Description

1-1 invention is excluded to the construction industry and can be used to strengthen the walls of soil ekpazhin. There are known methods of forming 11 tr of bonovods in the soil from nlastnchpy.kh concrete mixtures with which the previous | 110 cc-i d 1; Ile wells. 1.1, e, p1 of the acquisition --- an obese (|) oii gas pipe. To do this, a dry mix is taken as a molding material, which is fed into the well with moisture-containing gas. At the same time, injection of a material into its well, its material and re-drilling of a well can be carried out simultaneously, and a non-mentally sandy mixture 1) containing about 30% cement and 70% sand and 5–8% moisture by weight can be taken as a mixture mixture, or a mixture of amoeostoniteite, contains about 30% of the nonmentum and about 70% i of the compound and 25 moisture based on the weight of the mixture. FIG. Figure 1 shows a well before the pipeline formation section, longitudinal section: fng. 2 - well in the pro5 10 15 20 LO process, shaped pipe, longitudinal section. The inlet 1) T -; the hole formed by the well 1 is tightly closed with the sleeve 2 1; the dry mixture 3 is pressed into it by the gas with dry gas 3 in June 1, its n is the filler. The lipeMH is filled with the inlet of the formed well and is closed with an operating 4, 1, and the channels for discharging the compressed gas. In transiostration, the dry mixture 3 is wetted, and the amount of moisture supplied to the compressed gas depends on the mixture and moisture content of the soil. Then, but the well is filled with a self-propelled pneumatic device 5, which, with its housing n.1otn art.1, the mixture of and forms a pipeline 6 from it, a 6. At the same time, the speed of advancement of the device 5 along the well should not resemble the speed of filling it with the mixture 3. For pipelines with a length of 10-15 Л1, manufactured in soils, are not suitable for shorter loads, as a result: sieved river sand. Сofruii mixes about M% of cement and about 7 () m of sand.

When forming pipelines of a length of 11 U, made under the railways of the Asia-Pacific Road, it is advisable to use & as-nest as nest. The composition of the mixture is about 30% nement and about 70; o asbestos.

The total amount of moisture that enters the dry mix 3 at its own is not enough to reach 5–8% by weight of non-fine sand, 12–15% by weight of asbestos-rich mixtures.

Formula and Testing 1. A method of forming pipelines in the soil by punching a well, filling the well with molding material and re-drilling the well, so that in order to ensure the formation of the pipeline, a dry mixture is taken as the molding material which is injected into the well by the state containing gas. 2, The method of π. 1, characterized in that the injection into the well is The 5th material and re-penetration of the well are performed simultaneously. 3. The method according to PP. 1 and 2, characterized in that as the dry mixture takes 11, emo and t 11 about - about 11 hours. 10 4. The method of pi. 1 and 2, according to the fact that asbestos-cement C M C C b is taken as a dry mixture. 5. The way io and. 3, on the basis of the following: ι th with that. that the cement-sand mixture contains g 15 about 30% cement and about 70% sand. 6. The method according to p. 4, about hectare and with the fact that the asbestos-cement mixture contains about 30% cement and about 70% asbestos. 7.
