大吨位先张法预应力混凝土薄壁“U”形梁全自动智能张拉技术

Automatic and Intelligent Tensioning Technology of Large-tonnage Pre-tensioned Prestressed Concrete Thin-walled"U"-Shaped Beams

针对传统大吨位先张法预应力张拉存在的施工工效低、控制精度不高、安全风险高等弊端,全新设计全自动智能张拉系统,包括轴压柱张拉台座、全自动智能张拉系统、智能油泵等,经工程实践验证该技术较为成熟、先进。

Aiming at the disadvantages of low construction effi ciency,low control accuracy and high safety risk of the traditional large tonnage pretensioning method,newly designed automatic intelligent tensioning system,it includes axial compression column tensioning pedestal,automatic intelligent tensioning system,intelligent oil pump,etc,the engineering practice shows that the technology is relatively mature and advanced.
