RU-2861341-C1 - COMPOSITE ROAD REINFORCED CONCRETE BARRIER (VARIANTS)

Abstract

FIELD: road marking. SUBSTANCE: invention relates to means for ensuring road traffic safety. A composite road reinforced concrete barrier consists of at least two building blocks installed one after another in length, made in the form of an isosceles or non-isosceles trapezoid widening towards the base, each of which is provided with blind holes turning into through holes, and grooves located on the end faces of the building blocks. The blocks are connected to each other in length by means of hinges or steel shaped profiles with a locking connection, extending from the building blocks, and connecting shaped profiles located in the grooves, as well as to the road pavement base by means of radius-bent studs, one end of which is located in the lower part of the building block and has anchorage in it. The other end is brought out through the upper plane of the building block and passed through a through hole in the building block with subsequent tightening to an embedded part through a set of washers and nuts. In a variant of the road barrier, additionally each building block contains through longitudinal sleeves for passing cables or ropes, located longitudinally along the centre of the section, through which cables or ropes pass, containing at the ends anchor devices in the form of anchor plates fixed by anchor bolts on concrete foundations. Hollow posts are installed between the end building block and the anchor devices. EFFECT: increased speed of installation or replacement of existing barrier fences. 19 cl, 8 dwg

Description

Field of technology The invention relates to means for ensuring road safety on motorways and artificial structures, as well as highways, with the prevention of emergency situations without driving into the oncoming traffic lane. State of the art In today's world, the intensity and speed of traffic are increasing. Engineers are inventing new, more powerful and faster vehicles every day. Due to increased traffic, the number of road accidents is also increasing. One of the most serious consequences of an accident is driving into oncoming traffic. Abroad, the intensive use of road safety barriers began in the 1930s, when the first reinforced concrete structures, as well as metal profiles and cable (with slack cables), were developed and tested. In Russia, the intensive introduction of road safety barriers began in the 1970s and 1980s. The estimated speed of vehicles hitting such barriers at that time was 40-60 km/h. Currently, ever faster cars are appearing on the roads, and despite the increase in traffic intensity over the last 5 years by more than 15%, the accident rate and severity of road traffic accidents have not decreased. The closest technical solution to the first version of the invention is a building block for filling gaps in a road barrier (RU 66757, IPC E04B 2/14, published 09.27.2007), which contains ends, a bottom side and longitudinal side sides of unequal length, each of which is a cylindrical surface, close in shape and size to the side surface of the road barrier and perpendicular to at least one end, while the other end has a projection limited by a vertical curved surface connecting the longitudinal side sides. This technical solution has a number of disadvantages, namely: - there are no fastening elements to the road surface, which prevents the block from being held in place when a vehicle collides with it; - there are no elements for fastening the blocks together along their length, which does not allow the integrity of the group of blocks to be maintained between themselves in the event of an accident. The closest technical solution to the second variant of the invention is a cable road barrier (RU 126014, IPC E01F 15/02, published 20.03.2013), consisting of anchor devices in the form of anchor plates located along the line of the barrier, secured with anchor bolts on narrow concrete foundations installed in the ground, steel cables with turnbuckles and end couplings for fastening the cables to the anchor plates, profile posts with grooves for placing cables in them, installed in steel sleeves concreted into foundation blocks installed in the ground along the road, wherein the profile posts are installed in a staggered order relative to the cables, are made hollow and have horizontal grooves in each of which a cable is placed, fixed from falling out of the grooves by a vertical insert installed inside the hollow post, between the cables and the wall in the groove area, when For this purpose, a separate anchor plate is made for each cable. A drawback of the existing device is that the posts remain tilted or bent after an accident, leading to the risk of further accidents. Damaged posts are often not replaced for a long time, reducing the barrier's holding power. The use of cables at night and on unlit roadways creates areas with poor visibility, potentially leading to a vehicle striking the barrier, causing an accident. The barrier's design ensures that contact with the cable section of the barrier itself "pulls" the vehicle in, preventing it from changing its trajectory, which can further aggravate the accident. Disclosure of invention The technical result of the claimed embodiments of the invention consists in increasing the speed of installation or replacement of existing barrier fences, reducing the risk of accidents on dangerous sections of roads with high traffic intensity, increasing the energy capacity of barrier fences, and reducing the severity of the consequences of road accidents. The technical result of the first embodiment of the invention is achieved in that the composite reinforced concrete road barrier consists of at least two building blocks (1) installed one after the other along the length, made in the form of an equal-sided or unequal-sided trapezoid, expanding towards the base, on each of which blind openings (2) are provided, turning into through openings (3), and grooves (4) located on the end faces of the building blocks (1), wherein the building blocks (1) are connected to each other along the length by means of connecting loops (5) or steel shaped profiles with a locking connection (6), coming out of the building blocks (1), and connecting shaped profiles (7) located in the grooves (4), as well as with the base of the roadway, by means of studs (8) bent along the radius, one end of which is located in the lower part of the building block (1) and has an anchorage in it, and the other end is brought out through the upper plane of the building block (1) and passed
