METHOD TO CONSTRUCT SOIL RETAINING STRUCTURE BY USING CONCRETE PRECAST PILE AND CAST-IN-PLACE PILE

摘要

A soil retaining structure of the present invention includes: a concrete pile wall (200) formed by consecutively inserting a plurality of hollow concrete precast piles (220), installed in a vertical direction of the ground (100), into the upper part of a bedrock layer (120); a main pile (210) installed more deeply than the precast piles (220), and inserted into the bedrock layer (120) in a section between the concrete pile wall (200) and another concrete pile wall (200), adjacent to the first one; a combination groove (213) formed on the inner surface of the main pile (210); a combination part (500) installed in the combination groove (213); and a wale (400) combined with the combination part (500). The pile wall (precast piles and cast-in-place piles arranged in a line) is formed by using the concrete precast pile, inserted into the upper surface of the bedrock layer, and the cast-in-place pile, inserted into the bedrock layer, and the combination part, combined with the wale, is installed in a side part of the cast-in-place pile including an H-shaped steel pile. As such, a substantial soil retaining structure is able to be installed. Moreover, the present invention is capable of improving the resistance of the soil retaining structure by additionally installing an earth anchor in the retaining structure depending on rear earth pressure.;COPYRIGHT KIPO 2017
