Bridge abutment backfilling method and backfilling structure of urban bridge
The invention relates to the technical field of urban bridge construction, in particular to an abutment backfilling method and a backfilling structure of an urban bridge, which comprise the following steps of: cleaning a foundation pit in a to-be-backfilled area enclosed by an abutment, two retaining walls and a bridge approach before backfilling the foundation pit; the base is kept dry and free of sewage, garbage and other sundries; measuring and setting out are conducted, according to the backfill range of the backfill soil and the light foam concrete, the backfill area of the backfill soil and the light foam concrete is measured and released through a total station, the backfill height is measured and released through a level gauge, and the retaining wall and the abutment back are marked; the abutment back and the retaining wall back are backfilled with the light foam concrete and are transited to the outer side layer by layer, and the cross beams, the butt strap and the plain concrete transition area are arranged on the top face of the foam concrete, so that differential settlement of abutment back backfilling is eliminated.
本发明一种城市桥梁的桥台回填方法及回填结构涉及城市桥梁施工技术领域，具体涉及一种城市桥梁的桥台回填方法及回填结构，包括以下步骤：将桥台、两个挡土墙及桥引道围成的待回填区内的基坑在回填前将基坑清理干净，保持基地干燥、无污水、无垃圾等杂物；测量放线，根据回填土和轻质泡沫混凝土的回填范围用全站仪测放出回填土和轻质泡沫混凝土的回填区域,并用水准仪测放出回填高度,在挡土墙和台背处做出标记；本发明通过在台背及挡土墙后背采用轻质泡沫混凝土回填并逐层向外侧过渡，并在泡沫混凝土顶面设置横梁、搭板和素混凝土过渡区的形式消除台背回填的不均匀沉降。
