5G tower cranes, smart bulldozers, welding chips... Shandong's major project construction becomes "smart"
The projects using 5G tower cranes are not limited to Jinan Metro Line 7. At the construction site of Shandong Energy Group Jinan International Trade Industrial Park, the first construction project in Jinan to use 5G tower cranes, tower crane operators do not need to climb onto the tower cranes for high-altitude operations. Instead, they sit in front of the operating chair in the construction site operation room, facing multiple monitoring screens, and remotely control multiple tower cranes on the construction site. Zhang Anxiang, an electromechanical engineer of the Jinan International Trade Industrial Park project of Shandong Energy Group of China Construction Third Engineering Bureau, told reporters that the use of 5G tower cranes can enable a tower crane operator to complete tower crane operations at different times on the ground. Compared with traditional tower cranes that require tower crane operators to perform high-altitude operations, 5G tower cranes greatly save labor costs and increase hoisting efficiency by 15%.

The "old three" construction site leveling has a new smart function
New drivers can do it right the first time without surveyors
At the construction site of the second phase of the Jinan Airport expansion project, bulldozers, graders, and rollers are leveling the airport runway. However, these seemingly ordinary site leveling "old three" also have new intelligence. "You see, we only need the driver to drive the equipment on site, there is no one else around, no surveyor or assistant to direct, and the driver and the equipment do not need to pause and wait for the measurement data to come out before working back and forth." The relevant person in charge of Shantui Co., Ltd., the manufacturer of the equipment, introduced that these equipment are the company's intelligent integrated construction machine fleet. The equipment integrates more than ten core technologies such as RTK high-precision satellite positioning, automatic control, and 3D model solving, realizing the automatic control of the posture and position of the bulldozer and grader blades, reducing the professional skill requirements of the operator while meeting the standardized operation requirements. The roller uses intelligent path planning and automatic obstacle avoidance and other functions to accurately control the compaction overlap width, realize the quality control of the entire compaction process, and solve the problems of leakage, underpressure, and overpressure without human intervention.

Compared with traditional machinery, such intelligent integrated construction machinery groups have realized the automation, intelligence and standardization of the construction process. "The coordination of machinery groups can smoothly connect the processes, avoiding idleness and waiting. Moreover, the construction is not controlled by day and night, which can improve the construction efficiency by more than 50% and greatly shorten the construction period." The above-mentioned relevant person in charge introduced that the roadbed of airport and high-speed rail projects has strict requirements on construction accuracy, and the company's intelligent integrated construction machinery groups have more advantages.

"In addition to Yaoqiang International Airport, our equipment is also used in the construction of the Tianjin-Weihe High-speed Railway Project and the Wei-Su High-speed Railway Project, achieving one-time horizontal and vertical breaking. The compaction compliance rate has increased to more than 98%, and the construction efficiency has increased by more than 30%. At the same time, the input of surveyors and auxiliary workers has been greatly reduced." The relevant person in charge said that the intelligent integrated construction fleet has lowered the threshold for drivers and is also very friendly to novice drivers. "In the past, bulldozers and other projects with high precision requirements generally required experienced drivers. Now our intelligent integrated construction fleet can also be driven by drivers who have just entered the industry, and the cost of hiring drivers can be reduced by 30%." The person in charge introduced that the company's intelligent construction solutions and equipment have many subdivided products according to construction needs, and can also enable personnel to operate through remote controls, making it more convenient to view the working environment.
Smart helmets and welding chips make construction safer
Behind the intelligent construction that empowers engineering construction is the transformation and upgrading of the construction industry towards industrialization, digitalization and greening. "We have introduced the smart safety helmets that were previously used in the emergency field to assist in inspections into the construction scene. At the same time, we have also developed welding chips for hot work." On the 24th, Shandong Wanqun Information Technology Co., Ltd. received a visit from the Zibo Construction Engineering Quality Safety and Equipment Management Association. One of the company's flagship products, the smart safety helmet, was placed on the table in the conference room.
"We are a well-known private enterprise in smart construction sites and smart safety construction." The relevant person in charge of the company said that the company actively explored the market outside the province. Starting from February 14 this year, it received orders from other provinces, and the workers were busy assembling equipment. The company's equipment has also been sold abroad, following Chinese construction companies out of the country.
Towards smart construction
This year, smart construction application scenarios will be fully covered in 16 cities
Last year, the Shandong Provincial Department of Housing and Urban-Rural Development issued the "Implementation Plan for Vigorously Promoting Intelligent Construction in Shandong Province and Promoting the Industrialization, Digitalization and Greening Transformation and Upgrading of the Construction Industry", which proposed that by the end of 2025, Shandong will cultivate more than 30 backbone enterprises of intelligent construction, and the application scenarios of intelligent construction will be fully covered in 16 cities. By the end of 2030, more than 80 backbone enterprises of intelligent construction will be cultivated, and more than 700 pilot enterprises and projects of intelligent construction will be built in total, and the proportion of appropriate technologies in large and medium-sized construction projects will reach 70%.
The construction of key projects has provided application scenarios for the development of intelligent construction in Shandong. Intelligent construction technology and products are becoming a new driving force for promoting scientific design, safe construction, quality improvement and efficiency improvement of key projects. In recent years, Shandong has selected four provincial-level intelligent construction pilot cities, namely Zibo, Jining, Rizhao and Dezhou, and formed a "1+4" pilot pattern with the national pilot city of Qingdao. It adheres to the working idea of stimulating new quality productivity of the industry with digital intelligent construction, and comprehensively improves the level of intelligent construction of construction projects in Shandong Province. At the same time, the province is striving to build 100 pilot enterprises and 102 pilot projects.
