Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to a bedding rock section road structure. Background Art

[0002] In the field of road construction, road construction often needs to pass through unfavorable geological bodies. Bedding slope is a typical unfavorable geological body. Bedding slope refers to the slope whose inclination direction of the rock layer is close to or roughly consistent with the inclination of the layered bedrock. Bedding slope has the characteristics of large foundation bearing capacity and unstable slope. When the road passes through the bedding slope, the generally adopted measures are clearing the angle of the rock layer, setting up support reinforcement, and layered reinforcement. These measures require the excavated bedding slope to be excavated or supported according to the bedding angle. If the range of the bedding slope is large, the excavation will have a great impact on the environment, and the project scale and investment will be high. Utility Model Content

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0021] When a road needs to cross a bedding slope 6, the traditional approach is to excavate according to the bedding angle and then implement measures such as support reinforcement and layered reinforcement. However, when the bedding slope 6 is large, this method not only has a significant impact on the environment, but also significantly increases the scale and investment of the project. Based on this, this embodiment provides a road structure for a bedding rock section. Instead of excavating the bedding slope 6, anchor bars 7 are implanted into the slope 6 and columns 5 are embedded in the slope 6 to achieve fixation. This ensures the stability of the columns 5 while reducing the impact on the environment.

[0022] At the same time, considering the poor stability of the bedding slope 6 at the distribution location of the bedding rock section, the panels 2 assembled at the top of the columns 5 are used as the basic structure of the pavement layer 1, and expansion joints 3 are left between the panels 2 to absorb the unstable deformation of the bedding rock slope 6, thereby improving the adaptability of the pavement layer 1.

[0023] like Figure 1 and Figure 2 As shown, the road structure of the bedding rock section mainly includes a pavement layer 1, a panel 2 and multiple groups of columns 5. The multiple groups of columns 5 serve as the basic structure, one end of which can be embedded in the slope 6 and the other end supports the panel 2. The pavement layer 1 is laid on the panel 2 to form the required bedding rock section road structure.

[0024] Specifically, large-scale excavation of the slope 6 will destroy the original ecological environment, leading to problems such as soil erosion and vegetation destruction, and have a serious impact on the surrounding environment. The excavation of the slope 6 requires a large amount of manpower, material resources and financial resources, which not only increases the scale of the project, but also increases the investment cost. In this regard, in this embodiment, the slope 6 is not excavated on the layer slope 6. Each group of columns 5 includes a plurality of columns 5 arranged in sequence along the inclination direction of the slope 6. The columns 5 are vertically distributed and the axes of the columns 5 in the same group are coplanar. The bottom ends of the columns 5 are embedded in the slope 6, and the bottom ends of the columns 5 are connected to anchor bars 7 embedded in the slope 6.

[0025] By embedding anchor bars 7 into slope 6 and embedding columns 5 into it, the road structure is tightly integrated with slope 6. This ensures the stability of columns 5 while leveraging the inherent bearing capacity of slope 6 to support the road structure. By eliminating excavation of the bedding slope 6, the environmental damage caused by large-scale construction is avoided. Furthermore, through appropriate vegetation restoration and ecological restoration measures, the impact on the surrounding environment can be further minimized. This reduces the investment required for excavation and reinforcement of slope 6, lowering the project scale and investment costs.

[0026] In addition, if Figure 1 As shown, in order to facilitate the connection of the panels 2 , a connecting rib 4 is pre-buried at the top of the column 5 , and multiple panels 2 are arranged above the column 5 through the connecting rib 4 .

[0027] Despite reinforcement measures, the instability of the bedding rock slope 6 remains a difficult problem to solve. This is particularly true in complex geological conditions and where the rock formations are steeply inclined. To address this, in this embodiment, expansion joints 3 are provided between panels 2 to absorb the resulting sway. Specifically, transverse expansion joints 3 are provided between adjacent panels 2 in the transverse direction of the road, and longitudinal expansion joints 3 are provided between adjacent panels 2 in the longitudinal direction of the road.

[0028] Prefabricated panels 2 are used at the top of the columns 5 as the foundation structure of the pavement layer 1. This is not only convenient and quick to construct, but can also be adjusted and optimized as needed to suit different geological conditions and road requirements. Expansion joints 3 are left between the panels 2 to absorb unstable deformations of the rock slope 6 along the bed. This not only ensures the overall stability of the road structure, but also improves the adaptability of the pavement layer 1 and reduces road damage caused by deformation of the slope 6. The stability and safety of the road structure are improved through measures such as the implantation of anchor bars 7, the embedding of columns 5, and the design of expansion joints 3. Even in complex geological conditions and with large rock inclination angles, the stability and safety of the road can be guaranteed.

[0029] like Figure 1 and Figure 2 As shown, the panel 2 is an important component of the road structure and is used to support the road surface layer 1. Two panels 2 are provided above each group of columns 5. The two panels 2 are spaced apart in the transverse direction of the road, and their edges are overlapped on the middle column 5 of the same group of columns 5.

[0030] To facilitate the connection between panel 2 and column 5, a socket is provided on panel 2 for connection to connecting rib 4 at the top of column 5. Grouting is used between the socket and rib 4 to ensure a secure connection. The side of panel 2 away from the road centerline extends beyond column 5, increasing the support area and stability of panel 2.

[0031] Transverse expansion joints 3 are provided between panels 2, located above the center column 5 of the same group, to absorb lateral deformation of the bedding rock slope 6. Similarly, longitudinal expansion joints 3 are used to absorb lateral deformation of the bedding rock slope 6. The transverse expansion joints 3 between panels 2 and the longitudinal expansion joints 3 between adjacent groups of columns 5 can absorb unstable deformation of the bedding rock slope 6, improving the adaptability and durability of the road structure.

[0032] The columns 5 are used to support the panels 2 and the pavement layer 1. Each group of columns 5 includes three columns 5, which are spaced apart in sequence along the transverse direction of the road. The columns 5 are distributed vertically and the axes of the columns 5 in the same group are coplanar, ensuring the overall stability of the road structure. When the road bears vehicle loads, it can evenly distribute the load and reduce structural damage caused by excessive local stress. Specifically, two panels 2 are arranged in sequence along the transverse direction of the road. The edges of the two panels 2 are overlapped on the middle column 5 of the same group of columns 5, and the transverse expansion joint 3 is located above the middle column 5. Multiple groups of columns 5 are spaced apart in sequence along the longitudinal direction of the road, and the longitudinal expansion joint 3 between adjacent groups of columns 5 is located above the columns 5.

[0033] like Figure 1 and Figure 2 As shown, in road structures, the road is affected by various factors during use, such as temperature, humidity, and load, causing the road material to expand and contract, deform, and so on. Without expansion joints 3, these deformations would lead to stress concentration within the road structure, causing cracks, damage, and other problems. Therefore, in this embodiment, the provision of expansion joints 3 can absorb deformation of the road structure caused by factors such as temperature changes and loads, thereby preventing excessive stress from being generated within the structure. Expansion joints 3 ensure that the road remains flat despite deformation, without affecting driving safety and comfort.

[0034] Asphalt hemp is filled into the expansion joint 3. Asphalt hemp offers excellent sealing properties, effectively preventing moisture and debris from entering the expansion joint 3 and damaging the road structure. Asphalt hemp exhibits a certain degree of elasticity, adapting to minor deformations in the road structure and maintaining the flexibility and functionality of the expansion joint 3. Asphalt hemp exhibits excellent durability and aging resistance, maintaining its performance over long-term use. The application of asphalt hemp is relatively simple, allowing for quick and effective filling of the expansion joint 3, improving construction efficiency and ensuring the stability and reliability of the road structure over the long term.

[0035] The bottom end of the column 5 is embedded in the slope 6 and is connected to an anchor bar 7. One end of the anchor bar 7 is embedded in the slope 6 and the other end is connected to the steel skeleton of the reinforced concrete column, which enhances the connection strength between the column 5 and the slope 6 and improves the anti-overturning ability of the entire road structure.

[0036] Connecting ribs 4 are pre-embedded at the tops of the columns 5, connecting them to the sockets on the panels 2. The assembled connection between the panels 2 and the columns 5 simplifies the construction process and improves efficiency. On-site construction workers can quickly and accurately assemble the road structure, shortening the construction period.

[0037] Pavement layer 1 is the final layer of the road structure, directly bearing vehicle loads. Pavement layer 1 is laid on top of panels 2, and its stability and flatness are maintained by the support of panels 2 and columns 5. Guardrails are installed on both sides of pavement layer 1 to ensure driving safety.

[0038] An opening for matching the connector is left on the bottom surface of the guardrail. The connector passes through the road surface layer 1 and matches the guardrail, which facilitates the installation and disassembly of the guardrail and improves the stability and firmness of the guardrail.

[0039] Specifically, connectors must possess sufficient strength and rigidity to withstand the loads of guardrails and vehicles, ensuring the safety and stability of the road structure. Connectors should be constructed of corrosion-resistant materials, such as stainless steel or galvanized steel, to extend their service life. Connectors should also be easy to install, minimizing both difficulty and cost.

[0040] In this embodiment, the connector can be made of cylindrical, square, or conical shapes, such as rebar, I-beam, or channel steel, to accommodate various installation requirements. The connector's diameter or side length should be determined based on the guardrail specifications and the road structure's load-bearing capacity. One end of the connector connects to the embedded surface component, perhaps by welding or bolting; the other end penetrates pavement layer 1 and engages the guardrail, perhaps by threading or snap-fitting.

[0041] Guardrails can be constructed in various shapes, including corrugated, column-shaped, and beam-shaped, to accommodate different road types and vehicle speed requirements. Materials available for guardrails include steel, aluminum alloy, and fiberglass. The underside of the guardrail should include openings for connectors. The shape, size, and location of the openings should match the connectors to ensure a secure and reliable connection. The guardrail and connectors can be connected using threaded or snap-on connections, ensuring a stable connection and easy disassembly and maintenance.

[0042] Guardrails are installed on both sides of pavement layer 1 to ensure driving safety, effectively preventing vehicles from running off the road and reducing traffic accidents. Pavement layer 1 is laid on top of panel 2 and supported by panels 2 and columns 5 to maintain its stability and flatness. This provides a stable driving surface and improves driving safety.

For those skilled in the art, any equivalent modifications or substitutions made to the utility model are also within the scope of the utility model. Therefore, equivalent changes, modifications, and improvements made without departing from the spirit and scope of the principles of the utility model should be included within the scope of the utility model.
