Stiff core composite pile combined construction equipment and construction method

The invention relates to the technical field of underground engineering mechanical equipment, in particular to stiffness core composite pile combined construction equipment and a construction method. The equipment comprises a working platform, a tower, a crane and a pile pressing mechanism; the tower comprises a tower body, a first bidirectional stirring mechanism and a second bidirectional stirring mechanism; the tower body can move horizontally in the axial direction through the tower moving slide way and is connected to the working platform. The first bidirectional stirring mechanism and the second bidirectional stirring mechanism are respectively connected and hung on the tower in a lifting and sliding manner; the crane is used for hoisting the core pile; the pile pressing mechanism is used for core pile implantation after stirring pile construction is finished. The device has the advantages that drill rod connection and relay piling actions can be completed by horizontally sliding on the working platform
