Abstract
A barrier section for separating the center of a two-way roadway is disclosed herein including a thickened foot portion embedded in the ground with an integrally formed upstanding rail portion rising vertically above the surface of the ground. The foot portion is provided with an open-ended conduit or duct and passageways are provided at an angle leading from the ground surface to the duct in a downwardly converging arrangement. Both barrier portions include steel rod reinforcement extending longitudinally and transversely with respect to the duct. Interlocking devices are carried on opposite ends of the barrier for mating with and interconnecting with additional adjacent barrier sections.
Claims7
A barrier comprising:
- a barrier having a thickened foot portion buried in ground supporting pavement for a roadway, an upstanding portion projecting above the surface of said pavement, and a tapered intermediate portion integrally interconnecting said foot portion to said upstanding portion;
- said foot portion provided with an open-ended duct below said pavement and at least one passageway connecting the surface of said pavement to said duct whereby said duct is in communication exteriorly of said foot portion;
- and
- a second open-ended duct provided in said intermediate portion in fixed parallel relationship with respect to said first mentioned duct.
A positive barrier for blocking passage of a vehicle separating lanes on a roadway comprising:
- a unitary, integrally constructed barrier having a foot portion buried in a ground supporting pavement for a roadway, a tapered upstanding rail portion projecting above the surface of said pavement, and a tapered intermediate portion integrally interconnecting said foot portion to said upstanding rail portion;
- and
- said foot portion provided with an open-ended duct below said pavement extending longitudinally along the length of said barrier having a central axis lying on a central vertical plane of said upstanding portion and at least a pair of transverse passageways opening from opposite sides of said tapered intermediate portion at substantially pavement level and downwardly converging so as to conduct drainage from the surface of said pavement to said duct via gravity and connecting the surface of said pavement to said duct whereby said duct is in communication exteriorly of said foot portion.
A barrier section forming a section in combination with a plurality of identical sections to provide a continuous and co-extensive barrier separating lanes on a roadway, the combination comprising:
- a barrier section having a thickened foot portion buried in the ground supporting pavement for said roadway, an upstanding portion projecting above the surface of said pavement, and a tapered intermediate portion integrally interconnecting said foot portion to said upstanding portion;
- said foot portion provided with an open-ended duct below said pavement and at least a pair of passageways connecting from the surface of said pavement to said duct whereby said duct is in communication exteriorly of said foot portion;
- reinforcement means embedded in all of said barrier portions for strengthening said barrier section;
- guide and interlocking means carried on opposite ends of said barrier sections for matingly interconnecting the opposing ends of adjacent barrier section so as to provide a co-extensive relationship;
- and
- a second open-ended duct provided in said intermediate portion in fixed parallel relationship with respect to said first mentioned duct.
