RU191230U1 - Flexible concrete slab with soil anchor - Google Patents

Abstract

The utility model relates to the construction of protection to prevent the negative impact of water on slopes, including slopes of roads, banks of reservoirs, foundations of bridges, dams, dams and other objects. A flexible concrete slab (hereinafter referred to as the GB slab) is securely held on an inclined surface to be protected using a soil anchor (key 9), the design of which provides a stabilizer (key 6).

Description

The utility model relates to the construction of protection to prevent the negative impact of water on slopes, including slopes of roads, banks of reservoirs, foundations of bridges, dams, dams and other objects.

A flexible concrete slab (AC 251463) (hereinafter referred to as the GB slab) with a soil anchor is a set of concrete blocks (Fig. 1 position 1), interconnected by a flexible connection (Fig. 1 position 2), mounted on a slope (Fig. 1 position 3) using a soil anchor (patent No. 132094) (Fig. 1 position 4). GB-plates are fastened with a soil anchor by welding using metal embedded parts on peripheral concrete blocks (patent No. 2503773) (Fig. 1 position 5). When using GB-plates (as well as when using other flexible protective coatings) it is unacceptable to use the bottom stop. Based on this, the soil anchor is an integral part of GB-plates when used on inclined surfaces.

A drawback of an existing GB slab with a soil anchor is its slope drift (sliding) under the influence of gravity without breaking away from the surface to be protected. The GB plate drifting down the slope acts on the soil anchor. Under the influence of the forces acting on the soil anchor, the upper part of the soil anchor, cutting through the soil, is displaced after the drifting GB plate towards the foot of the slope, that is, the axis of the soil anchor is shifted.

The objective of this utility model (technical result) is to change the design of GB-slabs with soil anchor so as to exclude (minimize) the drift of GB-slabs down the protected slope.

The technical result (the stated goal) is achieved by introducing into the design of the GB-plate stabilizer soil anchor (Fig. 2 position 6), which is located in the upper part of the rod of the soil anchor.

The soil anchor stabilizer is a metal plate (Fig. 3 position 7) to which a piece of pipe (Fig. 3 position 8) of square section is attached by welding, inside which the rod of the soil anchor (Fig. 2 position 9) passes.

The dimensions of the soil anchor rod (Fig. 2 position 9) and the pipe segment (Fig. 3 position 8) are selected so that the soil anchor rod freely passes through the pipe, but does not have the ability to turn. To do this, the stabilizer pipe section and the soil anchor rod must have a square or other non-circular cross section.

If the rod and the stabilizer pipe will have a circular cross-section, the design should include an additional device that prevents the stabilizer from turning through the rod of the soil anchor, for example, a screw clamp.

The utility model works as follows.

A GB plate is laid on the prepared (leveled and compacted) soil surface. A soil anchor is driven into the soil along the upper edge of the GB plate (Fig. 1, position 4).

At the end of driving the anchor and carrying out activities related to the opening of the paws of the soil anchor (pushing the hammered anchor up a few centimeters), a stabilizer is put on the rod of the soil anchor (Fig. 1, position 6). In this case, the plane of the stabilizer should be perpendicular to the line of possible drift of the GB plate. A stabilizer mounted on the ground anchor rod is driven into the ground and fixed to the ground anchor rod, for example, by welding. The soil anchor with the stabilizer is connected by welding to the metal embedded parts of the concrete blocks of the GB-plate. If there is a gap between the rod of the soil anchor (Fig. 1 position 4) and the metal embedded part (Fig. 1 position 5), the dimensions of which do not allow the anchor to be welded to the metal embedded parts, use an intermediate element (Fig. 1 position 10), one edge which is welded to the metal embedded part, and the other edge is welded to the anchor.
