摘要
在预应力混凝土轨枕生产过程中,静载抗裂性能检验作为产品出厂检验的一个重要指标,如果检验不合格,其所代表的轨枕产品将不得出厂。文章从轨枕生产过程中的原材料选用、生产工艺控制等方面进行阐述,确保轨枕出厂时预应力不受损失,静载抗裂性能检验合格,保证轨枕的使用寿命。
In the production process of prestressed concrete sleepers,the static load crack resistance test is an important index of product delivery inspection.If the test is unqualified,the sleeper products represented by it will not leave the factory.This paper expounds the selection of raw materials and production process control in the production process of sleepers,so as to ensure that the prestress of sleepers is not lost when they leave the factory,the static load crack resistance is qualified,and the service life of sleepers is guaranteed.
