Abstract
For overcoming the lining construction difficulties and improving construction efficiency of spillway tunnel of Dagan-gshang Hydropower Station, we develop a new lining trolley that is suited for lining construction characterized as steep slope, large cross-section, normal concrete grouting and complicated transition sections. The innovations for the lining trolley involve self-lift concrete pouring system and auto-heightening device for top template. In the construction trials, the new innovations have fulfilled the requirements of tunnel lining construction, realizing one-time lining for large cross-section successfully.关键词
