Anchor piping system consists of immersed on both sides

pipeline I into the ground to a greater depth and connected with each other on the upper part of the surface of the pipeline tapes, which are closed in the soil under the pipeline into the coils forming the rings 2 or spiral 3.

The device for immersion in the anchor belts consists of a self-propelled chassis (not shown) with a stand 4 supporting a pipeline and having a grip of 5, and symmetrically located on the grip hollow rods 6 and 7 moving in one plane with 8 drives, cylindrical guides 9 and ribbon-caps 10 and 11. Rods 6 and 7 are made concentrically bent in the plane of their mutual arrangement, mounted with tips 10 and 11 towards each other and provided with stops 12 of mutual contact of the latter. The tip 10 is made with a through transverse groove 13 in the form of a comb with lumens 14, the tip 11 is made in the form of a fork 15 with tapered teeth I6 located in the planes of the gaps 14 of the comb groove 13 of the tip 10, and is equipped with additional tape-piercing bar 17. Each of the teeth 16, the fork 15 is made with a through transverse groove 18, and each of the pins 17 is made with a length less than the height of this groove 18, is placed into it and

its blunt end is attached to the head of the 16 plug at the tip of the latter by means of a limited rotational spindle finger 19. Each of the NIKS 10 and 11 tips is mounted on the pipeline grip 5 by means of a longitudinally movable (along a linear guide 20) slider 21 supporting the console 22 of the cylindrical guide 9. The support is adjustable in two planes by rotating the permutation of the flanges in the flange joints 23 and 24. In accordance with the Dani method of anchor system, they are immersed on the sides of the pipeline I into the ground and the greater depth of the hollow rods 6 and 7 are carried out by tapes in the cavity of the rods and the ends of the tapes are tied together on the upper part of the surface of the pipeline, while a single tape 25 is used as tapes on both sides of the pipeline through the cavity single rod and then removed from

soil for the immersed end, and this is done in the cavity of the other rod.

A device for immersing in the ground 5 anchor belts operates as follows.

It is preliminarily tuned to the formation of the anchor system with either a ring or a spiral arrangement of tapes in the system. In the first case, the rods 6 and 7 are brought closer to the vertical transverse-plane, and in the second, their cylindrical guides 9 are separated from each other.

15 other along the pipeline axis. In this case, the sliders 21 of the uprights are displaced along the linear guides 20, and the flanges in the flange joints 23 and 24 of the cantilever supports 22 of the cylindrical expressions 9 are rearranged to the required angle. Then, in the cavity of the rod 6, the tape 25 unwound from the drum 26 is passed through and secured at the base of the tip 10, which completes the preparation work. The device is displaced to the pipeline and rests on it with its pillar 4, and then is fixed on it by the claw 5.

Rods 6 and 7 are pressed into the ground by the action of the actuators 8 until the tips 10 and 11 touch each other with their stops 12. This results in the first flashing of the tape with 25 teeth 16 of the fork 15 of the tip 11 in 35 clearances 14 of the groove 13 of the tip 10. A short stroke is performed for removing the rod 7 having a fork tip 10. When the pins 17 of this tip fall into the cavity of the crankshaft 13 of the other tip, they fall out of the grooves 18 of the teeth 16 under their own weight and rotate downward on the hinge pins 19 within the limits beforehand The boundaries are 5 times the angle of rotation. As a result, with an additional short stroke of the rod 7 with a fork-borodkovyy 10 barbs, the tape is secondly pierced with 50 holes in it, located below the holes formed by the teeth 16 during the first piercing. The strip of tape between the holes of the first and second firmware is pinched between

55 frontal surfaces of the teeth 16 and the bead 17 and allows the end of the tape to be removed from the ground when the rod 7 is removed from it.

The removed end of the tape is fastened at the watering trench ascent
