Description
Technical field
The utility model belongs to the building foundation works.
Background technology
Building in the civil engineering work, harbour, bridge, the construction work in the inferior engineering all can relate to pile foundation engineering; Adopt the mud off instillation process to occupy very big proportion at China's pile foundation engineering; The use of mud is very lack of standardization always with processing in the pile foundation construction operation process; Especially this operation in the city has brought a lot of environmental problems; For example the careless disposal of discarded slurry has caused that the city river water system is silted up, city planting ductwork stops up, some row problems such as pollution of surrounding city environment, along with the raising of social civilization degree, and the reinforcement of the consciousness of environment protection and green construction; This problem has caused that also industry and government department pay close attention to, and some local governments have put into effect the special policies and regulations of mud.
Mud is the mixture that is formed by highly plastic clay or wilkinite and water mix, and as required, adds other material that improves mud property, like soda ash (Na
2CO
3), carboxymethyl cellulose sodium (CMC) etc., the annual mud amount that consumes of China is very big, according to the Wenzhou City, Zhejiang Province statistics, this city is annual in recent years to produce mud amount more than 100 ten thousand steres.This shows; In the face of big mud consumption problem like this; The problem of pendulum in face of us is exactly: the one, how to produce mud less; Reduce the processing costs of making slurry cost and engineering end back expense slurry of operation process, the 2nd, the treating method of seeking effective discarded slurry solves the urban environment problem that the careless disposal of present discarded slurry brings.
Summary of the invention
Be to overcome treatment of mud deficiency lack of standardization and technical in the existing engineering order of the utility model, provide a kind of less investment, the high engineering mud circulation of repayment to purify and dewatering system.
A kind of engineering mud circulation purifies and dewatering system, it is characterized in that: comprise and discharge mud channel, vibratory screening apparatus, mud settling sump, mud slurrying pond, mud storage pool, flocculation agent configuration-system, mud and water separating equipment; Mud and water separating equipment is provided with mud import, solid formation relief outlet and liquid phase thing relief outlet;
The pore forming process rig is discharged the mud channel below and is followed successively by vibratory screening apparatus and mud settling sump; Mud settling sump purifies pipeline connection mud slurrying pond through the overflow of band filtration unit; Mud settling sump connects the import of mud and water separating equipment through pipeline;
The flocculation agent configuration-system connects the import of mud and water separating equipment through pipeline;
Mud slurrying pond is provided with engineering mud delivery conduit, and mud slurrying pond connects the liquid phase thing relief outlet of mud and water separating equipment through the purification of drilling mud pipeline;
Mud reclamation pipeline when the mud storage pool is provided with concrete casting; The mud storage pool connects the import of mud and water separating equipment through pipeline; And the mud storage pool connects the liquid phase thing relief outlet of mud and water separating equipment through the purification of drilling mud pipeline;
At least each pipeline all is provided with a by-pass valve control on above-mentioned all pipelines.
Further, vibratory screening apparatus has adopted the orthoscopic vibratory screening apparatus.
Further, vibratory screening apparatus mesh size is set to 2mmx2mm.
The know-why of the utility model is following:
This project mud circulation purifies and dewatering system, is made up of first sludge-water separating system, middle sludge-water separating system, circularly purifying system and final sludge-water separating system.
First sludge-water separating system: when the stratum mud off operation that contains layer of sand, sandy gravel stratum, pebble bed; The mud that its pore forming process circulates out must contain oarse-grained material, in order to improve the efficient of mud-water separation, reduces the cost of mud-water separation; Recycle sand (gravel) material; Adopted vibration screening device in the system, width of mesh is controlled to be 2mm～3mm, and the material greater than mesh in the mud is separated from mouth of vibratory screening apparatus; On-the-spot directly use or transport outward, be drained into settling tank less than the slurry body of mesh.
Middle sludge-water separating system: along with increasing of settling tank slurry body; Be unlikely to mud settling sump is set up too big; Just must the slurry body of settling tank accumulation in time be separated; A kind of separating pathway is exactly a native system; Send into through steam piano and middle mud-water separation pipeline thereof and to carry out the centre mud-water separation in the centrifugal mud and water separating equipment; This moment, the system of centrifugal mud and water separating equipment should be at underdrive operating, and the solid phase slurry body of separating (water cut＜40%) uses conventional road vehicle to be transported to on-the-spot outer refuse tip or other places that needs, and the liquid phase slurry body of separating (purifying the somaplasm body) is transported to mud through recycling pipeline and makes the pond or purify the mud storage pool; Another approach is exactly to separate through following purification path road.
Circularly purifying system: in order to guarantee that the slurry body circularly purifying reaches maximum recycling in the operation process; System of the present invention has set up 2 road circularly purifyings; One the tunnel is exactly the liquid phase slurry body that above-mentioned middle sludge-water separating system is separated, and the characteristic of this process is exactly to adopt the system of centrifugal separating device, and the liquid phase slurry body that control is separated contains effective mud composition; Avoid the effective constituent in the mud is separated in the solid phase slurry body, do not have the effect of purification separation; Another road flows into the slurrying pond through overflow ducts (spout is provided with filtering net) exactly, and its effect one is to reclaim useful mud composition through filtering net, and another effect is exactly fast slurry body in the settling tank to be separated, and reduces the volume of settling tank.
Final sludge-water separating system: after this system was the pile foundation construction operation to a certain setting or scope, the mud in the storage pool no longer utilized the mud-water separation of carrying out.Mud in the storage pool is the effective constituent branch of mud basically; Promptly be the mixture that highly plastic clay or wilkinite and water mix form basically; It is characterized in that particle is more tiny; In order to reach requirement or the municipal emission standards that final liquid phase ejecta can reach on-the-spot Waste water utilization, adopted the flocculation agent configuration in the system, the flocculation agent that configures links to each other with Dehydrator for Slurry slurry body route through unidirectional transfer line; Make flocculation agent and particulate slurry body mix, create conditions for reaching the final real separation of muddy water.
Purification of drilling mud is carried out with dehydration simultaneously in purification of engineering mud circulation and the dewatering system solution construction operation process; Carrying out mud-water separation processing and mud circulation fast purifies; Reduce the mud sediment pool volume, reduce the waste of mud in the construction process, the water quality after the processing reaches water request for utilization in the scene; As flush the toilet, purposes such as depositing dust; The mud water cut of separating is lower than 40%, satisfies the requirement of outward transport fast of conventional road vehicle, for setting up slurry circularly purifying and the dewatering system that a cover is suitable in the working-yard.
