Title:
REINFORCED SELF-SUPPORTED RETAINING WALL STRUCTURE MAKING USE OF THE ARCHING EFFECT AND A CONSTRUCTION METHOD OF EXCAVATIONS USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/102595
Kind Code:
A2
Abstract:
The present invention is directed to provide a reinforced self-supported retaining wall structure of a new aspect, in which a reinforced soil type self-supported soil mass is formed making use of the arching effect between soil particles and a sheet panel, and the back pressure of soil that is applied to an excavation space is supported by the weight (W) of the self-supported soil mass. To this end, H-piles (10), each housing a soil retaining plate (30) inserted therein and having a sheet panel connection - coupling part formed as one body in the vertical direction on one flange (12) thereof, are arranged regularly in distances B at right angles to the ground; and a sheet panel connection part (22) is first connected - coupled to the sheet panel connection - coupling part (14), followed by a sheet panel (20), provided that the internal friction angle (Φ) of the soil is in the range of 10 to 34 degrees and the relationship between the length L of the continuous sheet panels (20) and the distance B between sheet panels in the presence of an adhesive force (C) within the range of 0.0 to 5.0 (ton/m2) satisfies 0.5 ≤ L/B ≤ 3.0, thereby the arching effect prevents the application of the back pressure of soil to the front soil retaining plate.
