Vertical anti-seepage and anti-pollution isolation method and composite isolation wall
The invention discloses a vertical anti-seepage and anti-pollution isolation method and a composite isolation wall, and the method comprises the following steps: excavating in-situ soil downwards along the periphery of a polluted site to form a vertical groove body; preparing bentonite slurry; bentonite slurry is injected into the tank body; preparing backfill soil according to a proportion, backfilling the groove body with the backfill soil, and mixing the backfill soil with the bentonite slurry to form the backfill soil and a bentonite wall body; when the strength of the backfill soil and the bentonite wall body reaches half of the design strength, non-aqueous reaction type two-component polyurethane high polymer is injected into the center of the backfill soil and the center of the bentonite wall body through a drilling-lifting grouting integrated construction technology to form an ultrathin anti-seepage high polymer interlayer, and the thickness of the interlayer is 3-6 cm; a composite separating wall for vertical seepage prevention and pollution prevention is formed in the tank body; the composite isolation wall is obtained by an isolation method; the composite isolation wall obtained through the isolation method has the advantages of being good in anti-seepage effect, high in dirt isolation performance, fast in isolation effect taking time, high in deformation resistance and shock resistance, long in service life, environmentally friendly and capable of saving energy.
本发明公开了一种竖向防渗阻污的隔离方法及复合隔离墙，方法包括：沿污染场地外周向下开挖原位土，形成竖向的槽体；配置膨润土浆；向槽体内注入膨润土浆；按比例配置回填土，回填至槽体，并与膨润土浆混合，形成回填土和膨润土墙本体；当回填土和膨润土墙本体强度达到设计强度的一半时，在回填土和膨润土墙本体中央通过钻孔‑提升注浆一体化施工工艺注入非水反应类双组份聚氨酯高聚物形成超薄防渗高聚物夹层，夹层的厚度为3‑6cm；在槽体内形成用于竖向防渗阻污的复合隔离墙；复合隔离墙由隔离方法得到；本发明隔离方法得到的复合隔离墙具有防渗效果好、隔污性能强、隔离见效时间快、抗变形和抗震能力强、使用寿命长、绿色环保节能的优点。
