Self-adaptive bidirectional jacking pipe jacking construction method

The invention discloses a self-adaptive two-way jacking pipe jacking construction method, and belongs to the technical field of pipe jacking construction. The method comprises the following steps: S1, surveying and setting out, and excavating a starting well and a receiving working well; s2, a jack is installed; s3, a pipe jacking machine is installed, and a pipeline and jacking iron are placed; s4, bidirectional jacking construction is carried out; and S5, after jacking construction is completed, the equipment is dismantled, and the landform is restored. A set of pipe jacking machines is adopted, the pipelines are arranged on the two sides of the pipe jacking machines correspondingly for jacking, due to the change of resistance borne by the two sides of the pipe jacking machines, the two ends of the pipe jacking machines alternately change between the fixed ends and the jacking ends, and self-adaptive synchronous jacking construction of the pipelines on the two sides is achieved; according to the constructio
