Description of reference numerals: 1. a roadbed; 2. a stabilizing plate; 21. a bottom; 22. a support portion; 3. a positioning column; 4. a second positioning column; 5. side slope; 51. a protective net; 52. slope protection.

Detailed Description

The present application is described in further detail below with reference to fig. 1.

As shown in fig. 1, a wind-blown sand roadbed structure, including roadbed 1, side slope 5 and stabilizer plate 2, roadbed 1 is located the middle district, stabilizer plate 2 sets up respectively in the both sides of roadbed 1, stabilizer plate 2 places on ground, side slope 5 is located the outside of stabilizer plate 2, side slope 5 from last down, is the slope form to the outside by the road inboard, roadbed 1 and side slope 5 are filled by wind-blown sand to roadbed 1 and side slope 5 bury stabilizer plate 2 in including completely. At this moment, when roadbed 1 is pressurized, stabilising plate 2 can guarantee that the difficult flow of aeolian sand in roadbed 1 and lead to sinking etc. and slope 5 can balance the pressure that 2 both sides of stabilising plate received simultaneously for stabilising plate 2 is difficult more to produce the displacement, finally reaches the effect that promotes aeolian sand roadbed structure.

As shown in fig. 1, the stabilizing plate 2 includes a bottom portion 21 and a supporting portion 22, the bottom portion 21 contacts with the ground, the supporting portion 22 is integrally connected to one side of the bottom portion 21 close to the roadbed 1, and the supporting portion 22 is generally inclined from the top to the bottom from the inside to the outside, which is more beneficial to maintaining the stability of the wind-deposited sand structure in the roadbed 1.

After long-term use, the aeolian sand in the roadbed 1 can press the stabilizing plate 2 to move outwards due to long-term pressure, and at this time, as shown in fig. 1, a positioning column 3 and a second positioning column 4 can be arranged.

As shown in fig. 1, positioning column 3 is inserted into the ground, and bottom 21 is guaranteed to be in limit abutment with positioning column 3, and at this time, stabilizing plate 2 can be limited to move outwards by the limit action of positioning column 3, so that the stability of roadbed 1 in long-term use is improved. The reference column 3 preferably passes bottom 21, can also with reference column 3 from the top down, from inside to outside slope setting, reference column 3 is more obvious to the limiting displacement of bottom 21 this moment, also can bear the bigger effort that steadying plate 2 applyed simultaneously, non-deformable.

As shown in fig. 1, the lower end of the second positioning column 4 is fixed above the ground, and the upper end of the second positioning column 4 is fixedly connected with the inner side of the supporting portion 22. Second positioning column 4 can further promote the relative stability between stabilizer plate 2 and the ground, reduces the possibility that stabilizer plate 2 takes place to remove relative ground.

Since the side slope 5 is also filled with wind-blown sand, the wind-blown sand is likely to flow in windy weather, and in order to alleviate the above problem, as shown in fig. 1, a protective net 51 may be laid on the outer side of the side slope 5, and a protection slope 52 may be pressed on the outer side of the protective net 51. The protection net 51 can reduce the ability of flowing of the wind-blown sand in the bank protection 5, and the bank protection 52 can compress the protection net 51, thereby improving the stability of the side slope 5.

In addition, the revetment 52 may be constructed using rubbles because rubbles are easy to take in desert or desert terrain and the gaps between the rubbles also help to prevent wind and fix sand and vegetation growth.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
