Abstract

This invention relates to making ground anchors. The purpose of the invention is to increase the carrying capacity of the anchor. Anchor consists of a body and anchor elements. The body is made in the form of two parallel plates 1 interconnected by a jumper 2 and having grooves 3 along the contour. The anchoring elements are made in the form of elastic bands 4 placed in the grooves of the plates and attached to the rectangular nut 5 by their upper ends 5. rod 6. 5 Il.

Description

The invention relates to the construction and implementation of soil anchors used to fasten various structures to the soil.

The purpose of the invention is to increase the carrying capacity of the anchor.

FIG. 1 shows a ground anchor, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a view of B in FIG. one; in fig. 5 shows the node I in FIG. one.

Ground anchor includes body and anchor elements. The body is made of two parallel plates 1, united by a bridge 2, which is located along the axis of the body and in the upper part is made of a two-wall, box section. Plates 1 in the lower part are made wider. Along the contour of the plates, grooves 3, curved in the lower part and straight in the top, are made. Anchoring elements made in the form of elastic flexible tapes A are inserted into the grooves of the plates with the possibility of their movement. The leading end of the elastic bands is made beveled. The belts are moved by an extension mechanism consisting of the upper part of the rectangular threaded nut 5 webbing hub and interacting with it along the thread of the screw rod 6. The threaded nut 5 is rigidly connected with the upper ends of the elastic ribbons. The screw rod 6 is rigidly connected to a bar, made in the form of a column of screwed rods 8.

The anchor is brought into position as follows.

At the specified level of the soil, the body is crushed by the expanding column when the threaded nut 5 is in the upper position. At the diving level, the pressure is stopped and the rod string 8 is rotated together with the screw rod 6, which moves the threaded nut 5 and advances the jumper 2 flat metal tapes, forcing them to move along the grooves 3, as along the guides along the perimeter of the plates 1, simultaneously cutting out a block of soil placed between the plates 1 and the lintel

2, along a closed contour until the leading cutting edges of the strips at the lower end of the plates 1 come into contact with jumper 2. A predetermined pulling force is applied to the column of rods 8.

Claims (1)

The carrying capacity of the anchor is increased by using the weight of the soil block cut out of the array, the dimensions of which are determined by the longitudinal dimensions of the hull, which for weak soils can be significantly increased. Claims of invention the body and the opposite grooves of the other wall, and anchoring elements mounted in the opposite grooves with the possibility of movement, characterized in that In order to increase the carrying capacity of the anchor, the grooves of each wall are formed on the side facing the other wall and made with their lower ends, each anchor element is designed as an elastic band with a leading edge beveled out, and the upper part of the jumper is made of two-sided fields Equipped with a mechanism for extending anchor elements made in the form of the rod, and interacting with it through the thread of the nut installed between the walls of the upper part of the jumper and rigidly connected with the upper ends of the elastic bands. ° bU fig.Z 77 /// HL VV Budff eight FIG 5
