Description
Technical field
The present invention relates to the dregs transportation system in a kind of shield machine, more particularly to one kind shield in shield compound stratum
A kind of dregs transportation system in machine.
Background technology
In subway shield tunnel construction, compound stratum is frequently encountered, compound stratum is to be dispersed with different times, different lithology
Or different rate of decay, show the stratum of DIFFERENT SOIL property.The infiltration coefficient of the physical property of ground and soil in the stratum
Differ greatly.In shield tunneling process, complicated geology is changeable, cuts hard rock during cutterhead, when and to cut water content different
Weak soil, the dregs after cutting enters behind storehouse of burying, and is sent to by the screw machine soil outlet on shield machine on belt conveyor, belt
Machine is made up of crane span structure slope section and chassis flat slope section, and belt feeder crane span structure slope section is arranged on immediately below screw machine soil outlet, in skin
With pipe sheet assembling working face is provided with the shield machine on the outside of machine slope section, existing shield machine crane span structure slope section inclination angle was designed
Greatly, the carrying roller spacing of its end is excessive, causes the dregs from screw machine soil outlet whereabouts excessive to belt impulsive force, causes dregs
On the pipe sheet assembling working face leaked on the outside of belt, the normal consolidation service in section of jurisdiction has been directly influenced.When shield machine face
When running into the high stratum of rich water amount, can be mixed in dregs has substantial amounts of water, and these water fall on belt feeder under screw machine soil outlet
Slope section end, water can drop onto shield tail consolidation service face along end, cause the serious ponding of the pipe sheet assembling scope of operation.Skin
The dregs transported with machine slope section sends belt feeder flat slope section to, and existing flat slope section is not provided with pushing off the slag facility, transported in belt
During dregs, the dregs leaked is entered below belt, is often occurred belt catching phenomenon, is caused dregs stoppage in transit accident.It is whole
Crane span structure slope section and the flat slope section of individual belt feeder are that the strap end of dregs is transmitted using enclosed annular belt by dregs
Send to after slag-soil truck, then pass back to the dregs of the head end progress of belt feeder next time below belt feeder and transport, when transport
When dregs viscosity is high, it can be attached on belt and pass back to belt top, during passback, the clay on belt can be got rid of
In shield locomotive frame, the pollution of construction environment in shield machine is caused.
The content of the invention
The invention provides a kind of compound stratum shield machine dregs transportation system, the shield in compound stratum shield is solved
The technical problem that the easy ponding in Ji Nei consolidation services area and operating environment are easily polluted by dregs.
The present invention is to solve above technical problem by the following technical programs：
A kind of compound stratum shield machine dregs transportation system, including shield machine Tu Cang, spiral transferring is connected with shield machine Tu Cang
Machine is sent, belt feeder crane span structure slope section head end is provided with below the soil outlet of conveying worm, in belt feeder crane span structure slope section
End is provided with belt machine trolley flat slope section, the end of belt machine trolley flat slope section is provided with vehicle frame afterbody soil outlet, in spiral shell
Consolidation service area is provided with below the soil outlet for revolving conveyer, belt feeder crane span structure slope section head end is provided with dash arc,
Pushing off the slag rubber closing cylinder, the head of the feed belt on belt feeder crane span structure slope section are connected with the soil outlet of conveying worm
End belt is arranged with yielding rubber roller group, and the feed belt both sides in belt machine trolley flat slope section are provided with mud guard,
The high-pressure spraying water system sprayed to tail pulley is provided with vehicle frame afterbody soil outlet.
Steel cleaning shoe is provided with vehicle frame afterbody soil outlet；The soil outlet of conveying worm is circular port.
The present invention is existing when solving the screw machine conveying slag charge in the propulsion of water rich strata shield machine to gush, and causes to spell
The problem of dress easy ponding in operation area and dregs easily drop, it is ensured that the cleaning in consolidation service area and the safety of consolidation service are entered
OK.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of compound stratum shield machine dregs transportation system, including the native storehouse 1 of shield machine, spiral is connected with the native storehouse 1 of shield machine
Conveyer 2, is provided with the head end of belt feeder crane span structure slope section 4 below the soil outlet 3 of conveying worm 2, oblique in belt feeder crane span structure
The end of slope section 4 is provided with belt machine trolley flat slope section 9, and the end of belt machine trolley flat slope section 9, which is provided with vehicle frame afterbody, to be gone out
Native mouth 11, is provided with consolidation service area 5 below the soil outlet of conveying worm 2, is set in the head end of belt feeder crane span structure slope section 4
There is dash arc 6, pushing off the slag rubber closing cylinder 14 is connected with the soil outlet 3 of conveying worm 2, on belt feeder crane span structure slope
The head end belt of feed belt 8 in section 4 is arranged with yielding rubber roller group 7, the transmission in belt machine trolley flat slope section 9
Belt both sides are provided with mud guard 12, and the high-pressure spraying water system sprayed to tail pulley is provided with vehicle frame afterbody soil outlet 11
System 10.
Steel cleaning shoe 13 is provided with vehicle frame afterbody soil outlet 11；The soil outlet 3 of conveying worm 2 is circular port.
First, geological characteristics are judged by early stage geologic prospect report analysis, select the soil outlet 3 of shield machine screw machine,
If the big stratum of rich water amount is from circular soil outlet 3, if from square soil outlet 3 during ground combination stratum；In shield machine
Crane span structure section front end increase the cucurbit jack of two 2, the belt gradient to adjust belt feeder crane span structure slope section 4 reduces slag
Soil drops to impulsive force when on belt conveyer after being come out from the soil outlet 3 of screw machine, and puts increasing to belt conveyer motor seat
Plus two long screw spirals are used for tightening belt, control belt deviation amount.Meanwhile, the transmission on belt feeder crane span structure slope section 4
Yielding rubber roller group 7 is set under the head end belt of belt 8, to increase the impact of buffering slag charge；Due to belt machine trolley flat slope
The length of section 9 is about 70 meters, in the course of conveying of slag charge, due to being shaken belt, rocks dregs and drops, in belt
Feed belt both sides in machine trolley flat slope section 9 are provided with mud guard 12, become semi-enclosed transport slag charge form, effectively solve
Soil drops problem；Belt feeder fortune is attached to a certain amount of clay on belt after turning around, it is impossible to fall in dregs case, steel
Matter cleaning shoe 13 serves the effect for sweeping slag, meanwhile, increase high-pressure spraying water system 10 is rinsed to strap end, is improved
The transfer efficiency of belt.
