Description

Technical Field

[0001] This utility model relates to the field of reservoir spillway apron technology, specifically a reservoir spillway anti-wear, impact-resistant, and energy-dissipating apron. Background Technology

[0002] Abutments are one of the main energy dissipation and scour prevention facilities downstream of sluice gates and spillways. They are rigid structural structures used to protect the riverbed from water scouring or other erosion damage. The safety and stability of the abutment play a crucial role in the normal operation of the entire energy dissipation and scour prevention system. When the upstream water level is high, seepage along the seepage path will generate vertical uplift pressure on the abutment bottom plate, adversely affecting the abutment's anti-buoyancy stability.

[0003] Therefore, it is particularly important to design a wear-resistant, impact-resistant, and energy-dissipating apron for reservoir spillways to overcome the aforementioned technical defects and improve overall practicality. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant, impact-resistant, and energy-dissipating apron for reservoir spillways, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A type of abrasion-resistant, impact-resistant, and energy-dissipating apron for a reservoir spillway includes an apron base plate, a loose foundation, and apron bedrock. The top of the apron base plate and along its four sides are fixed with equally spaced anchor bars. Multiple sets of longitudinally and transversely distributed expansion joints are embedded within the apron base plate, and the expansion joints are filled with a filler layer. Multiple sets of evenly distributed drainage pipes are embedded within both the apron base plate and the loose foundation. A connecting flange is provided at the top of the outer side of each drainage pipe, and a permeable plate is connected to the bottom of each drainage pipe. A composite geotextile is adhered to the inner wall of each drainage pipe, and a spiral guide channel is spirally arranged on the inner wall of each drainage pipe. The interior of each drainage pipe is filled from top to bottom with layers of gravel, crushed stone, and pebbles.

[0007] As a preferred embodiment of this utility model, the bottom end of the anchor bar extends into the interior of the bedrock of the protective embankment.

[0008] As a preferred embodiment of this utility model, the filler layer is made of asphalt mortar.

[0009] As a preferred embodiment of this utility model, the drainage pipe is made of PVC material, and the connecting flange is fixed to the bottom plate of the embankment by bolts.

[0010] As a preferred embodiment of this utility model, the permeation plate has permeation holes uniformly formed inside.

[0011] As a preferred embodiment of this utility model, the spiral guide groove is designed with a spiral rib structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a reservoir spillway with an anti-wear, impact-resistant, and energy-dissipating apron. Multiple sets of anchor bars are embedded deep into the bedrock of the apron base to enhance its resistance to uplift. The apron base also includes longitudinally and laterally distributed expansion joints filled with asphalt mortar to accommodate temperature deformation and ground settlement. Drainage holes on the apron base guide seepage outflow, reducing uplift pressure and protecting the apron's safety. The multiple drainage holes enlarge the cross-sectional area and disperse water pressure, reducing uplift and preventing structural buoyancy. Spiral guide channels with spiral ribs are added inside the pipe wall to separate sediment using centrifugal force, reducing deposition. Composite geotextile wraps the inner walls of the drainage holes, enhancing anti-clogging capabilities and extending service life. Layers of gravel, crushed stone, and pebbles are filled inside the drainage holes to prevent fine particle loss while ensuring permeability. Overall, this design enhances the reservoir spillway's anti-wear, impact-resistant, and energy-dissipating capabilities. Attached Figure Description

[0023] A type of abrasion-resistant, impact-resistant, and energy-dissipating apron for a reservoir spillway includes an apron base plate 1, a loose foundation 2, and apron bedrock 3. Anchor bars 4 with equal intervals are fixed to the top of the apron base plate 1 and along its four sides. Multiple sets of longitudinally and transversely distributed expansion joints 5 are embedded inside the apron base plate 1. The expansion joints 5 are filled with a filler layer 6. Multiple sets of evenly distributed drainage pipes 7 are embedded inside the apron base plate 1 and the loose foundation 2.

[0024] The bottom end of the anchor bar 4 extends into the interior of the bedrock 3, and the filler layer 6 is made of asphalt mortar.

[0025] In this embodiment, please refer to Figure 3 A connecting flange 701 is installed at the top of the outer side of the drainage pipe 7, and a permeable plate 702 is connected to the bottom of the drainage pipe 7. The inner wall of the drainage pipe 7 is covered with a composite geotextile 703 to enhance the anti-clogging ability and extend the service life. The inner wall of the drainage pipe 7 is provided with a spiral guide channel 704 to separate silt and sand by centrifugal force and reduce sedimentation. The interior of the drainage pipe 7 is filled from top to bottom with a gravel layer 705, a crushed stone layer 706 and a pebble layer 707 to prevent fine particles from being lost while ensuring permeability, thereby improving the overall wear resistance, impact resistance and energy dissipation capacity of the reservoir spillway.

[0027] The working process of this utility model is as follows: Multiple sets of anchor bars are installed on the bottom plate 1 of the revetment, which penetrate deep into the bedrock 3 of the revetment to enhance the revetment's resistance to uplift. Expansion joints 5 are distributed longitudinally and laterally on the bottom plate 1, filled with an asphalt mortar filler layer 6 to adapt to temperature deformation and foundation settlement. Drainage holes 7 are installed on the bottom plate 1 to guide seepage out, reducing the uplift pressure generated by seepage and thus protecting the safety of the revetment. The design of multiple drainage holes 7 can expand the water passage cross-section and disperse the water flow pressure, reducing uplift pressure and preventing structural floating. A spiral guide channel 704 with spiral ribs is added inside the pipe wall to separate silt using centrifugal force, reducing sedimentation. Composite geotextile 703 is used to wrap the inner wall of the drainage holes 7, enhancing anti-clogging ability and extending service life. The drainage holes 7 are filled in layers of gravel 705, crushed stone 706, and pebble 707 to prevent fine particles from escaping while ensuring permeability, thereby comprehensively improving the reservoir spillway's wear resistance, impact resistance, and energy dissipation capabilities.
