FINISHER WITH LID

Product for replacement

1. Exposing the shaft

  • The first step before laying the top layer is to uncover the shaft
  • The area around the shaft will be demolished, just as with the manhole cover replacement

2. Calculation of the composition

  • Always better to have fewer balancing rings
  • Count 10-20 mm of high-strength material on each joint

3. Fitting of rings

  • Moisten the concrete rings
  • The connecting surface must be supported in its entirety

4. Topping compound

  • Always with high-strength and resistance to chemical defrosting agents
  • If using formwork, the rings can also be connected with grout

5. Impregnation

  • Complete the entire area under the asphalt
  • It’s faster to use a spray bottle

6. Removal of makeshift parts

  • The temporary hatch is cleaned and prepared for further use
  • Checking the opening cleanliness

7. Installation of formwork

  • The formwork attaches to the carrier
  • The formwork on the carrier is placed in the prepared hole to ensure the correct height and directionality

8. Base asphalt layer

  • Warm asphalt concrete required
  • Clean the formwork surface

9. Compacting

  • Tighten the substrate very well so that the hole does not collapse
  • Proceed very carefully

10. Removal of formwork and carrier

  • Check the surface strength around the formwork
  • Remove the formwork and the carrier

11. Installing the hatch

  • The cover needs to be treated with mineral oil to prevent adhesion of asphalt
  • The hatch is inserted into the tightened hole so that it is 10 mm below the future road level

12. Laying the top layer

  • The finisher goes over the hatch and lays down the abrasive layer
  • The hatch remains in place

13. Compaction

  • The running layer is compacted by rollers
  • The hatch at least remains below the asphalt layer

14. Uncovering the hatch

  • The hatch is then uncovered
  • Remove dirt from the surface of the set

15. Extrusion

  • Only extrude the hatch out slightly and pad using asphalt concrete
  • Do not use already used or compacting asphalt concrete

16. Push the frame in

  • The self-levelling frame must be pressed into the warm pack
  • The last cylinder will do it, and only by vibrating

Resulting work

  • Perform a flatness check, remove debris
  • Ideal plane but dirty hatch
