Vehicle restraint system having a concrete barrier wall

Abstract

The invention relates to a vehicle restraint system having a concrete barrier wall, the concrete barrier wall having at least one through hole. A blind hole that is associated with the at least one through hole is arranged in a supporting surface beneath the at least one through hole, a pin being located both within the at least one through hole and within the blind hole that is associated with the at least one through hole. It is proposed that the pin have a specifiable amount of play relative to the blind hole.

         16 . A vehicle restraint system comprising:
 a concrete barrier wall having at least one through hole, a blind hole associated with the at least one through hole being arranged in a supporting surface beneath the at least one through hole; and   a pin arranged both within the at least one through hole and within the blind hole associated with the at least one through hole;   wherein the pin has a specifiable amount of play relative to the blind hole.   
     
     
         17 . The vehicle restraint system according to  claim 16 , wherein the specifiable amount of play of the pin relative to the blind hole corresponds to at least 5% of the diameter of the pin. 
     
     
         18 . The vehicle restraint system according to  claim 16 , wherein the supporting surface has a bonded base layer beneath the at least one through hole. 
     
     
         19 . The vehicle restraint system according to  claim 18 , wherein the blind hole that is associated with at least one through hole penetrates the bonded base layer. 
     
     
         20 . The vehicle restraint system accordi according to  claim 16 , wherein the pin has a diameter of at least 1.5 cm. 
     
     
         21 . The vehicle restraint system according to  claim 16 , wherein the pin is headless. 
     
     
         22 . The vehicle restraint system according to  claim 16 , wherein the upper end of the pin is arranged within the at least one through hole. 
     
     
         23 . The vehicle restraint system according to  claim 16 , wherein the pin has a depth in the supporting surface of no more than 60 cm. 
     
     
         24 . The vehicle restraint system accord according to  claim 16 , wherein the pin has a fluting. 
     
     
         25 . The vehicle restraint system according to  claim 16 , wherein the pin is made of a reinforcing steel. 
     
     
         26 . The vehicle restraint system according to  claim 16 , wherein at least one of the at least one through hole and the blind hole has a seal. 
     
     
         27 . The vehicle restraint system acc according to  claim 16 , wherein the at least one through hole and the blind hole that is associated with the at least one through hole are arranged on only a first side of the concrete barrier wall. 
     
     
         28 . The vehicle restraint system according to  claim 27 , wherein the first side of the concrete barrier wall is arranged so as to face away from a roadway when the concrete barrier wall is in an installed state. 
     
     
         29 . A method for constructing a vehicle restraint system, comprising:
 drilling a blind hole in a supporting surface beneath at least one through hole, the at least one through hole being in a concrete barrier wall of the vehicle restraint system, the blind hole being associated with the at least one through hole;   arranging a pin being both within the at least one through hole and within the blind hole associated with the at least one through hole; and   selecting a diameter of the blind hole so that the pin has a specifiable amount of play relative to the blind hole.   
     
     
         30 . The method according to  claim 29 , wherein the blind hole associated with at least one through hole is drilled through the at least one through hole into the supporting surface.
