In shield shell leading portion 4, be provided with console 5, can handle shield machine and shield driving etc. Casting telescoping tube 6 can stretch in the course of the work or turn back at shield machine, to adapt to native sand pump 3 and the variation that is located at casting pipeline 27 spacings on chassis 17. Lower tube coupling Shift cylinder 7 moves forward and backward use when tube coupling under lifting, and 12 of lower tube coupling hoist cylinders are under lifting, to allow when tube coupling it can oscilaltion.
Tube coupling of the present invention is tilting, no matter is that top shield structure oil cylinder or bottom shield structure oil cylinder all have dividing of left and right. As shown in Figure 4 be top shield structure oil cylinder A group 8, its left side (i.e. top in figure) one installs forwardly (near shield machine), and its right (in figure below) install lean on after. In addition, two other parameters of oil cylinder of this group are identical. In addition, when mounted, lower tube coupling fills a joint than upper tube coupling more, so the stroke of the stroke ratio bottom shield structure oil cylinder of top shield structure oil cylinder A group 8 and top shield structure oil cylinder B group 9 these two groups of top shield structure oil cylinders will be grown the width of a pipe joint joint, two groups of top shield structure oil cylinders must be with push action cylinders such as twin-stages.

See from rotary course: the rotational trajectory of 2 of tube coupling A, B be the great circle taking R as radius. When they rotate after θ, divide and be clipped to this 2 point of A ', B ', and in this course, their track does not exceed the inside of shield shell back segment 13 all the time. Equally, the rotational trajectory of 2 of C, D is the roundlet taking r as radius. As 2 of C, D around O point to turning clockwise after an angle θ, point be clipped to this 2 point of C ', D ', also do not exceed the inside of shield shell back segment-13, but every one side has all had more the so very little gap of δ than mounted lower tube coupling. This point is very crucial, it allow the rectangle tube coupling of very large section in the scope in a very little gap with regard to rotatable success. Thereby make the shield shell of rectangle tube coupling shield structure do more biggerly than tube coupling.
Rectangular Tunnel Construction is with in tilting two halves rectangle tube coupling shield-tunneling construction process, and many installations one all the time save lower tube couplings, as shown in Figure 9. Except can reducing the stroke of bottom shield structure oil cylinder, its waterstop sealing circle 20 is rubber rings of a sealing, and, on each face that needs sealing, be equipped with two seals circle, make like this stagnant water effect good.
