TEMPORARY SOIL RETAINING WALL STRUCTURE FOR WATER SUPPLY AND DRAINAGE WORKS DEEP UNDERGROUND

摘要

The present invention suggests a temporary soil retaining wall structure for deep depth installed on both inner sides of an excavation part (2) for preventing collapse of the side wall of the excavation part (2) formed by foundation work on the ground (1), The temporary soil retaining wall structure is characterized by comprising: a pair of piles (200); a gap maintenance member (201) installed between the piles (200); a guide member (100) installed to guide the vertical movement of the piles (200) and the gap maintenance member (201); a top soil retaining plate (110) coupled to the back side of the guide member (100); a bottom soil retaining plate (210) installed on the bottom of the top soil retaining plate (110). Thereby, the temporary soil retaining wall structure has advantages of convenience and safety in construction and increased recyclability of material.
