Construction method for backfilling of underground foundation pit excavation soil
The invention relates to a construction method for backfilling of underground foundation pit excavation soil. According to the method, on a site of original deep foundation pit excavation, the temporary excavation soil is stacked on the ground nearby a deep foundation pit in a sorted mode, then a filling technology is adopted for returning the excavation soil into the original deep foundation pit in a slurry mode, in the backfilling process, soil is made compact after backfilling through drainage, balanced matching and appropriate regulation and control of the same layer of soil are achieved, and in this way, backfilling is performed in a layer-by-layer mode until a design control ground elevation is reached. The construction method has the advantages that in backfilling of the underground foundation pit excavation soil, excavation and filling time of the deep foundation pit can be greatly shortened, excavation and filling costs of the deep foundation pit can be greatly lowered, and backfill resetting can be rapidly guaranteed without ramming machines.
