Embodiment 2

[0038] Example 2, such as image 3 As shown, a shield machine that can measure the moisture content of slag, the slag feeding mechanism 1 includes a feed bin 102, the feed bin 102 is sealed with the pressurization bin body 210 of the pressurizing device 2, and the feed bin 102 communicates with the pressurized bin body 210 through the second gate 201, that is, the muck in the feeding bin enters the muck bin through the second gate. A first push plate 103 is arranged inside the feed bin 102, and the area of ​​the first push plate 103 is similar to the cross-sectional area of ​​the feed bin, and its area can be set as S2. The first push plate 103 is connected with the drive mechanism 101 that is arranged on the side wall of the feed bin 102, and the drive mechanism 101 promotes the first push plate 103 to move in the feed bin 102. When the muck bin needs to enter the slag, the second The gate is opened, the driving mechanism is stretched out, and the muck is pushed into the muc...

Abstract

The invention discloses a shield tunneling machine capable of measuring the water content of muck, and a water content measurement method. The shield tunneling machine comprises a main machine and a rear supporting part, the main machine comprises a cutterhead, a muck silo and a cutterhead drive which are sequentially arranged, and a water content measurement device is arranged in the muck silo and connected with a background control system; and the water content measurement device comprises a pressurizing device, a muck feeding mechanism and a water outlet mechanism are arranged on the side wall of the pressurizing device, the water outlet mechanism and the water outlet mechanism both communicate with the pressurizing device, and a data acquisition device is further arranged on the pressurizing device. The water content measurement device is mounted in the muck silo or a muddy water silo, muck is fed into the pressurizing device through the muck feeding mechanism, then the muck is extruded through the pressurizing device, thus water and the muck are separated, and then the water content of the muck is obtained through the simplest volume ratio.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a shield machine capable of measuring the water content of dregs and a method for measuring the water content. Background technique [0002] With the rise and development of the public transportation subway, the shield tunneling method has become the most important construction method for urban subways due to its advantages of safety, speed, strong adaptability to complex strata, and small surface settlement. Shield machines can be divided into mud-water balance shield machines and earth pressure balance shield machines. The earth pressure balance shield machine uses the muck in the soil bin as the medium to stabilize the excavation surface. The soil bin is formed between the cutter head and the rear partition of the cutter head. The cutter head rotates, and the excavated muck enters the soil bin, and then The muck is rotated out by the screw conveyor on the rear partiti...
