Problems solved by technology

[0003] At present, there are very few methods for dividing the excavation cycle of the open TBM construction data, mainly based on the penetration before and after the breakpoint of the excavation cycle breakpoint of the TBM construction data and the experience value as the entry point of the cycle division, dividing the initial excavation section and the smooth excavation section section, but the method of division of excavation cycle is relatively general, the division of excavation cycle is not precise and detailed, and has limited reference significance for engineering practice

Abstract

The invention relates to a method for dividing an open type TBM construction data tunneling cycle. The method comprises the following steps that A1, for each TBM tunneling cycle, parameter data of theTBM tunneling cycle are acquired after the TBM tunneling cycle; A2, based on the parameter data of the TBM tunneling cycle, division processing is performed on the TBM tunneling cycle, and a rising segment in the TBM tunneling cycle is determined; A3, the parameter data corresponding to the rising segment in the TBM tunneling cycle are acquired based on the rising segment in the TBM tunneling cycle and the parameter data of the TBM tunneling cycle; and A4, geological parameters in the TBM tunneling cycle are predicted by adopting a preset prediction algorithm according to the parameter data corresponding to the rising segment in the TBM tunneling cycle, and a prediction result is obtained. According to the method, the performance parameters of cutter disc torque equipment and two equipment control parameters such as the tunneling speed and the cutting disc rotating speed are utilized, the empty push segment, the rising segment, the stable segment and the stop segment of the open typeTBM tunneling cycle can be effectively divided, and the tunneling cycle division is more accurate and detailed.

Description

technical field [0001] The invention relates to the field of intelligent control of large tunnel excavation equipment, in particular to a method for dividing excavation cycle of open TBM construction data. Background technique [0002] Full-face hard rock tunnel boring machine (abbreviated as TBM) is a powerful tool for underground tunnel construction in my country. It has the advantages of fast tunneling speed, safe construction environment, high construction efficiency, and little disturbance to the surrounding environment. Among them, the division of open TBM excavation circulation section is helpful to improve construction efficiency, and has important engineering practical significance for TBM construction data analysis. [0003] At present, there are very few methods for dividing the excavation cycle of the open TBM construction data, mainly based on the penetration before and after the breakpoint of the excavation cycle breakpoint of the TBM construction data and the ...
