An embodiment of a remote monitoring system in an air dome control system according to the present invention will be described with reference to FIGS.
FIG. 1 is an overall explanatory view of the vicinity of a structure such as an apparatus for a remote monitoring system used for construction of a dome roof in the air dome construction method according to the present invention and a storage tank for equipment.
FIG. 2 shows a roof level measuring means for measuring the roof height position in the construction process of the dome roof from the outside of the structure such as a storage tank in the remote monitoring system used for the dome roof construction in the air dome construction method according to the present invention, and during the dome roof construction. It is explanatory drawing which shows the outline of the camera imaging | photography means which monitors the external shape of this roof.
1 is a storage tank, 2 is a dome roof, 3 is a bottom plate, 4 is a side wall, and 5 is a flexible membrane.
In the storage tank 1, air is constantly supplied to the lower part of the storage tank by an air dome blower 6 through an existing supply pipe 7. The supply pipe 7 is provided with an electromagnetic valve 8 for turning on / off supply. In order to keep the pressure in the storage tank 1 within a preset range, air is exhausted from the upper part of the storage tank 1 to the outside by using the exhaust pipe 9 of the existing piping in the storage tank 1. The exhaust pipe 9 is provided with an electromagnetic valve 10 for turning on and off the exhaust. The on / off operation of the solenoid valves 8 and 10 is performed by the remote monitoring panel 11.

  The inside of the storage tank in which the upper part of the storage tank 1 is covered with the flexible film body 5 in a sealed state is maintained at a predetermined pressure by adjusting the supply and exhaust air. This pressure maintenance is called primary pressure increase. The flexible membrane body 5 functions as a working scaffold in this primary pressure increase state, and an operator installs anchor pins and round steel on the flexible membrane body 5 (not shown). Further, an adhesive (not shown) is applied on the flexible film body 5 and a lath net / welding wire net (not shown) is arranged. After the arrangement of the net, the pressure in the storage tank 1 is increased to perform secondary pressure increase. By this secondary pressure increase, the flexible film body 5 is given a strength sufficient to withstand the weight of a mortar (not shown) or the like placed on the flexible film body 1. After the secondary pressurization, mortar is placed on the flexible membrane body 5, then watering is cured, roof reinforcing bars (not shown) are assembled, roof concrete (not shown) is placed, and the curing period is increased. In this case, the strength of the dome roof is confirmed. When sufficient strength is obtained, the air in the storage tank 1 is released, and a series of dome roof construction work is completed. Thus, in the work of dome roof construction, the pressure in the storage tank 1 is roughly divided into primary boosting and secondary boosting, and the primary and secondary boosting are for maintaining the dome shape in a well-balanced manner before and after that. In order to give the strength enough to withstand the weight change of the mortar or the like placed and placed on the flexible film body 5, it is necessary to change the pressure in the storage tank 1 as appropriate.

It is an internal pressure detection means provided with the internal pressure display detection board 14b. The internal pressure signal obtained by the internal pressure display detection panel 14b is connected to the remote monitoring panel 11 via the remote monitoring detection cable 14c. The reason why the internal pressure detection pipes 14a for detecting the internal pressure are installed at a plurality of locations (two locations in this example) in the storage tank 1 is that the internal pressure values of the storage tank 1 detected from the plurality of locations are balanced without being biased. Based on the fact that the pressure value can be detected, and even if one of the internal pressure detection pipes 14a breaks down, the other internal pressure detection pipe 14a is operated, so that the dome roof construction work can be finished as scheduled without interruption. .

  The devices that are driven and operated by electricity such as the air dome blower 6 and the electromagnetic valves 8 and 10 use a power source 15 purchased from an electric power company, but the power source 15 is an emergency generator 16 for private power generation in order to avoid troubles such as a power failure. Power is supplied to each device via the switching circuit. The air dome blower 6 connected to the power supply 15 is operated, the air supply amount in the storage tank 1 is controlled by the air supply pipe 7 and the electromagnetic valve 8, and the exhaust amount exhausted from the exhaust pipe 9 is controlled by using the electromagnetic valve 10. Maintain internal pressure.

Reference numeral 13 denotes a camera photographing means for monitoring the outer shape of the roof under construction of the dome roof. The camera photographing means 13 includes a camera 13a installed at the upper part of the measuring table 13b, and shows the photographed outer shape of the roof during construction of the dome roof as a video signal or a roof outer shape.

By being able to recognize the situation even outside the work site, it is not necessary to stay on site for 24 hours continuously, reducing the frequency of going to the site and reducing human burden.
Safety can be ensured because changes in internal pressure and abnormalities in the air dome control system can be quickly grasped. Because it is possible to realize notification by e-mail, it is possible to share information quickly and communicate quickly.

  This invention is a remote monitoring system used for construction of a dome roof for covering the upper part of a structure such as various storage tanks for storing various storage products such as liquids such as water and petroleum, low-temperature liquefied gas, digestion gas, powder, and granular materials. It can be applied to a wide range of fields such as dome roof construction.
