5.1 seawall

hello,
How many flap valves are there on the seawall? also how big are they and it there any resources that we could access that shows the current inner design? we have assumed that it is a swing check valve but we cant find the info on the specifics.
thanks

Hi Lily,

There are 3 (1200*450) RCBC flaps. . This is project scope from the construction company who were awarded the work.

The flaps are situated near the church, you can take a closer look at the interactives. Hope that helps.

Cheers,
Sai

Hello,

What is the current lifespan or maintenance frequency of the flap design? Also what failures are most common, hinge pin or hinge mount failure, flap failure, sealing rings, etc.

Found some brief information on this but not specifics.

Thanks,
Toby

hello, something my team and i have just noticed is that it doesn’t specify what part of the valve is corroding. we had assumed that it just the stainless steal pin but looking at the image of the flaps the fiber glass looks to be in worse shape than the pin. just need to know as our design solution is heavily related to replacing the materials so we need to know if the fibre glass should also be replaced.
thanks for your help

Hi Lily,

It’s good that you have documented all those observations. Unfortunately, we don’t have access to the detailed drawing and real-time assessment of the affected components.

Our ultimate goal is to have an operational seawall drainage system that is fit for purpose. This can be achieved through the use of appropriate materials and regular maintenance.

Considering the drainage system as a whole and given your observations, I suggest you propose different design alternatives (for example – only replacing component x or replacing component x and the fiberglass).

These design alternatives may have different associated risks and opportunities, such as cost, performance, etc. Mapping your design alternatives as a team will help you to make informed decisions.

All the best in your project,
Jean

Hi there,

We’re looking to put in a inexpensive drainage system and then repurpose the now drained land for the community use, specifically adolescents. I’m trying to figure out what kinds of activities and sports local kids enjoy on Saibai. Also, I’m wondering if adding a playground might clash with their local culture. Any advice would be really helpful!

Hi Samuel,

I suggest that you have a look at the Saibai Community Booklet 2012 and the TSIRC Community Plan 2009-2029. What activities that count as cultural intrusion may be a subjective matter for the community. These documents will give you an idea about the existing recreational facilities and the community’s goals specific to art culture and heritage.

I hope this helps!

Regards,
Jean
