CN-121992755-A - Automatic burst type flood discharge plugging body of flood diversion gate and design method and manufacturing method thereof

Abstract

The invention relates to an automatic burst type flood discharge plugging body of a flood diversion gate, in particular to an automatic burst type flood discharge plugging body of the flood diversion gate, a design method and a manufacturing method thereof, and aims to solve the problems that the existing flood diversion gate plugging body cannot realize automatic staged opening according to water level, accurate regulation and control of discharge and both safety and economy. Therefore, the automatic burst type flood discharge plugging body of the flood diversion gate is provided with the control water level and the holes, the positions of the holes are corresponding to the height of the control water level, and the holes are internally provided with the easily-eroded bodies so as to seal the holes. According to the invention, the holes corresponding to the control water level are formed in the blocking body, and the holes are filled with the easily-eroded bodies, so that the blocking body is kept in a closed state in a non-flood diversion period, and when the flood water level reaches the preset control water level, the easily-eroded bodies can be automatically eroded by the flood water to form a flow passage, so that an automatic flood-breaking and discharging effect without external power or manual intervention is realized.

Description

Automatic burst type flood discharge plugging body of flood diversion gate and design method and manufacturing method thereof Technical Field The invention relates to an automatic burst type flood discharge plugging body of a flood diversion gate, in particular to an automatic burst type flood discharge plugging body of a flood diversion gate, and a design method and a manufacturing method thereof. Background From the prior art perspective, flood diversion engineering is a key component in flood control systems, which introduces excess flood into a stagnant flood area or flood discharge channel through a flood diversion gate to reduce the flood control pressure of main river channels and dikes. The sealing body at the flood diversion gate needs to keep a stable sealing state in a non-flood diversion period, and can be temporarily opened according to a preset water level to realize graded flood discharge when the flood is in a flood. At present, common opening modes of the plugging body mainly comprise a blasting method, a manual opening method and a gate control method. For example, the blasting method relies on preset explosives to realize structural damage, but has the problems that energy is difficult to control accurately and irreversible damage is easily caused to a main structure, the manual raking rule relies on manual operation, response is delayed and potential safety hazards are large in a flood environment, and a gate type structure has certain controllability, but usually requires complex opening and closing equipment, has higher construction and maintenance cost, and is easy to cause rust failure in a long-term operation process. Furthermore, it is difficult to achieve the safety, response timeliness, structural reliability and multi-stage leakage regulation capability in the prior art as a whole. On one hand, most schemes lack a grading flood discharge mechanism based on automatic water level triggering, so that the fine regulation and control along with the change of the water level of flood are difficult to realize, and on the other hand, the existing structure has defects in the aspects of construction complexity, operation and maintenance cost and post-disaster recovery, so that the requirements of modern flood diversion engineering on economy and sustainability are difficult to meet. Therefore, there is a need in the art for an automatic burst flood discharge plugging body for a flood diversion gate, and a design method and a manufacturing method thereof to solve the above-mentioned problems.
