Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction equipment, and in particular to an in-situ profiling tunnel construction device integrating laying, fixing and spraying. Background Art

[0002] China's drainage engineering started late, and water leakage has always troubled foundation construction workers. At present, domestic waterproofing construction technology and methods are immature. They mainly use manual cooperation with trolleys to complete the laying of waterproofing membranes in multiple processes. There are deficiencies such as high labor intensity, low construction efficiency, and long construction period. The construction risk factor is high for high-altitude working scenes such as tunnels, which threatens the personal safety of construction workers. The existing drainage construction equipment has the following problems: (1) The degree of intelligence is low, and it is impossible to accurately position and lay the waterproof coating. The waterproof coating cannot fit tightly on the construction surface, which easily causes the waterproof coating to detach and the operation quality is difficult to ensure. (2) The function is single and cannot meet all the construction processes of drainage. When laying the waterproof coating, manual assistance is required for leveling and anchoring, resulting in low construction efficiency and greatly increasing construction costs. (3) The scope of application is small, and it is impossible to achieve contour laying to adapt to tunnel projects of different sizes. A single device can only be used for a single project and cannot be reused, which greatly increases the cost of tunnel construction. Summary of the invention

Among them: the power wheel 2.1 is connected to the bottom surface of the walking bracket 1.4, the drive motor 2.2 is connected to the power wheel 2.1, and the reducer 2.3 is connected to the drive motor 2.2. After the anchor-laying and spray-integrated mechanism 3 has laid the waterproof coating on the side wall of a certain part of the tunnel, the walking mechanism 2 drives the construction device of this embodiment to move forward a certain distance and then continue the construction until the reinforcement of the entire tunnel is completed.

[0036] The integrated anchoring and spraying mechanism 3 comprises: a telescopic arm group 3.1, a laying unit 3.2, an anchoring unit 3.3 and a spraying unit 3.4.

At the same time, a walking gear 3.1.6 is also rotatably connected to the side panel, and the walking gear 3.1.6 is meshed with the rack 3.1.8 on the arch track 1.1, and the walking gear 3.1.6 is connected to the driving motor fixed on the inner wall of the side panel, so that the walking gear 3.1.6 is driven to rotate, thereby driving the walking platform 3.1.1 to reciprocate along the arch track 1.1 (reference Figure 1 ), moves from one side of the arch track 1.1 to the other side, thereby completing the laying of the waterproof coating on the inner wall of the tunnel.

[0037] The upper connecting frame 3.1.2 is a horizontally arranged I-shaped structure, one end of which is connected to the upper crossbar of the walking platform 3.1.1. One end of the laying telescopic arm 3.1.3 is inserted into the upper connecting frame 3.1.2, which is provided with a hydraulic cylinder and other mechanisms, which are connected to the laying telescopic arm 3.1.3 to drive the laying telescopic arm 3.1.3 to extend and retract, so as to facilitate the laying unit 3.2 to abut against the tunnel side wall for laying the fiber reinforcement mesh 3.2.2.

[0038] refer to Figure 2 and Figure 4 , the laying unit 3.2 is rotatably connected to the other end of the laying telescopic arm 3.1.3. Specifically, the laying unit 3.2 includes: a rotating shaft 3.2.1 and an adaptive pneumatic support 3.2.3. The two ends of the rotating shaft 3.2.1 are respectively rotatably connected to the front sections of the two laying telescopic arms 3.1.3 through bearings or any other suitable components, so that the rotating shaft 3.2.1 wrapped with the fiber reinforcement net 3.2.2 is rotated to lay the fiber reinforcement net 3.2.2. At the same time, it is convenient to remove the rotating shaft 3.2.1 after the use of the fiber reinforcement net 3.2.2 and replace it with a new fiber reinforcement net 3.2.2.

[0039] Several of the adaptive pneumatic supports 3.2.3 are sequentially arranged below the rotating shaft 3.2.1, and the adaptive pneumatic supports 3.2.3 are directed toward the tunnel sidewall as a whole. The adaptive pneumatic supports 3.2.3 are mainly used to support and compress the fiber reinforcement mesh 3.2.2 during the laying process, and to adapt to the disturbance caused by the unevenness of the tunnel sidewall. Figure 4 and Figure 5, the adaptive pneumatic support 3.2.3 includes: a collar 3.2.31, a pneumatic cylinder 3.2.32, a piston rod 3.2.33, a hinge 3.2.34, a pneumatic support rod 3.2.35 and a pressure wheel 3.2.36. Among them: the collar 3.2.31 is fixed to the tail end of the pneumatic cylinder 3.2.32, the hinge 3.2.34 is tilted and fixed on the side wall of the tail end of the pneumatic support rod 3.2.35 to form a "V" shape structure, and the piston rod 3.2.33 of the pneumatic cylinder 3.2.32 is rotatably connected to the hinge 3.2.34. The pressure wheel 3.2.36 is rotatably connected to the head end of the pneumatic support rod 3.2.35, and the pressure wheel 3.2.36 is located below the rotating shaft 3.2.1 and protrudes forward to support the rib mesh 3.2.2 on the rotating shaft 3.2.1. The tail end of the pneumatic support rod 3.2.35 has a connecting hole 3.2.37, which is rotatably sleeved on the first support rod 3.2.38. The collar 3.2.31 is sleeved on the second support rod 3.2.39 and the two are fixedly connected. The first support rod 3.2.38 and the second support rod 3.2.39 are respectively fixed on two connecting rods 3.2.40 arranged obliquely downward, and the upper end of the connecting rod 3.2.40 is fixedly connected to the laying telescopic arm 3.1.3. When laying the fiber reinforcement net 3.2.2, firstly, the pneumatic cylinder 3.2.32 is used to adjust the telescopic movement of the pneumatic support rod 3.2.35 around the first support rod 3.2.38, so that the fiber reinforcement net 3.2.2 supported on the pressure wheel 3.2.36 also moves with the pneumatic support rod 3.2.35, and the fiber reinforcement net 3.2.2 is pressed against the tunnel side wall for laying, or the fiber reinforcement net 3.2.2 is separated from the tunnel side wall after laying. At the same time, when the tunnel side wall is uneven, the pneumatic support rod 3.2.35 can be used to convert the rigid contact between the pressure wheel 3.2.36 and the tunnel side wall into a flexible contact, effectively reducing the damage to the adaptive pneumatic support 3.2.3.

[0040] refer to Figure 2 One end of the spray telescopic arm 3.1.4 is inserted into the lower crossbar of the walking platform 3.1.1. The lower crossbar is provided with a hydraulic cylinder and other mechanisms, which are connected to the spray telescopic arm 3.1.4 to drive the spray telescopic arm 3.1.4 to perform telescopic movement. The spray unit 3.4 is connected to the other end of the spray telescopic arm 3.1.4 and is used to spray waterproof coating. Specifically, refer to Figure 6, the spraying unit 3.4 includes: a feed pipe 3.4.1 and a nozzle 3.4.2. Wherein: the feed pipe 3.4.1 is fixed to the other end of the spray telescopic arm 3.1.4, and the feed pipe 3.4.1 is connected to the pump body 3.4.3 so as to transport the waterproof coating to the spray pipe 3.4.1. The nozzle 3.4.2 is fixed on the feed pipe 3.4.1 and the two are connected, and the nozzle 3.4.2 is located at the lower rear of the pressure wheel 3.2.36. After the high-pressure waterproof coating is sprayed out through the nozzle 3.4.2, it adheres to the inner wall of the tunnel, and at the same time, the fiber reinforcement mesh 3.2.2 is fixed to the inner wall of the tunnel to reinforce the waterproof layer formed by the waterproof coating. The distance between the nozzle 3.4.2 and the inner wall of the tunnel can be adjusted by the telescopic movement of the spray telescopic arm 3.1.4. For this purpose, a laser distance meter 3.1.5 may be provided on the spraying telescopic arm 3.1.4. Similarly, a laser distance meter 3.1.5 may also be provided on the laying telescopic arm 3.1.3 in order to adjust the telescopic distance.

[0041] refer to Figure 2 The anchoring unit 3.3 is connected to the walking platform 3.1.1 and is located below the upper connecting frame 3.1.2 and the laying unit 3.2, and above the spraying unit 3.4. Figure 7 , Figure 8 and Fig. 9 The anchoring unit 3.3 includes: a guide rail frame 3.3.1, a rotating motor 3.3.2, a sliding support component 3.3.3, a drilling anchor pipe 3.3.4 and a propulsion component 3.3.5. Among them: The guide rail frame 3.3.1 is an angle steel structure formed by bending a plate 90°. It is tilted, and the tail end of the guide rail frame 3.3.1 is fixed to the upper connecting frame 3.1.2 by bolts and other fasteners. The guide rail frame 3.3.1 points to the inner wall of the tunnel. Several guide rail frames 3.3.1 are evenly distributed along the length direction of the upper connecting frame 3.1.2 and are arranged parallel to each other. Each guide rail frame 3.3.1 is fixed with a rotating motor 3.3.2 along its length direction, and the top surface of the rotating motor 3.3.2 is slidably connected to the lower edge of the guide rail frame 3.3.1 through a slide groove. The propulsion component 3.3.5 is fixed to the side wall of the guide rail frame 3.3.1 and is located above the rotating motor 3.3.2. The propulsion component 3.3.5 is connected to the rotary motor 3.3.2 to drive the rotary motor 3.3.2 to move along the lower edge of the guide rail frame 3.3.1, thereby making the drilling anchor pipe 3.3.4 drill forward. The propulsion component 3.3.5 can be a stepper motor or a combination of a motor and a lead screw, which can drive the rotary motor 3.3.2 to perform linear motion.

[0042] The support component 3.3.3 is fixed on the guide rail frame 3.3.1 and is located in front of the rotating motor 3.3.2. A clamp is fixed on the motor shaft of the rotating motor 3.3.2. When in use, the tail end of the drilling anchor pipe 3.3.4 is tightened in the clamp. The clamp adopts a hydraulically driven slip, which is composed of symmetrically distributed clamping blocks, and is pushed by a hydraulic cylinder to clamp / release the drilling anchor pipe 3.3.4. The head end of the drilling anchor pipe 3.3.4 has a drill bit, which slides through the through hole on the support component 3.3.3 and extends forward to the inner wall of the tunnel, so as to drill into the inner wall of the tunnel under the joint drive of the rotating motor 3.3.2 and the propulsion component 3.3.5. When the drilling anchor pipe 3.3.4 enters the inner wall of the tunnel to a set depth, the rotating motor 3.3.2 stops rotating, and the propulsion component 3.3.5 stops driving the rotating motor 3.3.2 to move. Then, after the clamp is released from the drilling anchor pipe 3.3.4, the propulsion component 3.3.5 drives the rotating motor 3.3.2 to move backward to the initial position. Then, the staff connects the grouting pipe to the grouting port 3.3.6 on the side wall of the tail end of the drilling anchor pipe 3.3.4 and performs grouting. The slurry is discharged through the slurry outlet on the side wall of the head end of the drilling anchor pipe 3.3.4 and enters the borehole until it fills the borehole. After the slurry hardens, the drilling anchor pipe 3.3.4 can be anchored into the borehole to reinforce the inner wall of the tunnel and improve the bearing capacity. When in use, the anchor-laying and spraying integrated mechanism 3 moves along the arched track 1.1 and gradually moves from one side of the tunnel to the other side, while laying the fiber reinforcement mesh 3.2.2 on the side wall of the tunnel. Then, after the anchoring unit 3.3 is used to anchor the drilling anchor pipe 3.3.4 to the inner wall of the tunnel for reinforcement, the spraying unit 3.4 is used to spray the waterproof coating on the inner wall of the tunnel. After hardening, a waterproof layer is formed. Since the fiber reinforcement mesh 3.2.2 is mixed therein, the crack resistance of the waterproof layer can be effectively prevented, and the waterproof layer can be prevented from leaking due to cracking. After the construction is completed, the staff cuts off the fiber reinforcement mesh 3.2.2 and installs a new drilling anchor pipe 3.3.4. Then, the construction device of this embodiment moves forward a certain distance under the drive of the walking mechanism 2 and continues the construction until the reinforcement of the entire tunnel is completed. The construction device of this embodiment integrates the functions of reinforcement mesh laying, anchor bolt anchoring, and waterproof coating spraying, and can realize the simultaneous operation of three processes, and realizes the precise positioning and laying of the reinforcement mesh and waterproof coating, which not only guarantees the construction quality, but also improves the construction efficiency.

[0043] In another embodiment, reference Figure 8In the above embodiment, a sealing plug 3.3.7 is fixed on the front wall of the sliding support component 3.3.3, and the drilling anchor pipe 3.3.4 moves through the sealing plug 3.3.7. When in use, the sealing plug 3.3.7 is attached to the outer wall of the surrounding rock at the drilling site to seal the drilling site. The slag generated during the drilling process passes through the gap between the sealing plug 3.3.7 and the drilling anchor pipe 3.3.4 and is discharged from the slag outlet at the bottom of the support component 3.3.3. By connecting a guide pipe to the slag outlet, the slag can also be transported to a predetermined location for collection, so as to facilitate subsequent centralized carrying to the outside of the tunnel.

[0044] In another embodiment, the outer wall of the drilling anchor pipe 3.3.4 described in the above embodiment has an external thread, which not only helps the anchoring effect between the tunnel and the drilling anchor pipe 3.3.4, but also helps to drill into the inner wall of the tunnel.

[0045] In another embodiment, the laying-fixing-spraying integrated in-situ contour-profiling tunnel construction device of the above embodiment further includes a pressure detection device, which is arranged in the grouting port 3.3.6 to monitor the grouting pressure.

[0046] In another embodiment, reference Figure 1 The laying-fixing-spraying integrated in-situ profiling tunnel construction device of the above embodiment also includes a telescopic device 1.5. The arched track 1.1 is arranged around the trolley main structure 1, and the two are connected by the telescopic device 1.5. The telescopic device 1.5 is fixed to the trolley main structure 1, and a plurality of the telescopic devices 1.5 are evenly arranged along the arched track 1.1. The arched track 1.1 adopts a structure with elastic deformation ability, so that the telescopic action of the telescopic device 1.5 such as a hydraulic cylinder can be used to appropriately change the size of the arched track 1.1 to adapt to tunnels of different sizes, so as to prevent a single device from being used only for a single project and cannot be reused, which greatly increases the cost of tunnel construction.

[0047] In another embodiment, reference Figure 1 The trolley main structure 1 in the above embodiment further includes a triangular rib plate 1.6, which is fixedly connected to the vertical beam 1.2 and the horizontal beam 1.3, so as to strengthen the bearing capacity of the trolley main structure 1.

Among them: the work platform 1.7 is horizontally fixed on the top of the vertical beam 1.2 and the horizontal beam 1.3, the ladder 1.8 is fixed on the side of the vertical beam 1.2 to facilitate the workers to climb, and the guardrail 1.9 is fixed on the edge of the work platform 1.7. In a more preferred embodiment, the horizontal beam 1.3, the work platform 1.7 and the guardrail 1.9 are all left and right parts, which are spatially staggered, so that the construction device can change its width as the size of the arched track 1.1 is adjusted, so as to adjust the size of the trolley main structure 1 in the horizontal direction to better adapt to tunnels of different sizes, so as to prevent a single device from being used only for a single project and cannot be reused, which greatly increases the cost of tunnel construction.

[0049] In another embodiment, the trolley main structure 1 of the above embodiment further includes a telescopic support leg 1.10, the upper end of which is fixed to the bottom surface of the walking bracket 1.4. The telescopic support leg 1.10 can be lifted and lowered by a hydraulic cylinder or other mechanism, so that during construction, the entire construction device is suspended in the air to prevent movement under the action of the power wheel 2.1, thereby ensuring the stability of the construction device. When the construction device needs to move, the telescopic support leg 1.10 is retracted to allow the power wheel 2.1 to be supported on the ground again.

[0050] Finally, it should be noted that any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. Although the above describes the specific implementation of the present invention in conjunction with the drawings, it is not a limitation of the protection scope of the present invention. Those skilled in the art should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
