Problems solved by technology

These engineering sand control measures have played a certain role in the prevention and control of wind and sand disasters such as railways and highways, but there are generally problems such as difficult construction, high cost, and low sand control benefits.
Especially when sand control is carried out in windy areas with severe sand damage from multiple wind directions, the existing sand control measures have problems such as low sand control benefits and high maintenance costs.

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 and figure 2 As shown, the sand-resistance and sand-fixing cage of the present invention is hollow, and the horizontal plane projection is two connected trapezoids, and the two trapezoids share a shorter bottom.

[0014] The sand-blocking and sand-fixing cage includes a first support 1 , a second support 2 and a third support 3 which have the same shape and are arranged in sequence.

[0015] The shape of the first support 1, the second support 2 and the third support 3 can be image 3 shown in the arc shape, it can also be Figure 4 The shown door frame shape can also be other arbitrary shapes.

[0016] The size of the first bracket 1 and the size of the third bracket 3 are greater than the size of the second bracket 2, and the distance between the first bracket 1 and the second bracket 2 and the distance ...

Abstract

The invention discloses a portable sand-blocking and stabilizing cage which is hollow. The horizontal plane projection of the sand-blocking and stabilizing cage is two connected trapezoids, and the two trapezoids share a bottom with a smaller size. The sand-blocking and stabilizing cage simultaneously has stabilizing and sand-blocking functions, is used in valley areas or windy and sandy areas with unclear primary and secondary wind directions, and prevents sand wind from being accumulated in railway or highway road area ranges. According to the aerodynamic principle, a sand source in an implementation area can be effectively fixed, transit wind-sand flow can be prevented, the sand storm can be intercepted in a designated area far away from a protection target, and sand removal is facilitated. The cage has the advantages of high construction efficiency, low construction cost, low maintenance cost, high sand prevention benefit and the like. And after the mission is finished, the cage can be recycled.

Description

technical field [0001] The invention belongs to the technical field of engineering wind and sand prevention, and relates to a portable sand-resistance and sand-fixing cage. Background technique [0002] With the rapid development of economic construction in western my country, infrastructure construction such as railways, highways, and urban development has been widely carried out in deserts and Gobi areas in northwest my country. Sandstorms are more serious harm to railways and highways. If necessary protective measures are not taken, it will cause serious damage to infrastructures such as railways and highways, and even threaten the safe operation of infrastructures. [0003] The engineering sand-blocking measures in the prior art mainly include sand-fixing measures and sand-blocking measures. Sand blocking measures are widely used. The sand-retaining measures include concrete sleeper sand-retaining wall, PE mesh high vertical sand barrier, reed sand-retaining fence, etc...
