| 摘 要： | 后张法预应力灌浆充实孔道的作用是保护预应力钢筋及提高整体结构的承载力。因材料、施工原因及灌浆材料泌水蒸发后,而在浆体凝固时产生一些孔隙[1]。因此减少这些孔隙是预应力灌浆的关键。本文探讨了通过对灌浆工艺关键点的控制,防止孔隙产生,保证灌浆的密实度。

| Abstract: | That the post-tensioning method prestressing force pours liquid mortar enriching the duct effect is to protect the prestressing force reinforced bar and improves the entirety structure's to bear the weight of a force.Mi Shui evaporates the queen because of material,the cause being under construction and injection material,produce but a few small openings during the period of the thick fluid body solidifies.Cutting down these small openings therefore is prestressing force injection key.The main body of a book has been discussed by controlling to injection handicraft strategic point,closely knit degree preventing a small opening from coming into being,swear to form a vesicle. |
