Definitions

  • the technical solution relates to the field of construction, utilities or agriculture and can be used in the creation of metal fence posts.
  • the fence is a fence, consisting of supports and canvas, fixed on the supports between them.
  • supports (pillars) of fences (fences) are made of metal pipes of rectangular, less often round, section, due to the fact that rectangular pipes have greater bending strength; and are also easier to install due to the fact that they have flat edges, regardless of the method of installation, including installation by welding.
  • rectangular pipes are easier and more efficient to transport and store, since in this case more usable area and volume are used.
  • the installation of the fence fabric on pillars (supports) of rectangular section can be carried out in many ways, for example, using consoles fixed on the planes of the pillar, brackets for cross members on which the fabric is mounted; using U-shaped strips for fastening between them the lamellas of the canvas; using eyelets with a hole for attaching mesh sheets to them; and in similar ways.
  • the flat edges of the posts of rectangular cross section also make it possible to simplify the process of mounting the fence fabric due to the simpler installation of the fasteners for the fabric itself, which makes it possible to simplify and speed up the installation process of the fence (fence) as a whole.
  • Other characteristics of the pole (support) for the fence (fence) may relate to its height, which, as a rule, does not exceed three to four meters, depending on the characteristics of the fence (fence) canvas.
  • the point foundation for the support is performed: a) by pouring concrete or backfilling with a specially prepared sand and gravel mixture into pre-drilled pits with simultaneous installation of the support; b) as a foundation block in the form of a "shoe", a screw support or a tubular driven support; at the same time, in general, the installation of supports should be carried out in one of the following ways: a) concreted into a strip reinforced concrete foundation; b) fasten the support to the foundation through a flange connection using a flange connection; c) fasten the support to the foundation with anchors.
  • the support When using a point foundation, the support should be installed: a) in a specially prepared sand and gravel mixture or concreted in pre-drilled well holes; b) either by driving a metal pile into the ground with subsequent fastening of the support to it with bolts through a flange connection; c) or by fastening the support with bolts through a flange connection to a pre-installed screw support.
  • screw and driven supports can be used on soils of any type, except for rocky ones.
  • a ground anchor can serve as an alternative to a driven or screw pile (see, for example, GOST R 57355-2016 / EN 1537:2014 "Ground anchors.
  • Ground anchors are installed in a pre-drilled well with subsequent concreting or compaction with a sand-gravel mixture and serve to strengthen the structure or to fasten a building element to the ground on slopes.
  • expansion anchors for fastening in concrete are known (see, for example, GOST R 56731 -2015 "Mechanical anchors for fastening in concrete. Test methods").
  • Such expansion anchors cannot be used for fixing supports. fences directly into the ground due to their small size, however, this technique can be used to create expansion ground anchors.
  • a driven pile is known as described in patent RU 139587 U1 (D1).
  • the driven pile known from D1 consists of a metal perforated pipe with a conical tip, having holes provided with opening and closing metal plates fixed on the pipe, with a removable tee with a metal cover located on the upper part, and the lower part of the perforated pipe has longitudinal slots that form cantilever blades, and the tip is made in the form of a cylinder, turning into a truncated cone, ending with a cone-shaped tip.
  • Immersion and operation of a driven pile known from D1 designed to strengthen the base with a broadened heel and cementation of soils, is carried out as follows.
  • the supply of cement mortar into the pipe and its immersion is carried out simultaneously, which causes the metal tip to move along the longitudinal slots at the end of the pipe and creates the conditions for the formation and symmetrical rotation (bending) of the cantilever blades 6 from the reactive pressure of the base soil to the outside of the pipe, while creating the necessary a gap between the pipe and the surrounding soil, into which, through ellipsoidal holes, squeezing the plates, the solution to be fixed is pumped under pressure.
  • the cantilever blades move apart from the reactive thrust of the soil and are fixed in the cement stone, increasing the area of the pile support, creating a broadened heel and increasing the bearing capacity of the pile.
  • the driven anchor pile known from D2 includes a rod-rod, around the shaft of which a round-section anchor head is mounted with a gap (see Fig.
  • the performance of the anchor pile during immersion is achieved by driving the rod-thrust together with the pipe into the ground, opening the anchor head - by driving it with an inventory pipe in the ground, in during operation - due to the possibility of applying a pulling load to the rod-thrust.
  • the anchor pile is driven into the ground by means of a rod to the design mark. Due to the presence of a gap between the outer diameter of the anchor head pipe and the outer diameter of the tip (2-5 cm), the pile plunges into the ground without obstacles.
  • the blades of the anchor head are opened in the ground by driving (see D2: Fig. 2) by means of an inventory pipe.
  • the blades of the anchor head in this case, due to the presence of slots, bend in an unstable or previously weakened place (half the length of the slots) and turn into a "flashlight" in each tier.
  • the anchor pile is capable of receiving a pulling load, turning the rod into a thrust (see, D2: Fig.
  • a metal pole known from DZ mainly for a fence, contains a support post and a part loaded into the ground, which is made of a cylindrical pipe and equipped with a cutting helical blade, characterized in that the support post is made of a profile pipe with flat edges, the upper end is buried in its lower part said cylindrical pipe to form contact with the male surface, and the pipes are connected by welding along the contour.
  • the pillar known from remote sensing has a number of significant drawbacks.
  • the pole known from the DZ is difficult to manufacture - to create it, it is necessary not only to make the recessed part with cutting blades, but also to ensure its connection with the profile pipe of the support post (that is, with a square metal pipe, in fact, a pole (support ) for the fence).
  • the column known from the remote sensing is connected to the ground through screw connection, which reveals the following disadvantages: 1) unreasonably large efforts are required to screw the post into the ground, and the possibility of using manual screwing devices is excluded - such suitable manual devices simply do not exist, and known manual devices for screwing piles cannot be used, since they can be used, in fact, only for screwing piles of small length - for piles of large length, the use of special heavy equipment is required; 2) the denser the soil, the more leverage is required for manually screwing the screw post into the ground, which can be a critical disadvantage, since with a large length of the fence (fence) web, spans between the posts (supports) should be less frequent to create greater operational reliability of the fence (fence) as a whole, and thus the required length of the lever may exceed the length of the span, which will lead to the impossibility of mounting such a screw post; 3) the longer the recessed part of the screw post, the higher the height of the wrench should be placed, which leads to the fact
  • the screw column known from DZ has an increased complexity of installation; in addition, the installation of such a screw post is not convenient enough and may require the selection of a workforce of high stature, as well as a large number of labor; in addition, the installation process of the screw post is longer.
  • the pole known from the remote sensing provides insufficiently reliable fixation in the ground, since such a pole can easily be subjected to unauthorized extraction by simply twisting it in the opposite direction, which is critical for situations where the fence (fence) is not under constant supervision; in particular, the ease of extracting the screw post can attract unauthorized assemblers scrap metal.
  • the installation of the column known from the remote sensing does not imply the possibility of strengthening the connection created with the soil with reinforcing mortars or reinforcing bulk materials, since such a connection and the design of the column known from the remote sensing do not imply their use at all and there are no opportunities to fill or fill connection with reinforcing solutions or bulk materials, in particular, the column known from the DZ in the recessed part is solid, without holes, which does not allow spilling (spilling) the solution (material) through the column into the junction, and the installation of the column known from the DZ does not imply the creation of any - or a well through which access to the ground connection is possible.
  • the technical problem solved by the claimed technical solution is the creation of the closest analogue of the method of mounting a fence post, which does not have disadvantages, provided by the creation of a fence post with the possibility of anchoring with the ground, providing: 1) ease of its manufacture, including directly in the process installation; 2) ease of installation and, as a result, ease of installation of the fence as a whole, as well as, as a result, increased ease of installation of each pole separately and, as a result, the fence as a whole, as well as, as a result, reduced labor requirements and less labor to install one fence post; 3) a more reliable connection of the fence post with the ground and a significant complication of its unauthorized extraction.
  • the technical results achieved by implementing the claimed technical solution are: 1) simplifying the manufacture of a fence post; 2) simplifying the installation process and increasing the ease of installation of the fence post and, as a result, simplifying the installation process and increasing the ease of installation of the fence as a whole; as well as, as a result, reduced labor requirements for the installation of a fence post and, as a result, the fence as a whole; 3) reducing the amount of labor required to install one fence post; 4) as a result - an increase in the speed of installation of each fence post, and, as a result, the entire fence as a whole; 5) increasing the operational reliability of the fence post and significantly complicating its unauthorized removal.
  • the technical result 1) is achieved due to the fact that it is not required to manufacture the recessed part of the fence post with a cutting blade and, as a result, it is not necessary to manufacture the fence post in two parts, but it is enough to use a rectangular metal pipe of the required length and make longitudinal slots at the same level in the ribs of its buried part, which will make it possible to create an anchor connection with the ground by deforming pipe sections, the perimeters of which are limited by the beginning and end of the corresponding slots, in the direction of the ground.
  • the technical results 2), 3) and 4) are achieved due to the fact that it is not required to perform the operation of screwing the column for the fence into the ground, but it is enough to prepare the well, place the claimed column in it and create an anchor connection with the ground by deformation of pipe sections, the perimeters of which are limited by the beginning and end of the respective slots, in the direction of the ground, which can be carried out by one of the tools described in detail below; at the same time, it is not required to use any levers that are mandatory when screwing the screw post; at the same time, obstacles for installing a pillar in the form of, for example, stones can be detected even when well drilling and eliminated prior to post erection, without requiring removal of the post to access the obstruction; in this connection: a) only one person is required for the installation of one declared pole, and the installation of high poles does not require a workforce of high growth, since the installation is carried out using specialized tools; b) since only one person is required to install one declared pole, other employees of the installation
  • the technical result 5) is achieved due to the fact that created by deformation of pipe sections, the perimeters of which are limited by the beginning and end of the corresponding slots, in the direction of the ground, the anchor connection with the ground provides increased operational reliability due to the reliability of the connection of the column with the ground , as it provides at least four engagement surfaces (by the number of deformable sections), the area of which can vary in the length of the slots even after the manufacture of the column, in contrast to the screw connection, where the engagement surface is limited by the width of the cutting blade, which cannot significantly exceed the limits of the section of the screw column , as this, when screwing, will lead to the formation of a too wide well; in addition, the proposed anchor connection does not involve the extraction of the claimed fence post by simply pulling it out (this is prevented by the petals formed by the deformed sections), or unscrewing (this is prevented by the absence of any cutting blade in the recessed part), and therefore the unauthorized extraction of the claimed post after its installation, it is significantly complicated and requires excavation to a depth exceeding the depth
