Dam's valves and gates are regularly checked and renovated to ensure the effective operation and safety.
Further to the successful Hongrin-Leman obturator project, Hydro Exploitation asked PXL SEALS to help them managing in this huge, new project.
Project: Obturator seals for Punt Dal Gall dam.
PXL SEALS solution:
The developed seal is in direct contact with the dam structure (on concrete). On that structure, it may have up to 40mm of unevenness : the sealing system must be able to fill this unevenness.
PXL SEALS followed the below steps to design and validate his sealing profile :
PXL SEALS worked with the partners to determine the requirements specification: bottom outlet obturator seal and baseplate obturator seal.
For economic reasons, the team decided to develop one single seal for both obturators (same issue).
To design this seal with its constraints (unevenness, bulk, etc.). PXL SEALS has been using its expertise and experience on this kind of project and its material knowledge for hydro seal.
Finite element analysis and test:
Once the seal design was done, PXL SEALS simulated the behaviour with FEA and bench test.
The final design is validated, once all FEA and tests have succeeded.
Manufacturing and on-site installation:
After manufacturing the seal by extrusion, PXL SEALS installed them on site on both obturators.
PXL SEALS succeeded in this project: no leakage on bottom outlet and baseplate obturators.
Punt Dal Gall project was very successful for PXL SEALS and all partners.
