  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The reaction force member for propulsion equipment of the present invention is a propulsion method for constructing the pipe line 30 in the ground, and is provided inside the start pit 10 to support the reaction force of the propulsion equipment 40. As shown in FIGS. 1 to 8, one surface is formed so as to be in close contact with the inner surface of the start pit 10, and the other surface is a flat surface having a predetermined thickness so that the rear end of the propulsion equipment 40 is in close contact. The face plate 110 is formed. Such a flat plate 110 is formed as small as possible within a range in which the propulsion equipment 40 can be supported.

When such a flat plate 110 is used for the start pit 10 excavated in a circular shape, the mortar 50 cured in a round curved surface so as to be in close contact with the inner surface of the start pit 10 is formed, or A round curved plate 120 is formed on one surface of the face plate 110 so as to be in close contact with the inner surface of the starting pit 10 excavated in the circular shape. The curved plate 120 is formed according to three or more kinds of standards according to the size of the start pit 10 and the curved surface.

A rubber plate 130 is attached to the outer surface of the curved plate 120 so as to be in close contact with the inner surface of the start pit 10.

  In the space between the flat plate 110 and the curved plate 120, the mortar 50 is laid and then cured so as to support the repulsive force, or the supporting force is improved, or a large number of supporting rods 150 or honeycombs are provided. The partition 160 is formed to improve the supporting force. A large number of support rods 150 are formed on the left and right and top and bottom.
