Raw displacement.
To realize above-mentioned technical purpose, the technical proposal of the invention is realized in this way：
A kind of device for preventing from twisting during shield launching, including some brackets and reaction frame, pacify between the bracket
Equipped with track, shield machine is supported by the track, the bracket left and right ends, which are separately installed with, is supported by anti-rotational support, institute
State anti-rotational branch support and be equipped with support sliding surface, the bracket is respectively arranged on the left side and the right side the oblique arm of support shield machine, described
It is connected at left and right sides of track by the first supporting item with oblique arm.
Further, the anti-rotational support upper outside is connected by the second supporting item with the borehole wall.
Further, the anti-rotational support is connected with bottom between oblique arm.
Further, the reaction frame is connected by some supporters with the borehole wall.
Further, bottom passes through the built-in fitting phase with being embedded in concrete cushion respectively at left and right sides of the reaction frame
Connection.
Further, the top on the outside of the track is separately installed with block.
Further, the oblique arm of the left and right sides is in splayed structure, and the first supporting item of the left and right sides is in herringbone knot
Structure.
Further, first supporting item and the second supporting item are reinforced steel.
Beneficial effects of the present invention：
1st, shield machine is not only effectively avoided to twist in work progress is originated phenomenon, so as to ensure that posture in origination process
Stabilization and working security, but also can prevent due to attitude of shield machine change cause tunnel circuit there is the shape of deviation
Condition；
2nd, resistivity of the shield machine to moment of torsion is enhanced, shield machine safety of structure is ensured, so as to ensure shield machine
Safe and stable operation；
3rd, the stability of bracket is added, so that when reducing during shield launching cutterhead and being rotated clockwise with intersecting counterclockwise
Disturbance to surrounding soil, prevents the generation of the security incidents such as soil body landslide.
