PROBLEM: laying of a 300 diam funnel pipe below a river, without the possibility of installing temporary protections such as sheet piles or pilings. Lack of geological reports or accurate analyzes and presence of a very heterogeneous littoral situation (silt and gravel)
SOLUTION: organization of the construction site with temporary protections that allowed both the drainage works and the piping work.
RESULT: Installation of the pipeline within the established times
Application: Laying of sewer pipes across a river
Pump typology: Motor pumps + Submersible electric pumps + Generator set
No. of pumps used: 8
Wells + Free nesting
Gravel with traces of silt
