Wire mesh for gravel fencing or to protect the surface soil layer, and method and device for its manufacture
The invention relates to a wire mesh for gravel fencing or to protect the surface layer of the soil. Wire mesh laid on the ground surface or mounted in a nearly vertical position on the slope and woven of stainless wires. What's new is that the wire in the wire mesh made of high-strength steel, having a nominal strength in the range 1000-2200 N/mm2and as such steel wire used stranded wire or wire made of spring steel. New in the method of manufacturing wire mesh, consisting of a spiral bent wire is that the wire of high strength steel is served at a certain angle of inclination equal to at least (), on the mandrel for bending about 180so that the wire again pushed along its longitudinal axis up to the mandrel for bending and bend 180with a certain length (L) around a mandrel for bending up until the wire becomes a spiral. New device for implementing the method is that the mandrel for bending set so that between it and the guide area Suslina of high-strength steel, angle () around the mandrel for bending about 180when this is provided by the input device to propel the wire length of about (L) along its longitudinal axis in the guide area. The technical result of the invention is to create a cheaper and lighter coverage with a distributed weight for easy Assembly on the mound or gravel buttress. 3 S. and 7 C.p. f-crystals, 14 ill.The invention relates to a wire mesh for gravel fencing or to protect the surface soil layer, woven from corrosion-resistant wires and either laid on the ground surface, or fixed in an almost vertical position on a slope or in any similar place.The famous wire mesh, which is very often used, formed of wire mesh hexagonal cells, as shown on the attached drawing (Fig.8). This wire mesh is made of galvanized steel wires with low values of Flexural strength and elongation, so that the wires can be braided with weave. The hexagonal shape of the individual cells is manifested later in repeating the TFR is the management of the grid, and a separate wire between them are on the diagonal. In the form in which they are made and applied, these wire mesh form a nearly two-dimensional profile, i.e. with respect to the cross section of such wire cell formed almost linearly, because - due to their low resistance - this wire can be bent into any profile, expending less power.These wire mesh rolled into rolls for storage and transportation, and for this they need a lot of space. When you expand these cells to the Assembly site at the same time another drawback of the latter is the fact that after you expand these cells very quickly discovered and expanded themselves.When using such wire grids as structural elements of the protection embankment on steep unstable slopes shall be reinforced twisted wires that pull over equal intervals in a diagonal, longitudinal and/or transverse directions over a wire mesh, or woven into the latter. In addition, they should provide marginal gains, and it is necessary to provide mounting, fixed in the ground at equal intervals in the outer coat support for the surface layer, in respect of which there is a risk of landslide or debonded surface area.However, the wire mesh at a heightened risk of a breakdown in places twisting.The famous wire mesh for gravel fencing or to protect the surface soil layer, woven from corrosion-resistant wires and laid on the ground surface or mounted in a nearly vertical position on the slope (application JP 58-002295, 07.03.1083, E 02 D 17/20).The drawback of such grids is that they occupy a lot of space in storage and transportation, as well as insufficient protection embankments and reinforce the layers of vegetation and humus.The present invention is the creation of wire mesh, corresponding to the type mentioned at the beginning, which is formed in such a way that when it is in contrast to the well-known wire mesh - is more cheap and easy coverage with distributed mass for easy Assembly on the mound or gravel buttress. In addition, using this wire mesh as protection of the embankment, you can create better conditions for strengthening layers of vegetation or for maintaining humus on the spot or layers deposited on covered is that of the laid floor. In addition, this wire mesh must be made with the possibility of folding to save space during storage and transport.According to the invention the problem is solved due to the fact that a wire grid for gravel fencing or to protect the surface layer of soil, laid on the ground surface or mounted in a nearly vertical position on a slope, woven stainless wire, the wire is made of high-strength steel, having a nominal strength in the range 1000-2200 N/mm2and as such steel wire used stranded wire or wire made of spring steel.It should be noted that in the further description, the term "high strength steel" will mean "steel, designed to work in difficult conditions".In comparison with the known wire mesh, by using this wire mesh corresponding to the invention, with an estimated nominal strength for a given coverage area, the weight can be reduced by more than half, and the result should be a substantial cost savings for the required material, as well as disassembly and Assembly of such a grid. In addition, ensite risk occur during the installation of a ladder.It is reasonable plexus wire mesh of a single spiral-shaped bent wire, causing the wire, respectively, will have an angle of inclination () is preferably in the range of 25-35.Due to its high Flexural strength even in the tense condition when using this wire mesh in accordance with the invention is obtained three-dimensional or Copacabana structure. This grid can be used to cover the soil, such as embankments, and in addition, for in-place hold or stabilize the layers of vegetation or layers deposited on the coating.An additional advantage of this wire mesh is that the mesh, which consists of twisted, single, spiral-shaped bent wires, can be folded, so it takes up less space during storage and transportation.Various specific embodiments of the invention and its other advantages and more are explained below with reference to the drawings, where:Fig.1 shows a top view of wire mesh, corresponding to the invention,f is a perspective view of the wire mesh, corresponding to the invention, as protection embankments,Fig.4 shows a view of a gripping plate protection embankment corresponding to Fig.3,Fig.5 shows a partial cross section of the protection of the embankment corresponding to Fig.3,Fig.6 shows an image of a top view of the wire grid with gravel envelope buttressFig.7 shows an image of a side view gravel enclosing rib corresponding to Fig.6,Fig.8 shows a schematic partial view of the famous wire mesh with twisted wires,Fig.9-11 show a perspective view of the device used for the manufacture of wire mesh in different operating positions, andFig.9a-11a show in each case an image of the front view of the device in its operating positions corresponding to Fig.9-11.In Fig.1 shows the wire mesh 10 to protect the surface soil layer, for example for the protection of embankments or for the protection of stone walls on the street or anywhere in the same place. In this case the wire mesh 10 is composed of twisted wires 11, 12, 13, 14 and held in place by a certain system of relations created using fasteners 15, which are immersed in the soil. These wires are usually ocenka, in order to achieve the desired corrosion resistance. In addition, it is envisaged, for example, zinc coating with a surface weight in the range of 100-250 g/mAccording to the invention, the wire 11, 12, 13 and 14 in the wire mesh 10 is made of steel, designed for operation in harsh conditions. Preferably, these wires 11, 12, 13 and 14 use wire that is twisted with the formation of twisted wires. According to the standard DIN 2078, such wire, as these have a nominal strength in the range 1000-2200 N/mm2such as wire, which has a tensile strength of 1770 N/mm, But you can also use wire of spring steel, conforming to DIN 17223. Wire thickness is preferably in the range of one to five millimeters. It depends on the required tensile strength.Wire mesh 10 is formed from a rectangular diagonal grid, in which a separate spiral-shaped bent wire 11, 12, 13, 14 have some angleand some of the length L between the two folds that define the shape and size of the cells 17 in a wire grid 10. As the angle of inclinationpreferably choose the angle of the PA cell is for example, 77143 mm This gives the advantage that the grid 10 is not under significant tension, if it is laid on the ground surface and stiffen the cables 21 in its longitudinal direction after the tension. And, as a result, individual cells 17 form rhomboid with an elongated opening, which provides the advantage of lower permeability for the material of the ground.On the sides of the wire 11, 12, 13, 14 are elastically connected to each other in pairs by means of hinges 11’, 12’, and these loops 11’, 12’ formed by the wires, bent at the lateral ends. In addition, after they are bent to form loops, the wire preferably provide multiple loops 19 which are wound around its circumference wires that, due to the tensile load on these loops, ensures adequate security to prevent their disclosure.Within the scope of the claims of the invention this leads to the additional advantage that a separate wire is resiliently held together with each other in a bound state, resulting in that the wire mesh 10 can be folded or collapsed Velino at the wire 11 is passed, the wire or cable 21, located on the upper and lower end of the grid 10 and which, in turn, stretched on the ground by means of fasteners 15 or similar devices. However, in principle, on the fasteners 15 can also actually hold the wire loop 11.According Fig.2, the grid 10 has a three-dimensional Chupacabras structure, which in this case can be obtained by the use of steel wire designed for operation in harsh conditions. For this purpose, the individual wires 11, 12, 13, 14 are bent to receive the spiral profile, and the grid 10, resulting in its cross-section forms an almost rectangular profile. Therefore, the wire consist of bent sections 11’ and straight sections 91. This elongated rectangle has a thickness several times the thickness of the wire. In result of this, a wire mesh 10 is also formed in the hard condition, but not in nearly linear or polusobrannom, known as wire mesh, corresponding to Fig.8, but is three-dimensional. On the one hand, this leads to the grid of the properties of high elasticity, because the wire can be tensioned with high rigidity in their longitudinal direction and give this provolo the CSOs three-dimensional structures obtained bearing or achieved the strengthening layers of vegetation, placed on this grid or a sprayed on coating.In addition to the width of the cell, you can change the width 10’ grid 10 in accordance with its application. This thickness 10’ is determined when the bending each wire 11, 12, 13, 14. It accepts values that are multiples of the thickness of the wire, and preferably greater than the thickness of the wire 3-10 times, as shown in Fig.2.In contrast to the known grid with hexagonal cells, as shown in Fig.8, the grid, because of the almost straight line of the magnetic flux, resulting in a diagonal direction, the formation of the optimal flow of energy and consequently improved strengthening covered ground. Local magnetic effects on the wire mesh in the diagonals passed on to her side and simultaneously absorbed various mounts.Fig.3 shows the wire mesh 10, corresponding to the invention, in the form of protection 40 mounds, such as a mound, which is located on a steep slope 45, which forms the surface layer of the soil to be protected. This protection 40 barrows consists of wire mesh 10, which is placed over the desired area of the mound, and fasteners 15, which are immersed in the ground by means of gripping plates 15’ or similar crutches for soil or rock, which preferably are fixed at regular intervals on the mound 45. On the upper and lower end of the grid 10, respectively, provided the cable 21 through which the grid 10 pull, applying traction force.Fig.4 and Fig.5 shows the gripping plate 15’ which, as shown, consists of a round, oval or has another form of sheet material and of different hooks 15, which are bent at right angles, are down made of sheet material and, accordingly, are wedge-shaped. Each gripping plate, indicated by the position 15’, is pressed by the fastening 15 in the wire mesh 10, and it creates a permanent protection embankment 45 through the wire grid 10, which affects the whole bearing surface. Due to their wedge-shaped grippers 15, which pass through the grid, called "joining" with wire mesh.In the case of soft ground conditions, to give rigidity which, as defined above, possibly with attachments, you can put fabric pillow, the size of which can be more than one square meter, under the gripping plate 15’ and under the net, then resistant to climatic influences fabric pillow: size, loboko cracked bedding soil, even in those places where there are voids between the surface of the mound and the net, to establish contact can also be stacked such fabric pillows like these.This particular option exercise shows that, on the one hand, simpler Assembly, and on the other copacobana the grid structure 10 results in improved coverage. These piles 45 often formed by steep slopes and are therefore very difficult. Even have to lay a grid with the help of helicopters. If such a net, in contrast to the known, now has mass, reduced by half, then it can be transported and moved with correspondingly lower costs.This protection 40 mounds can be used for various purposes, for example in accordance with this drawing, to prevent erosion of the surface layer 45 of the soil, and when used with gravel, at the breaking of stones and blocks or anything like that, when shedding surface layer of the ground or Foundation for the root layer of plants that occur on these mounds.In Fig.6 and 7 shows the wire mesh 10, corresponding to the invention, for use gravel the other items that usually slide at high speed, being directed edge in the lowlands. This wire mesh 10 is installed in an almost vertical position almost at right angles to the mountain slope 25 and the installation process is attached to the support posts 55, made of steel, which are respectively fixed in the ground 56. Wire mesh fixed by means of wire ropes 52, passing over and under the horizontal braces 53, whereupon this mesh braided wire ropes 52 with a corresponding delay. On the one hand, delays 53 are held on the support posts 55, and the other is attached and pulled by their dilatory ends 53’ each to one basis or something similar.Due to the elastic spring properties of the grid 10 of the wire, designed to work in harsh conditions, high values of kinetic energy, which take place in case of an impact with rocks or tree trunks, can be reduced. Local magnetic impact hits stone or something similar is evenly distributed in all directions. This raises the additional advantage of wire mesh, corresponding to the invention, since the which are within the range of elasticity, which is many times more able to absorb much greater effort, as a result, in addition to lower costs of manufacture and installation, requires much less maintenance work.In Fig. 8 shows a known and proven wire mesh, which is discussed in the introductory part, and therefore its detailed description is omitted below.In Fig.9-Fig.11 shows a device 60, by means of which the method of manufacturing the wire grid 10, is made of single wires 11 made of steel, designed for operation in harsh conditions. This device 60 essentially comprises a base 61 with a rack 62, the drive rotation 63, flexible node 65, which is connected with the latter by means of a rotary impact, as well as mandrel 66 for bending. Swing drive 63 is attached to the rack 72 and actuates the lathe Chuck 68, which serves to support the flexible node 65, whereupon the horizontal axis of rotation of the latter is oriented concentric with the cylindrical mandrel 66 for bending. The guide plate 64 has a horizontal guide zone 64’ is adjusted so that between it and the mandrel 66 for bending, which is also horizontal, there is a gap. The rotary support plate 73 node gibberosa 63. In addition, the guide groove 72, the stop 73, the rotation axis 74, which is regulated before the last, and holding the connection 75, which has a clearance of 75’ attached to this node 65 flexible and all together are held on the rotary support plate 73.According Fig.9 or Fig.9a, the wire, which is made of steel 11 designed for operation in difficult conditions, is directed in the transverse direction through the gap between lathe Chuck 68 and the supporting member 71 in the guide zone 64 under the mandrel 66 for bending. Then she popped the guide chute 72 up to the stop 73. This can be done mechanically by the conveying device, which is not shown in more detail. The wire 11 is aligned with the mandrel 66 by means of this guide channel 72, acquiring the angle of inclinationand has length L from the mandrel 66 for flexible until it stops. This angle of inclinationand length L, which if necessary can be adjusted to define the shape and size of the cells 17 in a wire grid 10, as mentioned above. The axis of rotation 74 is also used as a guide, if the wire 11 is bent so that, in addition to the above, moving away from the axis of rotation 74, wires of the second actuator 63 around the mandrel 66 for flexible, consequently it shows in almost vertical position.Because the flexible node 65 is rotated 180and, in accordance with Fig.11 or Fig.11a, is almost parallel over a guide area 64, the wire 11 to which they are centered, also bent around a mandrel 66 for bending about 180. As a result, this node 65 flexible again gets the opportunity to return to its original position, shown in Fig.9, in which the wire 11 remains in the bent position. After the turn of the node 65 flexible back the wire that went around the mandrel 66 for flexible, is pushed forward again along its longitudinal axis and then up again to the stop 73 and centered on the pivot axis 74 or in a holding connection 75. After following this turning movement is performed accordingly. After repeated rotation of the block 65 flexible forward and backward 180and the subsequent ejection of the wire is obtained obviously a spiral wire with bent sections 11’ and straight sections 91 in accordance with Fig.11. This process has the advantage that the constant increase of the angleas to the bent portion 11’ and Poty device 60, the latter can be woven together with the formation of the wire mesh 10 in the usual manner. For this purpose bent wire mesh with each other until, until you have a wire of the desired size.The invention is adequately illustrated by the above specific implementation options. Of course, this wire mesh can be given and a different structure. So, for example, a single wire could not bend as shown. The angle of inclinationin the illustrated specific embodiment, is approximately 30however , if you want, you can provide an angle in the range 1545.The invention is suitable for all types of coatings, surface layers of the soil, for example, even for the surface layers of soil in underground mines. Thus, as shown above, the walls and arches in the tunnels, hangars, caverns or similar areas can be covered and, accordingly, to strengthen, using these wire mesh, corresponding to the invention. In the case of coatings of tunnels that are cheap in construction, any loose or broken piece of rock from the walls without any risk for life the toboggan way for reinforcing or strengthening layers of foundations in the construction of highways, or road construction, or in the case of construction sites with these nets connected to the corresponding substructure or superstructure. Moreover, it can be used for reinforcement surfaces of asphalt or concrete, for example surfaces, in which cracks are sealed with bitumen or by hydraulic means.
