An adaptive sealing and water-stopping structure for expansion joints in aqueducts

Abstract

This utility model relates to the field of water conservancy and hydropower engineering technology, and provides an adaptive sealing and water-stopping structure for aqueduct expansion joints. It includes a base with an extension plate slidably connected inside. Three support beams are fixedly connected to the base, and waterstops are fitted into adjacent support beams. All three support beams are equipped with a common adjustment device for easy replacement of the waterstops. The adjustment device contains a sealing device for blocking rainwater. By using the adjustment device, rotating the handle drives a threaded rod to rotate within a nut, while bearing support ensures smooth rotation. The axial movement of the threaded rod causes the nut, moving plate, and limiting plate to move synchronously, releasing the waterstop from its constraint for easy replacement. When installing a new waterstop, simply insert it into the support beam and rotate the handle in the opposite direction to reset the moving plate and limiting plate, completing the rapid fixing of the waterstop. This significantly improves replacement efficiency and reduces structural interference.

Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower engineering technology, and in particular relates to an adaptive sealing and water-stopping structure for expansion joints in aqueducts. Background Technology

[0002] In the process of transporting water, it is necessary to cross rivers, canals, roads, and gullies. At this time, aqueducts are used to ensure that the water transport is not affected. This way, the needs of agricultural irrigation, residential water use, and industrial water use can be effectively met, and the aqueduct can effectively play its role in drainage and diversion. However, with the widespread use of shell channels and thin-walled structures, leakage at component joints and seams has become more serious. Therefore, it is currently necessary to focus on the waterproofing of expansion joints in aqueducts.

[0003] In the adaptive sealing and water-stopping structure of aqueduct expansion joints, the existing waterstops are prone to sealing failure due to material aging, mechanical wear or environmental erosion after long-term service, and need to be replaced. However, the traditional replacement process has problems of complex construction and low efficiency. The main problems are: the waterstops are usually embedded in the concrete structure, and the replacement requires the partial removal of surrounding components, which not only has a long operation cycle, but may also affect the integrity of the structure, increase maintenance costs and engineering risks. Utility Model Content

[0004] This utility model provides an adaptive sealing and water-stopping structure for expansion joints in aqueducts, which aims to solve the problem that existing waterstops are prone to sealing failure due to material aging, mechanical wear, or environmental erosion after long-term service, requiring replacement. However, traditional replacement processes are complicated and inefficient.

[0005] This utility model is implemented as follows: an adaptive sealing and water-stopping structure for expansion joints in aqueducts includes: a base, an extension plate slidably connected inside the base, three support beams fixedly connected to the base, water-stopping strips being inserted into two adjacent support beams, and the three support beams being provided with the same adjustment device for easy replacement of the water-stopping strips, wherein a sealing device for blocking rainwater is installed inside the adjustment device.

[0006] Preferably, the adjusting device includes a movable plate, two limiting plates and a bearing. Two round rods are fixedly connected to both sides of the limiting plate, and the round rods are slidably connected in the corresponding limiting plates. The bearing is fixedly connected in the movable plate, and a threaded rod is fixedly connected in the bearing. A nut is sleeved on the threaded rod, and a handle is hinged in the threaded rod through a pin. The nut is connected through the movable plate.

[0007] Preferably, the movable plate has an installation groove, and a sliding rod is fixedly connected to the bottom of each of the two limiting plates. A circular plate is fixedly connected to the bottom of the sliding rod, and the sliding rod is slidably connected to the steel support beam.

[0008] Preferably, both the movable plate and the limiting plate are positioned above the supporting beam steel and are in close contact with it.

[0009] Preferably, the movable plate and the supporting beam steel are both provided with arc-shaped grooves, and the two are attached to form a semicircle for securing the waterstop.

[0010] Preferably, the sealing device includes a protective shell, a connecting rod is fixedly connected to the protective shell, a sealing ring is provided on the outer sleeve of the protective shell, and the protective shell is snapped into the mounting groove.

[0011] Preferably, the mounting groove is provided with an external thread, and the protective shell is provided with an internal thread, and the two form a threaded connection.

[0012] Preferably, the connecting rod is fitted with an anti-slip strip to prevent slippage during rotation, and the sealing ring is secured outside the mounting groove.

[0013] Compared with related technologies, the adaptive sealing and water-stopping structure for aqueduct expansion joints provided by this utility model has the following beneficial effects: 1. By setting an adjustment device, the threaded rod is driven to rotate inside the nut by rotating the handle. At the same time, the bearing support ensures smooth rotation. The axial movement of the threaded rod drives the nut, the moving plate and the limiting plate to move synchronously, so that the waterstop is released from the constraint and is easy to replace. When installing a new waterstop, simply insert it into the supporting beam steel and rotate the handle in the opposite direction to reset the moving plate and the limiting plate, thus completing the quick fixation of the waterstop. This significantly improves the replacement efficiency and reduces structural intervention.

[0014] 2. By setting a sealing device, after the waterstop is replaced, the rotating connecting rod drives the protective shell to screw in along the external thread of the mounting groove until the sealing ring is tightly fitted with the outside of the mounting groove, forming a waterproof barrier. This design effectively prevents external rainwater from seeping into the joint between the threaded rod and the nut, ensuring the long-term reliability and corrosion resistance of the adjustment device.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This utility model embodiment provides an adaptive sealing and water-stopping structure for aqueduct expansion joints, such as... Figure 1-5 As shown, it includes: a base 1, an extension plate 2 slidably connected inside the base 1, three support beams 3 fixedly connected to the base 1, waterstops 4 being installed in two adjacent support beams 3, and the three support beams 3 being provided with the same adjustment device 5 for easy replacement of the waterstops 4, and a sealing device 6 for blocking rainwater installed inside the adjustment device 5.

[0019] In a further preferred embodiment of this utility model, the adjusting device 5 includes a movable plate 51, two limiting plates 52, and a bearing 53. Two round rods are fixedly connected to both sides of the limiting plate 52, and the round rods are slidably connected within the corresponding limiting plate 52. The bearing 53 is fixedly connected within the movable plate 51, and a threaded rod 54 is fixedly connected within the bearing 53. A nut 55 is sleeved on the threaded rod 54, and a handle 56 is hinged within the threaded rod 54 via a pin. The nut 55 is connected through the movable plate 51, and an installation groove 57 is provided within the movable plate 51. A sliding rod 58 is fixedly connected below each of the two limiting plates 52, and a round plate 59 is fixedly connected below the sliding rod 58. The sliding rod 58 is slidably connected within the supporting beam steel 3. The movable plate 51 and the limiting plates 52 are both clamped above the supporting beam steel 3 and form a tight fit with the supporting beam steel 3. An arc-shaped groove is provided on the contact surface of the movable plate 51 and the supporting beam steel 3, and the two are in contact to form a semicircle for clamping the waterstop 4.

[0020] In this embodiment, the round rods on both sides of the limiting plate 52 form a sliding connection with the corresponding limiting plate 52. This design ensures that the limiting plate 52 moves smoothly when the adjusting device 5 is activated, avoiding skewing or jamming. The guiding effect of the round rods improves the accuracy of the displacement of the limiting plate 52 and reduces frictional loss, making the replacement process of the waterstop 4 smoother and more reliable. The sliding rod 58 passes through the supporting beam steel 3 and is slidably connected to it. The lower end is limited by the round plate 59, which not only ensures the vertical movement stability of the limiting plate 52, but also prevents the sliding rod 58 from coming off. This cooperation method ensures that the limiting plate 52 always keeps in close contact with the supporting beam steel 3 during the adjustment process, ensuring the centering of the waterstop 4 when it is installed, and simplifying the assembly process.

[0021] In a further preferred embodiment of this utility model, the sealing device 6 includes a protective shell 61, a connecting rod 62 fixedly connected to the protective shell 61, a sealing ring 64 covering the protective shell 61, the protective shell 61 being engaged in the mounting groove 57, the mounting groove 57 having an external thread, the protective shell 61 having an internal thread, and the two forming a threaded connection; the connecting rod 62 being covered with an anti-slip strip 63 to prevent slippage during rotation; and the sealing ring 64 being engaged in the mounting groove 57.

[0022] In this embodiment, the sealing ring 64 is engaged on the outside of the mounting groove 57 and forms a tight contact with the groove wall through elastic deformation. This interference fit effectively blocks the rainwater penetration path, while allowing the protective shell 61 to move axially under the drive of the thread, taking into account both dynamic sealing and ease of operation, and significantly improving the corrosion resistance of the threaded connection. The anti-slip strip 63 provided on the outside of the connecting rod 62 increases the frictional resistance during operation and avoids slippage when manually rotating the connecting rod 62. This detailed design improves the operability of the sealing device 6 adjustment, especially in humid environments, ensuring the force application efficiency and reliability of the tightening process of the protective shell 61.

[0023] In summary, rotating the handle 56 drives the threaded rod 54 to rotate within the nut 55, while the bearing 53 ensures smooth rotation. The axial movement of the threaded rod 54 causes the nut 55, the moving plate 51, and the limiting plate 52 to move synchronously, releasing the waterstop 4 from its constraint for easy replacement. When installing a new waterstop 4, simply insert it into the supporting beam steel 3, and rotate the handle 56 in the opposite direction to reset the moving plate 51 and the limiting plate 52, thus quickly fixing the waterstop 4. After the waterstop 4 is replaced, rotating the connecting rod 62 drives the protective shell 61 to screw into the external thread of the mounting groove 57 until the sealing ring 64 is tightly fitted with the outside of the mounting groove 57, forming a waterproof barrier. This design effectively prevents external rainwater from seeping into the joint between the threaded rod 54 and the nut 55, ensuring the long-term reliability and corrosion resistance of the adjusting device 5.
