Embodiment 1

[0095] The process of preparing type I composite anti-seepage components: mix solid materials (aluminate cement, magnesia, natural sand, fly ash) evenly, then add water for the first stirring, then add PVA fiber and water for After the second stirring, the high-ductility fiber slurry is obtained, and the high-ductility fiber slurry is poured into the mold through the pouring equipment to form a prefabricated component. The length, height and thickness of the prefabricated component are 2m*10cm*8m respectively.

[0096] In this embodiment, the Type I composite anti-seepage component includes the following components in terms of mass percentage:

[0097] Aluminate cement 23.52%,

[0098] Magnesium Oxide 0%,

[0099] Natural sand 17.79%,

[0100] Fly ash 40.82%,

[0101] Water 16.24%,

[0102] Polycarboxylate superplasticizer 2.18%,

[0103] The fiber PVA volume dosage is 0.8-1.2% of the total volume of the high ductility cement slurry.

Embodiment 2

[0105] The process of preparing the prefabricated anti-seepage component is the same as that of Example 1, except that:

[0106] In this embodiment, the Type I composite anti-seepage component includes the following components in terms of mass percentage:

[0107] Aluminate cement 23.52%,

[0108] Magnesium Oxide 1.22%,

[0109] Natural sand 17.79%,

[0110] Fly ash 39.05%,

[0111] Water 16.24%,

[0112] Polycarboxylate superplasticizer 2.18%,

[0113] The fiber PVA volume dosage is 0.8-1.2% of the total volume of the high ductility cement slurry.

Embodiment 3

[0115] The process of preparing the prefabricated anti-seepage component is the same as that of Example 1, except that:

[0116] In this embodiment, the Type I composite anti-seepage component includes the following components in terms of mass percentage:

[0117] Aluminate cement 23.52%,

[0118] Magnesium Oxide 2.44%,

[0119] Natural sand 17.79%,

[0120] Fly ash 37.28%,

[0121] Water 16.24%,

[0122] Polycarboxylate superplasticizer 2.18%,

[0123] The fiber PVA volume dosage is 0.8-1.2% of the total volume of the high ductility cement slurry.

Abstract

The invention discloses an environment-friendly composite anti-bypass-seepage flexible vertical isolation system and an installation method. The isolation system comprises anti-bypass-seepage components used for blocking pollutants in underground water and soil; each anti-bypass-seepage component comprises a prefabricated fiber reinforced cement-based material or a carbonized magnesium oxide-based material; a closing bolt with two reserved openings is formed on the surface of each anti-bypass-seepage component; the two anti-bypass-seepage components clamp the same flexible anti-seepage wall; and the flexible anti-seepage wall is composed of a rectangular high-density polyethylene geomembrane. The system can solve the problem of leakage caused by poor contact between the geomembrane and a water-tight layer at the bottom of a tank, and can keep the anti-seepage performance under extreme earthquakes or large geological activities. Environment-friendly material magnesium oxide is adopted, component formation is accelerated through a carbonization method, and the positive effects that the environment-friendly materials are comprehensively utilized, carbon dioxide is absorbed, anti-bypass-seepage materials are efficiently produced, and high ductility is achieved can be achieved.

Description

technical field [0001] The invention relates to the technical field of ecological environment restoration, in particular to an environment-friendly composite anti-seepage flexible vertical isolation system and an installation method. Background technique [0002] With the rapid development of industrialization in our country, the damage to the environment is also becoming more and more serious. In particular, some chemical and mining companies have not taken anti-seepage measures for the existing solid waste dumps, mine heap leaching sites, tailings ponds, etc., causing toxic and harmful substances to endanger the ecological environment through various channels, pollute the soil and groundwater, and seriously Affect people's normal life and health. [0003] With the advancement of technology, the anti-seepage problems of storage yards, landfills and tailing ponds of chemical and mining enterprises have been effectively solved. Some vertical anti-seepage technologies, such ...
