Description

The proposed device relates to the field of construction and arrangement of roads and is intended primarily for the protection on both sides of pedestrians and technical means of organizing traffic from a frontal impact of vehicles at crossings.

Known devices for protecting crossings and technical means of organizing traffic from vehicles (RF certificates No. 2.000.376, 2.024.668, 2.055.967, 2.059.915, 2.066.410, 2.085.654, 2.085.655, 2.135.675, 2.186.281, 2.168.581, 2.193.085, 2.200.788; US patents No. 3,540.699, 3.841.775, 4.653.954; UK patent No. 1,172,460; German patent No. 3,612.292; Stratov A.E ., Fishelson MS City movement. - M .: Publishing house of building literature, 1965, p. 68, fig. 40 and others).

Of the known devices, the closest to the proposed one is the "Road Buffer" (RF patent No. 2.193.085, E 01 F 13/00, 2000), which is selected as the base object.

The hollow body of the specified buffer is made of plastic, for example polyethylene, and has a base, upper surface and four walls. The front and rear walls are convex, and the flat side walls are parallel to each other. The front wall has a cylindrical shape. The rear wall is made with a radius of curvature, a large radius of curvature of the front wall, and is equipped with attachment points for connecting with mating nodes of the mating sections if necessary. The upper surface has three sections. A flat horizontal section is located from the plane of articulation of the front wall with the side walls towards the rear wall. From the horizontal section back and forth two sloping downward flat sections. The inclination of the anterior portion is 15 ° ± 10 ° from the horizon of the plane, and the inclination of the posterior portion is 55 ° ± 30 ° from the horizontal plane.

However, the well-known buffer can only reduce the degree of damage to the car, the severity of injuries to the driver and passengers, minimizing fatalities, and also improve the safety of repair work by providing a high degree of damping of the front or oblique frontal impact of the car.

The objective of the invention is to expand the functionality of the buffer by ensuring the safety of pedestrians on both sides of the frontal or oblique frontal impact of the car at the crossings.

The problem is solved in accordance with the present invention in that the islet of safety is road, comprising, in accordance with the closest analogue, a road buffer containing a hollow body formed by a base, upper surface, front and rear walls and filled with ballast, which is sand or water or an aqueous-salt solution with a volume of at least 600 l, while the front wall has a convex cylindrical shape and is made with three recesses, each of which has an opening for a fixing element enta, one of the recesses is located on the plane of symmetry of the body, and the other two are symmetrically relative to this plane, the back wall is made with a similar recess with holes located on the plane of symmetry of the body, the base is made flat with two pairs of grooves symmetrical with respect to the plane of symmetry of the case with walls perpendicular to the base, the grooves are directed towards each other from the front and rear walls and are designed to connect with anchors, differs from the closest analogue in that it is equipped with the second buffer of the road, the platform and the technical means of organizing traffic, and the upper surface of the buffer body is made horizontal with a hole closed by a plug, the rear wall of the buffer body is made vertical, while the buffer body is made of polyethylene, or plastic, or rubber, and the platform is made of two sections connected by pins, each section has a platform and a power buffer located at the end of the platform and equipped with attachment points on the outside for connection with the rear wall Coy buffer traffic, the site with the outside power buffers are provided for connection with anchors grooved housing road buffers pads formed between the pedestrian area force the buffers to which the anti-slip coating applied on the power buffers has technical means of traffic.

At the same time, the platform is made of rubber with a metal frame, and traffic lights or traffic signs based on ABS plastic are used as technical means for organizing traffic.

The housing of road buffers is made of polyethylene, plastic or rubber, which, first of all, provides a high degree of damping of the impact force in the event of a vehicle colliding with a buffer due to the formation of a box-like structure with a more pliable front wall. The combination of a cylindrical front wall of the buffer, which, when deformed, extinguishes the kinetic energy of the vehicle, and a rigid power buffer of the platform, can significantly ensure the safety of pedestrians in the pedestrian zone.

In addition, the use of, for example, rubber significantly reduces injuries to the driver, passengers and pedestrians.

Filling the buffer cavity with cheap ballast (sand, water or a water-salt solution) significantly increases their mass, which, in combination with the form of the casing described above, can successfully suppress even frontal impacts of a moving car.

The execution of the housing of the buffers made of polyethylene, plastic or rubber, and the platform of rubber with a metal frame makes the production of an island of safety technological and cheap.

Polyurethane coatings or rubberized mats are used as anti-slip coatings, which also increases the safety of pedestrians and makes their stay in the pedestrian zone comfortable and quiet.

The use of technical means of traffic management, installed in the places of transition on the racks of the platform, increases the safety of vehicles and pedestrians.

The proposed road safety island is illustrated by drawings, in which Fig. 1 is a general view of the road safety island, in Fig. 2 is a side view of the road safety island, in Fig. 3 is a section along AA of Fig. 2 (fragment) and in .4 - bottom view of the buffer.

Road safety island contains buffers 1, platform 2 and technical means 3 of traffic organization.

Each buffer 1 is formed by a hollow body 4 and is made of polyethylene for rotational molding, light-stabilized to ultraviolet radiation, or plastic with the corresponding properties, or rubber with the corresponding properties. The housing 4 consists of a base 5, an upper surface 6, a front 7 and a rear 8 walls.

The front wall 7 has a convex cylindrical shape, the upper surface 6 is horizontal and the rear wall 8 is vertical. On the horizontal surface 6, a hole is made, closed by a plug 10.

The base 5 of the housing 4 is made flat with two pairs of grooves symmetrical relative to the plane of symmetry of the housing 11. The groove walls are perpendicular to the base 5, while the grooves 11 are directed towards each other from the front 7 and rear 8 walls and are designed to connect with anchors installed on platforms (not shown).

The front cylindrical wall 7 is also made with three recesses 9, each of which has an opening 12 for a fastening element (not shown) that provides connection with the platform platform 2. One of the recesses is located on the plane of symmetry of the body, and the other two are symmetrically relative to this the plane.

In addition, the flat rear wall 8 is also made with a similar recess with a hole for fasteners located on the plane of symmetry of the housing.

The cavity of the housing 4 is filled with ballast, while the volume of the ballast must be at least 600 l. The ballast used is water or a salt-water solution (in summer) or sand (in winter). Ballast is poured (filled) through the hole in the housing, then the hole is closed by a lid 10.

The platform 2 is made of two sections connected by pins 13. Each section has a platform 14 and a power buffer 15 located at the end of the platform and equipped with attachment nodes (not shown) on the outside for connecting to the rear wall 8 of the road buffer. Platforms 14 on the outside of the power buffers 15 are equipped with anchors (not shown) for connection with the grooves of the base 5.

The platforms 14 between the power buffers 15 formed a pedestrian zone 16, which is applied anti-slip coating 17, which is used as polyurethane or rubberized mats.

Traffic lights and traffic signs mounted on racks were used as technical means for organizing traffic.

Transport and pedestrian LEDs are based on LED modules. Housing and diffuser made of impact resistant polymer materials.

The economic efficiency of LED traffic lights is high due to its durability and low power consumption. Traffic lights based on LED modules provide a high brightness significantly higher than lamp, while consuming energy 4 times less.

Road signs based on ABS plastic are two plastic surfaces with images (masks) of signs connected to them by interconnected foam PVC.

Such signs have a number of significant advantages:

1. Not subject to corrosion. The base of the mark has an almost unlimited service life.

2. High impact resistance. ABS plastic withstands significant impact and static loads without collapsing and without permanent deformation.

3. A wide temperature range of use (from -45 ° С to + 45 ° С), allowing the use of signs in almost any climatic zone.

4. Safety in case of collision and collisions.

5. The ability to apply the image (mask) of the sign from two sides.

Thus, the proposed road safety islet in comparison with the base object provides pedestrian safety and protection of traffic management equipment (traffic lights, road signs, etc.) from two sides from the frontal and oblique frontal impact of the car at the crossings.

The road safety island is made in the form of a ready-made design, it is characterized by mobility and can be temporarily used in hazardous areas of the road, quickly installed and dismantled.

Thus, the functionality of the base object is expanded.

The proposed safety island was developed by specialists of the Stroy Invest Project construction organization, successfully passed tests on the ring motorway around St. Petersburg, received approval from the government of St. Petersburg and the traffic police and can be widely used on Russian federal highways.
