MAT FOUNDATION CONSTRUCTION METHOD USING HOLLOW PIPES, THE HOLLOW PIPES, AND MAT FOUNDATION FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To implement a foundation hollow slab which contributes to arbitrary design of the thickness of a hollow pressure slab, and to implement hollow pipes which are stackable on each other to reduce the volume thereof, facilitates transportation thereof, is good in workability in the construction field, and high in reliability. SOLUTION: A mat foundation has a hollow portion formed therein, by the plurality of hollow pipes vertically embedded therein. The mat foundation construction method is characterized by forming the hollow portion which is implemented by vertically connecting the pipes together and arranging a floating preventing collar on a lower portion thereof. The hollow pipe and the method of forming the hollow pipe are also provided. COPYRIGHT: (C)2008,JPO&INPIT
