Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like figure 1 As shown, a self-elevating sand baffle includes a sand baffle 1 and a base 2, the front end of the base 2 is connected with the sand baffle 1, and the rear end is hinged with a vertical rod 4 fixed on the foundation, and the vertical A chain 5 is also connected between the rod 4 and the base 2 , and both ends of the chain 5 are connected to the middle of the vertical rod 4 and the base 2 .

[0021] The hinge point of the base 2 and the vertical rod 4 is 0.5 meters away from the ground 3 .

[0022] The sand baffle 1 is 2 meters high, and the base 2 is 2 meters long and 2 meters wide.

[0023] The baffles of the present invention are arranged to form a sand barrier, such as figure 2 As shown, when the sandstorm is relatively large, the chain 5 can effectively prevent the sandstorm baffle 1 from being blown over by the wind.

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

[0001] technical field [0002] The invention relates to a sand baffle, in particular to a novel self-elevating sand baffle. Background technique [0003] In the northwestern part of my country, the climate is arid, the rainfall is sparse, and the sandstorm activities are frequent. In recent years, with the advancement of the development of the western region of my country, the infrastructure construction in the northwest region has developed rapidly, but the prevention and control of sandstorm disasters still plagues railways, highways, and protection of ancient sites. Engineering construction in urban construction and other fields has become an important issue affecting the quality of engineering construction in these fields, and has restricted the development of economic construction in the western region to a certain extent. Mechanical sand barrier is an engineering sand control measure and an important technical means to prevent sand damage on railways or highways. Commo...
