Description

The device relates to the field of bridge construction and can be used in the restoration of railway bridges, as well as for fixing various structures to the ground.

The prior art known soil anchor with two plates, immersed in the soil, placed one above the other and connected to the system by a cable guy [1]. Also, a known method of installing a soil anchor of this type [2]. The disadvantage of these solutions is the lack of the ability to redirect the pulling force from vertical to horizontal.

At the same time, a device is known for bringing a soil anchor to its working position [3], including: a base plate, anchor grips, a movable cross-arm, a power element, holes in the plate for passing anchor cables. The disadvantages of this device are:

firstly, that it is not combined with the soil anchor into a single system that ensures the formation of a compacted soil core under the slab. As a result, it is possible to flush and tip over the top plate;

secondly, does not protect the soil base of the base plate from erosion.

The objectives of the utility model are to redirect the pulling force from the anchor from a vertical to a horizontal plane, as well as to ensure stability and eliminate erosion.

In FIG. 1-3 show respectively a plan, a longitudinal and a transverse section of the proposed anchor device. The device includes: a bottom plate 7 buried in the ground; the upper base plate 2 installed on the bottom of the open pit 3, a metal frame 4 with a block 5 concreted into it 8 of the plate 1 into the hole of the plate 2 to the block 5 and then to the fixed construction of the floating bridge.

The horizontal force from the floating bridge is redistributed in the form of vertical pressure through block 5, the metal frame 4 and plate 2 to the soil of the bottom of the pit 3, as well as the vertical pulling force from the plate 1 to the upper soil layer. As a result, a compacted soil core is formed under the plate 2.

The stability of the plate 2 from tipping is provided by its location above the plate 1, the protruding console in the direction of the bridge and the combination of plates in a single system with cables 6.

Protection of the soil base under the slab 2 from erosion is provided by the passage of the pit 3. When the water rises, the pit will be flooded and brought in by soil sediments that impede erosion.

Claims (3)

1. Anchor device for securing floating bridges, including a lower reinforced concrete slab buried in the ground, an upper reinforced concrete slab, holes in the slab, anchor cables, characterized in that the upper base slab is installed in an open pit, filled with river sediment when the water level rises. 2. The device of the slab according to claim 1, characterized in that the slabs are equipped with embedded devices for attaching anchor cables and are combined into a single system. 3. The device of the plate according to claim 1, characterized in that a metal frame with a block is concreted into the upper base plate, the upper plate being longer than the lower one towards the bridge.
