It is provided with reinforcement isolation barrier；The groundwater monitoring well is arranged on the reinforcement isolation barrier and enclosed with the vertical isolation barrier
Into region inside.
The vertical isolation barrier is any in cement mixing method, steel sheet-pile wall, high-pressure rotary-spray piling wall or flexible membrane
It is a kind of；The bottom buried depth of the vertical isolation barrier is more than the distributed depth of the Polluted area internal contamination thing.
The reinforcement isolation barrier is any in cement mixing method, steel sheet-pile wall, high-pressure rotary-spray piling wall or flexible membrane
It is a kind of；The bottom buried depth for strengthening isolation barrier is more than the distributed depth of the Polluted area internal contamination thing.
The groundwater monitoring well is connected with aspirator and injection device.
The groundwater monitoring well includes well casing and the screen pipe installed in the well casing bottom.
The utility model has the advantages that, the pollutant that vertical isolation barrier can effectively isolate inside Polluted area；Plus
Strong isolation barrier combination groundwater monitoring well can further enhance the reliability of vertical isolation barrier；Groundwater monitoring well can be with
The effectively whether contaminated thing of monitoring vertical isolation barrier punctures, and carries out repairing and treating to puncture place.
Brief description of the drawings
Fig. 1 is vertical isolation barrier and the top view of reinforcement isolation barrier in the utility model；
Fig. 2 is groundwater monitoring well sectional view in the utility model.
Embodiment
Feature of the present utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with accompanying drawing
It is bright, in order to the understanding of technical staff of the same trade：
Mark 1-6 is respectively in such as Fig. 1-2, figure：Vertical isolation barrier 1, groundwater monitoring well 2, Polluted area 3, reinforcement
Isolation barrier 4, well casing 5, screen pipe 6.
Embodiment：As shown in Figure 1-2, the present embodiment is specifically related to a kind of contaminated site vertical isolation repair system, and it is wrapped
Include vertical isolation barrier 1 and groundwater monitoring well 2；Vertical isolation barrier 1 is circumferentially positioned in the soil layer in the outside of Polluted area 3
Portion；Major pollutants inside Polluted area 3 are insecticide, bactericide, herbicide, toluene, anhydrous isopropyl alcohol, dichloromethane,
Methanol, mixed ester etc..Found by Investigation on Pollution, the pollutant distribution depth inside Polluted area 3 is maximum in 8m or so
Depth of investigation is in 14m-18m or so.
As shown in figure 1, vertical isolation barrier 1 can be cement mixing method, steel sheet-pile wall, high-pressure rotary-spray piling wall or flexibility
Any one in film, the bottom buried depth of vertical isolation barrier 1 is more than the distributed depth of the internal contamination thing of Polluted area 3；At this
In embodiment, the use dual spindle soil-cement mixing pile of vertical isolation barrier 1, stake footpath φ 700 mm, adjacent studs lap of splice 200mm,
Cement mixed weight 15%, cement preferably uses strength grade P.0 42.5 grades of Portland cement, the depth of vertical isolation barrier 1
For 15m.
As shown in figure 1, when the periphery of Polluted area 3 has important Architectural Equipment or during i.e. by building constructions, can hang down
The outside of the straight relevant position of isolation barrier 1, which is set, strengthens isolation barrier 4；Strengthen isolation barrier 4 to be arranged on inside soil layer；Underground water
Monitoring well 2 is arranged on vertical isolation barrier 1 with strengthening inside the region that isolation barrier 4 is surrounded；In the present embodiment, Polluted area
3 east side is river, and river east side is proposed to set primary school, to prevent the construction of the large area earthing of Polluted area 3 to place east side river
Adversely affect and the effective hydraulic connection in barrier Polluted area 3 and river course, vertical isolation barrier 1 close to river course side
Side, which is set, strengthens isolation barrier 4, and vertical isolation barrier 1 and the spacing strengthened between isolation barrier 4 are 2m, and remaining parameter is ibid.
Vertical isolation barrier 1 is laid with groundwater monitoring well 2 with strengthening in the region that encloses of isolation barrier 4, well spacing 40m, well depth and
The greatest contamination depth that filtering pipeline section depth is put according to well location is determined.
