Backfill construction method for abutment back of flow-state solidified soil bridge and culvert
The invention discloses a flow-state solidified soil bridge and culvert abutment back backfilling construction method, which comprises the following steps of: arranging templates on two sides of a backfilling area formed by a bridge and culvert abutment back and a road foundation, arranging a plastic film or geotechnical cloth on a working surface to be backfilled along the templates, and then pouring flow-state solidified soil in a layered manner, and finally, a plastic film or geotechnical cloth is folded in half to cover the upper surface of the flow-state solidified soil, the formwork is removed for maintenance, the flow-state solidified soil is applied to bridge and culvert abutment back backfilling construction, dead-corner-free backfilling can be conducted in a narrow space by means of the characteristic that a flow-state solidified soil solidified body is good in self-supporting performance, and the construction efficiency is improved. The self-hardening property of the flow-state solidified soil is good, so that the solidified body does not extrude and push the abutment back of the bridge and the culvert, the stress condition of the bridge and the culvert is good, and the problem that the settlement amount is too large after a traditional material is backfilled is effectively solved.
本发明公开了一种流态固化土桥涵台背回填施工方法，在通过桥涵台背与道路基础组成的回填区域两侧设置模板，并在待回填作业面沿模板设置塑料薄膜或土工布，随后将流态固化土进行分层浇筑，并最后将塑料薄膜或土工布对折覆盖流态固化土上表面，撤下模板进行保养，通过将流态固化土应用于桥涵台背回填施工中，利用流态固化土固结体自立性较好的特性，狭小空间也能无死角回填，流态固化土自硬性好使得固结体对桥涵台背无挤压推移，桥涵受力条件较好，并且有效解决了传统材料进行回填后沉降量过大的问题。
