Description

Technical Field

[0001] This utility model relates to the field of roadbed support and protection, specifically to a roadbed support and protection device. Background Technology

[0002] In the process of modern transportation infrastructure construction, the roadbed, as a core component of the road structure, plays a crucial role. It not only bears the heavy responsibility of transmitting vehicle loads but also needs to maintain road stability and effectively prevent pavement deformation. However, with the continuous increase in traffic volume and the increasing complexity and variability of environmental conditions, the roadbed is facing a series of potential risks, including settlement, deformation, water seepage, and soil loosening. These risks not only shorten the expected service life of the road but also pose a substantial crisis to traffic safety. Therefore, implementing effective support and protection for the roadbed to prevent damage from external factors has become a key aspect of roadbed construction.

[0003] However, most existing support and protection devices adopt an integrated fixed design, which makes it difficult to flexibly adjust to specific slope conditions when facing different terrains and slopes, greatly reducing the adaptability and application effectiveness of the support devices. In addition, existing anchor bolts are usually equipped with only simple threaded structures, which makes it difficult to enhance the friction between the protection device and the soil, thereby affecting the stability and reliability of its connection with the roadbed, and thus reducing the support effect and stability of the support and protection device.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a support and protection device for roadbeds to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A roadbed support and protection device includes a protective frame, with support components at both ends of the protective frame and the support components being laterally connected. One side of the protective frame is connected to the inclined surface of the roadbed, and the protective frame and the roadbed are fixed by a number of expansion bolts. The support components are fixed to the roadbed by a number of anchor rods. A drainage component is provided on the side of the roadbed near the protective frame, and a drainage channel that cooperates with the drainage component is opened at the top of one side of the roadbed.

[0008] Furthermore, in order to achieve rapid assembly of the support and protection device and improve work efficiency, a protective net is installed inside the protective frame, a limiting hole is opened on one side of the protective frame to cooperate with the expansion bolt, and a limiting block is opened at both ends of the protective frame to cooperate with the support component.

[0009] Furthermore, to improve adaptability to various terrains and slopes and optimize the distribution and bearing capacity of external loads, the support assembly includes a support plate set on one side of the roadbed. The two ends of the support plate are provided with limiting grooves that cooperate with limiting blocks. One side of the support plate is provided with a positioning hole that cooperates with an anchor rod. The side of the support plate away from the roadbed is provided with a groove. A movable plate is provided at the bottom of the support plate, and the movable plate cooperates with the support plate through a hinge. The top of the movable plate is provided with a positioning hole that cooperates with an anchor rod. The middle of the movable plate is provided with a protrusion that cooperates with the groove, and the groove and the protrusion are fixed by a limiting strip.

[0010] Furthermore, in order to enhance the tight connection between the support and protection device and the roadbed and significantly improve the overall stability of the structure, the anchor rod includes a support rod installed inside positioning hole one and positioning hole two. The top of the support rod is provided with an installation plate, and the bottom of the support rod is provided with several connecting columns. The bottom of the connecting columns is provided with reinforcing parts. The outer circumference of the support rod is provided with threads.

[0011] Furthermore, in order to effectively prevent water accumulation caused by poor drainage and the potential damage to the roadbed, the drainage component includes a filter box installed on one side of the roadbed. The top of the filter box has several filter holes, and both ends of the filter box are equipped with drainage pipes that cooperate with the drainage channel.

[0012] Furthermore, in order to further enhance the connection strength between the support and protection device and the roadbed, and improve the overall structure's ability to withstand external loads and its stability, the reinforcement is a continuous cone structure, and the diameter of the cone section decreases in a stepped manner.

[0013] Furthermore, to ensure that the support and protection device can be firmly fixed to the roadbed and provide support and protection for the roadbed, the thread has an equidistant spiral structure.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the cooperation of the protective frame and the support components, the support and protection device can be quickly assembled according to different slope conditions, thereby significantly reducing the construction difficulty and shortening the installation time. It not only greatly improves the adaptability of the support and protection device to various terrains and slopes, but also effectively improves the overall work efficiency.

[0016] 2. By setting up support components, this utility model can be flexibly adjusted according to different roadbed conditions, ensuring that the support and protection device can fit tightly against the roadbed surface, thereby significantly improving the adaptability to various terrains and slopes, and thus optimizing the distribution and bearing performance of external loads.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a support and protection device for roadbeds is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the configuration method according to the embodiment of this utility model includes a protective frame 1, with support components 2 provided at both ends of the protective frame 1, and the protective frame 1 and the support components 2 are laterally connected. One side of the protective frame 1 is connected to the inclined surface of the roadbed 3, and the protective frame 1 and the roadbed 3 are fixed by a number of expansion bolts 4. The support components 2 and the roadbed 3 are fixed by a number of anchor rods 5. A drainage component 6 is provided on the side of the roadbed 3 near the protective frame 1, and a drainage groove 7 that cooperates with the drainage component 6 is opened at the top of one side of the roadbed 3.

[0030] By utilizing the aforementioned technical solution of this utility model, through the cooperation of the protective frame 1 and the support component 2, the support and protection device can be quickly assembled according to different slope conditions, thereby significantly reducing construction difficulty and shortening installation time. This not only greatly improves the adaptability of the support and protection device to various terrains and slopes but also effectively enhances overall work efficiency. By setting the support component 2, it can be flexibly adjusted according to different roadbed conditions, ensuring that the support and protection device can closely fit the roadbed surface, thereby significantly improving its adaptability to various terrains and slopes, and further optimizing the distribution and bearing capacity of external loads.

[0031] In one embodiment, the protective frame 1 has a protective net 101 inside, a limiting hole 102 that cooperates with the expansion bolt 4 on one side, and limiting blocks 103 that cooperate with the support component 2 at both ends, thereby realizing the rapid assembly of the support and protection device and improving work efficiency.

[0032] In one embodiment, the support component 2 includes a support plate 201 disposed on one side of the roadbed 3. The support plate 201 has limiting grooves 202 at both ends that cooperate with limiting blocks 103. One side of the support plate 201 has a positioning hole 203 that cooperates with anchor rods 5. The side of the support plate 201 away from the roadbed 3 has a groove 204. A movable plate 205 is disposed at the bottom of the support plate 201, and the movable plate 205 cooperates with the support plate 201 via a hinge 206. The top of the movable plate 205 has a positioning hole 207 that cooperates with anchor rods 5. A protrusion 208 that cooperates with the groove 204 is disposed in the middle of the movable plate 205. The groove 204 and the protrusion 208 are fixed together by limiting strips 209, thereby improving adaptability to various terrains and slopes and optimizing the distribution and bearing capacity of external loads.

[0033] The working principle of the support component 2 is as follows: After initial fixation, the staff first pulls out the limiting strip 209, and with the assistance of the hinge 206, adjusts the movable plate 205 to fit tightly against one side surface of the roadbed 3; then, according to actual needs, select the corresponding positioning hole (positioning hole one 203 or positioning hole two 207), pass the anchor rod 5 through the selected positioning hole and firmly insert it into the roadbed 3, so as to further enhance the connection strength between the support protection device and the roadbed, and improve the overall structure's ability to withstand external loads and its stability.

[0034] In one embodiment, the anchor rod 5 includes a support rod 501 disposed inside the positioning hole 203 and the positioning hole 207. The top end of the support rod 501 is provided with a mounting plate 502, and the bottom end of the support rod 501 is provided with a plurality of connecting posts 503. The bottom end of the connecting posts 503 is provided with a reinforcing member 504. The outer circumference of the support rod 501 is provided with a thread 505, thereby enhancing the tight connection between the support and protection device and the roadbed and significantly improving the overall stability of the structure.

[0035] In one embodiment, the drainage component 6 includes a filter box 601 disposed on one side of the roadbed 3. The top of the filter box 601 is provided with a plurality of filter holes 602. Both ends of the filter box 601 are provided with drainage pipes 603 that cooperate with the drainage channel 7, thereby effectively preventing water accumulation problems caused by poor drainage and the roadbed damage that may be caused.

[0036] In one embodiment, the reinforcement 504 is a continuous cone structure with the diameter of the cone section decreasing in a stepped manner, thereby further enhancing the connection strength between the support and protection device and the roadbed, and improving the overall structure's ability to withstand external loads and its stability.

[0037] In one embodiment, the thread 505 is an equidistant helical structure, thereby ensuring that the support and protection device can be firmly fixed on the roadbed, providing support and protection for the roadbed.

[0038] It should be noted that the expansion bolt 4 is a fastener commonly used to fix heavy objects to hard materials such as concrete or brick. Its structure typically includes three parts: a bolt, a tapered sleeve, and an expansion tube. Its working principle is mainly based on rotating the bolt, causing the tapered sleeve to advance along the bolt's threads, pushing the expansion tube outwards, thus tightly pressing it against the inner wall of the drilled hole to form a secure fixing point. When the bolt is fully tightened, the friction between the expansion tube and the drilled hole wall increases significantly, ensuring the fixed object remains stable. This is existing technology and will not be elaborated upon further here.

[0039] Hinges 206 are typically composed of two symmetrical or asymmetrical metal blades connected by a pin. Some structures include bearings to reduce friction. Their working principle is based on the rotational freedom provided by the pin, allowing the two blades to rotate relative to each other around the axis while restricting displacement in other directions, thus enabling flexible opening and closing or angle adjustment between components. By optimizing the contact surface design and material strength between the pin and the blades, the hinge can withstand axial loads and shear forces while maintaining stability during repeated rotations. It is widely used in doors and windows, mechanical joints, folding structures, and other applications requiring controllable rotation and reliable support. This is existing technology and will not be elaborated further here.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0041] In practical application, firstly, workers place the protective frame 1 and support component 2 on one side of the roadbed 3, and assemble the support and protection device on-site according to the specific conditions of the roadbed surface. The limiting block 103 on one side of the protective frame 1 is inserted into the corresponding limiting groove 202 of the support component 2 to ensure a tight fit. Then, expansion bolts 4 are used to pass through the limiting holes 102 and fix them to the roadbed, completing the initial and stable support and protection of the roadbed. Next, through the cooperation of the support component 2 and the anchor rod 5 (the working principle of the support component 2 is as described above), further enhancement is achieved. The strong support and protection of the roadbed ensures that the entire structure can withstand external loads and maintain stability. Finally, the drainage component 6 is installed. When heavy rain occurs, rainwater on the top of the roadbed 3 will flow into the filter box 601 through the filter hole 602. During this process, larger solid materials such as leaves and stones will be effectively intercepted to avoid blockage. The rainwater that has undergone preliminary filtration will be smoothly discharged into the diversion channel 7 through the drainage pipe 603, ensuring that the drainage system is unobstructed, thereby effectively preventing water accumulation problems caused by poor drainage and the roadbed damage that may be caused.

[0042] In summary, by utilizing the above-mentioned technical solution of this utility model, through the cooperation of the protective frame 1 and the support component 2, the support and protection device can be quickly assembled according to different slope conditions, thereby significantly reducing construction difficulty and shortening installation time. This not only greatly improves the adaptability of the support and protection device to various terrains and slopes but also effectively enhances overall work efficiency. By setting the support component 2, it can be flexibly adjusted according to different roadbed conditions, ensuring that the support and protection device can closely fit the roadbed surface, thus significantly improving its adaptability to various terrains and slopes, and optimizing the distribution and bearing performance of external loads. By setting the reinforcing member 504 and the thread 505, the tight connection between the support and protection device and the roadbed is enhanced, which not only significantly improves the overall stability of the structure but also ensures that the support and protection device can be firmly fixed to the roadbed, thereby providing reliable support and protection for the roadbed.
