Description

Technical Field

[0001] This utility model relates to the field of seepage prevention and water-stopping structure technology, and in particular to a modular water-stopping structure for seepage prevention of dikes and dams. Background Technology

[0002] Dikes are an important component of water conservancy projects, undertaking crucial functions such as flood control, irrigation, and water supply. Their safety and stability are directly related to the safety of people's lives and property and socio-economic development. During the operation of dikes, seepage is prone to occur due to factors such as the permeability of the dam material, differences in the geological conditions of the dam foundation, and the lack of tightness at the junction of the dam body and the bank slope. Excessive seepage can cause the phreatic line of the dam body to rise, leading to seepage damage such as piping and soil erosion, weakening the structural strength of the dam body, and even causing the dam to collapse. Therefore, seepage prevention and water sealing structures are needed. To ensure the normal operation and safety of dams, a modular anti-seepage wall joint structure is disclosed in patent application number CN202421464748.2. This structure includes trench wall reinforcement, guide wall construction, transverse short wall construction, first-stage anti-seepage wall construction, and second-stage anti-seepage wall construction. Before constructing the first and second stages of the anti-seepage wall, the transverse short wall is constructed first. During the first-stage anti-seepage wall construction, the longitudinal wall concrete is cut. During the second-stage anti-seepage wall construction, both the transverse short wall concrete and the first-stage anti-seepage wall concrete are cut, ultimately forming a C-shaped joint. This utility model, by pre-constructing the transverse short wall, significantly increases the seepage path and avoids the splitting phenomenon caused by verticality deviation in the second-stage anti-seepage wall, thereby greatly improving the waterproofing and water-stopping effect of the anti-seepage wall.

[0003] Existing waterproofing and water-stopping modules lack a locking structure when spliced ​​together, meaning they do not have the function of tightly locking adjacent modules together. This leads to gaps easily remaining between modules, reducing the effectiveness of waterproofing and water-stopping, resulting in poor stability and low practicality. Utility Model Content

[0004] This utility model relates to a modular water-stopping structure for seepage prevention in dams. It has a connecting frame and a locking screw block. Through the cooperation of the locking screw block and the connecting frame, it can achieve the function of tightly splicing adjacent seepage-stopping plates, thereby ensuring that the water-stopping sealing strip can be stably squeezed to seal the gap between adjacent seepage-stopping plates. It is stable in use and has excellent seepage prevention and water-stopping effect. At the same time, the connecting frame can stably transmit the locking force to the seepage-stopping plate during the locking process, ensuring the stability and efficiency of the connection action. It is highly flexible, stable and practical.

[0005] This utility model provides a modular water-stopping structure for seepage prevention of dikes, specifically including: a seepage prevention module, which consists of a seepage prevention plate, a connecting frame, and a locking screw block. The seepage prevention plate is fixedly installed on the side of the dike and is made of precast impermeable concrete. The connecting frame is embedded inside the seepage prevention plate, and the locking screw block is inserted into the outside of the connecting frame. Adjacent seepage prevention modules are spliced ​​together for use.

[0006] Furthermore, the seepage-proof board is provided with water-stop sealing strips on all four sides.

[0007] Furthermore, the connecting frame consists of an outer crossbar, an inner crossbar, and an action rod, with both ends of the action rod fixedly connected between the outer crossbar and the inner crossbar, respectively.

[0008] Furthermore, the actuating rod is a cross-shaped rod.

[0009] Furthermore, the outer side of the anti-seepage board is provided with an operating groove, and the outer end of the outer crossbar is exposed inside the operating groove. After the anti-seepage module is assembled, it is sealed with concrete.

[0010] Furthermore, the outer end of the outer crossbar is threaded, and the threads on the outer crossbars of adjacent seepage prevention modules have opposite directions. The outer crossbar is screwed into the inside of the locking block through the rod body thread.

[0011] This utility model provides a modular water-stopping structure for seepage prevention in dikes, which has the following beneficial effects:

[0012] 1. The combined use of the locking swivel block and the connecting frame enables the tight splicing of adjacent geomembranes, thereby ensuring that the water-stop sealing strip can be stably squeezed to seal the gaps between adjacent geomembranes. It is stable in use and has excellent seepage prevention and water-stopping effect. At the same time, the connecting frame can stably transfer the locking force to the geomembranes during the locking process, ensuring the stability and efficiency of the connection action, and improving flexibility, stability and practicality.

[0013] 2. The connecting frame is pre-embedded inside the geomembrane. Through the cross-shaped action rod, the connecting frame can stably transmit the locking and displacement force to the geomembrane during the connection and locking operation, thereby driving the geomembrane to move and achieve a tight connection. The operation is convenient and flexible. At the same time, the operating groove provides good space for the adjustment and rotation of the locking screw, which is convenient for construction and use. The operating groove will be sealed with concrete later, so that the locking screw and the connecting frame can be used as a whole, improving the integrity of the geomembrane module.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 5 Example 1:

[0029] This utility model proposes a modular water-stopping structure for seepage prevention of dikes, including: a seepage prevention module, which consists of a seepage prevention plate 2, a connecting frame 3, and a locking screw block 4. The seepage prevention plate 2 is fixedly installed on the side of the dike 1 and is made of precast impermeable concrete. The connecting frame 3 is embedded inside the seepage prevention plate 2, and the locking screw block 4 is inserted into the outside of the connecting frame 3. Adjacent seepage prevention modules are spliced ​​together for use.

[0030] The outer horizontal bar 301 has a threaded outer end, and the threads on the outer horizontal bars 301 of adjacent seepage prevention modules run in opposite directions. The outer horizontal bar 301 is screwed into the inside of the locking block 4 via the rod body thread. In use, when laying the seepage prevention modules, after fixing the first seepage prevention module at the starting position on the dam 1, the remaining seepage prevention modules can be laid out. Adjacent seepage prevention plates 2 can be connected and locked together by the locking block 4. First, the locking block 4 is screwed onto the seepage prevention plate 2 that has been fixed or laid out via the thread. After the outer crossbar 301 is inserted, the other end of the locking screw block 4 is screwed into the outer crossbar 301 of the seepage-proof plate 2 to be connected. Since the threads of the outer crossbars 301 of the adjacent seepage-proof plates 2 are opposite, the two seepage-proof plates 2 can be moved closer to each other when the locking screw block 4 is rotated, so as to lock the two seepage-proof plates 2. Water-stop sealing strips 202 are provided on all four sides of the seepage-proof plate 2. After the seepage-proof plates 2 are tightly connected, the water-stop sealing strips 202 can be stably squeezed to achieve a good water-stopping and seepage-proof effect, and the use is stable.

[0031] The connecting frame 3 consists of an outer crossbar 301, an inner crossbar 302, and an action rod 303. The two ends of the action rod 303 are fixedly connected between the outer crossbar 301 and the inner crossbar 302, respectively. The action rod 303 is a cross-shaped rod. In use, the connecting frame 3 is pre-embedded inside the impermeable plate 2. Through the cross-shaped action rod 303, the connecting frame 3 can stably transmit the locking and displacement force to the impermeable plate 2 during the connection and locking operation, thereby driving the impermeable plate 2 to move and achieve a tight connection. The operation is convenient and flexible.

[0032] The outer side of the anti-seepage plate 2 is provided with an operating groove 201, and the outer end of the outer crossbar 301 is exposed inside the operating groove 201. After the anti-seepage module is assembled, it is sealed with concrete. In use, the operating groove 201 can provide good space for the adjustment and rotation of the locking screw block 4, which is convenient for construction and use. The operating groove 201 will be sealed with concrete in the future, so that the locking screw block 4 can be used as a whole with the connecting frame 3, which improves the integrity of the anti-seepage module and further improves the stability of the device.

[0033] The working principle of this embodiment is as follows: When laying out the seepage prevention modules, after fixing the first seepage prevention module at the starting position on the dam 1, the remaining seepage prevention modules can be laid out. Adjacent seepage prevention plates 2 can be connected and locked together by locking screw blocks 4. First, the locking screw blocks 4 are screwed onto the outside of the outer crossbar 301 of the already fixed or laid seepage prevention plate 2 through the thread. Then, the other end of the locking screw blocks 4 is screwed into the outside of the outer crossbar 301 of the seepage prevention plate 2 to be connected. Since the thread direction of the outer crossbar 301 of the adjacent seepage prevention plates 2 is opposite, when the locking screw blocks 4 are rotated, the two seepage prevention plates 2 can be moved closer to each other, realizing the function of locking the two seepage prevention plates 2. The seepage prevention plates 2 are tightly locked together. After connection, the water-stop sealing strip 202 can be stably squeezed to achieve a good water-stopping and seepage prevention effect. The connecting frame 3 is pre-embedded inside the seepage prevention plate 2. Through the cross-shaped action rod 303, the connecting frame 3 can stably transmit the locking and displacement force to the seepage prevention plate 2 during the connection and locking operation, thereby driving the seepage prevention plate 2 to move and achieve a tight connection. The operation is convenient and flexible. At the same time, the operating groove 201 can provide good space for the adjustment and rotation of the locking screw block 4, which is convenient for construction and use. Moreover, the operating groove 201 will be sealed with concrete later, so that the locking screw block 4 can be used as a whole with the connecting frame 3, which improves the integrity of the seepage prevention module.
