Sand-proof otter board, printed pile and sand-proof otter lattice

Abstract

The sand-proof otter board includes sand-proof net, net frame and T-shaped nose. The pointed pile includes upper cylinder, lower cone, and the cylinder has 1-8 T-shaped slots corresponding to the T-shaped noses in the sand-proof otter board. The sand-proof otter lattice is one combination of at least one sand-proof otter board and at least two pointed piles. The sand-proof otter lattice is used in fixing yellow sand on sides of railway and highway and around oil field and building to resist sand of storm invasion in desert.

Description

technical field [0001] This patent relates to a picket pile and a sand-blocking grid, in particular to a pile-type combined sand-blocking grid. The sand-blocking grid is used to block or fix yellow sand. The sand-blocking grid can be used especially in desert areas On both sides of roads and railways, around oil fields and buildings, so that they are not damaged by wind and sand, and ensure the smooth flow of roads and the safety of buildings. Background technique [0002] China has a vast territory, and there are large deserts in the northwest and northeast regions. With the development of the economy and the needs of the military industry, it is necessary to build railways, roads, houses, satellite launch sites, oil fields, etc. in the desert, and the raging wind and sand If it is not blocked or fixed, it will bury railways, highways and buildings, seriously affecting personal safety and traffic safety.

Problems solved by technology

[0002] China has a vast territory, and there are large deserts in the northwest and northeast regions. With the development of the economy and the needs of the military industry, it is necessary to build railways, roads, houses, satellite launch sites, oil fields, etc. in the desert, and the raging wind and sand If it is not blocked or fixed, it will bury railways, roads and buildings, seriously affecting personal safety and traffic safety

[0003] In the past, people used wheat straws to weave into square circles. After being arranged and combined, they were placed beside the road to block sand, and the effect was acceptable. With the structural adjustment of crops, the amount of straw available is decreasing

[0004] At present, some people try to drill holes in gypsum boards to form sand-blocking boards, but the effect is very poor, because the number of drilled holes is too many, and the windward strength of the gypsum boards decreases; When it is not easy to pass through the front of the board, the gypsum board will be lifted, and the wind and sand will pass under the board, so the sand blocking effect is very poor
