Abstract

PURPOSE:An instant soil stabilizer having high permeability and hardening strength, small influence of temperature during gelatinization, and no fear of pollution, comprising sodium silicate as a main agent and sodium bicarbonate as a hardening agent. CONSTITUTION:For example, (A) water is added to 375kg sodium silicate to give 500l solution, and (B) water is added to 40-60kg sodium bicarbonate to give 500l solution. 1,000l of total amounts of the coponents A and B are used as an impregnation amount based on 1m<3> soil, the two solutions in separated state are poured into a double boring pipe, the two solutions are mixed at the tip of spray end of the boring pipe, and impregnated into ground, the solutions are penetrated into the ground, gelatinized in short time, and hardened, so that water at oozing part is stopped, leakage of water is prevented, and ground is reinforced.

To explain the embodiment of the present invention shown in the drawings: Sodium silicate (NCLIO-nsioz) 3 7 5 K
Add water to f to make 500 l (liquid A), make it heavy (NαH
Water was added to 9 (10-16% for 375 Ky of sodium silicate) to 40-60 (COa, sodium hydrogen carbonate) to make 500/(Liquid B), totaling 1000! Quantity to soil type 1
Use it as the injection amount per head, and add the above 2 to the double poling tube.
When the liquid is injected in a separated state and the two liquids are mixed at the spout at the tip of the polling pipe and injected into the ground, both liquids seep into the ground, gel and solidify in a short time, and the seepage area It is possible to stop water, prevent water leakage, and strengthen the ground in the same area. The above-mentioned sodium silicate is a pale gray or gray semi-viscous liquid with a specific gravity of 1.55, and the heavy liquid is a white powder with a specific gravity of 2.2.

Therefore, pressure relief such as shield construction method and caisson construction method is prevented.
Increasing the bearing capacity of the foundation ground for various structures, preventing uneven settlement, preventing water leakage when excavating tunnels and shafts, ground stabilization, reinforcing defects such as piles and preventing water leakage, ground reinforcement of adjacent structures during earthwork excavation, and during excavation. As mentioned above, the soil stabilizer can be used for quick sand, piping prevention improvement, embankment, seawall prevention, mountain retaining in cutting work, etc., to stabilize and strengthen the ground, form an impermeable layer and stop water.

As described above, the present invention is a soil stabilizer made of sodium silicate as a main ingredient and heavy soybean as a hardening agent, so it is easy to adjust the chemical solution, and it is suitable for on-site adjustment without requiring delicate formulation management. Water quality monitoring only requires a PR check, and the curing ingredients do not contain fluorine compounds, so there is no need to worry about environmental pollution from organic matter, and a stable gel time can be obtained.Also, it has excellent solubility and uses acidic substances. Because it is not used, there is no corrosion of injection machines, etc., and the gelation time is fast, which improves the effectiveness of the so-called grout packer, which prevents the escape of gelled substances in multi-layered ground and improves the specified area, and quickly forms an impermeable layer. It is something that can be done.
