Title:
CONSTRUCTION METHOD OF PRE-STRESSED CAST-IN -PLACE CONCRETE PILE AND STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/126170
Kind Code:
A1
Abstract:
The present invention relates to a construction method of a pre-stressed cast-in-place concrete pile and a structure thereof. More specifically, when inserting a concrete reinforcement bar net for constructing a cast-in-place concrete pile, tension members and protection pipes and the anchorage zones of the tension members in the front end portion of the pile are additionally inserted in advance in the longitudinal direction of the pile. After that, concrete pouring and curing procedures are carried out and then the tension members are tensioned at the top end portion of the pile, so that compressive stress is induced over the entire length of the concrete pile, thereby increasing the tensile strength and the bending strength of a concrete pile structure.
