A Calculation Method for Segment Ring Number of Shield Machine

Abstract

The invention relates to the technical field of shield systems, in particular to a calculating method for pipe sheet ring numbers used for a shield machine. Through the assembly process of pipe sheetsof the shield machine and the prerequisite for assembly of pipe sheets, pipe sheet ring numbers for the shield machine are calculated. Concretely speaking, a push mode starting button and an assemblymode starting button on an operation panel of the shield machine and a stroke sensor on a push oil cylinder are connected with a control module such that the control module can access whether a pushmode is started, whether an assembly mode is started and stroke information of the push oil cylinder. According to the working process of the shield machine, a judgment is made as to whether an assembly machine finishes assembly of one pipe ring or not. Therefore, a control module records pipe sheet ring numbers such that information on the pipe sheet ring numbers is more reliable. Meantime, finally recorded errors of pipe sheet ring numbers caused by mal-operation of operation staff are avoided.

Description

technical field [0001] The invention relates to the technical field of shield tunneling systems, in particular to a method for calculating segment ring numbers of shield tunneling machines. Background technique [0002] In tunnel construction using shield machines, generally the ring number of the segment is used to measure the progress of the tunneling of the shield machine, and the ring number of the segment is used as a reference to count the construction information, equipment information and consumables consumption and other data. At present, the ring number of the segment of the shield machine is mainly calculated by using the stroke of the propulsion cylinder or the tunneling mileage of the shield machine measured by the guide system to calculate the ring number. However, in the actual shield construction, it is found that the ring number information obtained by the above method has an advanced or delayed deviation from the actual ring number, and due to the wrong op...

Problems solved by technology

However, in the actual shield construction, it is found that the ring number information obtained by the above method has an advanced or delayed deviation from the actual ring number, and due to the wrong operation of the shield machine operator or the measurement error of the guidance system, the It will lead to unreliable segment ring number information calculated by the above method, so that the wrong segment ring number needs to be corrected manually

However, in the case of errors in segment ring number calculation and failure to detect them in time, the shield machine will record various data that needs to be saved based on the wrong ring number information, which will affect the accuracy and queryability of the recorded data

Therefore, using the above-mentioned segment ring number calculation method, errors in the ring number calculation may be caused by the wrong operation of the staff or the measurement error of the guidance system, making the segment ring number information unreliable, and thus requiring frequent proofreading by the operator Segment ring number information

Using the above method not only reduces the accuracy of the data stored in the shield machine, but also greatly disperses the work energy of the operators
