　　近日，中车TR280D旋挖钻机在郑阜铁路5标段沈界1号特大桥桩基地质钻探工程中，以出色的施工表现博得了承建方中铁一局以及现场施工人员的一致好评。
　　据介绍，沈界1号特大桥包含郑阜项目1、2号重点控制工程，分别为跨宁洛高速公路钢桁加劲拱连续梁和跨漯阜铁路连续梁转体施工。跨漯阜铁路连续梁转体施工过程中，桩基、承台和现浇梁施工属于临近营业线C类施工，连续梁转体及合拢段施工属于营业线Ⅲ级施工，安全风险等级极高。
　　本次钻探深度为55米，经过多方考量与对比，项目部决定由桩工机械行业的领导者——中车北京重工旋挖钻机承担本次钻探重任。参与施工的TR280D旋挖钻机，最大钻孔直径2500mm、最大钻孔深度可达85m，处理复杂地层施工游刃有余，此次钻探主要探测实际地质情况与设计相符程度、各类地层钻进速度以及旋挖钻在不同地质的机械性能指标、指导桩基机械选型及施工进度安排，确保施工组织安排科学、合理，为后续正式钻孔提供有力的技术支撑和质量保证，为跨既有高速公路及铁路工程防护及过程施工提供安全保证。

　　中车北京重工自2004年第一台旋挖钻机成功下线以来，就一直征战于不同地质施工，克服各种复杂地层，打下了无数个超大、超深桩，凭借其稳定的性能、国际领先的技术水平及完善的售后服务体系享誉海内外。中车北京重工以梦为引，立足本土深入发展，在神州大地创造了无数个奇迹；在国际舞台，中车人挥洒汗水，以“中国创造”赢得市场。公司将通过不断的“深度定制”，升级推动影响力，满足客户多方面的施工需求。并将持续努力为客户提供全方位的施工技术及解决方案，再创辉煌业绩。
