Abstract

A device for reinstatement of a micro-trench that includes a hopper. The hopper includes a top opening and a bottom opening, the top opening being larger than the bottom opening. The device also includes a valve portion connected to the bottom opening of the hopper and a tube connected to the valve portion. The device also includes a dynamic plate portion including a top opening, a bottom opening, and a conduit between the top and bottom openings. The top opening of the plate portion is connected to the tube, and the bottom opening includes a length and a width. The dynamic plate portion allows the device to maintain positive contact with the pavement even when the surface of the pavement is angled or uneven.

Claims (36)

1. A device for manual reinstatement of a micro-trench comprising a handle for manual guidance of the device;

a hopper comprising a first opening and a second opening, wherein the first opening is at a location higher than the second opening within the hopper;

a valve portion connected to the second opening of the hopper;

a tube connected to the valve portion; and

a dynamic plate portion comprising a top opening, a bottom opening, and a conduit between the top and bottom openings, the top opening connected to the tube and the bottom opening comprising a length and a width.

2. The device of claim 1 , wherein the valve portion comprises a top portion, a bottom portion, and a valve positioned between the top portion and the bottom portion, the top portion connected to the second opening of the hopper and the bottom portion connected to the tube.

3. The device of claim 2 , wherein the valve of the valve portion is mechanically-actuated.

4. The device of claim 1 , wherein the device further comprises a frame support; and

wherein the hopper is positioned within the frame support and is rotatably connected to the frame support.

5. The device of claim 4 , wherein the device further comprises one or more shafts connected to the frame support and the plate portion.

6. The device of claim 5 , wherein the device further comprises a camera mounted to the frame support.

7. The device of claim 1 further comprising a mixer located adjacent to the hopper.

8. A device for reinstatement of a micro-trench comprising;

a hopper comprising a first opening and a second opening, wherein the first opening is at a location higher than the second opening within the hopper;

a panel that supports the hopper;

a valve portion connected to the second opening of the hopper;

a tube connected to the valve portion; and

a dynamic plate portion comprising a top opening, a bottom opening, and a conduit between the top and bottom openings, the top opening connected to the tube and the bottom opening comprising a length and a width; and

a plurality of wheels connected to the panel; whereby the tube allows the dynamic plate portion to move.

9. The device of claim 8 , wherein the device is manually powered.

10. The device of claim 8 , wherein the device is machine-powered.

11. The device of claim 8 , wherein the valve portion comprises a top portion, a bottom portion, and a valve positioned between the top portion and the bottom portion, the top portion connected to the second opening of the hopper and the bottom portion connected to the tube.

12. The device of claim 8 , wherein the valve of the valve portion is mechanically-actuated.

13. The device of claim 8 , wherein the valve of the valve portion is electronically-actuated.

14. The device of claim 8 further comprising a mixer connected to the panel and located adjacent to the hopper.

15. A method for reinstating a micro-trench, the method comprising:

presenting a device comprising a handle for manual guidance, a hopper comprising a first opening and a second opening, wherein the first opening is at a location higher than the second opening within the hopper, a valve portion connected to the second opening of the hopper, a tube connected to the valve portion, and a dynamic plate portion comprising a top opening, a bottom opening, and a conduit between the top and bottom openings, the top opening connected to the tube;

positioning the bottom opening of the dynamic plate portion over a micro-trench;

dispensing material through the bottom opening of the dynamic plate portion into the micro-trench;

moving the hopper along the micro-trench such that the bottom opening of the dynamic plate portion maintains its position above the micro-trench; and

leveling the material dispensed into the micro-trench via the dynamic plate portion.

16. The method of claim 15 , wherein the moving of the hopper along the micro-trench includes machine-powered movement.

17. The method of claim 15 , wherein the moving of the hopper along the micro-trench includes manual-powered movement.

18. The method of claim 15 , wherein the positioning of the bottom opening of the dynamic plate portion over a micro-trench is conducted through a camera.

19. The method of claim 15 , wherein the dispensing of the material further comprises dispensing the material through the hopper and the tube.

20. The method of claim 15 further comprising mixing material within a container adjacent to the hopper to enable mixing near a point of application.
