Description

Technical Field

[0001] This invention relates to the field of municipal road engineering technology, specifically to a municipal roadbed reinforcement structure. Background Technology

[0002] Municipal road engineering is an important component of urban infrastructure. It refers to civil engineering projects within the urban planning area that construct carriageways, sidewalks, green belts, ancillary pipelines, and traffic supporting facilities. These projects serve the function of facilitating the passage of people and vehicles in urban areas, while also taking into account the laying of underground pipelines, and serving the daily operation of the city and traffic management.

[0003] Most existing conventional municipal roadbeds adopt a construction method of layered filling and crushed stone compaction. When vehicles repeatedly pass through and apply heavy loads, the roadbed load can only be dispersed by the layered filling. This can easily cause local stress accumulation under the wheels. Over time, the roadbed soil will continuously consolidate and shrink, which can easily lead to local settlement, resulting in uneven road surface and ultimately reduced road surface smoothness.

[0004] Therefore, we propose a roadbed reinforcement structure for municipal roads to address the problems mentioned above. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-10This invention provides a technical solution: a municipal roadbed reinforcement structure, comprising: a roadbed body 1 composed of compacted natural soil; and a compression-resistant component 2, which is embedded inside the roadbed body 1. The compression-resistant component 2 includes multiple columns 201, each column 201 having two opposing reinforcement plates 202 fixedly connected to its outer surface. Each pair of adjacent reinforcement plates 202 forms a group, and multiple longitudinal main beams 204 arranged parallel to each other in a circumferential direction are fixedly connected between the outer surfaces of the multiple groups of reinforcement plates 202. The multiple longitudinal main beams 204 are evenly divided into multiple groups. Multiple curved secondary beams 205, bent and evenly arranged along the arch direction, are fixedly connected to the outer surfaces of the multiple sets of longitudinal main beams 204. Multiple evenly arranged diagonal main beams 206 are fixedly connected to both sides of the multiple sets of longitudinal main beams 204. Arch head connecting columns 207 are fixedly connected to the outer surfaces of the multiple sets of diagonal main beams 206. Transverse connecting rods 208 are fixedly connected to one side of the multiple sets of arch head connecting columns 207. Multiple evenly arranged connecting beams 209 are fixedly connected to the outer surfaces of the multiple sets of reinforcing plates 202. Drainage component 3 is embedded inside the compression-resistant component 2. Drainage component 3 includes components opened in the column 201. Multiple grooves 301 at the center of the inner wall and multiple columns 201 are fixedly connected to transverse support arms 302 on their outer surfaces; reinforcement components 4 are laid on top of the roadbed body 1, multiple reinforcement plates 202, and multiple evenly arranged strong threaded nails 203 are fixedly embedded between the inner walls on both sides of each adjacent pair of reinforcement plates 202; multiple longitudinal main beams 204 are evenly divided into multiple groups, multiple arc-shaped secondary beams 205 are evenly divided into multiple groups, and the multiple groups of longitudinal main beams 204 are respectively connected to multiple groups of The arc-shaped secondary beams 205 are arranged in a spatially orthogonal cross pattern, together forming a spatially hollowed-out arched grid structure load-bearing base. One end of multiple transverse connecting rods 208 is fixedly connected to one end of multiple inclined main beams 206. The top limiting frame is composed of the arch head connecting column 207, transverse connecting rods 208 and inclined main beams 206. The upper surface of multiple transverse support arms 302 is fixedly connected with arc-shaped comb tooth components 303 along its own length direction. The inner walls of multiple groove arcs 301 are all fixedly embedded with pipes 304.

[0023] In this embodiment, when using the municipal roadbed reinforcement structure, the construction site must first be leveled, cleaned, and marked out. The roadbed trench is then excavated according to the designed width and depth. The natural soil within the trench is layered and compacted evenly using a compaction machine to form a stable roadbed body 1 with adequate bearing capacity. Subsequently, holes are precisely drilled on the roadbed body 1 according to the designed spacing. The columns 201 of the anti-compression component 2 are vertically inserted into the holes and fixed, making the columns 201 the main vertical bearing components within the roadbed, directly bearing and transmitting the vertical load from the superstructure. Reinforcement plates 202 are symmetrically installed on the outside of the columns 201, and strong threaded nails 203 are used to penetrate the reinforcement plates 202 and connect them to the columns 201. Locking and fixing the reinforcing plate 202 and the column 201 together forms a rigid integrated structure, significantly improving the lateral bending, shear, and deformation resistance of the column 201 and preventing bending, tilting, and local instability of the column under load. Then, using multiple sets of adjacent reinforcing plates 202 as support units, longitudinal main beams 204 are installed parallel to each other along the circumference, firmly connecting the longitudinal main beams 204 to the reinforcing plates 202. This makes the longitudinal main beams 204 form a continuous main load-bearing component along the roadbed extension direction, bearing and distributing longitudinal tensile and compressive stresses. Next, arc-shaped secondary beams 205, bent along the arch curvature direction, are installed on the longitudinal main beams 204, so that the longitudinal main beams 204 and the arc-shaped secondary beams 205 are arranged spatially orthogonally, together forming a hollow... The hollow arched grid structure utilizes the unique stress characteristics of an arch to rapidly transform concentrated loads into axial pressure and diffuse it outwards, significantly improving the overall compressive, impact, and settlement resistance of the roadbed. Simultaneously, the hollow structure reduces self-weight and enhances soil cohesion and drainage. Meanwhile, diagonal main beams 206 are installed on both sides of the longitudinal main beam 204, with arch-head connecting columns 207 connected to the ends of the diagonal main beams 206. Transverse connecting rods 208 are erected between the arch-head connecting columns 207, forming a top-end limiting frame that laterally constrains and limits the top of the arched grid structure, counteracting the outward expansion force and lateral displacement generated under load, and maintaining the overall integrity of the framework. To ensure stability and prevent outward deformation of the space frame structure, connecting beams 209 and connecting rods 216 are installed between multiple sets of reinforcing plates 202, connecting all columns 201 laterally into a continuous and integrated load-bearing skeleton. This allows each column and each space frame unit to work together to avoid stress concentration and local damage caused by independent bearing of individual components, thus comprehensively improving the overall stiffness and compressive bearing capacity of the roadbed. This device forms an integrated load-bearing skeleton through the columns 201, reinforcing plates 202 and spatial arched space frame. With the top limiting frame constraining lateral deformation, it can quickly and evenly distribute concentrated vehicle loads, greatly improving the roadbed stiffness and impact resistance. This ensures that the road can be used for a long time without collapsing, sinking or cracking, effectively guaranteeing the smoothness of the road surface.

[0024] like Figure 1-10As shown, multiple pipes 304 have pads 305 fixedly connected to their inner walls near one end. Each pad 305 has a cap 306 fitted to one side. The outer surfaces of each cap 306 have slots. Multiple pipes 304 have round caps 307 fixedly fitted to their outer surfaces near one end. Multiple slots 301 are respectively formed at the center of the inner walls of multiple columns 201. Multiple inclined columns 308 are fixedly connected to the outer surfaces of each round cap 307 near the edge, arranged evenly along the circumference. The inclined columns 308 are divided into multiple groups, with one end of each group fixedly connected to one end of each column 201. Multiple vertical columns 309 are fixedly connected to the outer surfaces of each round cap 307 near the center, arranged evenly along the circumference. The vertical columns 309 are divided into multiple groups, and one end of each group of vertical columns 309 is fixedly connected to one end of each column 201. The reinforcement component 4 includes a cushion layer 401 composed of hard crushed stone, which is laid on top of the roadbed 1. A base layer 402 composed of fine sand and gravel mixture is laid on top of the cushion layer 401, and a surface layer 403 composed of asphalt concrete is laid on top of the base layer 402. Each pair of multiple reinforcement plates 202 is a group, and multiple evenly arranged connecting rods 216 are fixedly connected between the outer surfaces of both sides of the multiple groups of reinforcement plates 202. Multiple drainage arc pipes 310 for drainage are laid inside the cushion layer 401 near the base layer 402, and the multiple drainage arc pipes 310 are located between the outer surfaces of the multiple columns 201.

[0025] In this embodiment, the drainage component 3 has a groove 301 at the center of the inner wall of the column 201. The pipe 304 is embedded and fixed inside the groove 301. A horizontal support arm 302 is connected to the outside of the column 201. A pad 305 is installed at one end of the inner wall of the pipe 304. A cap 306 is placed against the pad 305 and mates with the pipe 304. A round cap 307 is fitted onto the end of the pipe 304. An inclined column 308 and a vertical column 309 are installed on the outside of the round cap 307. The inclined column 308 and the vertical column 309 are fixed to the end of the column 201 to ensure drainage. Pipe 304 is stable and does not shift. At the same time, drainage arc pipe 310 is laid inside the subbase 401 near the base course 402 to form a three-dimensional drainage system for the roadbed. After the road is put into use, rainwater seeps down through the gaps in the surface layer 403 and, together with the drainage arc pipe 310, quickly drains the accumulated water to the outside of the roadbed. This device forms a deep and shallow dual drainage path through pipe 304 and drainage arc pipe 310, which quickly drains the water inside the roadbed, prevents soil softening, frost heave and erosion, effectively avoids water damage to the roadbed and improves the drainage and anti-clogging effect of this device.

[0026] like Figure 1-10As shown, the interior of the base layer 402 near the top of the subbase 401 is provided with a plurality of perforated mesh-shaped first interception plates 210 for intercepting soil particles. The plurality of first interception plates 210 are respectively located between the outer surfaces of adjacent columns 201. The outer surface of the first interception plates 210 has a plurality of uniformly arranged first circular grooves 211. The interior of the subbase 401 near the top of the road base body 1 is provided with a plurality of perforated mesh-shaped second interception plates 212 for intercepting soil particles. The plurality of second interception plates 212 are respectively located between the outer surfaces of adjacent columns 201. The outer surface of the second interception plates 212 has a plurality of uniformly arranged second circular grooves 213. The interior of the road base body 1 is provided with a plurality of perforated mesh-shaped third interception plates 214 for intercepting soil particles. The plurality of third interception plates 214 are respectively located between the outer surfaces of adjacent columns 201. The outer surface of the third interception plates 214 has a plurality of uniformly arranged third circular grooves 215.

[0027] In this embodiment, reinforcement components 4 are laid from bottom to top on the top of the roadbed 1. First, a subbase 401 composed of hard crushed stone is laid and compacted. A second intercepting plate 212 is embedded inside the subbase 401 near the roadbed 1. A base course 402 composed of fine sand and gravel mixture is laid on top of the subbase 401. A first intercepting plate 210 is embedded inside the base course 402 near the subbase 401. A third intercepting plate 214 is embedded inside the roadbed 1 and between the columns 201. The three layers of intercepting plates intercept soil particles and prevent roadbed erosion through their own circular groove structure. Finally, an asphalt concrete surface layer 403 is laid on top of the base course 402 and compacted. After the road is put into use, rainwater seeps down through the gaps in the surface layer 403, and is quickly drained by the drainage arc pipe 310. The system quickly drains accumulated water from the outside of the roadbed to prevent soil softening and settlement. Vehicle loads are sequentially transferred through the surface layer 403, base layer 402, and subbase layer 401 to the compression-resistant component 2. The load is vertically supported by the column 201, horizontally dispersed by the arched grid base, and constrained by the top limiting frame, thus evenly transferring the load to the entire roadbed body 1. At the same time, the multi-layer interception plates and the overall skeleton constrain soil displacement, maintaining the stability of the roadbed structure in the long term, preventing collapse, cracking, and settlement. This device uses three layers of hollow interception plates arranged inside the roadbed body 1, subbase layer 401, and base layer 402, combined with connecting rods 216 and connecting beams 209 to form a full-area constraint structure. This structure allows water to pass through while intercepting soil particle loss, keeping the roadbed dense and stable in the long term and significantly extending the service life of the road.

[0028] The usage and working principle of this device: When using this municipal roadbed reinforcement structure, the construction site must first be leveled, cleaned, and marked out. The roadbed trench is then excavated according to the designed width and depth. The natural soil in the trench is spread in layers and compacted evenly using a compaction machine to form a stable roadbed body 1 with adequate bearing capacity. Subsequently, holes are precisely drilled on the roadbed body 1 according to the designed spacing. The columns 201 of the anti-compression component 2 are vertically inserted into the holes and fixed, making the columns 201 the main vertical bearing components inside the roadbed, directly bearing and transmitting the vertical load from the superstructure. Symmetrical installations are then made on the outside of the columns 201. The reinforcing plate 202 is secured to the column 201 using strong threaded nails 203, forming a rigid integrated structure that significantly improves the lateral bending, shear, and deformation resistance of the column 201, preventing bending, tilting, and local instability under load. Multiple adjacent reinforcing plates 202 serve as support units, and longitudinal main beams 204 are installed parallel to each other along the circumference, firmly connecting the longitudinal main beams 204 to the reinforcing plates 202. This creates a continuous main load-bearing component along the roadbed extension direction, bearing and distributing longitudinal tensile and compressive stresses. Then, in the longitudinal main... An arc-shaped secondary beam 205, bent along the curvature of the arch, is installed on beam 204, so that the longitudinal main beam 204 and the arc-shaped secondary beam 205 are arranged in a spatially orthogonal intersection, together forming a hollow arched grid base. Utilizing the unique stress characteristics of the arch structure, concentrated loads are quickly converted into axial pressure and diffused in all directions, significantly improving the overall compressive strength, impact resistance, and settlement resistance of the roadbed. At the same time, the hollow structure can reduce self-weight and enhance soil interlocking and drainage. Meanwhile, diagonal main beams 206 are installed on both sides of the longitudinal main beam 204, and arch head connecting columns 207 are connected to the ends of the diagonal main beams 206. Transverse connecting rods 2 are erected between the arch head connecting columns 207. 08. The arch head connecting column 207, the transverse connecting rod 208 and the inclined main beam 206 are combined to form a top limiting frame, which provides transverse constraint and limitation to the top of the arched space frame base, counteracts the outward expansion force and lateral displacement generated under load, maintains the overall geometric stability of the skeleton, and prevents the space frame structure from expanding outward and deforming. Then, connecting beams 209 and connecting rods 216 are installed between multiple sets of reinforcing plates 202, connecting all columns 201 laterally in a continuous and integral load-bearing skeleton, so that each column and each space frame unit can bear the force together, avoid stress concentration and local damage caused by the independent bearing of a single component, and comprehensively improve the overall stiffness and compressive bearing capacity of the roadbed.Next, install the drainage component 3. A groove 301 is cut at the center of the inner wall of the column 201. The pipe 304 is embedded and fixed inside the groove 301. A horizontal support arm 302 is connected to the outside of the column 201. A pad 305 is installed at one end of the inner wall of the pipe 304. The cap 306 is placed against the pad 305 and mates with the pipe 304. A round cap 307 is fitted onto the end of the pipe 304. An inclined column 308 and a vertical column 309 are installed on the outside of the round cap 307. The inclined column 308... The vertical column 309 is fixed to the end of the column body 201 to ensure that the drainage pipe 304 is stable and does not shift. At the same time, a drainage arc pipe 310 is laid inside the subbase 401 near the base layer 402 to form a three-dimensional drainage system for the roadbed. After the installation of the compressive strength and drainage system is completed, the reinforcement components 4 are laid from bottom to top on the top of the roadbed body 1. First, a subbase 401 composed of hard crushed stone is laid and compacted. The second intercepting plate 212 is embedded inside the subbase 401 near the roadbed body 1. A base course 402, composed of a mixture of fine sand and gravel, is laid on top of the base course 401. A first intercepting plate 210 is embedded inside the base course 402 near the subbase 401. A third intercepting plate 214 is embedded inside the roadbed body 1 and between the columns 201. These three layers of intercepting plates intercept soil particles and prevent roadbed erosion through their circular groove structure. Finally, an asphalt concrete surface layer 403 is laid on top of the base course 402 and compacted. After the road is put into use, rainwater flows down through the gaps in the surface layer 403. The drainage system, in conjunction with the drainage arc pipe 310, quickly discharges accumulated water to the outside of the roadbed, preventing soil softening and settlement. Vehicle loads are sequentially transferred through the surface layer 403, base layer 402, and subbase layer 401 to the compression-resistant component 2. Vertical support is provided by the column 201, horizontal dispersion by the arched grid base, and deformation restraint by the top limiting frame, evenly distributing the load across the entire roadbed structure 1. Simultaneously, the multi-layered intercepting plates and the overall framework constrain soil displacement, maintaining long-term stability of the roadbed structure, preventing collapse, cracking, and settlement.
