The invention relates to a basement outer wall foundation trench reworked material backfill compaction system and a construction method. The basement outer wall foundation trench reworked material backfill compaction system and the construction method are characterized in that the basement outer wall foundation trench reworked material backfill compaction system comprises a humidification device and a compaction device; and the construction method mainly comprises the steps: water in a water-collecting well and a drainage macadam gravel layer are pumped into a water storage tank, a reworked material is laid in a layered mode, then the humidification device conveys the water in the water storage tank to the reworked material, then the reworked material is compacted in a layered mode throughthe compaction device, the compaction device comprises a retractable support, a retractable bottom plate and a rear connection plate, in the compaction process, the overall width of the retractable bottom plate and the rear connection plate is adjusted according to widths of foundation trenches, and the length of the retractable support is adjusted according to depths of the foundation trenches.The basement outer wall foundation trench reworked material backfill compaction system has the characteristics of being convenient to demount and mount and high in construction efficiency and can be suitable for backfill compaction of the basement outer wall foundation trenches with the different depths.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a backfill compacting system and a construction method of a basement external wall foundation groove humidification type regenerated material. Background technique [0002] Generally, Larsen steel sheet piles are used as support for the foundation pit of urban buildings. The operation surface reserved for construction will not be too large. After the construction of the underground structure is completed, a deep and narrow foundation groove will be formed on both sides. For deep and narrow The compaction control of the backfill soil in the foundation trench, the general construction method is difficult to meet the compaction requirements of the specification and design requirements. [0003] For the conventional construction of the above-mentioned narrow foundation trenches, artificial impact rams are used for layered compaction and "water ramming method"; howeve...
