掃作業にも本装置の使用が可能である。[Explanation of Action] As shown in FIG. 2, the membrane 4 stretched on the inner surface of the concrete skeleton 2 with the cold insulating material 3 interposed therebetween has two parallel corrugations 7 in the central width.
The corrugation 7 is formed in the central part of the two parallel parallel corrugations 7 that are interrupted at right angles to the corrugation 7, that is, the corrugation 7 is formed in a cross shape in the central part of the plate surface, and the phase is changed by 90 °. The membrane 4 stretched in such a manner that it is alternately arranged in the vertical and horizontal directions and stretched.
The cleaning of the welding lines 8a and 8b will be described. Figure 3,
As shown in FIG. 4, the cleaning device A is connected to the winch wire 1
The limit switch 19 attached to the leading arm 15 is fitted between the two parallel corrugations 7 in the vertical posture formed on the membrane 4 while being suspended from 0. On the other hand, cleaning means B arranged at both ends of the arm 15
The respective air cylinders 20 are extended and pressed against the welding line 8a in the longitudinal direction of the membrane 4, and in this posture, the rotating brush 28 is rotated by the motor 25 to sweep up the powder in the welding line 8a to vacuum the dust. While continuing the work of suctioning from the nozzle 29 and collecting in the dust collecting box via the dust collecting and collecting hose 30, the cleaning device A slowly raises by the winch and cleans the welding line 8a portion by the upper and lower cleaning means B. At this time, the caterpillar 13 idles while contacting the surface of the membrane 4. When the limit switch 19 attached to the preceding arm 15 comes into contact with the first corrugation 7 in the horizontal posture of the upper membrane 4, as shown by the phantom line in FIG.
9 turns off. In response to this signal, the lifting of the cleaning device A by the winch is stopped, the drive of the rotating brush 28 of the cleaning means B is stopped, and at the same time, the cleaning is arranged vertically on the left end portion of both traverse rails 17 in the drawing. Means C
The air cylinder 20 extends to press the cleaning means C against the transverse welding line 8b of the membrane 4, and the motor 25 drives the rotary brush 28 to rotate.
The traverse rail 17 is operated by the action of the rack 17a and the pinion.
While moving to the right on the paper surface along the direction, the powder in the horizontal welding line 8b is swept up to remove the dust from the vacuum nozzle 29.
It is further sucked and collected in the dust collecting box through the dust collecting and collecting hose 30. When the cleaning means C reaches the right end of the transverse rail 17 on the paper surface, the cleaning means C reverses the rack 17a and the pinion, and the cleaning means C performs the finishing cleaning while performing the transverse cleaning.
At the left end of the paper surface, that is, at the time when the starting point is reached, the rotation brush 28 and the cleaning means C stop moving, and at the same time, the air cylinder 20 contracts and the pressing force of the cleaning means C on the membrane 4 is released. By this signal, the raising of the cleaning device A by the winch and the driving of the rotary brush 28 of the cleaning means B are restarted. Immediately after this restart, the limit switch 19 comes into contact with the upper corrugation 7 in the horizontal posture. However, the limit switch 19 is not operated by the timer circuit for the time period during which the upper corrugation 7 is passed. The winch does not stop even if it touches 7. While repeating the above operation, as shown in FIG. 8, after reaching the upper end of the side of the concrete skeleton 2 and cleaning the vertical and horizontal welding lines 8a, 8b for one cycle, the winch is moved for one cycle. After that, the wire 10 is unwound to lower the cleaning device A onto the bottom plate, and while cleaning device A is sequentially raised and stopped again, the work of cleaning the welding lines 8a and 8b of the cycle portion is performed on the concrete skeleton 2 side. This is done over the entire circumference of the section. Further, when cleaning the weld line portion of the membrane 4 stretched on the bottom, the cleaning device A is placed in a horizontal posture and the caterpillar 13 is driven, and the operation is the same as that described above. Is omitted. In addition to the cleaning of the welding line part, this device can be used for the bottom residual water treatment and cleaning work after the water filling test.
