Backfill structure for buildings above or near subways and construction method of backfill structure
The invention relates to a backfill structure for buildings above or near subways and a construction method of the backfill structure, belongs to the technical field of constructional engineering, and is used for solving the problem that the backfill demand cannot be met due to the situation that the conventional backfill soil for the buildings above or near the subways is too large in volume or insufficient in strength. The backfill structure comprises a casting surface layer, wherein the casting surface layer adopts a bubble concrete layer and a normal concrete layer from bottom to top; the thickness of the bubble concrete layer is 200 mm. The construction method comprises the following steps of firstly, erecting a side template above a subway main structure; secondly, carrying out casting to form the bubble concrete layer above the subway main structure, and reserving a construction joint; and then, when the bubble concrete layer reaches certain strength, carrying out casting to form the normal concrete layer above the bubble concrete layer, and carrying out maintaining for a period to form the casting surface layer.
