GROUND INJECTION METHOD AND INJECTION MATERIAL
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
【課題】不均質な地盤において、地盤の止水性の向上、強度増大および液状化防止等の地盤改良を広範囲にかつ逸脱することなく確実な浸透固結を可能にするためのおよび地盤注入工法を提供する。【解決手段】非アルカリ性シリカグラウトを用いて注入孔間隔、注入ステージ、注入量、注入速度、注入時間に対応して、注入範囲への逸脱を低減し、広範囲の土粒子間浸透を行って、所定量の注入に対して所定の固結体を形成するための注入液の処方を設定するとともに所定の注入設計を行うと共に、所定の注入が行われていることを可視化することにより、施工管理を確実にし、かつインターネットによる施工管理システムや自動注入も可能にしたものである。これによって不均質な地盤でも一次注入、二次注入の複合注入が可能になり、大きな固結径の形成と所定の範囲外への逸脱を防ぎ、経済的で確実な地盤改良が可能になる。【選択図】図２７
