Introduction
Interpretation of the Technical Standard for Foundation Treatment of Petrochemical Equipment Hoisting
1. Background and Significance of Standard Formulation
To ensure the safety and economy of hoisting operations of large petrochemical equipment, this standard was formulated under the guidance of the Ministry of Housing and Urban-Rural Development and combined with years of practical experience. It aims to unify the technical requirements for foundation treatment and improve project quality and construction efficiency.
2. Comparative analysis of standard frameworks
| Standard dimensions | General principles | Terms and symbols | Basic provisions |
|---|---|---|---|
| Core content | Clarifies the purpose and scope of foundation treatment for hoisting | Defines key terms and symbol systems | Specifies basic requirements and technical indicators for foundation treatment |
| Scope of application | Applicable to the hoisting of large petrochemical equipment | General terms and symbol systems | Technical details of various foundation treatment methods |
| Innovation points | Proposed a variety of composite foundation treatment solutions | Detailed the protection measures for hidden facilities | Introduced a monitoring and acceptance standard system |
3. Implementation suggestions and precautions
Actual application case analysis
Case background:A large-scale storage tank hoisting project in a petrochemical plant has complex geological conditions and a collapsible loess layer.
Solution:The rigid pile composite foundation method combined with the replacement method is adopted, with a pile spacing of 5 times the pile diameter, a replacement depth of 2.0 meters for the soft soil layer, and a monitoring system is set up to track the foundation stability in real time.
Implementation effect:The foundation bearing capacity is successfully improved to the design requirements, the construction period is shortened by 15%, and the cost is reduced by 10%.
