Problems solved by technology

Debris flow dam due to neglect of maintenance, resulting in reduced storage capacity and increased risk
The retaining dam intercepts a large amount of earth and stone, and will be under great pressure. When the pressure reaches the limit of the structure, the dam may collapse, causing even greater disasters

Abstract

The invention discloses a debris flow ecological protection device capable of dissipating energy and conducting filtration. The debris flow ecological protection device comprises at least debris flow ecological protection unit located on the upstream surface. Each debris flow ecological protection unit comprises a plurality of megalith gabion layers and slide-resistant piles linearly arranged. Each megalith gabion layer comprises a plurality of megaliths. The slide-resistant piles are arranged behind the last megalith gabion layer. Crash pads are arranged between the slide-resistant piles and the last megalith gabion layer. In the debris flow direction, the megalith gabion layers of each debris flow ecological protection unit are arranged in a ladder mode and are elevated gradually. The megaliths of each debris flow ecological protection unit are connected into a whole through concrete. According to the debris flow ecological protection device, debris flow energy can be weakened stepwise, and big rock blocks can be filtered, so that debris flow is restored to normal water flow.

Description

technical field [0001] The invention belongs to the field of mud-rock flow control, and in particular relates to an energy-dissipating and filtering mud-rock flow ecological protection device. Background technique [0002] Debris flow disasters are one of the important types of geological disasters in my country, and they are listed as three major geological disasters together with collapses and landslides. With the expansion of the road network and railway network and the acceleration of urban construction in mountainous areas, the impact of mudslides in mountainous areas has become more serious. In particular, the devastating mudslide in Zhouqu, Gansu Province has killed more than 1,700 people. Since then, the prevention and control of mudslides has attracted much attention. [0003] The danger of mudslides is that the high-speed water carries a large amount of sand and stones, which has a long transmission distance, a wide range of influence, and great destructive power. ...
