Abstract

Disclosed is pipe jacking equipment. During work, a motor I drives an upper half concave-circular tool post and a lower half concave-circular tool post to rotate forwards; a motor II drives an upper half convex-circular tool post and a lower half convex-circular tool post to rotate reversely; the upper half concave-circular tool post, the lower half concave-circular tool post, the upper half convex-circular tool post and the lower half convex-circular tool post cut the soil at the front end during rotation; the upper half concave-circular tool post and the lower half concave-circular tool post cut the left end into a concave-circular-arc head during rotation; the upper half convex-circular tool post and the lower half convex-circular tool post cut the right end into a convex-circular-arc head during rotation; and the cut soil and water injected by a water injection pump are stirred to form slurry, and the slurry is pumped by a slurry pump and then drained outside a jacking pipe. During the advancing process of the pipe jacking equipment, a hole with a concave-circular-arc section at the left end and a convex-circular-arc section at the right end is formed; and afterwards, a long-distance concave-convex type pipe jacking pipeline is formed in the advancing processes of pipelines with concave-convex type sections one by one.

Fig. 2 is the upward view of the present invention；

Fig. 3 is the A A view of Fig. 1；

Fig. 4 is the cross-sectional view of push pipe.

In figure: 1, housing, 2, steel plate support one, 3, steel plate support two, 4, upper half recessed dise knife post, 5, convex upper half tool post, 6, electricity Machine one, 7, motor two, 8, cutter head, 9, lower half recessed dise knife post, 10, lower tool post, 11, rotating shaft, 12, dividing plate, 13, muddy water Storehouse, 14, work chamber.

Detailed description of the invention

Accompanying drawing is a kind of specific embodiment of the present invention, and pipe jacking equipment is divided into the muddy water of front portion by this embodiment dividing plate 12 The work chamber 14 at storehouse 13 and rear portion, work chamber periphery is provided with housing 1；Dividing plate is fixed in the rear end of steel plate support one, steel plate support one The centre of motor 1 shell is fixed in front end, and the upper end rotating shaft 11 of motor one is fixed with upper half recessed dise knife post 4, motor one time End rotating shaft 11 is fixed with lower half recessed dise knife post 9；Dividing plate is fixed in the rear end of steel plate support two, and motor is fixed in the front end of steel plate support two The centre of 27 shells, the upper end rotating shaft 11 of motor two is fixed with convex upper half tool post 5, and the lower end rotating shaft of motor two is fixed with down Semi-convex dise knife post 10；Upper half recessed dise knife post and lower half recessed dise knife post one recessed dise knife post of composition, the side surface of recessed dise knife post is installed There is multiple cutter head 8；Convex upper half tool post and lower tool post one dome tool post of composition, the side surface of dome tool post is provided with Multiple cutter heads；The concave arc of recessed dise knife post cross section coincide with the dome arc of dome tool post cross section.

Described housing is left end with concave arc, right-hand member with the shell of dome arc.

Described recessed dise knife post and dome tool post are installed in muddy water storehouse.

When the present invention works, the injection location water under high pressure between recessed dise knife post and dome tool post, motor one are driven by water injecting pump Upper half recessed dise knife post and lower half recessed dise knife post rotate forward, and motor two drives convex upper half tool post and the reversion of lower tool post, upper half Recessed dise knife post, lower half recessed dise knife post and convex upper half tool post, lower tool post in rotation by the soil cutting of its front end； Left end is cut into concave arc head, convex upper half tool post, lower cutter in rotation by upper half recessed dise knife post, lower half recessed dise knife post Right-hand member is cut into dome arc head in rotation by post；The concave arc head of left part matches with the dome arc head of right part；The soil of cutting Body stirs into mud with the water body of water injecting pump injection, and mud is arranged outside push pipe after being aspirated by slush pump, and pipe jacking equipment is pushing away forward Entering middle formation left end with concave arc, right-hand member with the hole of dome arc section, thereafter, the pipeline of concave-convex type section saves one one The follow-up of joint is formed the concave-convex type push pipe pipeline of distance.
