JPS58191811A - Prevention of leak of water from ground - Google Patents

Abstract

PURPOSE:To exactly prevent the leakage of water from the ground by a method in which a powdery granular resin capable of being swelled and gelled by the absorption of water is charged, together with a nonaqueous liquid, into the ground in such a way that moisture in the ground is absorbed by the powdery granule resin and the resin is swelled and gelled. CONSTITUTION:A resin (e.g., starch-acrylonitrile or starch-methacrylate graft copolymer, partial hydrolysates of unsaturated carboxylic acid copolymers of polyacrylonitrile or vinylester-ethylene series, etc.) capable of being swelled and gelled by absorption of water, together with a nonaqueous liquid (e.g., oils, alcohols, ethylene glycol, etc.), is slurried by mixing and the injected into the grounds A and B through a bore hole 4. The powdery granular resin absorbs the ground water and is swelled and gelled to form a cut-off layer.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing water leakage from ground, and more specifically to a method for preventing water leakage from excavated ground, etc. in μton Furue@VC. Purpose 1 is to use a water leakage prevention method that is easy to operate and ensures that young rice is water-proof.

Conventionally, in order to prevent underground water from leaking from the ground, for example, in tunnel equipment, a method of injecting 11 L of mortar liquid into the ground and gelling or hardening it was used. However, in places where there is a large amount of water, it may be diluted before gelatinization and the effect may not be achieved, or it may be difficult to gel the gelation time, or it may gel before it penetrates into various locations. As a result, water leakage could not be prevented with certainty. In addition, when excavating the ground below the groundwater level, it is necessary to change the water using a quellboint force to prevent water leakage. In this case, sheet pile and injection of prefectural liquid are also recommended. Therefore, I would like to give a big thumbs up to the work to prevent water leakage, and the certainty is definitely WbI! 6 It wasn't ugly.

This invention was made in view of the problems such as the above ml, and its % value is based on vM oil powder grains [pressed into the ground together with non-aqueous materials], which have the property of absorbing water and forming into clay. And this resin powder '8. [Absorbing moisture in the ground &
This is a method to prevent water leakage by gelling the Chole l# cavity.

This prevention method improves workability by mixing resin powder and granules that absorb water and swell (hereinafter referred to as 1IIf fat powder and granules) into a non-aqueous water liquid to form a slurry and deposit iCC in the ground. (Resin powder and granules penetrate well into the ground, and water is sown into the ground and some parts ((-included!ll included) are included in the ground barrier and ground barrier.In addition, it is injected together with non-aqueous enemy formations. -J' for the sake of shouting m powder grains 1, press-in, and during agitation, the amount of acupuncture of underground water Ku; is small, and in order to maintain a fine powder shape, the penetration into l1lN + shrine 1 gong is controlled by ml. Not at all.

Ju! The soybean fat powder that penetrated the koji's destroyed position expands like a non-aqueous enemy's base that was injected together with it, and is resistant to ground water and absorbs it, causing a -℃ shock. The soil becomes regulated and an impermeable layer is formed in the ground. %, Tomozaki oil powder grains I + 1 water can easily pass through the permeable ground VC-dog p (it can be penetrated, so the rate of increase is 1 water to the size of a plow) tP) i can be stopped.

As for the penguin used in this Koushi, which absorbs water and turns into a powerful force, it does not understand water, but instead absorbs water and slowly changes its shape from the beginning to the end. -Ed%lIl powder-1 Chrylonitrile or al! Powder to methacrylate graft compound, polyacrylonitrile f vinylnisder-ethylene thread unsaturated carbon relative compound f+D partially hydrolyzed Ha, sulfonated styrene-based polymer introduced by Yasushi Sasui, polyethylene oxide, polyvinyl alcohol, Vinylpyrrolidone, polyacrylic powder, polyacrylamide, carboxymethyl cellulose,

When some ceramics (such as calcium chloride) come into contact with an electrolyte water bath solution, they lose their ability to form a gel. Therefore, if it becomes necessary to prevent the M-seki side water, and if it becomes a small wise, these electric % Revert to , and add a note to water@

At 1st level, it is affected by the resistance and fire of the non-aqueous enemy.

Hereinafter, I will give a detailed explanation of how this splint method is applied.

Example 1: Preventing water leakage due to ton failure work◆.

The composition of the powder offering on the side of the garden: non-water $ enemy camp (glycerin) 2 mm of alcohol was stirred into a shape of 7 tons and 4 tons.

Press-in failure: In Figure 1, Bolink Kokurasha was sent to Asahi-Yen A and B points, and 60 tons of slurry was produced in Figure 1. The results are shown in Table 1.

(Table 1) In this example, the powdered fat powder and the non-aqueous IfIL were used.

Then, a bowl of water-based slurry of granules with the same composition as in Example 1 was placed in the 9th position of the alcove. Then inject your friend.

Do not change the water and excavate / l WJ should not be removed and maintained.
In addition, a lot of effort is put into salt, and there is a lot of underground water supply, and the permeability of ground #1 is high, and sheet piles and chemical solutions are a must-have companion. However, with this method, it was easy to create rows, the water was stopped instantly, and the slope did not collapse.

Real Jmtl15: Hydraulic water stop - I! As shown in Figure 6, a water stop layer was constructed using a four-line powder and granular material with the same composition as in IjJ 1, and the auger 12 was used in the local bank 11i to build a water stop layer. The two powder particles that were absorbed into the ground water and turned into shadow-toned particles are mutually concentrated and continuous.
Is it possible to form tc, m easy water stop-13? friend.

Conventionally, a water stop was installed ((n is the ground was excavated and concrete was constructed) and four rows were installed (9, 7-) by digging the pile joint. It is extremely easy to install the water stop in the dog seat c. You can recover Sansuichu. Jumei's water stop-1i
It would require a great deal of effort to remove it.

To prevent this, I dredged most of my friends.
