预应力桥梁施工中,孔道压浆质量差,导致预应力桥梁上部构造预应力过早损失,预应力筋过早锈蚀,结构开裂损坏影响结构的耐久性。通过对预应力桥梁结构纵向、横向、竖向预应力孔道压浆的各个环节进行试验,规范操作,最终取得较好效果。
預應力橋樑施工中,孔道壓漿質量差,導緻預應力橋樑上部構造預應力過早損失,預應力觔過早鏽蝕,結構開裂損壞影響結構的耐久性。通過對預應力橋樑結構縱嚮、橫嚮、豎嚮預應力孔道壓漿的各箇環節進行試驗,規範操作,最終取得較好效果。

The prestressed bridge construction, duct grouting of poor quality, leading to premature prestress prestressed bridge superstructure damage, premature corrosion of tendons, structural cracking damage, affecting the durability of the structure. Prestressed bridge structures on vertical, horizontal, vertical duct grouting of all aspects of prestressed concrete strict requirements and standards, achieve better re- sults.
