Description

Technical Field

[0001] The present application relates to the field of tunnel construction, and in particular to a micro-leakage plugging construction equipment for an operating shield tunnel. Background Art

[0002] Grouting refers to the process of hydraulically delivering slurry into the fissures, fault fracture zones of subway tunnels or the joints and cracks of the building itself. Grouting can improve the impermeability and integrity of the grouted strata or buildings, improve the overall stability, and ensure the safe operation of subway tunnels.

[0003] The existing grouting rotary jet pile-forming equipment used for subway tunnel reinforcement and plugging has the following disadvantages during use. During use, the existing grouting rotary jet pile-forming equipment used for subway tunnel reinforcement and plugging has the following disadvantages. Since the grouting rotary jet pile-forming equipment for tunnel reinforcement and plugging in the prior art is too large, for some tunnels with smaller cracks and fault fracture zones, it takes a long time to transfer large equipment, resulting in extended construction period. Moreover, large equipment usually requires 3-4 people to work together, but it is easy to cause safety accidents in a limited space. Therefore, a miniaturized equipment is needed.

Several clamping plates are connected to form a circular profile that is consistent with the outer wall profile of the pulp barrel or waste barrel, thereby ensuring that the pulp barrel or waste barrel can be firmly fixed to the base plate.

Landing gear 5a is evenly distributed at the four corners of the baseplate 1. This conventional landing gear 5a, similar in structure to aircraft landing gear, comprises wheels, a supporting lifting system, and a support system. The wheels of the landing gear 5a are larger than those of the tunnel wheels 5. When the device is not traveling along the tunnel's tracks, it can be moved by lowering the landing gear 5a. Because the tunnel has both track and ground surfaces, the device can be moved within the tunnel by switching between the tunnel wheels 5 and the landing gear 5a. When in the tunnel, the landing gear 5a is retracted within the baseplate 1, allowing the device to travel along the tunnel's tracks. When not traveling along the tracks, the landing gear 5a can be used to move the device. Alternatively, in other embodiments, the landing gear 5a can be raised and lowered by a hydraulic cylinder to achieve switching between the landing gear 5a and the tunnel wheels 5.

When the first support rod 14 is flipped to the side of the second support rod 15, the first cover plate 16 on the second support rod 15 is removed and screwed to the first support rod 14 to prevent the slider 10 from escaping from the chute 9. When the grouting area is lower or higher, the second support rod 15 can be rotated at the connection point between the first support rod 14 and the second support rod 15 to rotate and flip the second support rod 15 relative to the first support rod 14, thereby changing the height of the bracket 6 and thus changing the height of the drill rod. At the same time, through the cooperation of the slider 10 and the chute 9, the height of the drill rod can be fine-tuned to ensure that the height of the drill rod can be accurately aligned with the grouting area, thereby ensuring precise grouting and eliminating the need for auxiliary tools for grouting, thereby reducing the difficulty of grouting for workers and improving work efficiency.

[0068] Working process: Using the existing lifting holes in the tunnel segments, the drill rod is passed through the lifting holes of the tunnel segments. After grouting, a sealing layer of sufficient thickness is formed at the cracks on the outer side of the tunnel segments, thereby repairing the leaks. Specifically, the equipment is moved to the construction area near the tunnel leakage point using the tunnel wheels 5. The push-pull handle 4 is used to adjust the equipment position to ensure that the drill rod is facing the lifting holes of the tunnel segments. According to the height of the lifting holes, the height of the bracket 6 is adjusted. The fasteners 22 between the first support rod 14 and the second support rod 15 are loosened. The second support rod 15 is rotated via the hinge seat 17 so that it is folded relative to the first support rod 14 until the initial height of the drill rod approaches the target position. Through the cooperation of the slide 9 and the slider 10, the vertical position of the fixing plate 11 is fine-tuned so that the tip of the drill rod is precisely aligned with the lifting hole. After the adjustment is completed, the fasteners 22 and the block 29 are locked to ensure the stability of the bracket 6 and the slider 10. The feed mechanism and power head are then tilted by rotating the drive element 7 to align them with the lifting hole. The power head 8 then rotates the drill pipe 360° to spray grout. This fully automated process, from positioning and grouting to waste recovery, significantly reduces manual labor and improves the accuracy and efficiency of leak plugging. It is particularly suitable for rapid repair work in operating shield tunnels.
