黔中水利六跨连拱现浇支架施工技术

Construction Technology of Brackets for Casting in Place Six-span Arch in Qianzhong Water Conservancy Project

依托黔中水利青年队多跨连拱渡槽项目,为解决山谷大风区,连拱大高宽比施工安全问题,根据现场实际采用钢支撑加贝雷片进行拱圈施工,对支撑体系进行有限元施工过程分析优化支撑结构,通过贝雷片斜搭、异形贝雷片拼装等技术解决连拱支撑问题,具有施工效率高、安全风险低、抗风稳定性好等特点,具有推广应用价值。

Based on Qianzhong Qingniandui aqueduct multi-span arch water conservancy project,for the purpose of a solution to the safety problem of large arcade construction,we used steel braces and Bailey pieces to arch ring construction according to the actual site situation,and made an analysis for optimizing brace system by finite element. The arch support problem was solved through Bailey oblique of special-shaped Bailey piece assembly. With the characteristics of highly efficiency,low-risk,good stability of anti-wind,it is worth expanding and application.
