Embodiment 1

[0140] Such as figure 1 , 2 7. As shown in 7, a metal mesh box slope protection structure for earth-rock dams is composed of box 1 and stone 2, and stone 2 is filled in box 1;

[0141] Such as Figure 5 , 6 As shown, the basic material of the box body 1 is a high-strength metal mesh wire 6, a supporting edge 7, and a tie wire 8, which have been treated with rust prevention. The mesh wire 6 is twisted into a knot by a single twist or a double twist or multiple twists and added with a supporting edge 7 to form a box. The bottom surface of the body 3, the side surface of the box body 4, the mesh sheet of the box body cover 5, multiple mesh sheets are assembled into a metal mesh box with anti-rust function, such as figure 1 , 2 , 3 and 4;

[0142] Such as figure 2 , 3 As shown, the structure of the box 1 can be a quadrangular structure, the height C is in the range of 10 cm to 200 cm, the length A is in the range of 10 cm to 300 cm, the width B is in the range of 10 cm to 300 cm, and t...

Embodiment 2

[0176] The construction method of the metal mesh box slope protection structure of earth-rock dam according to the present invention:

[0177] It is basically the same as Example 1, except that:

[0178] Step 1: Such as Figure 13 As shown, in accordance with the requirements of the industry standard "Design Code for Rolled Earth Dams", determine the location and area of ​​the slope protection against wave erosion in the downstream tailwater level variable amplitude zone of the core rockfill dam;

[0179] Step 8, the metal mesh box slope protection structure on both banks of the downstream face of the dam body is firmly connected to the bank slope; paved to the top elevation of the protection area, and firmly connected to other slope protection methods on the upper part;

[0180] The other steps of the downstream slope protection can be the same as in Example 1.

Embodiment 3

[0182] The construction method of the metal mesh box slope protection structure of the earth-rock dam according to the present invention: the upstream slope protection step can be the same as the first embodiment; the downstream slope protection step can be the same as the second embodiment.

Abstract

The invention relates to a metal mesh box revetment structure of an earth-rock dam and a construction method of the metal mesh box revetment structure. The metal mesh box revetment structure is formed in a way that stones are filled in a box body and the box body is knotted and fixed by mesh wires. For an area lacking of large stones, the scope of revetment is determined according to different requirements of different earth-rock dams or the requirements on washout resistance, scouring resistance or seismic resistance; a mesh, the box body and the mesh wire can be determined based on the resource of the stone of the revetment, the engineering scale and the protection requirement; the metal mesh box revetment structure is fixed to a dam body with revetment required. The metal mesh box revetment structure provided by the invention makes up the deficiency of the prior art, and meet the higher requirement of hydropower engineering, as well as having the advantages of convenience in material use, high washout resistance, scouring resistance and seismic resistance, convenience in construction, and low cost.

Description

Technical field [0001] The invention relates to a metal mesh box slope protection structure of an earth-rock dam and a construction method thereof. It relates to a core rockfill dam, a face rockfill dam and an earth dam, and is suitable for use in earth-core wall rockfill dams and asphalt concrete core wall rockfills The slope protection structure and construction methods of dams, geomembrane core rockfill dams, reinforced concrete face rockfill dams, asphalt concrete face rockfill dams, geomembrane face rockfill dams, homogeneous earth dams and zone earth dams. Background technique [0002] The existing slope protection of earth-rock dams mostly adopts piled, dry, and mortared stones, or prefabricated, cast-in-place concrete frames with stone filling, or paving prefabricated concrete blocks, or planting turf. The main problems are: high requirements on the particle size and regularity of the block stones used for slope protection, poor erosion resistance or erosion resistance or...
