Traffic barrier and method of construction
First Claim
1. A traffic barrier for use adjacent a roadway having an exposed horizontal top surface of a retaining wall, comprising:
- a. a barrier formed of at least one similar, end aligned barrier segments, each of said barrier segments including;
i. a traffic facing sidewall having a longitudinal slot defined by a pair of legs;
ii. a longitudinal channel along a nether face; and
iii. a second and opposite sidewall;
b. a cooperative exposed top surface of said retaining wall facially engaging said barrier by lengthwise contact thereagainst in a stacked relationship;
c. spaced first eyelet means supported by said barrier;
d. spaced second eyelet means supported by said retaining wall;
e. said first and second eyelet means aligning cooperatively and forming an oval locking relationship with said barrier and said top surface of said retaining wall;
f. an elongate rod serially threaded through all of said eyelet means; and
g. cast-in-place concrete filling said longitudinal channel and said longitudinal slot.

Abstract
This invention relates to a pre-cast concrete traffic barrier element and a method of constructing a traffic barrier using the element on a vertical face of a retaining wall. The barrier element is a profiled reinforced block of concrete having a bottom surface with a longitudinally extending channel therein. The traffic barrier element is supported on the retaining wall with a top surface of the retaining wall being received within the channel. U-shaped anchoring bars project from an interior portion of the traffic barrier element and from the top surface of the retaining wall to form an oval keyway the length of the longitudinal channel. A locking bar arrangement is inserted through the keyway in a locking relationship with the U-shaped anchoring bars. Sealing material between the traffic barrier element and the retaining wall and between the traffic barrier element and the ground adjacent to the retaining wall on the traffic side prevents the leakage of grout and leveling of the barrier element. Grout is then injected throughout the longitudinal channel and allowed to harden, thus providing a sealed and locked joint.

8. A method of constructing a precast concrete traffic barrier on a top surface of a wall structure having a traffic surface thereon, comprising the steps of;
-
a. a precast concrete traffic barrier element comprised of; i. a traffic facing sidewall having a longitudinal slot defined by a pair of spaced legs; ii. a longitudinal channel along a nether face; and iii. a second and opposite sidewall; iv. spaced first eyelet means supported by said barrier element; b. positioning said barrier element over said top surface of said wall structure so that said longitudinal channel is aligned with said top surface of said wall structure, said top surface having spaced second eyelet means; c. placing sealing material on said top surface of said wall structure and adapted to receive said second sidewall of said barrier elements; d. lowering said barrier element so that said second sidewall facially engages said wall structure by lengthwise contact thereagainst in a stacked relationship, and said second sidewall and said legs support said traffic barrier'"'"'s weight; e. coupling said barrier element and said wall structure by inserting an elongate locking rod through said first eyelet means and said second eyelet means; f. pouring cast-in-place concrete through said longitudinal slot to within said longitudinally extending channel encasing said first eyelet means, said second eyelet means, and said elongate rod; and g. building up said traffic surface to a point at the top of said legs. - View Dependent Claims (9, 10, 11, 12)
