Description
Technical Field
The invention relates to the technical field of hydraulic engineering hub safety danger removal reinforcement, in particular to an intelligent water stopping method suitable for underwater dry chamber cabin repair equipment.
Background
The safety problem of the hydraulic engineering hub is always a very concerned problem of the country, the society and people, whether the hydraulic engineering hub can safely and stably operate or not, is an important guarantee for good exertion of functions such as power generation, flood control and irrigation, and aims to implement flood control lifting engineering, solve flood control weak links, strengthen the work and research of the flood control and reinforcement of the hydraulic engineering hub and improve the flood control and disaster reduction functions of the hydraulic engineering.
The flood discharge and energy dissipation building of hydraulic engineering mainly comprises overflow dams (channels), plunge ponds, spillway holes, hydraulic gates and the like, and when the building runs and discharges floods in hydropower stations, huge high-speed water flow impact force is born, and concrete bottom plates of the building are easily damaged by scouring, cavitation erosion, abrasion, vibration damage, bottom plate splitting, fracture and the like. After the bottom plate is damaged, huge water flow impact can wash the building foundation continuously, and the dam foundation can be damaged directly seriously. According to statistics, flood discharge energy dissipation buildings with approximately 40% of hydraulic engineering at home and abroad are damaged to different degrees. In engineering practice, once the drainage structure is destroyed, the safe operation of the whole hydraulic engineering is a huge hidden trouble, and along with continuous washing of the foundation, serious safety accidents such as dam break and the like are extremely easy to be caused, and the life and property safety of downstream cities and people is seriously threatened.
In the existing research and engineering practice, two repair modes are adopted for the damaged bottom plate of the absorption basin: and (5) performing dry land operation repair and direct underwater repair. However, both of these repair methods have major drawbacks. The dry land operation repair needs to pump out all water in the stilling pool, and has long time consumption and huge cost; the damage surface is required to be treated underwater in direct underwater repair, the technical difficulty is high, the cost is high, and the treatment effect is poor. Therefore, the team provides the equipment for repairing the damaged dry land of the underwater concrete, which can create a local dry land environment and well solve the two defects in the prior art.
However, creating a local dry environment requires making a seal between the repair equipment and the underwater concrete, and how to make a water stop is a technical problem. In the prior art, rubber water stop or rubber air cushion water stop is mostly adopted, and the technology is largely adopted on hydraulic gates, so that a good water stop effect is also obtained. However, because the working environment of the hydraulic gate is different from that of the repair equipment, the water stop contact surface of the hydraulic gate is a smooth steel plate surface, the contact surface of the underwater repair equipment is a non-smooth concrete surface, the problem that the water stop cannot be completely sealed can be caused by simply adopting rubber, and part of water can enter the repair equipment through the rubber water stop, so that the difficulty of creating dry construction conditions is caused.

3. The intelligent water stopping method suitable for underwater dry chamber cabin repair equipment according to claim 1, wherein the method comprises the following steps: the remote intelligent control terminal comprises a microcomputer, a remote camera, an underwater signal transmitter and a satellite positioning system, and performs information interaction with an external remote control center through the underwater signal transmitter, so that the hydraulic station is started to push the hydraulic cylinder according to a specific instruction of the external remote control center, and the first-stage waterproof electromagnetic valve, the second-stage waterproof electromagnetic valve and the third-stage waterproof electromagnetic valve are opened and closed.
4. The intelligent water stopping method suitable for underwater dry chamber cabin repair equipment according to claim 1, wherein the method comprises the following steps: the P-type water stop, the omega-type water stop, the flexible film bag water stop and the I-type water stop are fixed on the skirt board of the repair equipment body through fastening bolts, and the water stop is a combination of common rubber water stop and flexible film bag water stop; the P-type water stop, the omega-type water stop and the I-type water stop are rubber water stops, the flexible membrane bag water stops are flexible materials, the flexibility and the plasticity are strong, and water stop materials are filled in the flexible membrane bag water stops; the water stopping effect is exerted as a result of the synergistic effect of the water stopping form and the coarse particle gel filling slurry, the medium particle gel filling slurry and the fine particle gel filling slurry.
