Description
[Technical Field]
[0001] This utility model relates to the field of roadbed technology, specifically to a roadbed reinforcement structure. [Background Technology]
[0002] With the development of transportation, vehicle loads are constantly increasing, and the challenges to road structures are becoming increasingly severe. Reinforcement measures such as retaining walls and anti-slide piles are typically used for weak foundations or steep slopes to ensure the structural stability of the roadbed under load.
[0003] For example, Chinese Utility Model Application No. "202323483022.1" discloses a municipal roadbed reinforcement structure. This patent addresses the reinforcement of roadbeds with different slopes by adjusting the angle of the reinforcement plate to adapt to the different slopes. However, such reinforcement structures are mainly installed as a remedial measure after the roadbed has been put into use. They cannot be pre-embedded inside the roadbed during the construction phase of new roads to form an integrated support. As a result, the roadbed lacks continuous structural protection under early loads or rainwater infiltration, making it prone to structural damage.
[0004] The existing roadbed reinforcement structure is difficult to meet the needs of both "new construction and pre-embedded" and "maintenance insertion" working modes, and lacks modular expansion capabilities, resulting in repeated design and construction at different project stages and low resource utilization.
[0005] In view of the above-mentioned technical problems, this invention is proposed. [Utility Model Content]
[0006] The technical problem this invention aims to solve is to provide a roadbed reinforcement structure. This structure utilizes connecting rods inserted into the bottom of the existing foundation or pre-embedded beneath the newly constructed roadbed. Adjustable support components adjust and support side-fixing plates, which press against the roadbed. The connecting rods and the side-fixing mechanism work together to enhance the connection strength between the reinforcement structure and the overall roadbed structure. This reinforcement structure can provide continuous internal support during construction to prevent early damage, and can also be inserted and installed during maintenance of existing roads, improving maintenance efficiency. This reinforcement structure effectively improves roadbed stability and reinforcement capacity, helping to extend the roadbed's service life.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a roadbed reinforcement structure, including a connecting rod, which can be inserted into the bottom of the original foundation or pre-embedded under the newly built roadbed. At least one side of the connecting rod is provided with a side fixing mechanism for supporting and fixing the roadbed. The side fixing mechanism includes a fixed base plate connected to the foundation. The upper end of the fixed base plate is hinged to a side fixing plate that abuts against the roadbed. An adjusting support component is provided between the side fixing plate and the fixed base plate for adjusting the opening and closing angle of the side fixing plate and locking it in that position, so that the side fixing plate presses against the roadbed to one side.
[0008] As described above, in a roadbed reinforcement structure, the adjustable support assembly includes a support pipe and a support rod. The support pipe is hinged to the surface of a fixed base plate, and the support rod is sleeved on the support pipe. The top end of the support rod is hinged to a side plate. The adjustable support assembly also includes an adjusting ring disposed on the support rod and threadedly connected to the surface of the support rod for adjusting the extension of the support rod and locking the support rod in that position. The adjusting ring is rotatably connected to the support pipe.
[0009] As described above, in a roadbed reinforcement structure, a connecting mechanism is provided between the connecting rod and the side fixing mechanism. The connecting mechanism includes a connecting pipe for connecting the fixed base plate and the connecting rod, and a fixing pipe provided at the end of the connecting rod. The connecting mechanism also includes fasteners for locking the connecting pipe and the fixing pipe.
[0010] As described above, in a roadbed reinforcement structure, the end of the connecting rod is provided with a connecting groove, the fixing pipe is located inside the connecting groove, and the end of the connecting pipe near the connecting groove is provided with a positioning pipe, which is fitted between the inner wall of the connecting groove and the outer wall of the fixing pipe.
[0011] As described above, a roadbed reinforcement structure includes a fixed base plate comprising a vertical panel arranged vertically relative to the foundation and a horizontal panel connected to the vertical panel. The horizontal panel is arranged horizontally relative to the foundation, and the vertical panel is connected to a connecting rod via a connecting pipe.
[0012] As described above, a roadbed reinforcement structure has several equidistantly arranged fixed anchor holes on the horizontal panel.
[0013] As described above, in a roadbed reinforcement structure, the surface of the connecting pipe is provided with a connecting part, and the vertical panel in the fixed base plate is connected and cooperated with the connecting pipe through the connecting part.
[0014] As described above, in a roadbed reinforcement structure, the side reinforcement plate has several equidistantly arranged reinforcement anchors on the side closest to the roadbed.
[0015] As described above, in a roadbed reinforcement structure, a buffer pad for sealing is also provided between the connecting groove and the fixing pipe.
[0016] As described above, in a roadbed reinforcement structure, the connecting pipe is provided with a reinforcing cross plate for strengthening the connection between the roadbed and the connecting rod, and the reinforcing cross plate has through holes inside.
[0017] Compared with the prior art, the roadbed reinforcement structure of this utility model has the following advantages:
[0018] 1. In this application, the reinforcement structure is inserted into the bottom of the existing foundation or pre-embedded under the newly constructed roadbed via connecting rods. It works in conjunction with adjustable support components to adjust and support the side reinforcement plates. The side reinforcement plates press against the roadbed, and the connecting rods and the side reinforcement mechanism work together to enhance the connection strength between the reinforcement structure and the overall roadbed structure. This reinforcement structure can provide continuous internal support during construction to prevent early damage, and can also be inserted and installed during maintenance of existing roads, improving maintenance efficiency. This reinforcement structure can effectively improve the stability and reinforcement capacity of the roadbed, helping to extend its service life.
[0019] 2. In this application, by adjusting the support assembly, the support rod extends out of the support tube and is then locked in that position, thereby providing fixation and support to the side plate to resist the roadbed. The adjustment of the support assembly fixes the bottom plate against the foundation on the side of the roadbed, and the side fixation mechanism forms a stable support structure to ensure the overall stability of the reinforced structure.
[0020] 3. In this application, by setting up a reinforcing cross plate connected to the foundation, a tethering effect can be generated with the steel bars to transfer the local load borne by the reinforcing structure to the deeper foundation material, thereby improving the shear strength between the reinforcing structure and the foundation and thus improving the overall stability of the roadbed.
[0021] 4. In this application, by inserting reinforcing anchors into the soil subgrade or pre-embedding them into the cement subgrade, the local concentrated load at the edge of the subgrade is effectively transferred and dispersed, thereby improving the overall stability and reinforcement capacity of the reinforcing structure for the subgrade.

Detailed Implementation Methods
[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0030] like Figure 1-4 As shown, this utility model includes a roadbed reinforcement structure, comprising a connecting rod 1, which can be inserted into the bottom of the existing foundation or pre-embedded under the newly constructed roadbed. At least one side of the connecting rod 1 is provided with a side-fixing mechanism 2 for supporting and fixing the roadbed. The side-fixing mechanism 2 includes a fixed base plate 201 connected to the foundation. The upper end of the fixed base plate 201 is hinged to a side-fixing plate 202 that abuts against the roadbed. An adjusting support component 21 is provided between the side-fixing plate 202 and the fixed base plate 201 for adjusting the opening angle of the side-fixing plate 202 and locking it in that position, so that the side-fixing plate 202 presses against one side of the roadbed. The reinforcement structure has two configuration modes: an existing foundation reinforcement mode with the side-fixing mechanism 2 set on one or both sides of the connecting rod 1, or a newly constructed roadbed reinforcement mode with the side-fixing mechanism 2 set on one or both sides of the connecting rod 1. Therefore, the reinforcement structure is suitable for the reinforcement and maintenance of existing old roadbeds, and also for the reinforcement measures of newly constructed roadbeds.
[0031] Depending on the road conditions, the construction team can choose either a single-sided or double-sided reinforcement mode. When one side of the roadbed is exposed and needs reinforcement, a side-stabilizing mechanism 2 can be installed on only one side of the connecting rod 1 to reinforce and support the roadbed. In this case, the reinforcement structure forms an anchoring force with the roadbed through the synergistic action of the connecting rod 1 and the side-stabilizing mechanism 2, thereby achieving the reinforcement effect on the roadbed. When both sides of the roadbed are exposed and need reinforcement, side-stabilizing structures 2 can be symmetrically installed on both sides of the connecting rod 1 to support and reinforce the roadbed. In this case, the side-stabilizing structures 2 on both sides press against and support the roadbed from both sides. The side-stabilizing structures 2 on both sides cooperate with the connecting rod 1 to generate a tensile force to balance and resist the tensile force inside the roadbed, thereby ensuring the stability and reinforcement effect of the roadbed, and effectively preventing soil erosion of the roadbed.
[0032] Specifically, the connecting rod 1 is set horizontally relative to the roadbed, and is connected to the side fixing mechanism 2 on one or both sides. For the original foundation reinforcement mode, the connecting rod 1 is inserted into the bottom of the original foundation and connected to the side fixing mechanism 2; or, for the new roadbed reinforcement mode, the connecting rod 1 is pre-embedded under the new roadbed and connected to the side fixing mechanism 2.
[0033] The reinforcement structure is inserted into the bottom of the existing foundation or pre-embedded under the newly constructed roadbed via connecting rod 1, and connected to the side reinforcement mechanism 2, so that the connecting rod 1 and the roadbed form a tight, integral connection. This, combined with the adjustable support assembly 21, adjusts and supports the side reinforcement plate 202, which in turn presses against the roadbed, effectively increasing the reinforcement effect between the reinforcement structure and the roadbed and foundation. When the roadbed bears pedestrian and vehicular traffic loads, the localized stress concentration generated between the roadbed and the reinforcement structure under gravity can be effectively transferred and dispersed to the more load-bearing roadbed or foundation soil layer through the synergistic effect between the connecting rod 1 and its connected side reinforcement mechanism 2, thereby achieving uniform load distribution and absorption.
[0034] In this application, the reinforcement structure is inserted into the bottom of the existing foundation or pre-embedded under the newly constructed roadbed via connecting rod 1. It works in conjunction with adjusting support assembly 21 to adjust and support side reinforcement plate 202. The side reinforcement plate 202 presses against the roadbed. The connecting rod 1 and the side reinforcement mechanism 2 work together to enhance the connection strength between the reinforcement structure and the overall roadbed structure. This reinforcement structure can provide continuous internal support during construction to prevent early damage, and can also be inserted and installed during maintenance of existing roads to improve maintenance efficiency. This reinforcement structure can effectively improve the stability and reinforcement capacity of the roadbed, helping to extend its service life.
[0035] like Figure 1 , Figure 2 As shown, as a further technical solution of this application, the adjustable support assembly 21 includes a support tube 211 and a support rod 212. The support tube 211 is hinged to the surface of the fixed base plate 201, and the support rod 212 is sleeved on the support tube 211. The top end of the support rod 212 is hinged to the side fixing plate 202. The adjustable support assembly 21 also includes an adjusting ring 213 provided on the support rod 212 and threadedly connected to the surface of the support rod 212 for adjusting the extension amount of the support rod 212 and locking the support rod 212 in this position. The adjusting ring 213 is rotatably connected to the support tube 211. By rotating the adjusting ring 213, the extension amount of the support rod 212 out of the support tube 211 is adjusted, thereby providing a fixing and support function for the side fixing plate 202 to resist the roadbed. The adjustable support assembly 21 stops the fixed base plate 201 against the ground on the side of the roadbed. The side fixing mechanism 2 forms a stable support structure to ensure the overall stability of the reinforced structure.
[0036] like Figure 3 , Figure 4As shown, as a further technical solution of this application, a connecting mechanism 3 is provided between the connecting rod 1 and the side fixing mechanism 2. The connecting mechanism 3 includes a connecting pipe 301 for connecting the fixed base plate 201 and the connecting rod 1, and a fixing pipe 303 provided at the end of the connecting rod 1. The connecting mechanism 3 also includes a fastener 308 for locking the connecting pipe 301 and the fixing pipe 303. Specifically, the connecting pipe 301 and the fixing pipe 303 are connected together by the fastener 308, thereby assembling the connecting pipe 301 and the connecting rod 1. Then, the fixed base plate 201 is assembled and connected to the connecting rod 1 through the connecting pipe 301. The assembly is simple and reliable.
[0037] Specifically, fastener 308 is a bolt or other conventional fastening component used for connection.
[0038] like Figure 4 As shown, as a further technical solution of this application, the end of the connecting rod 1 is provided with a connecting groove 310, the fixing tube 303 is provided inside the connecting groove 310, and the end of the connecting tube 301 near the connecting groove 310 is provided with a positioning tube 302. The positioning tube 302 is fitted between the inner wall of the connecting groove 310 and the outer wall of the fixing tube 303. The positioning tube 302 is slidably connected between the connecting groove 310 and the fixing tube 303, so that the stress distribution at the connection between the connecting rod 1 and the connecting mechanism 3 is uniform, the stability of the connection between the connecting tube 301 and the connecting rod 1 is improved, and external moisture can be prevented from entering and causing bolt corrosion, which helps to extend the service life of the reinforced structure.
[0039] The aforementioned fixed tube 303 is machined at its end to form a positioning tube 302.
[0040] Furthermore, referring to Figure 3 A buffer pad 304 for sealing is provided between the connecting groove 310 and the fixed tube 303, and one end of the positioning tube 302 abuts against the buffer pad 304. The buffer pad 304 seals the gap between the fixed tube 303 and the positioning tube 302 in the connecting groove 310, preventing moisture or other substances from entering and corroding the bolts, thereby improving the protection of the bolts and extending the service life of the reinforced structure.
[0041] Specifically, the connecting tube 301 and the positioning tube 302 can be integrally formed or welded together.
[0042] like Figure 1 , Figure 2 , Figure 4As shown, as a further technical solution of this application, the fixed base plate 201 includes a vertical panel 201a and a horizontal panel 201b connected to the vertical panel 201a. The horizontal panel 201b is horizontally arranged relative to the foundation. The vertical panel 201a is connected to the connecting rod 1 through the connecting pipe 301. The side reinforcement structure 2 is stably connected to the connecting rod 1 through the vertical panel 201a. This connection structure makes the stress distribution between the roadbed and the reinforcement structure more uniform, thereby effectively improving the stability of the entire reinforcement structure.
[0043] like Figure 1 , Figure 2 , Figure 4 As shown, furthermore, to enhance the reinforcement effect between the reinforced structure and the ground and roadbed, several equidistantly arranged fixing anchor holes 203 are provided on the transverse panel 201b. These fixing anchor holes 203 allow anchor rods (not shown in the figure) to pass through, and the anchor rods are used to connect the fixing base plate 201 to the foundation. Several equidistantly arranged reinforcing anchors 207 are provided on the side of the side plate 202 near the roadbed. In this application, the roadbed can be further reinforced by the fixing base plate 201 through the anchor rods passing through the fixing anchor holes 203, improving the fixing capacity of the reinforced structure to the roadbed. Additionally, depending on different construction needs and roadbed types, such as soil roadbeds and cement roadbeds, the reinforcing anchors 207 can be inserted into the soil roadbed or pre-embedded into the cement roadbed during use. The reinforcing anchors 207 effectively transfer and disperse the locally concentrated loads at the roadbed edge, thereby improving the overall stability and reinforcement capacity of the reinforced structure to the roadbed. It should be noted that the anchor rods are conventional fastening components used for connection.
[0044] like Figure 3 , Figure 4 As shown, as a further technical solution of this application, a connecting part 307 is provided on the surface of the connecting pipe 301. The vertical panel 201a in the fixed base plate 201 is connected and fitted to the connecting pipe 301 through the connecting part 307. The fixed base plate 201 and the connecting pipe 301 are connected and fitted together through the connecting part 307 and bolts (not shown in the figure) to assemble the two together. Correspondingly, the vertical panel 201a in the fixed base plate 201 is provided with an opening for the bolt to pass through. This application reduces the difficulty of transporting and installing the reinforcement structure through modular installation.
[0045] like Figure 3 , Figure 4As shown, as a further technical solution of this application, the connecting pipe 301 is provided with a reinforcing horizontal plate 305 for strengthening the connection between the roadbed and the connecting rod 1. A through hole 306 is provided inside the reinforcing horizontal plate 305. When pre-embedded into the bottom of the foundation, a reinforcing material such as reinforcing bars (not shown in the figure) can be passed through the through hole 306 to fix the reinforcing horizontal plate 305. The reinforcing bars generate a tethering effect, transferring the local load borne by the reinforced structure to the deeper foundation material, thereby improving the shear strength between the reinforced structure and the foundation, and thus improving the overall stability of the roadbed.
[0046] Furthermore, referring to Figure 4 The reinforcing horizontal plate 305 comprises two plates, which are kept horizontally with the foundation and are positioned symmetrically on both sides of the connecting pipe 301. After assembly, the two reinforcing horizontal plates 305 are placed outside the connecting rod 1. Specifically, the reinforcing horizontal plate 305 is horizontally positioned below the roadbed relative to the roadbed. When vehicle loads and pedestrians step on the roadbed surface, vertical pressure is transmitted to the reinforcing horizontal plate 305, which continuously compacts the reinforcing horizontal plate 305 with the surrounding roadbed material, thereby improving the overall stability of the reinforced structure and the roadbed.
[0047] This reinforcement structure is typically used for the reinforcement and maintenance of existing roadbeds or for the reinforcement of newly constructed roadbeds. When reinforcing an existing roadbed, the connecting rod 1 is first inserted into the bottom of the foundation, and the connecting pipe 301 is also inserted into the foundation. When the reinforcing horizontal plate 305 is horizontal relative to the foundation, the interaction force between the reinforcing horizontal plate 305 and the foundation is optimal. The connecting pipe 301 is then installed and connected to the connecting rod 1, and the fixed base plate 201 is then installed and connected to the connecting pipe 301 to complete the connection between the side reinforcement mechanism 2 and the connecting rod 1. Then, by rotating the adjusting ring 213, the supporting rod 212 is rotated and adjusted to adjust and fix the opening angle of the side reinforcement plate 202 relative to the fixed base plate 201, so that the side reinforcement plate 202 covers the side of the foundation. The reinforcing anchor 207 is inserted into the roadbed, and the side reinforcement mechanism 2 is pressed against the roadbed under the action of the adjusting support assembly 21 to complete the reinforcement and maintenance of the original roadbed.
[0048] During the construction of road reinforcement measures, firstly, select a connecting rod 1 of appropriate length according to the foundation width, and install and connect the connecting pipe 301 to the connecting rod 1 accordingly. Then, install and connect the fixed base plate 201 to the connecting pipe 301. Fix the reinforcement cross plate 305 by passing the steel bar through the through hole 306. Then, fill the foundation. After the foundation is compacted, rotate the adjusting ring 213 and the adjusting support rod 212 to adjust and fix the opening angle of the side plate 202 relative to the fixed base plate 201, so that the side plate 202 covers the side of the foundation to form a filling space for filling the new roadbed. Lay the roadbed and use the side plate 202 to press the roadbed. Insert the reinforcement anchor 207 into the roadbed to complete the construction of the reinforcement measures for the new roadbed.
