At 10 a.m., the reporter came to the Greenland Shandong International Financial Center which is under construction. The project builders of the Second Company of China Construction Eighth Engineering Bureau are working intensively to present a super high-rise boutique landmark building to the spring city of Jinan, once again refreshing the Qilu skyline!
Greenland Shandong International Financial Center (IFC) is located at the intersection of the high-density comprehensive urban functional area and the landmark Central Park in Jinan's central business district. It includes a main tower, a 100-meter tower, a podium and an underground garage, with a construction area of 409,000 square meters, of which the main tower is 428 meters tall, with 88 floors above ground and 4 floors underground. It is expected to be completed and put into use in 2021. After completion, it will become the tallest building in Shandong.
A number of "black technologies" were used for the first time in the province to help "jump up"
According to the staff, the project used a variety of new construction technologies that were used for the first time in Shandong Province during the construction process, helping "Shandong's No. 1 Highest" to continue to be "highest" Jump up."
"dragon absorbs water" - large volume concrete rapid pouring technology. In order to complete the concrete pouring of the foundation floor with a maximum thickness of 12.1m quickly and with high quality, the project department used five concrete mixing stations and deployed 110 concrete mixer trucks to deliver materials together. The "chute + concrete conveyor + truck pump" pouring method was adopted. The on-site layout Four large chutes were built, like four giant dragons hovering over the construction site, with an average speed of 370m³ and a maximum speed of 670m³. In the end, it only took 56 hours to complete the 4,100-square-meter tower foundation floor and 21,000 cubic meters of concrete pouring, refreshing It has set a number of indicators for large-volume concrete pouring, breaking and surpassing the historical record of single pouring in Jinan City, and opening a new chapter in large-volume concrete pouring.
"Tongtian Lux" - attached self-climbing luffing jib tower crane external construction technology. This is a new technology independently developed and applied by the project department for the first time, taking into account many factors such as lifting weight, lifting times, and distribution characteristics of the steel structure. Its maximum working range is 55 meters and its maximum lifting capacity is 80 tons. It can meet the lifting tasks safely and efficiently, providing guarantee for the rapid and high-quality construction of the project's civil engineering and steel structures.
"Tower Building Artifact" - low-position, few-fulcrum intelligent hydraulic jacking platform technology, also known as "intelligent building machine". This is also the first time this technology has been used in Shandong Province, solving the technical problems in the construction of the vertical structure of the tower core tube in one fell swoop , quality, safety, fire protection, environmental protection, energy saving and other problems. The project department also improved and optimized the installation process, and innovatively applied modular overall installation technology. The truss module was assembled and welded on the ground at one time. With the help of a luffing tower crane, the modules were lifted in the air and connected in the air. Taking full advantage of the advantages of safe and stable ground operations, fast operation speed, and high installation accuracy, it not only shortened the installation period of the entire truss by nearly 30%, but also reduced the risks of high-altitude operations, taking into account quality, safety, and green construction. and other various needs.
In addition, the use of HBT90-CH ultra-high-pressure concrete delivery pump ensures synchronous climbing between the construction elevator and the top formwork system, providing vertical transportation for construction workers. Its maximum conveying height can reach 580 meters. The core tube is equipped with two HGY21 placing machines fixed on the top form truss and lifted together with the steel platform. It can rotate 360 degrees. The discharge port is connected to the string barrel for concrete pouring. There are 7 medium-high-speed variable frequency construction elevators inside and outside the core tube, equipped with 13 ladder cages, which are divided into high and low zones. The elevator operates through a specially designed attachment system, which uses a rolling attachment wall to connect to the jacking platform, allowing direct access to the top mold working platform.
"The highest in Shandong" is also the "first in intelligence"
Zhu Zicong said that the Second Company of China Construction Eighth Engineering Group Co., Ltd. strives to promote the modernization of smart construction and has turned "the highest in Shandong" into the "first in intelligence".
In terms of project design and management, the project department takes the BIM information model as the core. The deepening and optimized design of each major are all based on the BIM model, making the general contractor the real core of design management.This not only significantly reduces project risks and reduces unknowns during project implementation, but also makes management more technological and refined, greatly improving construction efficiency. At this stage, the
project has adopted technologies such as the Internet + quality management system and drone aerial photography. All the CAD construction electronic drawings, construction plans, operating procedures and manufacturer information of each component are entered into the QR code. All employees can scan the code to understand and learn the corresponding specific specifications and operating procedures for the construction process; use drone aerial photography Technology, analyze the on-site topography, assist site planning, generate 720 panoramic views and construction progress charts, facilitate managers to understand the on-site image progress and safe and civilized construction conditions in a timely manner, and provide reference for safety, quality, and plan management.
It is understood that a full set of dust prevention and control equipment was introduced and installed during the construction. This equipment includes an air quality monitoring device and an automatic spray device, which enables 24-hour full-time monitoring. Once dust pollution exceeds the standard, it will automatically link the spray facilities installed in tower cranes, enclosures and other areas to spray water mist to reduce dust and ensure air quality. Excellent, practice green construction and production methods to help Quancheng Jinan win the "Blue Sky Defense War".
pierced the blue sky and entered the clouds, refreshing the Qilu skyline. Greenland Shandong International Financial Center (IFC), as a new landmark in Qilu, not only sets a new height for Shandong architecture, but also serves as a new window for Shandong to connect with the world, a new image for Shandong as an economically and culturally powerful province, and a new business card for Jinan to communicate with the world. The project construction personnel of China Construction Eighth Engineering Bureau No. 2 Company will strive to do every job to the extreme, continue to build a "first-class quality" architectural masterpiece with "first-class efficiency", and contribute "to the construction of a "big, strong, beautiful and prosperous" modern spring city" China Construction Wisdom” and “China Construction Strength”.
