Movable shunting blocking system for debris flow prevention and control

Abstract

The invention relates to a movable shunting blocking system for debris flow prevention and control. The blocking system comprises a desilting shunting dam, two movable flow guiding mechanisms, an energy dissipation blocking dam and an intercepting dam; and the debris flow is divided into two strands by the desilting shunting dam and then is subjected to secondary shunting and desilting under the guidance of the movable flow guiding mechanisms, the energy dissipation blocking dam is used for dividing the debris flow into two strands, guiding the two strands of debris flow to form convection currents which flow to the intersecting direction, and then turbulent flow is formed through hedging during intersection so as to dissipate the energy of the debris flow. According to movable shunting blocking system for debris flow prevention and control in the invention, a multi-level and multi-functional elastic prevention and control mechanism composed of the movable shunting dam, the energy dissipation blocking dam and the intercepting dam is established in a flow channel where the debris flow happens frequently to carry out elastic interception, partial interception, region retention and deceleration energy dissipation on the debris flow, so that the impact force and the damage property of the debris flow are greatly reduced; and the blocking system is high in anti-geological disaster capability, and even if part of damage occurs, the prevention and treatment effect is not seriously affected.

AI Technical Summary

Benefits of technology

This patented technology describes various technical features for creating an effective and reliable way to prevent damage caused from heavy objects or other sources during transport operations without causing significant negative consequences like environmental pollution. It uses multiple layers of materials called diodes and trivalve structures to absorb shock waves while allowing them to separate before being stopped. A slurry accumulation region prevents further movement of degradants and reduces their impact upon surrounding areas. Different types of blocks made of different material may include tungsten carbons, tantum cars, zinc diode bars, rubble shieldings, and ballistic resistant systems. Overall, this innovative design helps improve safety measures against threatening events involving high levels of force and potential harmful environments.

Problems solved by technology

Technological Problem: Debris Flow (DF) describes an issue related to road safety during severe weather events like droughts or fires. DF can cause significant loss if there're no effective way to stop this phenomenon effectively without rebuilding these structures afterwards. Current solutions involve constructing temporary barriers around specific locations within roads/rail systems but they have limitations because their design may lead to poorly designed protection measures.
