Among them, GCL composite vertical anti-seepage technology of our company plays an important role in the treatment project of informal domestic waste dump in faluqiao town. The engineering practice shows that the composite anti-seepage barrier composed of GCL and conventional vertical anti-seepage wall has excellent anti-seepage performance and chemical compatibility, and the construction is simple and the project cost is reasonable, which is very suitable for application in the field with high anti-seepage level requirements. , this technology provides a new idea and scheme for similar projects.
The informal domestic waste dump in Luqiao town is the original borrow pit of the nearby kiln plant, which covers an area of about 12099m2 and has a landfill capacity of about 60000m3. Due to historical reasons, the garbage dump has not taken any anti-seepage, isolation and exhaust measures, which has caused serious pollution to the surrounding air and water sources, affecting the health of the surrounding residents, and is the main source of pollution in this area. In order to thoroughly solve the problem of waste pollution, Dingyuan county government decided to seal the informal domestic waste storage site in Luqiao town on site, and our company provided GCL composite vertical anti-seepage technical support for the vertical anti-seepage system project of this project.
GCL composite vertical anti-seepage technology introduces GCL into vertical anti-seepage, with anti-seepage coefficient ≤ 1 × 10-7cm / s, meeting the requirements of environmental protection. This technology solves the shortcomings of the existing technology, such as low impervious level, poor chemical compatibility, and large construction difficulty. It is especially suitable for the vertical impervious field with high impervious requirements, such as pollution site repair, landfill, old simple landfill reconstruction, tailings dam and so on.
