There was a problem of cracking or generating uniformity by eating the

In addition, real-time sensing of displacement due to large longitudinal and lateral gradients of the bridge structure or bending deformation of the upper structure of the bridge, and in response to this, automatically adjust the lifting height of hydraulic cylinders and hydraulic jacks under intelligent control in a multi-channel method There is no controllable device and method, and since the operator has to manually monitor the work space while walking around, the bridge support replacement work takes a long time and requires many workers, so the bridge support replacement work cost is also expensive. there was.
