Pumping distance determining system for concrete and pump delivery distance determination method

摘要

Problem to be solved: to provide a pump pressurizing distance determining system and a pump pressurizing distance specifying method capable of accurately specifying a pressure feed distance capable of pumping and pumping without piping.Fill the piping 40 of the test device 10 with concreteAlternately, the pressing means 11 is operated alternatelyThe concrete is reciprocated over the time of pumping test until piping obstruction.Allowable integrated pressureIdentify the pumping distance based on the amount of planned load in the particular construction siteThe pumping and pumping distance system 100 of concreteFurther comprising an arithmetic unitThe arithmetic unitCompressive force exerted by concrete under pressure 11An allowable integrated pressure amount calculating section 510 for calculating an allowable accumulated pressure amount comprising a product with a press test timeA data storage unit 530 for storing planned load amountsThe pump pressurizing distance calculating section 520 is provided for calculating the pump delivery distance based on the allowable integrated pressure receiving amount and the planned load amount.Diagram
