Cascade flood control dam based on waste tires and construction and operation method thereof

Abstract

The invention belongs to the field of water conservancy projects, and particularly relates to a cascade flood control dam based on waste tires and a construction and operation method thereof. The cascade flood control dam includes a protective net and three step dams which are sequentially arranged from upstream to downstream, the interior of each dam body is formed by stacking and connecting waste tire balancing weights, drainage holes with different heights are formed in each dam body, and each drainage hole in the upstream face of each dam body is provided with an electro-hydraulic bulkhead gate. A porous overflow hole with a plane cast iron gate is formed in the top of each dam body, transverse fixing anchor cables are arranged on the two sides of each dam body, and a foundation reinforcing structure is arranged at the bottom of each dam body. The cascade flood control dam drains water layer by layer through the drainage holes with different heights in the dam body in the flood period, and the purposes of reducing the flood peak and lowering the downstream flood control pressure are achieved. In the normal operation period, the layered water taking function is achieved by gradually opening the layer of drainage holes which are closest to the water level and can drain water. The whole cascade flood control dam is stable in engineering structure and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to a stepped flood control dam based on waste tires and its construction and operation method. Background technique [0002] Flood control is a water conservancy work that studies and adopts various countermeasures and measures according to the law of floods and characteristics of floods to prevent or mitigate flood disasters and ensure social and economic development. Its basic work content includes flood control planning, flood control construction, management and application of flood control projects, flood control, flood dispatch and arrangement, post-disaster restoration and reconstruction, etc. Flood control measures include engineering measures and non-engineering measures. Flood control is also an important professional discipline of hydraulic science. Floods often cause landslides, vegetation damage, and even traffic jams in downstream cities, casu...

AI Technical Summary

Problems solved by technology

[0003] Due to the development of technology, the high-quality and cheap synthetic rubber makes the market for tire retreading and reclaimed rubber smaller and smaller. Limited by technical level, production equipment and many other problems, it is too expensive to use tire rubber powder as raw material to produce road asphalt. , cannot be used in large quantities

Waste tires are incinerated together with other garbage to recover energy in the form of steam or electricity. Although waste tires can be disposed of in large quantities, the resource utilization rate is not high

In addition, refurbishment, production of rubber powder and reclaimed rubber, asphalt filler, and direct incineration as fuel and other treatment methods have more or less caused secondary pollution, wasted resources, and endangered residents' health. They are not the final solution.
