It mixes in muddy water storehouse 42 with the soil scaled off, then is transferred out soil by pipeline.
When installation:
First, it checks whether junction has loosened (mainly screw connection), need to be tightened as loosened；
Second, it connects with the mains, checks whether three-phase voltage is normal, and whether phase is correct, if abnormal and incorrect,
Try to keep it normal, otherwise forbids to be switched on；Third, also needs whether test electric leakage, electric protective device work just after power supply is normal
Often, further work can just be carried out.4th, try inspection and is placed on the horizontality of push-bench and foundation pit guide rail on guide rail 52
52 gradient is consistent.In general, push-bench had been made to correct to the instruction state of its dipmeter when leaving the factory.Its
Method is that all correction oil cylinders 31 are first retracted into bottom, is then placed on the top outside push pipe casing with frame level, if
State is spent in " 0 " that push-bench is adjusted to frame level instruction by method.Then, the adjusting spiral shell under the tilted instrument mounting rack of machine is adjusted
Silk, the numerical value for allowing dipmeter show are " 00.000 ", then fixed screw are tightened, and allow dipmeter fix tightly.Sometimes, this is adjusted
Process will be repeated could harmonize several times.
During long-distance transport, the fixed screw of dipmeter, it is possible to loosen, instruction is also just inaccurate.If
Dipmeter is tuned into horizontality, that just must once be adjusted using such as above-mentioned adjusting method.But at the construction field (site), in this way
Do often highly difficult, we can be used later approach, i.e., the gradient of push-bench and guide rail 52 is adjusted consistent.Specifically do
Method is the gradient that guide rail 52 is first accurately measured with level meter and straight steel ruler or level etc. towards jacking direction, then push pipe
Machine is placed on guide rail 52, unclamps the fixed screw of dipmeter later, and the angle that dipmeter indicates is transferred to and 52 gradient phase of guide rail
Unanimously.Finally the tilted instrument fixed screw of machine is tightened, fix tightly.
In a period of time of push-bench when just appearing or thereafter, soil is cut due to cutterhead and is formed by counter-force more than push pipe
Frictional force between machine and foundation pit guide rail 52 is big, so entire push-bench is possible to that opposite with cutterhead direction of rotation turn occurs
It is dynamic.Even if at this moment the fltting speed of push-bench is dropped to very low, it is intended to prevent such case to reduce the method for cutter disc torque
Generation, but rotation be often also inevitable.Therefore it has just appeared in a period of time in push-bench, we must use one
A little methods prevent its deflection, are such as coupled in push-bench side joint hinge or between the borehole wall with the chain block of a large-tonnage
Come, while push-bench promotes on one side, tightens chain on one side, can prevent push-bench from deflecting in this way.Or on push-bench shell
It burn-ons block, allows foundation pit guide rail 52 to block it and deflect, at this moment foundation pit guide rail 52 has to fix very firm.
Push-bench is typically due to than heavier, it, should be push-bench and preceding 3-5 in order not to allow it to plant down when encountering Soft Soil Layer
Section concrete pipe joins together, to prevent head relatively low.In addition, the effect that push-bench joins together with preceding 3-5 section concrete pipe is to prevent from pushing up
For pipe machine in progradation, the cutting moment of torque of cutterhead is excessive suddenly, and makes the generation of entire push-bench overturning accident.
With the propulsion of push-bench or pipe, various cables and pipeline can be also moved along, in order to prevent move in electricity
Cable etc. is broken, and fixed point of the cable in active well must be fixed on the borehole wall near hole, in this way with push-bench
It promotes, cable can increasingly relax, and without the more drawing the more tight, just not allow accident-proneness.
After push-bench fuselage fully enters hole sealing collar, it must just start slip casting, slurry set in this way is easy for being formed.
When use:
1, at hole, closure door is removed, and is confirmed without there are after any obstacle, and jacking can be just carried out.The initial top of jacking point
Into with two stages of normal jacking.Initial jacking refers to that push-bench connects to first segment pipe since jacking and connects with push-bench
Jack-in process before connecting.It is known as normal jacking after this.
It 2, should be depending on the steerings that are different and determining cutterhead of soil property before initial jacking.After cutterhead rotation, with main top oil cylinder
53, slowly by push-bench forward impelling, control threeway work ball valve and are in the water inlet of normal construction, spoil disposal state progress spoil disposal；When
When push-bench stops jacking work, control threeway work ball valve is in cleaning pipeline conditions and carries out cleaning pipeline.Push-bench is pushing up
Into in the course of work, it is necessary to control move speed and match with sludge volume, the relationship for only controlling them could be effective
Control the stabilization of excavation surface.
3, in the initial jacking stage, the service condition of observation push-bench is given much attention to, note abnormalities to find out in time
Analysis of causes processing.It cannot rectify a deviation in the initial jacking stage, can just rectify a deviation in normal jacking, but frequently to entangle, micro- entangle and see
Trend correction.
4, correction explanation: 31 position distribution of correction oil cylinder square tube after push-bench looks forward.
1) 2 are one group when correction oil cylinder 31 acts, and select 31 combination button of correction oil cylinder upwards, downwards, to the left, to the right
Any position presses the stretching of oil cylinder, contracting button.Such as selection 31 combination button of correction oil cylinder it is upward, press oil cylinder stretch by
Button, i.e. upper left, upper right oil cylinder are stretched together；The contracting button of oil cylinder is pressed, upper left, upper right oil cylinder are the same as contracting.Similarly, lower-left, bottom right or a left side
Same stretch, with contracting may be implemented in upper, lower-left and upper right, bottom right.
2) corresponding relationship of 31 stroke of correction oil cylinder and deviation adjustment angle see the table below:
Whether deviation correcting technology is grasped, and also can be considered the critically important foundation whether pipe-jacking technology is grasped.In correction process
In, if elevation and left and right at the same generate deviation, at this moment should first entangle height variation, after entangle left-right deviation.Because elevation is than left and right
Deviation difficulty is entangled.
In jack-in process, whether operator should give much attention to observe each current of electric and voltage in range of normal value
It is interior, once discovery is abnormal, it should shut down and be excluded.
This pipe jacking tunnelling machine is separately furnished with soil pressure formula cutterhead and screw conveyor machine, and the purpose is to be converted into mud water type push-bench
Soil pressure formula push-bench is constructed.Conversion method: the muddy water cutterhead and water inlet sludge drainage system of push-bench are removed, soil pressure is installed
