Technical Field
[0001] The utility model belongs to the technical field of concrete pump pipes and relates to a fixing structure of a bent section of a concrete pump pipe. Background Art
[0002] Concrete pump pipe, also known as concrete delivery pipe, is an important component of concrete delivery equipment such as concrete pump trucks or trailer pumps. It is mainly used to continuously and efficiently transport the mixed concrete along the pipeline to the pouring site for construction pouring.
[0003] Concrete pump pipes are divided into many types, such as straight pipes, curved pipes, and reducers. The place where concrete is mixed is often at a certain distance from the place where concrete is poured. Therefore, multiple concrete pump pipes are often required to be connected to form a sufficiently long pipeline. In the process of conveying concrete, the concrete pump pipe has a large vibration, which will cause the entire concrete pump pipe to vibrate up and down, resulting in the problem of concrete pump pipe breakage, especially at the bends of the concrete pump pipe.
