Recently, affected by the typhoon, many places have met with extreme heavy rainfall. The rare continuous heavy rainfall caused engineering danger and urban waterlogging. Also, it have given big affect to the urban railway, highway and civil aviation traffic. In order to enhance urban flood control and drainage capacity, we must constantly summarize the experiences and lessons to make up for the key shortcomings of flood control and drainage. Currently, the pneumatic spillway gate solution implemented by Sunny Rubber Co., Ltd. of Bright Stone Technology Group have attracted big concern about urban landscape waterlogging control.
Yuyao is located in the low-lying area of the plain. Its mother river, Yaojiang River, has passed through the city from west to east. The congenital geographical conditions have caused the drainage capacity of Yaojiang River to be weaker than that of other rivers under the same flow rate.
In order to eliminate the flood-prone area and build a safe dam for the people, Yuyao City and Sonny Rubber Company collaborate well hand in hand. The Eco-friendly air bag support dam ( or called as pneumatic spillway gate) has been adopted on the outside of Lanjiang Square to solve the waterlogging problem. The project is 180 m long, consisting of 36 groups of ecological air bag support dams, which will integrally rise and descend. It is located outside the sidewalk to play the significant role of urban flood control and waterlogging prevention.
After the flood: The support air bladders will deflate. And exhaust, the shield steel panel will collapse into the prefabricated shield groove. At this time, the top of the collapsed shield and the sidewalk will be blended into one entirety to avoid of blocking passing through. By laying the plastic on the surface, the pedestrians will walk on the ground, without hard feeling.
The air bladder of the Eco-friendly air bag support dam is made of special rubber, with aging resistance performance for more than 30 years. The water retaining height after inflating is 1 meter. of the inflatable dam body is 1 m, which can meet control standard of 50 years a meet of flood. The inflation can be completed within 20 minutes
Nearly ten years ago, entrusted by the market customers, Sunny Rubber Co., Ltd. have made deep analysis and development about the principle, structure, performance and materials of the pneumatic spillway gate. Based on the foreign technology, we have made innovation and improvement for the air bladder forming and theoretical calculation problems. Further more, we successfully made innovative breakthrough in vulcanization process. Relying on this, we have successfully developed 2m and 6m height spillway gate, which have been identified in both domestic and broad customers’ site.
The development and successful production of pneumatic spillway gate has made Sunny Rubber Co., Ltd. take a solid step in the field of air bag support dam. And it will lay the foundation for the overseas market layout of the Group's business in the future.
