空心板梁桥大中修顶板原始质量控制的施工技术

Construction technology about the original quality control of roof applied in large and medium repair of hollow slab bridge

上世纪80、90年代修建的桥梁桥面出现坑槽、露筋等不同程度的损坏,运营状况已经满足不了现有运输工具的需要,翻修工程越来越多,拆除空心板板梁桥面水泥混凝土铺装层时,降低对桥体冲击荷载成为一个重要课题。空心板梁桥桥面铺装大中修工程确保空心板顶板原始质量的施工技术,不仅具有现实意义,对今后各类保养大修工程施工也具有指导借鉴。

Bridges are built in the 80 and 90＇s of last century,whose decks appear pits,exposed tendons in different degrees of damage,and operation condition of these bridges can not meet the requirements of existing transportation tools.With more and more renovation,it becomes an important subject that the impact load on bridge is reduced when removing the cement concrete pavement layer of hollow plate girder bridge pavement. Construction technology,which can control the original quality of roof applied in large and medium repair of hollow slab bridge,not only has practical significance,but also can offer references for all kinds of maintenance overhaul engineering construction in future.
