- the Tendons in the inward-facing flange of the shaft or container section e.g. from the outside, assembled. Leave it high holding and contact forces in with the tendons achieve large areas. The power transmission is cheap near the crossings.
- the cavities for the abutment parts of the tendons are from the start molded into the section wall what the manipulation with the tendons simplified and as close as possible can be placed on the inward-facing flange.
- the Arrangement of the flange parts on the flat wall parts also the advantage of better demoldability in the Formation of the sections as injection molded parts.
- the levels and the curved wall areas with their transitions increase the structural strength of the sections or Section walls noticeable.
- Manhole or container has a uniform connection structure through the regularly arranged and on top of each other aligned tendons in the recesses.
- the shaft or container receives the static one Properties and the tightness of a one-piece container or shaft.
- the sections are easy and easy to transport and on site to the desired one Container or shaft size can be assembled. Of the The shaft or container must be dismantled or at any time remodel. An additional bracing of the sections is arranged by those in the curved wall areas Longitudinal ribs reached.
- the circulating Wall shoulder according to claim 18 divides the flat and the curved Wall areas in smaller and therefore more stable fields and overall increases the structural strength of the section. Furthermore, the flat wall areas are relative steep, which simplifies the connection of lines and an advantage when stacking the same sections is. It becomes a regular integrated one, so to speak Stiffening skeleton created in each section that is filled through the wall areas.
