Its function is to prevent water and soil from entering the construction site of the building, so as to drain water in the cofferdam, excavate the foundation pit, and build the building. The combined structure of Larsen steel sheet piles and I-beam waist beams is currently the most widely used structural form in the geotechnical waterproof structure of the foundation pit. The problem is that the enclosure formed by the Larsen steel sheet piles mainly plays a waterproof role, and its force bearing capacity is poor. The waist beam is installed on the inner side of the Larsen steel sheet piles, and its supporting performance is limited;
