Double-layer HDPE (high-density polyethylene) structure anti-seepage system of red mud storage yard backwater
The invention discloses a double-layer HDPE structure anti-seepage system for a red mud storage yard backwater pool, belongs to the technical field of water pool seepage prevention, solves the problem that the red mud storage yard backwater pool is prone to seepage, and adopts the technical scheme that the system mainly comprises an upper HDPE film, a lower HDPE film and a supporting structure arranged between the upper HDPE film and the lower HDPE film; the supporting structure 3 is a geotechnical composite drainage net with a two-side reverse filtering effect, the thickness of the geotechnical composite drainage net is 5.00-7.00 mm, the upper HDPE film is provided with an upper film protection layer, a lower film protection layer 5 is arranged below the lower HDPE film 2, the upper film protection layer 4 and the lower film protection layer 5 are made of filament anti-sticking needle-punched non-woven geotechnical cloth, and the strength of the upper film protection layer 4 and the strength of the lower film protection layer 5 are 18-30 N/m.
本发明公开一种赤泥堆场回水池双层HDPE结构防渗系统，属于水池防渗技术领域，解决赤泥堆回水池易渗漏的问题，解决该问题的技术方案主要包括上层HDPE膜、下层HDPE膜以及设于上层HDPE膜与下层HDPE膜之间的支撑结构，所述支撑结构3为具有两面反滤作用的土工复合排水网，其厚度为5.00～7.00mm，所述上层HDPE膜设有上层膜保护层，所述下层HDPE膜2下方设有下层膜保护层5，上层膜保护层4与下层膜保护层5为长丝防粘针刺非织造土工布，强度为18～30N/m。
