The traditional support system basically adopts cast-in-place construction, is disposable, has high cost and can not be recycled, and particularly when the anchor is adopted for supporting, an anchor rod (cable) is remained underground to generate underground garbage, thereby influencing the development and utilization of underground space outside a pit. In terms of the double-row steel pipe piles commonly adopted at present, the double-row steel pipe piles are widely designed and used under the conditions that the surrounding environment is complex and the inner support in a pit is inconvenient to use, and in order to ensure the integral rigidity of the double-row steel pipe piles, the double-row steel pipe piles are generally connected together by adopting the cast-in-place reinforced concrete crown beams, so that the integral rigidity of the double-row steel pipe piles is increased. Compared with single-row piles, the double-row piles have higher supporting performance, but the steel pipes are difficult to recycle after the foundation pit is backfilled. If the steel pipe pile needs to be recycled, the reinforced concrete crown beam needs to be broken, and a large amount of manpower and material resources are needed. Therefore, the materials are not recycled in the engineering, which causes material waste and is not in accordance with the engineering concept of green environmental protection.
