(54) COMPOSITION FOR SOIL SEALING

3

If alkaline agents are used with BMSST with another gelatinizing agent of a known type, then the respective proportions of the two gelatinous reagents in the mixture can be 100-60 wt. h diefi.rov on O-40 weight. h. another reagent.

The following formulas can be used to calculate the relative numbers of komnoneits, the input of ishh into the composition:

reagent weight (S} water volume

silicate volume silicate volume

The compositions are prepared according to known methods of gelatinizing and Pelcolelic silicates. Thus, the average production vari able is to introduce, with stirring, for 1 --- 2 min in an aqueous solution of an alkaline silicate, maintained at normal temperature, a solution or aqueous dispersion of a gelatinizing reagent.

The formulations thus obtained in this case are ready for injection into the soil, 25 intended for sealing or sealing.

In the examples, the following compositions are used, wt.

Methyl methyl acid

Methylglutarate

A1ethyladinate

Water

Ethylsuccinate

Ethylglutarate

Etiladipate

Ethyl alcohol

Water

These mixtures can be obtained (based on any known method.

Example. Prepare a series of gels, just before the use of aqueous sodium silicate solutions with solution dispersed in water. Mn, containing different amounts, the amounts of the gelatinizing reagent. The final compositions are set according to certain ratios of a and b. The main characteristics of the mixtures are then determined.

1. The mixture prepared time is the time required for the surface of the tank, the wave of the gelatinized gel and inclined to the horizons () nta, does not deform.

2. Viscosity V, determined at 20 ° C using Egschrecht's viscometer “Reomat 15.

Example 2. The cylindrical shape (internal diameter 40 mm and length 1500 m.) Is filled with dry sand from a foil neblo.

After the sand has shrunk, a composition prepared from an aqueous solution is sprayed through the base of the form with: - ;; sodium catalate and c-mixture of methyl diethfs ;; and / nl of ethyl diaphragms with different y; tsppsentpani mi.

After filling with the formulation, the mold is cut into cylindrical bars, 80 mm high, which are stored closed at 20 ° C for 7 days. Then the bars of agglomerated sand are pulled out of the mold and subjected to flattening by pressing with a press, the feed rate of which is adjusted to 20 mm / min.
