Barrier with internal drainage duct

Claim 2

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.

Claim 3

The invention as defined in claim 1 including interlocking means comprising a pair of elements outwardly projecting from one end of said barrier and a pair of depressions provided in the other end of said barrier.

Claim 4

The invention as defined in claim 2 including guide means comprising tapering each of said elements and conforming said depressions to align and receive said tapered elements.

Claim 5

The invention as defined in claim 3 wherein said passageways are open from opposite sides of said barrier and downwardly converge to as to conduct drainage from the surface of said pavement to said first mentioned duct via gravity.

Claim 6

The invention as defined in claim 4 including an additional pair of passageways provided at the other end of said barrier.

Claim 7

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.

Claim 8

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.

Claim 9

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.

Claim 10

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.
