DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0026] Generally, the wind sand speed at 1 meter is relatively low, because the area close to the ground is affected by the ground friction, and the wind flowing close to the ground will be affected by more resistance, so that the wind sand speed is slowed down, the wind sand speed at 3 meters is often faster, with the increase of height, the influence of ground friction is gradually weakened, the resistance of wind flow is reduced, so that the wind sand can move faster, can carry more sand particles, the wind sand at 2 meters is less affected by ground friction, the speed is relatively fast, but compared with 3 meters, it is also affected by a certain degree of ground interference, the speed is slightly slower, the wind sand at this height is moderate, which has certain kinetic energy, and is not as high as 3 meters.

[0027] As shown in Figure 1 The present application provides a technical solution: a multifunctional segmented combined sand retaining wall system, comprising two support piles 1, a lower sand retaining structure 2, a middle sand retaining structure 3 and an upper sand retaining structure 4, wherein the middle sand retaining structure 3 and the lower sand retaining structure 2 are installed between the two sides of the two support piles 1, and the middle sand retaining structure 3 is installed above the lower sand retaining structure 2, and the upper sand retaining structure 4 is installed at the top of the support pile 1, the lower sand retaining structure 2, the middle sand retaining structure 3 and the upper sand retaining structure 4 form a three-section sand prevention structure, the bottom of the support pile 1 is an earth anchor 7, which is convenient for fixing, generally, in the height of 1-3 meters, the sand particles carried by high altitude are more and the wind speed is faster, the sand particles carried by low altitude are less and the wind speed is slower, the three-section sand prevention structure differentiates the wind sand conditions of different heights in the same area, and better sand retaining effect is realized.

[0028] As shown in Figure 2As shown, the upper sand blocking structure 4 includes a plate frame 401, both ends of the top of the plate frame 401 are fixed with side plates 404, a rotating rod is rotatably installed between the side plates 404, the surface of the rotating rod is fixedly wound with a sand blocking net 406, a rotating shaft rod 408 is rotatably installed between the two side plates 404 close to the plate frame 401, the surface of the rotating shaft rod 408 is fixedly provided with a sand flowing plate 411, the edge of the sand blocking net 406 is connected with the edge of the side of the sand flowing plate 411 away from the rotating shaft rod 408, both ends of the rotating shaft rod 408 are further fixedly provided with diaphragm sheets 407, and the diaphragm sheets 407 are further connected with the sand flowing plate 411. After the sand blocking net 406 is opened, the diaphragm sheets 407 at both ends can reduce the situation that the wind sand flows out from the cavity between the sand blocking net 406 and the support pile 1. Through the arrangement of the above structure, the sand blocking net 406 can be wound on the surface of the rotating rod and opened during use. When sand blocking is performed, the sand blocking net 406 is opened and connected with the sand flowing plate 411. The sand flowing plate 411 is a plastic plate or an acrylic plate to reduce friction. After the sand blocking net 406 completes the sand blocking action, the sand particles flow down from the sand flowing plate 411. The top of the plate frame 401 is provided with a cavity groove 402. The cavity groove 402 can contain sand particles. The sand particles flowing down from the sand flowing plate 411 enter the cavity groove 402 under the action of gravity. Both ends of the bottom of the plate frame 401 are fixedly provided with support through pipes 5. The ends of the support through pipes 5 are connected through sand burying barrels 6. The sand particles falling into the cavity groove 402 enter the sand burying barrels 6 through the support through pipes 5.

[0029] As Figure 2 and Figure 3 shown, it is necessary to know that the sand blocking wall system is installed with the support pile 1 being inclined to be inserted into the sand at an inclination of 15°-30°. The side plates 404 are fixed in a vertical state on the top of the plate frame 401. The bottom inner wall of the cavity groove 402 at the plate frame 401 is also inclinedly arranged, and the bottom inner wall of the cavity groove 402 is further provided with a protruding portion 403. The protruding portion 403 is inclined from the middle of the cavity groove 402 to the two ends close to the side plates 404. Therefore, in this case, when the sand particles flow into the cavity groove 402, they automatically flow to the two ends and enter the sand burying barrels 6 through the support through pipes 5. In the implementation process, the sand burying barrels 6 will increase in weight due to the increase of the sand particles, and because they are buried in the sand, the sand burying barrels 6 are in full contact with the sand. After increasing the self-weight, the sand burying barrels 6 provide sufficient stability for the support pile 1.

[0030] One of the side plates 404 is rotatably installed with a crank 409. The crank 409 is coaxially fixed with the rotating rod for winding the sand blocking net 406. The crank 409 is screwed with a fixed bolt 410 for fixing the crank 409. In the implementation process, both sides of the top of the support pile 1 are provided with insertion grooves 102. Both ends of the bottom of the plate frame 401 are fixedly provided with insertion blocks 405. The installation of the upper sand blocking structure 4 is realized by inserting the insertion blocks 405 into the insertion grooves 102.

[0031] AsFigure 4 As shown, the middle sand blocking structure 3 comprises a peripheral frame 301 and a plurality of interval frames 302, each interval frame 302 is in the shape of a flat "mouth", the interval between each two interval frames 302 is 1-5 cm, and each interval frame 302 is slidingly connected with each other, the inner side of each interval frame 302 is fixed with a limiting block 303, one side of the limiting block 303 is provided with a notch, the outer side of the adjacent interval frame 302 is fixed with a protrusion 305 at the corresponding position, the protrusion 305 is slidingly arranged at the notch, and a spring 304 is arranged between the protrusion 305 and one end of the notch, under the action of no external force, each interval frame 302 can be translated under the pushing of the spring 304, and in the actual installation process, the interval frame 302 is translated and pushed out under the action of the spring 304 to form a stepped net surface structure, and the stepped net surface structure faces the side blown by the wind.

[0032] The stepped net surface structure can weaken the wind sand to a certain extent, because the stepped net surface structure is in the shape of a whole cone, after the wind sand impacts on the stepped net surface structure, it will be dispersed to all directions, the impact effect of the wind sand is weakened, the kinetic energy of the wind sand is dispersed and consumed, so as to reduce the wind speed and weaken the carrying sand ability of the wind sand, and when the wind sand impacts on the stepped net surface structure, the interval frame 302 will repeatedly shake under the effect of the spring 304, which further increases the turbulence effect and reduces the possibility of sand particles being stuck in the gap.

[0033] As shown in the figure, Figure 4 The lower sand blocking structure 2 comprises a sand prevention net 201, the top of the sand prevention net 201 is fixed with a top plate 204, the peripheral frame 301 is fixedly installed on the top of the top plate 204, the side of each support pile 1 facing the sand prevention net 201 is provided with a rail groove 101, the two ends of the sand prevention net 201 close to the support pile 1 are provided with a side plate 202, the side plate 202 and the sand prevention net 201 are connected through a connecting wire net 203, the connecting wire net 203 is made of iron or rubber and has elastic effect, and the side plate 202 is slidingly arranged in the rail groove 101 of the support pile 1.

[0034] It should be noted that the length of the rail groove 101 is at least twice the width of the two ends of the sand prevention net 201, the width of the upper half of the rail groove 101 is matched with the side plate 202, the side plate 202 is inserted into the rail groove 101 from the upper half of the rail groove 101 and moves downward, through the arrangement of the structure, the blocking effect of the wind sand is achieved, the elastic connecting wire net 203 on both sides can make the sand prevention net 201 repeatedly shake, so as to also achieve good turbulence effect, reduce the wind sand speed, and weaken the carrying sand effect of the wind sand.

[0035] In summary, the multifunctional segmented combined sand retaining wall system provided by the embodiment has a significant sand retaining effect. The system is composed of a support pile 1, a lower sand retaining structure 2, a middle sand retaining structure 3 and an upper sand retaining structure 4 to form a three-section sand preventing structure, and differentiates the treatment according to the wind sand conditions of different heights in the same area. In the upper sand retaining structure 4, the sand retaining net 406 can be wound on the surface of the rotating rod, and is connected with the sand flow plate 411 when in use, and the sand particles flow down from the sand flow plate 411 after the sand retaining action is completed, enter the sand burying barrel 6 through the cavity groove 402 and the support through pipe 5, and increase the weight to provide stability for the support pile 1. The stepped net surface structure of the middle sand retaining structure 3 can be translated and pushed out under the action of the spring 304, is in the shape of a cone and faces one side of the wind direction, can weaken the wind sand, makes the wind sand impact and disperse in all directions, reduces the wind speed and weakens the sand carrying capacity, at the same time, the interval frame 302 repeatedly shakes under the action of the spring 304, increases the effect of disturbing flow and reduces the possibility of sand particles being stuck in the gap, and the sand preventing net 201 of the lower sand retaining structure 2 is installed in the rail groove 101 of the support pile 1 through the sliding of the side plate 202, the elastic connecting wire net 203 on both sides makes the sand preventing net 201 repeatedly shake, has a good effect of disturbing flow, reduces the wind sand speed and weakens the sand carrying effect, and overall, the sand retaining wall system effectively realizes the blocking and weakening of the wind sand through the synergistic effect of the structures.
