Abstract: A conduit tunnel supplies water for three units,the higher intake tower and shaft,larger diameter of tunnel and penstock,poor geological condition features largely in the system.By study we have adopted many new construction technologies and tech-niques to get better effect in rapid constructing,good quality and putting into operation ahead.This paper summarizes the experi-ence of construction and quality control.?

摘要： 引子渡水电站发电引水系统为一洞三机供水方式，该引水系统的塔、井结构相对较高，隧洞及钢管直径大、地质条件差和工期紧为其特点，经施工中不断探索，采用多种新技术、新工艺，终于取得了建设速度快、质量好和提前投产的良好效果，本文对其施工和质控要点予以总结和介绍，以期达到相互交流之目的。
