Description
Technical field
The present invention relates to shield machine maintenance technical field more particularly to it is a kind of clear up shield machine shield tail gas-tight silo device and
Method.
Background technique
When building tunnel with shield method, there can be certain gap with surrounding rock body at shield drive end unit section of jurisdiction, at this moment
Packing material is generallyd use to fill gap to guarantee integral strength, reduces ground settlement, or pass through slip casting at shield tail
Mode reinforce the rock mass of surrounding, be provided with injected hole on the section of jurisdiction that shield drive end unit is laid with, can in the injected hole of section of jurisdiction into
Row grouting operation.Packing material, grouting serous fluid and underground water flow into inside shield machine in order to prevent, in shield drive end unit and section of jurisdiction
Between shield tail brush is set, and the grease seal that is formed between shield tail brush is intracavitary places special grease, this space is shield machine
Tail sealing storehouse, it can effectively seal against the gap between shield shell and concrete pipe sheet, to prevent soil, water and grouting slurry
Liquid enters shield machine.Although playing certain sealing effect, has and be partially filled with material, grouting slurries penetrate into oil
Inside rouge seal chamber, the sealing performance of grease is influenced.Therefore it during shield machine is stopped using, needs to shield tail grease seal chamber
It is cleared up, the packing material of infiltration is cleaned out with slurries, the normal use of shield tail brush after guarantee.But due to shield tail
Even position is also inconvenient to dismantle when shield machine is inoperative, also it is not easily accomplished so directly dismantling to be cleared up.
Summary of the invention
The object of the present invention is to provide a kind of device and methods for clearing up shield machine shield tail gas-tight silo, can not remove shield
From the gas-tight silo between internal cleaning shield machine shield ventral brush under the premise of machine.
To achieve the goals above, the invention provides the following technical scheme:
A kind of device for clearing up shield machine shield tail gas-tight silo, which includes refrigerating plant, connecting tube and heat-exchanger rig, described to change
Thermal is connect by connecting tube with refrigerating plant, and heat-exchanger rig is arranged between two layers adjacent of shield tail brush.It will by freezing
Grease and infiltration injecting paste material therein between shield tail brush are freezed, and solid state is convenient to clean, since grease has lost
Fluid ability can directly remove section of jurisdiction and be cleared up.
Preferably, the heat-exchanger rig includes heat exchanging chamber, and the heat exchanging chamber is connect with connecting tube, and outlet is arranged.Heat exchange
Own temperature is changed by the medium with temperature in device.
It preferably, further include heating device, the refrigerating plant is connect by switching valve with connecting tube with heating device.Add
Thermal can be used for the grease of melting chilling, it is made to have higher mobility.
Preferably, further included air blower, the air blower are connect with switching valve.Air blower is used to freeze and/or add
Temperature buffer is carried out before heat, prevents in connecting tube and heat-exchanger rig short time quenching or shock heating damages or shorten the service life.
Preferably, different heat-conducting mediums are respectively set from heating device in refrigerating plant.Liquid nitrogen can be passed through in refrigerating plant
It is freezed, heating device can be heated by conduction oil or water.
A method of cleaning shield machine shield tail gas-tight silo, comprising the following steps:
A. stop the operation of shield machine；
B. open refrigerating plant, by between shield tail brush (2) grease and injecting paste material be refrigerated to solid-state；
C. stop refrigerating plant；
E. section of jurisdiction (7) below shield tail brush (2) are removed；
F. remaining injecting paste material between shield tail brush (2) is cleared up.
Grease is set to lose flowability with injecting paste material by freezing, convenient for clearing up it.
Preferably, increase step d after the step c before step e: opening heating device and add between shield tail brush
Heat, while extracting in the injected hole of section of jurisdiction the grease of flowing.Grease fusing point itself and it is more thermally conductive than injecting paste material, through being subcooled
Quick-thawing heats again after jelly, and grease is provided with higher mobility, and injecting paste material does not thaw sufficiently also, also in solid-like
State can clear up injecting paste material after extracting grease at this time.
Preferably, the temperature of connecting tube (3) and heat-exchanger rig is increased using air blower before opening the heating device.
Air blower avoids shock heating immediately after the quenching, extension connecting tube and heat exchange for tentatively heating up to connecting tube with heat-exchanger rig
The service life of device.
The invention has the following advantages:
1, the mobility that grease and injecting paste material are reduced by way of freezing is cleared up by way of removing section of jurisdiction, behaviour
Make simple and more efficient；
2, the grease and solid injecting paste material of flowing are cleared up after can also heating respectively；
3, air blower can play the role of temperature buffer, extend the service life of connecting tube and heat-exchanger rig；
4, heat-exchanger rig can also be heated or cooled seal grease according to environment temperature within the time without cleaning,
If winter conditions temperature is lower, grease viscosity is excessive, is not easy to be pumped between shield tail brush, by improving grease after heating devices heat
Mobility or summer environment temperature are higher, and grease mobility is excessive, and sealing effect is bad, drop after being cooled down by refrigerating plant
Low-flow improves viscosity, and so that the sealing effect is better.
