Description
Technical field
The present invention relates to the slurry shield machine field of constructing tunnel, and in particular to a kind of slurry shield useless slurry exhaust system.
Background technology
At present, with a large amount of constructions of domestic outer tunnel, shield machine becomes first-selected, and slurry shield is with its excellent pressure control
Performance processed, is widely used in river, Tunnel Engineering that is excessively extra large and having higher requirements to sedimentation is crossed.In slurry shield construction
When, dregs is transferred out by mud channel by slush pump, and often tunneling a segment distance needs to extend mud channel, prolongs
Need to disconnect mud tube when stretching, the mud emission in mud tube is exactly a problem for needing to solve.
Conventional useless slurry tapping equipment be by the foul water tank below the mud emission in tunnel mud tube to stretch system,
Then slurries are discharged by sewage pump.The shortcoming of this device is that the speed that slurries are emitted from mud tube is slower,
Stand-by period is long, and operating personnel always do not discharge in slurries and begin to carry out changing pipe operation completely, and mud is just directly discharged
To in tunnel；In addition the foul water tank below mud stretch system is limited by space, causes its storage slurry volume not enough, adds sewage pump
Take out slurry speed and the plasma discharge speed of mud tube is difficult to accomplish to match completely, cause slurries to diffuse out from foul water tank or pump depletion.
It is difficult to accomplish slurries zero-emission using this conventional slurry-discharging equipment, the cleaning in tunnel is made a big impact, while can also makes
Into the waste of bentonite slurry, increase construction cost.
The content of the invention
The purpose of the present invention is for above-mentioned the deficiencies in the prior art, there is provided one kind can quick, leak free discharge mud
The slurry shield of the mud in pipe changes pipe slurry-discharging equipment and plasma discharge mode.
The technical scheme is that what is be achieved in that：A kind of slurry shield changes pipe slurry-discharging equipment, including with air cushion storehouse phase
Dredge pump even, dredge pump is connected with closed slurry can, and closed slurry can is provided with liquid level sensor, lower liquid level sensor and storage
Slurry tank pneumostome, the stock inlet of closed slurry can is divided into two-way, wherein being provided with the way after master control ball valve pass through again pulp-inlet pipe
Ball valve is connected with pulp-inlet pipe, is connected with discharge pipe by discharge pipe ball valve, separately leads up to membrane pump connection foul water tank, foul water tank
Connect pulp-inlet pipe ball valve, discharge pipe ball valve respectively after sewage ball valve；Pulp-inlet pipe two ends be disposed with pulp-inlet pipe control ball valve and
Pulp-inlet pipe gate valve, between pulp-inlet pipe control ball valve and pulp-inlet pipe gate valve pulp-inlet pipe pneumostome is disposed with, and discharge pipe two ends are disposed with
Discharge pipe controls ball valve and plasma discharge sluice valve, and between discharge pipe control ball valve and plasma discharge sluice valve discharge pipe pneumostome is provided with.
A kind of slurry shield changes pipe plasma discharge mode, carries out in the following manner：(1) liquid level in air cushion storehouse is dropped
It is low, close pulp-inlet pipe control ball valve, pulp-inlet pipe gate valve, discharge pipe ball valve and plasma discharge sluice valve, open it is closed go out slurry can and storage
Slurry tank pneumostome, the slurries in pulp-inlet pipe and discharge pipe can be entered internally in closed slurry can, when closed in the presence of pressure
When liquid level in slurry can sets liquid level higher than upper liquid level sensor, pulp-inlet pipe pneumostome and discharge pipe pneumostome are opened, while
Start dredge pump by the slurries dispatch in pipeline to air cushion storehouse；(2) as the slurries amount in pipeline is gradually reduced, when can not expire
During the conveying capacity of sufficient dredge pump, the liquid level in closed slurry can be reduced, when liquid level sets liquid level less than lower liquid level sensor,
Dredge pump and master control ball valve are closed, sewage ball valve is opened, remaining slurries are drained into and are placed in mud in pulp-inlet pipe and discharge pipe
In foul water tank below slurry pipe, then the slurries in foul water tank are delivered in closed slurry can by membrane pump, when closed storage slurry
When liquid level is higher than the setting liquid level of upper liquid level sensor in tank, start dredge pump, by a small amount of residue slurries dispatch in foul water tank extremely
In air cushion storehouse, carry out changing pipe operation after slurries in mud tube are racked up and finished.
The present invention directly extracts the mud in tunnel mud tube using sewage pump, and mud emission speed is fast；Simultaneously using close
The system closed, can accomplish basic No leakage, it is ensured that tunnel is cleaned, and reduces the usage amount of pulping agent, is conducive to environmental protection, while
Reduce construction cost.This apparatus structure is simple, easy to operate, practical, is environmental protection, the important leverage of standard construction.
