The invention provides a movable flood bank which comprises a base, a rotating part and a tension device, the rotating part is rotatably connected with the base, and the rotating part can be switched between a water shifting state and a lying state under the action of external force; one end of the tension device is rotatably connected with the upstream face of the rotating part, the other end of the tension device is rotatably connected with a base on the upstream side of the rotating part, the tension device comprises a plurality of tension pieces, and the tension pieces are rotatably connected, so that the tension device is tensioned or folded; when the rotating part is in the water retaining state, the gravity center of the rotating part is located on the backwater side of the rotating position, and the tension device is tensioned; and when the rotating part rotates to a lying state, the tension pieces rotate relatively to fold the tension device. The movable flood bank provided by the invention has a relatively simplified structure, and is reasonable in stress and relatively high in stability; a large containing groove does not need to be formed, so that the construction cost and the engineering cost are saved.
本发明提供了一种活动防洪堤，包括基底、旋转部和拉力装置，旋转部和基底可转动连接，旋转部可在外力作用下切换挡水状态和卧倒状态；所述拉力装置的一端与旋转部的迎水面可转动连接，另一端与旋转部迎水侧的基底可转动连接，拉力装置包括若干拉力件，各个拉力件之间可转动连接，从而使拉力装置拉紧或者折叠；当旋转部处于挡水状态时，旋转部的重心位于转动处的背水侧，拉力装置拉紧；当旋转部转动至卧倒状态时，各个拉力件之间相对转动使拉力装置折叠。本发明提供的活动防洪堤具有较为简化的结构，并且受力合理，稳定性较高；无需开设大型容置凹槽，节省了施工成本和工程造价。
