Abstract

The invention discloses a shield tail brush abrasion real-time monitoring system, a shield tunneling machine and a manufacturing method. The real-time monitoring system comprises an optical fiber abrasion sensor, an optical fiber demodulator and a control end, wherein the optical fiber abrasion sensor is provided with a plurality of grating parts and abrasion parts in one-to-one correspondence with the grating parts, and when the abrasion parts are abraded to be damaged, the corresponding grating part is disconnected from other parts of the optical fiber, the optical fiber demodulator is connected with the optical fiber abrasion sensor, and the control end is electrically connected with the optical fiber demodulator. According to the shield tail brush abrasion real-time monitoring system, the shield tunneling machine and the manufacturing method, the sealing state of the shield tail brush can be monitored in real time, data are real-time, and judgment is accurate.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a real-time monitoring system for shield tail brush wear, a shield machine and a manufacturing method. Background technique [0002] As the cross-river and sea tunnel gradually presents the characteristics of "large diameter, high water pressure, and long distance", a great test has been put forward for the safety of shield machines in tunnel engineering. "High water pressure and long distance" all put forward higher requirements for the shield tail seal of the shield machine, and the wear and tear of the shield tail brush and whether it has resilience are factors that affect the performance of the shield tail seal. During construction, the wear and tear of the shield tail brush often occurs, which leads to the failure of the shield tail seal. In severe cases, major accidents such as casualties may occur. At present, there is no effective method for detecting the wear an...
