Definitions
- the first requirement is quick stiffening with it the purpose of pressure and shear-resistant bedding of the tubbing tube can be fulfilled.
- the liquid property of the mortar must quickly disappear and a shear strength is formed, because liquid mortar takes up the load of the segment weight and the load on the undercarriage of the trailer on which the mortar storage container among other installations and pumps are located, depriving the loads of deformation of the segment ring.
- the second requirement is good flowability around the To be able to completely fill the cavity.
- the third requirement is a longer processability of the mortar.
- the mortar is mixed and pumped into the storage container, in it by a Agitator kept moving and from there through hose lines and pressed pilasters into the annular space.
- the pilots act These are specially designed pipes that are flush all around in usually welded shield tail made of solid steel are.
- the pressing takes place continuously during the advance for the width of a segment ring (approx. 1 to 2 m). Also after a long break of up to approx. 1.5 hours, a must It may still be possible to pump the mortar without having to high pump pressure must be applied.
- the invention is therefore based on the object at the outset Design the pressing method so that the mortar over is pumpable for several hours and can therefore be processed, but still reached a minimum shear strength within a short time.
- the mortar hardens due to the thixotropic effect not, but only gets stiffened, and if after an interruption is pumped again, due to the lubricating effect of sand-lime stone flour, the entire contents of the pump lines and liquefy the pilaster again.
- the pressure peak when pumping back is reduced and thus difficulties that arise from thixotroping, buffered again.
- the high lubricity of the sand-lime brick makes it possible even, the mortar mixture as additional aggregates crushed sand and Add grit, which further increases the initial shear strength can be pumped, but pumping back after about an hour with controllable pressures.
- the additives to the mortar are preferably selected so that a shear strength of 5 to 10 KN / m 2 is achieved after about 30 minutes. This ensures that as the advance progresses, the mortar is sufficiently resilient when the ring has completely emerged from the shield tail and the buoyancy is fully effective.
- Fig. 1 shows that in the mountains 1 by shield driving approximately circular cavity 2 is driven into the tubbings 3 are installed, between the reveal of the cavity 2 and an annular space 4 remains in the tubbings, the diameter of which is larger than the outer diameter of the segment, that with mortar must be completed.
- Fig. 2 shows schematically how this is done. That the arranged in the shield jacking device Cutting head 5 progressively creates a cavity in the mountains, built into the segment rings 6 as the shield advance progresses become. The last segment ring 6a remains in the shield jacket 7 clamped so that he with the advancing shield at a distance from the boundary of the excavated annulus remains.
