The invention discloses an efficient green support changing type basement foundation pit construction method. The method comprises the following steps that fender posts and stand column piles are constructed below a natural ground plane; digging downwards from a natural ground plane to a supporting bottom surface, and then constructing a supporting beam; after the supporting beams reach the design strength, excavation is conducted to a bottom plate (the process is repeated for multiple supporting beam projects), and a concrete cushion layer is poured on the bottom plate; concrete is poured on the cushion layer to the edge of the fender post, and a bottom plate replacement support is formed; constructing to form a first concrete outer wall and a first top plate of a negative second layer; after the strength of the first concrete outer wall meets the requirement, the fertilizer groove is filled with liquid backfill materials; an adjustable steel replacement support is installed above the liquid backfill material, and then a supporting beam is dismantled; and constructing to form a second concrete outer wall and a second top plate of a negative layer (for more than two layers of basements, repeating the process), removing the adjustable steel replacement support, and after the strength of the second concrete outer wall meets the requirement, continuing to fill the liquid backfill material into the fertilizer groove until the backfill is completed.
一种高效的绿色换撑式地下室基坑施工方法，包括以下步骤：在自然地平面下方施工围护桩和立柱桩；从自然地平面向下挖至支撑底面，然后施工支撑梁；待支撑梁达到设计强度后，开挖至底板(对于多道支撑梁项目，重复上述过程)，在底板上浇筑混凝土垫层；在垫层上浇筑混凝土，浇注至围护桩边，形成底板换撑；施工形成负二层的第一混凝土外墙和第一顶板；待第一混凝土外墙的强度达到要求后，向肥槽中填液态回填料；在填液态回填料上方安装可调钢换撑，然后拆除支撑梁；施工形成负一层的第二混凝土外墙和第二顶板(对于超过2层地下室，重复上述过程)，拆除可调钢换撑，待第二混凝土外墙的强度达到要求后，继续向肥槽中填液态回填料，直至回填完成。
