Document Type and Number:
Japanese Patent JP6909708
Kind Code:
B2
Abstract:
To provide a pumping distance specification system and a pumping distance specification method for concrete which reflect the concrete casting design plan at the construction site and can accurately specify the pumping distance at which pumping can be performed without blocking the piping.SOLUTION: A system 100 for reciprocatingly moving concrete in a piping 40 to specify a pumping distance by using a test apparatus 10 having the piping 40 and pumping means 11 includes the test apparatus 10 and a first arithmetic apparatus 50, in which the first arithmetic apparatus 50 has a pumping frequency calculation unit that calculates the pumping frequency by dividing the integrated pressure receiving amount, which is the product of the pumping reaction force received by the pumping means 11 from concrete and the pumping test time, by the required pumping pressure at the construction site and the total pumping time for pumping concrete by the pumping means 11, and a pumping distance specifying unit that calculates the distance at which the piping 40 is blocked by multiplying the pumping frequency by the amount of pumping by the pumping means 11, and uses it as the pumping distance.SELECTED DRAWING: Figure 1
