专利说明:

The invention relates to the field of anchoring elements (bolts). A known tubular anchoring element is made in the form of a pipe, into the cavity of which high-pressure fluid is supplied, which expands the element lj. The disadvantage of this device is the lack of reliability of fixing the element. Closest to the invention in technical essence and the achieved result is an expandable tubular anchor element, made with a longitudinal, reversed convexity. the inside of the tube is a closed recess with a perimeter of the cross-section, a large perimeter1) and the tube without depressions PQ. A disadvantage of the known device is the impossibility of its installation in a rock of a loose structure. The aim of the invention is to increase the reliability of anchoring elements in the Breed of any structure. This goal is achieved by the fact that in an expandable tubular anchor element made with a pro-ECOLEN & 4 with convexity inside the pipe 51Ci a closed groove with a perimeter of the cross section larger than the perimeter of the tube without a recess, the tube diameter without a groove is equal to; the largest diameter of the anchor element and the closed recess is made with a central angle greater than 180. The expanding-tube anchor elbment is provided with a sleeve with a skvo radial bore dp supplying fluid among the high pressure. In addition, the element is provided with reinforcing sleeves located at both its ends. FIG. 1 shows the device overall ID; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section B-B in FIG. one; in fig. 4 is a view of B in FIG. one; on fng. 5 - element fixed 3 holes, cross section; in fig. 6 - the same, side view; in fig. 7 the same, end view; in fig. 8 is a variation of the design of the ends of the element; on. FIG. 9 - the same, another option; Fig, 10 - the same, end view; in fig. 11 - 13 - the same, butt sealing phases; in fig. 14 - 16 - options of the element, side view; in fig. 17 another variant of the element, side view; in fig. 18 - the same, with the fixed element; in fig. 19 is the same, the cross section of the element; in fig. 20 however, a cross section with a fixed element; in fig. 21 and 22 are the phases of the connection of two elements in the drilled hole. The anchor element consists of a tube 1, the outer contour of which between points 2 and 3 forms an arc of a circle 4 with center b of radius r and central angle 0, which exceeds 180 °. The tube 1 is drawn out, twisted or folded so that it forms a depression which contains two curvilinear upper 6 and 7 and a curvilinear lower 8 of three. These areas may take the form of an arc of a circle (FIG. 3). The upper sections 6 and 7 are co. The D angle is greater than 180, and the lower portion 8 stands for point 5 and almost touches the outer part 4 of the tube. Reinforcing sleeves 9 and 10 are installed at both ends of tube 1, with the bottom end 11 inserted first and then sealed with a weld-12. A nozzle 14 is inserted into the upper end 13 and sealed by a weld 15. The anchor element is freely inserted into the opening 16 and expands under the pressure of a fluid, for example water. The outer circumferential part 4 of the tube 1 begins to be pressed into the walls of the drilled hole, and the recesses 6-8 bulge out. The length of the perimeter of the tube remains the area of the extension the same as before it. The pressure is applied to the walls 17 and 18 in the direction of the narrowing of the recess, as a result of which a force is created in the direction of the expansion of the recess, creating a cohesive force between the anchor element and the recess. According to the methods of joining short anchor elements (Figs. 21 and 22) to creep long elements, an element 19 having a connecting sleeve 20 is first inserted into the recess. After its expansion, the sleeve 20 is fixed by friction on the element and another anchor element 21 is inserted into it. contact with the sleeve 20. When expansion of this element occurs, it is fixed by means of the sleeve on the sleeve 20.
31,1446254
Thus, two anchor elements. The proposed device of the poet 19 and 2t and the connecting sleeve reliably form a single long anchor structure in the rock to fasten the anchor element. Element. ; 6-6 (Rig. 5 fj
