Super-large-scale water conservancy project and construction technology thereof

Abstract

The invention discloses a super-large-scale water conservancy project and a construction design scheme thereof, and aims to provide a water conservancy project construction technical scheme which is greater in water transfer scale and quicker in investment return, and further has the benefits of flood discharge, power generation (including a power transfer peak for pumped storage power generation), transportation and the like. A stepped type or relay type underground continuous wall group technology is adopted to dig and build a deep canal; dug-out soil, sand and the like are used for boosting mud flat to make land or encircling the sea (or a river or a lake) to make land or building an ultra-wide river wall to make construction land; according to a super-large-scale water conveying (transferring) pipeline resistant to ultra-high pressure, a reinforcing frame consisting of triangles is arranged above (or in) the pipeline top wall; and soil, sand and the like which are produced by ditching are filled into wall groups on the pipeline to make land, press and fix the pipeline. According to the super-large-scale water conservancy project and the construction design scheme thereof disclosed by the invention, the economic benefits and the social benefits are obviously greater than those in a current technical scheme.

Description

technical field

[0001] The invention belongs to the technical field of water conservancy engineering, specifically to the technical field of water conservancy engineering and its construction mainly for ultra-large-scale water diversion (in addition, functions such as flood discharge, power generation, water storage, breeding, shipping, etc.). Background technique

[0002] The largest existing water diversion project is China's South-to-North Water Diversion Project, which transfers part of the abundant water resources in the Han River Basin to North China and Northwest China. project. The purpose of the project is to promote the coordinated development of economy, society, population, resources and environment in the north and south of China. The South-to-North Water Diversion Project has three water diversion lines: the east route, the middle route and the west route, with a total investment of 500 billion yuan. The east route project is located in the east. Due to the l...
