Non-excavation and top drilling combined crossing and spanning pipeline laying method

The invention provides a non-excavation and top drilling combined crossing and spanning pipeline laying method. The method comprises the steps of carrying out pipe-jacking construction and horizontal directional drilling construction at the same time; getting through the position, where pipelines are to be laid, at the bottom of a receiving shaft; then, enabling the pipelines to communicate with each other; and finally, carrying out backfilling, so as to achieve pipeline laying. According to the method, the part, difficult to construct through a horizontal directional drilling machine, of a pipeline construction zone of a complex stratum is selected as a pipe-jacking construction section, other complex stratums are adopted as horizontal directional drilling machine construction parts according to reconnaissance information, the one-time crossing distance is long, the constructable pipe diameter is large, large-diameter long-distance pipelines can be laid in the complex stratums through one step, construction cost is greatly reduced, and construction time is greatly saved.
