Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, a self-elevating sand baffle includes a wind-sand baffle 1 and a base 2, the front end of the base 2 is connected to the wind-sand baffle 1, and the rear end is hinged to a vertical rod 4 fixed on the foundation. A chain 5 is also connected between the bar 4 and the base 2 , and the two ends of the chain 5 are connected to the middle part of the vertical bar 4 and the base 2 .

[0016] The wind-sand baffle 1 is 2 meters high, and the base 2 is 2 meters long and 2 meters wide.

[0017] Adopt the baffle plate of the present invention to be arranged into a sand-retaining fence, such as figure 2 As shown, when the wind and sand are relatively large, the chain 5 can effectively prevent the wind and sand baffle 1 from being blown over by the wind.

[0018] Although the specific implementation of the present invention has ...

Abstract

The invention discloses a self-lifting sand board, which includes a sandy wind baffle and a base, wherein the front end of the base is connected with the sandy wind baffle; the rear end of the base is hinged with a vertical rod fixed on a foundation; and a flexible rope is connected between the vertical rod and the base. As the front end of the base is not in permanent connection with the ground and the rear end of the base is hinged with the vertical rod, in case of sandy wind, the sandy wind baffle is lifted, a clearance is reserved under the base, and windy sand partially deposits in the clearance, so that the sandy wind baffle is lifted gradually, and is prevented from being buried by the windy sand; meanwhile, the base is connected with the vertical rod fixed on the foundation, so as to be prevented from being blown away by heavy sandy wind; besides, the base is connected with the vertical rod through the flexible rope with proper length guaranteeing the lifting space of the sandy wind baffle and preventing the sandy wind baffle from being blown down by the sandy wind.

Description

[0001] technical field [0002] The invention relates to a sand baffle, in particular to a 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, etc. ...
