The invention relates to a device for strengthening the side slopes of roads, slopes and coastal embankments and can be used as them in view of what Dosov roads, slopes and coastal embankments, contains many cross-shaped elements made with the possibility of their frame with niches to fill the ballast ground, and clips of their situation (RF patent N 2032022, IPC E 02 D 17/20, 1995).

Cruciform elements of this protective coatings require precision manufacturing to ensure reliable fixing in the Assembly work, which increases labor and material costs.

Known protective coating of the cross-shaped elements to strengthen the side slopes of roads, slopes and coastal embankments with education or frame with niches to fill the ballast ground (patent EPO N 0273 541 B1, E 02 D 17/20, 1991).

The specified protective coating suitable for strengthening the side slopes of roads, slopes and coastal embankments with the installation of its predominantly at the base of the embankments, as a cruciform elements are intended to prevent the spread of soil and are heavy.

Closest to the invention in its essence and the achieved result is a protective coating for reinforcing the side slopes of roads, slopes and coastal embankments containing many cruciform elements flat is every fifth cruciform element from one to three neighboring toe cruciform elements and binding together they eyes of rod clamps, passed through them with the opportunity to implement their ends in the main ground (see, for example, CH A, 13.08.82).

The disadvantages of the known constructions is the presence of gaps between the flat cross-shaped elements when mounting them stand vertically, which does not exclude the penetration of loose fine-grained material (sand) and it leaks through such coverage; the unsuitability of flat cross-shaped elements to strengthen inclined slopes, because the depth of their niches too small, the amount of NIS depth is determined by the thickness of the flat part of the cross-shaped elements; by strengthening inclined slopes with several layers of crossed elements inefficient in their use because of the gaps between them and wasteful use of materials, gaps will lead to the diversion of fine-grained material and erosion of slopes.

The present invention is the elimination of leakage of material and erosion of the slopes, increased stiffness, increased the adhesion of the coating to the ground.

The problem is solved due to the fact that the protective coating to strengthen the side slopes of roads, slopes and coastal embankments, contains many cross-shaped elements with flat every fifth cruciform element from one to three neighboring toe cruciform elements and binding together they eyes of rod clamps, passed through them with the opportunity to implement their ends in the main ground, according to the invention adjacent flat heel with eyelets at each cross element offset height from the reference surface, one relative to another by the thickness of the flat heels, and cross-shaped elements provided with ribs longitudinally spaced with their crossbars, and lugs made on their supporting surfaces.

This cross-shaped elements can be made of a thermoplastic material such as polyethylene, nylon or vinyl plastic.

These distinctive features are essential, because each of them separately and together is aimed at solving the problem and achieving a new technical result.

The presence of a flat toe with the lugs on the cross elements improves the reliability of fastening of cross members between themselves and with the main soil to form the frame of the protective coating with different sizes niches during installation to fill the ballast ground lugs are fastened to each other and the ground of a single rod-like anchor. Depending on the inclination of the side slopes of roads, clonminam niches. If the angle of the slopes, the slopes of the highest, can be selected frame with the smallest size of niches in this case, each flat heel of each cross-shaped element attached overlapping three flat heel adjacent cross members. If the angle of the slopes, the slopes of the least, it will select the frame with the largest sizes niches. In this case, each of the heel of each cross-shaped element is attached overlap one flat heel adjacent cross member. When the flat heel of each cross element are attached on two flat heel adjacent cross members, in this case, it turns out the frame cover with intermediate sizes niches between the maximum and minimum dimensions. The presence of rod anchors increases the reliability of fastening of cross-shaped elements together in their superimposed overlapping flat heels and fixation on native soil. This combination of functional properties increases the efficiency and reliability of the use of protective coatings in the proposed design. Run flat toe offset one relative to the other in each cross-shaped element extends the range of installation Otomi each of them on the supporting surface has a lug. Supply cruciform elements edges, longitudinally arranged slats in the form of a cross, which increases rigidity and allows you to choose the profile of increased stiffness at the lowest weight of the frame cover, which reduces the consumption of materials for the manufacture of cross-shaped elements. Performing cross-shaped elements from a thermoplastic material such as polyethylene, nylon or vinyl plastic, accelerates the production of cross elements industrial way, increases the service life of the protective coating that provides resistance to the effects of atmospheric environments and weather conditions.

One set of new essential features with commonly known essential features in the proposed protective coating allows to solve the problem and achieve new technical result, expressed in the creation of different structures coverage increased reliability and durability, ease of manufacturing industrial method that characterizes the proposed solution significant differences from the prior art, analogs and prototypes.

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.
