The invention discloses a construction method for clustered type assembling arch ribs. The construction method adopts a clustered type assembling method. The construction method comprises the following steps of laterally dividing arch ribs into a plurality of arch rib bunches arranged in parallel for step-by-step construction; firstly assembling each of the arch rib bunches in the longitudinal direction one by one; and after assembling each of the arch rib bunches is completed, performing lateral permanent connection, namely completing the construction of the arch ribs. According to the construction method disclosed by the invention, according to the span size of the arch ribs, the arch ribs are divided into the arch rib bunches arranged in parallel for step-by-step construction, and the divided arch rib bunches are light in weight, so that the required bearing capacity of a steel structure arch frame is low, the using of basal materials and equipment is reduced, the construction cost is reduced, the construction cycle is reduced, and potential safety hazards to foundations of peripheral environment are avoided.
