Prestressed concrete pipe pile logistics management service specifications
2Expert Interpretation
This article deeply interprets the WB/T 1117-2021 Prestressed Concrete Pipe Logistics Service Specification, covering the technical requirements for the entire process of loading, warehousing and transportation, including equipment selection, safe operation guidelines and 6 key service quality indicators, providing a standardized implementation reference for construction logistics companies.
Analysis of the core content of the standard
| Key links | Core requirements | Technical indicators |
|---|---|---|
| Loading operation | Two-point/four-point lifting specifications | Lifting rope angle ≥45° |
| Road transportation | Layered loading and fixing | Wind speed ≤13.8m/s |
| Warehouse management | Stacking layer control | Outer diameter 500-600mm≤9 layers |
Key points of technical implementation
Lifting case: Pipe piles with a length of less than 15m should be lifted at two points using special hooks, with the lifting point located 0.21L from the end (L is the length of the pipe pile).
Transportation specifications: When transporting with a semi-trailer, anti-slip pads must be installed between each layer of pipe piles, and the spacing between bolting points should not exceed 3m.
Analysis of Standard Evolution
Compared with previous practices, this standard clarifies for the first time:
- Special processing requirements for spliced piles
- Specifications for the construction of information-based traceability systems
- Complaint handling mechanism based on GB/T 19012
Service quality evaluation system
| Indicator | Calculation formula | Industry benchmark value |
|---|---|---|
| Order on-time completion rate | (Number of orders completed on time/Total number of orders)×100% | ≥95% |
| Cargo damage rate | (Loss quantity/Total amount payable)×100% | ≤0.3% |
