摘要:
为使拦船设施适应水位变化,研究采取以下措施:一是选择在设计低水位时安装拦船设施,选配适当体积和重量的浮筒,调整钢丝绳到水面的间距以适合拦阻船舶; 二是在设计低水位时两岸水边的2只浮筒下加大配重,安装时收紧钢丝绳,分配适当重量由钢丝绳承担,使钢丝绳内具有设计张力; 三是引入由底板、构架、钢丝绳、滑轮组、吊锤、导向钢管等组成的张拉系统,其中钢丝绳一头连着设计低水位时拦船设施水边的浮筒,另一头通过3个滑轮连接吊锤。前两项措施保证拦船设施在设计低水位下正常发挥拦船功效,第三项措施保证水位上涨后,张拉系统吸收拦船设施富余钢丝绳,并以几乎恒定的拉力使拦船设施钢丝绳处于张紧状态,发挥拦阻船舶作用。安装时通过调整钢丝绳长度、浮筒配重、吊锤重量等措施,使拦船设施在任何水位下均满足设计要求。
Abstract:
In order to adapt the ship-blocking facilities to the changes of water level, the following three measures were taken: First, installing ship-blocking facilities at lowest design water level, selecting the buoys of appropriate volume and weight, adjusting the distance between wire rope and water surface to be suitable for blocking ships; Second, increasing the counterweight of two buoys at both sides of the river under lowest design water level, tightening the wire rope when installing, and assigning appropriate weight borne by the wire rope, so as to make the wire rope bear the design tension; Third, a tensed-tension system composed of bottom plate, frame, wire rope, pulley block, hanging hammer, guiding steel pipe, etc. was introduced. One end of the wire rope was connected to the buoy at the water side of the ship blocking facility at the lowest design water level, and the other end was connected to the hanging hammer through three pulleys. The first two measures ensured the normal function of the ship-blocking facilities at lowest design water level. The third measure ensured that after the water level rose, the tension system absorbs the surplus steel wire rope of the ship-blocking facilities and tensioned the steel wire rope with almost constant tension to play the role of blocking ships. When installation, by adjusting the length of wire rope, the counterweight of buoys and the weight of hanging hammers, the ship-blocking facilities could meet the design requirements at any water level.
