Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
The utility model relates to an annular passive side slope protection net which is suitable for mountain and steep hills with buffer zones beside building facilities, can intercept various flying stones outside building settings, and is used for protecting various high side slopes, high cut slope rolling stones and dangerous rock falling terrains and preventing rolling stones of slopes and mountain bodies from falling. The side slope protection net is a passive protection net.
As shown in fig. 1, 2 and 3, the slope protection net of the present utility model comprises a first steel wire net 1 and a second steel wire net 2, and a composite net is formed by using the first steel wire net 1 and the second steel wire net 2. Wherein, first wire net is woven steel wire net, and the mesh can be circular or polygon. The second steel wire net 2 uses a structure that a plurality of annular structural units are mutually sleeved to form a net, and each annular structural unit is formed by winding a steel wire rope formed by winding a plurality of steel wires; namely, a plurality of steel wires are formed into a steel wire rope, and then the steel wire rope is wound to form an annular structural unit. The ring-shaped structural units of the second wire mesh 2 are usually arranged in a circular ring shape.
When the annular structural units of the second steel wire mesh 2 are mutually sleeved, the annular structural units pass through the meshes of the first steel wire mesh 1 for a plurality of times, and in the process of passing through the meshes, the annular structural units pass through different meshes of the first steel wire mesh 1 back and forth. According to the perforation structure, the first steel wire mesh and the second steel wire mesh can form a sleeved connection relationship, so that the first steel wire mesh and the second steel wire mesh can be combined into a composite mesh. The second wire mesh 2 has a large mesh but has a better structural strength due to the use of a plurality of wire knots to form a ring-shaped structural unit. The first wire net 1 has small mesh, and can intercept various broken stones, rolling stones and the like. The first steel wire mesh 1 and the second steel wire mesh 2 form a composite mesh, wherein the second steel wire mesh 2 can be regarded as a function of strengthening the whole mesh body.
Fig. 2 is a schematic diagram showing only one of the annular structural units of the second wire mesh. Fig. 3 is a schematic view of a second steel mesh, the ring-shaped structural units and other ring-shaped structural units which can be contacted with the periphery form a sleeved connection relationship as far as possible.
When the utility model is used, the composite net is installed on the ground through a plurality of vertical support columns. Firstly, fixing vertical support columns 3 on the ground according to the required interval distance. Then, a composite net is disposed between the two vertical support columns 3, so that both ends of the composite net are fixed on the vertical support columns 3. Transverse supporting ropes 4 are arranged at the upper end and the lower end of the composite net along the length direction, so that the supporting ropes 4 pass through meshes of the composite net, can be meshes of the first steel wire net 1, and can also be meshes of the second steel wire net, and the supporting ropes 4 and the composite net form a hanging connection relationship. Two vertical support columns 3 are connected at both ends of the support line 4 at equal intervals. The support ropes 4 form a suspension support effect on the composite net. The support line 4 is in tension between the two vertical support columns 3. After the second steel wire mesh and the supporting rope are sleeved, the second steel wire mesh and the supporting rope can be bound by using steel wires, so that a stable connection relationship is formed between the second steel wire mesh and the supporting rope. The support ropes 4 are generally thicker steel wires.
Further, in order to improve the vertical stability of the vertical support column 3, two reinforcing anchor lines 5 are provided for the vertical support column 3. As shown in fig. 1, two reinforcing anchor lines 5 are respectively located at two sides of the vertical support column 3 and are symmetrically arranged in a diagonal manner with respect to the vertical support column 3. The reinforcing anchor pulling rope 5 is obliquely arranged, the upper end of the reinforcing anchor pulling rope 5 is fixedly connected with the upper end of the vertical support column 3, and the lower end of the reinforcing anchor pulling rope 5 is fixedly connected with the ground through the anchor rod 7. The reinforcing stay ropes 5 may be provided for all the vertical support columns 3 except the outermost ends, or may be provided in a single and double number, that is, every other vertical support column 3 is provided with a reinforcing stay rope 5 for a vertical support column 3. Or according to the distance, setting reinforcing anchor ropes for the corresponding vertical support columns 3 every 30-50 meters.
In a specific implementation, the outermost vertical support column 3 needs to be reinforced with a single-sided side pull anchor line 6. The side pull anchor lines 6 extend outwardly providing an outward stretching force to the vertical support column 3. The upper end of the side-pulling anchor rope 6 is fixedly connected with the upper end of the vertical support column 3, and the lower end is fixedly connected with the ground through an anchor rod 7.
The reinforcing anchor rope and the side anchor ropes can be provided with pressure reducing rings generally, the pressure reducing rings are composed of spiral annular steel pipes and fixing pieces which are closely arranged, the steel pipes spirally encircle at least one circle, and the ends of the steel pipes extend out from the tangent line of the spiral after crossing. When in use, the steel wire rope penetrates from the opening at one end of the spiral steel pipe and penetrates out from the opening at the other end of the steel pipe. The impact force received by the steel wire rope can be effectively absorbed and relieved by the pressure reducing ring, and the pressure reducing ring has the advantages of simple structure, strong adaptability and low cost. The decompression ring is purchased and used, and the decompression ring is frequently used in anchor pulling systems such as anchor pulling ropes.
