AI Technical Summary

Problems solved by technology

Often in moderate to soft rock conditions, segment assembly takes longer, increasing the time requirement for each advance cycle
At the same time the machine works by locking the front and rear guards and operates as in a single guard when the clamps of the dual guard TBM are inoperable, so the duty cycle and the same timing issues apply for a single guard

Embodiment Construction

[0018] figure 1 and 2 A 3D view of a general propulsion housing 100 including a main hollow tank 170 and a propulsion ring 160 connected to a propulsion cylinder 150 of a TBM 310 is shown. Therefore, the movement (push / pull) of the propulsion housing 100 will be controlled by the propulsion cylinder 150 of the TBM 310 .

[0019] The ring of the propulsion housing may include stiffeners 180 on the propulsion ring 160 as structurally required. At the region of the propulsion ring 160, the thickness of the hollow tank 170 of the propulsion housing 100 may be structurally thicker. However, the extra thickness will be towards the inside of the pusher ring 160 .

[0020] The hollow tank 170 will be able to move back and forth within the gap between the rear guard 312 of the TBM 310 and the segmented rings 172 / 174. Therefore, the ID of the push can 170 should be greater than the OD of the segmented rings 172 / 174 , and the OD of the push can 170 should be smaller than the ID of ...

Abstract

A system and method for simultaneous excavation and segment erection of Tunnel Boring Machine (TBM) by Thrust shell system is an invention in tunnelling industry which will provide possibility of erection of the segmental ring while TBM is excavating and advancing forward with minimum interruption which will result in significantly increasing of the tunneling speed. The increased speed of the tunnelling will be reducing cost of the construction expressively. At this system and method, the TBM thrust cylinders will be pushing against previously installed segmental ring via combination of a thrust shell and an expandable ring while a new segmental ring is being built by TBM's segment erector within the Thrust shell's provided inner space.

Description

technical field [0001] The present invention generally relates to the utilization of a propulsion casing and an expandable ring for a shielded tunnel boring machine (TBM) intended primarily for use in tunnel construction and variations thereof. Background technique [0002] In typical / conventional soft ground tunneling with a protective machine, the forward movement is stopped for installing the section liner. This means that the advance cycle is the sum of excavation and segment installation, which often take equal amounts of time. In rock tunneling, the use of double shielded TBMs is on the rise due to the advantages they offer, primarily a single tunneling in which the final lining is installed. Since excavation and segment installation are simultaneous for dual guard TBMs, the advance cycle is determined by the longer of the excavation or segment assembly process. Often in moderate to soft rock conditions, segment assembly takes longer, increasing the time requirement ...
