Light and convenient combined type sand-protecting barrier used for fixing shifting sand

Abstract

The invention relates to a portable combined sand barrier fixed by quicksand, which includes a fixing mechanism and a sand barrier mechanism: the fixing mechanism includes a fixing sleeve and a fixing rod, and the fixing sleeve is provided with 4 locking slots, each of which is 90° to each other. The middle of the fixing sleeve is hollow, and the fixing rod is passed through the middle of the fixing sleeve to the sand surface to achieve the fixing effect; the sand barrier mechanism includes fiber material and two bayonet pins, and the bayonet pins are snapped into the slot of the fixing mechanism, and the bayonet A fixing plate is arranged on the pin, and the fiber material is fixed on the fixing plate. The advantages of the present invention are as follows: when working in the field, the present invention can quickly assemble and start work, save time and effort, and is easy to operate, which not only improves work efficiency, but also reduces investigation costs. Strong anti-aging, can be used many times, can be quickly disassembled when not in use, can be put into a bag or toolbox, and is easy to carry. It can effectively strengthen the sand surface or weaken the wind force near the surface, and has a greater interception effect on the transiting quicksand.

Description

technical field [0001] The invention relates to the technical field of wind prevention and sand control, in particular to a portable combined sand barrier with quicksand fixed. Background technique [0002] Chinese patent CN200420085833.4 discloses a combined porous gypsum board sand-fixing barrier for sand damage control, which is formed by embedding two groups of gypsum boards with slightly different structures. One of the gypsum boards has a notch in the middle of one side, and small holes that are alternately displaced in the upper half. The other gypsum board also has a notch in the middle of one side, and small holes that are alternately displaced in the lower half. Insert the notch of a gypsum board Another gypsum board notch, in the shape of a cross. Multiple groups of gypsum boards are embedded and connected to form a grid-like sand-fixing barrier. However, its disadvantages are that the operation speed is slow, the combination is inconvenient, time-consuming and ...
