また酸・アルカリの中和理論からしてこの範囲にｐＨを
調整することは極めて困難である。By the way, in the silica sol grout, maintaining the gelation time within the range of 3 minutes to 300 minutes is to adjust the pH of the sol within the range of 3-5. However, due to the nature of silica sol grout,
Also, it is extremely difficult to adjust the pH within this range based on the theory of acid / alkali neutralization.

間は定まってくる。It has already been found that the gelation of silica sol in the acidic region depends on the value of [H + ] / [SiO 2 ] n (hereinafter referred to as X value) of the sol. That is, the gelation time is, of course, largely dependent on [H + ] of silica sol, but the composition of water glass (SiO 2 , N 2
a 2 O) and the concentration, and the gelation time is substantially determined by the X value.

ようにし、本発明を完成するに至った。The present inventor has found that when the silica sol in the acidic region is injected into the soil, the gelation time of the silica sol itself is generally remarkably shortened in the soil, and further, the silica sol itself and various silica sols are shortened. From the gelation time when it is injected into a wide range of soils from acidic to basic, the relationship between them is clarified, the base of the present invention is achieved, and a gelation accelerator is added to The present invention was completed by adjusting the value and making it applicable to grout with a wide range of gelation times.

When silica sol in the acidic region consisting of an acidic reaction agent and water glass is mixed with soils having various pH values shown in Table 1, the relationship between the X value and the gelation time of the silica sol used is approximately:
It has been found that it takes an aspect as shown in FIG. (Measurement temperature: about 20 ℃).

When mixed with the soil shown in 1 above, the gelation time was significantly shortened by the pH of the soil, and the degree of shortening was particularly large in alkaline soil.

けではない。As shown in Table 1, the pH of soil is almost in the range of about 5 to 9.5 except for special exceptions, and even at the same pH, gelation is not always caused by the difference in water content and components in the soil. Time is not only dependent on soil pH.

推察できた。In any case, as shown in FIG.
The gelation time of silica sol in soil was significantly shortened, and the straight line B (for pH ≈ 5 soil) and the straight line C (p
It can be inferred that it will be almost settled during the time of H ≒ 9.5 soil).

In order to reach 300 minutes, it is sufficient to inject the silica sol mixed so as to have the X value corresponding to the shaded portion between the straight lines B and C in FIG. 1 into the soil of the injection target ground.

It is also possible to apply a silica sol having an appropriate X value consisting of an acidic reactant and water glass as solution A, and add a gelation accelerator as solution B to this solution to apply it to a wide range of grouts from instantaneous setting.

たる広範囲のグラウトへの適用も可能となる。Since various inorganic and organic substances are dissolved or mixed in the soil, and the silica sol in the acidic region has a low viscosity, it rapidly penetrates into the soil and reacts with these soil components, mainly [[ H + ], which leads to a decrease in the X value and shortens the gelation time. The degree of shortening depends of course on the physical properties of the soil, especially the pH and the X value of the silica sol. Further, the X value can be adjusted by a gelling accelerator, and it can be applied to a wide range of grouts from instantaneous setting to long time.
