 How does intelligent tensioning work?

Intelligent tensioning construction operation process
The first is to calibrate the tensioning equipment, place the equipment, install the oil top, connect the oil pipe, connect the power supply - turn on the pump to preheat, exhaust the air, check the network status, and confirm that the displacement data line connection is normal;
The second is to input the oil top, and the calibration coefficient of the pressure sensor is input to the relevant tension parameters of each channel of the component beam. Set the tension mode (single roof, multiple roofs, common beam, continuous long beam, 50% segmented tension, etc.)
The third is to input the tensioning number and retrieve the beam and slab parameters, the system automatically calculates the tension control force at all levels, and the operator enters the control interface after checking that the data is correct
The fourth button starts automatic tensioning, the system collects the pressure displacement information of the main and auxiliary machines in real-time and completes the tensioning step by step according to the set load holding time and target pressure
The fifth system calculates and displays the elongation of the steel strand in real-time, and judges in real time whether the error of the theoretical elongation is within 6%--the automatic pressure relief return is performed if the elongation is within 6%, and the exceeding interface will pop up if the elongation is less than 6% For over-sheeting, also switch to the automatic pressure relief return, and finally query and print the tensioning record.


The intelligent system realizes the intelligent control of the tensioning program, which is not affected by human and environmental factors: the tensioning process flow such as the intermediate holding time and the endpoint holding time fully meet the requirements of the bridge design and construction technical specifications, reducing the prestress during the tensioning process Loss. The wireless networking of the CNC hydraulic pump main control station, each CNC hydraulic pump sub-station, and data monitoring laptop computer eliminates complicated cable wiring and facilitates movement on the construction site. Complete all automatic tensioning control operations with one key, automatically generate a tensioning record sheet and print out a tensioning record report in the format required by the owner. Eliminate the possibility of artificial fraud, and also save the calculation and filling process of data such as tension and elongation, reduce the labor intensity of construction personnel, and improve work efficiency.
