A rolling and sliding adaptive device for guiding and fixing a drill pipe includes a mounting platform, where the mounting platform is provided with a through hole for the drill pipe to pass through. Multiple rolling and sliding support mechanisms are arranged around the through hole. The rolling and sliding support mechanisms each include a support seat. The support seat is provided with a contact element telescopic and swingable on the support seat. A telescopic drive mechanism is provided between the contact element and the support seat. The contact elements on the multiple rolling and sliding support mechanisms form a funnel-shaped structure with a large upper part and a small lower part around the through hole. The rolling and sliding adaptive device is used on a deep in-situ high-fidelity coring calibration platform for accurate positioning of an assembly process of a multi-section drill pipe bin.

This application provides a communication method and a communications apparatus. The method can include performing extension based on an existing operation, administration, and maintenance (OAM) packet after an intermediate node in a path of a segment routing traffic engineering (SR-TE) tunnel senses a bit error fault, to support a bit error switching function. That is, the method can include adding, to the OAM packet, identification information used to identify that signal degradation occurs in the SR-TE tunnel. As a result, it is ensured that the SR-TE tunnel supports the bit error switching function of the intermediate node, and a customer service can be effectively prevented from being damaged.
