Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy engineering, and in particular relates to a closed anti-seepage reinforcement structure of a mortar-laid stone dam or a concrete dam. Background Art

[0002] Both rubble-stone dam and concrete dam are a type of dam. The main difference between the two is that the main material of rubble-stone dam is stone mortar, while the main material of concrete dam is reinforced concrete. As the main classification of dam bodies, the two are used in large quantities. The main way to test the performance of the dam body is to evaluate the strength and impermeability of the dam body. Therefore, it is necessary to propose a closed anti-seepage reinforcement structure for rubble-stone dam or concrete dam.

[0003] According to the search, the patent document with publication number CN205314056U discloses a closed anti-seepage reinforcement structure of a mortar-made stone dam or concrete dam, including a new concrete anti-seepage panel arranged on the upstream dam surface of the dam body and a main grouting curtain obtained by re-grouting and reinforcement of the original grouting curtain; a concrete cover plate is arranged at the bottom of the new concrete anti-seepage panel, an auxiliary grouting curtain is arranged between the main grouting curtain and the concrete cover plate, the auxiliary grouting curtain and the main grouting curtain are in a cross-arrangement state, the angle between the auxiliary grouting curtain and the horizontal plane is 60°, and the length of the auxiliary grouting curtain is 10m.

[0004] The existing mortar-made stone dams or concrete dams have the following main deficiencies when in use: the existing mortar-made stone dams or concrete dams have insufficient overall displacement resistance when in use, and the dam body strength cannot be fully guaranteed. During the flood season, long-term water pressure will cause the internal stress of the dam body to be unable to be released, and cracks will inevitably appear in the internal structure of the dam body over time. At the same time, the impermeability of the soil at the bottom of the dam body cannot be fully guaranteed. Utility Model Content

[0007] Two concrete anti-seepage plates are arranged at the bottom of the dam body, and embedded steel plates are arranged on the sides of the two concrete anti-seepage plates close to each other, and a plurality of X-shaped anti-tilt frames are welded between the two embedded steel plates.

[0008] Preferably, a pre-embedded hinged plate is provided on one side of the dam body, and three rotating seats are provided on the pre-embedded hinged plate.

[0009] Preferably, a supporting steel member is rotatably connected to the rotating seat, and three supporting steel members are fixedly connected to a mortar floor slab at one end away from the rotating seat.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Reference Figure 1-Figure 4, a mortar-stone dam or concrete dam closed anti-seepage reinforcement structure, including.

[0022] A dam body 1, a corridor 2 is arranged inside the dam body 1, two grouting waterproof layers 3 are arranged at the bottom of the dam body 1, and the grouting waterproof layers 3 are arranged obliquely. The oblique arrangement of the grouting waterproof layers 3 can make the waterproof layers more fully contact with water, so that the protective performance of the grouting waterproof layers 3 can be fully exerted;

[0023] Two concrete anti-seepage plates 4 are arranged at the bottom of the dam body 1, and a pre-buried steel plate 5 is arranged on one side of the two concrete anti-seepage plates 4 close to each other. A plurality of X-shaped anti-tilt frames 6 are welded between the two pre-buried steel plates 5. The concrete anti-seepage plates 4 can further improve the anti-seepage performance of the device, and the pre-buried steel plates 5 can provide an installation fulcrum for the X-shaped anti-tilt frame 6. The X-shaped anti-tilt frame 6 can form a stable triangular structure to ensure the strength of the concrete anti-seepage plates 4;

[0024] A pre-embedded hinged plate 7 is provided on one side of the dam body 1, and three rotating seats 8 are provided on the pre-embedded hinged plate 7. A supporting steel member 9 is rotatably connected to the rotating seat 8. A mortar floor plate 10 is fixedly connected to one end of the three supporting steel members 9 away from the rotating seat 8. Four tensile plates 11 are fixedly connected to the bottom of the mortar floor plate 10. A vertical steel cage is provided in the tensile plate 11. Eight tensile bars 12 are fixedly connected to the tensile plate 11 away from one end of the dam body 1 among the four tensile plates 11. The ribs 12 penetrate the other three tensile plates 11 and are connected to the vertical steel cage inside them. One end of the eight tensile bars 12 is fixedly connected to the concrete anti-seepage plate 4 on the corresponding side. The tensile plate 11 at the bottom of the mortar floor slab 10 can ensure the tensile performance of the mortar floor slab 10. At the same time, the supporting steel member 9 can ensure the supporting force on one side of the dam body 1 and the overall strength of the dam body 1. The concrete anti-seepage plate 4 can be further stabilized by the connection of the tensile bars 12.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] The inclined setting of the grouting waterproof layer 3 can make the waterproof layer more fully contact with water, so that the protective performance of the grouting waterproof layer 3 can be fully exerted, the concrete anti-seepage plate 4 can further improve the anti-seepage performance of the device, and the embedded steel plate 5 can provide an installation fulcrum for the X-shaped anti-tilt frame 6. The X-shaped anti-tilt frame 6 can form a stable triangular structure to ensure the strength of the concrete anti-seepage plate 4;

[0027] The tensile plate 11 at the bottom of the mortar floor slab 10 can ensure the tensile performance of the mortar floor slab 10, while the supporting steel member 9 can ensure the supporting force on one side of the dam body 1 and the overall strength of the dam body 1. The concrete anti-seepage plate 4 can be further stabilized by the connection of the tensile reinforcement 12;

[0028] By setting two concrete anti-seepage plates 4 and a grouting waterproof layer 3 to form multiple anti-seepage layers, the problem of poor anti-seepage performance of the existing dam body can be avoided. At the same time, by setting 9 supporting steel structures and tensile reinforcement 12, while ensuring the stability and compression resistance of the dam body, the stability of the anti-seepage layer is also guaranteed, further ensuring the long-term anti-seepage performance of the dam body.
