A METHOD FOR EXECUTING ISOLATION WALL OF DIRTY WATER IN SEWAGE TREATMENT PLANT

摘要

The present invention provides a water barrier in a sewage and wastewater purification treatment facility in which a large maternal infiltration trench is installed on a sediment or cut soil to treat a large scale of single or combined manure and household sewage. It is about the construction method, and the impervious layer is present at the site where the maternal infiltration trench is installed, so that the leachate is leaked to the neighboring state without being completely processed, and the order wall which prevents the adverse effect in advance is quickly installed at low cost. Even if an impermeable layer exists in the vicinity of the site where the maternal infiltration trench is installed, rainwater is introduced into the untreated leachate side, thereby preventing the mixing phenomenon.;To this end, in which the capillary infiltration trench 3 for sewage treatment has been constructed, the wave space is deeper than the impermeable layer 7 along the cut surface 9 of the land 10 or the cut surface 9 of the cut 8. Forming a portion 12, erecting a sheet-shaped order member 14 made of an impermeable material in the space portion 12, and filling the space portion 12 with soil 18 to fill it up. It is a construction method to form the order wall.
