An anti-seepage structure for groundwater

Abstract

The invention discloses a groundwater anti-seepage structure. The groundwater anti-seepage structure has the advantages that groundwater can be subjected to anti-seepage treatment, and accordingly, unfavorable natural phenomena caused by groundwater seepage, such as swamping, salinization, landslide and land subsidence, are avoided; under long-term infiltration, a geotextile protective layer protects geotextiles to ensure the anti-seepage effect; the groundwater anti-seepage structure has the advantages of reasonableness, safety, feasibility and the like; the landfill volume per unit area is high, the construction cost is low, the adaptability to deformation is high, water pollution is avoided, the engineering quantity is low, and the construction speed is high; a vacuum oil film is formedbetween contact surfaces of the two-layer geotextiles of an initial anti-seepage layer, so that the water anti-seepage performance can be improved greatly; through injection of quick-setting waterproofing agent slurry, grouting suction holes can be sealed through grouting, and the firmness of the groundwater anti-seepage structure can be improved; the drainage performance of a geotechnical composite drainage net can be guaranteed, and accordingly, the anti-seepage effect of an expansion anti-seepage layer is improved conveniently.

Description

technical field [0001] The invention relates to the technical field of groundwater, in particular to a groundwater anti-seepage structure. Background technique [0002] Ground water refers to the water that exists in the rock voids below the ground. In a narrow sense, it refers to the water in the saturated aquifer below the groundwater surface. Ground water is an important part of water resources. Due to its stable water quantity and good water quality, it is It is one of the important water sources for agricultural irrigation, industrial mines and cities, but under certain conditions, changes in groundwater can also cause unfavorable natural phenomena such as swamps, salinization, landslides, and land subsidence. [0003] However, the anti-seepage effect of groundwater currently on the market is not good, it is easy to cause the penetration of groundwater, lead to the loss of groundwater, and even change the surrounding environment, and after anti-seepage treatment, the ge...
