Tensioning equipment technology mainly has the following characteristics

Intelligent tensioning equipment technology mainly has the following characteristics:

(1)High precision: intelligent tensioning technology can obtain the required precise prestress value through computer operation, and its accuracy is as high as ±1%;

(2)Can realize the "double control" stipulated in the construction specifications: the sensor in the intelligent drawing system can collect the elongation data of the strand in real time, and upload it to the computer to automatically calculate the elongation data, and then check the elongation data in time (whether it is within the range of ± 6%), so as to realize the "double control" of the prestress and elongation synchronization;

(3) Multi-top symmetrical tensioning: that is, a computer performs simultaneous and synchronous symmetrical tensioning on two or more jacks;

Intelligent control: this is one of the most obvious features of traditional tensile technology, not affected by human or environmental factors, the construction stop point, loading speed and duration can be strictly in accordance with the design and construction specifications of prefabricated beams;

(4) Remote monitoring: owners, supervisors, construction and testing units can monitor and interact through the same Internet platform to timely grasp the quality of bridge prestressed construction, which is more conducive to project quality management and traceability.

Use intelligent tensioning system for maintenance

The initial use of intelligent tensioning equipment should be carried out under the on-site guidance of relevant technicians. After the technicians and operators of the project department master the intelligent tensioning technology and operating procedures, and meet the requirements of the intelligent tensioning system operating procedures, the project technicians can carry out intelligent tensioning operations independently.

Assign special personnel to manage and maintain the equipment. During the summer tensioning construction, the equipment is covered with solar umbrellas, and the tensioning operation in high temperature and rainy days is avoided as far as possible. During high temperatures, work should be arranged in the morning and evening. When the equipment is not in use, the tarpaulin should be covered or moved to the warehouse for safekeeping, to prevent the equipment from being exposed or raining, and to ensure the accuracy and service life of the equipment.
