Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing.
[0022] Such as figure 1 As shown, the reaction frame is designed according to the size and quantity of the steel wires. Its strength can meet the fatigue of multiple steel wires at the same time. It is welded by steel plates, including the column 5, the brace 12 and the support 4. The diagonal brace 12 is connected and fixed to the support 4, and the side of the column 5 is connected to the hydraulic jack 1, and the hydraulic jack 1 is connected to the oil circuit 2. The number of the columns 5 is two, and the two columns are vertically arranged on the support 4 at intervals. Above, the column 5 has a round hole to connect the anchor 8, the anchor 8 is used to fix the hydraulic jack 1 and the steel wire 7, and the hydraulic jack 1 is also provided with a sensor 9; image 3 As shown, the corrosion circulation container is made up of the corrosion container 6, the circulatio...
