At present, the construction of urban rail transit section tunnels is mainly a shield method, which is mainly divided into a slurry balance shield and an earth pressure balance shield, and the earth pressure balance method is mainly adopted in the construction of general subway tunnels due to stratum reasons. In the earth pressure balance shield construction, the soil discharge control is an important content in the earth pressure balance shield construction management, a shield machine cutter disc cuts a front soil body, muck is conveyed into a muck truck soil box by a belt conveyor through a screw conveyor, after each ring of tunneling is finished, the muck truck conveys the soil box to a working well, the soil box is lifted out by using a portal crane above a well mouth, and the muck is dumped to a designated place. The spiral conveyor is the unearthing equipment of the earth pressure shield, and in the construction of the earth pressure shield, the unearthing amount needs to be controlled by adjusting the rotating speed of the spiral conveyor, so that the unearthing amount and the shield excavation amount are kept balanced, and the shield excavation surface is in a stable state. In actual engineering, because the excavation soil layer is not a single soil layer, and the excavation depth is constantly changed, the soil output of the screw conveyor needs to be reasonably adjusted according to actual conditions. The excessive soil output can cause the stratum loss of the excavation surface to be excessive and collapse or cause the excessive settlement of the earth surface; when the soil output is too small, the pressure in the soil cabin can be rapidly increased, and the excavation surface is too large, so that the excavation surface is unstable or the surface of the earth is raised and damaged.
The method for judging shield overbreak and underbreak by manual work has the defects of poor real-time performance, low accuracy and the like, and can not meet the construction requirements of shield tunneling under complex geological conditions. Particularly, when the shield tunneling construction is carried out in a weak stratum, safety accidents such as ground settlement overrun, collapse, underground pipeline deformation damage, surface building structure inclination and the like are frequently caused due to the fact that the shield slag discharge exceeds the square.
The belt conveyor system is characterized in that a belt frame and a belt are additionally arranged at an earth outlet, the belt conveyor transports muck to a horizontal transportation section of the belt conveyor, the horizontal transportation section is always transported to a lifting well to a vertical transportation section, the vertical transportation section is lifted and transported to a muck pool, and a control system is required to be arranged in a shield machine operation room when the belt conveyor is in step with a shield machine belt conveyor. As long as carry the dregs through the belt weigher conveyer, the electron belt weigher just can accomplish weighing at transportation in-process, belongs to and send the limit to weigh, has accomplished continuous incessant measurement, and this has also improved work efficiency to a great extent, does not need artificial intervention, but the shortcoming of electron belt weigher is also very obvious, if the problem that the measuring accuracy is not high.
