To propose a water-stop wall that is simple and easy to construct and can be easily removed when no longer needed.

る必要かあり、一層手間がかかり、コスト＾となった。Excavating the ground to a depth below the groundwater level to form a slope,
When constructing underground structures, it was necessary to prevent underground water from leaking, and the method of providing a water stop *V + stage was often adopted. Jubei's water stop is formed by excavating the ground and pouring concrete, or by adding sheet piles, etc., so construction is time-consuming, and when it is no longer needed, it is difficult to remove it. It took a lot of effort. In addition, if the ground has high permeability (for example, permeability coefficient kW > 103/m) and there is a large supply of groundwater, it may be necessary to use chemical injection, which is more time-consuming and costly.

要も生じ、運転、管理が繁雑になる場合もあった。Moreover, if you try to construct a water cutoff wall by excavating the ground or driving sheet piles, the vibrations may cause the excavation slope to collapse, and the water cutoff wall
For example, it became necessary to change the water at a well point, etc., making operation and management complicated.

１成せしめることかできる。When these resin powders are injected or mixed into the ground, they absorb water in the ground and swell and gel, filling the soil voids in the ground and creating water-stopping ground. Therefore, if this resin powder is distributed and mixed into the ground in a wall-like manner, it is possible to form one water stop Il.

When it comes into contact with SS ice water solution, it loses its ability to swell and form a gel. Therefore, after functioning as a water stopper for the required period, when it is no longer needed, the swollen gelled resin powder is returned to its original powder shape by press-injecting the % delyzed aqueous solution to improve water permeability.

。The resin powder used is usually one having a particle size of approximately α05-toss. If it is too large, it will be difficult to uniformly fill the narrow voids in the ground, and if it is mixed with a non-aqueous liquid, the slurry will become unstable, and the swelling and gelation will be slow, which is undesirable.

定される。It can be selected from ethylene glycol, glycerin, etc., and can be used alone or as a mixture. When water-soluble or hydrophilic liquids such as alcohols, ethylene glycol, and glycerin are used, when they are injected into the ground, they are quickly replaced with groundwater and are effective in hastening the swelling and gelation of resin powder. The composition of the non-aqueous liquid is determined by taking into account the iron quality, the ground, the water stop level, the working conditions, and v':4.
