FIELD: underground construction engineering. SUBSTANCE: method involves making stemmed mines or foundation pits, depression of hollow metal members enclosed in cross section, common excavation under their protection, making trough part, waterproofing, installation of columns and top transversal composite metal beams, wall concreting. Novelty is that trough part of lining is made by depression of hollow metal members closed in cross sectional area through ground followed by concreting their voids, after that ground is excavated. EFFECT: reduced labor and material consumption. 2 cl, 3 dwg
