Title:
地盤注入工法並びに注入材
Document Type and Number:
Japanese Patent JP6995328
Kind Code:
B2
Abstract:
To provide a ground injection method for enabling solid penetration and consolidation over a wide area without deviation for ground improvement in the heterogeneous ground such as improvement of water stoppage of the ground, increase in strength, and prevention of liquefaction.SOLUTION: A construction management is ensured, and a construction management system and automatic injection via the Internet are also made possible by: using non-alkali silica grout to reduce the deviation to the injection range according to the injection hole interval, injection stage, injection amount, injection speed, and injection time; performing a wide range of soil particle infiltration; setting a prescription of an injection solution for forming a predetermined solidified body for a predetermined amount of injection; performing a predetermined injection design; and visualizing that a predetermined injection is being performed. As a result, a composite injection of a primary injection and a secondary injection can be performed even on the inhomogeneous ground, the formation of a large consolidation diameter and a deviation from a predetermined range can be prevented, and the ground can be economically and reliably improved.SELECTED DRAWING: Figure 27
