Abstract:Aiming at the problem of initial accident rainwater collection in goods loading and unloading area of Luojing container terminal,the initial rainwater collection scheme and its influence on the terminal are studied.The collection schemes of initial rainwater confluence from both sides to the middle and from the middle to both sides are designed.The comparative analysis method is used to qualitatively compare the effects of the two schemes on drainage function,usage function,hydraulic structure and cost investment.The research shows that the water collection scheme from both sides to the middle realizes the efficient collection and automatic collection management of the initial rainwater gravity flow through the design of the double drainage ditch in the middle.The structure layout is simple,but the cover plate of the double drainage ditch in the middle has a certain influence on the driving of the vehicle.The water collection scheme from the middle to both sides is arranged through the three drainage channels of the front,middle and rear.Although the influence of the cover plate of the middle drainage ditch on the driving of the vehicle is reduced,the scheme of collecting water is complicated due to the shortage of the front space.Whether it is the manual collection of the sewage vehicle scattered in the collecting pool or the continuous water collection design that increasing the distance between the front rail and the front line of the wharf,they are faced with the problems of reduced water collection efficiency,increased structural complexity,potential loading and unloading capacity and limited efficiency.The two water collection schemes only affect the detailed structure of the wharf,and the cost can be ignored compared with the wharf investment.This study shows the importance of initial rainwater collection and structural collaborative design of high-pile beam-slab wharf,and provides reference for subsequent similar wharf design.
