The concrete conveying pipe (used in conjunction with the concrete pump) forms a closed continuous conveying system, which can directly and quickly pump concrete from the ground mixing plant to a working surface several hundred meters high. This has completely changed the traditional construction method of low efficiency and long intervals in the transportation of tower crane hoppers, achieving high flow and uninterrupted pouring operations, significantly shortening the structural construction period, and is one of the key technologies to ensure that the construction of standard floors in modern high-rise buildings reaches the speed of "5-7 days per floor".
