It ensure that the security reliability of construction, and reach energy-saving and environment-friendly purpose.
The optional implementation of detection device 4 is described below.
Referring to Fig. 1 and Fig. 3, in some embodiments, detection device 4 includes laser and target 6.Laser be mounted on into
In the working pit of well head, for issuing laser.Target 6 is installed on first shell 1.Wherein, the laser of laser transmitting can be shown
On target, if laser deviates the center of circle of target, the jacking direction of cutting system 3 deviates from direction initialization.Target 6 is mounted on
In first shell 1.
The central axes of the light and design jacking that issue according to setting, laser coincide, i.e., kiss with the central axes of jacking pipeline
It closes.Due to the position of laser be it is fixed, be mounted in working pit, laser issue laser direction be determining.If
There is the case where laser is not located at the target center of circle, then illustrates that cutting system deviates from direction initialization.
Referring to Fig. 1 to Fig. 3, target 6 is vertically mounted at the top of the rear end of first shell 1, and target is outside.When work, preset
By laser, Vertical Launch laser, laser are beaten on the center of circle of target forward for the rear end of push pipe tunnel track.If push-bench is pushing up
Original track is deviated from when pipe, the position that laser beats in target can deviate from the target heart.By video camera in target 6 target
Point position is transmitted to outside tunnel on station display screen.At this time, it may be necessary to start correction drive device 5, to adjust cutting machine head
Traffic direction.First sensor 54, second sensor 55,3rd sensor 56 can detect each correction according to the transformation of resistance
The distance of stretch out and draw back of oil cylinder guarantees the safe operation of each correction oil cylinder.
After each correction oil cylinder movement, second shell 2 swings certain angle relative to first shell 1, to realize posture tune
It is whole.Since cutting system 3 is mounted in second shell 2,2 pose adjustment of second shell in place after, the posture of cutting system 3 with
In place.After 3 pose adjustment of cutting system is good, after cutting a period of time, the position of first shell 1 can be with second shell 2
Change in location shows pose adjustment in place to realize that laser hits the center of circle of target 6 again.
To observe whether jacking direction deviates direction initialization convenient for operator, detection device 4 further includes video camera and shows
Display screen.Video camera is for shooting target and laser.Display screen is connect with video camera, for show target that video camera takes and
The relative positional relationship of laser.
Above-mentioned target 6, video camera are such as mounted in the same cabinet, display screen be set to the ground outside working pit or
In person's equipment, in order to observe.
In order to realize that automatic deviation correction, push-bench further include controller, controller is used for the correction position control according to setting
The movement of correction drive device 5.When detecting that laser is deflected downwardly target, then controller controls corresponding oil cylinder to drive second
Shell 2, so that cutting system 3 is rotated up, until laser is located at the center of circle of target.It should be noted that above-mentioned adjusting
Process is real-time.

The T mouth of valve 92 passes through piping connection hydraulic oil container 16.
The rectification work process of push-bench is described below.
The course of work: when push-bench is constructed, push-bench rotates side in front and pushes ahead, meanwhile, by slush pump from into slurry
Pipe squeezes into the mud with certain pressure, and the frictional force reduced in jack-in process between tube wall and the soil body is covered using thixotropic slurry,
And the soil body of loss is filled, reduce soil deformation, sedimentation and water proof.When jacking works, do not fully entered in push-bench head
Before in soil, the reaction force as caused by knife cutting is greater than the frictional force between push-bench and guide rail, and push-bench may
The rotation opposite with cutterhead direction of rotation is generated, the generation of this phenomenon is not at this moment prevented with reduction move speed method often not
It can prove effective.Therefore, certain method must just have been taken into the initial stage in hole in push-bench to prevent from deflecting.In cutting jacking
In the process, if discovery laser point deviates from the center location of target it is necessary to rectify a deviation in time over the display, push-bench is allowed to locate always
The linearity of its jacking is kept under fine tuning state.
Confirm whether cutting system 3 promotes along desired trajectory direction, from the laser transmitter for promoting vertical hole set
The light beam of sending, the target 6 for 3 top of cutting system of going directly, through internal video camera in the touch screen display of station
