Problems solved by technology

[0005] The anti-seepage-insulation structure of the traditional concrete dam needs to wait for the concrete dam to reach its strength before the construction of the anti-seepage layer can be carried out, which greatly prolongs the construction progress and affects the construction period. The anti-seepage-insulation-anti-icing structure of the dam is necessary

Embodiment 1

[0048] like figure 1 As shown, it is an integrated structure of anti-seepage, thermal insulation and anti-icing of an alpine dam provided by the present invention.

[0049] Embodiment 1 is suitable for alpine regions, and it includes a dam 1 with a water-facing surface 11 and a back-water surface 12. The water-facing surface 11 has a minimum water level line 13 and a maximum water level line 14, and the area between the two is a water level fluctuation zone; There is a first position 15 at or below the minimum water line 13 and a second position 16 at or above the maximum water line 14 . A first anti-seepage layer 2 is provided on the concrete surface of the upstream surface 11 of the dam 1 , and a first thermal insulation layer 3 is provided on the surface of the first anti-seepage layer 2 . A layer of second thermal insulation layer 4 is provided on the concrete surface of the back water surface 12 of the dam, and a layer of first protective layer 5 is provided on the secon...

Embodiment 2

[0052] like figure 2 , image 3 As shown, it is Embodiment 2 of the anti-seepage, thermal insulation and ice-resistant integrated structure of the alpine dam of the present invention. The difference between it and Embodiment 1 is that in the area between the first position 15 and the second position 16 of the water-facing surface 11, The first insulation layer 3 is provided with one, two or more transverse first grid grooves 31, for example, a first grid groove 31 is respectively set at the first position and the second position, or at the A greater number of first division grooves 31 are arranged in the middle area of ​​the two division grooves to separate the first insulation layer into different anti-seepage protection units A of the insulation layer; the first division grooves 31 are provided with anti-seepage and water-proof glue Bar 33 separates the first insulation layer 3 on both sides. The anti-seepage and water-proof glue strip 33 is firmly bonded to the first ant...

Embodiment 3

[0054] like figure 2 , Figure 4 , Figure 5 As shown, it is Embodiment 3 of the anti-seepage, thermal insulation and ice-resistant integrated structure of the alpine dam of the present invention. The difference between it and Embodiment 2 is that in the area between the first position 15 and the second position 16 of the water-facing surface 11, The first thermal insulation layer 3 is provided with a plurality of transverse first grid grooves 31, and several second grid grooves 32 are arranged between adjacent first grid grooves 31, and the second grid grooves 32 are connected to the first grid grooves 31. The first grid grooves 31 are connected to separate the first insulation layer into different anti-seepage protection units A of the mesh insulation layer. The shape of the anti-seepage protection unit A of the insulation layer is a triangle, a rectangle, a parallelogram or a regular hexagon or other regular geometric shapes. Adjacent anti-seepage protection units A of ...

Abstract

The invention discloses an alpine-cold dam anti-seepage and insulating and ice-resistant integrated structure and a construction method thereof. The alpine-cold dam anti-seepage and insulating and ice-resistant integrated structure comprises a dam provided with an upstream face and a downstream face; the upstream face is provided with a water level changing area, a first location and a second location; the concrete surface of the dam upstream face is provided with a layer of first anti-seepage layer, and the surface of the first anti-seepage layer is provided with a layer of first insulating layer; a concrete surface of the dam downstream face is provided with a layer of second insulating layer, and the surface of the second insulating layer is provided with a layer of first protective layer; a first insulating layer located between the first location and the second location of the upstream face is internally provided with an insulating layer anti-seepage protective unit; the first anti-seepage layer of the upstream face and the anti-seepage protective unit are provided with layers of second anti-seepage layers; and the surfaces of the second anti-seepage layers are provided with ice-resistant layers. The alpine-cold dam anti-seepage and insulating and ice-resistant integrated structure has the functions of anti-seepage, heat preservation and ice resistance, the dam concrete body cracks are prevented from generating and expanding, the damage of the insulating layers and water absorbing failure in the water level changing area of the upstream face are prevented, the erosionof the water flow erosion is prevented, and the safe operation of the dam is ensured.

Description

technical field [0001] The invention relates to an anti-seepage-insulation-anti-icing protection integrated structure suitable for concrete dams in alpine regions and its forming method, especially an anti-seepage-insulation-anti-icing protection structure suitable for the water level fluctuation area of ​​the upstream surface Permanent protection structure, and permanent thermal insulation protection structure suitable for the backwater surface, and anti-seepage and anti-freezing and thawing thermal insulation structure on the overflow surface of the dam and the flow side of the gate pier. At the same time, it is also suitable for anti-seepage-insulation-anti-icing protection of concrete dams in the weak age period more than 1 day after concrete pouring. The integrated structure can form perennial maintenance for the concrete dam. Background technique [0002] Most of the cracks in dam concrete are surface cracks, some of which will develop into deep or penetrating cracks ...
