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 new huge project.
Project: Obturator seals for Punt Dal Gall dam.
PXL SEALS solution:
The seal developed is in direct contact with the dam structure (on the concrete). On this structure, it may have until 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 economical reasons, the team decided to develop one single seal for both obturators (same problematic).
To design this seal with its constraints (unevenness, bulk, etc.). PXL SEALS used its expertise and experience on this kind of project and his 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 succeed.
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.
