Description
Technical field
After a kind of dumping mud treatment and reuse method, more particularly to a kind of discarded slurry dewater treatment
The method that dregs, drainage recycle.
Background technology
Remaining slurry and useless slurry are always to perplex the significant technology issues of underground engineering construction, and existing processing mode is to use tank car
Mud, which is transported to countryside, makes its natural desiccation, and the original backwardness of this processing mode, efficiency are low, costly, Chang Yin in transportation
The leakage of mud is spilt and pollutes the appearance of the city.Although various regions government has put into effect substantial amounts of policies and regulations, in huge economic profit incentive
Under, supervision leak is taken advantage of in some construction sites, and construction slurry is stolen and arranges disorderly row, very serious consequence is caused therefore, is engineering
Mud find economic and environment-friendly processing mode as social development there is an urgent need to.
Existing discarded slurry solidification processing method is handled mainly for the separation of solid and liquid of discarded slurry, is less focused on through dividing
Consider the dewater treatment of discarded slurry and the recycling in later stage from rear dregs and filter water reuse, the present invention, be
More preferable harmless treatment discarded slurry provides thinking.
The content of the invention
The present invention is to solve in underground engineering construction the problem of caused a large amount of discarded slurry environmental pollution, and provide
A kind of discarded slurry curing process and reuse method.
To achieve the above object, the technical scheme is that：
A kind of discarded slurry curing process and reuse method, are comprised the concrete steps that：
（1）Caused discarded slurry in construction is collected；
（2）Useless slurry sampling to collection carries out performance detection；
（3）If useless slurry is unsatisfactory for the performance requirement of dehydration equipment and through the economy ratio with directly carrying out mechanical dehydration processing cost
After relatively, add additive and carry out property regulation, the useless slurry is met dehydration equipment requirement；
（4）The useless slurry input dehydration equipment for meeting dehydration equipment requirement is subjected to separation of solid and liquid processing；
（5）The dregs after separation is collected, adds curing agent, carries out consolidation curing process, formation has some strength and particularity
The material of energy；
（6）The drainage after separation is collected, and carries out performance detection；
（7）Additive is added in the drainage for being unsatisfactory for recirculated water index request to be handled, and the drainage is met that recirculated water refers to
Mark requires；
（8）The drainage for meeting recirculated water requirement is delivered to slurrying area and carries out new slurry mixing.
Step（2）Described in performance detection index be the viscosity of useless slurry, the rheological characteristic of proportion, sand coarse aggregate ratio and dynamic and static shear force
Can index.
The described useless slurry for being unsatisfactory for dehydration equipment performance requirement needs to carry out performance inspection again after additive treating is added
Survey, ensure that the mud of input dehydration equipment meets equipment requirement.
Described dehydration equipment is to utilize physical method, the equipment that mud can be carried out to separation of solid and liquid.
The material that dregs after described solidification consolidation process is formed be with crushing resistance, impermeability, chemical resistance of concrete,
The material of water resistance or frost resistance.
The described index examined to recirculated water prepares the requirement of mud to determine needed for.
The beneficial effects of the invention are as follows：The present invention a large amount of discarded slurries caused by solve underground engineering construction are stacked, mud
Starching natural sedimentation, time-consuming and useless slurry outward transport cost is high, pollutes the problems such as big and proposes a solution, solid-liquid is carried out to discarded slurry
Recycled after being handled respectively dregs and drainage after separation, improve mud effective utilization, greatly reduce discarded slurry pollution.
Brief description of the drawings
Fig. 1 is the discarded slurry curing process and reuse method flow chart of the present invention.
Embodiment
With reference to specific implementation example, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate this
Invention rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, this area skill
Art personnel can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims institute
The scope of restriction.
A large amount of discarded slurries will be produced during underground engineering construction, it is higher and to environment that conventional outward transport focuses on cost
Pollute, using the discarded slurry curing process and reuse method of the present invention, as shown in figure 1, consolidating to discarded slurry
Change processing and recycling processing, specific method and step are as follows：
（1）Caused discarded slurry in construction is collected, discarded slurry refers to what should be discarded as defined in each job specfication
Mud；
（2）Useless slurry sampling to collection carries out performance detection；
（3）If useless slurry is unsatisfactory for the performance requirement of dehydration equipment and through the economy ratio with directly carrying out mechanical dehydration processing cost
After relatively, add additive and carry out property regulation, the useless slurry is met dehydration equipment requirement；
（4）The useless slurry input dehydration equipment of dehydration equipment requirement is subjected to separation of solid and liquid processing；
（5）The dregs after separation is collected, adds curing agent, carries out consolidation curing process, formation has some strength and particularity
The material of energy；
（6）The drainage after separation is collected, and carries out performance detection；
（7）Additive is added in the drainage for being unsatisfactory for recirculated water index request to be handled, and the drainage is met that recirculated water refers to
Mark requires；
（8）The drainage for meeting recirculated water requirement is delivered to slurrying area and carries out new slurry mixing.
Step（2）Described in performance detection index be the viscosity of useless slurry, the rheological characteristic of proportion, sand coarse aggregate ratio and dynamic and static shear force
Can index.
Be unsatisfactory for the useless slurry of dehydration equipment performance requirement needs to carry out performance detection again after additive treating is added, and ensures
The mud of input dehydration equipment meets equipment requirement.Dehydration equipment is to utilize physical method, mud can be carried out into separation of solid and liquid
Equipment.The material that is formed of dregs after solidification consolidation process be with crushing resistance, impermeability, chemical resistance of concrete, water resistance or
The material of frost resistance.The index examined to recirculated water prepares the requirement of mud to determine needed for.
Application implementation example of the present invention;
Certain produces a large amount of discarded slurries during being located at the underground engineering construction of business district, because of construction site and Chinese Ministry of Environmental Protection's thresholding
System, discarded slurry can only transport at night, and useless slurry outward transport cost is high, significantly impacts construction speed and cost.
Using the present invention to caused by the engineering discarded slurry carry out curing process, by the dregs after separation of solid and liquid concentrate into
Row consolidation curing process, is made supporting course, soundproof wall coating and inserts of highway subgrade etc., and drainage then recycling
The mixing newly starched, the pollution to environment in the cost and transportation of outward transport is not only saved, while create recycling
Value, the construction cost greatly reduced, and bring economic benefit.
