Construction method for backfilling underground cantilever structure fat groove
A construction method for backfilling a fertilizer groove of an underground cantilever structure comprises the construction steps that S1, the fertilizer groove is divided into a lower backfilling area, a middle filling area and an upper backfilling area, the middle filling area is located under a cantilever part, the lower backfilling area is located under the middle filling area, the upper backfilling area is located above the lower backfilling area, the height of the middle filling area is 2.0-2.1 m, and the height of the upper backfilling area is 2.0-2.1 m; the width is 0.5-0.8 m greater than the width of the overhanging part; s2, waterproof treatment is conducted on the outer wall of the building and the bottom face of the overhanging part; s3, backfilling construction is conducted on the lower backfilling area; s4, a filling soil retaining structure with an inner cavity is constructed in the middle filling area, the filling soil retaining structure is tightly attached to the soil layer surface of the lower backfilling area, and the cantilever part serves as the top of the filling soil retaining structure; s5, the filling retaining structure is filled with foam concrete; and S6, backfilling construction is conducted on the upper backfilling area. The risk of uneven settlement of backfilled earthwork is effectively reduced, the construction efficiency is improved, labor is saved, and the method is economical and practical.
地下悬挑结构肥槽回填的施工方法，施工步骤包括：S1，将肥槽划分为下部回填区、中间填充区和上部回填区，中间填充区位于悬挑部位正下方，下部回填区位于中间填充区下方，上部回填区位于下部回填区上方，中间填充区的高度2.0~2.1米，宽度大于悬挑部位宽度0.5~0.8米；S2，对建筑外墙和悬挑部位底面分别做防水处理；S3，对下部回填区进行回填施工；S4，在中部填充区构建具有内空腔的填充挡土结构，填充挡土结构与下部回填区的土层表面贴紧，悬挑部位作为填充挡土结构的顶部；S5，向填充挡土结构中填充泡沫混凝土；S6，对上部回填区进行回填施工。本发明有效降低回填土方不均匀沉降的风险，提高施工效率，节省人工，经济实用。
