Problems solved by technology

[0003] Currently publicly available practices on groundwater permeable reactive walls are all focused on the treatment of shallow groundwater on the surface, and cannot achieve complex geological conditions, contaminated groundwater, or deep soil restoration; moreover, general-purpose groundwater permeable reactive walls will The repair function of the groundwater reaction wall is passivated and the repair efficiency becomes poor. In this case, there must be the problem of incomplete pollution control; in addition, the replacement of the reaction medium in the infiltration reaction wall basically requires reinstallation of the reaction wall system. Large excavation method makes it difficult to standardize the repair medium, which leads to the problem of secondary pollution, and this shortcoming greatly restricts the promotion and use of groundwater permeable reaction walls

Embodiment Construction

[0076] Such as figure 1 As shown, the flow chart of the method for realizing the permeable reaction wall provided by the present invention, as can be seen from the figure, the method includes:

[0077] Excavation of underground slots whose depth reaches below the impermeable layer;

[0078] placing a prefabricated concrete frame device in the underground tank, the frame device comprising a plurality of frame units with preset seepage holes for water supply to flow out;

[0079] The prefabricated box structure is placed one by one in the frame unit of the outer frame device by using a special hoisting component. The box structure is equipped with a reaction medium for removing pollutant components in groundwater, and the box structure has a and outflow box preset seepage holes;

[0080] Among them, when the box structure is placed in the frame unit, a water stop device is also installed between the box structure and the frame unit, so as to block the water passing between the...

Abstract

The invention discloses a box structure of a permeable reaction wall, a permeable reaction wall and a realization method thereof. The method includes: digging an underground slot; placing an outer frame device in the underground slot, and the outer frame device includes a pre-installation system with water supply outflow; Multiple frame units with seepage holes; the box structure is placed in the frame unit by using a special hoisting component. The box structure is equipped with a reaction medium for removing pollutant components in groundwater, and the box structure has a supply Preset seepage holes for the inflow and outflow of groundwater; wherein, when the box structure is placed in the frame unit, a water stop device is placed between the box structure and the frame unit to block the connection between the two with the water stop device The water channels between them allow groundwater to flow through the preset seepage holes. The method of the present invention can realize the construction of groundwater permeable reaction walls in complex formation conditions or in relatively deep parts, and the box structure can realize underwater stacking, which is reusable and easy to replace, and the treatment is more environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to the field of groundwater and soil pollution remediation of environmental governance, in particular to a box structure of a permeable reaction wall, a permeable reaction wall and a realization method thereof. Background technique [0002] The groundwater permeable reaction wall is an in-situ treatment system for the remediation and treatment of groundwater and soil pollution. Specifically, after the groundwater in the soil passes through the permeable reaction wall, the heavy metals or organics in the groundwater will degrade and precipitate with the remediation medium in the reaction wall. A series of physical, chemical or biological actions such as adsorption and adsorption to achieve the restoration of groundwater to achieve a certain discharge index is an in-situ restoration method that uses natural or artificial groundwater hydraulic gradients to achieve. [0003] Currently publicly available practices on groundwater permea...
