The invention discloses a suspended self-support type piling method and a piling
machine. The suspended self-support type piling method comprises the following steps: forwards extending a first main beam and a second main beam, and suspending a front-end supporting joining beam above a to-be-constructed
pile foundation; horizontally mounting the to-be-constructed precast
pile on the front side surface of a stand column
tower frame, and fixing the to-be-constructed precast
pile; starting an amplitude-varying
winch, shortening a distance between a first slide wheel and a second slide wheel, realizing amplitude varying of the stand column
tower frame; while amplitude varying of the stand column
tower frame achieves a predetermined amplitude-varying angle, extending an amplitude-varying telescopic oil cylinder, and rotatably connecting a second slide support base with an amplitude-varying oil cylinder fixing base through a movable
insertion pin; and shrinking the amplitude-varying telescopic oil cylinder, and lifting the stand column tower frame to a predetermined angle which corresponds to the to-be-constructed pile foundation. The key point of the suspended self-support type piling method is that the original bridging mechanism is utilized to perform
collaborative design of the process and equipment for suspended piling for a heavy ultra-long precast pile, structure collaborativedesign of a bridging
machine and the piling
machine is also performed, a supporting position at the front end does not need to provide, the construction cost is reduced, and progress of works is improved.
