Synchronous jack introduction
The hydraulic synchronous lifting system is equipped with safety measures such as anti-electromagnetic interference, misoperation locking, hydraulic pipeline self-locking due to pressure loss, clamp reverse movement self-locking, overload alarm and other safety measures to ensure smooth, safe and reliable lifting. Reliable construction technology. Each lifting point of the system can automatically adjust the height difference during construction, which has the advantages of high synchronization accuracy, high construction efficiency, economy and practicality.

Attention to when prestressed anchors are tensioned

1. Before tensioning, check whether the reserved holes are unobstructed and whether there is any leakage of slurry in the corrugated pipe. If there is a leakage of slurry to block the pipeline, it must be clear. In particular, the bell mouth parts of the anchor pads at both ends of the tunnel should be cleaned up.
2. The steel strand should not be severely corroded. If there are rust pits and pitting, the strength of the steel strand will be reduced, and the broken wire will appear during tensioning. In the tension anchoring area, the floating rust and cement slurry mud sand on the steel strand should be cleaned up so as not to affect the anchoring.
3. The anchor ring clip must be properly kept at the construction site, moisture-proof and rust-proof, especially if the teeth of the clip are seriously corroded, they should be stopped. When the anchor ring clip is used, it should avoid sticking with mud and sand.
4. The jack, oil pump, and oil pressure gauge should be calibrated before use. If the oil pressure gauge is bumped or replaced with a new gauge during use, it should be re-calibrated. When the deviation between the tensile length and the design amount is large, the accuracy of the pressure gauge should be considered. Jack is strictly prohibited from no-load afterburner.
5. When using tool anchors, be sure to coat a layer of paraffin on the outer cone surface of the tool anchor clips so that the anchors can be pulled back.
6. The steel strand between the tool anchor and the tool anchor cannot cross, otherwise the anchoring will be affected.
