Problems solved by technology

As long as the muck is conveyed by the belt scale conveyor, the electronic belt scale can complete the weighing during the conveying process, which belongs to weighing while conveying, and achieves continuous and uninterrupted measurement, which also greatly improves work efficiency. , does not require manual intervention, but the shortcomings of the electronic belt scale are also obvious, such as the problem of low measurement accuracy

Abstract

The invention discloses a method and system for measuring the soil discharge amount of a shield tunneling machine and a medium. The method comprises the following steps of receiving real-time measurement data which at least comprise the belt speed of a belt conveyor for transmitting muck, the density of the muck, the section area, the temperature of the current muck and the excavation stroke; calculating a dumping deviation value according to the measurement data; and performing overbreak and underbreak monitoring alarm based on the soil discharge deviation value. The system comprises a belt tachymeter, a soil discharge amount scanner, a thermodetector, a soil discharge odometer, a control box used for controlling the belt tachymeter, the soil discharge amount scanner, the thermodetector and the soil discharge odometer to work, and an industrial personal computer. The method and the system at least have the following beneficial effect that the construction quality and efficiency can beimproved.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a soil displacement measuring system and method of a shield machine. Background technique [0002] Rail transit has entered a stage of rapid development in recent years, and the construction of urban rail transit has been fully rolled out in major cities. At present, the construction of urban rail transit tunnels is mainly based on the shield method, and the shield method is mainly divided into mud-water balance shield and earth pressure balance shield. Due to the stratum, the general subway tunnel construction mainly adopts the earth pressure balance method. In the construction of earth pressure balance shield, the control of excavation volume is an important content in the construction management of earth pressure balance shield. In the soil box, after the excavation of each ring is completed, the soil box is transported to the working well by the muck truck, and the gantry ...
