Anti-leakage facility for drainage pipeline in collapsible loess area

The utility model provides an anti-leakage facility for a drainage pipeline in a collapsible loess area, belongs to the technical field of water prevention, and solves the technical problems that the existing drainage pipeline cannot be normally used due to inclination of a building or breakage of the pipeline and the like caused by uneven settlement of the collapsible loess area due to water leakage. The anti-seepage facility for the drainage pipeline in the collapsible loess area comprises a permeable layer and a waterproof layer, a plurality of supporting layers are arranged between the permeable layer and the waterproof layer, a water passing channel is formed between every two adjacent supporting layers, and a flow guide pipe is communicated with one connecting edge of the permeable layer and the waterproof layer. The utility model has the advantage of preventing the pipeline from generating adverse effect on the collapsible loess area when the pipeline leaks. 本实用新型提供了一种湿陷性黄土地区排水管道防渗漏设施，属于防水技术领域，它解决了现有排水
