Reabutment back backfilling structure using novel backfilling material and construction method of abutment back backfilling structure
The invention provides an abutment back backfilling structure using a novel backfilling material and a construction method thereof.The abutment back backfilling structure using the novel backfilling material comprises a bridge abutment, the backfilling material arranged in an abutment back area and a broken stone hardcore, a drainage pipe is arranged in the broken stone hardcore, and the specific construction method comprises the following steps that surveying and lofting are conducted; filling soil close to the bridge abutment is excavated away through an excavator till an abutment back base is excavated, the side, away from the bridge abutment, of the filling soil is trimmed into a step shape, and an embankment step is formed; foundation pit treatment is conducted, specifically, a base and four walls are compacted and leveled, and then a broken stone hardcore is laid on the base; material backfilling is conducted, specifically, a layered pouring mode is adopted for liquid soil backfilling, and a liquid soil structure needs to be formed through a launder during pouring; and maintaining the surface to keep the surface wet. According to the structural design of the novel backfill material, the novel backfill material is adopted as the backfill material, and according to a layered and sectioned pouring mode, the good effects that rolling is not needed, operation is easy, the construction period is effectively shortened, and differential settlement is eliminated are achieved.
本发明提出一种使用新型回填材料的台背回填结构及其构造方法，新型回填材料台背回填构造包括桥台、设置在台背区域内的回填材料以及碎石垫层，所述碎石垫层内设有排水管，具体构造方法包括以下内容：测量放样；采用挖掘机将紧邻桥台的填土挖除，直至挖到台背基底，远离桥台一侧修整为台阶状，形成路堤台阶；基坑处理：将基底和四壁压实整平，然后在基底铺设碎石垫层；材料回填：液态土回填采用分层浇筑的方式，浇筑时需采用流槽形成液态土结构；表面进行养护，保持其表面湿润。本发明的新型回填材料的构造设计，采用新型回填材料作为回填材料，按照分层、分区段的浇筑方式，从而实现无需碾压、操作简单、有效缩短工期、消除差异沉降等良好效果。
