PUMPING DISTANCE SPECIFICATION SYSTEM AND PUMPING DISTANCE SPECIFICATION METHOD FOR CONCRETE, AND OPTIMUM COMPOUND SELECTION SYSTEM AND OPTIMUM COMPOUND SELECTION METHOD FOR CONCRETE
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
【課題】施工現場におけるコンクリート打設計画が反映された、配管閉塞せずにポンプ圧送できる圧送距離を精度よく特定することのできる、コンクリートのポンプ圧送距離特定システムとポンプ圧送距離特定方法を提供する。【解決手段】配管４０と圧送手段１１とを有する試験装置１０を用いて、配管４０内でコンクリートを往復移動させてポンプ圧送距離を特定するシステム１００であり、試験装置１０と第一演算装置５０を備え、第一演算装置５０は、圧送手段１１がコンクリートから受ける圧送反力と圧送試験時間との積からなる積算受圧量を、施工現場における必要圧送圧と圧送手段１１にてコンクリートを圧送している総圧送時間で除してポンプ圧送回数を算定するポンプ圧送回数算定部と、ポンプ圧送回数に圧送手段１１による送出し量を乗じることにより、配管４０が閉塞する距離を算定してポンプ圧送距離とするポンプ圧送距離特定部と、を有する。【選択図】図１
