Abstract

The invention discloses a super-large diameter slurry balance shield tunneling machine. The super-large diameter slurry balance shield tunneling machine solves the problems of low tunneling efficiency, low tool replacement efficiency, serious potential safety hazard and the like of a slurry balance shield tunneling machine in the prior art. The super-large diameter slurry balance shield tunnelingmachine comprises a tunneling mechanism, a rear supporting electrical and hydraulic integration system, a fluid integration system, a slurry pipeline extension device and a dragging platform which aresequentially connected; the tunneling mechanism comprises a normal-pressure cutter head, a shield protection mechanism, a main drive system and a propulsion system, wherein the normal-pressure cutterhead is located at the front end of the shield protection mechanism, the main drive system is located inside the shield protection mechanism and is connected with the normal-pressure cutter head, theshield protection mechanism is provided with a central cabin, a pipe segment mounting machine and a mud circulation system, and the central cabin is located behind the main drive system; and the segment mounting machine is connected with the shield protection mechanism, and a slurry discharge port of the slurry circulation system is formed in the lower part of the shield protection mechanism. Thesuper-large diameter slurry balance shield tunneling machine can realize the one-time forming of a super-large diameter tunnel project, effectively improve the construction efficiency and greatly reduce the construction cost.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to an ultra-large-diameter mud-water balance shield machine. Background technique [0002] In the current tunnel construction, shield tunneling technology has gradually been widely used due to its advantages of high degree of automation, high construction safety, fast construction progress, low pollution, and low cost. Among them, the shield machine is a highly mechanized and automated tunneling lining complete set of equipment that adopts the shield method and integrates mechanical, electronic, hydraulic, laser and control technologies. Shields are generally divided into mud-water balance shields, earth pressure balance shields, and air pressure balance shields. [0003] Due to its unique advantages of high working pressure and precise pressure control on the tunnel face, the mud-water balance shield is widely used in tunnel projects such as crossing rivers, crossing seas,...
