One-way sand-guide sand control device and application

Abstract

The invention provides a one-way sand-guide sand control device. The one-way sand-guide sand control device comprises a plurality of groups of sand barriers which are arranged side by side in multiple rows, a gap is formed between every two rows of combined sand barriers, each sand barrier is composed of a plurality of one-way sand-guide devices which are arranged side by side, one side of each one-way sand-guide device is a sand dredging face with an arc face, and the tail of the other side of each one-way sand-guide device is a sand blocking face. After the structure is adopted, the one-way sand-guide sand control device has the following advantages that through the method of combining sand dredging through the arc dredging face at the front end and sand blocking through the sand blocking face at the tail, sand flow with the main wind direction is dredged, sand grains are blocked in the process of damage of the sand flow in the secondary wind direction, the degree of road sand damage can be effectively reduced, sand damage can be effectively prevented and controlled, and the problems that an existing protection system can generate sand accumulation bodies in a sand damage area mainly in the single wind direction, then the sand accumulation bodies can generate secondary sand damage to a linear project and long-term protection on the project cannot be met are solved; the effects of sand blocking in the secondary wind direction and sand conveying in the main wind direction are achieved, and the problems that an existing road protection system is single in method and inflexible are solved; and the one-way sand-guide sand control device is simple in structure and low in maintenance cost.

Description

technical field [0001] The invention relates to the technical field of sand control, in particular to a one-way sand control device and its application. Background technique [0002] The roads and railways in the desert and Gobi areas have played an important role in promoting the economic development of desert areas with underdeveloped transportation. However, there are many windy sands in desert areas, and when the windy sand flow encounters the road matrix, it is easy to accumulate in the area where the wind speed decreases, causing the road to be buried by sand, seriously affecting the safety of road use, causing traffic accidents, and endangering personal safety. [0003] Aeolian sand is very harmful to roads. A large amount of quicksand not only affects road construction, but also greatly affects traffic and increases the incidence of traffic accidents. If the road area is reduced, the sandy section of the road will easily cause vehicle rollover accidents and affect d...

However, there are many windy sands in desert areas, and when the windy sand flow encounters the road matrix, it is easy to accumulate in the area where the wind speed decreases, causing the road to be buried by sand, seriously affecting the safety of road use, causing traffic accidents, and endangering personal safety

[0003] Aeolian sand is very harmful to roads. A large amount of quicksand not only affects road construction, but also greatly affects traffic and increases the incidence of traffic accidents. If the road area is sandy, it is easy to cause vehicle rollover accidents and affect driving safety; when the road area is seriously sandy, vehicles cannot pass through, and stranded vehicles form a sand-blocking belt, causing secondary sand accumulation on the road surface, and traffic interruption in severe cases

At present, the existing road sand prevention methods in our country mainly include grass squares, gravel sand pressing and sand control nets, which have good effects on preventing dust and further spread of desertification, but cannot play a long-term protective effect on roads along the road.

In the event of sand and dust buried, only mechanical or manual cleaning can be used

However, due to the long line, a lot of manpower and material resources will be used, the cleaning cost is high, and the maintenance cost is high, so it is difficult to solve the problem fundamentally
