About the Hashtgerd Dolphin Tunnel Project
Erfan Sanat Isfahan company has implemented the Dolphin Tunnel project in the city of Hashtgerd. This project was designed and implemented with the aim of creating a safe and functional space for pedestrians and improving the visual appeal of the urban environment. Using domestically produced raw materials, advanced lighting, and durable metal structures, this project offers an innovative solution for urban spaces. In the following, the technical details of the project are described to familiarize you with its features and specifications.
Features of Needle String Lights
Technical Specifications of the String Lights
The needle string lights form the main part of the lighting for the Dolphin Tunnel project. These strings, with a length of 1026 meters, are designed to use DC power to minimize energy consumption. Erfan Sanat company has produced these string lights, and they meet high quality standards. The 220-volt input voltage is intended for compatibility with the city’s power system, and no additional equipment is needed for voltage regulation.
1*0.5 flexible wires with a double-layer PVC sheath have been used, which are resistant to sunlight, risk of electric shock, and fire. This sheath ensures the durability and safety of the string lights in various weather conditions. Every 2 meters of these string lights include 20 one-watt base-mounted LEDs with an Epistar chip. These LEDs have a long lifespan, and their light (lumen) depreciation after long-term use is very negligible, which indicates the high quality of domestic production.
Color and Lighting
The color of the string lights was chosen to be warm white with a temperature of 2400 to 2700 Kelvin, which creates a warm and pleasant atmosphere for pedestrians. For the lighting, pink was used for the luminous spheres and blue and white colors for the dolphins. This color combination was carefully selected to maintain the project’s visual harmony and create a uniform and attractive effect.
Safety and Modular Design
The IP68 protection rating makes the string lights resistant to water and dust ingress, making them suitable for outdoor use. The modular design of these string lights allows for easy and consecutive connection, which simplifies installation and maintenance. The use of 20075 and waterproof connectors prevents reverse connection and increases system safety. These features make the string lights ideal for large urban projects.
General Details of the Hashtgerd Dolphin Tunnel Project
Collaboration with Hashtgerd Municipality
This project was implemented in collaboration with the Hashtgerd Municipality. The width of the sidewalk is 5 meters and it includes 9 metal pathways that were designed and built based on the submitted plans. These pathways provide a safe space for pedestrian traffic and, with coordinated lighting, add to the beauty of the urban environment.
Project’s Purpose and Application
The purpose of the Dolphin Tunnel project is to create a space where pedestrians can move safely and comfortably. The lighting and structural design are such that, in addition to functionality, they contribute to the city’s visual appeal. This project is an example of Erfan Sanat Isfahan company’s ability to execute high-quality urban projects.
Excavation and Infrastructure
The project’s infrastructure has been carefully designed and executed. This section includes 18 pits with dimensions of 50×50 cm and a depth of 40 cm, intended for the installation of base plates. The base plates are made with dimensions of 30×30 cm and a thickness of 8 mm. Under each base plate, there is a 50×15 cm rectangular structure with 16mm rebar, which is installed with anchor bolts.
The concrete was poured with a grade of 350 to ensure the necessary resistance to pressure and environmental conditions. This concrete grade ensures that the project’s infrastructure will be resistant to weather factors and physical pressures.
Metal Structures of the Hashtgerd Dolphin Tunnel Project
Design of Metal Pathways
The project’s metal structures include 9 pathways, each made with 6×6 box sections with a 2 mm thickness. These box sections have the necessary strength to bear the weight of the string lights and environmental conditions. The bracing is done with 2×2 cm box sections, which connect two pathways together seamlessly.
Dolphin Structures and Luminous Spheres
The dolphin structures are made with 10×2 box sections. In the middle section of these structures, a metal mesh is used to hold the needle string lights, which contributes to the structure’s strength. In the center of each structure, there are luminous spheres with a diameter of 20 cm, which are formed from identical metal frames. These spheres are illuminated with pink light and are the visual focal point of the project.
Coating and Durability of the Structures
All structures are coated with white electrostatic paint, which increases their durability against rust and corrosion. This coating also contributes to the project’s visual harmony and gives the structures a clean and professional appearance.
Neon Flex Strips
Technical Specifications
The dolphin structures are made with 10×2 box sections. In the middle section of these structures, a metal mesh is used to hold the needle string lights, which contributes to the structure’s strength. In the center of each structure, there are luminous spheres with a diameter of 20 cm, which are formed from identical metal frames. These spheres are illuminated with pink light and are the visual focal point of the project.
Application in Lighting
The neon flex strips complement the needle string lights and help create uniform lighting throughout the entire pathway. These strips are produced with high quality and, due to their resistance to weather conditions, are suitable for outdoor use.
Electrical and Control System
Power Control Box
The project’s power control box, with dimensions of 20x30x20 cm, is made of metal with an “Indy” coating. The equipment inside the box includes the following:
-
10-amp single-phase miniature circuit breaker
-
25-amp contactor
-
Contactor protector
-
Timer and astronomical clock
-
Residual-current device
-
Earthing equipment
Equipment Installation and Safety
The equipment is mounted on a galvanized tray with a rail for easy access and maintenance. The earthing system has been implemented separately for each structure, and authorized powders have been used for grounding. This system ensures the project’s safety against electrical hazards.
Commitment to Standards
Erfan Sanat Isfahan company, as the project implementer, holds a production standard certificate, a safety certificate, and a contractor qualification. The relevant operating license is also held by the company. These certificates demonstrate the company’s commitment to adhering to quality and safety standards in project execution.
Conclusion
The Dolphin Tunnel project, using domestically produced raw materials, precise design, and professional execution, has created a functional and beautiful space in the city of Hashtgerd. The needle string lights and neon flex strips, metal structures, luminous spheres, and safe electrical system have all been carefully designed and implemented to meet the project’s needs.
