Abstract

The invention relates to geodetic instrumentation and can be used in land management. The aim of the invention is to increase reliability in operation. The lower threaded part 2 of the hollow rod 1 is made with longitudinal cuts and clamped by a ring 3 fastened to the tip 4. Above the carving part 2, the secret center is installed in the form of a metal ring 6 with radial cuts. Inside the rod 1, a conical truncated wedge 8 is placed. The sign is screwed down to a depth at which the secret center can be detected with a metal detector, and by applying a force to the rod 9, the wedge 8 acts through the ejector elements on the ring 6, fixing it in the ground. The sign is removed to the depth of the core installation and, by repetitively applying force to the rod 9, the threaded part 2 is expanded by acting on the wedge 8 on the inner surface of the latter. After filling the void that has formed in the soil with the fixing solution, monolithic bark 10 is formed. 6 Il.

Description

The invention relates to geodetic instrumentation and can be used in land management.

The purpose of the invention is to increase reliability.

Figure 1 shows the lower part of the sign., Longitudinal section; in Fig.2 a section aa in Fig.1; on fig.Z - section BB in figure 1; figure 4 - measles mark; figure 5 is a sign to the tab, the overall appearance; figure 6 is a sign embedded in the ground, a general view.

The sign - consists of a hollow rod 1 with threads oh lower part 2, made with longitudinal cuts and a conical inner surface. The threaded part 2 is clamped by a ring 3, fastened with a conical tip 4 and having protrusions 5, excluding its rotation when screwing the mark into the ground. A threaded part 2 has a concealed center, made in the form of a metal ring 6 with radial cuts and temporarily fastened to the rod 1, for example with glue, mastic, bitumen, rubber gaskets, etc. In rod 1, instead of fastening ring 6, holes are made, in which ejector elements 7 are placed, made in the form of levers and in contact with ring 6.

axis of the sign. But then the sign is removed to the depth of the installation of the box. At-. putting the vertical force to the rod 9, separating the tip 4 and expanding the threaded part 2, the diameter of the inner surface of which is larger than the diameter of the smaller base of the wedge and smaller than the diameter of its larger base. After which the voids filled in the soil are filled with a fixing solution.

As fixing solutions for sandy soils, a solution of urea-formaldehyde-5 hydrochloric resin with hydrochloric acid can be used, for clay soils - cement mortars. . The application of force to the vertical rod 9 can be provided in various ways. With the help of house blows, kratom, etc. I

As a result of penetration of the fixing solutions into the ground, dense monolithic measles 10 are formed, ensuring a reliable bond between the sign and the ground, and installing a secret center allows restoring the position of the sign in case of destruction of its upper part.

Claims (1)

Invention Formula Geodesic mark containing hollow bar with threaded bottom The elements 7 are supported by a truncated coni 35 with a part connected to the cone of the tumor wedge 8 with through channels for injecting fixing solutions. The sign is bookmarked as follows.40  Hollow rod 1 sec. the threaded part 2 at the end is screwed into the ground by applying force to the lever rod 9 to a depth at which detection of the secret center is possible, 45 for example, with the help of a metal detector in case of destruction of its upper part. Next, the rod 9 is inserted into the rod 1 and by means of the attachment to it of the rod, which is characterized by the fact that, in order to increase reliability, it is equipped with a metal ring with radial cuts installed above the threaded part AND with a tapered truncated wedge placed inside rods made with holes in which the inserted pushing elements are placed. In this case, the wedge is made with the possibility of longitudinal movement and successive interaction with the metal ring through the ejector elements and with The tical force is established by a secret inner surface of the threaded clock center by immersing the metal ring 6 in the ground, fixing it in the ground in directions, perpendicular to the ring, whose diameter is larger than the diameter of the smaller wedge base and smaller than its larger base diameter. part connected to the cone In order to increase reliability, it is equipped with a metal ring with radial cuts, installed above, made with longitudinal cuts of the threaded part AND with a tapered truncated wedge, placed inside the rod, made with holes, in which the ejected elements are placed . In this case, the wedge is made with the possibility of longitudinal movement and successive interaction with the metal ring through the ejector elements and with inner surface of the screw hour ti, the diameter of which is larger than the diameter of the smaller base of the wedge and smaller than the diameter of its larger base. fieL Fie.2 Fig.Z LLF FIG. five
