Combined water stop system suitable for underwater dry environment operation equipment

Technical Field

The utility model relates to a hydraulic engineering pivot safety removes dangerous reinforcement technical field, and the more specifically combination formula intelligence stagnant water equipment that is applicable to concrete contact surface dry chamber cabin restoration equipment under water that says so.

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 is an important guarantee for well exerting the functions of power generation, flood control, irrigation and the like, and the flood control promotion engineering needs to be implemented, the weak flood control links are solved, the danger removal and reinforcement work and research of the hydraulic engineering hub are enhanced, and the flood control and disaster reduction functions of the hydraulic engineering are improved in the fourteenth five-year planning and 2035 long-term view target compendium of the national economy and social development of the people's republic of China.

The flood discharge energy dissipation buildings of the hydraulic engineering mainly comprise overflow dams (roads), plunge pools, discharge tunnels, hydraulic gates and the like, bear huge high-speed water flow impact force when a hydropower station runs to discharge flood, and a concrete bottom plate of the buildings is very easy to be damaged by scouring, cavitation erosion, abrasion, vibration damage, bottom plate splitting, cracking and the like. After the bottom plate is damaged, huge water flow impact can continuously wash the building foundation, and the dam foundation can be directly damaged seriously. According to statistics, nearly 40% of flood discharge and energy dissipation buildings of hydraulic engineering at home and abroad are damaged in different degrees. In engineering practice, once the drainage structure is damaged, the safety operation of the whole hydraulic engineering is a huge hidden danger, major safety accidents such as dam break and the like are easily caused along with continuous scouring of the foundation, and the life and property safety of downstream cities and people is seriously threatened.

In the existing research and engineering practice, two repair methods are adopted for the damaged stilling pool bottom plate: dry land operation repair and direct underwater repair. But both of these repair methods have major drawbacks. The dry land operation repair needs to pump out all water in the stilling pool, which is long in time consumption and huge in cost; the direct underwater repair of the damaged surface which needs underwater treatment has great technical difficulty, high cost and poor treatment effect. Therefore, the research team provides the dry land repair equipment for the underwater concrete damage, the equipment can create a local dry land environment, and the problems of the two prior arts are well solved.

However, the creation of a local dry land environment requires the sealing between repair equipment and underwater concrete, and how to make water stop is a technical problem. In the application of the prior art, rubber water stopping or rubber air cushion water stopping is mostly adopted, and the technology is largely adopted on a hydraulic gate, so that a better water stopping effect is 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, and the contact surface of the underwater repair equipment is a non-smooth concrete surface, the problem that complete sealing cannot be achieved by only adopting rubber water stop exists, and part of water penetrates through the rubber water stop to enter the repair equipment, so that the difficulty of creating dry construction conditions is caused. By adopting a single water stopping method, a good water stopping effect cannot be achieved. The problem that the underwater repair equipment cannot be completely sealed due to the fact that only rubber water stopping and non-smooth concrete surface contact water stopping are adopted, and partial water penetrates through the rubber water stopping and then enters the repair equipment, so that the difficulty of creating dry construction conditions greatly reduces the practicability and the applicability of the underwater repair equipment.
