Abstract
A safety barrier for roads, used as a traffic divider, includes a double row of concrete made New Jersey barrier elements which allow the realization of a hedge on earth interposed between the barrier elements. The earth is contained in a sack made of nonwoven fabric, fixed, to both barrier elements, so as to leave gaps behind the rear walls of the barrier elements. The gaps together with a plurality of sliders or runners provided on the barrier's base, allow during impact a controlled displacement of the barrier elements. The calibration of decelerations is adjusted by the material used for the sliders.
Claims20
A safety barrier for roads, forming a traffic divider, comprising:
- two rows of modular elements made of concrete;
- and
- an amount of earth which is interposed between said concrete made elements, wherein
- said amount of earth is contained inside a receptacle laid on an embankment, and
- said receptacle extends along a whole length of one of said concrete made elements and leaves two gaps between the receptacle and a rear wall of the concrete made elements,
- said concrete made elements have on a lower surface a plurality of sliders allowing a calibration of a deceleration of a vehicle during a first period of an impact, that is until one of the concrete made elements abuts the receptacle.
A safety barrier for a road, forming a traffic divider comprising:
- two rows of modular concrete elements;
- and
- a receptacle containing earth being interposed between said modular concrete elements and contacting an embankment of the road,
- said receptacle extending along an entirety of the first and second modular concrete elements, and leaving first and second gaps between said receptacle and a rear wall of the first and second barrier elements,
- said first and second barriers including a lower surface having a plurality of sliders,
- said plural sliders being structured and arranged to decelerate a vehicle during a first period of an impact, prior to when one of said first and second modular concrete elements abuts said receptacle, wherein
- said receptacle is a sack of non-woven fabric having an external cover and is reinforced by a material that allows water to pass.
A safety barrier for a roadway, comprising:
- first and second modular self-supported concrete barriers;
- a receptacle containing earth being between said barriers and contacting an embankment of the roadway, said receptacle extending longitudinally along a length of the barriers;
- first and second gaps being between the receptacle and the first and second barriers, respectively, said first and second gaps extending longitudinally along the length of the first and second barriers and along an entirety of a height of the receptacle,
- said first and second barriers being movable, independent from the receptacle, from a first position apart from the receptacle to a second position contacting the receptacle.
