If these wastes are not effectively utilized, not only a large amount of land resources will be occupied, but also pollution to the environment may be caused.

[0003] It is a popular technology to crush inorganic waste materials and use them for road paving.

[0027] Example 1

[0028] Example 1 provides a kind of roadbed structure based on regenerative inorganic material, as shown in the drawing, specific structure is as follows description. Figures 1-4 ​

[0029] As shown in Figure 1 and Figure 2 illustrated, the roadbed structure based on the recycled inorganic material of the embodiment 1 mainly includes five parts of a roadbed base 1, a support frame 2, a recycled inorganic material prefabricated block 3, a dense hardening layer 4 and a road surface surface layer 5, wherein the roadbed base 1 serves as a bottom layer, the support frame 2, the recycled inorganic material prefabricated block 3 and the dense hardening layer 4 serve as main support layers, and the road surface surface layer 5 serves as a top layer.

[0030] Further, as shown in Figure 2 , the roadbed base 1 is paved with gravel and compacted by a road roller. As shown in Figure 1 and Figure 2 , the support frame 2 can be a prefabricated cement frame, which is formed in advance in a cement plant and has good support strength, so that it can be directly used after being transported to the construction site, thereby improving the construction efficiency. As shown in Figure 1 , the support frame 2 is composed of a plurality of longitudinal and transverse intersecting cement plates, and square installation holes 201 are formed in the inside of the support frame 2, and a plurality of installation holes 201 are arranged in the support frame 2.

[0031] Further, as shown in Figure 1 , four splicing holes 202 are arranged on the left side of the support frame 2, and four splicing holes 202 are also arranged on the right side of the support frame 2, when two support frames 2 are closely paved along the roadbed base 1, the splicing holes 202 of the two support frames 2 are close to alignment, the splicing hole 202 is half the size of the installation hole 201, and the two splicing holes 202 form a complete installation hole 201 after splicing.

[0032] In some embodiments of the embodiment, the recycled inorganic material prefabricated block 3 is also prefabricated in a cement plant, thereby improving the efficiency of road site construction. As shown in Figure 1 and Figure 4 , the recycled inorganic material prefabricated block 3 mainly includes two parts of a sleeve 301 and a recycled inorganic material embedded block 302, the sleeve 301 can be made of a metal material, and a fish scale mesh 303 inclined to the upper side is arranged on the outer surface of the sleeve 301, a plurality of fish scale meshes 303 are uniformly distributed on the outer surface of the sleeve 301, and the fish scale mesh 303 is similar to a fish scale shape.

[0033] Further, as shown in Figure 4 , the recycled inorganic material prefabricated block 3 is mixed with cement after the inorganic waste material is crushed, and then poured into the sleeve 301 after stirring, and solidified and formed in the sleeve 301 after a period of time, so that the sleeve 301 and the recycled inorganic material embedded block 302 form an integral whole.

[0034] It should be noted that, as shown in Figure 1As shown, the sleeve 301 can be punched by a puncher to form punched pieces (i.e. fish scale mesh 301), and punched holes 304 are formed at the positions where the sleeve 301 is punched. Before pouring, the punched holes 304 and the gaps of the punched pieces can be blocked by clay, and the inorganic waste material mixed cement has certain viscosity, so that the inorganic waste material mixed cement will not flow out of the punched holes 304 after pouring, and can be normally solidified and formed. After forming, the dry clay can be knocked off.

[0035] In this embodiment, fixed nails can also be inserted into the side wall of the sleeve 301 and extend into the inside of the sleeve 301. After pouring, the fixed nails and the regenerated inorganic material block 302 are fixed, and the sleeve 301 and the regenerated inorganic material block 302 are more stable.

[0036] In combination Figure 1 As shown, since the maximum diameter of the regenerated inorganic material precast block 3 is smaller than the side length of the installation hole 201, the regenerated inorganic material precast block 3 can be directly placed into the installation hole 201 during installation. Since the fish scale mesh 303 is inclined upward, it can be placed into the installation hole 201 by knocking. After being placed, a dense hardening layer 4 is arranged in the gap between the regenerated inorganic material precast block 3 and the installation hole 201. The dense hardening layer 4 is a cement layer, which is vibrated and compacted after the installation hole 201 is filled with cement, and the support frame 2 and the regenerated inorganic material precast block 3 form an integral whole after solidification.

[0037] It should be noted that for ordinary pavement, the area occupied by the regenerated inorganic material precast block 3 is greater than the area occupied by the support frame 2, the size of the installation hole 201 is increased, and the use of the material of the support frame 2 is reduced, thereby further saving raw materials.

[0038] The pavement surface layer 5 is a cement layer or an asphalt layer, which is laid on the top of the support frame 2 and the regenerated inorganic material precast block 3.

[0039] Embodiment 2

[0040] In this embodiment, the support frame 2 can be provided in two layers to increase the height of the regenerated inorganic material-based roadbed structure.

[0041] In combination Figure 3 As shown, the protrusions 203 are installed at the bottom of the side edges (specifically, the side edges of the two sides of the road) of the upper layer of support frames 2, and the insertion slots 204 are provided at the top of the side edges (specifically, the side edges of the two sides of the road) of the lower layer of support frames 2. When the upper layer of support frames 2 is installed, the protrusions 203 are inserted into the insertion slots 204 in alignment, which plays a good fixing role.

[0042] In comparison Figure 1 When the upper layer of support frames 2 is installed, the upper layer of support frames 2 is staggered with the lower layer of support frames 2, so that the longitudinal plates of the upper layer of support frames 2 are aligned with the centers of the installation holes 201 of the lower layer of support frames 2. The staggered structure is more stable.

[0043] The working principle of the roadbed structure based on the recycled inorganic material is as follows:

[0044] The roadbed structure based on the recycled inorganic material comprises a roadbed base 1, a support frame 2, a recycled inorganic material prefabricated block 3, a dense hardening layer 4 and a road surface layer 5. The recycled inorganic material prefabricated block 3 is used to replace part of the concrete, which saves the concrete raw materials and reduces the pollution to the environment. The recycled inorganic material prefabricated block 3 is installed in the support frame 2 and is connected by the dense hardening layer 4. The recycled inorganic material prefabricated block 3 and the support frame 2 form an integral whole, which has better strength and stress performance and has a longer service life compared with the traditional mixed inorganic material roadbed.

[0045] In summary, the roadbed structure based on the recycled inorganic material comprises a roadbed base 1, a support frame 2, a recycled inorganic material prefabricated block 3, a dense hardening layer 4 and a road surface layer 5. The recycled inorganic material prefabricated block 3 is used to replace part of the concrete, which saves the concrete raw materials and reduces the pollution to the environment.

The recycled inorganic material prefabricated block 3 and the support frame 2 form an integral whole, which has better strength and stress performance and has a longer service life compared with the traditional mixed inorganic material roadbed.
