Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model discloses synthesize and fix husky structure, including a plurality of solid sand-protecting barriers group that set up side by side, every solid sand-protecting barriers group comprises the solid sand-protecting barriers 1 that a plurality of the same quantity set up side by side, and the solid sand-protecting barriers 1 dislocation set in two adjacent solid sand-protecting barriers group.

The distance between adjacent sand fixing barrier groups is 5-10 meters; the distance between adjacent sand-fixing barriers 1 in the same sand-fixing barrier group is 5-10 m.

As shown in figure 2, the sand-fixing barrier 1 in the comprehensive sand-fixing structure of the utility model comprises a front sand-fixing layer 2, a latticed sand-fixing layer 4 and a vegetation protection layer 6 which are fixedly connected in sequence,

the front-end sand fixing layer 2 comprises an outer frame, the outer frame is an isosceles triangular prism, a latticed framework is arranged in the outer frame, and a grid in the framework is a first square 3;

the latticed sand fixing layer 4 consists of a quadrangular frame and a plurality of isolation plates, the isolation plates and the frame enclose a plurality of second grids 5, and all the second grids 5 are arranged into at least two rows; the length of the frame is equal to the length of the bottom edge on the bottom surface in the front sand fixing layer 2.

The vegetation protection layer 6 is composed of a quadrangular prism-shaped frame and a plurality of partition plates, the partition plates and the frame enclose a plurality of third grids 7, all the third grids 7 are arranged into at least three rows, and the length of the frame is the same as that of the frame.

The bottom surface of the front sand fixing layer 2 is fixedly connected with one side wall of the frame in the latticed sand fixing layer 4, and the side wall opposite to the side wall fixedly connected with the bottom surface of the front sand fixing layer 2 in the latticed sand fixing layer 4 is fixedly connected with one side wall in the vegetation protection layer 6.

The sizes of the second square 5 and the third square 7 can be set to be 0.5m multiplied by 0.5m to 1.5m multiplied by 1.5m according to the local wind sand condition, and the height can be set to be 30 cm to 60 cm.

The length of the first square grid 3 is the same as that of the second square grid 5, the width of the first square grid 3 is half of that of the second square grid 5, the height of the first square grid 3 is half of that of the second square grid 5, and the size of the second square grid 5 is the same as that of the third square grid 7. The size that sets up three kinds of squares like this makes front end sand stabilization layer 2 can keep out great wind, helps sand prevention vegetation to grow.

The front sand fixing layer 2, the latticed sand fixing layer 4 and the vegetation protection layer 6 are all made of environment-friendly materials such as reed rods, stones and the like which can be utilized locally.

Use the utility model discloses during the structure of fixing sand is synthesized: a plurality of sand fixing barriers 1 are arranged in a sand fixing front edge section side by side, the vertex of a middle waist triangle vertex angle in a front end sand fixing layer 2 faces the local main wind direction to form a first row of sand fixing barrier group, then a plurality of rows of sand fixing barrier groups consisting of the sand fixing barriers 1 are sequentially arranged along the direction of the main wind direction, the sand fixing barriers 1 in two adjacent rows of sand fixing barrier groups are arranged in a staggered mode, and therefore the adjacent sand fixing barriers 1 form a quincunx shape, and the figure is 1. After the sand fixation structure is set, local or introduced sand control vegetation 8 is planted in the third square 7.

The direction of the front sand fixing layer 2 is consistent with the local main wind direction, which is beneficial to dispersing wind pressure and improving the durability and stability of the structure. The front end sand fixing layer 2 is positioned in a sand fixing fore-speaking section, so that the height of the front end sand fixing layer 2 is lower than that of the grid-shaped sand fixing layer 4 and the vegetation protection layer 6 in design, the durability and the stability of the structure are improved, the wind speed near the earth surface can be effectively reduced, and the cross-country wind and sand flow structure can be disturbed.

The latticed sand fixing layer 4 mainly has the functions of fixing the surface sand storm and purifying the ambient sand storm flow, so that most of the sand storm close to the surface is intercepted, and the wind speed is effectively reduced. Providing advantages for plant growth in the vegetation protection layer 6.

The third square 7 in the vegetation protection layer 6 is mainly used for planting local drought-resistant and cold-resistant local vegetation or introduced plants. The planted plants mainly use shrubs as main materials and are assisted by perennial herbaceous plants, and species matching of the shrubs and the grass is beneficial to forming a multi-level ecological protection system in the later period. Because the square sand barriers have a certain service life, in the later period of use, along with the damage of the structure or the burying by wind sand, the ecological protection system in the vegetation protection layer 6 gradually replaces the function of fixing the sand barriers, thereby playing the roles of wind prevention and sand fixation.

The sand fixing barriers 1 formed by the front-end sand fixing layer 2, the latticed sand fixing layer 4 and the vegetation protective layer 6 which are fixedly connected in sequence are of wild goose-shaped structures, all the sand fixing barriers 1 are arranged in a quincuncial pile shape, and a space is reserved between every two adjacent sand fixing barriers 1 to form a sand dredging channel. The sand dredging channel can reduce the possibility of accumulation of the cross-border sand in front of the barrier, so that the sand accumulated in front of the barrier is dispersed to a rear area through the sand dredging channel, the time of burying the sand fixing barrier by the sand is effectively reduced, and the service life is prolonged; and manual sand cleaning operation can be carried out through the sand dredging channel, so that the service time of the sand stabilizing barrier is prolonged.

The utility model discloses gu husky structure has solved the consumptive material that exists in the current measure of stabilizing sand and hindering sand many, work load is big, the life-span is short, the single scheduling problem of protection mode.
