Abstract

The invention relates to a 300-meter high dam, comprising a cemented sand gravel dam and a concrete face rockfill dam, the cemented sand gravel dam is located at the upstream low position of the dam, and has a construction height of 70-100 meters; the concrete The face rockfill dam is located on the cemented sand and gravel dam, with a construction height of 200-230 meters; cementitious gravel concrete. The invention has the advantages of saving material resources, protecting the ecological environment, and good stability of the dam.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a 300-meter high dam and its construction technology. Background technique [0002] A dam is a water-retaining structure used to intercept the water flow of a river to raise the water level or adjust the water volume. Dams can be divided into two categories: concrete dams and earth-rock dams; concrete dams generally refer to dams made of concrete pouring (or rolling) or assembled with prefabricated concrete blocks, and earth-rock dams generally refer to dams made of local soil, stone or mixed materials. , the retaining dam built by throwing filling, rolling and other methods, when the dam body material is mainly soil and gravel, it is called an earth dam, and when it is mainly gravel, pebbles, and blasting stones, it is called a rockfill dam; When the two types of local materials account for a considerable proportion, it is called an earth-rock mixed dam. ...
