APPLICATION OF RESIN PIPES TO CONCRETE PUMP METHOD

The pipes used for concrete pump are generally made of steel, but resin pipes have been commercialized for the purpose of weight reduction. In this report, we conducted a pumping experiment using a resin pipe, and clarified the usefulness of the resin pipe and the pumpability when it is used. As a result, it became clear that the pumping pressure could be reduced by using a resin pipe. However, it was clarified that the resin pipe has lower rigidity than the steel pipe, and the deflection and deformation become larger during pumping.
