Movable sand deposition sand barrier and application method thereof

Abstract

A movable sand deposition sand barrier comprises a plurality of sand barrier plates, wherein the sand barrier plates are arranged along a sand deposition ribbon sand ridge line in a connected mode, and every two adjacent sand barrier plates are connected in a butt joint mode or a lap joint mode through a sand barrier connecting clamping pin fixing assembly. The edge of the lower end of each sand barrier plate is provided with a double-edged knife face, and the upper portion of each sand barrier plate is provided with a plurality of sets of vent holes. Each sand barrier connecting clamping pin fixing assembly comprises two connecting plates and two bolts; the left end and the right end of each connecting plate are provided with bolt through holes, every two corresponding connecting plates are arranged on the front surface and the back surface of the connecting end of every two adjacent sand barrier plates, and the bolts penetrate through the bolt through holes and the vent holes to fixedly connect every two adjacent sand barrier plates. The movable sand deposition sand barrier is mainly used for depositing drift sand and promoting a sand deposition ribbon or a sand dune to be higher and larger. When the blocked or intercepted sand is deposited to be high enough so that the sand deposition sand barrier can not effectively prevent the deposited drift sand or a sand ridge line from shifting, the sand barrier can be vertically pulled upwards or pulled out to be arranged on a new sand ridge line again to promote the sand deposition ribbon to be higher.

Description

technical field

[0001] The invention relates to a sand barrier used for desertification control, in particular to a movable sand accumulation barrier, and also relates to an application method of the movable sand accumulation sand barrier. Background technique

[0002] There have been many studies on sand barriers at home and abroad, such as clay sand barriers, firewood sand barriers, gravel sand barriers, plastic grid sand barriers, and so on. In the past, sand barriers were laid in a certain area, generally in the middle and lower part of the windward slope of the sand dunes, and had a certain effect on fixing the quicksand. The applicant and others have recently completed the national "973" project "Formation and Ecological Effects of Sand Accumulation Belt on the Edge of Hexi Oasis in Gansu Province" (Project No.: 2011CB411912). Enter the farmland, and the higher the sand accumulation belt, the stronger the protection function. The sand accumulation belt is the quicksa...
