Construction method for protecting earth drop upper cover support pile slope protection restoration

The invention relates to the field of civil engineering, in particular to a construction method for protecting earth drop upper cover support pile slope protection repair, which comprises the following steps of: 1, mounting a tripod; 2, an operation frame is erected; 2.1, bottom horizontal tubes and vertical tubes are erected; 2.2, the vertical rods are lengthened; step 2.3, preparing a protective barrier; and 3, surface layer repairing is conducted, specifically, after preliminary fixing is conducted, the surface layer of the original metro upper cover supporting pile is repaired, and the concrete strength of the original metro upper cover supporting pile is guaranteed. Construction is conducted through the steps, the problem that the subway upper cover supporting pile cracks due to construction can be effectively solved, and the method is safer and more convenient compared with related technologies. An original subway upper cover supporting pile is of an original building structure and cannot be dismantled.
