Abstract

The invention relates to the technical field of building construction, and discloses a roadbed filling construction method. The method comprises the following steps: step 1, roadbed lofting; step 2, site cleaning; step 3, compacting before filling; step 4, elevation measuring: measuring, detecting, recording and calculating the filling elevation of each layer of a compacted roadbed; step 5, fillerselecting: selecting and determining a roadbed filler; step 6, embankment feeding: carrying out layered filling treatment and paving leveling treatment on the roadbed to be fed, and carrying out filler water content detection on the roadbed subjected to watering and airing; step 7, leveling and compacting: performing layered static pressing and layered vibration pressing on the to-be-compacted roadbed according to designed filler compaction conditions to obtain a compacted roadbed; and step 8, finishing and maintaining: finishing and reinforcing a slope, a width, a height and flatness of an embankment slope and the roadbed of the compacted roadbed. Problems that an existing roadbed filling construction method is low in construction efficiency and high in construction cost are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a roadbed filling construction method. Background technique [0002] The subgrade is the foundation of the track or road surface. Its main function is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or trains, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic load. [0003] For the filling of subgrades, the construction method of filling subgrades with ordinary subgrade fillers is often used. However, this construction method has problems such as complex construction procedures, unsafe and reliable construction, easy slurrying of subgrade fillers, and difficulty in controlling the quality of on-site construction. However, it is impossible to quickly, safely and effectively fill the roadbed, which leads to the problems of low construction efficiency and h...
