Specific embodiment
The utility model is described further with reference to embodiments.
As Figure 1-Figure 4, a kind of permeable reaction wall for Soft Soil Layer, the Larsen steel sheet pile enclosing including two sides
1 and several reaction material packets 2 between the two Larsen steel sheet pile enclosings 1；Larsen steel sheet pile enclosing 1 includes several sides
The web of the aperture Larsen steel sheet pile 1.1 that side successively connects, each aperture Larsen steel sheet pile 1.1 is equipped with several through-hole 1.1.1；
Reaction material packet 2 includes the reaction wood bed of material 2.2 in the nylon wire 2.1 and nylon wire 2.1 of outer layer；Reaction material packet 2 is placed in two
Between the through-hole 1.1.1 of the Larsen steel sheet pile enclosing 1.Through-hole 1.1.1 is square hole.Several through-hole 1.1.1 are in several
Group equilateral triangle distribution；1.1 outer surface of aperture Larsen steel sheet pile is equipped with erosion resistant coating；Reaction material packet 2 is obliquely installed described in two
Between Larsen steel sheet pile enclosing 1 and slope aspect is opposite with water (flow) direction.
The principles of the present invention and application are as follows:
As shown in figure 5, underground water region soil property is followed successively by plain fill layer 6, silt soil strata 5 and clay layer 4 from top to bottom,
The downstream in underground water pollution region is arranged in permeable reaction wall (PRB) described in the utility model, perpendicular to the stream of underground water
To Larsen steel sheet pile enclosing 1 is embedded in the clay layer 4 of 5 lower section of underground water region silt soil strata, guarantees the stabilization of groove, can
The top of permeable coefficient tensor is covered by clay layer 4, prevents surface water from penetrating into, and the underground water 3 that contaminated source 7 is polluted passes through institute
State permeable reaction wall, purification of ground water.
Through-hole 1.1.1 on aperture Larsen steel sheet pile 1.1 is the circulation in order to guarantee underground water 3.Through-hole 1.1.1 is rectangular
Hole is not easy to plug relative to round hole, and square hole is distributed using equilateral triangle, and percent opening is not less than 2%, guarantees that underground water 3 flows
Freely, by while guarantee 1.1 material of aperture Larsen steel sheet pile intensity have enough stability.Aperture Larsen steel sheet pile 1.1
Outer surface is equipped with erosion resistant coating, guarantees that the length of service meets the requirement of the PRB length of service.
2.1 encapsulation reaction material layer 2.2 of nylon wire, first is that in order to guarantee the reaction wood bed of material 2.2 not by groundwater flow band
It walks, second is that the recycling and replacement of the reaction wood bed of material 2.2 for convenience.The reaction wood bed of material 2.2 generally comprises Zero-valent Iron, zeolite, work
Property charcoal etc., general 80 mesh of partial size~200 mesh, the type selecting and proportion of the reaction wood bed of material 2.2 are determined according to laboratory test, pollute species
Class and concentration difference, the reaction wood bed of material 2.2 and proportion be not also identical.2.1 mesh partial size of nylon wire is than 2.2 partial size of the reaction wood bed of material
It is small, the nylon wire 2.1 of 60 mesh meshes can be selected.The reaction wood bed of material 2.2 reaches saturation in absorption, and activity disappears, porosity becomes
When very little, reaction material packet 2 can be hung out out of reaction wall by crane, then new reaction material packet 2 is lifted into anti-
Answer wall.The PRB entirety infiltration coefficient that reaction material packet 2 and two sides Larsen steel sheet pile enclosing 1 are constituted should be greater than silt soil strata 5
Twice of infiltration coefficient, to guarantee that groundwater flow is unimpeded.
2.1 encapsulation reaction material layer 2.2 of nylon wire forms reaction material packet 2, and reaction material packet 2 is designed as long × height=1
× 0.5m, width take PRB groove width, facilitate the recycling and replacement of reaction material packet 2.When reaction material packet 2 is filled, on section
With horizontal plane at about 10 ° of angles, and slope aspect and 3 water (flow) direction of underground water are on the contrary, prevent underground water 3 among reaction material packet 2
Around flowing through, do not come into full contact with reaction material；2 upper layer and lower layer of reaction material packet staggeredly be laid with, guarantee underground water 3 in pollutant with
Reaction material 2.2 comes into full contact with.
Certainly, the above is only the specific application examples of the utility model, do not constitute and appoint to the protection scope of the utility model
What is limited.In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent substitution or equivalent transformation
The technical solution of formation, all fall within the utility model it is claimed within the scope of.
