Embodiment 1

[0027] Such as figure 1 As shown, a storage floor settlement control system includes a floor surface layer 1, a leveling layer 2, a reinforced mattress layer 3 and a reinforced composite foundation; the reinforced composite foundation is sequentially provided with a reinforced mattress layer 3, Leveling layer 2, floor surface layer 1; the reinforced composite foundation is reinforced by combining the deep cement mixing pile method 5 and the dynamic compaction method 7; wherein, the floor surface layer 1 is a steel fiber concrete floor surface layer 1, Its thickness is 195mm-205mm; Described leveling layer 2 is plain concrete leveling layer 2, and its thickness is 95mm-105mm; Described reinforced cushion layer 3 is the geotextile reinforced cushion layer filled with fine sand, and its thickness is 195mm-205mm.

[0028] The embodiment of the present invention is illustrated by taking a large-area heavy-duty warehouse as an example. In this embodiment, the natural foundation is ...

Abstract

The invention discloses a warehousing terrace sedimentation control system and a construction method thereof. The warehousing terrace sedimentation control system comprises a terrace surface layer, aleveling layer, a ribbed mattress layer and a reinforced composite foundation; the ribbed mattress layer, the leveling layer and the terrace surface layer are arranged on the reinforced composite foundation in sequence; and the warehousing terrace sedimentation control system can effectively solve the problem of nonuniform sedimentation of a warehousing terrace of a deep new-soil-filled foundation, and meets use requirements of the warehousing terrace. Compared with a conventional engineering pile scheme, a dynamic consolidation method and a deep stirring pile method are lower in production cost, and are both conventional foundation treatment methods; and a deep cement stirring pile adopting the ribbed mattress layer is combined with the dynamic consolidation method to reinforce the deep new-soil-filled foundation, so that the effects of reducing the foundation sedimentation and nonuniform sedimentation and homogenizing the foundation stress are more obvious.

Description

technical field [0001] The invention relates to a storage floor in civil construction engineering, in particular to a storage floor settlement control system and a construction method thereof, which can be applied to deep and newly filled foundations. Background technique [0002] With the rapid development of the logistics Internet economy, there are more and more demands for the construction of large-scale logistics storage plants, and the evaluation of the floor is one of the main criteria for storage renters. In domestic storage floor construction, the analysis of geotechnical conditions and foundation reinforcement are often neglected due to cost considerations, resulting in widespread settlement problems on the floor, making the storage floor unusable. [0003] During construction in inland areas of our country, artificially filled foundations are often encountered, which are generally recently piled up, have not yet completed self-weight consolidation, and have a rela...
