CDM锚预应力体系是重庆交通学院桥新技术研究所和解放军5701厂全作开发的一种预应力效率高、技术性能好的预应力体系。该体系是现行DM镦头锚预应力体系的改进与更新。1996年4月通过了阶段性试验。1997年1月经交通部重庆公路工程检测中心检验认定:CDM锚具可批量生产,可广泛用于桥梁、工民建、港口、电站及其他土建工程。
CDM anchor prestressed system is a prestressed system with high prestressing efficiency and good technical performance developed by Bridge New Technology Research Institute of Chongqing Jiaotong University and 5701 Factory of People’s Liberation Army. This system is the improvement and renewal of the current DM upsetting anchor prestressing system. In April 1996 passed the phased test. In 1997 January by the Chongqing Highway Engineering Testing Center of the Ministry of Transportation found that: CDM anchors can be mass-produced, can be widely used in bridges, civil construction, ports, power stations and other civil works.
