Floor antierosion

 

The invention relates to a device for protection against erosion, water flows, soil banks, slopes, slopes, can be used in road, hydraulic engineering and land reclamation, and construction of pipelines on the slope. The floor is made in the form of carpet installed on the edge and repeatedly bent in opposite directions strips reinforced elastomer, United bends the bands or clamps elastomeric tape in a checkerboard pattern with the formation of ties each band with two connections. In the working position the carpet extend transversely of the strips, forming a multiple combination of diamond-shaped cells in the transport assembled in long flat pack. The invention allows to protect the soil surface from erosion by design, easily adaptable to the soil surface, requiring a minimum of installation work. 7 Il.

The invention relates to the field of work protection from erosion of soil banks, slopes, slopes in hydraulic engineering, road and drainage construction, and construction of pipelines on the slope.

Known protective coating of the slope, consisting of enlarged asnyk cells, adjacent of which are curved in opposite directions and mounted in staggered through equal distances flexible flat element, when this cell is bonded at points of contact of adjacent walls of the flat element (SU and.with. 1469008 A1, E 02 3/12).

A disadvantage of the known protective coating of a slope is that the design of his device pranoprofen against all of its elements: bond adjacent cells in strength is much less than the tensile strain of the flat flexible element; therefore, the tensile strength of the block along its longitudinal axis, generally significantly less than the tensile strength of the elastic flexible flat ribbon which is used to block. Accidental movements of a separate section of the block relative to the other sites that it is possible landslide when creeping on the shore ice in conditions of ice and raising the level of water in the stream channel drainage channel or river, the unit may be exposed to tensile forces along its axis. Picture loading places of fastening of adjacent cells block the contact point between the adjacent walls of the flat belt in this case is fully consistent picture of the loading of the tearing or splitting of the places of connection of Wahl is that the overlap, almost always, as we know, significantly less than the calculated force required to break the tension of a flat flexible element. It is obvious that the fastening of adjacent cells in the places of contact between the adjacent walls of the flat element by gluing or bonding metal clips, and even more end grooves will not sustain the load and will collapse. The block on the site of rastagenia stretches, will lose its geometric shape and prematurely ceases to perform the safety function of the slope.

Closest to the invention to the technical essence and the achieved results is the layer of anti-skid protection when containing carpet installed on the edge and repeatedly bent in the opposite side of the strip of elastomer reinforced textile yarn, and staggered the mount point of the curved sections of the strip that includes an additional set on the edge of a strip of elastomer, and the attachment of each strip to form its connection with two adjacent strips, with carpet in working with curved sections, position forms a transversely stretched surround the block with a diamond-shaped cells, and in the transport position is longitudinally stretched be the Los executed on the clips, rivets or glue, or by means of rings (and EN.with. 2005840 C1, E 02 3/12).

The disadvantage layer of snow is that the design layer of pranoprofen on all its elements, in particular point fastening strips less strong than the band, so when a random movements of sections of the Mat relative to the other areas that may, in landslides or creeping ice conditions ice may be destroyed under the influence of the forces occurring during the movement area of the carpet, fixtures streaks staples, rivets, glue or rings, which will cause premature destruction of geometric patterns and failure of structures. The destruction of the point of attachment to the staples, rivets or glue-like destruction of the connection of two flexible strips overlapping efforts on "the tearing or splitting of the connection, while the force required for rupture and splitting," much less known than the force calculated by the gap band. It should also be noted that the strip of mounting locations on the staples or rivets weakened by holes buckles or rivets, which leads to reduction of its strength in this place. The destruction of the fastening means is the following. The ring, according to the "Dictionary of Russian language" S. I. Ozhegov " (Moscow, 1987), is a subject in the form of a circle, in the technique of this word refers to the part of the rod, a closed circumference, if there is no explanatory definitions of the type: flat, oval, etc., and the cross section of the rod can have different shapes: round, square, etc., the Maximum size of the cross section of the rod, at least one order of magnitude less than the internal diameter of the circle. The material in this case, the most can actually be metal. Therefore, considering the width and thickness of the strip of carpet 10 cm and 0.8-1.5 cm, we can conclude that the diameter of the shank of the ring is equal to or less than the thickness of the strip. When moving a section of carpet efforts, pushing the strips from each other, are passed through the rings, which are located across the strip. The load ring on the strip is passed unevenly. A significant portion of the edge strip. The entire load perceives part of the cross section of the strip, i.e. actually the band in this place weakened (see Fig. 1. Shows a pair of strips 11and the ring 21at the beginning of loading). The tension in these areas significantly exceeds the allowable current level, which leads to the breakdown lane. It is also necessary to take into account the destructive efforts which are as follows: (see Fig.2) when significant force to overcome Flexural rigidity of the strip 11the last is bent relative to the rod, the ring 21with a bend radius equal to the radius of the rod 21or half the thickness of the strip 11while external stretched layers 31elastomer formed at such exorbitant inflection, breaks, 41the more likely, the more the elastomer of microcracks formed in it, not only during prolonged storage or use of the bands 11as the strip 11cut mainly from the former in the long term and unfit for further operation on the main purpose of the material, for example from old conveyor belts, but also in the manufacture of molded at the factory. Breaks 41open across the entire width of the strip 11access to the reinforcing layer 51for the influence of climatic and anthropogenic factors of the soil; after some time, the layer 51destroyed and thus significantly reduces the strip 11accelerating the destruction of the strip 11and carpet in General.

An object of the invention is the creation of a coating antierosion, the construction of which racto floor antierosion, containing carpet installed on the edge and repeatedly bent in the opposite side of the strips of elastomer reinforced textile yarn, fibers, metal-rope or cloth, including edge segments of the conveyor (conveyor) belt, and staggered fastening curved sections of the strips forming the connection of each bar with two adjacent, with carpet in the workplace, cross lanes, expanded position has a diamond-shaped cells, and transport forms a longitudinally stretched gapless package according to the invention has a fastening curved sections of the strips, made of reinforced elastomeric ribbon in the form of a multilayer bandage with sealed ends or clamp with fastened by stitching or staples ends.

The invention is illustrated by drawings.

Fig.6 - section b-B on the brace with bands.

Fig.7 - section b-B on the collar with stripes of the ons. The strip 1 is made of elastomer, reinforced textile yarn, fiber, cloth or metal-rope, for example, used conveyor belt. Bends in lanes 1 set of fastening the bandages 2 made by winding several layers of elastomer reinforced tape 3 and fastened by stitching or staples 4 ends. Fastening the bandages 2 are staggered to form the connection of each bar 1 with two adjacent bands is 1.

In the working position the floor spread across bands 1 with the formation of carpet diamond-shaped cells 5, in the folded transport in a dense package of strips 1 and roller 2. Alternatively, the attachment is in the form of a yoke 6 of the reinforced elastomeric ribbon 3 with stapled 4 ends.

The coating antierosion is as follows.

The coating is decomposed along the shore, slope, slope, and is moved in a transverse, relatively bands 1, the direction with the formation of carpet diamond-shaped cells 5. The cells 5 are filled with bulk soil, tamped. Install strips 1 at the edge creates an obstacle for ash soil from cells 5 surface water flows on slopes, slopes and banks. Also prevents ash g the water on the banks of rivers, drainage channels. Lanes 1, installed on the edge, promote adhesion of the coating to the surface of the underlying soil. So is the promotion and protection of the surface of the shore, slope, slope from erosion (erosion) water flows. In the event of a landslide or the creeping ice on the shore, it is possible to shift part of the cover relative to the other parts, while the strip 1 are tightened and effort from some of the bands 1 to the other is transmitted by a casing 2. Due to the elasticity of the band 2 of the reinforced elastomeric ribbon 3, the load on the strip 1 is distributed uniformly across its width, the radius of bend of the strip 1 when it is determined by the width of the bandage 2-L and its elasticity, and deliberately reaches large values relative to the thickness of the strip 1; bending the strip 1 are smooth, not sharp beyond bending the strip 1, so there are no conditions for disclosure of micro-cracks on the tension side of the strip 1. Band 2 is calculated by the same amount of load at rupture, and strip 1, while under condition of providing the necessary strength is selected estimated number of layers of tape 3 and its width L, which also determine the radius of bend of the strip 1. This ensures that ravnopravnosti coverage regarding everything ente 3 band 2 in the bend on the corners of the strip 1 when significant loads are possible extreme bending radii. Probable detection of micro-cracks on the tension side of the belt 3 in the first inner layer close to the external environment subsequent layer of tape 3.

Almost the coating is applied on slopes up to 30oto the horizontal, but slopes where excluded landslide phenomena and sliding ice during the ice drift, it can be used in order to save materials, tools, labor, clamps 6 of the same tape 3 in a single layer bonding the ends of the stitching or staples. In this case, the calculated strength of the clip 6 is ensured by selection of the width of the tape 3. the Necessity for protection of the clip 6 the next layer of tape 3 in band 2 no, because the clamp 6 performs the role of kinematic relations and practically not loaded.

The application of the invention will protect the soil surface from erosion (erosion) design high industrial availability, easily adaptable to the profile of the ground surface, reliable, durable, requiring a minimum of installation work and budget.

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.
