Fencing of roads

 

(57) Abstract:

The invention relates to the arrangement of roads. The enclosure contains a three-beam blocks, placed at intervals and connected through the holes at the ends of each beam. Equipped with upper and lower ring elements placed rotatably on the flexible connections passing through holes in the blocks. The diameter of the lower ring elements larger than the diameter of the upper ring elements. In the holes of the lower ring elements a flexible connection passes through sections of pipe located ends in the holes of the blocks. The blocks are made with a curved surface pear shaped. Aimed at improving energobaltia and reliability. 6 Il.

The invention relates to the construction and rehabilitation of roads and is intended for use on roadsides and separating lines to avoid crossing the dividing strip in the oncoming traffic.

You know the fence parapet type, containing blocks with a concave side surface and installed flush with the end faces to each other along the edge of the road (see ed.St. USSR N 1712524, CL E 01 F 15/00, 1992).

It is also known fencing of roads containing the curb, the surface of which is at some distance from each other is fixed rotating lugs in the form of rollers (see ed.St. USSR N 1569362, CL E 01 F 15/00, 1990).

A disadvantage of the known technical solution is that the mechanism of rotation of the rollers is made difficult and time-consuming, with negative temperatures and contamination of roadside rotating elements zakladivaetsa and fail. In addition, the fence is no duty cycle, which beside him linger exhaust fumes, dirt, snow, etc.

The closest analogue, as to the technical essence and purpose, is taken as a prototype fencing of roads, containing three-beam blocks, which are placed at intervals and the well-known fencing is that when hit by such a fence inevitable deformation of the vehicle. Besides the shape of three-prong unit does not provide sufficient strength to the fence.

An object of the invention is the implementation of safe motion correction of the vehicle hit a fence while providing the necessary strength of the fence.

The technical problem is solved by the fact that well-known fencing of roads, containing three-beam blocks, placed at intervals and connected through the holes at the ends of each beam, according to the invention is equipped with upper and lower ring elements placed rotatably on the flexible connections passing through holes in the blocks, the diameter of the lower ring elements larger than the diameter of the upper annular elements in the holes of the lower ring elements a flexible connection passes through sections of pipe located ends in the holes of the blocks, the latter is made with a curved surface pear-shaped.

Hitting the fence due to the rotation of the lower ring elements traffic smoothly adjusted in a safe napravleniya the shock kinetic energy transport is extinguished due to friction and connection to the work of all units of the fence. When the fence is bent in plan, forming different configurations, while maintaining its integrity, and creates an effective braking force.

The invention is illustrated features. In Fig. 1 shows the enclosure, General view (fašade) of Fig. 2 is a view in plan; Fig. 3 is a cross section along a-a in Fig. 1; Fig. 4 - upper annular element with a rope; Fig. 5 - lower annular element with pipe and cable; Fig 6 is a diagram of the locations of pipes, wire rope through the lower annular element (section).

The enclosure includes spaced intervals between a three-beam blocks 1 with a curved surface pear shaped. The blocks 1 are interconnected via a flexible connection in the form of a cable 2, which passes through holes 3 in the boxes 1, made at the ends of each beam. The device is equipped with upper and lower elements 4 and 5, respectively. The annular elements 4 and 5 are rotatably on the cable 2, and the diameter of the lower annular element 4 is larger than the diameter of the upper annular element 5. The holes 6 of the lower ring elements 4 a flexible connection in the form of a cable 2 passes through the pipe pieces 7, which are located in holes 3 blocks 1.

The guard operates as ablement 4, rotation which returns the vehicle to the side of the road. If the front wheels of the vehicle moves through the annular elements 4, the damping of the kinetic energy will be curved lateral surface pear shaped blocks 1. Further work will be connected through the cable 2 all blocks 1 fencing, reflecting the weight of the vehicle and adjusting its movement in a safe direction. In addition, the interval between the flat blocks 1 pear shape allows to dissipate accumulated in the springs of the vehicle energy, which increases the braking effect of the vehicle. Side curved surface-shaped block 1, approaching the shape of a triangle, increases the stability and durability of the fence as a whole.

Fencing of roads, containing three-beam blocks, placed at intervals and connected through the holes at the ends of each beam, characterized in that it is provided with upper and lower ring elements placed rotatably on the flexible connections passing through holes in the blocks, the diameter of the lower ring elements larger than the diameter of the upper ring elements, oversh blocks, the latter is made with a curved surface pear shaped.
