Mountain torrent debris flow energy absorption buffering system and method based on Tesla one-way valve principle
The invention belongs to the technical field of disaster prevention and control, and particularly provides a torrential flood and debris flow energy absorption and buffering system and method based on the Tesla one-way valve principle, the system comprises diversion-loop structures, the diversion-loop structures are installed on the two sides of a drainage groove to form Tesla valve areas, and the Tesla one-way valve is arranged in the diversion-loop structures. The diversion-loop structure comprises an inner wall and an outer wall, a diversion port, a loop and an intersection port are formed through the inner wall and the outer wall, when slurry flows into a Tesla valve area of the drainage groove, fluid in the groove is divided into two paths at the diversion port, after one branch is shunted and flows through the loop, the branch is shunted and converged with the other branch at the intersection port, and the other branch is shunted and converged with the diversion port. The flowing directions of the two paths of fluid have certain reverse directions, and the slurry collides with each other to form motion resistance so as to reduce the motion rate of the slurry. Based on the one-way valve principle of Tesla, kinetic energy of fluid is used for energy consumption, and therefore speed reduction and disaster reduction of mountain torrents and debris flows are achieved.
本发明属于灾害防治技术领域，具体提供一种基于特斯拉单向阀原理的山洪泥石流吸能缓冲系统与方法，其中系统包括分流‑回路构筑物，所述分流‑回路构筑物安装在排导槽的两侧以形成特斯拉阀区域，所述分流‑回路构筑物包括内墙和外墙，通过所述内墙和外墙形成分流口、回路和交汇口，当浆体流入排导槽的特斯拉阀区域时，槽中流体在分流口分为两路，其中一支分流流经回路后，并在交汇口与另外一支分流汇聚，两路流体的流动方向具有一定反向，浆体之间的相互碰撞形成运动阻力，以降低浆体的运动速率。本发明基于特斯拉的单向阀原理，利用流体自身的动能进行能量的消耗，从而实现山洪、泥石流的降速与减灾。
