Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Such as figure 1 As shown, a self-elevating sand baffle includes a wind and sand baffle 1 and a base 2, the front end of the base 2 is connected to the wind and sand baffle 1, and the base 2 and the wind and sand baffle 1 form an "L" shape. A support 6 is provided below the front end of the base 2; it also includes a vertical bar 4, which is located at the front end of the base 2, the lower end of the vertical bar 4 is fixed on the ground 3, and the upper end protrudes upwards, and the upper end is connected by a chain 5 to the front of base 2.
[0024] The wind-sand baffle 1 is 2 meters high, and the base 2 is 2 meters long.
[0025] The bracket 6 is two vertical rods, which are installed on both sides of the front end of the base 2 respectively.
[0026] The height of the support 6 is 0.2 meters.
[0027] The distance between the upper end ...

The invention discloses a novel self-elevation sand retaining plate which comprises a blown sand retaining plate and a base. The front end of the base is connected with the blown sand retaining plate. The base and the blown sand retaining plate form an L shaped. A support frame is arranged below the front end of the base. The novel self-elevation sand retaining plate further comprises a pillar which is arranged at the front end of the base. The lower end of the pillar is fixed on the ground and the upper end of the pillar stretches out upwards and is connected on the front end of the base or the lower end of the blown sand retaining plate through a flexible rope or a chain. The support frame is arranged below the front end in a connected mode so that a certain space is reserved below the base and partial blown sand can fill in and the function of self elevation can be achieved. The upper end of the pillar is above the ground by a certain distance so that the flexible rope or the chain pulls the blown sand retaining plate upwards in order to prevent the retaining plate from being turned over by blowing and prevent horizontal acting force of pull force which affects elevation of the retaining plate. Meanwhile, the height of the pillar above the ground and the length of the rope or the chain can ensure a sufficient elevation space for the retaining plate. The novel self-elevation sand retaining plate is novel in structure, and strong in practicality.
Description
[0001] technical field [0002] The invention relates to a sand baffle, in particular to a novel self-elevating sand baffle. Background technique [0003] The climate in northwestern China is dry, rainfall is scarce, and sandstorms are frequent. In recent years, with the advancement of my country’s western development, the infrastructure construction in Northwest China has developed rapidly. Engineering construction in urban construction and other fields has become an important issue affecting the quality of engineering construction in these fields, which has restricted the development of economic construction in the western region to a certain extent. Mechanical sand-retaining fence is a kind of engineering sand-prevention measure, and it is an important technical means to prevent and control railway or highway sand damage. Common engineering sand-prevention measures include concrete sleeper sand-retaining wall, PE mesh high vertical sand barrier, reed sand-retaining fence, ...
