Description

Technical Field

[0001] This utility model relates to the field of municipal road and bridge technology, and in particular to a flood control roadbed for roads and bridges. Background Technology

[0002] As the foundation of the pavement, the roadbed is an earthwork structure formed by excavation or filling. It must withstand the static and dynamic loads generated by vehicle traffic and transfer and diffuse these loads deep into the foundation. During highway construction, some sections of the roadbed protrude above the ground, forming slopes. Because the roadbed is composed of loose materials such as soil and rock, its structure is loose. During periods of heavy rainfall, water flowing from the road surface towards the slopes can easily erode the soil and rock structure along the roadbed edges, forming gullies that can lead to collapse and reduce the overall stability of the roadbed.

[0003] For example, a municipal road and bridge flood control subgrade with patent publication number "CN220035080U" increases the subgrade's erosion resistance by setting a water-blocking layer and a water-retaining plate on the subgrade body, with the water-retaining plate having a water-diverting channel. The water-retaining plate is used to withstand the impact of rainwater and stabilize the soil and rock structure, while the water-diverting channel accelerates the water flow and reduces accumulation, and the water-blocking layer reduces seepage.

[0004] However, the fixing method between the water barrier and the roadbed in the above-mentioned patent is relatively rigid. When subjected to continuous water flow or slight ground settlement, stress concentration is likely to occur between the water barrier and the roadbed, which may cause the connection of the water barrier to loosen or even be damaged. Utility Model Content

[0005] The purpose of this utility model is to provide a flood control roadbed for bridges and roads, which solves the problem that the fixing method of the water retainer and the roadbed in the above-mentioned patent is relatively rigid. When subjected to continuous water flow or slight foundation settlement, stress concentration is easily generated between the water retainer and the roadbed, which may lead to loosening or even damage of the connection part of the water retainer.

[0006] To achieve the above objectives, this utility model provides a roadbed for flood control of bridges, including a roadbed body, a reinforcement and anti-scour mechanism provided below the roadbed body, and a water-blocking mechanism provided on one side of the roadbed body. The water-blocking mechanism includes a lower washer, a spring, and an upper washer. The lower washer is installed on one side of the roadbed body, the spring is fixedly connected to one end of the lower washer, and the upper washer is fixedly connected to one end of the spring.

[0007] The roadbed body has an anti-impact base fixedly connected to its lower surface, and a threaded rod is threadedly connected to the inner wall surface of the anti-impact base. A drill bit is fixedly connected to one end of the threaded rod.

[0008] The threaded rod passes through both ends of the anti-impact base, and a rotating block is fixedly connected to the other end of the threaded rod.

[0009] The roadbed has a geotextile layer laid on one side, a waterproof coating on one side, and a water-retaining edge fixedly connected to the upper surface of the roadbed.

[0010] The water-blocking mechanism further includes multiple water-blocking plates. A drainage groove is provided on one side of each water-blocking plate, and filter plates are fixedly connected to both sides of the inner wall of the drainage groove.

[0011] The water baffle has a connecting groove on one side and a connecting block fixedly connected to the other side, with the connecting block slidably connected to the inner wall surface of the connecting groove.

[0012] The water-retaining plate is fixedly connected to a fixing seat on one side, and a bolt is threadedly connected to the other side of the water-retaining plate. The bolt passes through the geotextile layer and is threadedly connected to the roadbed body. The lower shim is placed at the bottom of the inner wall of the fixing seat, and both the lower shim and the upper shim are sleeved on the surface of the bolt.

[0013] This utility model discloses a flood-resistant roadbed for bridges and highways. A water-blocking mechanism consisting of a lower pad, a spring, and an upper pad is installed on one side of the roadbed. The lower pad is installed on one side of the roadbed, and the spring connects the lower and upper pads. Utilizing the elasticity of the spring, the impact force of water flow on the water-blocking mechanism and the stress caused by foundation settlement can be buffered, preventing rigid stress concentration between the water-blocking plate and the roadbed, and reducing the possibility of loosening or damage at the connection points. Simultaneously, the reinforcement and anti-scour mechanism below the roadbed enhances the protection of the roadbed base, thereby improving the overall flood-resistant stability of the roadbed.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5 A flood-resistant roadbed for bridges includes a roadbed body 1, a reinforced anti-scour mechanism 2 installed below the roadbed body 1, and a water-blocking mechanism 3 installed on one side of the roadbed body 1. The water-blocking mechanism 3 includes a lower washer 311, a spring 312, and an upper washer 313. The lower washer 311 is installed on one side of the roadbed body 1, the spring 312 is fixedly connected to one end of the lower washer 311, and the upper washer 313 is fixedly connected to one end of the spring 312. The water-blocking mechanism 3, through the combined structure of the lower washer 311, the spring 312, and the upper washer 313, utilizes the elastic characteristics of the spring 312 to convert the rigid force generated by the water flow impacting the water-blocking plate 304 into an elastic buffering force, reducing the stress concentration at the connection between the water-blocking plate 304 and the roadbed body 1. When the lower washer 311 and the upper washer 313 are fixed by bolts 310, the spring 312 is in a compressed state, which can adapt to the small displacement of the roadbed body 1 caused by settlement or temperature changes, preventing the connection structure from loosening, thereby enhancing the stability and durability of the water-blocking mechanism 3.

[0023] Furthermore, an anti-scouring base 201 is fixedly connected to the lower surface of the roadbed 1. A threaded rod 202 is threadedly connected to the inner wall surface of the anti-scouring base 201. A drill bit 203 is fixedly connected to one end of the threaded rod 202. The anti-scouring base 201 provides large-area support for the bottom of the roadbed 1 and disperses the pressure of the roadbed 1 on the ground. By rotating the threaded rod 202, the drill bit 203 is driven into the underground soil through thread transmission, which firmly connects the anti-scouring base 201 to the underground structure, enhances the anti-slip ability and overall stability of the bottom of the roadbed 1, and reduces the settlement or displacement caused by the scouring of the bottom of the roadbed 1 by floods.

[0024] Furthermore, the threaded rod 202 passes through both ends of the anti-impact base 201, and a rotating block 204 is fixedly connected to the other end of the threaded rod 202. The rotating block 204 increases the contact area of ​​the force application point, making it easier for construction personnel to rotate the threaded rod 202 by rotating the rotating block 204, thus reducing the difficulty of operation. The design of the threaded rod 202 passing through the anti-impact base 201 ensures that the drill bit 203 can drill into the ground stably along a straight line, ensuring the connection strength.

[0025] Furthermore, a geotextile layer 301 is laid on one side of the roadbed 1, and a waterproof coating 302 is applied to one side of the geotextile layer 301. A water-retaining edge 303 is fixedly connected to the upper surface of the roadbed 1. The geotextile layer 301 has good permeability and filtration properties, which can prevent soil particles from being lost while allowing water to penetrate, thus protecting the structure of the roadbed 1. The waterproof coating 302 forms a continuous impermeable membrane, which further prevents water from seeping into the interior of the roadbed 1 and avoids the roadbed 1 from softening due to water seepage. The water-retaining edge 303 reduces the direct flow of surface water from the road to the slope of the roadbed 1 through physical blocking, thereby reducing the intensity of the slope being impacted by water flow.

[0026] Furthermore, the water-blocking mechanism 3 also includes multiple water-blocking plates 304. A drainage channel 305 is provided on one side of each water-blocking plate 304. Filter plates 306 are fixedly connected to both sides of the inner wall of the drainage channel 305. Multiple water-blocking plates 304 are spliced ​​together to form a continuous water-blocking barrier, directly bearing the impact of water flow and protecting the slope of the roadbed 1. The drainage channel 305 provides a directional flow channel for water flow, accelerating the water discharge speed and reducing the pressure of accumulated water on the water-blocking plate 304. The filter plates 306 can filter impurities such as stones and branches in the water, preventing the drainage channel 305 from being blocked and ensuring smooth drainage.

[0027] Furthermore, a connecting groove 307 is provided on one side of the baffle plate 304, and a connecting block 308 is fixedly connected to the other side of the baffle plate 304. The connecting block 308 is slidably connected to the inner wall surface of the connecting groove 307. Adjacent baffle plates 304 can be quickly spliced ​​by sliding into the connecting groove 307 through the connecting block 308. The cooperation between the connecting block 308 and the connecting groove 307 restricts the relative displacement of adjacent baffle plates 304 in the horizontal and vertical directions. This splicing method facilitates on-site installation and subsequent maintenance. When a single baffle plate 304 is damaged, it can be replaced individually, reducing maintenance costs.

[0028] Furthermore, a fixing seat 309 is fixedly connected to one side of the water-retaining plate 304, and a bolt 310 is threadedly connected to one side of the water-retaining plate 304. The bolt 310 penetrates the geotextile layer 301 and is threadedly connected to the roadbed body 1. A lower washer 311 is placed at the bottom of the inner wall of the fixing seat 309. Both the lower washer 311 and the upper washer 313 are fitted onto the surface of the bolt 310. The bolt 310 fixes the water-retaining plate 304, the geotextile layer 301, and the roadbed body 1 as a whole through threaded connection. 309 provides a stable support point for bolt 310; the lower washer 311 and the upper washer 313 increase the contact area between bolt 310 and water baffle 304, preventing damage to water baffle 304 when bolt 310 is tightened; spring 312 is in a compressed state after bolt 310 is tightened. When water baffle 304 is impacted or the roadbed body 1 is slightly subsided, spring 312 can absorb energy and buffer stress through elastic deformation, reducing the risk of damage to bolt 310 and water baffle 304.

[0029] The complete work process is as follows: First, the foundation surface of the roadbed 1 is leveled. The erosion control base 201 is then fixedly connected to the lower surface of the roadbed 1 using embedded parts, ensuring a firm connection between the erosion control base 201 and the roadbed 1. Next, workers rotate the rotating block 204, causing the threaded rod 202 to rotate within the erosion control base 201. Utilizing the threaded transmission principle, the drill bit 203 at one end of the threaded rod 202 slowly drills into the underground soil until the threaded rod 202 forms a stable connection with the underground structure, thereby enhancing the anti-slip capability of the erosion control base 201. Then, a geotextile layer 301 is evenly laid on the slope surface of the roadbed 1. During laying, it is ensured that the geotextile layer 301 adheres tightly to the surface of the roadbed 1 without wrinkles or voids. Finally, a waterproof coating 302 is evenly applied to the side of the geotextile layer 301 away from the roadbed 1. After the waterproof coating 302 dries and cures, an effective seepage barrier is formed. Simultaneously, a water-retaining edge 303 is poured along its length on the upper surface of the roadbed 1, ensuring a firm connection between the water-retaining edge 303 and the roadbed 1. Then, multiple water-retaining plates 304 are spliced ​​together. Specifically, the connecting block 308 on one water-retaining plate 304 is aligned with the connecting groove 307 on the adjacent water-retaining plate 304, and the water-retaining plate 304 is slowly pushed so that the connecting block 308 slides into the connecting groove 307 until the adjacent water-retaining plates 304 are tightly fitted together. After splicing, the water-retaining plates 304 are placed on the geotextile layer 301 on one side of the roadbed 1, ensuring that the fixing seat 309 on the water-retaining plate 304 corresponds to the pre-set bolt 310 installation position. Subsequently, a lower washer 311 is placed at the bottom of the inner wall of the fixing seat 309, a spring 312 is placed above the lower washer 311, and an upper washer 313 is placed above the spring 312. Then, bolts 310 are passed through the upper washer 313, spring 312, lower washer 311, water-retaining plate 304, and geotextile layer 301 in sequence and screwed into the roadbed body 1. Tightening the bolts 310 compresses the spring 312, thereby firmly fixing the water-retaining plate 304 to the roadbed body 1. When encountering rainfall or floods, the water-retaining edge 303 on the upper surface of the roadbed body 1 first blocks the water accumulation on the road surface, reducing the direct flow of water to the slope. For water flowing over the water-retaining edge 303 to the slope, the water-retaining plate 304 forms a barrier, directly bearing the impact force of the water flow and protecting the slope structure of the roadbed body 1. After the water flow impacts the baffle plate 304, some of the water is discharged through the drainage channel 305 on the baffle plate 304. During the drainage process, the filter plate 306 inside the drainage channel 305 filters impurities in the water flow to prevent impurities from clogging the drainage channel 305 and ensure smooth drainage. During the process of the water flow impacting the baffle plate 304, the impact force on the baffle plate 304 is transmitted to the spring 312 through the bolt 310. The spring 312 absorbs part of the impact force through elastic deformation, playing a buffering role and reducing stress concentration at the connection between the baffle plate 304 and the roadbed body 1, thus preventing the connection structure from loosening or being damaged.Meanwhile, the geotextile layer 301 and the waterproof coating 302 work together to prevent water from seeping into the interior of the roadbed 1, thus avoiding softening of the roadbed 1 due to water seepage. The reinforcement and erosion protection mechanism 2 below the roadbed 1 effectively resists the erosion of the roadbed base by floods, preventing settlement or displacement at the bottom of the roadbed and ensuring the stability of the entire roadbed structure.
