Finally we had the chance inspecting the pipe after being in operation for some time. Following picture sequence shows the final steps of the operation and the completed installation.
The bracing is installed.
The utilisation of the timber in upright position is not ideal, but sufficient for this small dimension. For larger dimensions suitable adjustable spindles need to be implemented.
The end is sealed and the ventilation pipe for air release during the grouting is in place.
The Mixer supplies the pump with the cement grout.
View inside the starting manhole while the cement grout is pumped inside.
The customer decided to install the PST segments in the bottom halve of the manhole. The supply pipe for the cement grout is still in place and will have to be removed.
