Drainage structure for debris flow disasters
The invention provides a drainage structure for debris flow disasters, and belongs to the technical field of disaster prevention and control engineering, the drainage structure comprises a foundation base body, a diversion trench and an isolation layer, and the diversion trench is arranged on the foundation base body; the isolation layer is fixedly arranged in the diversion trench in the horizontal direction, divides the diversion trench into two diversion sub-trenches in the vertical direction, and is configured to separate the debris flow in the diversion trench, so that the water content of the debris flow in the diversion sub-trench at the lower layer is greater than that of the debris flow in the diversion sub-trench at the upper layer. According to the drainage structure for debris flow disasters, the diversion groove is divided into the upper part and the lower part through the isolation layer, debris flow water in the diversion branch groove located on the upper layer can be collected into the diversion branch groove located on the lower layer due to gravity, solid-liquid phase separation of debris flow is achieved, and the mobility of the debris flow in the diversion branch groove on the upper layer is weakened; therefore, the impact force of debris flow on the wall of the diversion trench is reduced, and the trench wall is prevented from being damaged by impact.
本公开提供一种用于泥石流灾害的排导结构，属于灾害防治工程技术领域，该排导结构包括地基基体、导流槽和隔离层，导流槽设于地基基体上；隔离层沿水平方向固设于导流槽中，隔离层将导流槽沿垂向分隔形成两个导流分槽，隔离层被配置为分隔导流槽内的泥石流，使位于下层的导流分槽的泥石流含水量大于位于上层的导流分槽的泥石流含水量。本公开提供的用于泥石流灾害的排导结构，利用隔离层将导流槽分隔形成上下两个部分，位于上层的导流分槽的泥石流水分会因重力汇集至下层的导流分槽中，实现泥石流的固液相分离，削弱了上层导流分槽的泥石流的流动性，从而有利于减小泥石流对导流槽槽壁的冲击力，避免槽壁被冲击破坏。
