Construction method of flexible vertical anti-seepage wall for blocking underground water pollution
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.
本发明提供一种用于地下水污染阻隔的柔性垂向防渗墙施工方法，包括如下步骤：S101、施工测量和定位放线；S102、对场地进行平整；S103、对预计成槽位置两侧实施高压旋喷桩；S104、在高压旋喷桩顶部设置导墙；S105、进行成槽施工；S106、对HDPE土工膜进行槽内铺设；S107、将相邻的HDPE土工膜相互密封连接；S108、在槽底部灌注密封材料至HDPE土工膜底部；S109、槽内上部进行粘土回填，衔接槽底部的密封材料。采用本发明工艺，可以在垂向方向上实行连续闭合无漏点阻隔污染。柔性防渗材料采用高密度聚乙烯(HDPE)土工膜，防渗系统服务年限可达到50年，渗透系数满足小于10‑7cm/s。
