公路桥锚碇斜向预应力孔道灌浆试验研究

Test and Study of Oblique Prestressed Drill-way Grouting Technology of Anchor Block of Road Bridge

润扬长江大桥南北锚碇锚固体系采用预应力技术,为保证斜向预应力孔道的灌浆质量及预应力结构的耐久性,施工前进行了科学的灌浆配合比试验及孔道仿真模拟试验。

Engineers adopted the prestress technology in construction of the anchor system of north anchor blocks and south anchor blocks of Runyang Changjiang River Bridge. To ensure the quality of oblique prestressed drillway grouting and durability of prestressed structures, engineers made a scientific grouting match ratio test and a drillway simulation test before construction.
