1. An assembly method for a in-situ coring calibration platform, comprising the following steps:
S1: fixing a core bin assembly subsystem on a preset ground foundation and fixing a simulator of a core bin on a mounting base plate of the core bin assembly subsystem;
S2: driving a cylinder, wherein a piston end of the cylinder drives the mounting base plate to move on a Y-axis until a preset position;
S3: driving a servo motor and controlling, by two manipulators, two clips to move closer to each other along the simulator to support and fix the simulator of the core bin;
S4: fixing a drill pipe bin assembly subsystem on the ground foundation, wherein the drill pipe bin assembly subsystem is provided on an X-axis perpendicular to the Y-axis;
S5: assembling multiple sections of a drill pipe bin in turn based on a length of a drill pipe to form a complete drill pipe bin; aligning and connecting, after assembly, a bottom of the complete drill pipe bin to the simulator of the core bin, and aligning and communicating a top of the complete drill pipe bin with a lower part of an adaptive drill pipe guide structure; and
S6: driving the adaptive drill pipe guide structure to perform positioning for an assembly of the drill pipe bin in the X-axis and perform an adaptive guidance for an assembly of the drill pipe.
