More than 20 years static calculations
Besides IngSoft EasyPipe and IngSoft EasySchacht98 software, we offer individual static calculations as engineering service.
Today we present you one of our earliest projects:
Bottom plate and uplift verification of DN 1200 PE-HD manholes
We got the contract in April 1998. We determined the cross-section forces of the circular bottom plate according to Stiglatt/Wippel.
The figure shows the layout of the uplift assurance and two sections. Colours:
- Yellow = PE-HD parts (manhole sheet, inlet and outlet)
- Red = flange ring
- Green = Stiffener of the flange ring
- Grey = Concrete
- Blue = Reinforcement
Materials: PE-HD 80, Concrete B25, Rebar BSt 500 S/M
We suggested a reinforced concrete ring as an uplift counterbalance. A stiffened flange, welded to the manhole sheet, connects firmly concrete ring and the manhole sheet.
Since April 1998, we conducted more than 800 static calculations.
