The block hoisting technology for cultural relic sites is to reconstruct the site support system by horizontally and closely arranging steel pipes pushed in at a position ≥ 0.5m from the bottom of the site and setting horizontal H-shaped steel below the steel pipes, which makes the site bear the force on the force-bearing system composed of the steel pipes and H-shaped steel, and ensures the reliable support during the subsequent jacking-up and moving process of the site. At the same time, steel plates and channel steels are welded outside the site at a distance of ≥ 0.5m around it to form a stable and reliable protection system for the site, preventing secondary damage to the site during the jacking-up and moving processes. Track beams and tracks are constructed below the H-shaped steel of the site. The PLC hydraulic jacking system is used to synchronously jack up the entire site as a whole, and the force on the site is transferred to a new support system consisting of the track beams + tracks + H-shaped steel + steel pipes through jacks. The site is disassembled into blocks by the minimally invasive cutting and separation technology, and the site is hoisted onto a transport vehicle by using lifting machinery and transported to the resettlement site for dismantling and protection.
