An underground retaining wall method-cum-underground structure construction method is provided to simplify the construction work of the basement by performing underground pit excavation work and underground structure construction work simultaneously, and to reduce the cost of construction by shortening a period of construction. An underground retaining wall method-cum-underground structure construction method comprises the steps of constructing an underground structure(100) above the ground, excavating the lower part of the underground structure, supporting the underground structure to an excavation plane and installing a jack support(104) to control the height of the underground structure, descending the underground structure with the jack support and settling down on the excavation surface, and repeating above mentioned steps in orders and descending the underground structure to the required location, and then removing the jack support. |
