P-CIP Prestressed Cast in Place Concrete Pile Assembly for Retaining Wall And Method for Constructing the Same

摘要

The present invention relates to a pile assembly and its construction method that implements the P-CIP (Prestressed Cast in Place concrete pile) retaining wall construction method by applying a tensile force upward after reinforcing reinforcement and pouring concrete without inserting an H pile or a specific type of pile. In relation to the present invention, a pile assembly for a P-CIP retaining wall according to the present invention comprises: a lower plate installed on a bottom surface of a hole drilled in the ground; An upper plate installed at the top of the hole drilled in the ground; A plurality of reinforcing wires having a lower end fixed to the lower plate and an upper end fixed to the upper plate; A plurality of tension wires having a lower end fixed to the lower plate and installed so that an upper end penetrates the upper plate; A plurality of coverings surrounding the outside of each of the plurality of tension wires; Concrete poured into the hole and cured; And, after the concrete is cured, a tensile support means for fixing and supporting the upper plate in a state in which a tensile force is applied upward to the tensile wire rod.
