Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
Example 1
The atmospheric pressure working cabin device for the slurry shield comprises an air cushion cabin 2, wherein a person cabin 5 and a slurry cabin 6 are respectively arranged on the front side and the rear side of the air cushion cabin 2, a front cabin plate 4 and a rear cabin plate 3 are respectively arranged between the person cabin 5 and the air cushion cabin 2 and between the slurry cabin 6 and the air cushion cabin 2, a partition plate 1 is respectively arranged on the left side and the right side in the air cushion cabin 2, the air cushion cabin 2 is divided into two parts by the partition plate 1, and an atmospheric pressure space 7 is formed among the two partition plates 1, the front cabin plate and the rear cabin plate 3;
sealing doors 8 for connecting the ventilation cushion cabin 2 and the person cabin 5 are respectively arranged on the partition board 1 and the front cabin board.
The atmospheric space 7 may be communicated with the cabin 5 and the cushion cabin 2 by a sealing door 8. Normally, the sealing doors 8 on the partition boards 1 of the air cushion cabin 2 are all in a closed state, and when equipment such as an atmospheric camera and an atmospheric ultrasonic distance meter installed in the atmospheric space 7 is required to be maintained or replaced, the equipment can enter the atmospheric space 7 through the sealing doors 8 on the front cabin board 4 to be maintained or replaced.
