铁路混凝土桥梁加固施工技术

Study on Construction Technique of Strengthening Concrete Railway Bridge

通过对包神铁路桥梁加固中对桥梁情况进行详细分析,采用了体外预应力加固法、粘贴钢板加固法,并引进了低回缩锚具、聚合物混凝土等新材料,大大提高了桥梁的整体刚度和稳定性,达到了预期效果。

The existing bridge requires high strengthening technology and has great difficulty in construction. Based on the condition analysis for bridge, the integral rigidity and stability of the bridge were greatly improved by the Baoshen railway bridge reinforcement with outside pretressing and stick steel strengthening method, new materials of low anchorage and polymer concrete, which achieved good effects. This article briefly introduced crack treatment techniques and planting bar techniques.
