Abstract

A culvert pipe inlet arrangement includes a pan member and an inlet that is configured to be disposed within a culvert pipe is disclosed.

Claims (18)

1. A culvert pipe inlet arrangement for culvert pipes, comprising:

a pan member defined by first and second ends and a body portion between the first and second ends; and

an inlet section connected to and extending from the first end of the pan member, wherein the inlet section has a diameter less than an internal diameter of a culvert pipe such that the inlet section is configured to be received in frictional engagement with an interior surface of the culvert pipe, the inlet section further comprising a removed portion to allow for ends of the inlet section to be selectively moved toward one another to selectively vary a diameter of the inlet section.

2. The culvert pipe inlet of claim 1 , wherein the pan member flares outwardly from the first end to the second end.

3. The culvert pipe inlet of claim 1 , wherein the pan member has a bell shape.

4. The culvert pipe inlet of claim 1 , wherein the pan member includes upwardly extending side walls.

5. The culvert pipe inlet of claim 1 , wherein the upwardly extending side walls terminate in rolled edges.

6. The culvert pipe inlet of claim 1 , a spreader rod arrangement configured to be disposed within the inlet section to secure the inlet section against the interior surface of a culvert pipe.

7. The culvert pipe inlet of claim 6 , wherein the spreader rod arrangement includes a linear section having first and second threaded ends, and a tightening sleeve that receives the threaded ends, wherein rotation of the tightening sleeve in a first direction forces the threads outwardly of the sleeve to expand the perimeter of the spreader rod arrangement.

8. The culvert pipe inlet of claim 1 , a sleeve having first and second ends, wherein the first end is smaller than the second end such that the sleeve is tapered, and wherein the inlet section is disposed within the sleeve and the second end of the sleeve is fixed secure to the inlet section.

9. The culvert pipe inlet of claim 8 , a section disposed adjacent the second end of the sleeve that extends outwardly to form a stopper.

10. A culvert pipe inlet arrangement for use with culvert pipes, comprising:

a pan member defined by first and second ends and a body portion between the first and second ends;

an inlet section connected to the first end of the pan member, wherein the inlet section having a continuous diameter; and

a sleeve having first and second ends, wherein the first end is smaller than the second end such that the sleeve is tapered, further comprising a section disposed adjacent the second end of the sleeve that extends outwardly from the outermost diameter of the sleeve to form a stopper, and wherein the inlet section is disposed within the sleeve and the second end of the sleeve is secured to the inlet section.

11. The culvert pipe inlet of claim 10 , wherein the pan member flares outwardly from the first end to the second end.

12. The culvert pipe inlet of claim 10 , wherein the upwardly extending side walls terminate in rolled edges.

13. The culvert pipe inlet of claim 10 , wherein the sleeve is fixedly connected to the inlet section.
