Problems solved by technology

[0002] In modern life, as buildings get taller, concrete pump trucks are used more and more widely. However, the existing concrete pump trucks use rubber pipes at the bends, which have a short service life. It is easy to be damaged, and when the concrete pump truck finishes transporting the concrete, the concrete will often flow back, resulting in waste of concrete
