Prestress detection method and non-grading rapid continuous tensioning method and system
The invention belongs to the technical field of tensioning equipment, and particularly discloses a prestress detection method and an ungraded rapid continuous tensioning method and system.The continuous tensioning method includes the steps that a tensioning system is installed, self-inspection is conducted, the tensioning system is started for tensioning, and stress strain and flow information is collected in real time; a stress displacement curve F-S, an average stress total displacement curve F < average >-S < total >, a stress time curve F-T and a displacement time curve S-T are generated in real time according to the collected stress values and strain values, the elongation amount is calculated in real time, after tensioning is conducted to a preset force value, a high-position load holding stage is started, the load holding time is set in advance, and after the load holding time is finished, the stress displacement curve F-S, the stress time curve F < average >-S < total >, the stress time curve F-T and the displacement time curve S-T are obtained. And after the load holding is completed, the tensioning system automatically unloads and returns oil. By the adoption of the technical scheme, automatic collection, continuous collection and automatic elongation calculation are achieved, and non-grading rapid and continuous tensioning is achieved.
本发明属于张拉设备技术领域，具体公开了一种预应力检测方法、不分级快速连续张拉方法及系统，连续张拉方法通过安装张拉系统并自检，启动张拉系统进行张拉，实时采集应力应变及流量信息，所采集的应力值与应变值实时生成应力位移曲线F‑S、平均应力总位移曲线F均‑S总、应力时间曲线F‑T、位移时间曲线S‑T，并实时计算伸长量，张拉至预设力值后，进入高位持荷阶段，预先设置持荷时间，至持荷时间结束，持荷完成后张拉系统自动卸荷、回油。采用本技术方案，自动采集、连续采集、自动计算伸长量，实现不分级快速连续张拉。
