The invention discloses a novel woven arch structure and an assembling method thereof. The novel woven arch structure comprises at least three woven combination units, each woven combination unit comprises a component connecting hollow metal pipe and at least two combination components, and the component connecting hollow metal pipes are perpendicular to the combination components respectively. The middle positions of the combination components are bound and fixed to the component connecting hollow metal pipes respectively, and each combination component comprises a component core hollow metalpipe, an FRP pipe and a concrete sandwich filler layer. All the woven combination units in the novel woven arch structure are sequentially connected from front to back to form the arch structure, andthe woven arch structure has the advantages of being novel in design, good in breaking strength, good in bending strength and long in service life. The assembling method comprises the following stepsof a, determining the sizes of the combination components; b, preparing the combination components; c, assembling the woven combination units; and d, connecting the woven combination units. Accordingto the assembling method, the above woven arch structure can be effectively assembled.
