[0030] Please refer to the attached Figure 1-Figure 5 , shows a ventilation device for water diversion inclined shaft TBM construction provided by an embodiment of the present application, including: a wind tube cabin 1, a foldable wind tube 2 and a limiting member 8.

[0031] The wind cylinder cabin 1 is fixedly installed on the TBM trolley in an inclined state, with the first end of the wind cylinder cabin 1 facing obliquely downward, and the first end of the wind cylinder cabin 1 also facing the rear of the TBM excavation. A limiting member 8 is fixedly installed on the first end of the wind cylinder cabin 1. The foldable wind cylinder 2 includes a flexible cylinder 202, and a plurality of annular members 201 are fixedly connected to the outer side of the flexible cylinder 202. The annular members 201 are used to ensure that the flexible cylinder 202 is in an expanded state and to prevent the flexible cylinder 202 from rubbing against the ground. The annular member 201 located at the end of the flexible cylinder 202 is fixedly installed with the second end of the wind cylinder cabin 1.

[0032] The limiting member 8 has a limiting block 803 located at the inner side of the wind cylinder cabin 1 . The limiting block 803 is an elastic metal plate. The limiting block 803 is used to elastically limit the annular member 201 from sliding out of the wind cylinder cabin 1 .

[0033] like Figure 1 As shown in the figure, the bottom of the wind tube cabin 1 is fixedly connected with a first supporting leg 4 and a second supporting leg 5. Due to the design of unequal lengths of the first supporting leg 4 and the second supporting leg 5, the wind tube cabin 1 is in an inclined state.

[0034] The bottom ends of the first supporting leg 4 and the second supporting leg 5 are fixedly connected with a mounting plate 6, and the upper surface of the mounting plate 6 is provided with a mounting hole 7, so that the mounting plate 6 can be fixedly connected to the TBM trolley by bolts. The first supporting leg 4, the second supporting leg 5 and the TBM trolley can also be fixedly connected by welding.

[0035] In one embodiment, a protective net cover 3 is fixedly installed on the second end of the wind tube cabin 1 , and the protective net cover 3 plays a protective role to prevent debris from entering the foldable wind tube 2 .

[0036] In one embodiment, the protective net cover 3 includes: an annular flange 302, the inner edge of the annular flange 302 is fixedly connected to the grid 301, the inner side of the second end of the wind tube cabin 1 is fixedly connected to the mounting ring 1a, and the mounting ring 1a, the annular flange 302, and the annular member 201 located at the end of the flexible tube 202 are fixedly connected by bolts.

[0037] In one embodiment, a plurality of side holes 1b are opened on the side of the wind cylinder cabin 1, which can save the manufacturing materials of the wind cylinder cabin 1. At the same time, the side holes 1b are convenient for observing the amount of the foldable wind cylinder 2 inside the wind cylinder cabin 1; when the foldable wind cylinder 2 is folded and sent into the wind cylinder cabin 1, it is also convenient to perform auxiliary operations at the side holes 1b.

[0038] In one embodiment, the limiting member 8 includes: an insert block 801, a frame 802, and a limiting block 803. The insert block 801 and the limiting block 803 are fixedly connected at both ends of the frame 802. A socket 1d is provided on the outer side of the first end of the wind duct cabin 1. The insert block 801 is installed in the socket 1d, and the limiting block 803 is located inside the wind duct cabin 1. The insert block 801, the frame 802, and the limiting block 803 are an integrated structure and can be formed by bending a plate to ensure that the whole has a certain elasticity.

[0039] Generally, a plurality of limiting members 8 are provided, and the plurality of limiting members 8 are distributed in a ring array.

[0040] When in use, the wind cylinder cabin 1 is fixedly installed on the TBM trolley in an inclined state, and one end of the foldable wind cylinder 2 extends out of the wind cylinder cabin 1 and is connected to the ventilation equipment (such as a fan) installed in the tunnel. The ventilation equipment works to send air to the TBM construction site through the foldable wind cylinder 2. During the TBM excavation process, the wind cylinder cabin 1 moves forward with the TBM trolley, and the foldable wind cylinder 2 is continuously stretched to meet the needs of continuous ventilation.

[0041] Restriction 8 Figure 5 As shown in the figure, the limiting block 803 is located on the inner side of the wind cylinder cabin 1, which can limit the annular member 201 from sliding out of the wind cylinder cabin 1, but when the foldable wind cylinder 2 is pulled, the annular member 201 squeezes the limiting block 803, and the limiting block 803 and the frame 802 are deformed, so that the annular member 201 passes over the limiting block 803.
