Abstract

The invention relates to construction. The aim of the invention is to reduce the labor intensity of the work. In shells installed in a row, a slit 7 is cut through the backfill material 6 along the longitudinal axis. Fill the slit 7 with an anti-filtration mixture to a waterproof layer 5. In some cases, after a partial backfill, a horizontal waterproofing lock is made in the lower part of the shell 1 . In this case, the filling is continued after cutting the slit 7 and filling it with an anti-filtration mixture. The arrangement of the slit 7 is carried out, for example, by vibrating immersion and extraction of the inverter elements with simultaneous feeding of the impervious mixture. The implementation of the impervious curtain over the entire height of the backfill material overlaps the upper path of the water before entering the pit. I zp f-ly, 3 ill. se / 4- /) (L

tees, but also penetrates the surrounding soil ,. V.TOM number and on the site, which is bounded above by the ends of the shells. In addition, the use of vibration technology due to the dynamic effect on the soil 5 provides for the destruction of the soil septum in this area and the connection of the slotted slot with a cavity filled with the anti-filtration mixture in the adjacent shell.

Dipping inventory elements before they are buried in the water column eliminates or drastically reduces water filtration from the bottom of the jumper, and the implementation of an impervious curtain over the entire height of the backfill material blocks the upper path for the water to fall.

The invention relates to the construction and can be used in the construction of enclosing jumpers ditches on permeable soils of the water area.

The aim of the invention is to reduce the labor intensity of the work.

FIG. Figure 1 shows the barrier, plan; in fig. 2 is a cross section of the shell after filling the bulk material, cutting the slot and filling it with an anti-seepage mixture (section A-A-YoYa in Fig. 1); in fig. 3 - the same, but with the formation of a horizontal lock of antifiltration material.

FIG. 1-3 presents: cylindrical 1 and deformed to the center .. „,

along the vertical axis of the shell 2, which is enclosed in the excavation pit, rye are installed along the axis 3 of the web. In a number of cases, for example, when the height

The soil of the base includes water-permeable shells exceeding its diameter, economical 4 and waterproof 5 layers. The strip 6 material is placed in the lower part of the shell of the shells of the backfill horizontal horizontal insulation block, filled with an impervious jn lock 8. For this, after installing the mixture, the slot 7 and the horizontal lock 8 of the shell into place, its cavity partially from the anti-seepage material is filled with backfill material. The height of the method is carried out as follows: the test is determined on the basis of the condition that the shell is stabilized during the period

Regular cylindrical or deforming works. Then, over the entire area of the shell of the tilted-axis shell 2, the impervious material is placed over the entire surface of the shell along the vertical axis 25, the material is installed in place along the Z axis. The gaps are cut through the jumper axis with the master lintel. The cavity is filled with the filling of the anti-filtering core with filling material 6, for example with a mixture, and after performing these operations with sand, in order to ensure the stability of the constructions, the cavity of the aditine bridge is filled and the building material is filled into the design shell within , marks. which eliminates their deformation from the action of water.

Then, in the cavity of the shell along the lintel axis, through the backfill material 6 and the water, ... permeable base layer 4, the lintels on permeable soils cut the slit 7 and fill it with the anti-filter area, which includes installation in a variety mixture.

If the base of the enclosing bridge Formula of the invention 1. The method of construction of the enclosing

thin-walled shells and backfilling of their cavities with loose material, characterized in that, in order to reduce the labor intensity of permeable and clay soils, 40 works, in the waterway installed on the water area, the slit 7 is cut to the water seal, along the barrier enclosing the jumper through the backfill material and permeable soil cut a slit and fill it with an anti-filtration mixture by vibrating immersion and removing hollow

filtering mix is carried out, 45 inventory elements with simultaneous, for example, by vibrating immersion of an impervious mixture mixture, with

This slot is cut before the inventory of elements is immersed in the waterproof layer. 2. A method according to claim 1, characterized in that in the process of filling the shell cavity with a bulk material in its lower part a horizontal lock is formed of

Cutting the slit 7 and filling it out with the extraction of hollow inventory elements with simultaneous supply of the impervious mixture.

Consistently plunging and removing inventory elements along the axis of the lintel and feeding the mixture over them, a continuous impervious curtain is obtained, since the mixture pumped with an overpressure not only fills the half-filtering material that is formed when the element is removed, but after filling the slot and filling it with an impervious filtrate mixture.

In addition, the use of vibration technology due to the dynamic effect on the soil provides for the destruction of the soil septum in this area and the connection of the slotted slot with a cavity filled with the anti-filtration mixture in the adjacent shell.

Dipping inventory elements before they are buried in the water column eliminates or drastically reduces water filtration from the bottom of the jumper, and the implementation of an impervious curtain over the entire height of the backfill material blocks the upper path for the water to fall.
