Description

Technical Field

[0001] This utility model relates to the field of revetment structure technology, specifically a stepped energy dissipation revetment structure. Background Technology

[0002] Stepped energy dissipation revetments, common protective and energy dissipation facilities in water conservancy projects, disperse water flow energy and reduce flow velocity through a stepped structure, effectively reducing erosion of riverbanks. They also possess ecological and landscape functions and are widely used in river regulation, reservoir bank protection, and urban waterfront projects. Existing stepped revetment structures are mainly divided into two forms: cast-in-place and prefabricated assembly. In cast-in-place construction, formwork must be erected on-site according to design dimensions, steel reinforcement tied, concrete poured, and cured. This method is greatly affected by weather and terrain, resulting in a long construction period. While prefabricated stepped revetments can shorten on-site construction time, splicing requires aligning adjacent components and then screwing in bolts one by one through pre-drilled bolt holes on the side or bottom of the components. Aligning these bolt holes on-site requires repeated adjustments using cranes, pry bars, and other equipment, making each splicing time-consuming and inefficient. Utility Model Content

[0003] This utility model proposes a stepped energy dissipation revetment structure, which allows for simple and quick connection and installation of individual revetment units through a fastening mechanism, shortening the construction cycle while ensuring a more stable connection.

[0004] Therefore, the technical solution adopted is as follows: A stepped energy dissipation revetment structure includes several revetment units connected by a fastening mechanism. Each revetment unit is a stepped prefabricated component. One side of each revetment unit has a horizontally inserted positioning groove, and the other side has a horizontally positioned positioning pin fixed at the position corresponding to the positioning groove. Both sides of each revetment unit have vertically positioned dovetail grooves. When two adjacent revetment units are connected, the positioning pins are inserted into the positioning grooves. The fastening mechanism includes a vertically positioned fastening seat. Both sides of the fastening seat have horizontally positioned sliding grooves. Dovetail blocks are slidably connected inside each sliding groove. Two dovetail blocks are vertically inserted into the corresponding dovetail grooves between two adjacent revetment units.

[0005] A further technical solution is that sealed bearings are embedded at both the upper and lower ends of the fastening seat, and a bidirectional screw is connected between the two sealed bearings. A slider matching its thread is sleeved at both ends of the bidirectional screw. Two first movable seats are fixed on each slider, and two second movable seats are fixed on each dovetail block. A connecting rod is hinged between the first movable seat and the adjacent second movable seat through a pin. One end of the fastening seat is rotatably connected to an internal hexagon adjustment head that is sleeved on the bidirectional screw and matches its thread.

[0006] A further technical solution is that a sealing ring is provided between the slide and the dovetail block.

[0007] A further technical solution is that the upper surface of each revetment unit is fixed with wave-shaped energy dissipation teeth, and the sides are provided with honeycomb-shaped energy dissipation holes.

[0008] A further technical solution is that the top of the revetment unit is provided with a horizontally arranged arc-shaped docking groove, and the bottom is fixed with an arc-shaped docking block that matches the arc-shaped docking groove.

[0009] The beneficial effects of this utility model are: 1. The revetment units are connected by positioning pins and positioning slots to achieve rapid horizontal alignment and splicing, ensuring precise connection between adjacent prefabricated components. The dovetail blocks of the fastening mechanism slide along the grooves of the fastening seats and insert into the dovetail slots of adjacent stepped prefabricated components, forming a double fixation in both the longitudinal and transverse directions, which enhances the overall stability of the revetment structure. At the same time, the stepped design can gradually weaken the impact of water flow, adapting to different water level energy dissipation requirements. The overall structure is easy to install, has strong scour resistance, and is suitable for riverbank protection scenarios.

[0010] 2. When the bidirectional screw rotates, it can drive the sliders at both ends to move synchronously towards or away from each other, providing synchronous driving force for the extension and retraction of the dovetail blocks, ensuring that the dovetail blocks on both sides move synchronously, eliminating errors, and making the connection between the two revetment units more tight and stable.

Detailed Implementation

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0015] like Figure 1 - Figure 6 As shown, a stepped energy dissipation revetment structure includes several revetment units 101 connected by a fastening mechanism 2. Each revetment unit 101 is a stepped prefabricated component. One side of each revetment unit 101 has a horizontally inserted positioning groove 105, and the other side has a horizontally fixed positioning pin 108 corresponding to the positioning groove 105. The two sides of each revetment unit 101 have vertically arranged dovetail grooves 106. When two adjacent revetment units 101 are connected, the positioning pin 108 is inserted into the positioning groove 105. The fastening mechanism 2 includes a vertically arranged fastening seat 201. Both sides of the fastening seat 201 have horizontally arranged sliding grooves 204. Dovetail blocks 202 are slidably connected inside the sliding grooves 204. Two dovetail blocks 202 are vertically inserted into the two corresponding dovetail grooves 106 between two adjacent revetment units 101.

[0016] In this embodiment, the adjacent revetment units 101 are first aligned laterally by inserting the positioning pins 108 into the positioning grooves 105 to form a preliminary stepped revetment frame; then the fastening seat 201 of the fastening mechanism 2 is placed in the middle of the two dovetail grooves 106 of the adjacent revetment units 101 and inserted accordingly to form a stable connection structure.

[0017] The fastening seat 201 has sealed bearings embedded at both its upper and lower ends, and a double-acting screw 206 is connected between the two sealed bearings. Both ends of the double-acting screw 206 are fitted with sliders 207 that are threadedly matched with them. Each slider 207 has two first movable seats 208 fixed on it, and each dovetail block 202 has two second movable seats 210 fixed on it. The first movable seats 208 and their adjacent second movable seats 210 are hinged to a connecting rod 209 by a pin. One end of the fastening seat 201 is rotatably connected to an internal hexagonal head 203 that is threadedly matched on the double-acting screw 206.

[0018] The sealed bearing inside the fastening seat 201 provides stable rotation support for the bidirectional screw 206, reducing frictional loss while ensuring the sealing performance of the bidirectional screw 206. The threads at both ends of the bidirectional screw 206 are opposite in direction, and when rotated, they can drive the sliders 207 at both ends to move synchronously towards or away from each other, providing synchronous driving force for the extension and retraction of the dovetail block 202, ensuring that the dovetail blocks 202 on both sides move synchronously and improving the fastening effect.

[0019] The first movable seat 208 of the slider 207 and the second movable seat 210 of the dovetail block 202 are hinged by a connecting rod 209. When the slider 207 moves, it can push or pull the dovetail block 202 along the slide groove 204 through the connecting rod 209, converting the rotational motion of the bidirectional screw 206 into the linear motion of the dovetail block 202, realizing the clamping or separation of the dovetail block 202 and the dovetail groove 106. The operation is flexible and the transmission is stable. The operator can easily turn the adjusting head with an Allen wrench to drive the bidirectional screw 206 to rotate, thereby controlling the extension and retraction of the dovetail block 202. The Allen wrench structure is not easy to strip the threads, and the torque transmission is stable during adjustment, making it easy to control the tightening force of the dovetail block 202 and improving the reliability of the fastening operation.

[0020] like Figure 6 As shown, a sealing ring 205 is provided between the slide groove 204 and the dovetail block 202. The inner side of the sealing ring 205 abuts against the outer side of the dovetail block 202. The sealing ring 205 on the inner side of the slide groove 204 abuts tightly against the outer side of the dovetail block 202, which can effectively prevent mud and water from entering the interior of the slide groove 204 and extend the service life of the fastening mechanism 2.

[0021] like Figure 2As shown, each revetment unit 101 has a wave-shaped energy-dissipating tooth 103 fixed to its upper surface, and honeycomb-shaped energy-dissipating holes 102 opened on its sides. The wave-shaped energy-dissipating teeth 103 at the upper end of the revetment unit 101 can break the surface layer of the water flow, disperse the water flow energy, and weaken the impact of the water flow on the top of the revetment; the honeycomb-shaped energy-dissipating holes 102 on the sides can form vortices when the water flows through, further consuming the kinetic energy of the water flow. The dual energy-dissipating structure greatly reduces the scouring force of the water flow, improves the erosion resistance of the revetment, and protects the stability of the riverbank soil. The top of the revetment unit 101 is provided with a horizontally set arc-shaped docking groove 104, and the bottom is fixed with an arc-shaped docking block 107 that matches the arc-shaped docking groove 104. The arc-shaped docking groove 104 at the top of the revetment unit 101 and the arc-shaped docking block 107 at the bottom are adapted to each other. When the upper and lower revetment units 101 are spliced, the arc-shaped docking block 107 is embedded in the arc-shaped docking groove 104 to enhance the sealing and stability of the connection between the upper and lower layers. The arc-shaped structure can disperse the impact force of water flow on the splicing joint, prevent water flow from seeping into the interior of the revetment through the gap, prevent soil loss, and improve the overall seepage prevention performance of the revetment.

[0022] Specifically, in use, this stepped energy dissipation revetment structure first aligns adjacent revetment units 101 laterally by inserting them into positioning slots 105 using positioning pins 108. The upper and lower prefabricated components are then longitudinally spliced ​​by embedding arc-shaped connecting blocks 107 into arc-shaped connecting slots 104, forming a preliminary stepped revetment frame. Subsequently, the fastening seat 201 of the fastening mechanism 2 is placed at the connection point of adjacent prefabricated components. Using an Allen wrench, the Allen head 203 is rotated, driving the bidirectional screw 206 to rotate under the support of a sealed bearing. This causes the sliders 207 at both ends to move synchronously towards each other. The sliders 207 are connected via the first movable seat 208 and the connecting rod 20... The hinged engagement of 9 with the second movable seat 210 pushes the dovetail block 202 to slide along the slide groove 204, so that when they move towards each other, they abut against the inner side of the dovetail groove 106, increasing the firmness between two adjacent revetment units 101. The sealing ring 205 in the slide groove 204 prevents the entry of mud and sand. When in use, when the water flow impacts the revetment unit 101, the upper wave-shaped energy dissipation teeth 103 break the surface of the water flow and disperse the energy, and the honeycomb-shaped energy dissipation holes 102 on the side make the water flow form a vortex to further dissipate the kinetic energy. The stepped structure combined with the double energy dissipation design weakens the impact force of the water flow layer by layer, realizing the dual functions of riverbank protection and energy dissipation.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
