Description
Technical Field
The invention relates to the field of wind-blown sand prevention and control, in particular to a sand accumulation lateral movement protection device and a sand prevention system for sand prevention engineering.
Background
The measures of the wind and sand protection project can be divided into measures of blocking sand, fixing sand, transporting sand and guiding sand according to functions, wherein the measure of blocking sand is one of the most important measures in the whole wind and sand protection project. The sand-blocking measures can be divided into a plurality of measures according to different functions, purposes and industries, such as: sand blocking walls, sand blocking nets and the like. The principle of the sand-blocking measure is based on the principle of blocking sand substances, and the sand-blocking measure is mainly used for blocking wind and sand flow and enabling the sand substances to be accumulated nearby the sand-blocking measure, so that the aim of reducing the amount of sand in the downwind direction of the sand-blocking measure is fulfilled. In order to achieve the maximum sand-blocking effect, the engineering sand-blocking measure is arranged to move perpendicular to the main wind direction, namely: the included angle is 90 degrees. The sand-blocking function of the sand-blocking measure is obvious in the early stage, but the sand-blocking function is gradually reduced along with the increase of the amount of sand accumulated nearby. Especially under the condition of non-main wind direction, when the included angle between the wind direction and the sand-blocking measure is less than 90 degrees, the influence of wind on the accumulated sand is the largest, so that the wind easily moves along the direction of the sand-blocking measure, namely moves laterally, and especially the smaller the included angle between the wind direction and the sand-blocking measure is, the larger the lateral movement capability of the wind-blocking measure is. Once the sand accumulation of the sand blocking fence moves laterally, the sand blocking fence becomes a new sand source, and the sand blocking fence is easy to climb over the sand blocking measures, so that the sand blocking effect of the sand blocking measures is weakened.
The existing sand-blocking engineering sand accumulation has the following problems: the lateral movement of the accumulated sand in the sand blocking project causes the sand blocking benefit of the sand blocking project to be rapidly reduced, and the sand blocking function of the sand blocking project is influenced; the lateral movement of the accumulated sand in the sand blocking project is easy to cause the sand substances to cross the sand blocking project, thereby causing the harm increase of a protective area in the downwind direction; the sand accumulation of the sand blocking project is caused by the lateral movement of the sand accumulation to become a new sand source, and the sand substances are easy to move for a long distance along the sand blocking project and even move back and forth to cause secondary sand damage, so that the sand damage area is enlarged, and the damage to a wind and sand protection system is great.

In this embodiment, the fifth sand-blocking project 17 and the sixth sand-blocking project 18 form an included angle of 45 degrees with the main wind direction, and the third protection piece 43 and the fourth protection piece 44 are also set to form an included angle of 45 degrees, so that the main wind direction is 90 degrees with the third protection piece 43 and the fourth protection piece 44, which not only can effectively prevent the accumulated sand from moving laterally, but also has a sand guiding function, so that the wind sand flow is far away from the fifth sand-blocking project 17 and the sixth sand-blocking project 18, and the function of protecting the sand-blocking projects and the project areas is achieved.
Further, the protection area 12 is not provided with a protection member because the seventh sand blocking project 19 and the eighth sand blocking project 20 are on the leeward side.
Any of the sand control projects in combination with any of the guards provided in the embodiments above form a sand control system. The sand blocking system has better sand blocking efficiency, and can increase the sand blocking amount and the sand blocking control range; the sand blocking system can also effectively prevent the sand accumulation of the sand blocking engineering from moving laterally; along with the development of the accumulated sand, the sand blocking system can effectively form a high and stable sand blocking body, and the sand blocking body has good sand prevention and guiding effects.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
