Protection device of prestressed uplift pile steel strand stress sensor
The invention relates to a protection device for a prestressed uplift pile steel strand stress sensor, which comprises a reinforcement cage, a plurality of pile top leveling layer pile body main reinforcements are uniformly inserted into the top end of the reinforcement cage, and a plurality of unbonded steel strands are uniformly bound in the reinforcement cage. The outer wall of the bottom end of the unbonded steel strand is sleeved with a pile bottom pressure sensor and a pile bottom P-type extrusion anchor, the pile bottom pressure sensor is located above the pile bottom P-type extrusion anchor, and the outer wall of the top end of the unbonded steel strand is sleeved with a pile top pressure sensor and a pile top clamping piece type anchorage device. When the protection device of the prestress uplift pile steel strand stress sensor is used, the pile bottom pressure sensor can be protected through the first protection shell, the pile top pressure sensor can be protected through the second protection shell, and therefore the sensors are not prone to being affected by the external environment and operators when used, and the safety of the sensors is improved. The risk of damage and misoperation can be reduced, and the requirement for accurate and stable stress monitoring of the prestressed uplift pile steel strand can be met.
本发明涉及一种预应力抗拔桩钢绞线应力传感器的保护装置，其包括钢筋笼，钢筋笼的顶端均匀插接有数个桩顶找平层桩身主筋，钢筋笼的内部均匀绑扎有数个无粘结钢绞线，无粘结钢绞线的底端外壁套设有桩底压力传感器和桩底P型挤压锚，桩底压力传感器位于桩底P型挤压锚的上方，无粘结钢绞线的顶端外壁套设有桩顶压力传感器和桩顶夹片式锚具；该预应力抗拔桩钢绞线应力传感器的保护装置在使用时，通过第一保护壳能对桩底压力传感器进行保护，通过第二保护壳能对桩顶压力传感器进行保护，从而使传感器在使用时不易受到外界环境和操作人员的影响，能够降低损坏性和误操作的风险，能满足预应力抗拔桩钢绞线应力监测准确和稳定要求。
