Abstract

A debris flow retaining apparatus located in a debris flow active area to provide buffering retention. It includes a retaining unit anchored on a ground surface movable up and down relative to the ground surface and a buffer unit which has an air mattress located between the ground surface and the retaining unit and an air compressor to inflate the air mattress. When a debris flow occurs, the air compressor inflates the air mattress to raise the retaining unit and absorb the impact stress resulting from the impact of the debris flow to prevent the retaining unit from immediate crumpling and reduce damages caused by the debris flow.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a debris flow retaining apparatus and particularly to an apparatus that has a retaining unit cushioned by a buffering air mattress to absorb and allay the stress caused by the strong impact of debris flow to prevent immediate crumpling of the retaining unit to reduce damages. BACKGROUND OF THE INVENTION

[0002] Debris flow (also called mud slide) is a moving slurry with debris mixing up with a great amount of water in which more than half of the contents are solid substances. The solid substances contain gravel greater than sands, and stones and rock debris. It usually is caused by landslide. When there is also a heavy rainfall, the water mixes up with the rock debris and soils to become slurry, and slide or flow along the ground surface of slope lands. It could cause great damages. It is a natural disaster happened mostly in mountainous areas, especially the slope lands that are geographically unstable and where the rock...
