Cement and Soft Mud Mixing Technique Using Compressed Air-Mixture Pipeline

Description:

A cement-mixing method using a compressed air-mixture pipeline for soft mud conveyance has

been developed for effective and economical disposal work. Plug flow generated in the pipeline

and compressed air are used to mix cement-based solidifier with mud in the pipeline. Uniform

cement mixing is achieved by injecting solidifier into an expander pipe with a larger diameter

than the pipeline.

The cement and soft mud mixing technique using the compressed air-mixture pipeline is a

prospective method for solidification of large land areas at low cost. It is usable at reclamation

sites that have previously required use of a new mixing barge in combination with the large

capacity compressed air-mixture pipeline transfer system. The technology is currently in the

research and development phase.
