Description
Technical field
The present invention relates to a kind of firming agent, particularly to a kind of sludge composite curing agent.
Background technology
Traditionally draining concretion method, broken is mainly had using the method for processing foundation of the blowing-filling sludge processing and auger ground
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 adopt.The processing method traditionally widely applied is draining concretion method: according to different loading draining shapes
Formula, it is low-yield that discharging consolidation mainly has preloading, vacuum method, vacuum well-point dewatering method, vacuum electroosmosis precipitation to combine
Heavy-tamping method and low position vacuum preloading method.
Now conventional to two kinds traditional reclaimed ground treatment technology is briefly outlined below:
1st, vacuum method
Vacuum method is on setting sand bedding course and vertical drainage channel base, closing membrane is closed be reinforced soft
The weak soil body, and it is evacuated formation vacuum so that producing negative pressure in this sand bedding course and drainage channel.Consolidation is produced under this suction function
Pressure, makes soil body pore water continually discharge to complete the foundation reinforcement method of soil solidifying.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 general water discharge time of empty preconsolidation measure is longer (90 180 days about), disposes groundwork bearing capacity typically 60
80kpa.Technique of soft soil foundation treatment requires blowing-filling sludge surface through long period dry in the sun (6 December), and personnel and board-plugging device can be allowed to exist
Operation can go into operation thereon, and need to buy thick technique sand bedding course more than 1 meter.Time length, low bearing capacity are its greatest problem, vacuum
Precompressed is finished groundwork bearing capacity and is not reached technical requirements, constructing roadbed also needs to fill out 1 meter of thick mountain skin stone.
2nd, change and fill out displacement method
Cushion is to dig out Udoll part, change fill out the low compressibilities such as the larger 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 in 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 increased transport pressure, and the stone acquisition mountain skin stone that cuts into a mountain brokenly causes to environment greatly to destroy.Change to fill out and squeeze silt
The maximum problem of method is that freight volume is big and serious to environmental protection destruction.
In recent years, the Soft Soil being formed with substantial amounts of Marine shoal and dredging and reclamation urgently develops, and passes
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 enter line replacement, both broke
It is broken ecological environment, and poor durability, the contradiction between economic development and environment protection.
Stablizing silt soil using sludge curing agent is the hot technology in silt soil Treatment process then, this mud penus
In special soil, there is higher moisture content and organic matter.The sludge treatment solidification of China is still in the starting stage.
Content of the invention
In order to solve problem of the prior art, the invention provides a kind of sludge composite curing agent, it mainly acts on silt
Mud, can substitute vacuum preloading+change the traditional construction technique filling out mountain stone skin+strong rammer, can be used for highway, town road, port
Mouth stockyard and the basement process of various building yard.
The technical solution adopted in the present invention is as follows:
A kind of sludge composite curing agent, including the component of following mass parts: the inorganic material cement of 20-50 mass parts,
The Organic substance surfactant of the exciting agent of 2-5 mass parts and 2-10 mass parts.
Inorganic material cement is the mixture of one or more of cement, clinker, slag or flyash.
Exciting agent is the mixture of one or more of sulfide, alkali or inorganic salts.
Organic substance surfactant is dehydration flocculant, anion surfactant, nonionic surfactant or slow setting
The mixture of one or more of agent.
Dehydration flocculant is polyacrylamide.
Anion surfactant is soap, sodium alkyl sulfonate, sodium alklyarylsulfonate, alkyl sodium sulfate, secondary alkyl sulfide
The mixture of one or more of sour sodium.
Nonionic surfactant is fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, aliphatic acid polyethenoxy, fat
Fat amine polyoxyethylene ether, alkylolamideses polyoxyethylene ether, one or more of Block polyoxyethylene-polyethenoxy ether mixed
Compound.
The sludge composite curing agent of the present invention, its Organic substance surfactant plays surface-active action and deferred action,
Make inorganic material cement be more easy to enter inside soil particle, so that ion-exchange reactionss is carried out rapidly, thoroughly, adjust simultaneously
The time delay of firming agent.
The sludge composite curing agent of the present invention can carry out the sludge solidification of road foundation, and its cost of building the road not only can drop
Low 20%-50%, and the combination property (durability and stability) of roadbed is also significantly better than conventional sandstone roadbed, especially plate body
Property good, intensity is high.
The mud of dredging desilting can also be converted into earth working material by sludge composite curing agent, can according to moisture content not
With, this firming agent and mud are stirred and spreads out and puts on compacting, make induration short-term consolidation and sclerosis, both can build park, and make island, and
Can build the road sill, completely can be from sea water, the immersion of fresh water, and its later strength can more and more higher.
The technical scheme that the present invention provides has the benefit that
1st, improve comprcssive strength, the unconfined compressive strength ratio of the silt consolidation body that sludge composite curing agent obtains is individually general
The unconfined compressive strength of the induration of logical portland cement improves nearly 300%, and the prolongation with curing time, its consolidation
The unconfined compressive strength of body is still stepping up.
2nd, improve water stability, due to its distinctive mechanism of action, the solidification to mud is permanent, city is tested
Test specimen and the same conditional maintenance test specimen carry out immersion observation, no dissipate solution phenomenon, and intensity free of losses.
