Abstract

This design is for the basic design of the Second Line Shiplock of the West Hub of Dazhi River. Considering the social economic and natural conditions, the overall layout and preliminary planning of the ship lock are taken into consideration on the premise of ensuring the safety and the ability to pass, with the selection of the location of the ship lock, the elevation and layout of the navigation channel, the ship lock, and the ship lock. The water consumption and the calculation of the capacity are selected; the structural types of the various parts of the lock are selected; the preliminary design of the water conveyance system, such as the hydraulic calculation, the determination of the size of the corridor and the type selection, etc.; finally, the calculation of the upper gate structure, the calculation of the load, the checking of the stability and the calculation of the reinforcement of the floor. The design and calculation of the design are carried out according to the current specifications, so as to achieve the goal of the basic design of the ship lock and meet the requirements of the task book.
