Bridge pier protection method capable of resisting multistage impact of debris flow
The invention discloses a bridge pier protection method capable of resisting multistage impact of debris flow, which comprises the following steps of: 1, determining the structural type of a bridge pier according to actual engineering design, and judging the basic characteristics of the debris flow at the position of the bridge pier through field investigation and data combination and experiments; 2, the size and number of RC columns arranged around the pier and the distance between the RC columns and the pier are calculated; 3, waste tires and wood boards which are convenient to disassemble and have a buffering effect are arranged on the outer sides of the RC columns, and relevant parameters are calculated; 4, a protective net is arranged on the inner side of the RC column; through calculation and arrangement of the bridge pier protection device according with debris flow characteristics, on the basis of effectively protecting the bridge pier from being impacted and damaged by debris flow, resources are saved, the engineering cost is effectively reduced, the waste tires are used as the buffering parts of the RC columns, rigid impact between stones in the debris flow and the RC columns can be effectively avoided, and the service life of the RC columns is prolonged. The service life is long, disassembly and replacement are convenient, and maintenance cost is low.
本发明公开了一种抗泥石流多级冲击的桥墩防护方法，包括以下步骤：1：根据实际工程设计明确桥墩的结构型式，再经现场实地调查和结合资料、实验判定桥墩所处位置的泥石流基本特征；2：计算桥墩四周布置的RC柱的尺寸、数量和RC柱与桥墩之间的间距；3：在RC柱外侧设置方便拆卸和具有缓冲作用的废旧轮胎和木板，并计算相关参数；4：在RC柱内侧设置防护网；本发明通过计算，设置符合泥石流特征的桥墩防护装置，在有效保护桥墩不被泥石流冲击损坏的基础上，节约了资源，有效降低工程成本，且本发明利用废旧轮胎作为RC柱的缓冲部，能有效避免泥石流中的石块与RC柱刚性撞击，使用寿命长便于拆卸更换，维护成本低。
