SU40393A1 - Conjugation of slag cushion with natural soil - Google Patents

Description

Slag cushion mating with natural soil along the axis of the path is made with steep slopes, by applying sand located between the slag pillow and natural soil in such a way that a triangle facing downwards with a base equal to the length of the outlet and sides corresponding to the length of the slopes of the pillow and natural soil.

In FIG. 1 shows a pond formation pattern; FIG. 2 — Slag bedding with normal bonding; and FIG. 3 - slag cushion of the proposed conjugation.

With the long tails of the usual conjugation (fig. 2) of the slag bed with the natural ground, over a period of time a very thin slag band is obtained, which practically cannot produce a corresponding effect.

The calculation of such conjugation, according to the theoretical calculations of the applicant, can be made as follows: if / - / designate the axis of the path to winter swelling (Fig. L): II - // - the axis of the path after swelling, on which a is an unevenly bulging part (hump), on the sides from which evenly distending parts are located, and if i is a slope, which in time is given a smooth retraction from the hump a (its height is AZ), then when it is removed, p (318)

house in the tonnage abyss height Aj. To prevent this from happening and to make the transition from a non-intumescent part of the path (as a result of laying a slag cushion with a thickness of //) to a uniformly intumescent, be sufficiently smooth, it is necessary that

/ -.

For example, with L 40 mm „i 0,002

, 0.04 mpt

we receive / c 20 m.

If the thickness of the pillow H is 0.4 m, then the slope (conjugation) of the outlet will be

OL 20

 0.02.

In this case, over 5 m from the end of the mate to the middle of the pillow, its thickness will increase from zero to 10 cm, i.e., its thickness in this area will be negligible.

The present invention (FIG. 3) is intended, with the same length / removal, to obtain a greater slope of the slag cushion A. For this, the conjugation of the slag cushion A over time does not descend from Ci and Cj to Sj and 2 and

next stretch, i.e. from

and V., to L and AZ, the sand backfill D juxtaposition comes out. Thus, the sand backfill D in section along the axis of the path is obtained in the form of triangles AiOiBi and with vertices BI and B2, facing downwards / JjCi and equal to the length / tap and sides C | Si and, AiB and., corresponding to the length of the slopes of the pillow 4 and the natural soil E.

In such a device, according to the inventor, when going from GI and Cz to 5 and B., the depth of frost penetration to its normal value increases, with gradual entry into the frost penetration sphere of the intruding soil located under the slag pad within . the soil, in the opinion of the applicant, gives a uniform swelling / Zi when it freezes from the soil surface to the full value of the freezing. From and, and Cj begins to enter the sphere of freezing of the soil between the lines and throughout (similarly, from So to C -) -.

The process of gradual entry into the freezing zone of the intumescent soil, thus, occurs completely continuously and pa6ioTa of the mating of the slag pad is greatly improved.

The subject matter of the invention.

Slag cushion mating with natural soil along the axis of the path during the elimination of soil depths, characterized in that, in order to preserve the gradual entry of intumescent soil into the freezing zone with increasing slope steepness, sand D is applied between the slag cushion A and natural - ground E in such a way that, in a section along the axis of the path, there is formed a triangle facing downwards with a base equal to the length / retraction and sides corresponding to the length of the slopes of the pillow A and the natural group that E (FIG. 3).
