The invention relates to road construction, in particular to strengthen the slope of the subgrade of roads, dams and similar constructions, which require filtering of surface water and protection from opolzaniya soil slope.

Known filtering mattress [4] to strengthen the banks of navigable canals, rivers and reservoirs, which prior to installation on the slope, rolled-up and secured on the slope of the pins. A disadvantage of this device strengthening Odesa of several layers of synthetic fabric, for example, from fishing nets.

A known design of strengthening of slopes of embankments [3], in which in order to reduce consumption used geotextile material the coating is performed with periodic cuts, however, in this case a large surface slope remains unprotected from the weather and possible sliding of soil with grass for the locations of the cutouts.

A device of the strengthening of slopes [2], made in the form of bonded between a curved ridges, forming a free space for filling with soil. This design requires a minimum amount of material for its manufacture, holds the soil and water filters, however, difficult to manufacture due to the large number of fasteners and not high-tech during storage and transportation, so as not rolled into a roll.

The closest analogue of essential features is the design of the strengthening of slopes [1] - prototype, including flat products with parallel regularly spaced overlapping along its length slits, the spaces between which are selected from the condition of education is space between the curved ParameterName vegetable soil. The disadvantage of the prototype is the poor reliability due to the pouring of the ground through the upper edges of the plates, on which are formed longitudinal folds and banners, and also because of the gaps flat products due to uneven loading bridges or under the action of tensile forces when laying on a slope or under the influence uploaded into the free space between the jumpers ground, or after precipitation as the result of opolzaniya ground.

To address these shortcomings and improve the reliability of the proposed design of the strengthening of slopes, in which the jumper from a flat material, in contrast to prototype a self-made thanks to the extensions of the slots at the ends. Under the influence of the loaded soil in the free space between the curved lintels each jumper has the ability to samoustraniajutsia, for example, as a rectangular canopy by means of straps under the influence of air, i.e. additionally to bend and turn so that the soil is not poured over the top edge of the jumpers and uniformly loaded material jumper.

The purpose of the invention is the increase nade is diversified slots "A", have the extensions "B" at the ends, used in the construction of fortifications slopes of Fig. 2 - flat product with a transverse perforation, in a rolled form; Fig. 3 - flat product with a longitudinal perforation, in a rolled form; Fig. 4 - copy geomoto obtained by extruding flat items on the slope or the slope.

The design of the strengthening of slopes is arranged as follows. Geosynthetic material is perforated as shown in Fig. 1, and through the slots have their ends extend and are arranged in parallel rows so that along its length, the slots of adjacent rows overlap in length to each other, forming a jumper geosynthetic material vigibase from the plane of the geosynthetic material in the tensile force vector which is perpendicular to the parallel rows of slits.

The design of the strengthening of the slopes of the flat product is made in the form of paintings of the geosynthetic material.

Geosynthetic material for easy transportation and installation on the slope can be rolled up into a roll, the direction of the slits can be made across the length of the flat material on the roll, as pok is EfE geosynthetic material, subjected to the stretching force perpendicular to the direction of the slots, takes the form of geomoto 1, as shown in Fig. 4. In the upper part of the slope 2 geocity 1 are fastened by wedges 3 for initial fixation and prevent opolzaniya of geomoto down the slope. Formed by the space between the ridges flat geosynthetic material is filled in vegetative soil, where the roots of vegetation in addition fix the soil in Geostar and prevent it from sliding and erosion of surface waters.

The reliability of the design of the strengthening of slopes, made in the form of geomoto of geosynthetic material extensions of the slots, substantially higher than in similar without expansion slots, as in the proposed design each jumper has great mobility and can individually, therefore better able to adapt to the effects of soil and better protects it from erosion surface waters.

As a variant may be constructed strengthening of slopes in which the free space between the ridges flat products filled with concrete. When this expansion at the ends of the slots function as technological overuse.

The reliability of the design of the strengthening of slopes, made in the form of concrete slabs separated geosynthetic material and bonded monolithic concrete lintels, significantly higher than in normal concrete slabs on the slope, as provided by the joint work of the concrete slabs between themselves and together with geobotany of geosynthetic material. This saves bandwidth for filtration of surface water through the gaps between the concrete slabs, filled permeable geosynthetic material.

The design of the strengthening of the slopes is as follows. Geocity, being laid on a slope, filled with vegetable soil and overgrown with vegetation, forming a twisted roots and sealed with a ground slope sod layer, which is well water filters and protects the slope from erosion and opolzaniya ground.

FIELD: building, particularly hydraulic structure reinforcement.

SUBSTANCE: method is performed in two-stages. The first stage involves forming vertical elongated flat ground massifs secured by hardening material. Massifs are created in crest embankment area and in upper area of embankment slope so that massifs are spaced minimal available distance from crest and pass through embankment body, including land-sliding upper embankment slope area. Massifs are anchored in mineral bottom by lower edges thereof and are arranged at least in three rows and there are at least three massifs in each row. Method for massifs forming involves driving double-slotted injectors directly in embankment ground or in wells formed in embankment and having plugged wellhead; orienting injector slots perpendicular to hydraulic pressure head vector direction in embankment area to be reinforced; injecting hardening material under increased pressure across horizons from top to bottom or in reverse direction, wherein injection is initially performed under 5-15 atm pressure and at minimal rate in each second injector of one outermost row beginning from extreme ones; feeding hardening material in previously missed injectors in this row; supplying injectors of another extreme row with hardening material in the same way; feeding hardening material to ejectors of medium rows under 10-20 atm pressure; performing the second reinforcement stage as material hardens to obtain 70% strength. The second reinforcement stage involves forming vertical elongated flat massifs of secured ground anchored in mineral bottom by lower edges thereof and arranged at least in three rows, wherein each one includes at least three massifs. Massifs extend at the angle exceeding embankment slope angle to horizontal line. Massifs are formed with the use of double-slotted injectors in remainder embankment area. Injector slots are directed perpendicular to hydraulic pressure head vector direction in embankment area to be reinforced. Hardening material is ejected in above succession, wherein hardening material pressure is equal to design process pressure enough for direction of feeding hardening material through injector slots and lesser than hardening material injection pressure of the first reinforcement stage.

EFFECT: increased reliability of structure reinforcement; prevention of land-slide on structure slopes.
