The invention discloses a method for a shallow part enhancement type soil-swell soil vertical antifouling separating wall. The method comprises the following steps: firstly, a field is flattened, a groove is excavated to a waterproof layer and the width of the shallow part groove is enlarged along two sides of the groove
central line, wherein the bottom portion of the width enlargement portion of the shallow part groove is located below an upstream water line of a lowest
pollution source; secondly, swell soil
slurry is used for protecting the wall in the groove, soil-swell soil wall body materials are backfilled from the bottom of the groove to replace
slurry, an impermeable plate is inserted in the center of the width enlargement portion of the shallow part groove and piling loading or vacuum prepressing is conducted at the top portion of the groove and the fields around the groove, so that the soil-swell soil backfilling materials begin to solidify under the collective action of
self weight and piling loading or vacuum prepressing and the soil-swell soil separating wall is formed in the shallow part, wherein the
pollution dispersal performance of the soil-swell soil separating wall is enhanced. Aimed at the fact that an antifouling protective screen in the shallow part is large in
pollution load and can be affected by the negative factors such as weather and temperature easily, the method for the shallow part enhancement type soil-swell soil vertical antifouling separating wall enhances impermeability and durability of weak links. The method for the shallow part enhancement type soil-swell soil vertical antifouling separating wall is strong in pertinency, convenient to construct, low in construction cost, environmental-friendly and capable of satisfying the
pollution prevention and control requirements.
