Cut the concrete blocks in sections, no larger than 500 kg each, and then unload them onto the floor below or the ground level.

(2) Based on the design drawings, the cutting area was determined. First, the required cutting edges were marked on the floor slab using ink lines. Then, the size of the floor slab sections was decided according to the lifting equipment, approximately 1.5m x 1.5m.

(2) Clean up and clear the cutting area, including the removal of ground buildings and decorative waste, as well as various pipelines that affect cutting (such as ventilation pipes, electrical conduits, and rainwater pipes).

(3) The perimeter of the slab is cut using a flat-push electric cutting machine, while the central section is fixed to the cutting surface with expansion bolts to accommodate the track of a small cutting machine, enabling segmented cutting.

(4) Prior to the floor cutting of the main structure, a truss-type lifting crane is made from H-beams, which is then securely fastened to the beams.

Four evenly spaced holes are drilled on the sections of the building to be cut, with steel wire ropes threaded through. The ropes are then attached to the hooks of two hand winches, and the concrete cutting sections are lifted onto the hoisting frame.

Tighten the hand winch to ensure full tension.

(6) Utilizing reinforced concrete cutting machines, with specialized personnel on-site to oversee the construction process.

After cutting, two hand-cranked winches are used to gently hoist the cut floorboards and lower them safely to the lower level or ground floor.
