市域郊铁路高架区间挂篮悬臂浇筑施工技术应用研究

Research on the Application of Construction Techniques for Cantilever Cast-in-Situ Concrete Structures in Elevated Sections of Suburban Railway Lines

摘要

围绕市域郊铁路高架区间受限施工条件，结合某工程，分析挂篮悬臂浇筑在结构设计、工艺控制、质量安全监测中的应 用。结果表明，该技术使工期由120 d缩短至90 d，成本由500万元降至450万元，梁体线型偏差合格率达98%，混凝土强度 检测合格率达100%，具备较好的效率与质量控制效果。

Abstract

Addressing the challenging construction conditions of elevated sections in suburban railway projects, this study examines the application of hanging basket cantilever casting in structural design, process control, and quality/safety monitoring through a specific case. Results demonstrate that this technique reduced project duration from 120 days to 90 days, lowered costs from 5 million yuan to 4.5 million yuan, achieved a 98% compliance rate for beam profile deviations, and maintained a 100% pass rate for concrete strength tests, demonstrating excellent efficiency and quality control performance.
