Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, specifically to a device for sealing and plugging leaks in the deformation joints of highway tunnels. Background Technology

[0002] Highway tunnels are underground or mountain-crossing passages for vehicles. They are classified into four categories based on length: short, medium, long, and extra-long. They consist of a portal, tunnel body, lining, ventilation, lighting, fire protection, and monitoring systems. They are constructed using drill-and-blast or shield tunneling methods. Composite lining combined with advanced grouting and deformation monitoring ensures the stability of the surrounding rock. The interior is equipped with longitudinal ventilation, LED lighting, emergency parking lanes, and fire alarms to achieve safe operation around the clock. Highway tunnels shorten mileage, avoid dangerous sections, and protect the ecology, playing a crucial role in mountain highways, urban expressways, and cross-river and cross-sea passages.

[0003] Existing sealing methods generally employ one-time grouting or adhesive rubber strips. After the grout solidifies, it forms a rigid bond with the concrete, which cannot move synchronously with the repeated expansion and contraction of the expansion joint. It often cracks and fails after several temperature cycles. Once the rubber strip ages or is torn, the original adhesive layer needs to be removed and reapplied. The work area is narrow, many tools are required, and traffic must be interrupted and the lane closed. Furthermore, traditional devices lack quick positioning and detachable structures. The specifications of the insert plate and waterstop strip are fixed. When encountering changes in joint width or local defects, the entire device must be reworked, resulting in long maintenance cycles and high labor costs. It is difficult to meet the maintenance needs of quick sealing and quick passage during the operation period. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a leak-stopping and sealing device for expansion joints in highway tunnels, including a fixing component. The surface of the fixing component has a slot, and a locking strip is engaged inside the slot. A rubber strip is fixedly connected to the front end of the locking strip. A screw is threaded to the top of the fixing component, and a rivet is inserted into the top of the fixing component. A feeding component is provided on the top of the rubber strip.

[0005] The feeding assembly has a glass base plate, with a mounting bracket fixedly connected to the top of the base plate. A threaded sleeve is fixedly connected to the top of the mounting bracket, and a threaded rod is threadedly connected inside the threaded sleeve. A hexagonal screw head is fixedly connected to the top of the threaded rod, and a pressing plate is fixedly connected to the bottom of the threaded rod. A slide rail is fixedly connected to the inner wall of the mounting bracket, and a slider is slidably connected inside the slide rail. A connecting plate is fixedly connected to the end of the slider away from the slide rail, and a locking block is locked inside the connecting plate. An insert plate is fixedly connected to the bottom of the locking block.

[0006] The above technical solution involves setting up a fastener, slot, clip, rubber strip, screw, rivet, and a feeding assembly consisting of a base plate, mounting bracket, threaded sleeve, threaded rod, hexagonal screw head, pressing plate, slide rail, slider, connecting plate, clip, and insert plate. The fastener is positioned at the edge of the expansion joint using rivets. After the clip is inserted into the slot, the rubber strip is positioned directly above the joint opening. Rotating the hexagonal screw head causes the threaded rod to move downward within the threaded sleeve, and the pressing plate simultaneously pushes the connecting plate downward along the slide rail, causing the insert plate to press the rubber strip vertically into the joint to complete the water stop.

[0007] As a further improvement to the above solution, the screw passes through the bottom of the clip and the fastener, and there are two rivets, which are symmetrically and evenly distributed inside the fastener with respect to the top center.

[0008] Through the above technical solution, the screw passes through the clip and the fastener to form an integral lock. With the symmetrical distribution of rivets, the clip remains in position under repeated pressure or temperature displacement, preventing the rubber strip from slipping off.

[0009] As a further improvement to the above solution, the threaded rod penetrates the top of the inner wall of the mounting bracket.

[0010] Through the above technical solution, the threaded rod passes through the top of the mounting bracket, so that the stroke of the pressing plate directly acts on the connecting plate, eliminating lateral load and ensuring that the rubber strip is subjected to uniform force and consistent sealing.

[0011] As a further improvement to the above solution, two slide rails are provided, and the two slide rails are evenly distributed symmetrically around the center of the front of the base plate.

[0012] Through the above technical solution, the symmetrically arranged double slide rails provide bidirectional guidance for the connecting plate, restricting torsion and offset, and ensuring that the insert plate is always pressed vertically into the expansion joint.

[0013] As a further improvement to the above solution, the pressing plate is in contact with the top of the connecting plate.

[0014] Through the above technical solution, the pressing plate and the top of the connecting plate are in direct contact, converting the rotational motion into a pure downward pressing motion, thus avoiding bending of the threaded rod.

[0015] As a further improvement to the above solution, the insert plate is located directly above the expansion joint.

[0016] With the above technical solution, the insert plate is positioned directly above the expansion joint, ensuring that the rubber strip is pushed into the joint in a straight line, eliminating the sealing blind zone caused by oblique squeezing.

[0017] As a further improvement to the above solution, the top of the connecting plate is provided with a straight slot, and the top of the insert plate is fixedly connected with bolts.

[0018] Through the above technical solution, the straight groove and bolts form a stepless adjustment interface, which allows the insert plate to be finely adjusted in the horizontal direction, adapting to local irregular deformation of the joint and enhancing the sealing adaptability.

[0019] As a further improvement to the above solution, the bolt passes through the top of the straight slot and is fixedly connected to the bottom of the connecting plate by a nut.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This utility model, by setting up a detachable clip-rubber strip combination and a threaded-slide rail linkage mechanism in the feeding assembly, uses a hexagonal screw head to drive the threaded rod to drive the pressing plate to press down the connecting plate, so that the insert plate accurately presses the rubber strip into the expansion joint, realizing a fast, single-person operation, and repeated opening and closing water-stopping operation, and can quickly stop water seepage in expansion joints.

[0022] This utility model, by setting a quick-change structure of straight groove-bolt-nut, allows the insert plate and connecting plate to be replaced instantly according to the width of the expansion joint without disassembling the fasteners, thus achieving the effect of adaptive sealing for different joint widths and maintaining long-term maintainability.

[0032] The feeding assembly 7 includes a glass base plate 71, a mounting bracket 72 fixedly connected to the top of the base plate 71, a threaded sleeve 73 fixedly connected to the top of the mounting bracket 72, a threaded rod 74 threadedly connected inside the threaded sleeve 73, a hexagonal screw head 75 fixedly connected to the top of the threaded rod 74, a pressing plate 76 fixedly connected to the bottom of the threaded rod 74, a slide rail 77 fixedly connected to the inner wall of the mounting bracket 72, a slider 78 slidably connected inside the slide rail 77, a connecting plate 79 fixedly connected to the end of the slider 78 away from the slide rail 77, a locking block 710 locking inside the connecting plate 79, and an insert plate 711 fixedly connected to the bottom of the locking block 710.

[0033] Screw 5 passes through the bottom of clip 3 and fastener 1. There are two rivets 6, which are symmetrically distributed with the longitudinal axis of fastener 1 as the center.

[0034] The threaded rod 74 penetrates the top of the inner wall of the mounting bracket 72.

[0035] There are two slide rails 77, which are evenly distributed symmetrically around the center of the front of the base plate 71.

[0036] The pressing plate 76 contacts the top of the connecting plate 79.

[0037] The insert plate 711 is located directly above the expansion joint.

[0038] The top of the connecting plate 79 is provided with a straight slot 8, and the top of the insert plate 711 is fixedly connected with a bolt 9.

[0039] Bolt 9 passes through the top of the straight slot 8 and is fixed to the bottom of the connecting plate 79 by a nut.

[0040] The implementation principle of the leakage prevention and sealing device for the expansion joint of a highway tunnel in this embodiment is as follows: when carrying out the leakage prevention and sealing work of the expansion joint of the highway tunnel, the fastener 1 is first fixed to the edge of the expansion joint by the rivet 6, and the clip 3 is inserted into the inside of the clip groove 2 so that the rubber strip 4 is located directly above the expansion joint.

Rotate the threaded rod 74 through the hexagonal screw head 75 so that the threaded rod 74 rotates inside the threaded sleeve 73. Simultaneously, the pressing plate 76 moves downward and presses the connecting plate 79. Simultaneously, the bottom of the insert plate 711 and the top of the rubber strip 4 are pressed, so that the rubber strip 4 enters the interior of the expansion joint and blocks its interior, thus stopping the water seepage.

[0042] Through the straight slot 8, the bolt 9 passes through the top of the straight slot 8, and the nut is removed from the top of the bolt 9. The appropriate insert plate 711 can be selected for installation at any time according to the size of the expansion joint.
