The muddy water circulation system comprises a slurry feeding pump 510, a slurry feeding pipeline 520, a slurry discharging pump 530 and a slurry discharging pipeline 540, wherein the slurry feeding pump 510 is connected with the slurry feeding pipeline 520, the slurry discharging pump 530 is connected with the slurry discharging pipeline 540, the slurry feeding pipeline 520 is communicated to the upper side of the soil bin 200, and the slurry discharging pipeline 540 is communicated to the lower side of the soil bin 200. The main drive 310 is connected to the cutterhead 100. The thrust cylinder 320 is disposed at the rear end of the shield body 300. The rear end of the screw 400 is provided as a slag hole 410, and the belt conveyor 600 is provided below the slag hole 410. The medium injection pipe 420 communicates with the screw 400.
In the implementation process of this embodiment, the propulsion cylinder 320 provides propulsion force for the tunneling machine in the tunneling direction, and the main drive 310 provides rotation torque for the cutterhead 100, so that the tunneling machine can continue to advance in the tunneling direction after cutting the rock stratum. The cutter head 100 is provided with a hob, the cutter head 100 rotates under the torque provided by the main drive 310, rock strata at the front end of the cutter head 100 are broken into rock blocks with different sizes to fall into the soil bin 200 along with the rotation of the cutter head 100 and matched with the propelling force provided by the propelling oil cylinder 320, the rock blocks are collected from the soil bin 200 to the upper part by the scraper 110 arranged on the cutter head 100 and then fall into the slag collecting hopper 330 to be collected by the slag collecting hopper 330, at the moment, the front end of the screw 400 is in butt joint with the slag collecting hopper 330, the rock blocks falling into the slag collecting hopper 330 are conveyed to the rear end of the screw 400 along the screw 400 and then fall onto the belt conveyor 600 through the slag outlet 410, the belt conveyor 600 conveys slag to a slag storage yard on the ground, and the medium injection pipe 420 is used for injecting slag modifier into the screw 400. In addition, the slurry pump 510 in the slurry circulation system delivers slurry to the soil bin 200 through the slurry delivery pipe 520, and slurry formed by mixing small-sized residue soil and slurry is pumped through the slurry discharge pump 530 and delivered to a matched slurry treatment system through the slurry discharge pipe 540.

The bottom of the slag collecting hopper 330 is provided with a liquid level sensor, and the liquid level sensor is used for controlling the liquid level of the muddy water injected into the soil bin 200 by the muddy water circulating system, so that the muddy water level injected into the soil bin 200 is ensured to be kept at the lower part of the slag collecting hopper 330 when the muddy water is operated in a TBM mode, and the muddy water is prevented from entering the slag collecting hopper 330. In TBM mode tunneling combined with a muddy water circulating system, the dregs carried out by the scraping plate 110 fall into the dreg collecting hopper 330 along with mud, so that liquid substances such as mud and the like do not enter the screw 400 and slip when the screw 400 is transported, and a water filtering tank is arranged on the front end plate 331 at the front end of the dreg collecting hopper 330 and used for filtering the dregs falling into the dreg collecting hopper 330, and the problem that the mud enters the screw 400 and is brought onto the belt 600 can be reduced.

In the case of performing TBM tunneling, the slurry circulation system of the tunnel boring machine is operated, and the slurry treated on the ground is pumped by the slurry pump 510 in the slurry circulation system and is fed into the soil bin 200 along with the slurry pipe 520. The muddy water in the soil bin 200 is mixed with the dregs cut by the cutterhead 100, the cutting surface of the rock stratum is soaked with the rotation of the cutterhead 100, the vibration generated with the tunneling work is weakened because of the muddy water in the soil bin 200, and dust generated in the tunneling process is adsorbed into the muddy water in the soil bin 200 to play a role in inhibiting dust emission.
It should be noted that, the slag in the soil bin 200 cannot be completely discharged by the slag collecting hopper 330, but only larger rock and partial slag can be cleaned, and the residual small-particle-size or dust-shaped slag can be left in the soil bin 200, but the residual slag and dust are mixed with the mud in the soil bin 200 through mud water, and the mud mixed with the slag is conveyed to the mud treatment equipment from the mud discharge pipeline 540 through the mud discharge pump 530 in the mud water system for filtering, and then conveyed to the soil bin 200 through the mud conveying pump 510 and the mud conveying pipeline 520 for circulation. The relatively large rock mass is conveyed to the slag collecting hopper 330 and discharged out of the soil bin 200 through the slag scraping plate 110, so that the problem that the rock mass blocks the slurry discharging pipeline 540 is avoided.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
