Embodiment
[0040] Such as figure 1 As shown, the retaining wall structure of a dump site in a plateau alpine region according to the present invention includes a core-clad structure 1 and an anchor structure 4, one end of the anchor structure 4 is fixedly connected to the core-clad structure 1, and the other end of the anchor structure 4 is connected to the foundation 9. Anchored and fixed, the core-wrapped structure 1 includes block stones 2 and cement blanket 3, the cement blanket 3 is used as the shell of the core-wrapped structure 1, and the block stones 2 are filled in the shell.
[0041]In this embodiment, the core-wrapped structure 1 is provided with five layers in the vertical direction, the bottom is the first layer, the top is the fifth layer, and the height of each layer is 1m, and the five layers overlap to form a trapezoid, including Each layer of the core structure 1 is separated horizontally by the cement blanket 3 into multiple sash grids with a width of 4m and a length o...

The invention relates to the technical field of geotechnical engineering, and discloses a retaining wall structure and a construction method for a dreg site in a plateau alpine region. The retaining wall structure of the dreg site includes a core structure and an anchor structure, and one end of the anchor structure is fixed to the core structure The other end of the anchor structure is anchored and fixed to the foundation. The core structure includes block stones and cement blankets. The cement blanket is used as the shell of the core structure, and the block stones are filled in the shell. The present invention replaces the retaining wall structure formed by masonry rubble or concrete with a cored structure, which not only avoids the influence of freezing and thawing, but also ensures the durability of the retaining wall structure. The stability of overturning does not require concrete maintenance, and the construction cost is low. This construction method uses less machinery, is fast in forming, and has high construction efficiency. It is especially suitable for popularization and application in waste dumps in plateau alpine regions.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a retaining wall structure and a construction method for an abandoned muck field in a plateau alpine region. Background technique [0002] A large amount of dregs will be generated during the construction of the project. In order to meet the requirements of environmental protection, it is necessary to reinforce and protect the dregs field. The commonly used reinforcement and protection measures for the dregs dump are structures built with mortared stone or concrete retaining walls. things. [0003] The oxygen content in the air in the plateau area is low, the labor efficiency of personnel is low, and the construction safety risk is high. The construction and maintenance of concrete structures in the alpine area are very difficult. Ordinary masonry rubble mortar or ordinary concrete still has the effect of freezing and thawing, resulting in durable structures. Th...
