三峡升船机液压自升式模板施工技术

Construction technology of Three Gorges Project ship lift hydraulic self-climbing formwork

三峡升船机塔柱混凝土施工工期紧,精度要求高,为保证施工进度和质量,采用了液压自升式模板。本文重点介绍了三峡升船机塔柱混凝土液压自升式模板施工技术、自升式模板改进措施以及为满足自升式模板上升而在塔柱板梁、牛腿处进行的结构处理措施。实践证明,液压自升式模板施工技术的应用与改进满足了三峡升船机塔柱筒体混凝土的设计要求,有效地提高施工效率、节约了成本,保证了工程质量并提高施工的安全性,可为其他水电工程施工提供借鉴。

The construction time limits for the tower column concrete of Three Gorges Project ship lift is pressed for time and require high accuracy. In order to ensure the construction progress and quality, the hydraulic self-climbing formwork is used. This paper focuses on the construction technology of hydraulic self-climbing formwork, improvement measures of self-climbing formwork as well as structural measures made in the plate girders and corbels department of tower to meet the rising-up of self-climbing formwork on Three Gorges Project ship lift tower column concrete. It has been found that application and improvement of the hydraulic self-climb-ing formwork construction technology meet the design requirements of the tower column cylinder concrete of the Three Gorges ship lift, effectively improve the construction efficiency, save cost, ensure the engineering quality and improve the safety of the construction, can orovide reference for other hvdrooower project construction.
