PURPOSE: An installation method of a ground subsidence-proofing and waterproofing wall for an underground structure is provided to execute a construction work easily and to complete large quantity of construction works effectively for a short term. CONSTITUTION: The installation method of a ground subsidence-proofing and waterproofing wall for an underground structure comprises the steps of: when installing a ring or rectangular H-beam(8) by pressing an excavator(7) with a propulsion jack(1) and excavating the ground for installing an underground structure, attaching a ground subsidence-proofing woven fabric plate(7) temporarily inside a rear working tub(3) of the rear end of the excavator(4), attaching woven fabric bags(9,9') for ground works attached with an anti-counterflow valve(10) connected with a hose for supplying a waterproofing-cum-subsidence proofing agent intermittently on a location for installing H-beams under the woven fabric plate(7), installing beams(8) on the spot where the woven fabric bags(9,9') are attached at regular intervals, connecting and welding upper ends(8') of the beams by a steel plate(11), then filing up each beam with a bearing plate to form an underground structure bearing wall, installing an anti-counterflow valve(14) connected to an outer hose for injecting a waterproofing-cum subsidence proofing agent to pass through a steel plate(14) and a strut in a space(13) formed among the woven fabric plate(7), the steel plate(11) and woven fabric bags(9,9'), injecting a waterproofing-cum-subsidence proofing agent through anti-counterflow valves(10,14) connected to the outer hose to fill up woven fabric bags(9,9') and the space(13), then hardening to form a ground subsidence-proofing and underground water anti-discharging wall.
