The utility model discloses a deep basal pit concrete pumping system, including main support, assistant support and pipeline, pipeline is arranged in carrying cement concrete to the deep basal pit, characterized in that: pipeline by the improving level tub of consecutive expert, first standpipe, well level pipe, second standpipe and down the horizontal nest of tubes become, first standpipe is fixed in the upper portion of main support, the second standpipe is fixed in on the assistant support, the both ends of well level pipe are fixed in respectively on main support and the assistant supportto be linked together with first standpipe and second standpipe respectively. The utility model discloses a concrete pumping system, the mobile in -process of concrete, the cushioning effect of levelpipe in the warp for the too fast stone that falls is kept in in well level pipe, after with to materials such as cement flow down after mixing once again, both guaranteed the homogeneity of concrete,avoided the stone large granule to lead to the fact the jam to the pipeline again.
