Title:
COMPOSITION FOR FOUNDATION DIGGING/POURING MATERIAL, FOUNDATION DIGGING/POURING MATERIAL, AND OPERATION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2015063669
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a composition for foundation digging/pouring material, in an original position mixing/stirring process and a soil pressure shield process, imparting a function of enabling a safe and smooth operation by mixing with digging earth upon digging, and the original position mixing/stirring process and the soil pressure shield process increasing the durability of bubbles to de-bubbling when the composition for the foundation digging/pouring material is bubbled and using the same as the foundation digging/pouring material.SOLUTION: Provided is a composition for a foundation digging/pouring material mixed with water, a dispersion liquid of a high water absorbing polymer swelled by being absorbed with the water and an air bubble agent. The high water absorbing polymer is at least one kind selected from starch series, cellulose series and synthetic polymer series and has a cross-linking structure where the water is not released by pressurization, and the funnel viscosity of the composition is 19 to 60 seconds.
