南水北调一期穿黄隧洞工程规模宏大,是多个工作面同时施工、多种施工技术共同运用的综合工程。本文就其超深连续墙施工、盾构进出洞端头地层加固、盾构始发、过河隧洞长距离掘进、泥水长距离输送、邙山段大坡度推进、预应力混凝土二次衬砌及施工期安全度汛等穿黄隧洞工程的难点提出了施工对策。
The South-to-North Water Diversion Project, a project of crossing the Yellow River, has a grand scale and is a comprehensive project where multiple work surfaces are constructed simultaneously and various construction technologies are used together. In this paper, the construction of its ultra-deep continuous wall, shield tunnel entrance and formation of the end of the reinforcement, shield the origin, long-distance tunneling across the river, long-distance transport of muddy water, large slope Pingshan advance, prestressed concrete secondary lining and construction Flood season and other flood safety projects such as the difficulty of the Yellow tunnel proposed construction measures.
