[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 The utility model provides a technical solution: an indoor anti-seepage floor structure of an industrial building in a non-ferrous metal processing project, comprising a compacted rammed earth layer 1 with a compaction coefficient of not less than 90%, the compacted rammed earth layer 1 being rammed into the soil by crushed stones with a thickness of 150 mm; a fine stone concrete layer 2 is arranged on the upper surface of the compacted rammed earth layer 1, specifically, a 30 mm thick C20 fine stone concrete slope leveling layer is used to smooth the thinnest part of the compacted rammed earth layer 1.

[0016] The upper surface of the fine stone concrete layer 2 is provided with a waterproof blanket layer 3, which is a GCL natural sodium-based bentonite waterproof blanket with a tensile strength of not less than 400N, a peeling strength of not less than 65N, and a permeability coefficient of not more than 5×10 -9 cm / s, bentonite content ≥5.0kg / m 2 .

[0017] Natural sodium-based bentonite waterproof blanket, as an anti-seepage liner, can solve the problems of isolation and anti-leakage and has strong anti-destructive properties.

[0018] The upper surface of the waterproof blanket layer 3 is provided with a geomembrane layer 4, which is a high-density polyethylene anti-seepage layer with a thickness of 1.5 mm. As an anti-seepage membrane, the HDPE geomembrane can effectively prevent water, oil, waste, etc. from penetrating into the ground.

[0019] The upper surface of the geomembrane layer 4 is provided with a geotextile layer 5, and the geotextile layer 5 is 400g / m 2 The filament geotextile layer is used as the protective layer of the geomembrane to protect the anti-seepage layer from damage.
