A kind of original position vertically isolates preparation facilitiess and the preparation method of Engineering Barrier Materials.
Background technology
In recent years, due to the great demand of national development strategy, economic restructuring, a large amount of industrial undertakings close down, move,
Leave lower a large amount of industrial pollution place.Left industrial pollution place just must can carry out follow-up secondary development through processing.Another
Aspect, China's solid waste storage is increased dramatically, and deposits in Solid Waste Landfills by land-fill method in a large number.Gu but
Body Landfills leachate has the potential risk infiltrating polluted underground water.Vertical isolation engineering barrier is that one kind can have
The safeguard procedures that effect retardance pollutant migrate in subsoil water, can be used in combination with other soil and groundwater remediation measure, and
Realize reducing the risk of secondary pollution.
It is a kind of economically viable vertical isolation engineering barrier type that soil-swelling soil series vertically isolates engineering barrier, has
Anti-permeability performance is better than that traditional Soil-cement continuous process barrier, engineering barrier body material diffusion coefficient be low, low engineering cost
Advantage.The construction technology at present vertically isolating engineering barrier in soil-swelling soil series include excavating-become slot type construction technology and
Original position thin-walled vertical barrier construction method based on box composite steel plate pile.Excavate-become slot type construction technology to pass through to excavate soil layer shape
Become the groove of certain depth, be injected simultaneously into bentonite slurry and carry out mud off；Stir in situ bentonite and excavated in-situ soil
Preparation is vertical to isolate Engineering Barrier Materials, and isolates Engineering Barrier Materials moisture content by bentonite slurry regulation is vertical；By institute
The vertical Engineering Barrier Materials of isolating of preparation are backfilled to excavation groove, form engineering barrier.Original position based on box composite steel plate pile
Thin-walled is vertically isolated engineering barrier construction and is passed through prefabricated components, controls thickness and the engineering screen of vertical isolation engineering barrier of being constructed
The overall homogeneity of barrier material；Vertical isolation Engineering Barrier Materials preparation method is consistent with excavating-becoming slot type construction technology, and leads to
Cross pumping or reperfusion mode injection prefabricated components, form vertical isolation engineering barrier.Two methods are real in construction technology itself
Existing construction process optimization and improvement, realize a certain degree of mechanical automation on construction mould, device and equipment.
Existing construction technology still cannot effectively solving soil-swelling soil series vertically isolate Engineering Barrier Materials in situ, efficiently,
The uniformly construction technology defect of preparation.Conventional art carries out mix using high-front shovel, and stirring efficiency is low, in-situ soil with swollen
The uniformity coefficient that profit soil and improved materials carry out mix is low, and the quality control difficulty of moisture content and bentonite volume is big, causes work
Uniformity is greatly reduced journey barrier material on the whole, easily forms local defect.Additionally, using necessary during tradition stirring construction technology
Take large-area construction place, and affect surrounding enviroment；It is perpendicular when punishing the urban industry contaminated site that place is limited in scope
Place space is caused to limit to isolation construction.Using the stirring constructing device of cement material or cement material and mixing with soil material,
For following problem will be run into when preparing vertical isolation Engineering Barrier Materials：(1) because device is with drum-type stirring, lead to appearance
Bentonite slurry sinks to the bottom phenomenon, and bentonite slurry cannot play and adjust the vertical effect isolating Engineering Barrier Materials moisture content；(2)
Mixing drum or stirring vane are pressed one-directional rotation and are stirred, and cause to stir uneven；(3) drum-type stirring cylinder or other agitating devices be no
Method crushing gravel and bulk soil, lead to prepared vertical isolation Engineering Barrier Materials grain composition poor, are easily formed defective perpendicular
To isolation engineering barrier；(4) Engineering Barrier Materials are easy to stick invests mixing drum barrel for vertical isolation, cause waste of material.The opposing party
Face, the original position strange land curing technology of urban industry contaminated site reaches its maturity, but the Polluted Soil of cured process presence carrying hardly possible,
The problems such as stacking limited space, secondary utilization degree of recognition are low.How effective exploitation is subject to using original position strange land solidification Polluted Soil
Environmental geotechnical and soil remediation industry extensive concern, its engineering secondary using needing to be excavated further.
