Description

The invention relates to fastening. earthworks and anchorage is chemically anchored. The known anchor with a chemical resin based on synthetic resins includes a supporting rod element and an ampoule with a polymer resin from synthetic resins l. After inserting it into the bottom of the well, the ampoule is destroyed by the supporting element of the anchor (rigid rod) and the components of the fixer are mixed by means of its rotation. The disadvantage of such an anchor is the possibility of securing the supporting elements only from rigid rods of relatively short length, since the destruction of the ampoule and mixing of the components is carried out by rotating the supporting element. Another synthetic anchor with a chemical fixer based on synthetic resins is also known. an ampoule with a chemical fixer, a locking device that holds the ampoule in the borehole, a carrier element and a cap mounted at its outer end 2. The disadvantage of such an anchor is that same is vozmo.zhnost securing the carrier members only from rigid rods relatively short length, since destruction of the ampoule is produced out by rotation of the carrier element. The aim of the invention is to extend the field of application of a chemical method of attaching to anchors with flexible bearing elements in deep wells. This is achieved by the fact that the end parts of the ampoule are provided with fixing screws holding its walls and interacting with the supporting element, passing through the holes in the ends of the ampoule. At the same time, the end of the carrier element is provided with an abutment and is placed outside the ampoule, with the possibility of moving in the direction of the wellhead during installation of the anchor. FIG. 1 shows the locking part of the anchor in a longitudinal section after entering it at the required depth into the rising squawokine; FIG. 2 - the same, but after fixing the lock; Fig. A longitudinal section of a secured lock in a downhole; FIG. 4 -: section A-A of FIG. one; FIG. 5 is a section along the line B-B of FIG. 2; FIG. 6 is a sectional view BB of FIG. The synthetic resin based anchor with a chemical fixer consists of a carrier element 1 and an ampoule 2 filled with a fixer, having lower 3 and upper 4 ends with glands 5, walls b and stopper 7. End holes 3 and 4 have through holes 8 through which the carrier is passed element 1, as well as transverse fixing screws 9, holding the walls of the ampoules and interacting with the supporting element. To limit the movement of the carrier when tensioned, its end is provided with an abutment 10, the Anchor is installed as follows .. Before installing the anchor in the revolving well (Fig. 1), screws 9 are fixed in the upper end 4 of the wall b of the ampoule (Fig. 4), ia the bottom end 3 is a common element 1 (Fig. 5), the end of which is placed outside the ampoule. Before installing the anchor in the downhole (Fig. 3), the screws in the upper end face are placed in the neutral position, and the walls of the ampoule and support element 1 are fixed in the lower end (Fig. 2). Then the ampoule 2 with the bearing element is injected into the well to the required depth and by moving the carrier element 1 to the side of the wellhead one of the ends (fastened with screws 9 to the walls of the ampoule) c Torio p in place and the other (fastened with screws the support element 1) is separated from the walls, while the fixer flows out of the opened ampoule and encapsulates the end of the anchor. After that, install the tip on the outer end of the anchor and tension it. The proposed construction of the anchor with a drop-down 1-pole allows for fixing the supporting elements of any gib. bones and lengths, which expands the scope of application of anchors that are fixed in wells by chemical means. Formula of invention. . ; 1.Anchor with a chemical fixer, including an ampoule with a chemical fixer placed in the well, a locking device holding the ampoule in the well, a carrier element and a cap installed at its outer end / characterized in that in order to extend the scope of application of the chemical method of anchoring to anchors with flexible bearing elements in wells of great depth, the end parts of the ampoule are equipped with fixing screws holding its walls and interacting with the supporting element, threaded through holes in the rtsah ampoules. 2. The anchor according to claim 1, characterized in that the end of the carrier element is provided with an abutment and is placed outside the ampoule with the possibility of moving to the wellhead when the anchor is installed.
