Beam section outlet top the second vertical tube section, first vertical tube section be equipped with pulp electromagnetic flowmeter, described second
Vertical tube section is equipped with overfall electromagnetic flowmeter, the pulp electromagnetic flowmeter and overfall electromagnetic flowmeter with the control
Unit connection.
Optionally, the screw pump and it is described enter beam section between pipeline on be additionally provided with first pressure sensor, it is described go out
Second pressure sensor, first pressure sensor and second pressure sensing are additionally provided on pipeline between beam section and the storage vat
Device is connect with described control unit.
Optionally, the pipeline at the storage vat overfall mouth is equipped with slurry traversing valve, on the pipeline of the slurry traversing valve entrance side
Branch is starched equipped with waste discharge, the waste discharge slurry branch road is equipped with waste pulp valve.

And it can be with real time measure.
3, the metering process of the utility model and mud jacking process carry out simultaneously, and metering process, which does not generate mud jacking process, appoints
The phenomenon that connection disturbs, and is not in cement grout solidification in metering process.
Detailed description of the invention
In order to clearly describe this patent, one or more attached drawing is provided below.
Fig. 1 is a kind of schematic illustration of the utility model embodiment.
Specific embodiment
Understanding for the ease of those skilled in the art to the art of this patent scheme, below to this in the form of concrete case
The technical solution of patent is described further.
As shown in Figure 1, a kind of circulation mud jacking grouting system, including circulation line, the circulation line are equipped with storage vat
And screw pump, the pipeline between screw pump grout outlet and storage vat overfall mouth include into beam section and out beam section；It further include that control is single
Member, it is described enter beam section entrance outside there is the first vertical tube section being located at below beam section entrance, it is described go out beam section outlet
Outer to have the second vertical tube section for being located at beam section outlet top, first vertical tube section is equipped with pulp Electromagnetic Flow
Meter, second vertical tube section are equipped with overfall electromagnetic flowmeter, the pulp electromagnetic flowmeter and overfall electromagnetic flowmeter
It is connect with described control unit.
In use, carrying out mud jacking according to normal work flow, slurries are hung down by the first vertical tube section and second
When straight tube section, electromagnetic flowmeter can obtain flow value in real time, and flow value is exported to control unit, and control unit is to overfall
The measured value of electromagnetic flowmeter and the measured value of pulp electromagnetic flowmeter take difference, then integrate to difference, can acquire slurries
Real-time intrusion.
Control unit can select the common PLC logic controller of industrial control field.
Optionally, the screw pump and it is described enter beam section between pipeline on be additionally provided with first pressure sensor, it is described go out
Second pressure sensor, first pressure sensor and second pressure sensing are additionally provided on pipeline between beam section and the storage vat
Device is connect with described control unit.
First pressure sensor is used to feed back the maximum pressure of current mud jacking pipeline, and second pressure sensor is worked as feeding back
The minimum pressure of preceding mud jacking pipeline.
For the PLC control unit in this, following procedure can be worked out:
(1) PLC obtains P1, P2, L1 and L2 in real time；
(2) according to P1, mud jacking revolution speed is controlled by frequency converter, P1 > Psetymax then reduces mud jacking revolution speed, P1
< Psetymax then improves mud jacking revolution speed；
(3) when P2 > Psetbmax is automatically into packing stage；Meanwhile pressure is all calculated during entire mud jacking and pressure maintaining in real time
Flow is starched, mud jacking flow is acquired by carrying out integral to (L1-L2)；
(4) during pressure maintaining, P2 > Psetbmax then reduces mud jacking revolution speed, and P2 < Psetbmax then improves mudjack and turns
Speed；
(5) after the dwell time arrives, pressure maintaining terminates.
Wherein:
P1 is first pressure sensor pressure value；
P2 is second pressure sensor pressure values；
L1 is pulp electromagnetic flowmeter flow value；
L2 is overfall electromagnetic flowmeter flow value；
Psetymax is preset maximum mud jacking pressure value；
Psetbmax is preset maximum dwell pressure value；
Psetbmin is preset minimum dwell pressure value.
Optionally, the pipeline at the storage vat overfall mouth is equipped with slurry traversing valve, on the pipeline of the slurry traversing valve entrance side
Branch is starched equipped with waste discharge, the waste discharge slurry branch road is equipped with waste pulp valve.
Waste pulp valve is for excluding waste pulp.
It optionally, further include high-speed stirred bucket, the high-speed stirred bucket is connected by supply lines with the storage vat.This
It is routine techniques, details are not described herein again.
It is easy to use in short, the utility model structure is simple, can the intracorporal grouting amount of real-time measurement beam, for normal
Slip casting process there is no any influence, and the magnitude measured is more accurate, is a kind of important improvement to the prior art.
