Embankment section.
Compared with prior art, it is an advantage of the current invention that: the silt soil substitution of resources routine using Coastal beach to enrich
Sand as embankment filling material, the construction equipment utilizing the present invention to provide is delivered to after it being stirred with curing agent
Bag forms cofferdam, and the construction equipment collection that the present invention provides fetches earth, stirs, carries, charges whole process by once,
Efficiency of construction can greatly be improved, and save a large amount of engineering cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the construction equipment of mud filling bag embankment in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
The construction equipment of mud filling bag embankment as shown in Figure 1, it includes
Hull 1；
The chain-bucket dredging plant 2 being arranged on hull, for directly taking seabed original state mud；
Pulverizer 3, is arranged on hull, and the output of chain-bucket dredging plant is connected with the entrance of pulverizer, for right
Seabed original state mud crushes；
Mixer 4, is arranged on hull, and the outlet of pulverizer is connected with the entrance of mixer, for the silt after crushing
Mud is stirred；
Poly-hopper dredger 5, is arranged on hull, is positioned at below mixer, and the outlet of mixer is connected with poly-hopper dredger by chute；
Pulp pump 6, is arranged on hull, and the entrance of Pulp pump connects with poly-hopper dredger；
Curing agent adds and conveying device 7, for adding curing agent in mud；
Mixing plant 8, slurry delivery side of pump and curing agent add and the outlet of conveying device all connects with mixing plant, mud
Abundant mix is carried out to uniformly with curing agent in this mixing plant；
Slush pump 9, the entrance of slush pump connects with mixing plant, and mud delivery side of pump connects with the bag completed in advance.
In order to overcome the drawback that the moisture content that fetches earth in conventional equipment is big, soil extracting efficiency is low, the present invention directly uses chain-bucket
Dredger transformation form, hull 1 is the hull of bucket dredge, then pulverizer 3, mixer 4, poly-hopper dredger 5,
Pulp pump 6 is directly installed on hull 1；Chain-bucket dredging plant 2 uses existing conventional structure, directly takes seabed former
Shape soil, fetch earth degree of depth 6m, full-load draft 1m, and in order to adapt to the power match requirement of whole system, chain bucket rotating speed is adopted
With stepless speed regulation scheme (rotating speed can arbitrarily regulate from 0 to setting value), soil extracting efficiency is up to 200m3/h。
In order to make mud slurry matter uniform, mud is stable, first the block undisturbed soil taken is carried out physical treatment, to reach
The requirement of conveying；Here physical processing apparatus is by including that pulverizer and pusher biaxial rneader form, and pulverizer comprises
Three groups of crushing shafts, every crushing shaft is provided with free end towards different blade, and often the spacing between group rotating shaft is 1.5m.
Pusher biaxial rneader sets two helical axis, two helical axis spacing 90cm, every helical axis height 80cm, uses
Right-handed screw formula structure.Owing to muck soil clay content is high, in order to effectively mud original soil to be carried out broken stirring, become silted up
Mud original soil sets the poly-hopper dredger of rectangle of a 2m*2m after double-axle stirrer, adds two groups of crushing shafts in poly-hopper dredger again.Become silted up
Mud induction system uses high-power Pulp pump, lift 52m, output pressure 1Mpa；Use between Pulp pump and poly-hopper dredger
Caliber is that the pipeline of 250mm is connected, and in order to improve fed distance, can in position add small-sized relay pump.
Curing agent adds and conveying device includes curing agent automatic feeding device and curing agent conveying device, and curing agent divides pulvis
And liquid agent, therefore, curing agent automatic feeding device is the spiral continuous metering for controlling fixed curing agent addition
Device or for controlling the flow pump of liquid curing-agent addition, curing agent conveying device uses conventional plunger pump.
For making curing agent and the abundant mix of mud, stable performance, a mixing plant, mud and solidification are set near hull
Agent is delivered in this mixing plant, charges to bag after stirring.
The running technology scheme of whole construction equipment is: chain-bucket dredging plant 2 first carries out taking seabed original state mud, sea
End original state mud is discharged into pulverizer 3 and crushes, and is stirred subsequently into mixer 4, then enters poly-along chute 10
In hopper dredger 5, setting mud secondary crushing device in poly-hopper dredger 5, the mud after crushing enters Pulp pump 6, then by pipe
Road 11 is delivered in neighbouring mixing plant 8, and curing agent is also delivered in this mixing plant 8 by plunger displacement pump simultaneously, mud and
Curing agent action of forced stirring uniformly after be delivered in bag, the power of whole system is 200kw, charge efficiency up to
170-180m3/ h, fully meets practice of construction needs.
The construction method of the mud filling bag embankment that the construction equipment of the mud filling bag embankment of employing said structure is carried out is:
Before construction, taking mud scope according to the position of embankment is selected, size and drinking water further according to hull require excavation ship nest,
Moisturizing passage, the barrier of cleaning borrow areas scope are set；
After the measured unwrapping wire in embankment position, manually carry out the laying of bag, during construction, take silt depending on chain-bucket dredging plant
The water content situation of mud, carries out the moisturizing mobility with raising mud before mud enters pulverizer, and mud is through disintegrating machine
Enter poly-hopper dredger after broken, mixer stirring, flow to mixing plant by Pulp pump the most again, curing agent interpolation simultaneously and
Conveying device carries curing agent toward mixing plant, is filled by slush pump after in mixing plant, mud is sufficiently stirred for curing agent
Fill to bag；
During bag charges, change in time and charge a mouthful position, be aided with simultaneously and manually trample bag leveling, it is to avoid locally
Too high phenomenon occurs, and bag charges THICKNESS CONTROL at 60cm, and control errors is at 2cm, in order to accelerate whole bag
Solidification effect, arranges outside the thin mud of pools zone discharged bag by temporary drainage mouth in time, thickness to be charged on bag
Meet after requiring, carry out charging of next bag；Because of filling in bag be slurry mixture, in work progress, hold
Easily sliding, therefore need compartment to construct, i.e. next bag construction location is the position after sky opens a bag, then fills
Fill, but ensure there is the overlap joint not less than 1m between each bag；
Lower pocket charge complete after, then upper strata bag is progressively charged superposition, charges and complete stick to bag table
The mud giant in face cleans up, and reserves the discharging consolidation time between layers simultaneously, ultimately forms design requirement
Embankment section.
