Prestressed tendon tensioning system and construction method thereof
The invention discloses a prestressed tendon tensioning system and a construction method thereof. The prestressed tendon tensioning system comprises a tensioning jack; the pressure sensor is used for collecting oil pressure in the tensioning jack and is mounted in the tensioning jack; the displacement sensor is mounted at the telescopic end of the tensioning jack so as to collect the elongation of the telescopic end; the hydraulic pump station comprises an oil pipe used for being connected with an oil tank and a proportional valve, a metering pump is installed on the oil pipe, one end of the proportional valve is connected to the oil pipe, and an oil inlet of the tensioning jack is connected to the other end of the proportional valve through a conveying pipe. An oil outlet of the tensioning jack is connected to the other end of the proportional valve through a return pipe, and a one-way valve is installed on the conveying pipe. And the controller is connected to the pressure sensor, the displacement sensor, the metering pump and the proportional valve. The prestressed tendon tensioning system solves the problem that the control accuracy of the tensioning control stress of an existing prestressed tendon tensioning system is not high.
本发明公开了一种预应力筋张拉系统及其施工方法，包括：张拉千斤顶；用于采集所述张拉千斤顶内的油压的压力传感器，安装于所述张拉千斤顶内；位移传感器，安装于所述张拉千斤顶的伸缩端以采集所述伸缩端的伸长量；液压泵站，包括用于连接油箱的油管和比例阀，所述油管上安装有定量泵，所述比例阀的一端连接于所述油管，所述张拉千斤顶的进油口通过输送管连接于所述比例阀的另一端，所述张拉千斤顶的出油口通过回流管连接于所述比例阀的另一端，所述输送管上安装有单向阀；控制器，连接于所述压力传感器、所述位移传感器、所述定量泵、所述比例阀。本发明解决了现有的预应力筋张拉系统的张拉控制应力的控制精准度不高的问题。
