Description

Technical Field

[0001] This utility model relates to a protective structure for material stacking construction on the top of a dam, belonging to the field of water conservancy construction technology. Background Technology

[0002] When a reservoir adopts a rockfill gravity dam structure, the quarried stones are transported to the top of the dam by trucks, dumped, and then compacted. Although there is a dry-mixed concrete extrusion retaining wall on the side of the dam top facing the panel to prevent rockfall, the dumped material will sometimes exceed the retaining wall, causing rocks to roll from the dam surface to the bottom curtain area. Therefore, protective measures need to be constructed on the sides of the dam to prevent rockfall.

[0003] Existing protection against falling rocks on the side of a dam, as described in Chinese Patent Publication No. CN216006851U, uses bamboo plywood and protective netting to block and protect against falling rocks. However, the impact or jumping of falling rocks as they roll down the dam surface can easily break through the second protective element formed by the protective netting. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a protective structure for the construction of material stockpiling on the top of a dam.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a protective structure for the construction of material stockpiling on the top of a dam, comprising:

[0007] Dam body;

[0008] A column is fixed on the overall inclined surface of the dam body. The column is rotatably hinged to a mounting plate. The bottom surface of the mounting plate contacts the dam body to generate frictional contact. A rigid mounting rod is installed with an interference fit through a hole on the top surface of the mounting plate.

[0009] A damping column is fixed on the top of the rigid mounting rod. There are multiple damping columns, which are installed on the top surface of the mounting plate through the rigid mounting rod. The damping columns have different elastic deformation amounts.

[0010] The dam body has a curtain area at the bottom of the inner side of the reservoir. The internal area of ​​the dam body is filled with rammed material, which forms a rammed layer.

[0011] The top side of the dam has a retaining wall, which is sloping towards the inside of the reservoir. After multiple retaining walls are stacked and built up, the sloping surfaces of the retaining walls form the overall sloping surface of the dam.

[0012] The columns are a plurality of linearly spaced columns; a protective net is fixedly installed on the outer side of the columns away from the dam slope.

[0013] The protective netting is a flexible netting.

[0014] The mounting plate is connected to the column by a limiting clip, which restricts the opening angle between them.

[0015] The limiting clip has through holes at both ends for connecting to the mounting plate and column.

[0016] The beneficial effects of this utility model are as follows: damping columns with different elastic deformation produce different damping to provide damping buffer or blocking for the impact or jump of falling rocks. Then, the falling rocks that lose impact or jump are blocked by the protective net, which solves the problem that falling rocks rolling down the dam surface with impact or jump can easily break through the protective net.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] like Figures 1 to 2 As shown.

[0022] This application discloses a protective structure for the construction of material stockpiling on the top of a dam, comprising:

[0023] The dam body 1 has a curtain area 11 at the bottom of the inner side of the reservoir. The internal area of ​​the dam body 1 is filled with rammed material 12. The rammed material 12 forms a rammed layer 13 that is stacked and built up.

[0024] The top side of the dam body 1 is formed by dry mixing and extrusion to form a retaining wall 2. The retaining wall is inclined towards the inner side of the reservoir. After multiple layers of retaining walls 2 are stacked and built up, the inclined surface of the retaining wall 2 forms the overall inclined surface of the dam body 1, ensuring that the overall inclined surface of the dam body 1 has a consistent slope.

[0025] The dam body 1 has columns 3 pressed into and installed on its inclined surface. The columns 3 are a plurality of linearly spaced columns. The outer side of the columns 3 away from the inclined surface of the dam body 1 is fixedly installed with a protective net 4 by binding or pressing. The protective net 4 can be a rigid net such as steel wire mesh or a flexible net such as hemp rope woven net. The technical solution of this application adopts a flexible net with lower weight.

[0026] The base of the column 3 near the dam body 1 is rotatably hinged to an installation plate 5 via hinges or other hinge components. The bottom surface of the installation plate 5 contacts the dam body 1, generating frictional contact. The top surface of the installation plate 5 has a hole for interference fit of a rigid installation rod 6. A damping column 7 made of discarded car tires is fused and fixed to the top of the rigid installation rod 6. There are multiple damping columns 7, which are installed on the top surface of the installation plate 5 via the rigid installation rod 6. The damping columns 7 have different elastic deformations. The damping columns 7 with different elastic deformations generate different damping to provide damping buffers or blocks for the impact or jump of falling rocks. After losing the impact or jump, the falling rocks are blocked by the protective net 4, which solves the problem that falling rocks rolling down the dam surface with impact or jump can easily break through the protective net.

[0027] The mounting plate 5 is connected to the column 3 by a limiting clip 51 to limit the opening angle between them; the limiting clip 51 has through holes at both ends for bolts to be connected to the mounting plate 5 and the column 3 respectively, so as to prevent the mounting plate 5 from rotating and folding towards the column 3 in use.
