Description

Technical Field

[0001] The utility model relates to the technical field of cave support, in particular to a foldable cat-ear cave support device. Background Art

[0002] A cat ear cave is a battlefield anti-artillery cave. It is a protective fortification used by a single or a small number of soldiers during combat. It can effectively reduce the damage caused by the enemy's fierce artillery bombardment. They vary in size, with a small one that can only accommodate one person and a large one that can accommodate up to 3 to 4 people. The excavation of traditional cat ear caves is relatively simple. They often use the terrain to directly dig the soil from the side to open a hole. The entire inner wall of the cave is constructed with soil, but this also causes the inner wall to easily fall off, the inner side is under greater pressure, and there is a lack of support devices to support and fix it, which makes it prone to collapse. The concrete pouring support method with better anti-collapse effect is too troublesome and cannot be carried and transferred. For simple support, multiple support rods are often used to support the inner wall of the cave for point support. The force surface of this support method is too small and not comprehensive enough, and the soil layer is relatively soft, and the end of the support rod is easily pressed into the soil layer. It is not suitable for use in cat ear caves and it is difficult to achieve a support effect. Utility Model Content
