Anti-floating bag type anchor rod prestress detection system and detection method
The invention relates to an anti-floating bag type anchor rod prestress detection system which comprises a twisted steel bar, a tensioning end plate is arranged at the upper end of the twisted steel bar, a pre-tightening device is arranged on the upper surface of the tensioning end plate, and a detection sensor is arranged above the pre-tightening device. The detection sensor is parallel to the twisted steel, the two ends of the detection sensor are fixedly connected with the twisted steel, a main end plate is arranged above the detection sensor, a main nut is arranged above the main end plate, the main nut is in threaded connection with the twisted steel, a raft plate is arranged above the tensioning end plate, and the end of the twisted steel is located in the raft plate; the detection sensor is connected with a cable extending out of the raft, and the prestress of the twisted steel is distributed on the twisted steel below the pre-tightening device before the construction of the raft is completed; after the raft is constructed, the pre-stress of the twisted steel is transmitted to the twisted steel part corresponding to the detection sensor through the loosening pre-tightening device. The device has the effect that the prestress formed by the tensioning force of the twisted steel can be detected.
本申请涉及一种抗浮囊式锚杆预应力检测系统，其包括螺纹钢筋，螺纹钢筋的上端设置有张拉端板，张拉端板的上表面设置有预紧装置，预紧装置的上方设置有检测传感器，检测传感器平行于螺纹钢筋并且检测传感器的两端与螺纹钢筋固定连接，检测传感器的上方设置有主端板，主端板的上方设置主螺母，主螺母与螺纹钢筋螺纹连接，张拉端板的上方设置有筏板，螺纹钢筋的端部位于筏板的内部，检测传感器连接有伸出于筏板的电缆，筏板完成施工前螺纹钢筋的预应力分布在预紧装置下方的螺纹钢筋上；筏板完成施工后，通过松脱预紧装置使螺纹钢筋的预应力传递到与检测传感器对应的螺纹钢筋的部位。本申请具有使螺纹钢筋张拉力形成的预应力能够进行检测的效果。
