Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a prefabricated emergency protection structure for road slopes. Background Technology

[0002] A slope is a sloping surface with a certain gradient created on both sides of a roadbed to ensure its stability. Based on its formation, it can be classified into artificial slopes and natural slopes. Slope protection refers to the reinforcement measures taken to prevent surface water runoff from eroding road slopes or sloping terrain. Reinforcement measures include gravel slope protection, retaining wall slope protection, and vegetation slope protection.

[0003] Currently, the main slope protection measures typically involve covering and wrapping various flexible nets, primarily steel wire rope mesh, onto the slope or rock to restrict weathering and erosion of the slope's rock and soil, as well as preventing rockfalls (reinforcement), or controlling the movement of falling rocks within a certain range (containment). However, after installation, these protective net structures often only cover the slope itself, while simple guardrails are usually installed along the roadside. On the one hand, the guardrails are simple in structure and offer less than ideal protection, potentially creating psychological stress for drivers. On the other hand, while some steel wire mesh structures with sufficient strength can withstand significant impact, their cushioning effect is often inadequate, leading to secondary impacts from falling rocks and increasing safety hazards. Furthermore, it is inconvenient to perform targeted maintenance on deformations or cracks in specific sections of the mesh over a given span, resulting in uneven protection. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated emergency protection structure for roadside slopes. This protection structure is easy to install and perform targeted maintenance, while providing high protection for the road surface. It reduces the damage to the road surface caused by the large amplitude of rockfall and secondary impacts, and can effectively reduce the unnecessary psychological burden on drivers of passing vehicles, thereby improving vehicle safety during driving.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A prefabricated emergency protection structure for road slopes includes protective components installed on the road surface at the bottom of the slope on both sides of the road. The protective components include multiple sets of fixed rods and multiple sets of connecting parts slidably disposed on them, as well as several sets of bow-shaped plates connected between adjacent fixed rods through the multiple sets of connecting parts. The adjacent connecting parts on the fixed rods are connected by multiple sets of compression springs disposed at corresponding sliding connection points on the fixed rods.

[0007] Preferably, the connector is detachably mounted on the fixing rod via a baffle installed on the top of the fixing rod.

[0008] Preferably, the protective component further includes a fixing base, and the fixing rod is slidably disposed on the fixing base and a locking element is rotatably disposed at the corresponding sliding connection.

[0009] Preferably, the connector includes a first connecting seat slidably disposed on the fixed rod and a second connecting seat slidably disposed on the first connecting seat.

[0010] Preferably, the compression spring is fitted with a suitable telescopic sleeve on its outer side.

[0011] Preferably, the bow-shaped plate can be replaced with a protective net structure.

[0012] Preferably, side ditches are also provided on the bottom of the slopes on both sides of the road, away from the protective components on the road surface.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This utility model relates to a prefabricated emergency protection structure for road slopes. Compared to traditional guardrails or protective nets on both sides of the road, the overall structure of this prefabricated emergency protection structure features a fixed rod and several sets of bow-shaped plates connected by multiple sets of connectors, along with multiple sets of compression springs between adjacent connectors on the fixed rod. This not only provides some protection against falling rocks on the slope, but also, when a rock falls and impacts the bow-shaped plates, due to the structural characteristics of the bow-shaped plates and the multiple sets of compression springs between adjacent connectors on the fixed rod, the bow-shaped plates at the impact position can deform appropriately upon impact, causing the connectors to move up and down along the grooves of the fixed rod. The sliding process effectively buffers and reduces the impact force of falling rocks upon impact, minimizing the large amplitude of rock movement and secondary impacts that could cause unnecessary or secondary damage to the protective components and even the road surface. This improves the protective effect and stability of the components. Furthermore, the structure of this protective component enhances driver safety, reduces potential hazards, and improves vehicle safety during driving. It also provides cushioning in the event of a collision between a vehicle and the protective components on either side of the road, minimizing further injury to the vehicle and driver. Additionally, the modular design of multiple fixing rods, connectors, and arched plates allows for easy installation, disassembly, and routine inspection and maintenance for various environments and requirements. It also allows for the removal, adjustment, and replacement of arched plates that may deform or crack during operation, improving operational convenience and efficiency. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figure 1-2 This embodiment relates to a prefabricated emergency protection structure for a roadside slope 100, including a protection component 1 installed on the road surface 101 at the bottom of the slope 100 on both sides of the road. The protection component 1 includes multiple sets of fixed rods 11 and multiple sets of connecting parts 12 slidably disposed on them, as well as several sets of bow-shaped plates 13 connected between adjacent fixed rods 11 by the multiple sets of connecting parts 12. The adjacent connecting parts 12 on the fixed rods 11 are connected by multiple sets of compression springs 14 disposed at corresponding sliding connection points on the fixed rods 11.

[0022] Specifically in this embodiment, such as Figure 1 The diagram shows the overall structure and corresponding installation positions of the protective components 1 on the roadside slopes 100 and their bottom surface 101. The protective components 1 can be installed on the roadside surface 101 on both sides of the road using multiple sets of fixing rods 11. The specific installation position can be adjusted according to the specific installation environment and the specific slope of the corresponding slope 100, by adjusting the distance between the protective components 1 on the roadside surface 101 and the bottom of the slope 100. During installation, refer to... Figure 2The connection method between the connector 12 and the bow plate 13 shown is such that multiple bow plates 13 provided between adjacent fixed rods 11 can be staggered by the connector 12. Specifically, the adapter structure of the connector 12 can be provided with an adapter groove 111 at the corresponding position of the fixed rod 11, and the groove 111 is built into multiple sets of compression springs 14 connected between adjacent connectors 12 to realize the up and down sliding process of multiple sets of connectors 12 on the fixed rod 11. At the same time, with the several mounting holes provided on the connector 12 and the multiple sets of bolt connectors 10 passing through the mounting holes, the detachable connection process of several sets of arc plates between multiple sets of connectors 12 can be realized. The bow plate 13 can be made of a plate structure with a certain elastic modulus in the early stage of manufacturing, and the length and thickness can be selected according to the installation environment and protection requirements while having a certain deformation capacity. This allows for the assembly process of the protective component 1 with a certain span along the road surface 101 on both sides of the road to be coordinated with the distance adjustment between multiple sets of fixed rods 11. Compared to traditional guardrails or protective nets on both sides of the road 101, the overall structure of this prefabricated emergency protection structure for road slope 100 features a fixed rod 11 and several sets of bow-shaped plates 13 connected by multiple sets of connectors 12, as well as multiple sets of compression springs 14 between adjacent connectors 12 on the fixed rod 11. This structure not only provides some protection against falling rocks on the slope 100, but also, due to the structural characteristics of the bow-shaped plates 13 and the multiple sets of compression springs 14 between adjacent connectors 12 on the fixed rod 11, when a rock falls and impacts the bow-shaped plates 13, the bow-shaped plates 13 at the impact position can deform appropriately and correspondingly drive the connectors 12 along the sliding grooves 111 of the fixed rod 11. The sliding motion of the rock can buffer and dampen the impact force generated by the falling rock at the moment of impact, effectively reducing the large jumping amplitude and secondary impact of the falling rock, thus reducing unnecessary or secondary damage to the protective component 1 and even the road surface 101. This improves the protective effect and stability of the protective component 1. In addition, the structure of this protective component 1 can also appropriately improve the driver's sense of security when driving over it, reduce unnecessary safety hazards, and improve the safety of the vehicle during driving. Furthermore, when a vehicle on the road surface 101 collides with the protective components 1 on both sides of the road surface 101 due to abnormal conditions, it can also play a certain buffering role, reducing further damage to the vehicle and the driver.Furthermore, the modular structure of multiple fixed rods 11, connecting parts 12, and bow-shaped plates 13 in this type of protective component 1 facilitates installation, disassembly, daily inspection, and maintenance for different installation environments and requirements. It also allows for the removal, adjustment, and replacement of the corresponding bow-shaped plates 13 in conjunction with the connecting parts 12 to address any abnormalities such as deformation or cracking that occur during the protective process, thus improving operational convenience and efficiency.

[0023] The connecting member 12 is detachably mounted on the fixing rod 11 via a baffle 112 installed on the top of the fixing rod 11, as detailed in the following document. Figure 3 As shown, the baffle 112 is detachably mounted on the top of the fixed rod 11 via bolt connectors 10. This allows for the detachable installation of the baffle 112. The connector 12 and compression spring 14 sliding in the groove 111 on the fixed rod 11 can slide out for detachable installation. The connector 12 mounted on the fixed rod 11 with this detachable structure and the multiple sets of compression springs 14 connected between adjacent connectors 12 can be installed in a corresponding number of sets of connectors 12 and compression springs 14 according to the fitting structure of the bow plate 13 and the installation height of the fixed rod 11 on the corresponding road surface 101. This further improves the structural detachability and usage flexibility of this protective component 1.

[0024] The protective component 1 further includes a fixing base 15, and the fixing rod 11 is slidably disposed on the fixing base 15, with a locking member 114 rotatably disposed at the corresponding sliding connection. Figure 2 or Figure 3As can be seen, the protective component 1 can be installed and fixed on the road surface 101 at corresponding positions through multiple sets of fixing rods 11 connected to the bottom of fixing seats 15 and multiple sets of bolts on the fixing seats 15. The fixing rods 11 are connected to the second sliding groove 113 at their bottom and the corresponding positions of the fixing seats 15 are connected to the matching slide rails 151. With the help of the locking parts 114 rotatably set at the corresponding sliding connection, the multiple sets of fixing rods 11 on the fixing seats 15 can be adjusted to different positions along the slide rails 151 on the fixing seats 15 and locked at corresponding positions. Specifically, the locking parts 114 can adopt the structure of conventional bolt connectors 10, which are used in conjunction with the fixing rods. The matching threaded hole provided at the corresponding sliding connection between the locking member 114 and the fixed base 15 enables the locking and unlocking movement of the locking member 114 on the fixed rod 11. The protective component 1 installed using this method has high structural adjustability. The addition of the fixed base 15 can further improve the installation efficiency of this protective component 1. During the installation process, the distance between multiple sets of fixed rods 11 can be easily adjusted. The number of fixed rods 11 on the fixed base 15 can be adjusted according to the specific installation environment and installation requirements. In this way, the connection stability and function of the bow plate 13 can be further improved by adding a certain number of fixed rods 11.

[0025] The connector 12 includes a first connecting seat 121 slidably disposed on the fixed rod 11 and a second connecting seat 122 slidably disposed on the first connecting seat 121. See details below. Figure 4 As shown, the connector 12 with this structure can slide up and down along the corresponding groove 111 of the fixing rod 11 through the structure of the first connecting seat 121. At the same time, during the process of locking the bow plate 13 through the mounting hole of the bolt connector 10, the second connecting seat 122 can slide along the third groove 1211 provided on the first connecting seat 121, thereby further improving the connection stability of the connector 12. It can also lock during the sliding process according to the thickness of the bow plate 13, thus improving its applicability.

[0026] The compression spring 14 is also fitted with a suitable telescopic sleeve. Specifically, during the installation process, the telescopic sleeve can be added to the outside of the compression spring 14 without affecting its normal extension and retraction. The telescopic sleeve can be set with a bellows structure, which can provide a certain protective effect for the compression spring 14 and further improve the effect and stability of the compression spring 14.

[0027] The bow-shaped plate 13 can be replaced with a protective net structure. The bow-shaped plate 13 can be replaced with a protective net structure according to different usage requirements to suit different installation environments and installation requirements, which facilitates installation and disassembly while further improving the structural adaptability and versatility of this protective component 1.

[0028] Side ditches 102 are also provided on both sides of the road along the bottom of the slope 100 away from the protective component 1 on the road surface 101, from... Figure 1 As can be seen, the side ditch 102 located at the bottom of the slope 100 between the protective components 1 can play a certain drainage role. At the same time, it can also intercept the falling rocks on the slope 100 after they are intercepted by the protective components 1 and fall into the side ditch 102 for collection, which facilitates subsequent treatment and improves the protection effect on the slope 100 and the road surface 101.

[0029] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
