Description

Technical Field

[0001] The utility model relates to the technical field of concrete face rockfill dam protection, in particular to a protection structure for a concrete face rockfill dam. Background Technique

[0002] A concrete face rockfill dam is a type of rockfill dam that uses a rockfill body as a support structure and sets a concrete face on the upstream surface of the dam body as an anti-seepage structure. This type of dam combines the high strength and stability of the rockfill body with the good anti-seepage performance of the concrete face. The concrete face is located on the upstream surface of the dam body and is the key anti-seepage part of the dam. The face is usually relatively thin, generally with a thickness between 0.3 and 1.0 meters. The concrete face is connected to other parts of the dam body through structural joints such as vertical joints and peripheral joints, and is closely attached to the rockfill body, relying on the support of the rockfill body to resist water pressure.

[0003] The concrete face rockfill dam has strong adaptability to the dam foundation and can be built under various geological conditions (except for some particularly weak foundations). Compared with other types of dams, such as concrete gravity dams, most of the materials of its dam body are rockfill, and the rockfill materials can be obtained locally, reducing the transportation and procurement costs of a large amount of materials such as cement and steel.

[0004] The existing protection structures for concrete face rockfill dams have the following drawbacks: During long-term operation, the concrete face may be affected by factors such as temperature changes, freeze-thaw cycles, and water flow scouring, resulting in damage phenomena such as cracks and spalling on the face, affecting the safety and stability of the dam body. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A protection structure for a concrete face rockfill dam, including a concrete face rockfill dam body, and the concrete face rockfill dam body is successively provided with a slope, a buffer slope, and a water-facing slope from top to bottom;

[0007] A reinforcement component; the reinforcement component is arranged on the slope, and the reinforcement component is used to prevent debris on the slope from falling;

[0008] A buffer component; the buffer component is arranged on the surface of the water-facing slope, and the buffer component is used for the protection of the water-facing slope;

[0009] The reinforcement component includes a fixing plate, the fixing plates are arranged on both sides of the slope, a strengthening frame is arranged on the fixing plate, the strengthening frame is connected to the fixing plate by bolts in a threaded manner, a polystyrene foam board is bonded to the surface of the slope, four groups of drainage grooves are opened on the surface of the slope, and a drainage channel is opened on the buffer slope.

[0010] Preferably, the buffer assembly includes an outer frame, a horizontal grid is arranged on the outer frame, and mortar rubble masonry is built inside the water-facing slope.

[0015] Preferably, anti-slip grooves are arranged on the upper surface of the buffer slope.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, when the strengthening frame is fixed on the fixing plate by bolts, the compressive capacity of the slope is enhanced. The adhered polystyrene foam board has a certain compressive strength and can withstand some pressures during the construction process of the concrete slope body.

[0027] A buffer component 6; the buffer component 6 is arranged on the surface of the water-facing slope 4, and the buffer component 6 is used for the protection of the water-facing slope 4;

[0028] The reinforcement component 5 includes a fixed plate 505, the fixed plate 505 is arranged on both sides of the slope 2, a reinforcement frame 506 is arranged on the fixed plate 505, the reinforcement frame 506 is threadedly connected to the fixed plate 505 through a bolt 507, a polystyrene foam board 503 is adhered to the surface of the slope 2, four groups of drainage grooves 501 are opened on the surface of the slope 2, and a drainage canal 509 is opened on the buffer slope 3.

[0029] In this solution, during rainy and snowy weather, rainwater is drained onto the drainage channel 509 through the drainage groove 501, preventing rainwater from accumulating on the surface of the slope 2 for a long time and keeping the surface of the slope 2 wet and slippery for a long time. The adhered polystyrene foam board 503 is a common thermal insulation material, which is light in weight and has good thermal insulation performance. Its thermal conductivity is relatively low, which can effectively prevent the transfer of heat. It has a certain compressive strength and can withstand some pressures during the construction of the concrete slope body. The polystyrene foam board 503 is easy to cut and form, and can be customized according to the shape and size of the concrete slope body, which is convenient for construction and installation. By setting the polystyrene foam board 503 and the glass wool felt 504, the thermal insulation performance of the slope 2 is improved, the compressive capacity of the slope 2 is enhanced, and the noise is reduced. When the strengthening frame 506 is fixed on the fixing plate 505 through the bolts 507, the compressive capacity of the slope 2 is enhanced. Through the reinforcement assembly 5, deformation is prevented and crushed stones do not fall after the concrete cracks.

[0030] Furthermore, the buffer assembly 6 includes an outer frame 601, a cross grid 602 is arranged on the outer frame 601, and the masonry stone 603 is built inside the water-facing slope 4;

Block stones of different sizes and shapes can be selected for laying according to needs, and it has strong adaptability. The cross grid 602 on the outer frame 601 further limits the masonry stone 603. Through the buffer assembly 6, the scouring of the water-facing slope 4 by the water flow is reduced, and the water-facing slope 4 is protected.

[0032] Furthermore, four groups of shrinkage joints 502 are arranged on the surface of the slope 2.

[0033] Specifically, the set shrinkage joints 502 facilitate the release of temperature stress and adapt to deformation differences.

[0034] Furthermore, a mesh bag 508 is arranged outside the strengthening frame 506;

[0035] Specifically, the set mesh bag 508 prevents crushed stones from falling and prevents accidents from occurring.

[0036] Furthermore, a glass wool felt 504 is adhered to the surface of the slope 2, and the glass wool felt 504 is arranged on the surface of the polystyrene foam board 503.

[0037] Specifically, the adhered glass wool felt 504 has good thermal insulation performance, and at the same time has certain sound absorption performance, is corrosion-resistant and not easy to age. By setting the polystyrene foam board 503 and the glass wool felt 504, the thermal insulation performance of the slope 2 is improved, the compressive capacity of the slope 2 is enhanced, and the noise is reduced.

[0038] Furthermore, screen meshes 510 are inserted on both sides of the drainage channel 509;

[0039] Specifically, the gravel falling from the slope 2 is limited by the provided sieve 510 to prevent debris from falling when the gravel is discharged from the drainage channel 509 after being washed by rainwater.

[0040] Furthermore, anti-slip grooves 7 are formed on the upper surface of the buffer slope 3;

[0041] Specifically, the formed anti-slip grooves 7 prevent people from falling due to slipping when walking on the buffer slope 3.
