Description
Technical field
The present invention relates to a kind of sludge treatment technical field, the Apparatus and method for processed particularly to a kind of sludge solidification.
Background technology
Employing processes traditionally blowing-filling sludge and the method for processing foundation of auger ground mainly have draining concretion method, broken
Stone (sand) stake displacement method, Deep Mixing Method etc..Rubble (sand) stake displacement method and Deep Mixing Method construction costs all compare high
Expensive, be not suitable for large area and use.The processing method widely applied traditionally is draining concretion method: according to different loading draining shapes
Formula, discharging consolidation mainly has preloading, vacuum method, vacuum well-point dewatering method, vacuum electroosmosis precipitation to combine low-yield
Heavy-tamping method and low position vacuum preloading method.
Now two kinds of conventional traditional reclaimed ground treatment technologies are briefly outlined below:
1, vacuum method
Vacuum method is to set on sand bedding course and vertical drainage channel base, closing membrane is closed be reinforced soft
The weak soil body, and formation vacuum of bleeding so that in this sand bedding course and drainage channel, produce negative pressure.Consolidation is produced under this suction function
Pressure, makes soil body pore water discharge the foundation reinforcement method of soil solidifying continually.Vacuum method design refers to
Mark requires: the vacuum under vacuum preloading film is not less than 80KPa.Vacuum preloading applies in general to Muddy Bottoms soft clay foundation.Very
The empty general water discharge time of preconsolidation measure longer (about 90 180 days), disposes groundwork bearing capacity typically 60
80KPa.Technique of soft soil foundation treatment requires that blowing-filling sludge surface, through long period dry in the sun (6 December), can allow personnel and board-plugging device exist
On it, operation can go into operation, and need to buy technique sand bedding course thick more than 1 meter.Time length, low bearing capacity are its greatest problem, vacuum
Precompressed is finished groundwork bearing capacity and is not reached technology requirement, and constructing roadbed also need fills out 1 meter of thick mountain skin stone.
2, change and fill out displacement method
Cushion is Udoll part to be dug out, change fill out the low compressibility such as the bigger sand of intensity, crushed-gravel (mountain skin stone) dissipate
Body material, to improve foundation bearing capacity, to reduce settlement of foundation.The method is to dispose the relatively effective ways of shallow layer soft soil foundation.
Change the foundation bearing capacity after filling out typically at 120 200KPa.Change and fill out crowded silt and about need 23 meters of thick mountain skin rock layers, substantial amounts of mountain skin
Stone outward transport not only adds transport pressure, and the stone that cuts into a mountain brokenly obtains mountain skin stone and environment causes destruction greatly.Change to fill out and squeeze silt
The problem of method maximum is that freight volume is big and serious to environmental protection destruction.
In recent years, the Soft Soil formed along with substantial amounts of Marine shoal and dredging and reclamation urgently developed, and passed
The treatment of foundation with soft soil method of system, cycle long cost is high, and foundation bearing capacity is low, needs strange land roping lot of materials to replace, both broke
It is broken ecological environment, and poor durability, the contradiction between economic development and environment protection.
Summary of the invention
In order to solve problem of the prior art, the invention provides the Apparatus and method for that a kind of sludge solidification processes, use
The induration not only bearing strength that this Apparatus and method for is formed is high, and can stand the immersion of sea water or river lake water and wash away；Can
By mud and Extra-fine sand under und rained condition, original place consolidates.
The technical solution adopted in the present invention is as follows:
The equipment that a kind of sludge solidification processes, including firming agent storage tank and water tank, firming agent storage tank and water tank connect jointly
Having firming agent blender, described firming agent blender is by connecting sludge solidifying mixer with the pipeline of force (forcing) pump, described

Sludge solidifying mixer includes casing, is provided with rotary drum, arranges auger in described rotary drum in described casing
Mechanism, connects firming agent charging aperture by pipeline above described rotary drum, arranges firming agent discharging opening, institute below described rotary drum
The line shaft of the auger mechanism stated connects the rotation bar below firming agent discharging opening, described rotation after stretching out below casing
Bar connects has the three-jaw agitator with differential mechanism, described firming agent discharge outlet to arrange described pressure transducer.
A kind of method that sludge solidification processes, comprises the following steps:
A, first the water of firming agent Yu proper proportion is hybridly prepared into serosity；
B, again serosity is delivered on the sludge solidifying mixer of foundation construction position；
Serosity is directly injected in high-moisture percentage weak soil by C, sludge solidifying mixer, utilizes sludge solidification to stir simultaneously
Machine stirs the most on the spot and uniformly mixes with whole soft soil foundation layer to serosity, and consolidation forms induration.
Sludge solidifying mixer uses the construction method that excavator is equipped, and construction area is in excavator side, before excavator
Enter direction parallel with construction area, and spread out and put on sand material or mountain skin soil in complete region of just constructing as heap carrier layer, be bulldozed stone roller
As next step operation platform after pressure, constructing one by one, block-by-block advances.
Firming agent includes inorganic material cement, exciting agent and Organic substance surfactant.
Inorganic material cement is the mixture of one or more in cement, clinker, slag or flyash.
Exciting agent is the mixture of one or more in sulfide, alkali or inorganic salts.
Organic substance surfactant is dehydration flocculant, anion surfactant, nonionic surfactant or slow setting
The mixture of one or more in agent.

The technical scheme that the present invention provides has the benefit that
The present invention thoroughly solves conventional construction method long-term existence and indeterminable problem.Original position sludge material is entered
Row consolidation utilizes, it is not necessary to transport outward the landfill extruding of a large amount of mountains skin stone materials, and this is it is avoided that the stone that cuts into a mountain brokenly to the destruction of environment and squeezes
The secondary pollution that silt causes.Compared with using traditional cement material, Master Cost to reduce by more than 70%.
Owing to firming agent consolidation effect is fast, therefore the surface that can realize just having stirred consolidation can be as next constructing operation
Platform, it is achieved that in the ground continuous construction of mud, accelerate the speed of application of silt consolidation, greatly reduce and be constructed into
This.
Mud stirring consolidation ground bearing pressure improves rapidly, shortens the waiting time for building thereon.With traditional true
As a example by empty precompressed, this waiting time is about in the 6-12 month, and the technology of the present invention only has 1-3 month.
