Protection barrier

Abstract

A protection barrier includes a base, the base having a great lower side and a small topside; the base expanding from the topside to the lower side gradually; each of two lateral sides of the base being installed with a first buffer for buffering and resisting impacts from vehicles. The base has an approximate triangle shape with each apex being frustrated. Each of the two lateral sides of the base having a second buffer. A ground anchor is installed to a bottom of the base. The buffers have a shape selected from semi-round shapes, semi-elliptical shapes, and other cambered shapes. The protection barriers can be arranged longitudinally between two lanes for isolation or aside a lane for preventing a vehicle to run out of the lane.

1 . A protection barrier including a base, the base having a great lower side and a small topside; the base expanding from the topside to the lower side gradually; each of two lateral sides of the base being installed with a first buffer for buffering and resisting impacts from vehicles. 
     
     
         2 . The protection barrier as claimed in  claim 1 , wherein the base has an approximate triangle shape with each apex being frustrated. 
     
     
         3 . The protection gird as claimed in  claim 1 , wherein each of the two lateral sides of the base having a second buffer. 
     
     
         4 . The protection barrier as claimed in  claim 1 , wherein a ground anchor is installed to a bottom of the base. 
     
     
         5 . The protection barrier as claimed in  claim 1 , wherein the first buffer is a rubber ring. 
     
     
         6 . The protection barrier as claimed in  claim 1 , wherein the second buffer is a rubber ring. 
     
     
         7 . The protection barrier as claimed in  claim 1 , wherein the first buffer has a shape selected from semi-round shapes, semi-elliptical shapes, and other cambered shapes.
