Abstract
The invention relates to a washing device for milling wheels of a slot milling machine. The washing device comprises a slurry injection pipe, a nozzle, a slurry pipe and a connector. The nozzle is arranged above the milling wheels in the rotating direction of the milling wheels, connected with the slurry pipe through the slurry injection pipe and the connector, and used for washing the milling wheels of the slot milling machine directly at the slot bottom of an underground wall to reduce the long-time working temperature of the milling wheels and improve slot bottom slurry parameters. Fresh slurry or clean water is pressed in from the slurry pipe and then sprayed out through the nozzle to wash the milling wheels directly or wash the milling wheels in the rotating direction of the milling wheels, clods and fine sand on the peripheries of the milling wheels are driven to be sucked away together through a slurry return port from the lower portions of the milling wheels, the working temperature of the milling wheels can be reduced while the problem that the specific gravity of slot bottom slurry is large is relieved, slot bottom slurry can be replaced more effectively, it is avoided that as clods generated by milling at the peripheries of the milling wheels adhere, cake and tightly wrap the milling wheels due to the high temperature, working cannot be carried out, and the milling wheels need to be lifted to the ground and manually washed to remove clods, working efficiency can be greatly improved, and the risk of slot wall unstability caused by repeated lifting and washing of the milling wheels wrapped with silt is lowered.
Description
Technical field
The present invention relates to a kind of flusher of slotter milling wheel, construction in especially a kind of clay geology for ultra-deep
Milling wheel bottom land flusher.
Background technology
With the continuous development in city, the exploitation of the underground space are increasingly subject to people's attention.In underground engineering
Construction field, excavation of foundation pit depth is more and more deeper, and form of going along with sb. to guard him adopts the more and more of diaphram wall.But ultra-deep stratum
In, equipment sinks and the path of lifting is longer, and the used time is also longer, for improving efficiency of construction, ensureing that groove milling perpendicularity and cell wall are steady
Fixed it is therefore highly desirable that groove milling function one milling is on earth or as far as possible few is lifted out ground, reduce the groove section engineering time and to groove section
Repeatedly disturbance.But the increase with depth, bottom land mud balance is increasing, and mud sediment carrying capacity degradation, at milling wheel
Mud tube is only capable of drawing the mud on milling wheel top, and the clod fine sand in the mud of milling wheel bottom seriously wraps up milling wheel, leads to milling wheel knife
Piece operating temperature more and more higher, the clod that milling wheel periphery mills out and fine sand also more closely can adhere to caking because of high temperature, lead to milling
Wheel skidding cannot continue operation, so being frequently necessary to be promoted to ground through being manually rinsed, or even cuts.It is repeatedly lifted up milling wheel
Not only reducing effect increases artificial consumption, is also unfavorable for slurry trench stability and the control of groove milling perpendicularity, and a large amount of clear water rinses
Cause waste and environmental pollution.Therefore, develop milling wheel flusher in a kind of suitable ultra-deep soil layer and seem very necessary.
Content of the invention
The present invention is to provide for a kind of slotter milling wheel flusher, by being pressed into fresh slurry or clear water from mud tube
Spray by nozzle, directly rinse milling wheel or climb cutting wheel rotation direction is rinsed, drive periphery clod together from milling wheel bottom simultaneously
Siphon away through overfall mouth, milling wheel operating temperature can also be reduced while improving bottom land mud balance hang-up, can more effectively put
Change bottom land mud, prevent clod that milling wheel periphery mills out due to high temperature attachment caking pack tightly cannot operation and need to be promoted to ground
Rinse, working performance can be greatly enhanced, reduce due to the cell wall unstability wind being repeatedly lifted up causing of activity duration length and milling wheel
Danger.
For achieving the above object, the technical solution used in the present invention is as follows: a kind of slotter milling wheel flusher, including
Grouting Pipe, nozzle, mud tube and union joint, described nozzle is arranged on above milling wheel, good luck milling wheel rotation direction, and by note
Slurry pipe, union joint connect mud tube, for directly rinsing to slotter milling wheel in subterranean wall bottom land, reduce milling wheel and work long hours
Temperature, improves bottom land mud parameter.
Described Grouting Pipe is steel pipe or cast iron pipe, and described mud tube is to bear >=the high-pressure hose of 2mpa pressure.
Described nozzle is located at the distance on the cutter head of milling wheel > 5cm, nozzle and horizontal sextant angle are 30 ° ~ 90 °.
Between described Grouting Pipe, mud tube and milling bucket, mechanically segmentation is fixed.
All connected using bump joint or mantle fiber between described Grouting Pipe, mud tube and union joint and between nozzle and Grouting Pipe
Connect.
The invention has the beneficial effects as follows: present invention work efficiency compared with the technology in existing ultra-deep stratum or cement stratum
Height, can reduce the number of times that clod bag jail needing of leading to of milling wheel is promoted to ground artificial flushing, can be greatly enhanced working performance,
Reduce and cause cell wall unstability or the not good risk of degree control due to being repeatedly lifted up milling wheel, reduce milling wheel and work long hours temperature,
Improve bottom land mud parameter, labour can also be saved using this machinery simultaneously, reduce the labor intensity of workman.Test through engineering practice
Card, the present invention is easy to operate, stable.
Brief description
Fig. 1 is the milling wheel flusher front view of the present invention；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate this
Bright rather than limit the scope of the present invention.In addition, it is to be understood that after having read the content of present invention instruction, art technology
Personnel can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Fixed scope.
As Fig. 1, shown in 2, a kind of slotter milling wheel mud supplementary device, including Grouting Pipe 4, nozzle 6, mud tube 2 and company
Joint 3, nozzle 6 is arranged on above milling wheel 8, good luck milling wheel 8 rotation direction, and connects mud tube by Grouting Pipe 4, union joint 3
2, can directly carry out the flushing operation of slotter milling wheel at ground wall chase bottom, reduce milling wheel 8 and work long hours temperature, improve bottom land mud
Slurry parameter.Grouting Pipe 4 is steel pipe or cast iron pipe, and mud tube 2 can be high-pressure hose, needs to bear to be not less than 2mpa pressure；Slip casting
Pipe 4 diameter according to mud flow rate set, mud tube 2 should in Grouting Pipe 4 diameter identical or be slightly larger than slip casting pipe diameter.Nozzle 6 sets
Put above milling wheel, good luck milling wheel 8 rotation direction, need to be apart from cutter head 7, more than 5cm, nozzle 6 with horizontal sextant angle with 30 ° ~ 90 ° is
Preferably.
Grouting Pipe 4 and mud tube 2 are fixed using mechanical system segmentation with milling bucket 1.Certain due to being subjected in operation process
High pressure, therefore the union joint 3 of Grouting Pipe 4, mud tube 2 and nozzle 6 is all connected using bump joint or mantle fiber.
This flusher mud tube top should be connected with slush pump, and after fixing when slotter is constructed, decentralization carries out milling simultaneously
