Technical Field
The utility model belongs to the technical field of engineering sand prevention, a water-passing sand-blocking sand barrier is related to.
Background
With the rapid development of economic construction in western regions of China, the construction of basic facilities such as railways, highways, urban development and the like is widely spread in northwest deserts and gobi regions of China. And the sand storm has serious harm to railways and highways, and if necessary protective measures are not taken, the sand storm can cause serious damage to infrastructures such as railways and highways, and even threaten the safe operation of the infrastructures.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the utility model discloses cross water and hinder husky barrier, including a plurality of monomer sand barriers 1, these a plurality of monomer sand barriers 1 are the wave fold line shape setting, the junction of adjacent monomer sand barriers 1 and the one end rigid coupling of earth anchor 3, the other end and the 9 rigid couplings in ground of earth anchor 3.
As shown in fig. 2 and 3, the utility model discloses water hinders monomer sand barrier 1 in sand barrier, support frame 5 including vertical setting, support frame 5 is by setting gradually first arc corner 10, the straight section 12 of plane shape and the 11 rigid couplings of second arc corner form, one side of straight section 12 and one side rigid coupling of first arc corner 10, the opposite side of first arc corner 10 is the free side, the opposite side of straight section 12 and one side rigid coupling of second arc corner 11, the opposite side of second arc corner 11 is the free side, the free side of first arc corner 10 and the free side of second arc corner 11 are located the both sides of straight section 12 place vertical plane respectively, two stands of support frame 5 are located the both sides of straight section 12 place vertical plane respectively promptly. The lower ends of two upright posts of the support frame 5 extend into the ground 9 and are fixedly connected with two concrete foundations 8 poured under the ground 9 respectively, the frame 5 is sequentially provided with a sand blocking layer 4 and a sand dredging layer 6 from top to bottom, no gap exists between the sand blocking layer 4 and the sand dredging layer 6, a gap exists between the sand dredging layer 6 and the ground 9, and the gap is an empty layer 7.
The sand-blocking layer 4 is formed by installing a metal plastic-coated net with low porosity (the porosity is about 30%) on the support frame 5, and can also be adjusted according to the structure of sand flow. The height of the sand blocking layer 4 is about 1-1.5 m, and can be adjusted according to actual conditions. The function of the sand blocking layer 4 is mainly to intercept the wind and sand flow passing through the environment and block most of the sand particles near the sand barrier.
The sand dredging layer 6 is formed by installing a metal plastic coated net with the porosity of more than 50% on the support frame 5, the sand dredging layer 6 is positioned below the sand blocking layer 4, and the height of the sand dredging layer 6 is about 10-15 cm. The large porosity of the dredging layer 6 is mainly used for weakening the destructive effect of silt carried by flood on sand barriers, and most of silt can pass through the sand barriers when the flood passes through the border.
The height of the vacant layer 7 is 5-10 cm above the ground, and the height can be adjusted according to actual conditions. The vacant layer 7 is mainly used for preventing the direct impact of particles with large particle diameters on the sand barrier and avoiding the sand barrier from being damaged, and when the flood crosses the border, the sand particles deposited nearby the sand barrier can be moved to the downwind direction along with the flood, so that the sand barrier can keep an efficient sand prevention function, the maintenance cost of the sand barrier is reduced, and the service life is prolonged.
The support frame 5 is made of stainless steel pipes. The bottom of the support frame 5 is reinforced by a concrete foundation 6, so that the stability of the sand barrier can be enhanced.
When the water-passing sand-blocking barrier of the utility model is used, a plurality of monomer sand-blocking barriers 1 are installed according to the structural form shown in figure 1. During the installation, in two adjacent monomer sand barriers 1, the first arc corner 10 of a monomer sand barrier 1 contacts with the second arc corner 11 of another monomer sand barrier 1, and these two corners that contact are connected through an earth anchor 3 to with the ground 9 rigid coupling, earth anchor 3 is towards windward side and rivers direction one side, in order to strengthen the stability of sand barrier, prevents the destruction that sand storm flow and flood caused sand barrier, prolongs the life of sand barrier. After the installation is finished, all the single sand barriers 1 form the wave-fold-shaped water passing sand-blocking sand barrier. When the sand storm crosses the border, because the height of hindering husky layer 4 is greater than the height of hydrophobic layer 6 far away, and the height of dredging husky layer 6 is only 10 ~ 15cm, jump sand grain can bump into hindering husky layer 4, plays the effect of hindering the sand. During the flood crosses the border, silt that carries in the flood can pass through sand barrier through dredging sand bed 6 and vacant layer 7, and the large particle size object of wrapping up in the flood such as stone, directly passes through vacant layer 7, through sand barrier, has avoided the direct impact to sand barrier to when the flood crossed the border, the flood can be with near sedimentary sand grain of sand barrier transport to the downwind direction.
The utility model provides a 1 wave fold line of monomer sand barrier lays, mainly is in order to prevent the sand and wind stream of many wind directions and weaken the impact of flood crossing to the sand barrier. However, when the flood crosses the border, the impact force on the connecting section between the adjacent single sand barriers 1 is large, so that the adjacent single sand barriers 1 are connected through the arc-shaped corners 2, the damage of the flood to the water-passing sand-blocking sand barrier is weakened and dispersed, meanwhile, the damage of wind and sand flow to the sand barrier is weakened, and the effect of prolonging the service life of the sand barrier is also achieved.
