Visual monitoring and management method of unearthed excavation in shield tunneling construction and visual monitoring and management system of excavated volume

Abstract

The invention provides a shield construction excavation visual monitoring management method and an excavation amount visual monitoring management system. The system comprises a shield PLC, a belt weigher, a wireless communication module and terminal equipment. The belt weigher is arranged on a shield tunneling machine belt conveyor and can collect shield construction parameters, and the excavationspeed, the pushing speed or the pushing stroke, the instant excavation amount and the current ring excavation amount are at least obtained through operation. The method comprises two parts includingexcavation speed monitoring management and excavation amount monitoring management. By means of the shield construction excavation visual monitoring management method and the excavation amount visualmonitoring management system, the excavation amount changing situation can be accurately and truly reflected in the shield tunneling process, analysis, evaluation and control on the excavation processand the final excavation amount are achieved, and process and result monitoring is conducted on shield construction. A system processing and display interface is visible, functions are complete, therequirements of different work conditions and different construction personnel can be met, and monitoring of a shield cab, field construction personnel and related management personnel is facilitated.

Description

technical field [0001] The invention relates to the technical field of shield tunneling construction, in particular to a method for visual monitoring and management of unearthed excavation in shield tunneling construction and a visual monitoring and management system for unearthed quantity. Background technique [0002] Earth pressure balance shield is the main equipment of shield tunneling method. The control of excavation volume is an important content in the construction management of earth pressure balance shield tunneling. In the construction of earth pressure balance shield, it is necessary to control the excavation volume by adjusting the speed of the screw conveyor. , so that the unearthed volume and the excavation volume of the shield machine are balanced, so that the excavation surface of the shield machine is in a stable state. Excessive unearthed volume will lead to excessive stratum loss of the excavation surface and cause excessive subsidence of the surface; to...

Problems solved by technology

However, there are deficiencies in this system: ①It is only conventional measurement and display, without considering many influencing factors of the excavated amount in the actual construction process, and without considering the relationship between the theoretical excavated amount, the measured excavated amount and the actual excavated amount; ②It is not based on the actual real-time adjustment and correction of shield construction parameters; ③The system interface has limited functions and cannot display shield-related construction parameters in real time, and cannot meet the needs of different working conditions and different construction personnel; ④The excavation volume data processing and display functions are not perfect , the unearthed status and existing problems cannot be directly reflected through the data; ⑤ The unearthed data can only be displayed in the shield cab, which is inconvenient for on-site construction personnel and relevant management personnel to view
