In particular, it can be used in the restoration and construction of bridges on military roads to hold traction and brake winches when sliding the spans of road collapsible bridges (AWP). PM's technical task is to develop a temporary screw-screw anchor design with a crossbar for retention of traction and brake winches when sliding superstructures of road collapsible bridges in flooded soils. The specified technical problem is solved due to the fact that the temporary pile screw the howl anchor with the crossbar stops consists of a SARM-M time sheet screw pile and a tubular crossbar fixed from the screw pile extension perpendicular to it with a nut and bolt, characterized in that the screw pile extension is partially located in the ground and two metal anchor piles are immersed in front of it and the anchor sling of the winch is fixed to the service screw pile in such a way as to additionally create an effort to push the screw pile extension into the ground.

Description

A utility model (hereinafter referred to as PM) relates to the field of bridge building. It, in particular, can be used in the restoration and construction of bridges on military roads to hold traction and brake winches when sliding the spans of road collapsible bridges (AWP).

A known construction of a wood-earth anchor used to secure traction, brake and brace winches of an average road collapsible bridge (SARM-M) [1, p. 97]. This design of wood-earth anchor is taken as a prototype PM.

The main disadvantages of the prototype are:

high costs of material and manual labor on the device;

low pace of the device;

inability to reuse;

the complexity of the device, especially in flooded soils.

The technical task of PM is to develop the design of a temporary pile-screw anchor with a crossbar (WELD) for holding traction and brake winches when sliding overhead spans in flooded soils.

The specified technical problem is solved due to the fact that the temporary pile screw anchor with a bolt stop consists of a SARM-M time sheet screw and a bolt with a tubular bolt nut fixed from the screw pile extension perpendicular to it, characterized in that the screw pile extension is partially is placed in the ground and two metal anchor piles are immersed in front of it, and the winch anchor line is fixed to the service screw pile in such a way as to additionally create an effort to push the extension into Intovoy piles into the ground.

The proposed PM design and its elements are shown in the figure, where it is indicated:

FIG. 1 - view of the anchor on the facade; FIG. 2 - side view of the anchor; FIG. 3 is a top view of the anchor;

pos. 1 - personnel screw pile;

pos. 2 - extension of the screw pile;

pos. 3 - a bolt with a nut;

pos. 4 - anchor pile;

pos. 5 - anchor sling of the winch;

pos. 6 - traction winch.

PM is made on site in the following sequence. At a selected location for the SVARU device, using a standard installation of screwing piles (UZS), a personnel sheet screw pile 1 is vertically immersed (Fig. 1). Perpendicular to it, the screw pile 2 extension is partially dug into the ground. The connection of the screw pile 1 and the screw pile 2 is connected by a bolt with a nut 3. In addition, the screw pile 2 is additionally fixed by two anchor piles 4 that are clogged into the ground and are equally distant from time sheet piles 1 (Fig. 1, 3). The loop fastening of the anchor sling 5 of the winch 6 is carried out on the trunk of the service screw pile 1 on top of the screw pile 2 extension for the bolt with nut 3 (Fig. 2, 3).

PM works as follows. When the winch cable 6 is pulled to the bridge span, the sling 5 is tensioned. As a result, the extension of the screw pile 2 is pressed by the rope 5 to the ground, preventing the horizontal movement of the service screw pile 1. Anchor piles 4 in turn prevent the extension of the screw pile 2, thereby increasing the resistance of the screw pile 1 to horizontal displacement from the tension of the sling 5. This ensures the stability of the traction winch 6 involved in the slide of the bridge span. The number of anchors as well as traction and brake winches is determined by calculation.

Thus, the proposed PM allows you to increase the assembly rate of road collapsible bridges up to 10%. Also, this design can be used when securing and holding floating bridges, pile loading and other ferries at high flow speeds, on flooded shores and floodplains.
