Description

Technical Field

[0001] This invention relates to the field of water conservancy dam engineering technology, specifically to a seepage prevention and reinforcement structure for water conservancy dam engineering. Background Technology

[0002] Strengthening and preventing seepage in dikes is crucial to ensuring their safe and stable operation. If seepage problems are not addressed promptly, they can lead to major hazards such as landslides or even dike breaches.

[0003] Push-feed centrifuges, as a type of continuously operating filtration centrifuge, have a wide range of applications in the field of solid-liquid separation.

[0004] Currently, the existing push-feed centrifuges on the market adopt a one-way unloading structure. This unloading method is commonly used in centrifuge separation and discharge operations, but the discharge efficiency is low.

[0005] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a seepage prevention and reinforcement structure for water conservancy dam projects, which has the advantage of enabling bidirectional unloading of centrifuges and improving discharge efficiency.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a seepage prevention and reinforcement structure for a water conservancy dam project, including a dam body and a seepage prevention wall set on the water-facing side of the dam body. A wave wall is provided on the dam body above the seepage prevention wall. The wave wall includes a plurality of spaced bases located on the upper end face of the dam body and connected to the upper end face of the seepage prevention wall. Each base is located on the same straight line, and each base has an upwardly extending connecting seat with an upwardly facing opening at its upper end. A steel plate is inserted into the connecting seat, and the connecting seat is connected to the wall body. The upper end of the steel plate is also inserted into the wall body. The gaps between the various bases are called joints. The upper surface of the dam body is provided with a soil layer, a crushed stone cushion layer, and a cement layer. The soil layer, crushed stone cushion layer, and cement layer are all located on one side of the wall and are in contact with one side wall of the wall.

[0008] By adopting the above technical solutions, the design of the anti-seepage wall improves the anti-seepage performance of the dam body. The main purpose of setting joints between each base is to adapt to structural deformation, release stress, reduce cracking, and ensure overall stability. The base is cast first, and then the wall body is cast later. The base and the wall body are connected by steel plates to increase the connection strength and reduce the bending deformation of the wall body. The soil layer, crushed stone cushion layer, and cement layer are all located on one side of the wall body, making the upper surface of the dam body a flat road surface. Moreover, the base is designed on the upper part of the anti-seepage wall to increase the stability of the anti-seepage wall.

[0009] Preferably, the longitudinal section of the base is L-shaped, with one horizontal end of the base connected to the upper end of the seepage barrier wall and the other vertical end connected to the connecting seat. The horizontal and vertical surfaces of the base and the connecting seat are connected by an inclined surface.

Each inserting rod is hinged with a triangular plate at the end that passes through the concrete slab and is inserted into the crushed stone layer, and each inserting rod is threaded with a tensioning block on the side of the concrete slab that is away from the crushed stone layer.

[0013] Preferably, the wave-breaking wall has a water-retaining plate on one side of the water-facing side, and the water-facing side of the wall is an arc-shaped surface concave away from the water-facing side. The back side of the wall is a vertical surface. The water-retaining plate is fixed to the water-facing side of the wall by a connector, and the water-retaining plate has a hollow cavity inside. Several water-retaining strips are slidably connected to the water-facing side of the water-retaining plate. The water-retaining strips are distributed along the length of the water-retaining plate and slide inward. The cavity wall of the hollow cavity has compression springs that allow one end of the water-retaining strip to extend out of the water-facing side of the water-retaining plate. The two opposite long sides of the water-retaining strip are provided with inclined surfaces, and the two inclined surfaces make the end of the water-retaining strip extending out of the water-retaining plate T-shaped.

[0014] Preferably, the bottom of the baffle plate has a drainage hole communicating with the hollow cavity, one end of the baffle plate located inside the hollow cavity is provided with a guide rod, the inner wall of the hollow cavity is provided with a guide cylinder for the guide rod to be inserted, the bottom of the inner cylinder of the guide cylinder is provided with a pressure sensor, and the upper end of the wall is provided with a warning light. When one end of the guide rod is inserted into the bottom of the guide cylinder and abuts against the pressure sensor, the pressure sensor detects the pressure and then controls the warning light to light up.

[0015] Preferably, the upper end of the water-facing surface of the baffle plate is provided with several water inlet holes, the water inlet flow rate of the water inlet holes is greater than the water outlet flow rate of the drain holes, and a water level sensor is provided on the inner wall of the hollow cavity of the baffle plate. The water level sensor is used to detect the water level in the hollow cavity. When the water level in the hollow cavity is higher than a certain value, the water level sensor controls the warning light to light up.

[0016] Preferably, the connector includes several connecting rods pre-embedded in the wall, one end of each connecting rod is tied to the steel mesh in the wall, one end of each connecting rod extends out of the wall and passes through the baffle plate, and a locking block is threadedly connected to the end of the rod.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] A seepage prevention and reinforcement structure for hydraulic dam projects, such as Figure 1 and Figure 2 The structure includes a dam body 1 and a seepage barrier wall 11 installed on the water-facing side of the dam body 1. The seepage barrier wall 11 is a concrete wall formed using grouting technology. A wave wall is installed on the dam body 1 above the seepage barrier wall 11. The wave wall includes several spaced-apart bases 12 located on the upper surface of the dam body 1 and connected to the upper surface of the seepage barrier wall 11. All bases 12 are located on the same straight line, and the gaps between the bases 12 are joints. The length of each base 12 is 12-15 cm. The wall is 123 with a 2-centimeter joint and each base 12 has an upward-extending connecting seat 121 with an upward opening. The connecting seat 121 and the base 12 can be integrally cast. A steel plate 122 is inserted into the connecting seat 121. The connecting seat 121 is connected to the wall body 123. The upper end of the steel plate 122 is also inserted into the wall body 123, that is, the lower end face of the wall body 123 is connected to the lower end face of the connecting seat 121. The wall body 123 and the base 12 are both made using template grouting technology.

[0024] like Figure 1 and Figure 2 The upper surface of the dam body 1 is provided with a soil layer 18, a crushed stone cushion layer 181, and a cement layer 182. The soil layer 18, the crushed stone cushion layer 181, and the cement layer 182 are all located on one side of the wall body 123 and are all in contact with one side wall of the wall body 123.

[0025] like Figure 1 and Figure 2The design of the anti-seepage wall 11 improves the anti-seepage performance of the dam body 1. The main purpose of setting joints between each base 12 is to adapt to structural deformation, release stress, reduce cracking and ensure overall stability. The base 12 is cast first, and the wall body 123 is cast later. The base 12 and the wall body 123 are connected by steel plate 122 to increase the connection strength and reduce the bending deformation of the wall body 123. The soil layer 18, the crushed stone cushion layer 181 and the cement layer 182 are all located on one side of the wall body 123, making the upper surface of the dam body 1 a flat road surface. The base 12 is designed on the upper end of the anti-seepage wall 11 to increase the stability of the anti-seepage wall 11.

[0026] like Figures 1-6 The base 12 has an L-shaped longitudinal section. The horizontal end of the base 12 is connected to the upper end of the seepage barrier wall 11, and the vertical end is connected to the connecting seat 121. The horizontal and vertical surfaces of the base 12 and the connecting seat 121 are connected by an inclined surface 124. The shape of the base 12 increases its stability, which in turn improves the stability of the wall 123.

[0027] like Figures 1-6 The dam body 1 has a crushed stone layer 13 on one side of the anti-seepage wall 11 and several concrete slabs 14 arranged in contact with each other on the side of the crushed stone layer 13 away from the anti-seepage wall 11. The design of the crushed stone layer 13 increases the stability of the anti-seepage wall 11 and reduces the direct scouring of the anti-seepage wall 11 by water. The setting of the concrete slabs 14 protects the crushed stone layer 13. The horizontal end of the base 12 away from the anti-seepage wall 11 extends to one side of the upper surface of the concrete slabs 14.

[0028] Both the base 12 and the wall 123 are equipped with steel mesh (not shown in the figure) to increase the strength of the base 12 and the wall 123.

[0029] like Figures 1-6The crushed stone layer 13 is covered with a wire mesh layer, forming a protective layer for the crushed stone layer 13. Furthermore, each concrete slab 14 is fixed to the crushed stone layer 13 by inserting rods 15 into it. The lower end of the concrete slab 14 is inserted into the riverbed, and the upper end extends to the upper surface of the dam body 1. Each inserting rod 15 has a triangular plate 151 hinged at the end that passes through the concrete slab 14 and inserts into the crushed stone layer 13; that is, one end of the inserting rod 15 is hinged to a corner point of the triangular plate 151. Several arc-shaped grooves 152 are formed on both sides of the triangular plate 151 at the hinge point with the inserting rod 15. Each inserting rod 15 has a tensioning block threadedly connected to the side of the concrete slab 14 that faces away from the crushed stone layer 13. During construction, the crushed stone layer 13 and the concrete slab 14 are constructed together. First, the wire mesh layer is laid on the side of the concrete slab 14 facing the crushed stone layer 13. At this time, the wire mesh layer... The wire mesh layer is fixed in position by the various insert rods 15. Then, the concrete slab 14 is placed on one side of the crushed stone layer 13. As the crushed stone fills the space between the anti-seepage wall 11 and the concrete slab 14, the insert rods 15 are located inside the crushed stone layer 13. Since the triangular plate 151 is hinged to the insert rod 15, rotating the tensioning block causes the insert rod 15 to move a certain distance away from the crushed stone layer 13 on the side of the concrete slab 14. The triangular plate 151 then rotates around the hinge point as the insert rod 15 moves, causing the arc groove 152 on the triangular plate 151 to be locked inside the crushed stone layer 13. Alternatively, there is another situation where the crushed stone is already locked inside the arc groove 152 when filling it. In this case, the insert rod 15 will not move when the tensioning block is rotated. The design of the triangular plate 151 also makes the insert rod 15 stable inside the crushed stone layer 13, thereby stabilizing the position of the concrete slab 14.

[0030] like Figures 1-6 The wave-breaking wall 123 has a water-retaining plate 16 on one side of its water-facing side. The water-facing side of the wall 123 is an arc-shaped surface that is concave away from the water-facing side, while the back side of the wall 123 is a vertical surface. The water-retaining plate 16 is fixed to the water-facing side of the wall 123 by connectors, and the water-retaining plate 16 has a hollow cavity 161 inside. Several water-retaining strips 162 are slidably connected to the water-facing side of the water-retaining plate 16, and the water-retaining strips 162 are along the water-retaining plate 16. The baffle strip 162 is distributed along the length direction and slides towards the inside of the baffle plate 16. A compression spring 163 is provided on the cavity wall of the hollow cavity 161 so that one end of the baffle strip 162 extends out of the water-facing surface of the baffle plate 16. The two opposite long sides of the baffle strip 162 are provided with inclined surfaces. The two inclined surfaces make the end of the baffle strip 162 extending out of the baffle plate 16 T-shaped, and the short side of the T-shape is located at the end of the baffle strip 162.

[0031] like Figures 1-6The design of the water-blocking strip 162 weakens the impact of waves, and the arc-shaped surface ensures that the water-blocking strip 16 is also distributed in an arc shape. The arc-shaped distribution of the water-blocking strip 16 changes the direction of the wave force, effectively reducing the direct impact of waves on the wall 123, and causing a large amount of water to flow back into the sea when the waves roll up, reducing the amount of water crossing the top of the dike and preventing erosion of the dike top. In addition, when the waves flow along the water-blocking strip 16, they generate an impact force on the water-blocking strip 162, which facilitates the water-blocking strip 162 being pressed into the hollow cavity 161. The inclined surface 124 facilitates the force generated by the waves on the water-blocking strip 162 to move into the hollow cavity 161, playing a role in energy dissipation. After the waves separate from the water-blocking strip 16, the water-blocking strip 162 is reset again under the action of the compression spring 163.

[0032] like Figures 1-6 The bottom of the baffle plate 16 has a drainage hole 164 that communicates with the hollow cavity 161. The baffle strip 162 is provided with a guide rod 165 at one end inside the hollow cavity 161. The inner wall of the hollow cavity 161 is provided with a guide cylinder 166 for the guide rod 165 to be inserted. The guide cylinder 166 and the compression spring 163 are both located at one end of the baffle plate 162 and are spaced apart. The bottom of the inner cylinder of the guide cylinder 166 is provided with a pressure sensor. The upper end of the wall 123 is provided with a warning light. When one end of the guide rod 165 is inserted into the bottom of the guide cylinder 166 and abuts against the pressure sensor, the pressure sensor detects the pressure and then controls the warning light to light up. When the water-blocking strip 162 is partially moved into the hollow cavity 161 by the waves, the guide rod 165 moves inside the guide cylinder 166 and approaches the inner wall of the guide cylinder 166, causing the compression spring 163 to be compressed. When the waves are large, the external force applied to the water-blocking strip 162 increases, thereby increasing the length of the water-blocking strip 162 moving into the hollow cavity 161, so that the guide rod 165 contacts the inner bottom of the guide cylinder 166, thereby triggering the pressure sensor. This indicates that the waves are very large and people should be alerted. After detecting the pressure, the pressure sensor controls the warning light to light up, thus serving as a warning. Normally, a solar panel can be installed on the upper part of the wall 123 to provide power to the pressure sensor and the warning light.

[0033] like Figures 1-6 Furthermore, even after one end of the guide rod 165 comes into contact with the bottom of the guide cylinder 166, one end of the water baffle 162 remains on the outer wall of the water baffle 16, thus still weakening the impact of the waves.

[0034] like Figures 1-6The upper end of the water-facing surface of the baffle plate 16 is provided with several water inlet holes 167. The axis of the water inlet holes 167 tends to be horizontal. The water inlet flow rate of the water inlet holes 167 is greater than the water outlet flow rate of the drain holes 164. The design of the water inlet holes 167 allows the waves to enter the hollow cavity 161 when they impact the baffle plate 16, so that the hollow cavity 161 collects the water from the waves. As the waves continue to impact the baffle plate 16, the water level in the hollow cavity 161 continues to rise. A water level sensor is provided on the inner wall of the hollow cavity 161 of the baffle plate 16. The water level sensor is used to detect the water level in the hollow cavity 161. When the water level in the hollow cavity 161 is higher than a certain value, it indicates that the wave duration is long and attention should be paid. At this time, the water level sensor controls the warning light to light up.

[0035] like Figures 1-6 To facilitate the installation of the baffle plate 16 on the wall 123, the connector includes several connecting rods 17 pre-embedded in the wall 123. One end of each connecting rod 17 is tied to the steel mesh in the wall 123. One end of each connecting rod 17 extends out of the wall 123 and passes through the baffle plate 16. A locking block 171 is threadedly connected to the end of the extending rod. At this time, the connecting rods 17 and the baffle plate 162 are staggered. The locking block 171 limits the baffle plate 16 to the wall 123, making the operation simple.

[0036] like Figures 1-6 The baffle plate 16 is provided with several ribs 172 at intervals. The ribs 172 are vertically distributed and each rib 172 divides the baffle plate 162 into several segments. The connecting rod 17 extends out of the ribs 172 and the locking block 171 abuts against the side of the ribs 172 away from the baffle plate 16. At this time, the connecting rod 17 fixes the ribs 172 and the baffle plate 16 together to the wall 123. The surface of the ribs 172 that contacts the baffle plate 16 is an arc surface that fits against the surface of the baffle plate 16, which facilitates the contact between the ribs 172 and the baffle plate 16. The design of the ribs 172 can effectively improve the local stiffness and overall bending resistance of the wave wall 123 and reduce the vibration deformation caused by wave impact. The interval distribution of the ribs 172 can change the interaction between the water flow and the baffle plate 16, causing the waves to dissipate energy between the ribs 172, thereby reducing the direct impact force of the waves on the wall 123.

[0037] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
