Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] 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 .

[0020] The hinge point of the base 2 and the vertical rod 4 is 0.5 meters away from the ground 3 .

[0021] The wind-sand baffle 1 is 2 meters high, and the base 2 is 2 meters long and 2 meters wide.

[0022] 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 bein...

Abstract

The invention discloses a 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 rear end of the base is hinged with a pillar fixed on the foundation. The hinge joint between the base and the pillar is more than 10 meters above the ground. A flexible rope is connected between the pillar and the base. Due to a certain distance exists between the hinge joint of the base and the pillar and the ground, a stable triangular structure facing blown sand is formed to share wind force as well as a sufficient sand containing space is reserved below the base. As the blown sand easily converges on the hinge joint, the space is large enough to prevent a large deal of the blown sand from easily converging on the hinge joint so that the blown sand retaining plate can not be elevated rapidly. Meanwhile, the hinge joint is above the ground by a certain distance so that an elevation space of the blown sand retaining plate is sufficient.

Description

technical field [0001] The invention relates to a sand baffle, in particular to a novel self-elevating sand baffle. Background technique [0002] 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. The...
