The invention relates to a double-rocker-arm floor derrick, a control system and a construction method, and the double-rocker-arm floor derrick comprises a derrick which comprises a derrick body, two rocker arms hinged to the derrick body, two variable-amplitude pulley blocks for controlling the rocker arms to swing and two hoisting pulley blocks arranged on the rocker arms; the power mechanism comprises a hydraulic power source, four groups of execution units driven by the hydraulic power source and four groups of tail brackets in one-to-one correspondence with the execution units, two groups of execution units are connected with the two groups of variable-amplitude pulley blocks through steel ropes, and the two groups of execution units are connected with the two groups of hoisting pulley blocks through steel ropes; and the hydraulic power source controls the two groups of execution units connected with the variable-amplitude pulley block to synchronously act and controls the two groups of execution units connected with the hoisting pulley block to synchronously act. Linkage control of the double-rocker-arm floor derrick can be achieved, unbalance loading of the double-rocker-arm floor derrick is monitored and adjusted in real time, the construction method of the double-rocker-arm floor derrick is standardized, and the use safety of the double-rocker-arm floor derrick is improved.
