2, A device for erecting a ground anchor, including a frame and a barrel immersion mechanism installed on it, characterized in that, in order to reduce the labor intensity of the work, the barrel immersion mechanism is mounted on the frame with the possibility of turning into a vertical I

The invention relates to the field of construction, in particular to the construction of ground anchors for mainly linear structures, such as pipelines.

The purpose of the invention is to reduce the labor intensity of the work.

On. FIG. 1 schematically shows the device in the working position, side view; in fig. 2 - the same, in the initial position; in fig. 3 - A-A in FIG. 2; in fig. 4 - anchor shaft, general view; in fig. 5 - pl: ita anchor, general view.

The method of erecting a ground anchor includes immersion into the ground by pressing in the barrel 1 with the fifth of the two; plates 2 and 3 to the design elevation: ets and penetration into the ground from the surface along a curved trajectory of the plate 4, bent in an arc and having a slot 5 oriented E1da11b of the direction of movement of the plate perpendicular to it forming, and plate 4 going into the ground before placing it plates 2, 3 and stop the end of the slot in the bar 1.

A device for implementing the method of erection of a ground anchor consists of a guide rag "1X 6 with supports 7 and installed: on the frame 6 of the mechanism 8 for loading the barrel of the anchor 1 and the mechanism 9 of the dowel shafts 4. The mechanism 8 consists of a hydraulic cylinder 10 with a clip 11, rigidly fixed at the end of the hollow

13

It is provided with a curvilinear rod placed in this plane, the concave surface of which faces the power cylinder, one end of which is rigidly attached to the barrel immersion mechanism, the other is made to grip under the anchor plate.

hydraulic rod 12 through passage. The mechanism 9 consists of a curved rod 13 curved along an arc of a circle and rigidly connected to a lever

14 pivotally mounted on the frame 6 and having a drive in the form of a hydraulic cylinder 15 pivotally connected to the frame 6 and the lever 14. At the end of the rod 13 a gripping plate 16 is placed

4. The hydraulic cylinder 10 by the brackets 17 is fixed on the lever 14. The rod 12 and the rod 13 are located in the same plane.

The device is rigidly suspended

on the boom of a hydraulic excavator (not shown in the drawing) with the connection of the excavator's hydraulic systems and the device. The barrel of the anchor 1 is installed in the cavity of the rod 12 of the hydraulic cylinder 10 up to the stop with the grooves 3 in the nodes of the clamp 11 and fixed in it. The plates are installed in the grippers 16 so that the axis of the rod and the slot. The plates are in the same vertical position. The hydrodiline 15 lever 14 is moved to the vertical position, press into the predetermined depth of the rod 15, then press the anchor plates 4 until the plate end faces

in the rod.

The technical and economic effect is due to the anchoring of the trunk in the soil of a not disturbed structure and in reducing the types of mechanisms used for

construction of a ground anchor, in particular, in the construction of pipelines.
