Definitions
- a shield is provided for constructing tunnels with concrete walls, the shield containing hydraulic jacks which act on a pressing ring to press against the concrete, there being provided support devices between the rods of the jacks and the pressing ring, each support device having a rod with spherical end surfaces respectively in rolling contact with an associated jack rod and the pressing ring.
- the present invention relates to constructing tunnels and, more particularly, to shields which are used in the construction of tunnels with concrete walls.
- shields for constructing tunnels with concrete walls which press the concrete dressing material by the reactive force of shield jacks by means of a pressing ring mounted behind a carrier ring of the shield.
- the pressing ring becomes warped, which results in mutual displacement of the end portions of the rods of the shield jacks and the face surface of the pressing ring, as Well as in a transverse bending of the rods, the latter eflfect sharply decreasing the efficiency of the shield jacks and even putting them out of operation due to the appearanc of intolerable deformations.
- the present invention has for its principal object the provision of contact between the jack rods and pressing ring along a rolling surface.
- support devices are mounted between the rods of the shield jacks and the pressing ring, said support devices contacting the rods and the ring along rolling surfaces.
- a roller member of the support device is essentiallya rod having spherical end surfaces, enclosed in a casing rigidly secured in the pressing ring the end surfaces contacting fiat inserts, one of which is secured to the pressing ring, and the other-to the end portion of a shield jack rod.
- a spring-loaded ferrule For centering the rod of the roller support device inside the casing thereof and for returning the rod to its initial position after it is relieved of load, a spring-loaded ferrule is employed.
- FIG. 1 is an elevation view which diagrammatically shows, partially in section, a shield, built in accordance with the present invention
- FIG. 2 is a section view which shows a support device, according to the invention.
- FIG. 3 shows the support device with the pressing ring displaced relative the shield.
- the shield of the invention (FIG. 1) comprises a housing with a knife edge and carrier rings 2. Installed in the head portion of the shield housing are horizontal platforms 3 with devices 4 disposed thereon to perform mechanized working of the face.
- ring 5 which is used for pressing against the concrete dressing material and ring 5 will hereinafter be refered to as a pressing ring, for the sake of simplicity.
- hydraulic jacks 6 Disposed in the carrier ring 2 are hydraulic jacks 6 resting against the pressing ring 5 and serving for the pressing of the dressing material.
- the pressing ring is of annular form, and, depending upon the cross-section of the tunnel, may be of any shape.
- a roller member in the device 8 is essentially a rod 9 (FIGS. 2 and 3) having spherical end surfaces 10 and 11.
- the rod 9 is mounted in a casing 12 rigidly secured in the pressing ring 5.
- a springloaded ferrule is employed, said ferrule being rigidly connected to the rod 9.
- a shield for the" construction of tunnels with concrete walls comprising: a housing including a carrier ring; a pressing ring mounted within said housing behind said carrier ring for pressing against the concrete wall; jacks supported by said carrier ring and facing said pressing ring to apply force thereto; and support devices interposed between respective jacks and said pressing ring; each support device including means with spherical surfaces respectively in rolling contact with the associated jack and said pressing ring.
- a shield as claimed in claim 1 wherein said means comprises a rod having opposite ends which are provided with said spherical surfaces, each said support device including a casing rigidly secured in said pressing ring and a pair of flat inserts for each support device, one insert being secured to said pressing ring and the other to the associated jack, said spherical surfaces being in rolling contact with said flat surfaces.
- each support device comprises a spring-loaded ferrule installed inside the respective casing for centering said rod in said casing and returning the rod to its initial position after removal of force by the jack.
