| description | The invention relates to a soft rock chamber floor heave treatment supporting method which comprises the following steps that a reinforcing mesh is laid on an excavated chamber bottom plate, and concrete is sprayed to form a concrete surface layer; a plurality of steel beams are arranged on the concrete surface layer in the transverse direction of the chamber, concrete is poured, a set interval is formed between every two adjacent steel beams, and the steel beams and the concrete jointly form a supporting layer; multiple sets of supporting pipes attached to the upper surface of the supporting layer are laid, the multiple sets of supporting pipes are longitudinally arranged along the chamber, the two ends of each supporting pipe are fixed to the side wall of the chamber through fixing parts and anchoring parts, and the anchoring parts are inserted into the surrounding rock; by the adoption of the method, the supporting effect is good, and the construction speed is high.
