PROBLEM TO BE SOLVED: To provide a reaction member for jacking equipment.SOLUTION: A reaction member for jacking equipment is provided within a jacking pit to bear a repulsive force of the jacking equipment, in a jacking method for constructing a pipeline in the ground. In the reaction member for the jacking equipment, one surface is formed to be brought into intimate contact with an inner surface of the jacking pit, and the other surface is formed of a flat plate with a predetermined thickness so as to be brought into intimate contact with a rear end of the jacking equipment. Thus, the reaction member for the jacking equipment makes construction performed rapidly and simply. A pipeline jacking method employs the reaction member. |
