Overview
Service overview
Shield Tunnel Structural Strengthening Steel Ring Reinforcement Services are designed to improve the stability and safety of shield tunnel structures. Based on defect identification and grading, steel ring reinforcement is implemented for tunnel segments with severe convergence, damage or structural risks.
The process includes steel ring production, pre-installation preparation, segment hoisting, steel ring assembly, welding, grouting and anti-corrosion and rust-proof treatment. The reinforcement method improves structural stiffness, helps control deformation and supports the safe operation of metro shield tunnels.
JingSui owns a proprietary steel ring processing and manufacturing production line and has developed standardized steel ring reinforcement procedures. The service can be combined with intelligent inspection, defect grading and maintenance management to provide an integrated structural reinforcement solution.
盾构隧道结构钢环加固服务用于提升盾构隧道结构稳定性和安全性。基于病害识别和分级结果，对存在严重收敛、破损或结构风险的管片区段实施钢环加固。
施工流程包括钢环生产、安装前准备、管片吊装、钢环拼装、焊接、注浆以及防腐防锈处理。钢环加固可提升隧道结构刚度，帮助控制变形，并支撑地铁盾构隧道安全运营。
精隧科技拥有自主钢环加工制造生产线，并形成钢环加固标准化施工流程。该服务可与智能检测、病害分级和维保管理结合，提供一体化结构加固解决方案。
