Description

Ship lock protective structure Technical Field The invention relates to the technical field of lock protection, in particular to a lock protection structure. Background The ship lock is a hydraulic engineering facility, mainly composed of lock chambers, upstream and downstream gates and a water delivery system, and is used for solving the navigation problem between water areas with different water levels. When the ship faces the water level drop, the ship lock can safely and stably pass through the water level barrier by adjusting the water level in the lock chamber, the water level difference in a natural or artificial water channel is overcome, and the ship is prevented from being forced to detour or unable to pass. In addition, it can also rationally regulate and control the rivers, give consideration to multiple functions such as shipping, flood control and water resource utilization. In the running process of the ship lock, the unsteady flow generated in the water filling and draining stages of the ship lock forms complex vortex and turbulence, so that the ship is difficult to keep stable under the action of irregular hydrodynamic force, the large-sized ship is easy to deflect and drift due to the influence of water flow in a limited water area, the free swinging frequency and the water flow fluctuation frequency of the large-sized ship can even generate resonance effects, the surface of the traditional lock wall is lack of effective buffering and guiding structures, if the ship collides with the lock wall, the hull plate near the waterline of the ship has deformation recess and even cracking risks, the lock room facilities face the problems of concrete stripping, steel structure deformation and the like, the maintenance frequency is obviously improved, the maintenance caused by collision accidents often needs navigation interruption, and once moderate lock wall repair can cause navigation interruption from several days to several weeks, so that the navigation congestion is caused.
