链轮闸门(又称履带闸门)和其他平板闸门比较,其优点是:支承摩阻力小;能将闸门承受的巨大荷载均匀地传到基础中,从而能适应大孔口高水头的运用要求.因此,尽管该门型在制造、安装和运行维修等方面都比较复杂,但仍被广泛运用在水电工程上,成为突破事故检修闸门大孔口高水头的一种有潜力的门型.表1展示了国外链轮闸门的设计水平和发展状况.

Sprocket gate (also known as track gate) compared with other flat gate, its advantages are: support friction is small; the gate can withstand the huge load evenly spread to the foundation, which can adapt to the requirements of the use of large aperture high head. Therefore, although it is more complex in terms of manufacture, installation and operation and maintenance, it is still widely used in hydropower projects and has become a promising type of door that can break the high head of large openings in accident gate. Demonstrated the design level and development of foreign sprocket gate.
