国内外的中、低水头船闸大多采用集中(头部)输水系统。根据水头不同,常用的有闸门上孔口输水、门下输水、短廊道输水、门缝输水等形式。这些集中输水系统的代表形式,虽然在消能方式上常有不同的改进,但未见有重大的突破。六十年代开始研究槛下输水系统。槛下输水系统是在门槛下沿着口门全宽的闸首底 At home and abroad most of the low-head locks are mostly concentrated (head) water delivery system. According to the different head, commonly used in the gate port water, water under the door, short corridor water, door water and other forms. Although the representative forms of these centralized water conveyance systems often have different improvements in energy dissipation modes, no major breakthroughs have been made. In the sixties began to study under the water transport system. Under the threshold of the water delivery system is along the gate under the gate width of the gate at the end of the first
