透水框架制作工艺的改进与工程经济适用性分析

Improvement of permeable framework production process and analysis of project economic adaptability

透水框架因其本身具有的消能、固滩和促淤的特点在长江中下游航道整治工程中得到了广泛应用。针对传统的杆件焊接式透水框架和改进制作工艺后的一次成型透水框架在预制所需堆场面积、模具费用和施工工艺等在工程经济方面进行比较,分析其工程经济适用性,并对其适用条件和范围提出建议。

Characterized by energy dissipation, beach solid and siltation promotion, the permeable framework has been widely used in waterway renovation project in the middle and downstream of the Yangtze River. This paper compares the traditional rod welded permeable frame and the improved permeable framework process on the requirement of yard area, tooling costs and construction technology, analyzes the engineering economic adaptability, and puts forward suggestions on the adaptable conditions and scope.
