本文主要阐述单侧张拉后张法有粘结预应力梁的施工技术,通过施工技术管理,选用收缩量的水泥,降低水泥用量及水灰比,优化骨料级配,严格控制水泥用量等措施,确保高支模体系的稳定。保证整个预应力大梁的施工质量,为同类工程提供借鉴。
This paper mainly expounds the construction technology of unbonded post-tensioned bonded prestressed beams, through the management of construction technology, the selection of shrinkage of cement, reducing the amount of cement and water-cement ratio, optimizing the aggregate gradation, strictly controlling the amount of cement Measures to ensure the stability of high-mode system. Ensure the construction quality of the entire prestressed girder, provide reference for similar projects.
