Moulds for manholes
Adjustable moulds for circular manholes
Manufacturing different element heights is made easy by combining a height-divisible core and a height adjustment system of the base ring.
Specifications of the manholes:
- Internal diameter 1000mm
- External diameter 1600mm
- Maximum outside height 2200mm
The heart of the mould is the hydraulically retractable inner core, which is divided into 3 separate segments: 1400mm + 300mm + 300mm. As a result there are 3 different basic heights of the inner core in the mould, which produce the desired element heights in conjunction with the height-adjustable ground ring. This is to avoid the box-outs and connector plates sticking out too far above the mould, which might hinder the pouring of the concrete.
Different mould parts:
- Hydraulically shrinkable inside mould 1400mm high
- 2 hydraulically shrinkable top-ups 300mm high
- Manually movable outside mould 2200mm high
- Box-outs 22,5° and 45° Â? Connector plates
