摘要
巴塘水电站导流洞渐变段顶拱受不良地质条件的影响出现了塌方,由于工期紧,若采用传统平面大模板浇筑边墙的方式其施工工期不能够满足导流目标要求。阐述了该工程应用钢模台车成功地完成导流洞进口渐变段边墙混凝土衬砌施工的过程,较平面大模板节约工期6 d,其混凝土外观质量优于平面大模板衬砌渐变段边墙混凝土,不仅节约了施工成本,而且为灌浆争取了时间,所取得的经验可为类似工程借鉴。
The top arch of the transition section of the diversion tunnel of Batang Hydropower Station collapsed due to the adverse geological condition.Due to the tight construction schedule,the diversion target couldn't be complete if the traditional flat large formwork to pour the side wall were used.This paper expounds that the concrete lining construction of the side wall of the inlet transition section of the diversion tunnel in this project was successfully completed,and 6 days were saved compared with the flat large formwork lining plan.The appearance and quality of the concrete is better than the flat large formwork plan.The application of steelshuttering trolley not only saves the construction cost,but also saves the time for the grouting.The obtained experience can provide reference for similar projects.
