Pipeline flexible support suitable for large-diameter complex excitation

The invention relates to a pipeline flexible support suitable for large-diameter complex excitation. The pipeline flexible support comprises a lower rigid support body, the upper surface of the lower rigid support body is provided with an inwards-concave arc structure, the top face of the lower rigid support body is provided with an upper rigid support body in a matched manner, and the upper rigid support body is of an omega-shaped structure; a round hole is formed in the middle after the upper rigid support body and the lower rigid support body are matched, a plurality of flexible supporting blocks are distributed in the round hole, an annular structure is defined by the flexible supporting blocks, and a pipeline is placed in the annular structure; and an air inlet pipe is connected to the outer portion of each flexible supporting block, a one-way valve and a pressure adjusting valve are installed on each air inlet pipe, and the end of each air inlet pipe is connected with an air source.
