Embodiment
Technical solution of the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is described specific Embodiment is only explained the present invention, is not intended to limit the invention.
The horizontal correction method for planning track of a kind of TBM proposed by the present invention, tunneling boring hard rock mole include cutterhead, level Support cylinder and TBM navigation system.
As shown in Figure 1, the horizontal correction tracks of the TBM designed by the method for the present invention are by mutually circumscribed circular arc BC and circle Arc CD is formed, wherein, B points are the starting point of correction track, i.e., the horizontal distance deviateed in TBM cutter head centers with desired trajectory is E and cutterhead tunneling direction is with desired trajectory angleWhen TBM cutter head centers position, C points are that circular arc BC and circular arc C D is cut Point, D points are the terminal of correction track;Circular arc BC is in B points and TBM cutterhead front verticals, and circular arc C D is in D points and desired trajectory phase Cut.Comprise the following steps:

Step 2: determine min. turning radius R in TBM excavation operationsmin
When tuning is carried out in TBM excavation operations, in order to reduce Cutting Tool Damage, avoid tool apron or cutter hub from contacting palisades and make Into the condition for damaging and protecting scraper bowl lip to cross the limitation tuning such as quick-wearing, therefore, in TBM driving distances s, side knife moves Amount≤side knife movement limits value △ a, i.e.,
Abbreviation is:
Formula (1) is in formula (2):It is side knife amount of movement, R is TBM radiuss of turn, so that it is determined that TBM is most Tight turn radius Rmin, it is noted that the abrasion increase of lagging edge knife, side knife amount of movement limits value △ a also accordingly reduce.
Step 3: the horizontal distance e deviateed according to TBM cutter head centers and desired trajectory, cutterhead tunneling direction and pre- orbit determination The angle of markAnd TBM min. turning radius Rmin, the horizontal correction tracks of TBM are cooked up, realize that TBM tracks are rectified a deviation.
For TBM in linear advancement operation, a certain moment deviates desired trajectory (see position 1 in Fig. 1), at this time according to variation According to (the angle of horizontal distance e, cutterhead tunneling direction and desired trajectory that TBM cutterheads deviate with desired trajectory) and minimum turning Radius Rmin, R is selected according to actual conditions1、R2, horizontal correction track is cooked up, makes TBM on the correction track by continuous water Heibei provincial opera to, realize track rectify a deviation, as shown in Figure 1.
Formula (3) and formula (4), R1For the radius of circular arc BC in correction track, R2For the radius of circular arc C D in correction track, θ1 For the central angle of circular arc BC in correction track, θ2For correction track in circular arc C D central angle,
And meet

The driving distance of level correction is l
L=R1θ1+R2θ2 (6)
By taking TBM supports-promote-Huan Bu mechanisms experimental bench prototype structure parameter as an example, entangled according to TBM levels obtained above Inclined method for planning track, takes TBM straggling parameter e=3mm,Under Matlab environment, TBM is not for emulation With the correction track under deviation, as shown in Figure 2.As seen from the figure, 3 correction tracks are smooth curve, and trailing end of rectifying a deviation With estimating driving trajectory tangential.This method can quickly cook up required correction track according to different deviation datas.
The horizontal correction tracks of TBM cooked up according to step 3, by control the displacement of the horizontal support oil cylinder and then TBM tunings are controlled to complete horizontal correction.Control TBM tunings are carried out using phase cutting method, i.e., are controlled in tunneling process in TBM cutterheads Heart line and desired trajectory center line are tangent.
The general tunings of TBM are to use phase cutting method, i.e., TBM center lines and desired trajectory center line are tangent in tunneling process.Pick During when laser target target spot exceeds setting range, the correction track that step display three is cooked up is understood in TBM navigation system, By the TBM center lines in navigation system and the relative position of correction track, the displacement of controlled level support cylinder adjusts cutterhead Deflected in tunneling process, realize that TBM center lines and correction trace centerline are tangent in tuning driving, be eventually returned to original make a reservation for Track.When TBM laser targets target spot exceeds setting range again, repeat the above steps and rectify a deviation.
Although above in conjunction with attached drawing, invention has been described, and the invention is not limited in above-mentioned specific implementation Mode, above-mentioned embodiment is only schematical, rather than restricted, and those of ordinary skill in the art are at this Under the enlightenment of invention, without deviating from the spirit of the invention, many variations can also be made, these belong to the present invention's Within protection.
