Title:
FILLING MATERIAL
Document Type and Number:
Japanese Patent JP2019104805
Kind Code:
A
Abstract:
To provide a filling material capable of completely filling a duct line with sand or the like without pump force feed with using flowability to move coarse particle material and coarse aggregate long distance.SOLUTION: A constituting material consists of a separation resistant material, a coarse particle material, water and a fine air bubble, in which the added water is 1.9 to 19.0 wt.% based on weight of the separation resistant material, specific gravity containing air after milling and mixing is 0.7 to 2.1, material is not separated in water, having self leveling property for enlarging a filling area by flowing in a cavity by self weight without relaying on pressure, and exhibiting water permeability with water permeability coefficient of 1.0×10cm/sec after filling. Further a separation promoter is preferably added after supplying to a cavity to be filled (for example a subsurface drain pipe).SELECTED DRAWING: Figure 1
