Qingdao Zhongrui Logistics Workshop Project

The Qingdao Zhongrui Logistics Workshop Project is located in the core logistics industrial park of Qingdao. It is a key project invested and constructed by Zhongrui Logistics Enterprise to improve logistics operation efficiency and expand business scale. The main construction content includes a modern large-scale logistics workshop and supporting facilities for warehousing, sorting, and transportation scheduling.

Project Challenges and Solutions

Foundation Construction Difficulties Caused by Complex Geological Conditions

Challenge: Some areas in Qingdao have complex geological conditions. The project construction site has problems such as uneven soil layers and high groundwater levels, which bring great challenges to foundation construction. Improper foundation treatment may easily lead to uneven settlement of the building, affecting structural stability.
Solution: Based on the survey results, the design team adopted a pile foundation scheme, using high-strength prestressed concrete pipe piles that penetrate into stable soil layers to effectively disperse the load of the upper structure. During construction, the verticality and penetration depth of the piles were strictly controlled, and professional equipment was used for pile foundation testing to ensure that each pile meets the bearing capacity requirements, fundamentally ensuring the stability of the foundation.

Precision Control in Long-Span Steel Structure Installation

Challenge: To meet the needs of large freight vehicles entering and exiting and large shelves placement, the logistics workshop adopts a long-span steel structure design with a maximum span of [X] meters. During the installation of long-span steel structures, deformation is likely to occur due to factors such as self-weight and welding stress, affecting installation accuracy and structural safety.
Solution: The construction team formulated a scientific installation plan, adopting the method of "segmental hoisting and overall correction". First, steel structure components were prefabricated in the factory to strictly control the dimensional accuracy of the components; during on-site hoisting, high-precision total stations were used for real-time monitoring, and the position and verticality were adjusted in a timely manner after each segment was hoisted. At the same time, the welding sequence was reasonably arranged to reduce welding stress concentration, and non-destructive testing was performed on the welds after welding to ensure welding quality. Through these measures, the steel structure installation error was successfully controlled within the allowable range of specifications.

Cross-Interference Between Construction and Logistics Operations

Challenge: Since the project construction site is located near the existing operation area of Zhongrui Logistics, it is necessary to ensure the normal operation of the original logistics business during construction, which inevitably leads to cross-interference between construction and operation, such as conflicts between construction material transportation and logistics vehicle traffic, and construction noise affecting the working environment.
Solution: The project management team established an efficient coordination mechanism, divided clear construction and operation areas, and set up physical isolation facilities. Construction time and transportation routes were reasonably planned, and material transportation was carried out during non-peak logistics hours; low-noise construction equipment was selected, and the construction area was soundproofed to reduce noise pollution. In addition, special personnel were arranged for on-site coordination to promptly handle sudden cross-interference issues, ensuring that both construction and operation proceed smoothly.

Technical Highlights

Integrated Design of Intelligent Warehousing System and Building Structure: Special track bearing beams are set on the top of the workshop for installing lifting equipment of automated three-dimensional warehousing. The tracks are connected to the main steel structure through special nodes, ensuring the stability of the lifting equipment operation without affecting the overall stress of the building structure. This integrated design reduces additional support structures, saves space, improves warehousing utilization, and makes the operation of intelligent equipment more efficient and safe.
Innovative Application of Steel Structure and New Enclosure Materials: The workshop steel structure adopts high-performance Q355B low-alloy high-strength steel, which reduces self-weight while ensuring strength compared to traditional steel, reducing the foundation load. The enclosure structure uses new composite sandwich panels, which consist of two layers of color steel plates with thermal insulation materials in between, having good thermal insulation, fire resistance, and moisture resistance. This material is easy to install, greatly shortens the construction period, and has a long service life, effectively reducing later maintenance costs.
In-depth Application of BIM Technology in Full-Process Management: In the design stage, collision detection was carried out through BIM models to identify and solve conflicts between pipeline layout and structural components in advance; in the construction stage, BIM models were used for construction simulation to optimize construction procedures and resource allocation, improving construction efficiency; in the operation and maintenance stage, BIM models can be used as an important basis for equipment management and maintenance, facilitating timely mastery of the operation status of various facilities in the workshop. The application of BIM technology makes project management more refined and intelligent, effectively reducing costs and rework.
