Standardized construction method for backfilling abutment back
The invention relates to an abutment back backfilling standardized construction method, and belongs to the technical field of bridge and culvert abutment back backfilling construction. Comprising the following steps that S1, a backfill area is cleaned, specifically, the backfill area is cleaned, and it is ensured that the surface of the backfill area is flat; s2, steps are excavated in a graded mode, layered excavation is conducted on the foundation, and a step-shaped construction face is formed; s3, the grouting position is determined, and the grouting hole position is determined according to the design requirement; s4, filling is conducted, specifically, filling is conducted on the step face; s5, tiling is conducted, specifically, the whole step face is tiled through filler; s6, flattening and compacting are conducted, specifically, the filler on the step face is rolled, and grouting is conducted at the grouting position; s7, whether the step surface is qualified or not is detected, the step S3 is executed if the step surface is qualified, and the step S6 is executed if the step surface is not qualified; s8, checking and accepting; the method solves the problem that the existing bridge and culvert abutment back backfill soil settles due to various reasons to cause bump at the bridge head of the expressway.
本发明涉及台背回填标准化施工工法，属于桥涵台背回填施工技术领域。包括以下步骤：S1：清理回填区域，将回填区域进行清理并确保回填区域表面平整；S2：分级挖台阶，在地基上分层挖掘，形成台阶状的施工面；S3：确定注浆位置，根据设计要求确定注浆的孔位；S4：填料，在台阶面上进行填料；S5：平铺，将填料将整个台阶面进行平铺；S6：平整压实，将台阶面上的填料进行碾压并在注浆位置进行注浆；S7：检测是否合格，对压实的台阶面进行检测，若合格则执行步骤S3，不合格则执行步骤S6；S8：验收；本发明解决了现有的桥涵台背回填土由于各种原因发生沉降导致出现高速公路桥头跳车的问题。
