Description
Technical Field
[0001] The invention relates to the field of dam reinforcement, in particular to a dam water seepage and reinforcement structure and a construction method. Background Art
[0002] The dam, a key component of this water conservancy project, refers to the dike that blocks rivers and retains water. It is mainly used for water-retaining embankments in reservoirs, rivers, etc. It is an important flood control measure and also plays a key role in power generation, irrigation, and shipping.
[0003] The sudden rise of river water will increase the water pressure downstream, which may pose a threat to the stability of the dam, causing the dam to deform and then cause leakage. The dam needs to be reinforced before the sudden rise, but some reinforcement equipment can only simply block the waves when in use. The waves directly hit the reinforcement equipment, which will accelerate the damage of the reinforcement device. At the same time, when the reinforcement device is damaged and needs to be replaced, some of the reinforcement devices need to be disassembled and replaced as a whole, which reduces the replacement efficiency. Therefore, it is necessary to propose dam seepage and reinforcement structure and construction methods. Summary of the invention

[0007] Specifically, an outer wall on one side of the fixed block is fixedly connected to a water tank, an inner wall of the water tank is slidably connected to a floating plate, both ends of the floating plate are penetrated with a storage cavity, the inner wall of the storage cavity is slidably connected to a limiting block, and the inner walls on both sides of the water tank relative to the position of the limiting block are penetrated with a first limiting hole and a second limiting hole, one end of the limiting block extends into the first limiting hole, and a pull rope is fixedly connected to the lower surface of the floating plate.
[0008] Specifically, the upper end of the water tank is provided with an opening and is fixedly connected to a water inlet pipe, the lower surface of the water tank is provided with an opening and is fixedly connected to a drain pipe, one end of the pull rope extends outside the drain pipe and is fixedly connected to a sealing plug, and the sealing plug matches the drain pipe.
[0009] Specifically, a third spring is fixedly connected to the lower surface of the floating plate, the other end of the third spring is fixedly connected to the water tank, a fourth spring is fixedly connected to the inner wall of one side of the storage cavity, and the other end of the fourth spring is fixedly connected to the limit block.
[0010] Specifically, positioning nails are fixedly connected to the four corners of the fixing block, a water leakage hole is penetrated through the concave part of the wave plate, and drainage holes are penetrated through the inner bottom wall of the cavity and the slide groove.
[0011] Specifically, a threaded hole is formed through the inner wall of one side of the slide groove, a fixing bolt is threadedly connected to the threaded hole, one end of the fixing bolt is abutted against the top block, a conical push block is slidably connected to the inner wall of the rectangular groove, one end of the fixing bolt extends into the groove and abuts against the conical push block, and the conical push block abuts against the conical block.
[0012] The construction method of dam seepage and reinforcement structure includes the following steps:
[0013] The first step is to fill the water seepage of the dam with epoxy resin glue, and abut the water tank against the outer wall of the dam. Multiple fixing blocks can be stacked, and the rectangular block is inserted into the hole opened in the fixing block. The rectangular block moves into the rectangular groove opened in the buffer block and abuts against the second spring, and the fixing block and the water tank are fixed to the outer wall of the dam by positioning nails;
[0014] The second step is that when the water level rises, river water enters the water tank through the drainage pipe, and the water in the water tank gradually rises until it pushes the floating plate to move upward. When the buoyancy of the floating plate is greater than the elastic force of the fourth spring, the floating plate pushes the limit block to move out of the first limit hole, and the third spring pushes the floating plate to move upward. The floating plate drives the pull rope and the sealing plug to move upward until the sealing plug blocks the drainage pipe. The fourth spring pushes the limit block to move into the second limit hole to limit and fix the floating plate. By increasing the weight of the water tank, the deadweight of the dam is increased, thereby improving its anti-slip and anti-overturning capabilities. When the water level drops, the sealing plug blocks the drainage pipe and the water in the water tank cannot be discharged. The increased deadweight of the dam will not decrease. When the river water is stable, the sealing plug can be pulled outward to expose the drainage pipe, and the water is discharged through the drainage pipe. The sealing plug drives the floating plate downward through the pull rope to move the floating plate to one side of the first limit hole. The fourth spring pushes the limit block to move into the first limit hole to limit and fix the floating plate.
[0015] The third step is that when the river water hits waves, the waves hit the wave plate, the wave plate drives the slider to move upward, the slider drives the connected buffer block and the rectangular block to move upward, the second spring buffers the rectangular block, the buffer block and the wave plate, reduces the force of the waves hitting the fixed block, and the water leakage hole can discharge the accumulated water on the surface of the wave plate. When the wave plate is damaged, the fixing bolt can be turned out to drive the L-shaped connecting block to move toward the top block and compress the first spring. The L-shaped connecting block is moved out of the T-slot, and the L-shaped connecting block and the wave plate can be moved out of the slider, and the L-shaped connecting block and the wave plate are replaced. The new L-shaped connecting block and the wave plate are inserted into the slider, and the first spring pushes the L-shaped connecting block to move into the T-slot. When the fixing bolt is turned into the screw hole, the top block is limited and fixed. When the elasticity of the second spring needs to be adjusted, the fixing bolt is turned inward, and the fixing bolt pushes the conical push block downward, and the conical push block pushes the conical block to move toward the rectangular block. The rectangular block and the conical push block squeeze the second spring, and the resistance of the wave plate can be adjusted by adjusting the elastic force of the second spring.
[0016] Beneficial effects of the present invention:
[0017] (1) The dam seepage and reinforcement structure and construction method described in the present invention, when the river surface is covered with waves, the waves push the wave plate to move upward, and the wave plate drives the slider and the buffer block to move upward. The second spring buffers the buffer block to reduce the impact of the waves on the dam. The fixing bolt can be rotated inward, and the fixing bolt pushes the conical push block to squeeze the conical block. The conical block compresses the length of the second spring to increase the resistance of the wave plate. When the wave plate is damaged and needs to be replaced, the fixing bolt can be turned out, and the wave plate and the L-shaped connecting block can be moved outward. The L-shaped connecting block is removed from the slider, and a new L-shaped connecting block can be inserted into the slider for splicing. The buffering force of the wave plate can be adjusted according to the size of the waves, thereby increasing the flexibility of use. When replacing the wave plate, there is no need to disassemble the entire reinforcement equipment, thereby speeding up the replacement efficiency.
[0018] (2) The dam seepage and reinforcement structure and construction method described in the present invention, when the water level rises, water enters the water tank through the water inlet pipe. When the water in the water tank gradually increases, the water pushes the float plate to move upward, and the third spring pushes the float plate and the sealing plug to move upward. The sealing plug blocks the water inlet pipe, increasing the deadweight of the water tank. When the river water recedes, the water in the water tank cannot flow out, which still increases the deadweight of the dam. The weight of the reinforcement equipment can be gradually increased according to the degree of river level rise, and the deadweight of the dam can be increased by increasing the weight of the water tank, thereby increasing the stability of the dam. At the same time, the weight of the reinforcement equipment will not decrease as the river water drops, thereby ensuring the stability of the dam. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The construction method of dam seepage and reinforcement structure includes the following steps:
