Abstract

The invention discloses a reinforcement structure of an earth-rock dam and a construction method thereof. The structure includes a dam body, the two sides of the dam body are respectively an upstream dam slope and a downstream dam slope, the top of the dam body is a dam crest, and a horseway is arranged on the downstream dam slope , there are several anti-seepage grouting holes arranged vertically at equidistant intervals on the top of the dam, and several anti-slide piles vertically arranged at the horseway, and the bottom ends of the anti-seepage grouting holes and the anti-slide piles protrude The bottom face of the dam body. The invention has the advantages of low risk, simple operation, convenience and practicality, etc., and can be popularized and applied in the field of danger removal and reinforcement of earth-rock dams.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to the field of earth-rock dam risk removal and treatment engineering, and in particular to a reinforcement structure of an earth-rock dam and a construction method thereof. Background technique [0002] At present, there are more than 30,000 dangerous reservoirs in my country, of which earth-rock dam structures account for about 95%, and most of them were built in the 1950s to 1970s. Restricted by the objective conditions at the time, many reservoirs were built without design approval, construction supervision and acceptance in accordance with the basic construction procedures, and there were many problems in terms of safety. Moreover, the problem of poor management in the later period is more serious. Seepage phenomenon is common in many reservoirs, some of them have concentrated seepage, piping, flowing soil and other seepage damage phenomena,...
