Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a concrete pumping device for water conservancy projects. Background Art

[0002] The concrete pumping device in water conservancy projects is a technology developed to meet the needs of large-scale concrete construction. The construction of dam infrastructure, spillways and channels, etc., requires a large amount of concrete and is often carried out under complex and difficult terrain conditions, which puts higher requirements on the transportation and pouring of concrete.

[0003] However, after the construction of the dam's infrastructure, spillways and channels is completed, traditional concrete pumping devices for water conservancy projects often have residual concrete inside the pipes of the conveying device. If the contamination is not removed and cleaned in time or the cleaning is not thorough, the residual concrete will solidify and cause blockage in subsequent use. The traditional cleaning method is internal flushing, but there will still be some residue, and the stones in the concrete will cause serious scratches and bumps on the inside of the pipe. If the pipe is not replaced in time, it will rupture and be dangerous. For this reason, we have proposed a concrete pumping device for water conservancy projects. Utility Model Content

Take out the inner lining pipe 5 inside the delivery pipe 3 along the slide groove 12 at a single end, so as to flush the inside of the inner lining pipe 5 to prevent the residual concrete inside from solidifying. If the inner lining pipe 5 is found to be severely scratched and deformed, it can be quickly replaced to prevent the inside of the delivery pipe 3 from being damaged by concrete, and the removed adapter 4 should also be cleaned. After cleaning, align the slider 15 on the outside of the inner lining pipe 5 with the slide groove 12 inside the delivery pipe 3 and insert it into the delivery pipe 3, and connect each section of the delivery pipe 3 with the adapter 4, and place a sealing ring 13 between the delivery pipe 3 and the adapter 4 to prevent the internal concrete from leaking during subsequent use.
