Title:
WATER-CONTAINING FLUID TRANSPORT PIPE AND TRANSPORT METHOD FOR WATER-CONTAINING FLUID
Document Type and Number:
WIPO Patent Application WO/2019/151449
Kind Code:
A1
Abstract:
Provided is a water-containing fluid transport pipe and a water-containing fluid transport method, wherein: firstly, when transporting water-containing fluids, pipe clogging does not easily occur compared to conventional pipes that use general structural steel or the like; and secondly, quality degradation in the water-containing fluid caused by significant changes in the temperature of the pipe itself due to environmental effects can be suppressed. This water-containing fluid transporting pipe has an innermost layer formed on an inner surface thereof and containing a material that has a water absorption rate of at most 0.2 mass% and a thermal conductivity of at most 10 W/m•K. The water-containing fluid is fresh concrete, and the pipe is preferably a pressure-feeding pipe for fresh concrete. This water-containing fluid transport method includes a step for transporting a water-containing fluid inside said pipe. This concrete pouring method includes a step for pressure-feeding fresh concrete inside said pipe.
