Introduction
Analysis of the core content of the standard
| Technical field | Requirements of the old version | Innovations of the 2019 version |
|---|---|---|
| On-site roads | Basic traffic functions | Smart traffic management + ecological drainage system |
| Concrete production | Conventional dust removal | Fully enclosed mixing + wastewater recycling |
| Metal processing | Basic safety protection | Explosion-proof lighting + VOC recovery device |
Key Technical Requirements
1. On-site Road Management
The specification requires that the hardening rate of the main roads on the site be 100%, and that a super-high slope of 2%-4% be set on the outside of the curved section. Crash barriers must be set on high-slope sections, with a height of no less than 80cm.
2. Production Facility Standards
sand and gravel processing system must be equipped with a three-level sedimentation tank, and the sewage retention time must be no less than 2 hours. The dust emission concentration limit of the concrete mixing plant is 20mg/m³.
Suggestions for the implementation of the standard
- Establish a special fund for civilized construction (not less than 0.5% of the project cost)
- Promote the QR code equipment management system
- Carry out monthly civilized construction star rating
Technology evolution analysis
Compared with the 2008 version, the 2019 version adds 16 intelligent requirements, including:
- Online monitoring of construction dust
- Digital control of energy consumption
- Electronic fencing in dangerous areas
