Road gantry structure product case
Project Background
In order to improve traffic management efficiency and road safety, the Mongolian Transport Administration decided to install a number of gantries on major roads to hang traffic signs, monitoring equipment and electronic information screens. These gantries are designed with high-strength steel structures to ensure their stability and durability in adverse weather conditions.
Project Overview
● Project Name: Gantry Installation Project for Main Roads in Mongolia
● Construction site: Main road in Mongolia
● General Contractor: Arsh Technology LLC
● Construction Company: Arsh Technology LLC
Design and Construction
Design Phase
1. Design standards: Comply with relevant national and industry standards, including "Highway Traffic Signs and Markings", "Urban Road Design Code", "Steel Structure Design Code", etc.
2. Structural design:
● Main structure: Hot-rolled steel pipes are used as main beams and columns to ensure the stability and strength of the overall structure.
● Secondary structure: Cold-bent steel tubes and steel plates are used as secondary beams and supports to enhance the rigidity and stability of the structure.
● Connection method: high-strength bolts and welding are used, and key nodes are reinforced.
3. Protection design: Windproof, rainproof and anti-corrosion measures are designed. The external structure is sprayed with anti-corrosion paint and hot-dip galvanized to improve durability.
Construction Phase
1. Raw material procurement
All raw materials are purchased from well-known steel mills to ensure that the material quality meets national standards. After the materials enter the factory, they are strictly inspected to ensure that there are no defects or rust.
2. Processing technology
The processing of the gantry mainly includes cutting, welding, drilling and surface treatment. CNC cutting equipment is used to ensure accurate dimensions; in the welding process, automatic welding robots are used to ensure uniform and firm welds; in the drilling process, high-precision drilling equipment is used to ensure accurate hole positions; finally, hot-dip galvanizing is performed to improve corrosion resistance.
3. On - site installation
oFoundation treatment: reinforce the foundation, dig the foundation pit, pour the concrete foundation, and embed the foundation bolts.
● Column installation: Transport the gantry columns to the site, use lifting equipment to erect the columns and fix them on the foundation bolts to ensure verticality and stability.
● Main beam installation: transport the main beam to the site, use lifting equipment to lift the main beam and fix it on the column, ensuring the levelness and firm connection.
● Secondary structure installation: Install secondary beams and supporting structures to ensure the stability and safety of the overall structure.
● Node reinforcement: Reinforce all connection nodes to ensure the firmness of bolts and welding parts.
● Protective construction: After the structure is installed, the anti-corrosion coating is applied to ensure the protective effect.
Project Outcomes
1. Structural stability: The gantry structure is reasonably designed and has excellent wind and rain resistance, ensuring stability and safety under various severe weather conditions.
2. Construction efficiency: Through meticulous on-site installation steps and a professional construction team, the gantry is installed quickly and efficiently, reducing the impact on road traffic.
3. Protection effect: High-standard anti-corrosion design and construction ensure the long-term service life of the gantry and reduce maintenance costs.
4. Economic benefits: Compared with traditional structures, the gantry structure has a higher cost-effectiveness, reduces maintenance costs and improves economic benefits.
Product delivery and customer feedback
After the gantry was completed and passed strict quality inspection, it was delivered to the customer on time. The customer spoke highly of the product quality and trial installation effect, believing that it not only met the design requirements but also had good durability and aesthetics. The customer said that he would continue to choose our company's products in other traffic management projects in the future.
In conclusion, In this road gantry project, through reasonable design, high-quality materials and strict quality control, the gantry not only ensures the stable suspension of traffic management equipment, but also greatly improves construction efficiency and safety. Through the factory trial installation link, potential problems were discovered and solved in advance, ensuring the smooth progress of on-site installation. In the future, as the demand for urban traffic management continues to grow, the gantry will continue to play an important role in the construction of transportation facilities.
The successful implementation of this project not only provides strong support for urban traffic management, but also establishes a good reputation and image for the company in the field of transportation infrastructure construction.
