Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the rock dam can only block part of the rolling stones, and the debris flow often carries a large amount of sediment, and still has a large impulse, with a large impulse and carries more mud Sand mudslides still have great destructive power on buildings, and will cause damage to roads and village construction facilities under the rock barrage

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] refer to figure 1 with figure 2, is a kind of debris flow prevention and control system disclosed in this embodiment, including a rock blocking structure, a sand blocking structure, an energy dissipation and sedimentation structure, and a flow diversion structure arranged sequentially along the mountain slope from top to bottom. In mountainous areas prone to debris flow, trenches are excavated on the mountain body in areas where debris flow is prone to occur, so that the inclination angle between the bottom of the trench and the horizontal plane gradually decreases. Larger rolling stones are intercepted to reduce the contents carried by the debris flow, and a large amount of sand and stones carried in the debris flow are partially intercepted through the sand blocking structure, so as to reduce the contents of the debris flow and reduce the impact fo...

Abstract

The present invention relates to the technical field of debris flow prevention and control facilities, in particular to a debris flow prevention and control system, comprising: a groove arranged on the mountain body, and stone barriers arranged in the groove along the slope of the mountain body from top to bottom sequentially for intercepting rolling stones Structure; sand-retaining structure for intercepting sediment; energy-dissipating sedimentation structure for slowing down the velocity of debris flow; diversion structure for guiding the discharge of debris flow. The invention has the effect of reducing the energy and sand carried by the mud-rock flow to reduce the damage of the mud-rock flow to roads, villages and other construction facilities.

Description

technical field [0001] The invention relates to the technical field of debris flow prevention and control facilities, in particular to a debris flow prevention and control system. Background technique [0002] Debris flow is a torrent of mixed concrete and sandstone formed by heavy rain and floods scouring mountains containing sand and gravel. It is a geological disaster that often occurs in mountainous areas. Debris flow has suddenness, fast flow, large flow, large material capacity, and strong destructive power. Therefore, mudslides often destroy roads, railways, villages and towns, causing huge losses. [0003] At present, in the debris flow prevention and control project, a mountain trench is generally excavated along the slope of the mountain between the mountains prone to debris flow, and then a rock dam is built in the mountain ditch to block the debris flow along the mountain through the rock dam. To reduce the impact of debris flow on the building, in the preventio...
