THE EARTH RETAINING WALL CONSTRUCTION METHOD WHICH USES H-PILE WHERE ATTACHES THE PARAPIN AND H-PILE DRAWING METHOD

摘要

PURPOSE: A construction method of a temporary earth retaining wall using an H-pile coated with paraffin and a drawing method of an H-pile are provided to easily draw an H-pile out of the ground by reducing frictional force. CONSTITUTION: A construction method of a temporary earth retaining wall using an H-pile coated with paraffin is as follows. The ground is bored along a boundary line where an underground structure is to be installed. An H-pile body, which is to be inserted into the borehole, is coated with paraffin. The H-pile and a reinforcement cage are inserted into the borehole. Soil cement or concrete is placed in the borehole depending on the kind of a temporary earth retaining wall(100) and is cured. After the underground structure is formed, the H-pile is drawn out of the borehole.
