Self-restoring horizontal barrier structure
The invention relates to a self-restoring horizontal barrier structure which is used for pollution risk management and control of an industrial pollution site. The self-restoring horizontal barrier structure comprises a compacted soil cushion layer, an under-film protective layer, an artificial film impermeable layer, a liquid spraying film layer, an on-film protective layer and a clean soil layerwhich sequentially cover the pollution site from bottom to top. The self-restoring horizontal barrier structure provided by the invention has multi-layer protection, prevents pollution from diffusingupwards, and is good in blocking effect. The liquid spraying film layer additionally provided with a root inhibitor component is applied, so that the barrier structure can resist root puncture and has self-restoring property, the surface layer of the structure can be automatically restored to a closed state after being punctured by external force, damage and loopholes are reduced, and barrier failures are avoided.
本发明涉及一种自愈型水平阻隔结构，用于工业污染场地的污染风险管控，其包括自下而上依次覆盖于污染场地上的压实土垫层、膜下保护层、人工膜防渗层、液体喷涂膜层、膜上保护层、清洁土层。本发明提供的阻隔结构具有多层防护，阻断污染向上扩散，阻隔效果好。应用了添加阻根剂成分的液体喷涂膜层，使阻隔结构能够耐根穿刺且具有自愈性，受到外力刺破后结构表层能够自动恢复成密闭状态，减少破损、漏洞，避免阻隔失效。
