[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Because semi-flexible pavements are made of a mixture of various materials, workers need to place them on the surface of the roadbed during installation. However, the stability of the pavement is reduced due to the influence of ambient temperature.

[0021] In view of this, the present invention provides a semi-flexible pavement structure, which solves the problem that because semi-flexible pavements are made of a mixture of multiple materials, workers need to place them on the surface of the roadbed during paving, but the stability of the pavement is reduced due to the influence of ambient temperature.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 A semi-flexible pavement structure includes a surface layer 1, a foundation 11 below the surface layer 1, piles 15 embedded inside the foundation 11, and a cushion layer 12 above the piles 15. The cushion layer 12 is made of cement and has a reinforcing structure 3 installed inside. The reinforcing structure 3 includes: reinforcing ribs 31 inside the cushion layer 12; a connecting plate 32 fixedly connected to the bottom of the reinforcing ribs 31; a support column 33 fixedly connected to the bottom of the connecting plate 32; and a fixing frame 34 fixedly connected to the bottom of the support column 33 and the top of the piles 15 by bolts. The fixing frame 34 is connected to the foundation 11 through the cooperation of the reinforcing ribs 31 and the connecting plate 32.

[0024] In the specific implementation process, it is worth noting that the foundation 11 is used to ensure that the road surface will not sink during long-term use. The foundation 11 is generally paved and compacted with sand and gravel. The surface layer 1 is a special grouting material with high injectability, low shrinkage, high strength, rapid hardening, high wear resistance, and high crack resistance. It is made of special cement, high-quality graded granules, special redispersible latex powder, active powder, superplasticizer, setting regulator, thickener, and a variety of polymer-modified single-component special engineering materials. After being mixed with water, it is filled into the semi-flexible pavement large-void asphalt mixture. The grouting material is reinforced with reinforcing ribs 31 and connecting plates 32. The reinforcing ribs 31 are supported by fixing frames 34 to prevent the road from being damaged in harsh environments.

[0025] Furthermore, a protective net 14 is provided on the outer wall of the reinforcing rib 31, and the outer wall of the protective net 14 is embedded in the inner wall of the pad layer 12.

[0026] In the specific implementation process, it is worth noting that the reinforcing ribs 31 are wrapped with protective netting 14 to avoid the reinforcing ribs 31 affecting the padding layer 12 during the laying process and to prevent the reinforcing ribs 31 from deforming.

[0027] Furthermore, a protective layer 13 is laid at the bottom of the foundation 12, and the bottom of the protective layer 13 is laid on top of the foundation 11.

[0028] In the specific implementation process, it is worth noting that the protective layer 13 is composed of cushion soil, which separates the cushion layer 12 from the foundation 11, and prevents the foundation 11 and the cushion layer 12 from mixing together, which would lead to road instability.

[0029] Specifically, when using this semi-flexible pavement structure, the reinforcing rib 31 and the connecting plate 32 are connected during the paving process. After the connection, the supporting column 33 is used to fix it to the ground pile 15. After it is fixed, the protective net 14 is used to wrap it to prevent the reinforcing rib 31 from being deformed by the pressure of cement and to ensure the stability of the pavement under severe weather conditions.

[0030] Example 2: From Figure 1-4It is known that an adhesive layer 2 is installed at the bottom of the surface layer 1. The adhesive layer 2 includes: an upper layer 21, which is laid at the bottom of the surface layer 1 and is made of asphalt mixture; an intermediate layer 22, which is laid at the bottom of the upper layer 21 and is made of cement and crushed stone mixture; and a lower layer 23, which is laid at the bottom of the intermediate layer 22, fills the space between the intermediate layer 22 and the subbase 12, and wraps around the outer wall of the protective net 14. The lower layer 23 is made of crushed stone, which can reduce soil deformation, improve soil moisture and temperature, and play a role in drainage, water isolation, frost prevention, and pollution prevention, ensuring the stability of the surface layer and the base layer. The lower layer 23 is connected to the surface layer 1 through the cooperation of the upper layer 21 and the intermediate layer 22.

[0031] In the specific implementation process, it is worth noting that when paving the road surface, the top layer 21 and the middle layer 22 are used together to connect the surface layer 1 and the subbase layer 12, and to ensure that the road surface is not easily damaged over a long period of time.

[0032] Furthermore, a locking block 16 is fixedly connected to the bottom of the protective net 14, and the outer wall of the locking block 16 is embedded in the inner wall of the protective layer 13.

[0033] In the specific implementation process, it is worth noting that the protective net 14 is fixed inside the protective layer 13 by the card block 16 to ensure that the protective net 14 is not easily deformed when it is squeezed during slaughter.

[0034] Specifically, based on the above embodiments, the card block 16 fixes the protective net 14 to the outer wall of the reinforcing rib 31, and when laying the road surface, the adhesive layer 2 is used to connect the protective net 14 together, so that the road surface is stable when laid.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
