Abstract
Jacking pipeline sectional is detected the mud sleeve pressure size of each section, is turned on and off Solenoid ball valve valve by automatic constant pressure filling system proposed by the present invention automatically, and lubricated slurry, which is added to pipeline outer wall, backbreaks in gap, keeps the mud sleeve pressure on periphery balanced.It monitors mud sleeve pressure size in real time, realizes that automatic mend is starched.
Description
Technical field
The present invention relates to the push pipe fields that municipal pipeline is laid with, and in particular to the filling system during jacking construction.
Background technology
Currently, China's urban pipe network is built in progress just like a raging fire, traditional pipe network improving and construction be required for by
Road surface excavates again, not only causes economic waste, has an effect on traffic, pollution environment.Traditional construction method is compared, push bench process is applied
Tool has and need not excavate that ground, floor space is small, traffic impact is small, a rate of advance is fast, the advantages such as environmentally friendly, economic, efficient,
Through having obtained comprehensive promotion and application.
When jacking, by the injected hole reserved on tool pipe or concrete tube coupling, backbreaks to pipeline outer wall and be pressed into gap
A certain amount of lubricated slurry forms an annular mud sleeve in pipeline periphery, and support surrounding soil is stablized, and pipeline outer wall is reduced
Frictional resistance between soil layer, substantially reduces thrust force.The quality that mud sleeve is formed, is directly related to the effect of drag reduction, to
The success or failure of entire pipe-jacking project are influenced indirectly.
Common grouting method is that personnel enter inside pipeline, and slave head tube cheats slip casting successively to jacking, opens head pipe
Slip casting branch pipe valve, remaining slip casting branch pipe valve are in closed state, lubricated slurry are made to enter between head pipe outer wall and soil layer
Backbreak in gap, the slip casting time according to pipeline outer wall backbreak gap size calculate come；After slip casting for a period of time, next group is opened
Slip casting branch pipe valve simultaneously closes head pipe slip casting branch pipe valve；After slip casting for a period of time, cycle opens next group of valve and closing
The step of current valve, closes current valve, completes slip casting process until opening last group of valve close to jacking hole.This
The shortcomings of kind method has heavy workload, and the pressure at slip casting position is uneven, can not form the good mud sleeve of duration.
Invention content
The technical problem to be solved by the present invention is to：The deficiency for overcoming the prior art provides a kind of automatic constant pressure filling system,
So that pipeline outer wall is backbreak, pressure in gap is balanced, and mud sleeve continuity is good.
Automatic constant pressure filling system proposed by the present invention mainly by slurry storing tank, pulp-absorbing pipe, grouting pump, threeway, safety valve, return
Starch the compositions such as pipe, slip casting supervisor, slip casting branch pipe, Electric Appliance Cabinet, computer.Slip casting branch pipe includes pressure sensor, Solenoid ball valve, note
Starch hose, slip casting check valve.
Slip casting process is：Computer sends out signal Electric Appliance Cabinet and receives signal and open head tube valve, starts grouting pump, leads to
Pulp-absorbing pipe is crossed from, by lubricated slurry sucking slip casting supervisor, lubricated slurry is responsible for reach along slip casting and be noted at head pipe in slurry storing tank
Branch pipe is starched, by Solenoid ball valve, slip casting hose, slip casting check valve enters pipeline outer wall and backbreaks in gap；After reaching setting pressure,
Computer sends out signal, opens the next group of slip casting branch pipe Solenoid ball valve valve close to head pipe, and close head pipe electromagnetic ball
Valve valve, lubricated slurry are injected into corresponding pipeline outer wall and are backbreak in gap by next group of slip casting branch pipe；Reach setting pressure
Afterwards, computer sends out signal again, opens next group of slip casting branch pipe Solenoid ball valve valve, and closes current group Solenoid ball valve valve
Door, the above steps are repeated, last group of slip casting branch pipe Solenoid ball valve until closing on jacking hole is opened, and lubricated slurry is injected into pipe
Pipeline outer wall is backbreak in gap, and after reaching setting pressure, computer sends out signal-off current electromagnetic ball valve, and closes grouting pump,
A uniform mud sleeve is just formed in pipeline outer wall backbreaks gap at this time.

1. 6. return pipe of slurry storing tank 2. pulp-absorbing pipe, 3. grouting pump, 4. threeway, 5. safety valve, 7. slip casting supervisor, 8. electricity
12. Electric Appliance Cabinet of magnetic ball valve 9. pressure sensor, 10. slip casting hose, 11. slip casting check valve, 13. computer.
Specific implementation mode
Automatic constant pressure filling system proposed by the present invention is mainly by slurry storing tank（1）, pulp-absorbing pipe（2）, grouting pump（3）, threeway
（4）, safety valve（5）, return pipe（6）, slip casting supervisor（7）, Solenoid ball valve（8）, pressure sensor（9）, slip casting hose（10）, note
Slurry check valve（11）, Electric Appliance Cabinet（12）, computer（13）Composition.
Example one：Slip casting process for the first time, computer（13）Send out signal Electric Appliance Cabinet（12）It receives signal and opens head pipe
Valve starts grouting pump（3）, pass through pulp-absorbing pipe（2）From slurry storing tank（1）It is middle to be responsible for lubricated slurry sucking slip casting（7）In, lubrication
Mud is responsible for along slip casting（7）Slip casting branch pipe at head pipe is reached, by Solenoid ball valve（8）, slip casting hose（10）, slip casting it is unidirectional
Valve（11）In gap being backbreak into pipeline outer wall；After reaching setting pressure, computer（13）Signal is sent out, is opened close to head pipe
Next group of slip casting branch pipe Solenoid ball valve（8）Valve, and close head pipe Solenoid ball valve（8）Valve, lubricated slurry pass through next
Group slip casting branch pipe is flowed into corresponding pipeline outer wall and backbreaks in gap；After reaching setting pressure, computer（13）Letter is sent out again
Number, open next group of slip casting branch pipe Solenoid ball valve（8）Valve, and close current group Solenoid ball valve（8）Valve recycles the above step
Suddenly, last group of slip casting branch pipe Solenoid ball valve cheated until closing on jacking（8）It opens, lubricated slurry is injected into pipeline outer wall and backbreaks
In gap, after reaching setting pressure, computer（13）Send out signal-off current electromagnetic ball valve（8）Valve, and close grouting pump
（3）, a uniform mud sleeve is just formed in pipeline outer wall backbreaks gap at this time.
During slip casting, slip casting supervisor（7）When interior pressure is more than setting maximum pressure, safety valve（5）It opens, lubricated slurry
Pass through return pipe（6）Flow back into slurry storing tank（1）In.
Example two：When jacking construction, lubricated slurry part leaks into surrounding soil and underground water, partly fills up new formation
Gap of backbreaking；Due to the complexity of geological environment, cause lubricated slurry in the inhomogeneities of each part leakage, the mud of formation
It is unbalanced to cover pressure, cannot effectively play the role of drag reduction, needs constantly to mend slurry.Work as pressure sensor（9）Monitor some
When backbreaking that mud sleeve pressure reduction is to minimum pressure setting value in gap outside injected hole position, feedback signal is sent out automatically and reaches meter
Calculation machine（13）, computer（13）By analysis, signal enabling grouting pump is sent out, current group Solenoid ball valve is opened（8）Valve will moisten
Slip slurry adds to pipeline outer wall and backbreaks in gap, keeps the mud sleeve pressure on periphery balanced, constantly.
It should be noted that the above is the exemplary case of the present invention, it is clear that described example is only the present invention one
Certain embodiments, rather than whole examples, for those skilled in the art, in the premise without departing from principle of the present invention
Under, several improvement and amendment can be carried out with various different modes, these are improved and amendment should be regarded as protection scope of the present invention.
