Abstract

The caltrop shield-shaped movable sand stabilization barrier comprises a basin-shaped iron screen and caltrop-shaped sand stabilization vegetation cat-head thorns, wherein the caltrop-shaped sand stabilization vegetation cat-head thorns are adhered to an iron screen grid, and the basin-shaped iron screen is buckled on a sand ground in an inverted mode. Because the bottom of the inverted basin-shaped iron screen is large, the upper surface of the inverted basin-shaped iron screen is arc-shaped, and in addition, the inverted basin-shaped iron screen is made of iron metal materials, the inverted basin-shaped iron screen is heavy in weight, low in position and good in wind resistance. The utility model provides a can extensive production, with low costs, draw materials easily, the sand barrier is portable, is a novel solid sand barrier who replaces traditional grass square, has extensive application prospect in prevention and treatment desertification, prevent wind the solid sand field.

Description

Shield-shaped movable sand fixing barrier for caltrops

Technical Field

The utility model belongs to the sand control and prevention device field especially relates to a movable sand fixing barrier of tribulus shield form.

Background

The wind and sand disasters are one of the main disasters in China, and are particularly serious in Xinjiang, inner Mongolia, ningxia, gansu and the like. At present, the material for fixing quicksand in desert areas is mainly common net-shaped grass square grids, wheat straw or straw with grains removed is usually used as a grass square grid raw material, the grass square grid raw material is laid on a sand dune to be in a grass square grid shape, a shovel or a grass square grid machine is used for burying the grass 15-20 cm, and the two ends of the grass are tilted and extend out of the sand surface by about 10-20 cm. Because the natural conditions in desert regions are severe, the temperature is high in the daytime, the temperature difference between day and night is large, the wind and sand damage is strong, and the common grass grid sand barriers are easy to rot and destroy within one to two years, and lose the sand fixing effect. Moreover, the sand fixation of the netted grass square grid is only limited in a fixed sand fixation range, and the fixation effect on moving quicksand is poor.

Chinese patent No. 201921533463.9 discloses a movable arched net cage type sand barrier, which comprises a fixed frame, arched support bars, a ventilation net cage and insertion fixing piles, wherein the arched support bars are connected with the fixed frame, the insertion fixing piles capable of being inserted into sand are connected with four corners of the fixed frame, and the ventilation net cage is arranged on the arched support bars. The sand-blocking barrier has a good sand-fixing effect, but because the arch-shaped net cage is higher in position, some unstable sand-blocking barriers are easy to blow away by wind under the condition of large wind power, and the sand-fixing effect is reduced.

Disclosure of Invention

The utility model aims at solving the problems of the prior sand blocking and fixing device, and provides a movable sand fixing barrier with a caltrop shield shape, which has simple structure and is economical and practical.

The technical scheme of the utility model is like this: the puncture-proof movable sand-fixing barrier comprises a basin-shaped iron screen and puncture-proof punctures of puncture-proof vegetation, the puncture-proof punctures of puncture-proof vegetation are bonded on the iron screen, and the basin-shaped iron screen is buckled on the sand. Because the bottom of the inverted basin-shaped iron screen is large, the upper surface of the inverted basin-shaped iron screen is arc-shaped, and in addition, the inverted basin-shaped iron screen is made of iron metal materials, the inverted basin-shaped iron screen is heavy in weight, low in position and good in wind resistance.

Has the beneficial effects that: the utility model provides a can extensive production, with low costs, draw materials easily, the sand barrier is portable, is a novel solid sand barrier who replaces traditional grass square, has extensive application prospect in prevention and treatment desertification, prevent wind the solid sand field.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1-basin-shaped iron screen mesh and 2-caltrop-shaped sand-fixing vegetation cat-head thorn.

Detailed Description

In order to make the embodiments of the present invention more clear, the following embodiments are further described with reference to the following examples.

Example 1: referring to fig. 1, the tribulus shield-shaped movable sand-fixing barrier comprises a basin-shaped iron screen 1 and tribulus-shaped sand-fixing vegetation cathead 2, the tribulus-shaped sand-fixing vegetation cathead 2 is adhered to an iron screen grid, the basin-shaped iron screen 1 is buckled on the sand, the diameter of the bottom width of the basin-shaped iron screen 1 is 40-50cm, and the height of the basin-shaped iron screen 1 is 10-12cm. The mesh number of the basin-shaped iron screen 1 is 60-80 meshes, and the ventilation rate is 40-60%. The lower basin-shaped iron screen 1 is in an iron shield-shaped structure and plays a role of a fixed framework; the caltrop-shaped sand-fixing vegetation cat-head thorn 2 above simulates field sand-fixing vegetation plants, and plays a role in preventing wind and fixing sand by applying the bionics principle.

The sand stabilization barrier is arranged according to the shape of a sand dune in a partitioning mode, one partitioning area is 200 meters long and 200 meters wide, and the distance between the tribulus shield-shaped movable sand stabilization barriers arranged in each partitioning area is 2 meters. And according to the moving condition of the quicksand, removing the original part of the sand fixing barriers, and replacing the original part of the sand fixing barriers with the areas needing sand fixing for reinstallation and placement.

The utility model discloses simple structure, convenient to use is placed in the installation, and the sand fixation barrier material is all very cheap with the cost of manufacture, suitable large tracts of land in desert area is promoted.
