What preparatory work is necessary for the shaft extensions?
The underground around the shaft should be compacted. Furthermore, a level support surface, preferably with chippings, 16cm below the manhole edge must be created.
Which works are still required afterwards?
None. Only push the sealing plugs into the threaded sleeves. Thus, the assembly is completed and the component can be filled.
Is the component reusable?
Yes. In case of renewal or rework, in case of settlement, the component can be attached and removed again. After completion of the work, the enclosure is simply reused as usual.
