A core-wall rockfill dam body filling structure

Abstract

This utility model discloses a core-wall rockfill dam filling structure, belonging to the technical field of water-retaining dams. It includes a dam body with a core wall zone inside. Filter layers are provided on both the front and rear sides of the core wall zone. A rectangular groove is formed at the top of the core wall zone. A disassembly assembly is installed on the inner wall of the rectangular groove. Several sets of precast piles are installed between the disassembly assembly and the rectangular groove. The precast piles are prefabricated in the factory for easy on-site installation, reducing construction time. The staggered connection of each set of precast piles not only reduces construction difficulty but also extends the connection joint distance, slowing down permeability. Loosening screws allows the limiting plate to be removed from the entry end of the limiting groove, facilitating the installation or removal of the precast piles. The reinforcing columns increase the lateral bending moment of each set of protrusions. The protruding parts of the protrusions are used to cut the incoming water flow, reducing the impact of the water flow.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7 This utility model provides a technical solution: A core-wall rockfill dam filling structure includes a dam body 1, a core wall region 2 inside the dam body 1, a filter layer 3 on both the front and rear sides of the core wall region 2, a rectangular groove 9 at the top of the core wall region 2, a dismantling component 2 7 installed on the inner wall of the rectangular groove 9, several sets of precast piles 8 installed between the dismantling component 2 7 and the inside of the rectangular groove 9, each set of precast piles 8 being staggered and overlapping, a dismantling component 1 5 installed on the side wall of the dam body 1 near the water surface, the dismantling component 1 5 being equipped with protrusions 4, and a reinforcing component 10 installed between each set of protrusions 4.

[0021] Furthermore, the precast pile 8 includes a shell 81, and several sets of shell 81 outer walls are connected to the easy-to-disassemble component 7. A rectangular cavity 82 is opened inside the shell 81. The rectangular cavity 82 is pre-filled with clay-cement modified material. The cement modified material can enhance the early strength. At the same time, the precast pile 8 is produced in the factory in advance, which is convenient for direct on-site installation and reduces the construction period.

[0022] Furthermore, the detachable component 2 7 includes a limiting groove 2 74. Several sets of limiting grooves 2 74 are evenly opened on the top of the rectangular groove 9, and each set of limiting grooves 2 74 penetrates the inner wall of the rectangular groove 9. Each set of limiting grooves 2 74 has a limiting block 2 71 inserted into its inner wall. The outer wall of each set of limiting blocks 2 71 is fixedly connected to the outer wall of the outer shell 81. Both the limiting grooves 2 74 and the limiting blocks 2 71 are T-shaped. The T-shaped design improves the interlocking between the limiting blocks 2 71 and the limiting grooves 2 74, allowing the precast pile 8 to be installed more stably inside the rectangular groove 9.

[0023] Furthermore, each set of limiting grooves 74 is in contact with limiting plates 72, and each set of limiting plates 72 is evenly fixed between the top of the dam body 1 and several sets of screws 73. Loosening the screws 73 allows the limiting plates 72 to be moved away from the entry end of the limiting grooves 74, thus facilitating the installation or removal of the precast piles 8.

[0024] Furthermore, the disassembly component 5 includes a limiting groove 53. Several sets of limiting grooves 53 are evenly opened on the top of the dam body 1. Each set of limiting grooves 53 penetrates the side of the dam body 1 near the water surface. Each set of limiting grooves 53 has a limiting block 54 inserted into its inner wall. Each set of limiting blocks 54 has a fixed connection to a protrusion 4 on its outer wall. Both the limiting block 54 and the limiting groove 53 are T-shaped.

[0025] Furthermore, the top of each set of limiting grooves 53 is in contact with a limiting plate 51. Several sets of screws 52 are evenly fixed between the limiting plate 51 and the top of the dam body 1. By loosening the screws 52, the limiting plate 51 can be removed from the entry end of the limiting groove 53, thereby facilitating the removal of the limiting block 54 with the protrusion 4 installed.

[0026] Furthermore, the reinforcement component 10 includes a groove 101. Several sets of grooves 101 are evenly opened on the side walls of several sets of protrusions 4 that are close to each other, and each set of grooves 101 penetrates the top of the protrusion 4. Reinforcing columns 103 are directly inserted into the inner walls of two sets of grooves 101 that correspond to each other. The setting of the reinforcing columns 103 increases the bending moment in the lateral direction of each set of protrusions 4.

[0027] Furthermore, each set of reinforcing columns 103 is fixedly installed on the side wall near the outer wall of the protrusion 4. Several sets of screws 104 are evenly fixed between each set of mounting plates 102 and the outer wall of the protrusion 4. The mounting plates 102 are fixed to the protrusion 4 by the screws 104, thereby restricting the movement of the reinforcing columns 103.

[0028] Furthermore, a baffle 6 is rotatably connected to the top of the dam body 1. A handle is fixedly installed on the outer wall of the baffle 6. The bottom of the baffle 6 is in contact with the top of the rectangular groove 9. The baffle 6 can be pulled by the handle to open or close the rectangular groove 9.

[0029] Furthermore, the protrusion 4 is conical in shape, with the side of the protrusion 4 closest to the water surface being a protruding part. The protruding part of the protrusion 4 is used to cut the incoming water flow and reduce the impact of the water flow.

[0030] Working principle: After connecting the precast piles 8 prefabricated in the factory with the easy-to-disassemble component 7, the precast piles 8 are installed into the rectangular groove 9 in a staggered overlapping manner. The staggered connection of each group of precast piles 8 not only reduces the construction difficulty, but also extends the distance of the connection joint and slows down the permeability. Then, the protrusions 4 are installed by the easy-to-disassemble component 5 on the side of the dam body 1 near the water surface. Then, the reinforcement component 10 is installed between each group of protrusions 4 to enhance the compressive strength of the protrusions 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
