Why is the concrete wall filled with long and thin white plastic pipes?
When the wall and the wall are wide, the wall bolts are used, and the through wall bolts are used to pull through the formwork so that the wall formwork can not run out of shape when playing the concrete. The utility model is arranged in the plastic pipe for easy placement and extraction, and is convenient for repeated use.
Mass concrete produces a lot of heat when it is solidified and must be released. Otherwise, it is easy to crack, so it is ventilated and cooled, but this possibility is the least. We usually use steel pipe.
Along the wall, it is possible to embed the wire through the wall.
