Embodiment 1
[0031] The present invention provides a roadbed anti-settlement structure comprising lightweight materials, including a soft soil layer 1, a waterproof layer 2, a foam concrete layer 3 and a poured pavement layer 4 in sequence from bottom to top, characterized in that the poured pavement layer There is also an anti-settling layer 5 between 4 and the foamed concrete layer 3, and the anti-settling layer 5 includes:
[0032] Profiled steel plate 6, two layers are set up and down;
[0033] There are multiple settlement compensation mechanisms 7 , which are evenly distributed between the upper and lower laminated steel plates 6 . The support body 73 , the first spring 74 and the L-shaped pressure rod 75 , the lower end of the first support body 71 and the top end of the second support body 72 are provided with mutually matching chamfered surfaces 9 , and the middle of the two chamfered surfaces 9 is along the inclined plane. There is a sliding connector for connecting the first su...
Embodiment 2
[0037] On the basis of Embodiment 1, in order to further improve the compensation settlement, a cavity 731 is provided in the third support body 73 , and an insertion section 721 is provided at the bottom of the second support body 72 , and the insertion section 721 can be inserted In the cavity 731 , the cavity 731 is further communicated with a plurality of filler inlets 732 , and the filler inlets are used for the filler between the upper and lower laminated profiled steel plates 6 to enter the cavity 731 .
[0038] In this embodiment, after the second support body 72 is raised, the insertion section 721 at the bottom of the second support body 72 moves upward, creating a gap between the second support body 72 and the cavity 731 , and the light filler will enter the cavity 731 and the insertion section 721 through the filling inlet. In the gap between, the insertion section 721 is supported and its high stability is ensured.
Embodiment 3
[0040] On the basis of Example 2, since part of the filler enters the cavity 731, the lightweight filler 8 between the upper and lower laminated steel plates 6 is reduced, which affects the reinforcement and support of the profiled steel plates 6 and the settlement compensation mechanism 7. Therefore, this implementation The example also includes an EPS board body 16, the bottom of the EPS board body 16 matches the shape of the upper surface of the upper laminated steel plate 6, and the EPS board body 16 is provided with a plurality of filling holes, and the filling holes are filled with For EPS particles, the upper laminated steel plate 6 is provided with a plurality of through holes for the EPS particles to enter between the upper and lower laminated steel plates 6 .
[0041] In this embodiment, the EPS plate body 16 is a lightweight material, and a plurality of filling holes are provided on it, and EPS particles are filled in the filling holes. There are through holes betwe...
