The invention provides a fluid control circuit, a hydraulic control circuit, and a construction machine. This fluid control circuit is provided with: a first circuit that conveys a first fluid ejectedfrom a first pump to a first actuator by means of a first operation switching valve; a second circuit that conveys the second fluid ejected from the second pump to the second actuator by means of thesecond operation switching valve; and a merging circuit that merges the second surplus fluid in the second circuit and the first fluid, and merges the first surplus fluid in the first circuit and thesecond fluid.

    本发明提供流体控制回路、液压控制回路以及施工机械。本发明的流体控制回路具备:第1回路,其利用第1操作切换阀向第1致动器输送从第1泵喷出的第1流体;第2回路,其利用第2操作切换阀向第2致动器输送从第2泵喷出的第2流体;以及合流回路,其使所述第2回路中的第2剩余流体与所述第1流体合流,使所述第1回路中的第1剩余流体与所述第2流体合流。
