Problems solved by technology
[0008] (1) The traditional compaction devices are all carried out by direct rolling. When compacting, it is easy to have the problem of partial compaction and pores, which will affect the quality of the roadbed and affect the quality of the entire road surface. quality;
[0009] (2) At the same time, for different road surfaces, general devices cannot effectively adjust the applied pressure and cannot meet different compaction requirements;

The invention discloses a rapid compaction device based on a subgrade restricted region. The rapid compaction device comprises a working barrel and a worktable, wherein the working barrel is fixedly connected with the worktable through an assembling mechanism; a rolling mechanism is arranged in the working barrel; a plurality of branch holes are arranged in the surface of the working barrel; the branch holes are internally provided with pneumatic compaction mechanisms; the rolling mechanism comprises a vibration seat mounted in the working barrel; metal shafts are connected with two ends of the working barrel; a rotary metal barrel is connected with the outer ends of the metal shafts; a mounting frame is connected with one side of the surface of a bearing seat; a pressure-bearing seat is connected with the top end of the surface of the bearing seat; the top end of the pressure-bearing seat is connected with a pressure-bearing rod; the top ends of the pressure-bearing rod at two ends are fixedly connected through a centralizing seat; the centralizing seat is fixedly connected with a worktable through a pressure applying mechanism; a subgrade is comprehensively compacted through a combined compaction manner and the compaction efficiency is improved; in a working process, the noise pollution is small; the rapid compaction device can be used for carrying out compaction work with different requirements on different subgrades and has strong practicability.
Description
technical field [0001] The invention relates to the technical field of road construction, in particular to a rapid compaction process and device based on a roadbed restricted area. Background technique [0002] Subgrade refers to the belt-shaped structure built according to the location of the route and certain technical requirements as the foundation of the road surface. It is the foundation of railways and highways. The subgrade is a linear structure built with soil or stone. The subgrade built under good geological, hydrological and climatic conditions. In terms of materials, roadbeds can be divided into three types: soil roadbeds, stone roadbeds, and earth-rock roadbeds. [0003] The subgrade is a structure that directly supports the track formed by filling or excavation. It is also called the substructure of the line. The subgrade is connected with bridges and tunnels to form a line. The subgrade has two basic forms depending on the terrain conditions: Embankments and...
