摘　　要：针对众多水闸工作闸门存在破坏隐患却无事故闸门应急抢险问题,提出在检修闸门系统的基础上构建事故闸门方案:配置能在动水中依靠自重关闭的事故闸门,借用检修门槽安装事故闸门,借用检修闸门启闭机械启闭事故闸门。验算闸门闭门力,为满足闸门闭门要求,设计事故闸门采用叠梁,适当降低单块叠梁的高度以降低水压力,行走机构采用滚轮,滚轮轴简支,在满足强度的基础上尽量降低轴直径。验算门槽轨道强度,对不符合事故闸门安装、行走条件的结构进行改造。控制事故闸门自重在启闭机械额定起重量以内,配置起吊闸门水下自动脱钩装置,并确保起升高度满足要求。设置侧滚轮,防止闸门启闭时卡阻。三河闸门槽轨道为混凝土,滚轮行走接触应力大于规范要求,因一时不能改造门槽,设计在钢滚轮外缘设置橡胶轮圈,以降低接触应力。Aiming at the problem of many working gates have potential damages but no emergency gate for emergency rescue,the scheme of emergency gate construction based on the bulkhead gate system was put forward.Disposing emergency gate which could be closed by self-weight in active water,installing emergency gate by means of overhaul gate groove,and opening and closing emergency gate by means of overhaul gate mechanical hoisting and closing accident gate.To check the closing force of gate in order to satisfy the closing requirement of gate.The overlapping beam was used in the design of emergency gate,and the height of single overlapping beam was appropriately reduced to reduce water pressure.Roller wheel was used in the walking mechanism,and the roller shaft was simply supported.On the basis of satisfying the strength,the diameter of the shaft was reduced as far as possible.The track strength of the gate groove was checked and the structure that didn’t meet the installation and running conditions of the accident gate was reformed.Controlling the self-weight of the emergency gate was within the rated lifting weight of the hoisting machinery,and equipping the underwater automatic decoupling device of the hoisting gate to ensure that the lifting height meet the requirements.Set up side rollers to prevent blockage when the gate was opened or closed.The track of Sanhe sluice gate trough was concrete,and the contact stress of the roller was greater than the standard requirement.Because the gate trough could not be reformed for a time,rubber rim was designed on the outer edge of the steel roller to reduce the contact stress.
