Conventionally, as shown in FIG. 5, as a waterproof plate for preventing rainwater from entering a basement floor such as an underground parking lot or a basement in a torrential rain, for example, a flat waterproof plate is taken out from a storage place, It is known that the waterproof plate is fitted into a guide recess from above and dropped into a guide member standing on a side wall to prevent water from entering (see Patent Document 1).
Japanese Patent Laid-Open No. 2004-162260

  However, in the conventional rainwater-infiltrated waterproof board, the person manages and installs the waterproof board at the discretion of the person, and it is difficult to respond quickly at night when there is no person. Even if there is a drainage groove at the entrance, it will be clogged with dust and dirt if maintenance is not done, and rainwater will immediately enter the basement. Furthermore, even in the case of heavy rain exceeding the drainage capacity of the drainage channel, rainwater may enter the basement floor. The rainwater-infiltrated waterproof board according to the present invention has been proposed to solve such problems.

The gist for solving the above-mentioned problems of the rainwater infiltration waterproof plate according to the present invention to achieve the object is as follows:
At the entrance with a waterproof plate,
Water sensors that detect water are respectively installed in both drainage grooves provided on the upper and lower sides of the slope connecting the entrance and the basement floor,
In the middle of the pipe connecting the drainage ditch on the upper side of the slope and the rainwater trough, a flow meter for measuring the amount of rainwater increase is provided,
The rainwater trough is provided with piping for draining to a miscellaneous drainage tank,
Both the water sensor and the flow meter are respectively connected to a control device, and the control device is connected to a drive device and an alarm device for raising and lowering the waterproof plate,
The controller is
The drive unit is driven by the water detection of both water sensors, and the waterproof plate is in a horizontal state.
Is set to stand upright from
When it is raining, both water sensors do not detect water and the flow meter measures the flow rate due to rain water, or the water sensor does not detect water in the upper drainage groove and the flow meter If only the water sensor in the lower drainage ditch does not detect the flow of water and continues to detect water, the centralized control center will be given a specific signal indicating either clogging in both of the drainage ditches. It is set to transmit automatically .

The waterproof plate includes a manual handle that can be manually erected .

  According to the rainwater infiltration waterproof board of the present invention, the control device automatically determines that rainwater has entered the underground floor by the water sensors of the drainage grooves provided at the upper and lower sides of the slope leading to the underground floor. Then stand up the waterproof board provided at the entrance. This prevents rainwater from entering automatically even without a resident manager, and in the case of heavy rain exceeding the drainage capacity, or the drainage clogged with dirt and other dust, allowing rainwater to enter. Even in some cases, it is automatically prevented. When a clogging alarm is issued to a central management center or the like, the building manager will have an opportunity to clean the drainage ditch, improving maintenance.

In addition, the flow meter of the drainage groove on the upper side of the hill is used to determine the momentum of rainfall, especially during heavy rains, so whether to raise a waterproof plate or to warn that the drainage channel may be clogged Judgment becomes easy.
Furthermore, the timing of raising the waterproof board also prevents the intrusion of rainwater by raising the waterproof board when both drainage grooves on the upper and lower sides of the slope are likely to overflow with rainwater. Will be able to.

  As shown in FIG. 1, a rainwater ingress waterproofing board 1 according to the present invention is provided at a basement entrance on the first floor in a structure 3 having an underground floor 2 such as an underground parking lot. In the vicinity of the waterproof plate 1, there is a drainage groove 4, and there is also a drainage groove 6 at the entrance of the first basement below the slope (slope) 5.

  Water sensors 7 and 8 are respectively installed in the drain grooves 4 and 6 provided at the upper and lower portions of the slope 5. The water sensors 7 and 8 are, for example, sensors that are switched on by a float that floats on water, or sensors that are switched on when electricity is conducted between terminals exposed to the outside by the water. is there.

  The water sensors 7 and 8 are connected to a control device 9 (see FIG. 4) (not shown), and the control device 9 is connected to a driving device 10 that raises and lowers the waterproof board 1 and an alarm device 11.

  As shown in FIG. 2, the drainage groove 4 on the upper side of the slope 5 has a flow meter 12 such as an electromagnetic flow meter and an impeller flow meter for measuring an increase in rainwater in addition to the water sensor 7. It is provided on the way. A rainwater tank 14 is provided at the end of the pipe 13 and is further drained to a miscellaneous water distribution tank by the pipe 15.

  As shown in FIGS. 2 to 3, the waterproof plate 1 is made of steel or aluminum, has a width of about 6 to 8 m, and a vertical length (height at the time of standing) of about 50 to 60 cm. When the waterproof board 1 is erected, a rubber bush 16 is provided on one of the abutting surfaces in order to abut against the receiving portions 3c provided on the walls 3a and 3b of the structure 3 and to keep the water stop.

  As shown in FIG. 4, the timing of raising the waterproof plate 1 is automatically instructed by the control device 9, but for example, in the vicinity of the lower position of the groove lids 4 a and 6 a in the drain grooves 4 and 6. The water sensors 7 and 8 are provided, and when the water sensors 7 and 8 detect the water, the control device 9 drives the drive device 10 which is a drive motor through the driver, so that the waterproof plate 1 is substantially removed from the horizontal state. I try to stand upright.

  In addition, when the water sensor 7 of the drainage groove 4 on the first floor above ground detects water and the flow meter 12 indicates the maximum flow rate, the control device 9 switches to the alarm device 11 as shown in FIG. An instruction is given and a warning that water may accumulate in the basement is issued by the speaker 17a or the lamp 17b. Thereafter, if the water is further increased and the water sensor 8 of the drainage groove 6 in the basement 2 detects water, the waterproof plate 1 may be erected in accordance with an instruction from the control device 9.

  The waterproof plate 1 is rotated by a manual handle so that the waterproof plate 1 can be erected in an emergency in the event of a power failure. It is erected by being driven and transmitted, for example, by being connected to.

  Further, when the water sensor 7 or 8 does not detect water during rain and the flow meter 12 measures the required flow rate due to rain water, the side structure 4b of the drainage groove 4 is clogged with dirt or the like. In this case, the control device 9 also transmits a specific determined signal related to clogging to the central control center or the like by wire or wireless. As a result, at least overflow of rainwater due to clogging of the drainage grooves 4 can be prevented, so that efficient maintenance can be performed.

  In the drainage groove 4 on the upper side of the slope 5, the water sensor 7 does not detect water, and the flow meter 12 does not detect the flow rate of water at all, and only the water sensor 8 in the drainage groove 6 on the lower side of the slope 5 has water. If this is continued for several hours, the drainage groove 6 may be clogged with dirt and the like. In this case as well, the control device 9 is wired or wirelessly connected to the central control center or the like. Then, a specific signal related to clogging is transmitted. Thereby, it is possible to prevent the underground floor 2 from overflowing with water.

After the waterproof board 1 is erected, when the water sensors 7 and 8 do not detect water and the flow rate becomes almost zero in the flow meter 12, the waterproof board 1 is instructed by the control device 9. Thus, the original horizontal position is restored.
Thus, clogging of the drain grooves 4 and 6 can be known by providing the water sensors 7 and 8 respectively in the drain grooves 4 and 6 on the upper and lower sides of the slope 5 leading to the basement 2. As a result, maintenance is facilitated, and in addition, underground flooding during heavy rain can be prevented.
