Title:
METHOD FOR CONSTRUCTING CAST-IN-PLACE CONCRETE PILE
Document Type and Number:
WIPO Patent Application WO/2015/108146
Kind Code:
A1
Abstract:
Provided is a method that is for constructing a cast-in-place concrete pile that increases tip support force, peripheral surface friction, and withdrawal resistance by burying gaps in the concrete pile peripheral surface by placing an expanding concrete to which has been added an expanding material, a gas-releasing agent or aggregate having an expanding effect, or the like. The method for constructing a cast-in-place concrete pile forms a cast-in-place concrete pile (10) by placing concrete in an excavated hole (11) formed underground (A), and is characterized by placing in the excavated hole (11) an expanding concrete (12) to which has been added at least one of expanding material, a gas-releasing agent having an expanding effect, and an aggregate having an expanding effect, and then curing the result to form the cast-in-place concrete pile (10).
