Method for controlling abutment back backfilling construction quality
The invention discloses an abutment back backfilling construction quality control method, and belongs to the technical field of road and bridge construction. Firstly, test pieces with different pouring layers, test pieces with different stirring times, test pieces with different pouring ages, test pieces with different pouring heights, test pieces with different pouring angles, test pieces with different pouring temperatures, test pieces with different pouring humidity, test pieces with different material adding sequences, test pieces with different stirring modes and test pieces with different stirring speeds are manufactured through abutment back backfilling materials; after all the test pieces are poured and maintained, compressive strength tests are conducted on all the test pieces, and test data are recorded; and according to the measured compressive strength result, the construction process of a group of test pieces with the maximum compressive strength in the test pieces corresponding to each construction process is taken as the optimal construction process. According to the method, cast-in-place is simulated through an indoor test, the influence of each construction factor on the filler performance can be qualitatively or quantitatively analyzed, and the pavement performance of the filler can be exerted to the maximum extent by determining the strength, determining the optimal casting process and guiding the cast-in-place.
本发明公开了一种台背回填施工质量控制方法，属于路桥施工技术领域。首先采用台背回填材料分别制作出不同浇筑层数试件、不同搅拌时间试件、不同浇筑龄期试件、不同浇筑高度试件、不同浇筑角度试件、不同浇筑温度试件、不同浇筑湿度试件、不同材料添加顺序试件、不同搅拌方式试件、不同搅拌速度试件，所有试件浇筑并养护完成后对所有试件进行抗压强度试验，并记录试验数据；根据测定的抗压强度结果，每项施工工艺对应的试件中取抗压强度最大的一组试件的施工工艺为最优施工工艺。本发明通过室内试验模拟现场浇筑，可定性或定量分析出各施工因素对填料性能的影响，通过测定强度，确定最优浇筑工艺，并以此指导现场浇筑，可最大程度发挥填料路用性能。
