[0045] Therefore, by adopting the utility model, a cantilever slab for placing the replacement strut is reserved in advance on the exterior wall of the basement. A fixing plate is connected at the corresponding position of the right flange of the H-shaped steel of the SMW method pile. The replacement strut is lifted by a tower crane and placed between the right flange and the exterior wall of the basement, and abuts against the right flange and the exterior wall respectively. The right end of the replacement strut is lifted and placed on the cantilever slab, and the lower part of the left end of the replacement strut is rotatably connected to the fixing plate in the front-back direction. The construction operation of the utility model is simple and fast, which can meet the construction requirements. The lower part of the left end of the replacement strut is rotatably connected to the fixing plate in the front-back direction. After the force transfer system for the backfilling of the foundation pit cushion is completed, the replacement strut can be lifted and recycled. There is no need to erect formwork support, which saves the construction period and can complete the placement of the replacement strut. The input of reinforced concrete is reduced, and the construction cost is saved.

[0046] The utility model is used in the construction field of the replacement strut for the middle floor slab of the basement. Through the recyclable replacement strut, while ensuring the operation safety and construction requirements, the repetitive work content is reduced, the work efficiency is improved, the construction cost is saved, and the construction progress is accelerated.
