Abstract
Description
technical field
[0001] The invention relates to a stringing tube used in concrete pouring in the field of building construction, in particular to a concrete stringing device capable of preventing decoupling and changing direction, which belongs to special equipment for concrete pouring construction. Background technique
[0002] With the development of large-scale engineering construction, it is often necessary to pour large concrete structural parts, but when the free fall height of concrete exceeds 2 meters, segregation will occur, resulting in poor appearance of concrete structural parts, sand grains, exposed aggregates, Reinforcement exposure and other phenomena, and the concrete strength is greatly reduced, which seriously affects the bearing capacity of concrete structural parts. Therefore, the poured concrete for pile foundations exceeding 2 meters must be transported to the construction field by conduits, stringers or chutes.
[0003] The string tube refers to the tu...
