The two control methods for the hydraulic jack can realize double control of force and displacement. In the jacking engineering of large buildings, the weight and the volume of the buildings are large, the more control points are jacked, and the control precision of each control point must be accurately mastered. In the actual jacking process, the jacking of a large building needs to be divided into a plurality of control points, and each control point needs to be synchronously controlled to form resultant force so as to realize double control of force and displacement.
Due to the jacking of the large building, the accurate control of force and displacement is difficult to realize through a hydraulic jack. The key points are as follows: jacking displacement control is difficult; and when the hydraulic system leaks, a safety accident occurs. For the protection of the jack, there are two common methods, one is: the hydraulic jack is not mechanically protected; the second method comprises the following steps: mechanical protection is added, and the mechanical protection has no jacking force and only follows the support (also called following the roof). The following jack is often used in cooperation with a hydraulic jack, and has the advantages of safety and reliability; but has the disadvantages of large volume and high construction cost.
The invention discloses a hydraulic follow-up supporting device, which is a combination of a hydraulic jack and follow-up protection, and is disclosed in Chinese patent No. ZL201310038243. The hydraulic follow-up jack has the advantages that: the hydraulic jack is integrated with the hydraulic jack, and the cost is low.
