[0031] Specifically, six spray devices 003 are provided, and the six spray devices 003 are arranged at intervals along the circumferential direction of the annular support 001. When the radial dimension of the annular support 001 is large, by increasing the number of spray devices 003, it can be ensured that the inner side wall of the pipe segment is evenly coated with waterproof and fireproof and decorative materials.

The spray machine 310 includes a liquid pump, the liquid inlet of the liquid pump is in fluid communication with the material storage device 002, and the liquid outlet of the liquid pump is in fluid communication with the spray gun 320. The spray machine 310 can drive the slurry from the material storage device 002 to the spray gun 320, and the slurry is sprayed onto the inner wall of the pipe segment through the spray gun 320.

[0035] like Figure 1 As shown, a plurality of spray guns 320 are evenly distributed along the circumference of the annular support 001 .

[0036] Specifically, a plurality of spray guns 320 are evenly distributed along the circumference of the annular support 001, and the slurry is evenly sprayed onto the inner wall of the pipe segment through the plurality of spray guns 320, thereby avoiding uneven slurry spraying.

[0037] Furthermore, the plurality of spraying devices 003 are connected to the material storage device 002 through the material delivery pipe 201 respectively; the material delivery pipe 201 extends along a spiral line from the material storage device 002 to the spraying device 003.

[0038] Specifically, the material delivery pipe 201 is connected between the sprayer 310 and the material storage device 002 , and the material delivery pipe 201 extending along the spiral line can adapt to the change of the distance between the sprayer 310 and the material storage device 002 by telescoping.

[0039] like Figure 1 As shown, the tunnel spraying device also includes a mounting bracket 004, which is connected to the circular bracket 001, and the mounting bracket 004 is used to be installed at the tail of the shield machine.

[0040] Specifically, the mounting bracket 004 is connected to the annular bracket 001, and the annular bracket 001 surrounds the mounting bracket 004. The material storage device 002 is mounted on the mounting bracket 004, and a plurality of spraying devices 003 are arranged around the material storage device 002 at intervals.

[0041] It should be noted that the mounting bracket 004 and the circular bracket 001 can be connected in a floating connection manner, the mounting bracket 004 is installed on the shield machine, and the mounting bracket 004 is located on the inner side of the circular bracket 001. A plurality of elastic devices are connected between the mounting bracket 004 and the circular bracket 001, and the plurality of elastic devices are arranged at intervals around the mounting bracket 004, and the circular bracket 001 is floated around the mounting bracket 004 through the plurality of elastic devices. In this embodiment, the feed pipe 201 adopts a spring pipe fitting, which integrates the functions of the feed pipe 201 and the elastic device, which can not only ensure that the slurry passes from the storage device 002 to the spraying device 003, but also ensure that the mounting bracket 004 is aligned with the circular bracket 001.

[0051] In the embodiment of the present invention, the shield equipment includes a speed sensor 008, which is installed on the shield machine and used to detect the travel speed of the shield machine.

[0052] Specifically, the speed sensor 008 detects the traveling speed of the shield machine, and the controller 007 adjusts the traveling speed of the shield machine according to the spraying thickness and the spraying uniformity. When the shield machine is excavating at a certain speed, the controller 007 adjusts the spraying machine 310 according to the spraying thickness and the spraying uniformity, thereby ensuring that the slurry on the inner wall of the pipe segment is evenly distributed by adjusting the spraying speed.

[0053] During operation, each sprayer 310 drives the slurry from the storage device 002 to the spray gun 320. Before spraying, the sprayer 310 drives the slurry to fill the feed pipe 201, and when the controller 007 controls the sprayer 310 to start, the slurry is sprayed from the spray gun 320 onto the inner wall of the pipe segment.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
