One pipe section 21a is connected to a development chamber of the water pressure cylinder 11 via a control valve 24, and a second pipe section 21b is connected to a contraction chamber of the water pressure cylinder 11 via a ball valve 25. Therefore, when the waterproof door 4 is closed, the manual switching valve is switched from the neutral position I to the II position, or the electromagnetic on-off valve 23 is switched from the neutral position a to the open position b by remote control, whereby the first switching valve is switched. The water is supplied to the developing chamber of the water pressure cylinder 11 from the pipe portion 21a, and the water pressure cylinder 11 is developed at a constant speed by the control valve 24. At the time of opening, the manual switching valve is switched to the position III, and water is supplied from the second piping portion 21b to the contraction chamber of the water pressure cylinder 11. Further, a test pipe 27 is connected to the base end side of the ball valve 25 of the second pipe section 21b. The BOX portion shown in FIG. 3 is a piping portion inside the control box, and the OUT portion is a piping portion outside the control box.
[0018]
The watertightness test function according to the present invention forms the test water receiving tank 32 by the waterproof door 4, the support body 2, and the water stop wall 31 by forming the water stop wall 31 between the opposing surfaces of the auxiliary support part 2b. By injecting a predetermined amount of water into the test water tank 32, the waterproof door 4 is tested for water leakage. That is, on the opposing surfaces of the left and right auxiliary columns 2b, upper and lower fitting grooves 33 each having an open upper end and continuing to the side surface of the storage chamber 3 are formed, and a plurality of steps of drop dams 31a to 31d are formed in these fitting grooves 33. Are sequentially dropped from above, and both ends are fitted to each other to form a water blocking wall 31. As shown in FIGS. 6 and 7, a sealing member 34 that is compressed by water pressure is attached to the front side of the fitting groove 33. Here, the waterproof wall 31 has a waterproof structure by covering a waterproof sheet 35 covering the entire back surface. However, as shown in FIG. 8, the waterproof wall 31 is formed along the length direction on each joint surface of the drop dams 31a to 31e. The waterproof groove can also be formed by fitting the formed concave groove and convex ridge closely. Further, a drain valve 36 for draining water from the test water receiving tank 32 is provided in the lowermost drop weir 31a. Further, a drain pipe 38 is connected to the storage room 3.
[0019]
In the storage room 3, on the bottom side of the folded waterproof door 4, a weir storage part 37 for storing the drop weirs 31 a to 31 d and the waterproof sheet 35 is formed.
In the above configuration, when the entrance 1 is closed, the manual switching valve 22 (or the electromagnetic on-off valve 23) is operated from the neutral position I (a) to the position II (b) to supply the tap water to the tap cylinder 11. The water pressure cylinder 11 is advanced, the wire rope 12 is drawn in, and the waterproof door 4 in the storage chamber 3 is deployed and raised while standing up. Further, by pulling the waterproof door 4 in the upright state by the wire rope 12, the seal plate 8 of the waterproof door 4 is pressed against the seal surface 2 s of the support body 2 and the rear surface 3 a of the storage chamber 3, and the seal plate 8 is compressed. And stop the water. The manual switching valve 22 is returned to the neutral position I.
[0020]
Here, when performing the water tightness test, the drop dams 31 a to 31 d and the waterproof sheet 35 are taken out from the weir storage section 37 of the storage chamber 3, and the waterproof sheet 35 is set in the bottom of the storage chamber 3 and the fitting groove 33. The drop dams 31a to 31d are sequentially dropped into the fitting grooves 33 to form the water blocking wall 31 in which the entire back surfaces (the waterproof door 4 side) of the drop dams 31a to 31d are covered with the waterproof sheet 35. Next, by closing the ball valve 25 and setting the manual switching valve 22 to the III position, the valve 27a of the test pipe 27 is opened to supply water to the test water receiving tank 32 to store a predetermined amount of water. Thereby, it is tested whether or not there is water leakage from the seal plate 8 of the waterproof door 4.
[0021]
After completion of the water tightness test, the drain valve 36 is opened, and the water in the water receiving tank 32 is drained to the drain pipe 8 through the storage chamber 37. After draining, the drop dams 31 a to 31 d and the waterproof sheet 35 are pulled out from the fitting grooves 33 and stored in the weir storage section 37.
[0022]
Next, when the waterproof door 4 is to be opened, the ball valve 25 is opened, water is supplied to the contraction chamber of the water pressure cylinder 11 to contract, and the wire rope 12 is paid out. At this time, the lever operating dog 17 provided on the piston rod 11a pushes up and rotates the passive end of the L-shaped lever 15 so that the operating end protrudes forward. As a result, the lower portion of the upper door 4A is pushed forward, the upper door 4A and the lower door 4B are bent, and the opening / closing start mechanism 14 starts folding. Then, the wire rope 12 is fed out, and the upper door 4A and the lower door 4B are folded and stored in the storage room 3. In this open state, the front surface of the upper door 4A is also used as a cover for covering the storage room 3 and as a walkway.
[0023]
According to the above embodiment, in the closed position, the fitting groove 33 is provided on the opposing surface of the auxiliary support portion 3b on the water blocking surface side of the waterproof door 4, and the weir storage portion of the storage room 3 is provided after assembly or during maintenance. The water blocking walls 31 are formed by taking out the drop dams 31 a to 31 e housed in the 37 and sequentially fitting them into the fitting grooves 33, and the water receiving tank 32 is provided between the waterproof door 4, the support 2 and the water stopping wall 14. By forming, a water tightness test can be easily and quickly performed. Therefore, a high-precision water tightness test can be performed at the time of assembly and every maintenance, and it is possible to appropriately cope with a disaster caused by sudden abnormal weather.
[0024]
Further, since water can be supplied to the test water receiving tank 32 from the test pipe 27 taken out of the pipe outside the box of the water supply pipe apparatus, it is not necessary to arrange an extra water supply hose or the like, and the drain provided in the drop weir 31a is also provided. The water can be drained to the drain pipe 38 via the storage chamber 3 by the valve 37, and there is no need to prepare test instruments and tools.
[0025]
Further, since the weir storage part 37 for storing the drop weir 31a and the waterproof sheet 35 is formed in the storage chamber 3, the transport work is not required for the test, and the watertight test can be quickly performed.
[0026]
