Abstract
The invention provides a construction method of a flexible vertical anti-seepage wall for blocking underground water pollution. The construction method comprises the following steps of: S101, carryingout construction measurement and positioning and paying off; S102, flattening a field; S103, carrying out high-pressure jet grouting piles on two sides of a pre-formed groove position; S104, arranging guide walls at the tops of the high-pressure jet grouting piles; S105, carrying out groove forming construction; S106, paving HDPE (high-Density polyethylene) geomembranes in a groove; S107, mutually sealing and connecting the adjacent HDPE geomembranes; S108, pouring a sealing material into the bottom of the groove to the bottoms of the HDPE geomembranes; and S109, carrying out clay backfillingon the upper part in the groove and connecting the sealing material at the bottom of the groove. By adopting the process provided by the invention, continuous closing and no-leakage-point pollution blocking can be realized in the vertical direction. A flexible anti-seepage material adopts the HDPE geomembranes and the service life of an anti-seepage system can reach 50 years; the permeability coefficient is less than 10< -7 >cm/S.
