The utility model discloses a counter-force support system for pipe jacking construction, which is characterized in that a counter-force wall, a backrest and a counter-force support are sequentially arranged in a starting well along a pipe jacking tunneling direction, the counter-force wall is rigidly connected with two side walls of the starting well, and the backrest is rigidly connected with the counter-force wall; the counter-force support is fixedly installed on a bottom plate laid on the ground of a starting well, one end of each jacking device installed on the counter-force support is connected with the jacking iron so as to push the duct piece to tunnel, and the other end of each jacking device abuts against the rear backrest. A counter-force system formed by the counter-force support, the rear backrest, the counter-force wall and the two side walls of the starting well can provide enough counter-force, the counter-jacking force generated in the jacking process of the jacking pipe can be evenly distri
