Description

Novel low-cost sand-fixing and controlling method

Technical Field

The invention relates to a novel low-cost sand fixation and control method, in particular to a low-cost honeycomb regenerated paperboard sand fixation and control method applied to desertification or desertification control.

Background

By the end of 2009, the desertified land area in the country is 173.11 ten thousand square kilometers, occupies 18.03 percent of the total area of the national soil, and is distributed in 902 counties (flags and districts) of 30 provinces (autonomous regions and direct prefectures) except Shanghai, Taiwan and hong Kong and Australian special administrative districts. China is the world with the largest desertification area and 31 ten thousand square kilometers of land with obvious desertification trend. The desertification land of local areas such as northwest Sichuan and downstream of Tarim river is still expanded. The vegetation in the desert area in northern China is still in the initial recovery stage generally, the self-regulation capability is still weak, the stability is still poor, and a stable ecological system is difficult to form in a short period. The negative effects of human activities on desert vegetation are not eliminated, and vegetation damage behaviors such as overloading grazing, blind reclamation, excessive mining and digging, unreasonable utilization of water resources and the like still exist. Extreme meteorological disasters (such as continuous drought and the like) frequently occur due to climate change, the influence on vegetation construction and restoration is great, and the danger of land desertification and desertification still exists.

In recent years, a plurality of new technologies are applied in the aspect of sand stabilization and control, such as a high vertical sand barrier, a sand stabilization grid and a low vertical sand barrier. The high vertical sand barrier is generally made of steel plate meshes, plastic meshes or concrete vertical plates and the like, so that the construction cost is relatively high, the environment is seriously influenced, and the maintenance cost is also high. In addition, the sand-fixing grids also comprise grass grids made of reeds and straws, stone grids made of cobblestones, geotechnical material grids made of plastic woven nets and the like, the grass grids and the stone grids highly depend on local resources, the long-distance transportation cost is too high, a large amount of labor requirements are fatal weaknesses, and the plastic woven nets are blown by strong wind due to aging, fly everywhere and are difficult to degrade, so that serious environmental problems are caused.

The main problems of the traditional method are as follows:

firstly, the preparation is complicated with high costs, is unfavorable for the large tracts of land to administer and uses.

And secondly, the raw materials are not naturally degradable materials, so that the environment is polluted while the environment is controlled, and the loss is avoided.

Disclosure of Invention

The invention relates to a novel low-cost paper sand-fixing and controlling method, in particular to a low-cost honeycomb-shaped regenerated paperboard sand-fixing and controlling method applied to desertification or desertification control. The invention adopts a honeycomb structure, has simple structure, uses the recycled paper board as the material, can be folded and is convenient for mass transportation. The production and transportation cost is low, the material can be naturally degraded, and the environment can not be polluted.

In order to achieve the purpose, the invention adopts the following technical scheme:

the method for fixing and controlling the sand uses the regenerated paper board to manufacture a hexagonal honeycomb hollow cylinder model with the height of 20CM and the length of a hexagonal single side of 10CM, or the height of 40CM and the length of a hexagonal single side of 30 CM. (the height and the length of the six sides are not limited to the two specifications according to the requirements of the planted plants).

The recycled paperboard structure can adopt a honeycomb sandwich structure or a similar structure, so that the rigidity and the strength of the material are improved.

The bottom of the hexagonal main body structure is respectively extended with a 'foot' which has the same length with the bottom edge and the width of 5CM-10CM, and the 'foot' is a protection plate playing a role of fixing, and is called as a 'fixing protection plate' for short.

The fixing guard plate is inserted into the sand body to be unfolded back, and the fixing guard plate is pressed by sand, so that the device can be prevented from being blown away by strong wind, and the wind-proof fixing effect is achieved.

The novel low-cost paper sand fixation and control method can be a single hexagonal hollow structure cylinder or a connected structure of a plurality of hexagonal hollow structure cylinders.

The beneficial effects of the invention patent can be summarized as follows:

1. this patent uses the regeneration cardboard to avoid traditional sand fixation device material to the secondary pollution of environment.

2. The sand stabilizing device has the advantages of simple structure, small size after folding, mature production technology, convenient large-scale manufacturing, transportation and installation, low cost, good sand stabilizing effect, capability of naturally degrading materials without secondary pollution to the environment, and high popularization and application values.

The main body structure of the hexagonal hollow structure cylinder 1 is made of a recycled paperboard, and a honeycomb sandwich reinforced structure is arranged inside the recycled paperboard. The hexagonal main body structure has the height of 20CM and the length of a hexagonal single side of 10CM, or the height of 40CM and the length of a hexagonal single side of 30 CM. (the height and the length of the six sides are adjusted according to the growth size of the planted plants, including but not limited to the two specifications).

And 2, the fixed guard plate is connected with the hexagonal column main body structure. The bottom of the 2 hexagons extends to form a width of 5CM-10CM (the fixed guard plate can be adjusted in size according to actual needs, including but not limited to the above sizes).
