Problems solved by technology
The surface of the composite geomembrane is exposed without covering, and the construction position of the anti-wave wall is relatively close to the laying range of the composite geomembrane. During the construction process, complex measures must be taken to protect the composite geomembrane, and avoid the establishment of the anti-wave wall, steel bar binding, pouring, etc. The damage caused by construction measures, therefore, inevitably leads to difficult construction, slow progress of the project, and difficult to meet the protection effect

Embodiment 1
[0023] Embodiment 1: A wave wall structure of a hydropower station dam, including a cast-in-place base 1, a prefabricated wall 2, and a post-cast connecting support block 3, wherein:
[0024] The cast-in-place base 1 is cast in-situ with reinforced concrete, 12m long, and in the shape of a cuboid, on which there is a square groove 4 with a width of 50 cm. The square groove 4 is set in the same direction as the cast-in-place base 1 and is located at the front of the cast-in-place base 1 The rear part of the cast-in-place base 1 is pre-embedded with inclined fixed steel bars 5;
[0025] The prefabricated wall 2 is prefabricated with reinforced concrete in the shape of a cuboid, with a length of 3m. The connecting steel bars 6 are reserved on the back and the steel connecting plates 7 are reserved on both sides. The wall is in the shape of a cuboid. The bottom of the prefabricated wall 2 is placed on the cast-in-place In the square groove 4 of the base 1; after being hoisted and ...

The invention discloses an anti-wave wall structure of the hydropower station dam, and applied to the composite geomembrane panel rockfill dam. The construction difficulty is effectively lowered, andthe construction period is shortened. The anti-wave wall structure of the hydropower station dam comprises a cast-in-place base, a prefabricated wall body and a post-cast connecting support block, wherein the cast-in-place base adopts reinforced concrete cast-in-place and is in a cuboid shape, a square groove is formed in the cast-in-place base, the square groove is formed in the front portion ofthe cast-in-place base, and an inclined fixed reinforcing steel bar is pre-buried at the rear part of the cast-in-place base; the prefabricated wall body is prefabricated in a cuboid shape by adoptingreinforced concrete, a connecting steel bar is reserved at the back of the steel plate, steel connecting plates are reserved on the two sides of the steel plate, and the bottom of the prefabricated wall body is placed in the square groove of the cast-in-place base through lifting; the back surface of the wall body, the bottom plate and the welded steel bar form a triangular area, concrete is poured, so that a post-cast connection supporting block is formed. According to the anti-wave wall structure of the hydropower station dam, damage to the composite geomembrane in the construction processis effectively avoided, the integrity of the composite geomembrane is guaranteed, the construction difficulty is reduced, and the construction efficiency is improved.
Description
[0001] Technical field [0002] The invention relates to a hydropower station earth-rockfill dam project, in particular to a hydropower station dam wave-proof wall structure suitable for composite geomembrane face rockfill dams, effectively reducing construction difficulty, saving construction period, and obtaining power generation benefits in advance. Background technique [0003] Composite geomembrane face rockfill dam is a kind of rockfill dam, which is widely used in water conservancy, hydropower and environmental protection engineering fields. This type of dam retains the characteristics of strong adaptability to geological conditions of the face rockfill dam, simple construction and good seismic performance, and has the characteristics of fast construction of the anti-seepage system, strong ability to adapt to the deformation of the dam body, and low overall investment. [0004] At present, the most commonly used is to use composite geomembrane to cover the surface of th...
