Heat collection bag, device and method for solidifying and filling calcium sand foundation

Abstract

A device and method for collecting heat bags and solidifying and filling calcareous sand foundation, belonging to the field of civil engineering geological treatment technology. The solar heat collection bag comprises a transparent and permeable part and an insulation material, wherein the insulation material comprises a heat absorbing layer, an insulation layer, and a fabric layer. The heat absorbing layer, insulation layer, and fabric layer are fixedly combined from top to bottom to form an integrated transparent and permeable part. The edge of the transparent and permeable part is the first edge, and the edge of the insulation material is the second edge; The transparent heat permeable part and insulation material are combined into one through the first and second edges, forming a containment space between the transparent heat permeable part and the insulation material, so that the medium contained in the containment space can be heated by solar energy. The device includes a water intake component, a solar collector bag, and a water injection component. This method is implemented based on the device. This device and method can significantly improve the overall strength, liquefaction resistance, and seepage characteristics of calcareous sand foundation, with low cost and high application prospects.
