SELF-STANDING TYPE PILE FOR RETAINING WALL USING IN-SITE CONCRETE PILE INCLUDING DOUBLE I-BEAM

摘要

The present invention relates to a self-standing type pile for a retaining wall, using an in-site concrete pile including a double I-beam, capable of performing deep excavation even if an embedded length is short in a section with a narrow property line in a downtown area. A horizontal reinforcing member capable of forming resistance by active earth pressure is connected to an in-site concrete pile including the double I-beam. So, even if the embedded length of the in-site concrete pile including the double I-beam is short and the in-site concrete pile including the double I-beam is not deeply embedded, the self-standing type pile for a retaining wall can improve performance of the deep excavation and constructability. Also, a small inclination reinforcing member and a vertical resistance reinforcing pile connecting the horizontal reinforcing member combined with the in-site concrete are formed. So, an additional bearing force corresponding to the active earth pressure is formed. Therefore, even if the embedded length for forming passive earth pressure is short, the self-standing type pile for a retaining wall can perform the construction of a retaining wall. Moreover, the self-standing type pile for a retaining wall using the in-site concrete pile including the double I-beam can perform deep excavation even if the ground is soft.;COPYRIGHT KIPO 2020
