Description

technical field [0001] The invention relates to the technical field of hob measurement, in particular to a device for accurately measuring the wear amount of a shield TBM hob and a matching measurement method. Background technique [0002] With the rapid development of my country's transportation engineering construction, shield TBM is widely used in the construction of subways, highways, railways, etc., and the stratum excavated by shield TBM is becoming more and more complex. The hob is to ensure the rapid excavation and Indispensable parts. According to the current tunnel excavation construction, the hob is extremely easy to wear and tear, and the wear of the cutter directly affects the construction efficiency and cost. Therefore, it is necessary to measure the wear amount of the hob cutter ring in time, so as to predict the wear rate of the hob, study the matching between different types of hobs and the formation, and provide a certain reference for hob design and shield...
