隧道单侧加宽波纹钢板快速拼装技术研究
Rapid assembly technology of corrugated steel plate for single-side widening of tunnels
摘要
Abstract
To address the challenges such as significant surrounding rock disturbance,complex construction procedures,and long construction periods in single-side widening during the reconstruction and expansion of highway tunnels in China,this study took a typical highway tunnel reconstruction and expansion project as an example to investigate the rapid assembly technology of corrugated steel plate lining.A complete technical system was proposed,encompassing lining structure design,rapid ring-by-ring assembly techniques,and construction monitoring and control.The technology utilized a box-type corrugated steel plate lining structure.Rapid and precise circumferential and longitudinal assembly was achieved through groove-protrusion connections.Combined with an optimized construction method of"pre-reinforcement+block-by-block excavation",this technology significantly improved construction efficiency and effectively controlled surrounding rock deformation.The research results demonstrate that this technology offers advantages such as convenient construction,a short construction period,minimal disturbance to surrounding rock,and high structural stability.It can ensure construction safety and control surrounding rock deformation.This study provides valuable reference for the design and construction of similar tunnel reconstruction and expansion projects.关键词
