Disclosed is a hydraulic circuit for construction equipment, the hydraulic circuit controlling a confluence flow rate supplied from a hydraulic pump to a plurality of working apparatuses when a composite work is carried out by simultaneously operating the working apparatuses. The hydraulic circuit, according to the present invention, comprises: a CBP valve provided at the furthest downstream side of a supply flow path for a first hydraulic pump; a boom cylinder and a bucket cylinder that are driven by a hydraulic oil of a second hydraulic pump; a bucket control valve that controls the flow direction of the hydraulic oil supplied from the second hydraulic pump to the bucket cylinder when being switched; a first boom control valve that controls the flow direction of the hydraulic oil supplied from the second hydraulic pump to the boom cylinder when being switched; a second boom control valve that supplies hydraulic oil of the first hydraulic pump to the bucket cylinder or the boom cylinder through a joint flow
