Description

Construction structure for constructing sand-based high-vertical sand barrier by utilizing desert sand through triangular sand blocking net cage

Technical Field

The utility model relates to an engineering technical field that controls sand specifically is a high vertical sand barrier construction structures of sand bed is built to triangle-shaped blocks husky cylinder mould and utilizes desert sand.

Background

For more than ten years, the applicant observes the flowing condition of the desert under the action of wind power, and finds that a sand barrier which is not afraid of wind erosion is arranged at the top of a flowing sand dune, so that the flowing sand dune can be changed into a fixed sand blocking dam, and the theory is as follows: the sand barrier arranged on the top of a raised desert landform (a floating sand dune, a sand bank and a sand ridge) has a sand fixing function which is larger than that of the same sand barrier arranged on a flat desert, and the size of the sand fixing function is equal to 1.42 times of the height of the top of the desert landform, the square of the sum of the heights of the sand barriers on the top of the desert landform and the length of the sand barrier on a contour line of the top of the desert landform.

Calculating the formula: v =1.42 (H1 + H2) ² L

In the formula, V is the sand fixation amount, 1.42 is a constant, H1 is the height of the top of the raised desert landform, H2 is the height of the sand barrier at the top of the desert landform, L is the length of the sand barrier on the contour line of the top of the desert landform, and V is the minimum value of the sand fixation amount. "

The theory is proved to be in accordance with the natural law by the practice of sand blocking and fixing engineering by utilizing raised desert landforms (floating dunes, sand dikes and sand banks) for more than ten years. The method for constructing the high-rise sand barrier by using the desert sand to control the sand becomes a reality from a fantasy.

The mechanical sand barrier is used for intercepting and fixing desert quicksand, the sand-blocking and sand-fixing functions of the mechanical sand barrier are in direct proportion to the height of the sand barrier, the higher the vertical sand barrier is, the larger the function of intercepting the quicksand is, but the higher the sand barrier is, the higher the cost is, and the higher the sand barrier is, the more easily the sand barrier is damaged by storms.

The applicant proposes a theory of 'controlling sand by utilizing raised desert landforms', the raised desert landforms are used as the high-vertical sand barriers, the height of the raised desert landforms is brought into the height range of the high-vertical sand barriers, and a gate is opened for manufacturing the high-vertical sand barriers by utilizing local desert sand in desert. Therefore, the triangular sand blocking net cage for constructing the sand-based high-vertical sand barrier construction structure by using the desert sand is needed for desert control.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model and the technical task that provides overcome prior art's defect, provide a triangle-shaped blocks husky cylinder mould and utilizes desert sand to build high vertical sand barrier construction structures of sand bed.

The sand-based high-vertical sand barrier is a new name, and is characterized in that the sand-based high-vertical sand barrier is a high-vertical sand barrier constructed by using desert sand on site in a desert.

A triangle-shaped sand blocking cylinder mould which characterized in that: the triangular sand blocking net cage is a sand blocking net formed by combining a sand blocking net with the width of 60cm to 180cm and the porosity of 20 percent to 40 percent, a film which is attached to the middle part of the sand blocking net and used for preventing desert sand from leaking and supports which are fixed on two sides of the sand blocking net, wherein the width of the film is selected from 20cm to 50cm, the length of each support is one third of the width of the sand blocking net, the supports are vertical to the edges of the sand blocking net, and the interval between the supports is selected from 30cm to 150 cm.

A sand bank with a platform at the top is built on the desert by using the on-site desert sand according to a planned route, the height of the sand bank is selected from 30cm to 300cm according to requirements, and the width of the platform at the top of the sand bank is selected from 50cm to 300cm according to requirements.

Spreading a sand blocking net material rolled into a net roll along the center line of a platform at the top of a built sand bank, stacking and pressing desert sand with the thickness of more than 15cm on a film at the middle part of the sand blocking net material, then pulling up the edges at the two sides of the sand blocking net material, and drawing the edges inwards to enable the top ends of the brackets at the two sides to be contacted to form a triangular sand blocking net cage; and then piling desert sand on two sides of the triangular sand blocking net cage, vibrating the sand blocking net cage on one side to promote the desert sand to leak into the net cage, filling the sand blocking net cage, continuously piling the desert sand upwards until only the top of the sand blocking net cage is exposed, and building a wide sand ridge, wherein the top of the wide sand ridge is a platform with the width of 10cm to 30cm, and the wide sand ridge embedded with the triangular sand blocking net cage and a sand bank below the wide sand ridge form a sand-based high vertical type sand barrier.

The sand-based high-vertical sand barrier is completely composed of the desert sand from top to bottom and from inside to outside except the triangular sand blocking net cage embedded at the top, so that the manufacturing cost of the high-vertical sand barrier can be greatly reduced. The sand base high vertical sand barrier is formed by piling up a sand bank and a sand wide ridge to resist sand wind, the sand wide ridge is fixed by a triangular sand blocking net cage embedded in the middle and is protected by the sand wide ridge, the sand at the top of the windward side of the sand wide ridge can be stripped by the strong wind, the triangular sand blocking net cage is partially exposed, the exposed triangular sand blocking net cage can prevent the sand wide wind from stripping the sand wide ridge in the triangular sand blocking net cage and the sand wide ridge on the lee side, the strong wind can not damage the sand wide ridge, and the sand wide ridge can stably support the triangular sand blocking net cage and supplement each other, so that the sand base high vertical sand barrier can be kept complete for a long time.

The principle that the sand-based high vertical sand barrier intercepts quicksand is as follows: when the quicksand in the desert is carried by strong wind to the sand-based high vertical sand barrier and is blocked by the sand barrier, the strong wind changes from the horizontal direction to obliquely ascend from the sand bank to the top of the sand-based high vertical sand barrier, the top of the sand-based high vertical sand barrier cannot be pushed forward by the strong wind due to the blocking of the triangular sand blocking net cage, the quicksand carried by the strong wind obliquely rushes to the sky from the top of the sand-based high vertical sand barrier, the quicksand falls on a lee slope of the sand-based high vertical sand barrier due to gravity, the strong wind blows away the sky, a breeze turbulent flow area is formed on the lee side of the sand-based high vertical sand barrier, and the sand falling on the lee slope can not be driven by the wind force and is deposited on the lee slope.
