In this embodiment, four load-bearing pins 6 are provided, and the synchronous driving mechanism includes four micro cylinders, which are fixed on the inner wall of the warehouse body 2. By synchronously driving the four micro cylinders to extend and retract, the four load-bearing pins 6 can be synchronously driven to slide synchronously, so that the load-bearing pins 6 protrude or are stored in the warehouse body 2. When the load-bearing pins 6 protrude from the warehouse body 2, the warehouse body 2 can be supported on the building wall 9, reducing the possibility of deformation or tilting of the warehouse body 2 due to excessive stress.
