Marine bored piles are installed over water bodies such as canal, river, sea, etc. Steel deck platforms are normally built as working platform for boring equiment to work on.
The marine bored piles can be cast right up to marine structure as column / pier with permanent casings. This will eliminate the need to build pile cap or pier under marine condition which is costly and time consuming.
A specially designed "catcher" is used to prevent pollution to water bodies during boring and concrete casting.
