Today, our activity is pipe laying. Do you know about this?
These large pipes are called Reinforced Concrete Pipe (RCP). These are mainly used for drainage system. These are undeground utilities. They are being installed before having concrete pouring.
We use backhoe in laying large pipes, and we use manpower when sizes ranges at 300-450 mm. 600 mm pipes up to the largest one were being assisted by backhoe. We use c-clamp to hold the pipe. Our on going pipe laying is 1200 mm rcp.
Before rcp laying, bear in mind that we also put black sand as its bedding. And after laying, we put collars to hold the rcp in place especially when high pressure of water is entering the drainage. Then we put sand bedding again before backfilling.
That's it. Hope you learn something and I hope you enjoyed this post. Thank you!
