灌区上水的精准计量是一件关乎灌区向好发展的大事。陆浑灌区总干渠的内埠分水枢纽(简称内埠分水闸)就直接担负着向东一干渠、东二干渠调配水的任务。由于在通水期内埠分水闸闸门启闭频繁,各种闸前水位和闸门开度及闸后水位均影响到闸孔的过流量,通过分水闸的长期实际运用观测,对闸孔过流问题有了更好的认识,方便今日的运用管理。
The precise metering of Sheung Shui in the irrigation area is a major event concerning the development of the irrigation area. Luhun irrigated main port of the main port within the port water diversion hub (referred to as the port sub-gate) is directly responsible for the east to the main canal, the second trunk canal deployment of water task. Due to the frequent opening and closing of sluice gate in the port during the flood period, the over flow of the sluice hole is influenced by the gate level and gate opening and the water level after sluice. Through long-term practical observation of the sluice, The problem has a better understanding, to facilitate the operation and management of today.
