中国土木工程学会预应力技术开发咨询部在山东齐鲁石化公司胜利炼油厂大型催化裂化器设备基础加固中,首次提出采用后张无粘结预应力混凝土新技术,节省直接加固费47万元,缩短工期5天,为国家增收利税560万元,获得了成功。 齐鲁石化公司于1987年确定对该项装置进行技术改造。按设计要求,原基础要增加垂直
The Prestressing Technology Development Consulting Department of the China Civil Engineering Society has proposed the new technology of post-tensioned unbonded prestressed concrete for the first time in the reinforcement of the large-scale catalytic cracker equipment in the Shengli Oil Refinery of Shandong Qilu Petrochemical Company, saving direct reinforcement costs by RMB 470,000. The duration of the project was five days, and the country’s revenue and taxes increased by 5.6 million yuan, which was a success. Qilu Petrochemical Company decided in 1987 to carry out technological transformation of the device. According to design requirements, the original foundation should be increased vertical
