The invention discloses a cantilever beam double-section type construction method. A cantilever beam comprises a head block and a tail block. The method comprises the steps that 1, a pair of clamping groove supports are positioned onto a main ship body, and two pairs of guide supports are positioned on the main ship body and fixedly connected with the main ship body; 2, a first slipping base located at the bottom of the head block is arranged into a clamping groove of one clamping groove support seat in a sleeved mode and limited to a set position; 3, the head block with the clamping groove supports is hoisted onto the main ship body to enable the clamping groove supports to be embedded into pre-set positions, and meanwhile the first slipping base is arranged into one guide support in a sleeved mode; 4, a bearing plate member and a slide rail plate member are installed into the clamping groove; 5, the tail block is installed. By means of the cantilever beam double-section type construction method, the installation sequence in the prior art is changed, the cantilever beam can be constructed in a carrying mode by the use of conventional hoisting and transporting equipment under the condition of the dock width being 76 m, the precision is high, the cost is low, and the construction duration is short.
