[0002] At present, with the rapid development of economic construction in western my country, urban infrastructure construction such as railways and highways has been widely carried out in the desert and Gobi areas in northwest my country, where vegetation is sparse and there is a lot of wind and sand. Since the opening of Lanzhou-Xinjiang Railway and Qinghai-Tibet Railway, wind and sand disasters have become a major hidden danger to the safe operation of trains. The suspension of trains due to the burial of railways by wind and sand has caused huge economic losses to people's travel and railway transportation.

[0003] The existing engineering sand control measures mainly include sand fixation and sand blocking, and sand blocking measures are more commonly used. Commonly used sand blocking measures include concrete sleeper sand retaining walls, PE net high vertical sand barriers, reed sand retaining fences, etc. These engineering sand control measures have played a certain role in the prevention and control of wind and sand disasters in existing railways, highways, etc.

The limiting strip is fixedly connected to the sliding sleeve, and the limiting groove is provided on the inner wall of the fixed sleeve. The limiting strip is inserted into the limiting groove, and the limiting strip is slidably connected to the limiting groove.

[0010] Furthermore, a cleaning brush is provided between the fixed sleeve and the sliding sleeve. The cleaning brush is fixedly connected to the fixed sleeve. The cleaning brush is used to clean sand and dust on the outer wall of the sliding sleeve to prevent sand and dust from entering the telescopic sleeve.

The limiter is used to limit the rotation direction of the impeller. At the same time, the impellers on adjacent cross bars rotate in opposite directions, making the turbulence generated by the impeller more chaotic, further reducing the wind speed of the wind and sand, achieving good sand blocking performance. At the same time, the turbulence is used to turbulently slow down the wind and sand in advance, reducing the wind speed when the wind and sand contact the sand retaining wall, thereby increasing the service life of the sand retaining wall; 2. By setting up a telescopic sleeve, the normal use of various components in the limiter is protected, and the components are prevented from not being able to operate normally due to the invasion of wind and sand, which further increases the service life of the sand retaining wall; 3. By setting up the installation components, the installation components can be used for rapid assembly during on-site construction, thereby achieving the effect of rapid assembly of the sand retaining wall at the construction site.

[0024] The implementation principle of the name of the embodiment of the present application is as follows: when using the sand retaining wall, first insert one end of the mounting rod 10 into the ground, then move the column 1 to be fixedly connected with the mounting rod 10, then move the cross bar 2 to between the two columns 1, then move the cross bar 2 to drive the first clamping groove to engage with the second clamping groove, and then pass the locking bolt 92 through the side wall of the first clamping groove and threadedly connect with the column 1, then fix the cross bar 2 to the column 1, install several cross bars 2 in sequence, and then install the impeller 3 on the cross bar 2, the rotating shaft 4 of the impeller 3 passes through the cross bar 2 and is fixedly connected with the fixed ratchet 51 of the limiter 5, and then fix one end of the pull rope 203 to the top of the column 1, and the other end is fixedly connected to the connecting ring 202 of the stabilizing block 201, place the stabilizing block 201 on both sides of the column 1, and pull the two sides of the column 1 sideways to achieve the stability of the column 1 when blown by wind and sand.

[0025] When wind passes through the impeller 3, the wind drives the impeller 3 to rotate, the rotation of the impeller 3 drives the rotating shaft 4 to rotate, the rotation of the rotating shaft 4 drives the fixed ratchet 51 to rotate, the fixed ratchet 51 drives the sliding ratchet 52 to slide along the rotating shaft 4 when rotating, the sliding ratchet 52 drives the elastic member 53 to deform, so that the fixed ratchet 51 can rotate, and at the same time the sliding ratchet 52 drives the sliding sleeve 62 to slide in the fixed sleeve 61, the sliding sleeve 62 drives the limiting strip 71 to slide in the limiting groove 72, and the sliding ratchet 52 is cleaned by the cleaning brush 8. The wind and sand on the surface of the moving sleeve 62; the airflow disturbance generated by the rotation of the impeller 3 reduces the speed of the wind and sand, and reduces the ability of the wind and sand to carry sand and dust. The limiter 5 is used to limit the rotation direction of the impeller 3. At the same time, the impellers 3 on the adjacent cross bars 2 rotate in opposite directions, making the turbulence generated by the impeller 3 more chaotic, further reducing the wind speed of the wind and sand, achieving good sand blocking performance, and at the same time using the turbulence to pre-disturb and slow down the wind and sand, reducing the wind speed when the wind and sand contact the sand retaining wall, thereby increasing the service life of the sand retaining wall.
