Anti-settling construction method for soft soil foundation

Abstract

The invention discloses an anti-settling construction method for a soft soil foundation. The anti-settling construction method comprises a soft soil layer, the upper surface of the soft soil layer ispaved with a gravel layer, the upper surface of the gravel layer is fixedly paved with a quicklime bag layer, reinforced steel bars are fixedly embedded in the soft soil layer, the middle positions ofthe outer surfaces of the reinforced steel bars are fixedly embedded in the gravel layer and the quicklime bag layer, an internal concrete layer is fixedly poured on the upper surface of the quicklime bag layer, a steel bar cage is fixedly embedded in the internal concrete layer, the outer surface of the steel bar cage is fixedly welded to the ends of the reinforced steel bars, a clay layer is fixedly paved on the upper surface of the internal concrete layer, a compacted lime layer is fixedly paved on the upper surface of the clay layer, and an external concrete layer is fixedly poured on theupper surface of the compacted lime layer; and the construction method can improve the stability of the foundation effectively, the subsequent maintenance does not affect an underlying structure, andthe construction method is safe and stable, and beneficial for construction use and promotion.

Description

technical field [0001] The invention relates to the field of foundation construction technology, in particular to a subsidence prevention construction method for soft soil foundations. Background technique [0002] Under the current construction conditions, we will encounter different geological foundations for construction, especially soft soil foundations. Because of their soft texture, they are easy to sink and the construction is difficult. [0003] However, most of the existing soft soil foundation construction methods directly use the repeated rolling method of road rollers. Although the surface layer can be reinforced, its anti-settling effect is poor. Rolling pressure, shallow compaction depth, construction effect is not ideal, so a new construction method needs to be proposed. Contents of the invention [0004] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of anti-settlement construction method of s...

Problems solved by technology

[0003] However, most of the existing soft soil foundation construction methods directly use the repeated rolling method of road rollers. Although the surface can be reinforced, the anti-settling effect is poor. When encountering heavy rain, the foundation stability is insufficient, and it is limited Rolling pressure, shallow compaction depth, unsatisfactory construction effect, so a new construction method needs to be proposed
