Description
Technical field
The invention belongs to shield tunnel project fields, more particularly, to a kind of incrusted detection method of shield cutter.
Background technology
In recent years, with the fast development of social economy and urbanization process, it is great that shield tunnel technology has become China
Indispensable key technology in the infrastructure constructions such as traffic, the stratum involved by shield-tunneling construction also become increasingly complex.
When shield tunnel construction, with the rotation and propulsion of cutterhead, produced with the interaction of the soil body in cutterhead, cutter propulsion
Heat amount, heat pass to cutterhead in the form of heat transfer.Under normal circumstances, since the excavation face soil body is constantly transported, cutterhead
Cutter works normally, and in normal level, shield cutter maximum temperature only has 30 ~ 70 ° for shield thrust and torque.
But domestic a plurality of shield tunnel project example shows（Such as Yangzhou Slender West Lake tunnel, Guangzhou Metro Line 4, Chengdu
Subway Line 5, No. 8 lines of Wuhan subway, No. 4 lines of Line of Nanjing Subway, Nanchang subway Line 1）, shield is in batt, silty clay, mud
When being tunneled in the stratum such as rock, argillaceous siltstoue, argillaceous sandstone, the sticky particle in cutterhead digging face is rolled by cutterhead, is easily adhered to
On cutterhead surface.The clay of attachment is compressed under shield thrust, is consolidated, and hard mud cake is formed, then so that part
Tool failure（As hobboing cutter can not normal rotation and fail）, cutterhead opening is blocked, cutter head torque, thrust increase, cutterhead part temperature
Degree is rapid to be increased（Sometime up to 400 ° ~ 500 °）, the load of cutter head of shield machine and cutter is seriously increased, even more so that cutterhead material
Phenomena such as expecting attribute change.This aspect reduces cutterhead, cutting-tool's used life, the cleaning of another aspect mud cake is quite complicated,
Danger generates extreme influence for the normal implementation of shield engineering.
At present in Practical Project construction, cutterhead mud lining situation is mostly judged by thrust, torque and fltting speed, this
Often there is serious hysteresis quality in kind method, cutterhead mud lining is extremely serious when discovered, and it is even more impossible to accurately learn knife
Disk mud lining position, to bring bigger difficulty to follow-up mud cake cleaning work.
In scientific research field, has the proposition of less mud cake detection method at present, these methods are required to shield machine knife
Disk carries out related transformation and contact detection device is arranged：Or the dress of complicated mechanical detection mud cake is installed in shield soil storehouse
It sets, or needs that sensing device is installed in cutterhead digging face, then handled using complicated sensor-based system.This kind of mud cake is visited
Survey method has the following disadvantages：
1, contact detection device detects for single-point, and investigative range is limited, is unable to accurate judgement mud lining position and mud lining journey
Degree；Installation is complicated when a large amount of settings, and uneconomical；
2, contact detection device, especially when mechanical detection device there are certain hysteresis qualitys；
3, contact detection device squeezed by the soil body in cutterhead digging face or native storehouse, frictional influence, be easy destroyed, and system
Complexity, high failure rate.
Therefore, how to overcome the disadvantages mentioned above of current shield cutter mud cake detection, it is ensured that in real time, efficiently and accurately judge
Mud lining degree and position are very crucial in shield tunneling process.
Invention content
The object of the present invention is to provide a kind of shield cutter mud lining method of real-time based on infrared thermal imaging, is not necessarily to
Complicated sensing device is set in the storehouses Shang Huotu of knife cutting face, belongs to contactless monitoring method, have in real time, efficiently,
Failure rate is low, installs and use the advantages that simple, has in Shield-type machinery design and shield tunnel project construction field important
Application value.
To achieve the above object, technical scheme is as follows：A kind of shield cutter knot mud based on infrared thermal imaging
Cake method of real-time, it is characterised in that：Infrared thermal imaging device is set inside shield machine, and the infrared thermal imaging device is by red
Outer receiving part, transmission part and image-forming block composition, the infrared receiver component are used to receive the infrared ray of cutterhead transmitting, lead to
It crosses transmission part and sends image-forming block to, and by image-forming block real-time display cutterhead temperature.
Further, the infrared receiver component is located at cutterhead posterior center position, and image-forming block is located at shield driver and drives
Interior is sailed, infrared receiver component is connected with image-forming block by transmission part.
Further, the infrared receiver component, transmission part and image-forming block are integrated in one and are installed on inside shield.
Further, when the shield is tunneled in the earth formation, the knife cutting soil body, infrared receiver component receives cutterhead hair
The infrared ray penetrated, image-forming block real-time display cutterhead temperature；When cutterhead mud lining, part tool failure near mud cake, in shield
Temperature raising locally occurs under structure machine thrust, torque effect, image-forming block real-time display cutterhead temperature, engineer is fast so as to shield
Speed learns cutterhead mud lining situation, accurate judgement mud lining degree, precise positioning cutterhead mud lining position, to take accordingly
Technical measures.
The present invention has following advantages compared with prior art：
1, this monitoring method is contactless monitoring, and monitoring range is entire cutterhead face, can accurately judge cutterhead mud lining
Degree and position；Installation is simple, economical；
2, this monitoring method is contactless monitoring, and cutterhead temperature real-time display has synchronism, quickly, accurately；
3, this detection device is mounted on cutterhead rear portion, is not squeezed by the soil body in by digging face or native storehouse, frictional influence, it is not easy to quilt
Damage, and simple system, failure rate are low.
