Description

Technical Field

[0001] This invention relates to the field of water conservancy channel technology, and in particular to a seepage prevention structure and construction method for water conservancy channels based on adaptive adjustment. Background Technology

[0002] Channels typically refer to water conveyance channels such as irrigation canals and ditches. Channel seepage prevention is a key technical measure to ensure water conveyance efficiency and reduce water resource leakage during transport. In recent years, with the continuous advancement of water conservancy infrastructure construction in my country, the scale of new construction and renovation of various water conveyance, irrigation, and drainage channels has been expanding. In practical engineering applications, some water conservancy channels are constructed using on-site integral casting. However, due to limitations such as terrain conditions, construction period, and on-site working environment, more and more water conservancy channels are adopting a factory prefabrication and on-site assembly construction mode. Prefabricated channels have advantages such as fast construction speed, stable forming quality, and less susceptibility to environmental impact, and have become one of the mainstream methods for water conservancy channel construction.

[0003] Against this backdrop, the seepage prevention treatment at the joints of adjacent precast channel sections has become a core issue restricting the overall seepage prevention effect and operational stability of the channel, and is also a key focus of widespread attention in the engineering field. Currently, conventional seepage prevention methods mainly involve installing sealing strips or other sealing components between the joints of two adjacent precast channel sections. The pressure exerted during channel splicing forces the end faces of the two channel sections to tightly press against the sealing strip. The compression deformation of the sealing strip fills the joint gap, thereby preventing water from seeping outwards along the splice joint and reducing the risk of water leakage.

[0004] Existing channel splicing seepage prevention structures mostly use fixed sealing gaskets for static sealing, which lacks the ability to adaptively adjust for leakage. When the sealing gaskets age or the gaps widen, causing leakage, they cannot automatically trigger sealing reinforcement. Some active seepage prevention structures rely on external power sources such as electricity and hydraulics, which not only result in complex structures and high construction and maintenance costs, but also make them difficult to adapt to the working conditions of channels in the field without power supply. At the same time, they cannot achieve real-time leakage response and automatic pressurization and sealing, resulting in low seepage prevention reliability and failing to meet the long-term seepage prevention requirements of water conservancy channels. Therefore, this invention provides a water conservancy channel seepage prevention structure and construction method based on adaptive adjustment to solve the above problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the current seepage prevention structure and construction method of water conservancy channels based on adaptive adjustment, the present invention is proposed.

[0007] Therefore, the purpose of this invention is to provide an adaptive adjustment-based water conservancy channel seepage prevention structure and construction method, which solves the problems of existing channel splicing seepage prevention structures having no adaptive adjustment capability for static sealing, no automatic reinforcement of sealing for leakage, and some active seepage prevention structures relying on external power, high cost and difficulty in adapting to field conditions without power supply, and insufficient seepage prevention reliability.

This device includes: a water channel module and a support shell disposed on the back of the water channel module; an adaptive seepage preventer located inside the support shell for preventing seepage at the splicing parts of the water channel module. The adaptive seepage preventer includes a V-shaped elastic support and an arched elastic support disposed inside the support shell. The inner side of the support shell is filled with water-absorbing expansion balls. The expansion of the water-absorbing expansion balls compresses the V-shaped elastic support and the arched elastic support, thereby adaptively improving the sealing tightness.

[0014] As a preferred embodiment of the adaptive adjustment-based water conservancy channel seepage prevention structure of the present invention, wherein: a plurality of elastic abutment blocks are equally distributed on the inner side of the groove, and the end of the groove is configured as an arc shape that fits with the roller.

[0015] As a preferred embodiment of the adaptive adjustment-based water conservancy channel seepage prevention structure of the present invention, wherein: the two sides of the movable block are fixedly connected to limit blocks, the inner side of the groove is provided with a limit sliding groove matching the limit blocks, and the movable block is slidably connected to the groove through the limit blocks fixedly connected to the two sides.

[0016] As a preferred embodiment of the adaptive adjustment-based water conservancy channel seepage prevention structure of the present invention, wherein: a support auxiliary component is provided between the V-shaped elastic support component and the arched elastic support component for forming protective support for the V-shaped elastic support component and the arched elastic support component; The support auxiliary component includes a second auxiliary seat fixedly connected to the back of the V-shaped elastic support and a first auxiliary seat fixedly connected to the outer wall of the arched elastic support. The inner side of the second auxiliary seat is hinged with a second hinge rod, and the inner side of the first auxiliary seat is hinged with a first hinge rod. The second hinge rod and the first hinge rod are hinged to each other.

[0017] This invention also discloses a seepage prevention construction method for water conservancy channels based on adaptive adjustment, which adopts the above-mentioned seepage prevention structure for water conservancy channels based on adaptive adjustment and includes the following steps: S1. When leakage occurs at the splicing part of the water channel module, the leaked water enters the interior of the support shell and is absorbed and expanded by the water-absorbing and expanding balls filled inside the support shell. Since the interior of the support shell is filled with water-absorbing and expanding balls, the expansion of the water-absorbing and expanding balls will push the two sides of the V-shaped elastic support member to squeeze inward, so that the sealing gasket will continue to be compressed. S2. When the V-shaped elastic support is squeezed and rotated inward, it will form a traction on the second sliding seat through the third hinge rod, causing the second sliding seat to move in a straight line. During the linear movement of the second sliding seat, the roller contacts the elastic abutment block, pushing the elastic abutment block to automatically bend. The elastic abutment block itself is elastic. When the roller separates from the elastic abutment block, the elastic abutment block automatically resets under the action of its own elastic force to abut and limit the roller, so that the V-shaped elastic support is squeezed and contracted inward in a one-way direction. S3. When the splicing part of the water channel module settles, the abutment plate will squeeze the V-shaped elastic support, causing the V-shaped elastic support to move downward. This will push the second hinge rod downward, and then push the first hinge rod through the hinge part to squeeze the arched elastic support, causing the raised part of the arched elastic support to rise, thereby providing support and reinforcement.

[0018] The beneficial effects of this invention are: This invention, through the combination of components such as water-absorbing expansion balls, allows the expansion balls to push the two sides of the V-shaped elastic support to squeeze inward during expansion, thus compressing the sealing gasket. Without external power or manual intervention, the V-shaped elastic support can be automatically pushed inward to form an adaptive seal that responds to and pressurizes upon leakage, completely blocking the leakage channel and thereby improving the anti-leakage effect. This invention, through the coordination of components such as V-shaped elastic supports, allows the V-shaped elastic supports to compress and contract in one direction, forming a multi-position, progressive locking mechanism. The locking position can be automatically matched with the amount of water absorption and expansion, and the amount of settlement deformation. The sealing pressure increases continuously without impact or jumps, improving sealing stability. It can simultaneously adapt to leakage and settlement conditions, forming a permanent, stable, and irreversible sealing lock, significantly improving the reliability of seepage prevention and structural durability. This invention, through the cooperation of components such as the second sliding seat, enables the V-shaped elastic support to press inward on both sides during downward movement, increasing the clamping force of the sealing gasket. This automatically converts the vertical settlement displacement into a lateral sealing clamping force, causing the V-shaped elastic support to synchronously retract and pressurize inward without irreversible locking. This allows for adaptive closure of settlement joints and balanced eccentric load distribution, achieving passive seepage prevention without power and dual-condition superimposed protection, significantly improving sealing reliability and structural durability under settlement conditions. This invention, through the cooperation of components such as a third hinge rod, causes the V-shaped elastic support to tilt and rotate towards the higher settlement area under uneven extrusion force. This, in turn, causes the V-shaped elastic support at the lower settlement position to pull the third hinge rod, thereby pulling the second sliding seat to move linearly. The V-shaped elastic support at the higher settlement position is pressed against the sealing gasket by the abutment force of the third hinge rod. Through the adaptive tilting and fitting of the V-shaped elastic support to the wedge-shaped gap, the differential linkage of traction and locking at the lower position and pressure-increasing sealing at the higher position, combined with unidirectional locking, achieves permanent pressure maintenance, thereby improving the anti-leakage effect. This invention, through the coordination of components such as arched elastic supports, ensures that when settlement occurs at the joint of the water channel module, the abutment plate compresses the V-shaped elastic support, causing it to shift downwards. This displacement pushes the second hinge rod downwards, which in turn pushes the first hinge rod to compress the arched elastic support, raising its bulging portion and providing enhanced support. This heightened arched elastic support strengthens the structural support at the joint, while the opposing compression of the upper and lower elastic components enhances the sealing effect. It combines flexible adaptive force transmission, deformation limiting, and impact buffering, adapting to various types of settlement deformation and achieving simultaneous improvement in structural protection and seepage prevention sealing.

[0031] Reference Figures 1-7This invention provides an adaptive seepage prevention structure for water conservancy channels, comprising: a water channel module 1 and a support shell 2 disposed on the back of the water channel module 1; an adaptive seepage preventer, located inside the support shell 2, for preventing seepage at the joint of the water channel module 1, the adaptive seepage preventer including a V-shaped elastic support 5 and an arched elastic support 6 disposed inside the support shell 2, the inner side of the support shell 2 being filled with water-absorbing expansion balls, the expansion of the water-absorbing expansion balls compressing the V-shaped elastic support 5 and the arched elastic support 6, enabling them to adaptively improve the sealing tightness. The inner side of the V-shaped elastic support member 5 is provided with multiple arched abutment blocks 13, which are equally distributed on the inner side of the V-shaped elastic support member 5. Two first sliding seats 10 slide on the inner side of the support shell 2. The two first sliding seats 10 are respectively hinged to one end of the arched elastic support member 6. Two support plates 4 are fixedly connected to the inner side of the support shell 2. A set of second sliding seats 12 is slidably connected to the top of each support plate 4. A third hinge rod 9 is rotatably connected to the inner side of each set of second sliding seats 12, and the third hinge rod 9 is hinged to the V-shaped elastic support member 5. The method by which water-absorbing and expanding balls absorb water and expand is existing technology, so it is not described in detail in this solution. When leakage occurs at the splicing part of water channel module 1, the leaked water enters the interior of support shell 2 and is absorbed and expanded by the water-absorbing expansion balls filled inside support shell 2. Since the interior of support shell 2 is filled with water-absorbing expansion balls, the expansion of water-absorbing expansion balls will push the two sides of V-shaped elastic support 5 to squeeze inward, so that the sealing gasket 11 will continue to be compressed. Without external power or manual intervention, the V-shaped elastic support 5 can be automatically pushed inward to form an adaptive seal that responds to leakage and increases pressure upon leakage, completely blocking the leakage channel. With the help of the arched abutment blocks 13 arranged at equal intervals on the inner side of the V-shaped elastic support 5, the expansion thrust is converted into multi-point continuous pressing force, so that the sealing gasket 11 is uniformly compressed, without local voids, pressure blind spots, or edge lifting and detachment.

[0032] Reference Figures 3-7 The bottom of the second sliding seat 12 and the bottom of the first sliding seat 10 are both provided with one-way limiting components. The one-way limiting components include: a moving block 16 fixedly connected to the bottom of the second sliding seat 12 and the bottom of the first sliding seat 10 respectively; a plurality of rollers 17 are rotatably connected to the bottom of the moving block 16; a groove 19 is opened at the bottom of the support plate 4 and the support shell 2; a plurality of elastic abutment blocks 18 are fixedly connected to the inner side of the groove 19; the plurality of elastic abutment blocks 18 are evenly distributed on the inner side of the groove 19; the end of the groove 19 is set to be an arc shape that fits with the rollers 17; limit blocks are fixedly connected to both sides of the moving block 16; a limit sliding groove matching the limit block is opened on the inner side of the groove 19; the moving block 16 is slidably connected to the groove 19 through the limit blocks fixedly connected to both sides. When the V-shaped elastic support 5 is squeezed and rotated inward, it will pull the second sliding seat 12 through the third hinge rod 9, causing the second sliding seat 12 to move linearly. During the linear movement of the second sliding seat 12, the roller 17 contacts the elastic abutment block 18 and pushes the elastic abutment block 18 to automatically bend. The elastic abutment block 18 itself is elastic. When the roller 17 separates from the elastic abutment block 18, the elastic abutment block 18 automatically resets under its own elastic force and abuts and limits the roller 17, so that the V-shaped elastic support 5 is squeezed and contracted inward in a unidirectional manner, forming a multi-position, progressive locking. It can automatically match the locking position with the amount of water absorption expansion and settlement deformation. The sealing pressure increases continuously without impact or jump, improving the sealing stability. It can be adapted to leakage and settlement conditions simultaneously, forming a permanent and stable irreversible sealing lock, significantly improving the reliability of seepage prevention and structural durability. When the V-shaped elastic support 5 moves downward under the settlement of the water channel module 1, it will pull the third hinge rod 9. Since the second sliding seat 12 is unidirectionally limited, the two sides of the V-shaped elastic support 5 will press inward during the downward movement, increasing the pressing force of the sealing gasket 11. The vertical settlement displacement is automatically converted into the lateral sealing pressing force, so that the V-shaped elastic support 5 synchronously retracts inward and presses up irreversibly and locks itself. It can adaptively close the settlement joint, balance the load on the side, realize passive seepage prevention without power and dual-condition superimposed protection, and significantly improve the sealing reliability and structural durability under settlement conditions. When the splicing part of the water channel module 1 settles in a high-low pattern, the V-shaped elastic support 5 will be subjected to uneven extrusion force and tilt and rotate towards the higher settlement position. This will cause the V-shaped elastic support 5 at the lower settlement position to pull the third hinge rod 9, which in turn will pull the second sliding seat 12 to move linearly. The V-shaped elastic support 5 at the higher settlement position will be pressed against the sealing gasket 11 by the abutment force of the third hinge rod 9. Through the adaptive tilting and fitting of the V-shaped elastic support 5 to the wedge-shaped gap, the differentiated linkage of traction and locking at the lower position and pressure-increasing sealing at the higher position, combined with unidirectional locking, achieves permanent pressure retention, thereby improving the anti-leakage effect.

[0033] Reference Figures 4-5 A support auxiliary component is provided between the V-shaped elastic support 5 and the arched elastic support 6 to provide protective support for the V-shaped elastic support 5 and the arched elastic support 6; The support auxiliary component includes a second auxiliary seat 15 fixedly connected to the back of the V-shaped elastic support 5 and a first auxiliary seat 14 fixedly connected to the outer wall of the arched elastic support 6. The inner side of the second auxiliary seat 15 is hinged with a second hinge rod 8, and the inner side of the first auxiliary seat 14 is hinged with a first hinge rod 7, and the second hinge rod 8 and the first hinge rod 7 are hinged to each other. The water-absorbing and expanding ball is filled between the second hinge rod 8, the first hinge rod 7 and the support shell 2, and the water-absorbing and expanding ball is blocked by the second hinge rod 8 and the first hinge rod 7; When settlement occurs at the splicing part of the water channel module 1, the abutment plate 3 will compress the V-shaped elastic support 5, causing the V-shaped elastic support 5 to shift downward. This will push the second hinge rod 8 downward, and then push the first hinge rod 7 through the hinge part to compress the arched elastic support 6, causing the raised part of the arched elastic support 6 to rise, thereby providing support and strengthening the structural support at the splicing point. At the same time, the upper and lower elastic elements are compressed against each other to enhance the sealing effect. It has the functions of flexible adaptive force transmission, deformation limiting and impact buffering, and can adapt to various types of settlement deformation, so as to achieve simultaneous improvement of structural protection and seepage prevention sealing.

[0034] The following describes a construction method for seepage prevention in water conservancy channels based on adaptive adjustment, incorporating the aforementioned adaptive adjustment-based seepage prevention structure. The method includes the following steps: S1. When leakage occurs at the splicing part of the water channel module 1, the leaked water enters the interior of the support shell 2 and is absorbed and expanded by the water-absorbing expansion balls filled inside the support shell 2. Since the interior of the support shell 2 is filled with water-absorbing expansion balls, the expansion of the water-absorbing expansion balls will push the V-shaped elastic support 5 to squeeze inward on both sides, so that the sealing gasket 11 will continue to be compressed. S2. When the V-shaped elastic support 5 is squeezed and rotated inward, it will form a traction on the second sliding seat 12 through the third hinge rod 9, so that the second sliding seat 12 moves in a straight line. During the linear movement of the second sliding seat 12, the roller 17 contacts the elastic abutment block 18 and pushes the elastic abutment block 18 to automatically bend. The elastic abutment block 18 itself is elastic. When the roller 17 separates from the elastic abutment block 18, the elastic abutment block 18 automatically resets under the action of its own elastic force to abut and limit the roller 17, so that the V-shaped elastic support 5 is squeezed and contracted inward in a one-way direction. S3. When the splicing part of the water channel module 1 settles, the abutment plate 3 will squeeze the V-shaped elastic support 5, causing the V-shaped elastic support 5 to move downward. This will push the second hinge rod 8 to move downward, and then push the first hinge rod 7 through the hinge part to squeeze the arched elastic support 6, causing the raised part of the arched elastic support 6 to rise, thereby providing support and reinforcement.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
