Post-construction abutment back backfill compaction method
The invention provides a post-construction abutment back backfilling and compacting method, and relates to the field of abutment back construction. The backfilling and compacting method for the back of the post-construction abutment comprises the following steps that firstly, a site is arranged; 2, leveling a base layer; 3, filler mixing: uniformly adopting cement soil, limestone soil, gravel and short steel fibers as fillers, carrying out centralized field mixing on the fillers by adopting plant mixing equipment or a road mixer, and carrying out sampling determination on the water content and the short steel fiber content by an inspector; step 4, paving and flattening; step 5, fully compacting; and step 6, maintaining and preserving. According to the method, the abutment back is backfilled with high-strength filler mixed with short steel fibers, the bonding force among sand particles can be effectively improved, reinforcing steel bars are additionally arranged between the filler layers, then the filler layers can be effectively prevented from deforming, the bumping phenomenon of the bridge abutment is effectively avoided, the driving comfort is improved, and the service life of the bridge abutment is prolonged. And the damage to the structure and the road surface is effectively reduced.
本发明提供一种后施工台背回填压实方法，涉及台背施工领域。该后施工台背回填压实方法，包括以下步骤：步骤一、整理现场；步骤二、整平基层；步骤三、填料拌合：填料统一采用水泥土、石灰土、砂砾以及短钢纤维，填料通过采用厂拌设备或路拌机集中场拌，由检验人员进行含水量、短钢纤维含量的取样测定；步骤四、摊铺平整；步骤五、充分压实；步骤六、养护养生。该方法采用了混合有短钢纤维的高强度填料对台背进行回填，能够有效提高砂土颗粒之间的粘结力，在填料层以及填料层之间加装有加固钢筋，进而可以有效防止填料层发生变形，有效避免了桥台发生跳车现象，提高了行车的舒适性，并且有效降低结构物与路面的损害。
