Embodiment 1

[0053] Embodiment 1, a kind of pipe jacking machine, such as figure 1 and figure 2 As shown, a shield body 6 is included, and a cutter head system driven by the host is arranged in the shield body 6 . The main engine includes a motor 5 or a hydraulic motor. The motor 5 or the hydraulic motor drives a main shaft 3 through a reducer 4. The front end of the main shaft 3 is connected with a conical cutter head 1. The conical cutter head 1 is provided with a hob 19 and a side scraper 2.

[0054] A stand 21 is provided on the outside of the shield body 6 , and a push-up system matched with the shield body 6 is provided on the top of the stand 21 . Under the rotating drive of the main engine and the vertical pushing action of the pushing system, the conical cutter head 1 rotates downward to excavate the soil.

[0055] The shield body 6 is detachably connected with a shield inner sleeve 15, the main engine is fixedly arranged in the shield inner sleeve 15, and the front end of the ...

Embodiment 2

[0060] Embodiment 2, a pipe jacking machine, the shield body 6 is connected with the upper end of the sleeve 15 in the shield body through the connecting baffle plate 14 by bolts. The connecting baffle 14 can transmit the thrust from the vertical support shoe 22 to the main engine; at the same time, after the downward construction is completed, the connecting baffle 14 is removed, and the shield body 6 and the sleeve 15 in the shield body are separated, and the pipe jacking machine can be realized. Recycling of the host.

[0061] The other structures of this embodiment are the same as those of the first embodiment.

Embodiment 3

[0062] Embodiment 3, a pipe jacking machine, a recovery oil cylinder 13 is provided between the shield body 6 and the sleeve 15 in the shield body. The recovery oil cylinder 13 can conveniently realize the separation of the shield body 6 and the sleeve 15 in the shield body.

[0063] Further, one end of the recovery oil cylinder 13 is hinged with the inner wall of the shield body 6 , and the other end is hinged with the upper end of the sleeve 15 in the shield body.

[0064] Other structures of this embodiment are the same as those of Embodiment 1 or 2.

Abstract

The invention discloses a recyclable construction method for a pipe jacking machine and its main engine, which solves the technical problems that the existing pipe jacking machine cannot perform shield construction on an integrated submerged pump house in a communication channel and the main engine is difficult to recover. The invention includes a shield body, a cutter head system driven by a main machine is arranged in the shield body, a sleeve inside the shield body is detachably connected to the shield body, the main machine is arranged in the inner sleeve of the shield body, and the outer edge of the cutter head system is arranged There is an outer edge cutter, the outer edge cutter is fixedly connected with the cutter head system in the circumferential direction, and the axial downward one-way rotation is hinged. system. The invention has wide application range, strong safety and high construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of integrated submerged pump house construction equipment, in particular to a recyclable construction method for a pipe jacking machine and its main engine. Background technique [0002] With the rapid development of cities, the space above ground becomes more and more limited, and the development of underground space is an inevitable trend of future urban development. Tunnel engineering has developed into an important project in the process of underground space development. Build communication channels and pump rooms between the tunnels. At present, the pump room in the communication channel includes built-in pump room and integrated submerged pump room. Since the built-in pump room has shallow depth, is easy to collect sand, and needs to be equipped with high-performance pumps, the integrated submerged pump room has Broad application prospects. [0003] At present, for the construction of the communicati...
