Abstract
The utility model discloses a scouring apparatus for the cutterhead central area of a large-scale slush type shield machine, comprising a slush circulation system pipeline, a connecting pipeline, a booster pump, a flowmeter, a pressure gauge, a valve body, a cutterhead panel and a jet orifice. All elements are connected in sequence; the low-pressure slurry in the slush circulation system of the slush shield machine is supercharged; the supercharged slurry with a high pressure continuously scours soil through a nozzle at an inclined direction, and thereby soil is prevented from attaching to the cutterhead center; and the cutter and cutterhead are further protected.
Description
Technical field
The utility model relates to a kind of flushing device, particularly relates to a kind of large-scale muddy water formula cutter head of shield machine central area flushing device.
Background technology
Muddy water formula shield machine is that to keep the stable shield machine of excavation face, general diameter surpasses 10 meters the large-scale muddy water formula shield machine that is called through the soil pressure and the water pressure of mud hydraulic pressure balance excavation face in the muddy water cabin.Cutterhead is the carrier that the shield machine front end is used for the cutter of the smear metal soil body, is the main building block of shield machine.Cross in the Channel Engineering construction of river at certain, adopt the large-scale muddy water formula of 14.93m shield machine, because this engineering tunnel complicated geological condition, the long distance in tunnel is passed through the sand pebble layer and the compound stratum of high quartz content, and possibly have not clear obstruction; Deep foundation ditch stratum of living in all is saturated aqueous weak soil, fine sand layer, so cutterhead intensity, the cutter abrasion resistance is this engineering key of success.Under the relation of considering cutterhead intensity and geological conditions, the regional tool arrangement of large-scale slurry shield machine knife disk center is intensive, and the central area aperture opening ratio is minimum; Linear velocity when this zone cutter rotates is very little, very easily causes soil to adhere to obstruction, increases the cutter burden; Make cutter and cutterhead aggravation wearing and tearing, do not take any measure in former design, so very easily cause cutter life to shorten rapidly; Increased construction risk, will cause shield machine to tunnel when serious, made the engineering failure.
The utility model content
The utility model technical problem to be solved provides a kind of large-scale muddy water formula cutter head of shield machine central area flushing device; It makes high pressure muddy water through the oblique earth that washes away continuously of spout; Make it can not be, and then reach the effect of protection cutter and cutterhead attached to the cutterhead center.
The utility model solves above-mentioned technical problem through following technical proposals: large-scale muddy water formula cutter head of shield machine central area flushing device; It comprises muddy water circulatory system pipeline, connecting line, booster pump, flow meter, pressure gauge, valve body, cutterhead panel, jet; The muddy water circulatory system pipeline is connected with booster pump through connecting line, and booster pump, pressure gauge and flow meter are connected, and flow meter is connected with valve body; Valve body is connected with jet, and jet is fixed on the cutterhead panel.
The positive progressive effect of the utility model is: the utility model makes the mud of high velocity jet can fully break up central area soil; Make it incorporate mud in the very first time; And through muddy water circulatory system discharge muddy water cabin; Reach and prevent that the central area cutterhead from stopping up, improve central area knife cutting efficient, reach the purpose of protection cutterhead central area cutter.
Description of drawings
Fig. 1 is the principle schematic of the large-scale muddy water formula of the utility model cutter head of shield machine central area flushing device.
The specific embodiment
Provide the utility model preferred embodiments below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As shown in Figure 1, large-scale muddy water formula cutter head of shield machine central area flushing device, it comprises muddy water circulatory system pipeline 1, connecting line 2, booster pump 3, flow meter 4, pressure gauge 5, valve body 6, central area cutterhead panel 7, jet 8; Its order of connection is: muddy water circulatory system pipeline 1 is connected with booster pump 3 through connecting line 2; Booster pump 3, pressure gauge 5 are connected with flow meter 4, and flow meter 4 is connected with valve body 6, and valve body 6 is connected with jet 8; Jet 8 is fixed on the cutterhead panel 7; Flow meter 4 is used to measure the muddy water flow, and pressure gauge 5 is used to measure mud hydraulic pressure, and booster pump 3 is used for the muddy water supercharging.The utility model through booster pump, is transported to jet behind valve body, flow meter, the pressure gauge etc. with the muddy water that has certain pressure in the muddy water circulatory system pipeline.
The utility model makes the mud of high velocity jet can fully break up central area soil, makes it incorporate mud in the very first time, and discharges the muddy water cabin through muddy water circulatory system, reaches the purpose of protection cutterhead central area cutter, and then increases cutter life.
The foregoing description is as to the qualification of the utility model, all any modifications of in the scope of the utility model, being done, is equal to replacement, improvement etc., all belongs to the protection domain of the utility model.
