Composite wall structure of underground outer wall with cip retaining wall

Than by the present invention is fundamentally prevent the displacement occurs in the underground external wall by earth pressure and to absorb the lateral soil pressure generated between the other slab close to the slab of the underground formations does not have point reaction force when hapbyeok the CIP wall and underground outer wall the cost and durability as with about hapbyeok structure of the intake sound insulating and heat insulating property is granted CIP wall and underground outer wall, H-PILE or group to build upon soil decay protection of underground dig around the earth pressure of the basement construction assembly of the reinforcement bar net the after underground teopa due to the phosphorus to the composition of these concrete pile as a kind of small diameter concrete piles are created by filling the concrete is continuously gasiseol structure provided with CIP process to form a primary thermal wall CIP wall, the CIP wall inward and then put into the interior of the underground facility, the outer wall and the outer wall of the basement underground structure which is provided with CIP wall hapbyeok To a plurality of the basement slab horizontally provided so as to partition the layers up and down, and the point the reaction force is inserted between not the CIP wall and underground outer wall to absorb the lateral soil pressure generated between the ground slab and adjacent to other underground slab installed, it characterized in that it further comprises an earth pressure absorber for elastic deformation.
