Embodiment 1

[0095] Such as Figure 10 As shown, it is a top view of this embodiment after the water stop device 100 is installed between adjacent frame units. It can be seen from the figure that the water stop device 100 of this embodiment includes a water stop unit 10, and the water stop unit 10 is placed on the Between two adjacent frame units ( Figure 10 Only two frame units are shown in the figure, and in actual application, multiple frame units may be included, and the water-tight unit 10 of this embodiment is arranged between every two adjacent frame units, wherein the frame unit Prefabricated concrete structures.

[0096] Among them, the water-stop unit 10 of this embodiment is made of elastic materials, such as EPDM rubber, so that the water-stop unit 10 has good elasticity, and can adapt to the adjacent frame unit of the groundwater reaction wall within a certain range. The gap between them plays a good role in blocking the flow of polluted water. In addition, EPDM rubber has ...

Embodiment 2

[0104] The water-stop unit adopted by the water-stop device 100 of this embodiment is as follows: image 3 The structure shown is basically the same as that of Embodiment 1. When it is placed between two adjacent frame units, the arrangement is the same as that of Embodiment 1. The difference from the water-stop unit of Embodiment 1 That is, the water-stop unit of this embodiment also has a third arc-shaped surface c and a tail ridge 2, and the first and third arc-shaped surfaces of the convex body serve as the water-facing surfaces.

[0105] In the following, only the structural differences between the water stop unit of the present embodiment and the first embodiment will be described in detail.

[0106] Since the first arc-shaped surface a of the convex body of the water-stop unit is used as the water-facing surface, the polluted water flowing in will form a greater impact on the water-stop unit. In order to prevent the first arc-shaped surface a from contacting the water-s...

Embodiment 3

[0110] The water stop unit for the water stop device 100 of this embodiment adopts the following Figure 4 The structure shown is basically the same as that of Embodiment 2, and when it is placed between two adjacent frame units, it is the same as that of Embodiment 2, that is, the first arc-shaped surface of the convex body, The third arc-shaped surface is used as the water-facing surface, and the difference from the water-stop unit of Embodiment 2 is that the water-stop unit of this embodiment also has a water-stop deformation hole 5 .

[0111] In the following, only the structural differences between the water stop unit of the present embodiment and the second embodiment will be described in detail.

[0112] Such as Figure 4 As shown, in this embodiment, a water-stop deformation hole 5 is provided near the water-stop fixing part 3 on the first arc-shaped surface a of the convex part of the water-stop unit. Preferably, the water-stop deformation hole 5 is set on the first ...

Abstract

The invention discloses a method for realizing a prefabricated concrete permeable reactive wall frame body and an outer frame device. The method comprises the following steps: an underground slotted holes are excavated; and the outer frame device formed by prefabricating concrete is arranged in the underground slotted holes, the outer frame device comprises one or more layers of frame body units,and each layer of frame body unit comprises a plurality of frame body units with preset seepage holes for water to flow out; a water stopping device capable of blocking a water passing channel betweenthe adjacent frame body units so as to enable water flow to flow through the preset seepage holes is arranged between the adjacent frame body units, so that the prefabricated concrete permeable reactive wall frame body is formed through the outer frame device and the water stopping device; the frame body unit is internally provided with one or more lattices which are arranged at intervals, and reaction media used for treating underground polluted water are arranged in the lattices. By means of the method, the underground water permeable reactive wall can be constructed under complex stratum conditions or at deep positions, the underground water permeable reactive wall can be repaired easily, and the reactive wall can be repeatedly used and is high in interchangeability and low in manufacturing and repairing cost.

Description

technical field [0001] The invention relates to the field of groundwater and soil pollution restoration and treatment of environmental governance, in particular to a method for realizing a frame of a prefabricated concrete permeable reaction wall and an outer frame device 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 pract...
