Anchored concrete retaining wall rock-fill dam and building method thereof

Abstract

The invention discloses an anchored concrete retaining wall rock-fill dam, which comprises a concrete retaining wall and a plurality of anchoring body groups, wherein a rock-fill is arranged behind the concrete retaining wall, and comprises a rock-fill region and a transition region; a horizontal drainage body and a reverse filtering layer are arranged below the rock-fill region; the downstream side of a dam body is provided with a downstream revetment; the anchoring body groups are arranged in the concrete retaining wall, the transition layer and the rock-fill region; the concrete retaining wall consists of a plurality of wall sections; a construction joint is reversed between every two adjacent wall sections; and each construction joint is filled with asphalt mastic. According to the anchored concrete retaining wall rock-fill dam disclosed by the invention, the problems of large filling amount of the rock-fill, large deformation of the dam body and uncoordinated deformation between the rock-fill and anti-permeation bodies existing in the existing dam type are improved effectively. A building method of the anchored concrete retaining wall rock-fill dam comprises the following specific steps of: pouring a concrete retaining wall; filling a rock-fill; and grouting an anchoring body. The building method has the advantages of short construction period, low construction method and simple steps.

Description

technical field [0001] The invention belongs to the technical field of hydraulic engineering, in particular to an anchored concrete retaining wall rockfill dam, and also relates to a construction method of the anchored concrete retaining wall rockfill dam. Background technique [0002] As a water retaining structure commonly used in the field of water conservancy engineering, dams have a very long history. People have used dams to block rivers and store water in the early days to eliminate harm and benefit. The type of dam is compared and selected according to the natural conditions of the dam site, building materials, construction site, diversion, construction period, cost, etc., and can basically be divided into two categories: concrete dams and earth-rock dams. [0003] Concrete dams mainly include three types: gravity dam, arch dam and buttress dam. The gravity dam is a dam type that relies on the friction generated between the dam body's own weight and the foundation to...
