Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a microcrystalline glass hydraulic slope protection component and a construction method thereof. Background Art

[0002] The dam is an important water conservancy project facility that blocks the tide and flood from invading the embankment, reduces the losses caused by floods and protects reservoirs. However, when the dam is attacked by strong waves, the embankment foot is easily hollowed out and collapsed. The embankment slope is eroded and thinned by the water all year round, which reduces the defense capacity and seriously threatens the safety of the dam. In order to avoid disasters, it has to be repaired repeatedly, which consumes huge manpower and material resources.

[0003] The basis for affecting the quality of dams is the materials and construction methods used in dam construction. The materials used in water conservancy project construction at home and abroad are nothing more than stone, cement, steel and geotextiles. Cement concrete is a common basic material for dam projects. Due to carbonization and strong corrosiveness of seawater, waves, ice impact and freeze-thaw, dissolution of cement hydration products, etc., its life is shortened. This is an important reason why dams, especially slope protection, need to be repaired frequently. Summary of the invention

[0004] In view of the problems existing in the above background technology introduction, the purpose of the present invention is to provide a microcrystalline glass hydraulic slope protection component and a construction method thereof that does not require cement bonding and fixation, protects the dam and reduces the maintenance cost of the dam.

[0005] The technical solution adopted by the present invention is:

[0006] A microcrystalline glass hydraulic slope protection assembly includes a plurality of microcrystalline glass slope protection boards, characterized in that: the microcrystalline glass slope protection boards are spliced ​​through the concave and convex locking structures thereon to form a slope protection layer laid on the surface of the main base soil layer of the dam, and the microcrystalline glass slope protection boards are inserted into the main base soil layer of the dam through the reserved through holes thereon by fixing columns or fixing pins and fixed on the surface of the main base soil layer of the dam. The microcrystalline glass slope protection board of the present invention protects the side of the entire dam facing the water, ensures that the dam is not corroded by water and will not deform under the scouring of water flow, prolongs the maintenance time of the dam, and reduces the cost of dam maintenance. Conventional cement slope dams need maintenance every two to three years, while dams that use microcrystalline glass boards as slope protection boards need to be maintained every eight to nine years.

[0007] Furthermore, a woven fabric soft layer for filling the gap is laid between the slope protection layer and the main body of the dam. The woven fabric soft layer of the present invention is used to fill the gap between the micro-ceramic glass slope protection board and the dam when the micro-ceramic glass is arranged, so as to reduce the interaction force between the micro-ceramic glass slope protection board and the main body of the dam under water, and protect the micro-ceramic glass slope protection board.

[0008] Furthermore, a crushed stone layer and a concrete layer are laid between the woven fabric soft row layer and the main body base soil layer of the dam. The crushed stone layer and the concrete layer of the present invention are used to reinforce the main body base soil layer of the dam, keep the base soil layer (especially the bottom base soil layer) from loosening after being soaked in water, and ensure the stability of the main body of the dam.

[0009] Furthermore, the concave-convex locking structure is circular, elliptical, dovetail groove or toothed, or a combination of these.

[0010] Furthermore, the microcrystalline glass slope protection board is a polygonal structure or a polygonal structure with a chamfered structure. When the present invention adopts a polygonal structure with a chamfered structure, the gap formed after splicing is conducive to the growth of slope protection plants and the maintenance of ecology.

[0011] Furthermore, the surface of the microcrystalline glass slope protection board is a flat structure or a structure with convex ribs and convex points. When the present invention adopts the structure of convex ribs and convex points, when the convex rib surface is used as the water-facing surface, it can play a role in wave dissipation, and when the convex rib surface contacts the dam base, it can play a role in water seepage and rapid drainage; at the same time, it can increase the friction between the dam base and the dam base.

[0012] Furthermore, the cross section of the fixing column or the fixing pin is a circular, conical or square structure, and a column cap is provided at one end of the fixing column or the fixing pin.

[0013] Furthermore, the fixing column or the fixing pin is made of one or a combination of microcrystalline glass, reinforced cement concrete, and steel.

[0014] Furthermore, the fixing column or the fixing pin is partially inserted into the main foundation soil of the dam body and partially exposed on the microcrystalline glass slope protection board. The fixing column or the fixing pin exposed on the microcrystalline glass slope protection board of the present invention has the function of eliminating waves.

[0015] The construction method of the above-mentioned microcrystalline glass hydraulic slope protection assembly has the following specific steps:

[0016] (1) The main body of the dam foundation soil is laid to form a convex platform, and the main body of the foundation soil is compacted to form the main body of the dam foundation soil layer;

[0017] (2) First lay a layer of crushed stone on the main soil layer of the dam, and then lay a layer of concrete after the crushed stone layer is embedded in the main soil layer under pressure;

[0018] (3) Laying a woven fabric soft layer on the concrete layer;

[0019] (4) interlocking and laying the glass-ceramic slope protection board on the woven fabric soft row layer;

[0020] (5) The fixing column or the fixing pin is fixed through the reserved through hole on the microcrystalline glass guard plate and inserted into the main base soil layer of the dam, and the construction is completed.

[0021] The glass-ceramic hydraulic slope protection component of the present invention can also be applied to water channels.

[0022] Compared with the prior art, the present invention has the following significant advantages: multiple microcrystalline glass guard plate assemblies with mortise and tenon structures are interlocked and arranged on the main base of the dam, without the need for adhesives such as cement, and have the functions of wave dissipation, anti-scouring, anti-erosion, and corrosion resistance, thereby protecting the embankment slope; at the same time, it has the characteristics of convenient and fast construction.

The microcrystalline glass slope protection board 1 of the present invention protects the side of the entire dam facing the water, ensures that the dam is not corroded by water and will not deform under the scouring of water flow, prolongs the maintenance time of the dam, and reduces the cost of dam maintenance. Conventional cement slope dams need maintenance every two to three years, while dams that use microcrystalline glass boards as slope protection boards need to be maintained every eight to nine years.

[0048] A woven fabric soft layer 4 for filling the gap is laid between the slope protection layer and the main base soil layer 2 of the dam in this embodiment. The woven fabric soft layer 4 of the present invention is used to fill the gap between the microcrystalline glass slope protection board 1 and the dam when the microcrystalline glass is arranged, so as to reduce the interaction force between the microcrystalline glass slope protection board 1 and the main base soil layer 2 of the dam under water flushing, and protect the microcrystalline glass slope protection board 1. A crushed stone layer and a concrete layer, that is, a concrete sand and gravel layer 5, are laid between the woven fabric soft layer 4 and the main base soil layer 2 of the dam. The crushed stone layer and the concrete layer of the present invention are used to reinforce the main base soil layer 2 of the dam, keep the base soil layer (especially the bottom base soil layer) from loosening after being soaked in water, and ensure the stability of the main body of the dam.

[0049] The concave-convex locking structure of this embodiment is one or a combination of circular, elliptical, dovetail groove or toothed shapes. Specifically, two opposite sides of the microcrystalline glass slope protection board 1 are respectively provided with a buckling convex part 13 and a buckling groove 12, and the buckling convex part 13 and the buckling groove 12 cooperate to form a concave-convex locking structure for splicing. Figure 3 , the buckling protrusion and the buckling groove are both provided with a circular structure; see Figure 4 , the buckling protrusion and the buckling groove can also be set to an elliptical structure; see Figure 5 The buckling protrusion and the buckling groove can also be arranged in a dovetail groove structure; see Figure 6 The snap-fitting protrusion and the snap-fitting groove may also be tooth-shaped structures.

When the convex rib and convex point structure is adopted in the present invention, when the convex rib surface is used as the water-facing surface, it can play a role in wave dissipation, and when the convex rib surface contacts the dam base, it can play a role in water seepage and rapid drainage; at the same time, it can increase the friction between the dam base and the dam base. For details, see Figure 8 One surface of the microcrystalline glass slope protection board 1 is uniformly distributed with strip-shaped convex ribs 14, which increase the friction between the microcrystalline glass slope protection board 1 and the woven fabric soft row layer 4, and improve the firmness of the microcrystalline glass slope protection board 1. Fig. 9 One surface of the microcrystalline glass slope protection board 1 is provided with convex points 15, and the convex points are arranged on the water-facing surface to play a role in wave dissipation.
