Abstract
PURPOSE: To break concrete in a safe and easy manner by employing the concrete crushing body containing a substance having hygroscopic and expanding properties in breaking extra-banking after the driving of a concrete foundation pile.
CONSTITUTION: The concrete crushing body shaped like a slender bottle containing a substance having hygroscopic and expanding properties provided with a cover at the upper end thereof and a sand-packed section at the lower end thereof is inserted into a mud water 25 in a pile hole 24 incontact with the upper end of a foundation pile 22. A body for forming a free surface 27 is arranged surrounding a frame 26 roughly contacting the circumference of an extra-banking 23, into which then, concrete is cast. After solidification of the concrete, the cover on the crushing body 1 is removed and a mud water 25 is poured thereinto. After a given time elaspes, a hygroscopic and expanding substance is expanded causing a crack in the extra-banking 23. As a result of dislodging and weakening, the extra-banking has been already broken when the soil was excavated up to the depth thereof because of its underground structure.
