Problems solved by technology
At present, the concrete slabs of the upstream dam slope of the concrete face rockfill dam are all flat slabs with equal slopes. In terms of shape, the plane form is very monotonous, lacks ups and downs, and it is difficult to integrate with the surrounding environment, and the above aesthetic requirements cannot be realized; In terms of force, affected by the uneven settlement of the rockfill dam body and the rapid change of the storage water level, it is easy to cause cracking of the face plate
Therefore, the upstream dam surface of the concrete face rockfill dam is not beautiful, and the force on the face plate is not reasonable.

Embodiment Construction
[0030] Such as figure 1 , figure 2 and image 3As shown, a curved concrete face rockfill dam in this embodiment is characterized in that: there is a curved face plate on the upstream side of the concrete face rockfill dam, and the middle part of the curved face plate 14 is convex upstream The arc surface is a row of equal-width panels 15, and the left and right parts of the curved panel 14 have straight faces parallel to the axis of the dam, and the two straight faces are a row of equal-width panels 16. There is a panel three 17 at the junction of the arc curved surface and the straight face described on the left, and there is a panel four 18 at the junction of the arc curved surface and the straight face described on the right, and these panels one 15, panel two 16, panel three 17 and panel Four 18 is the whole length from plate seat 9 to wave wall 21, and panel three and panel four both can be arc curved surface also can be straight face. There are connections between th...

The invention discloses a curved-surface-shaped concrete faced rockfill dam and a construction method thereof. According to the curved-surface-shaped concrete faced rockfill dam and the construction method thereof, a face plate in the middle of an upstream dam slope is a curved-surface-shaped protrusion, the spectacular momentum of the dam is manifested, and the appearance is attractive; a protruding face plate arranged in the face plate pressing joint areas can apply pre-pressure to the tension joint areas on the two sides, a connecting plate is arranged on the bottom surface between the slabjoints of the face plate of tension joint areas of the dam on the two sides, so that cracking of the slab joints of the tension joint areas is avoided; a semi-rigid mixture cushion layer is lined below the whole face plate, so that the stress condition of the face plate is improved; an arc hinge is arranged between the plate seat and the face plate, so that the stress of the face plate structureat the position is facilitated; and annular water stops are arranged between the face plate and the face plate and between the face plates and the plate seat, the water stop effect is improved, characteristics of safety, beauty, reasonable structure, easy construction and maintenance and the like are achieved, the curved-surface-shaped concrete faced rockfill dam is an advanced and attractive hydraulic structure, and the unification of mechanics and aesthetics is achieved.
Description
technical field [0001] The invention relates to the technical field of hydraulic structures, in particular to a curved concrete face rockfill dam and a construction method thereof. Background technique [0002] With the continuous development of the economy and society, the construction of human landscape and water conservancy projects are organically combined. While paying attention to the quality of engineering construction, architectural aesthetics and architectural modeling are emphasized, and the integration of natural landscape and human landscape is emphasized to create a beautiful environment and ecological environment. A good river landscape and waterfront environment for leisure and entertainment has become an urgent need in the field of hydraulic construction. Concrete face rockfill dam has been widely used as an important hydraulic structure. At present, the concrete slabs of the upstream dam slope of the concrete face rockfill dam are all flat slabs with equal ...
