Description

Technical Field

[0001] This utility model relates to intelligent anti-theft covers for highway tunnels, and more particularly to intelligent anti-theft RPC tunnel cable trough covers. Background Technology

[0002] Reactive Powder Concrete (RPC) is a novel, ultra-high strength, high-durability cement-based composite material developed by Bouygues of France in 1993. The following is an analysis of its core characteristics and applications:

[0003] Basic definition and composition

[0004] Material composition

[0005] RPC is composed of cement, ultrafine active powder (quartz sand, silica fume), mineral admixtures, steel fibers and superplasticizers. Through optimized particle size distribution (particle size <600μm) and high-temperature curing process, an ultra-high density microstructure is formed.

[0006] Technical Principles

[0007] By removing coarse aggregate, reducing porosity, incorporating steel fibers to enhance toughness, and utilizing active powders such as silica fume to promote hydration reactions, a leapfrog improvement in material performance can be achieved.

[0008] Core performance indicators

[0009] Mechanical properties

[0010] Compressive strength: 200~800MPa (divided into RPC200 and RPC800 grades);

[0011] Flexural strength: 20~40MPa, fracture energy up to 4×10 4 J / m², close to the ductility of steel;

[0012] Elastic modulus: 50~60GPa, much higher than that of ordinary concrete.

[0013] Durability

[0014] It has extremely strong impermeability, with a chloride ion permeability coefficient less than 1 / 100 of that of ordinary concrete;

[0015] It can withstand more than 1,000 freeze-thaw cycles, has excellent resistance to carbonization, and has a service life of more than 100 years.

[0016] Volume stability

[0017] With low autogenous shrinkage (approximately 200~400με) and a creep coefficient only 1 / 3 that of ordinary concrete, it is suitable for precision structures.

[0018] Repair and reinforcement

[0019] It can be used as an alternative to steel for bridge repairs, combining high strength and durability while reducing maintenance costs.

[0020] Advantages

[0021] Lightweight structure (weighing only 40% of ordinary concrete under the same load-bearing capacity);

[0022] Low life-cycle cost, reducing resource consumption and carbon emissions.

[0023] As a crucial component of transportation infrastructure, highway tunnels rely heavily on their internal power lines for normal operation. Typically, these power lines are strategically placed in dedicated cable trays. These trays act as the tunnel's "power hub," bearing the brunt of the entire tunnel's power system. They connect to and supply power to numerous devices, such as tunnel lighting, which illuminates the path for vehicles and pedestrians, preventing accidents caused by darkness; ventilation systems continuously supply fresh air and expel harmful gases like vehicle exhaust, ensuring air quality; and monitoring equipment constantly monitors traffic conditions and equipment operation, enabling timely detection and handling of emergencies. In short, the dedicated cable trays housing the power lines are fundamental to ensuring the proper functioning of tunnel lighting, ventilation, monitoring, and other related equipment.

[0024] However, in actual tunnel operation, cable trough covers frequently encounter various problems. Among these, damage and theft are particularly prominent, especially in municipal highway tunnels. There are many reasons for cover damage, such as frequent vehicle traffic and impacts from heavy objects; theft is mainly due to unscrupulous individuals selling the covers as scrap for personal gain. Once a cable trough cover is damaged or stolen, the cables that were originally protected within the trough are directly exposed. This not only makes the cables more susceptible to damage from external factors, such as damp environments potentially damaging the cable insulation and causing short circuits, but also poses a serious threat to the safety of vehicles and pedestrians within the tunnel. For example, a damaged cover may cause a passing vehicle's tire to sink into it, leading to loss of control; pedestrians may also slip and fall, sustaining injuries, if they accidentally step on a damaged area.

[0025] To ensure cable trench covers function effectively in tunnel environments, they must possess a range of performance characteristics. First, strength and load-bearing capacity are fundamental requirements. Due to frequent vehicle traffic within tunnels, the covers must withstand the weight of vehicles and the impacts generated during travel. Sufficient strength and load-bearing capacity are essential to prevent damage over long-term use. Second, flame retardancy is crucial. The relatively enclosed space within tunnels means that in the event of a fire, flame-retardant covers can effectively prevent the spread of fire, buying time for evacuation and firefighting. Third, safety is paramount for personnel and equipment safety. The cover surface should have anti-slip properties to prevent pedestrians from slipping and vehicles from losing control; simultaneously, its structural design must be reasonable, avoiding sharp edges to prevent injury. Finally, wear resistance and corrosion resistance are also critical. The tunnel environment is complex, with vehicle traffic generating friction; therefore, the covers must possess good wear resistance to ensure their lifespan. Furthermore, tunnels may contain moisture, acids, alkalis, and other corrosive substances; corrosion-resistant covers can effectively resist these substances, extending their service life.

[0026] Currently, cable trough covers in highway tunnels are mainly designed with two types of covers: concrete covers and cast iron covers. However, both types of covers have their own drawbacks. While concrete covers possess a certain strength, their weight is significant, requiring substantial manpower and resources for installation, and the installation process is also quite difficult. Furthermore, their bulky nature makes maintenance and replacement inconvenient, necessitating the use of large machinery and increasing costs. Cast iron covers, while possessing a certain strength and good electrical conductivity, are easily targeted for theft. In addition, cast iron covers have poor corrosion resistance and are prone to rusting and corrosion in the humid, acidic, and alkaline environments of tunnels, thus reducing their service life. Moreover, existing cast iron covers often lack anti-theft design considerations and effective anti-theft measures, further increasing the risk of theft.

[0058] This patent provides multiple parallel solutions; the different descriptions represent improved or parallel solutions based on a basic solution.

Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0059] Example 1: Referring to all the attached drawings; Intelligent anti-theft RPC tunnel cable trough cover, characterized in that,

[0060] The anti-theft RPC tunnel cable trough cover 3 is arranged on the tunnel cable trough on the side of tunnel 1;

[0061] The main material of the anti-theft RPC tunnel cable trough cover plate 3 is RPC concrete;

[0062] The RPC tunnel cable trough cover plate comprises multiple cover plate units 31;

[0063] A space 34 is arranged on the cover plate unit 31, and a positioning device 36 and a lithium battery 35 capable of supplying power to the positioning device 36 are arranged in the space 34. The space 34 includes the cover plate. The substantial technical effect and implementation process of the technical solution, i.e., its basic function, are as follows:

[0064] This new type of intelligent anti-theft RPC tunnel cable trough cover is an optimized design based on the traditional cable trough cover. It combines the functions of light weight, beautiful appearance, high strength, anti-theft durability, and simple installation. In addition, it can provide the real-time operational status of the cable trough through the positioning system, which facilitates intelligent operation and monitoring of the tunnel.

[0065] The purpose of this utility model is to provide a novel intelligent anti-theft RPC tunnel cable trough cover for highway tunnels. Compared with traditional covers, this intelligent cover more effectively solves problems related to anti-theft, high strength, lightweight, and wear resistance. It can also provide real-time feedback on the cable trough's usage status, facilitating maintenance and repair. It is reasonable, economical, and highly operable.

[0066] To achieve the above objectives, the technical solution adopted in this utility model design is as follows: an intelligent anti-theft RPC tunnel cable trough cover plate, which uses RPC material to prefabricate the cable trough cover plate. The construction of the secondary lining should take into account the construction of the cable trough. The formwork and construction of the cable trough should be planned in advance by reserving, embedding or constructing simultaneously to avoid the inability to support the formwork in the later construction.

[0067] RPC concrete uses fine sand as aggregate, incorporating a large amount of mineral admixtures such as silica fume, high-efficiency water-reducing agents, and fine steel fibers. This significantly strengthens weak interfaces, resulting in a high-strength, high-toughness, and low-porosity concrete material. Compared to conventional concrete, it removes coarse aggregate (gravel) and is primarily made of cement, active admixtures (fly ash, silica fume, slag powder, etc.), fine aggregate, and high-efficiency water-reducing agents through steam curing (autoclaving). It possesses excellent properties such as ultra-high strength, high durability, high impact toughness, and good volume stability. Cable trough covers made of RPC material are lightweight, high-strength, and low-cost.

[0068] This cover plate is high-strength and lightweight, meeting the stress and fire resistance requirements of tunnel cable trough covers. It is prefabricated in a standardized manner, making quality control easy and transportation and installation convenient. Furthermore, it can provide real-time operational status of the cable trough through an intelligent positioning system, facilitating intelligent operation and monitoring of the tunnel.

[0069] Especially suitable for highway tunnels, this design allows for real-time maintenance and repair of cable trough covers, ensuring cable safety and greatly improving the intelligent operation level of the tunnel, while being economical and reasonable.

[0070] The adoption of this intelligent anti-theft RPC tunnel cable trough cover plate solves the problem of anti-theft of cable trough covers in tunnels, and enables rapid maintenance and repair of cable trough covers. This prevents damage to tunnel cables and avoids affecting the safety of vehicles and pedestrians in the tunnel.

[0071] Example 2: As a further improvement, parallel, or optional independent solution, the RPC concrete side includes a plug-in structure 32, which can lock the cable trough cover, serving as an anti-theft measure. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: In essence, Example 1 already has a certain anti-theft capability because it includes a positioning system that enables remote tracking.

[0072] Example 3: As a further improvement, parallel, or optional independent solution, a warning device 37 is also arranged in space 34, and a lithium battery 35 can power the warning device 37. The substantive technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: the warning device can be an audible and visual alarm system, or a remote alarm and / or an on-site alarm.

[0073] Example 4: As a further improvement, parallel solution, or optional independent solution, both the early warning device 37 and the positioning device 36 are connected to the Internet of Things (IoT); they are connected to the operation monitoring platform via the IoT. The substantive technical effects and implementation process of this technical solution, i.e., its basic functions, are as follows: thus, comprehensive intelligent control can be achieved.

[0074] Example 5: As a further improvement, parallel solution, or optional independent solution, the positioning device 36 is an intelligent positioning display device.

[0075] Example 6: As a further improvement, parallel solution, or optional independent solution, space 34 includes an openable outer cover, which allows for the replacement of the internal lithium battery 35. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: Preferably, the outer cover can be opened with a key. A dedicated key is preferred.

[0076] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0077] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.

[0078] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0079] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
