Application fields of rapid impact compactors, processing effects of rapid impact compaction of loaders in various fields

We all know that rapid impact compaction are used to deal with road subgrades and foundations, so some friends do not know where they can be used on highways. The following is a brief introduction to the application fields of rapid impact compactors. The rapid impact compaction machine installed on the loader The construction effect of rapid impact compaction in various fields.

The construction field of rapid impact compactor is very extensive. High-speed hydraulic compactor can be seen on roads, railways, and even airports and ports. Sometimes it is installed on loaders and excavators. , Most of them are rapid impact compactors used for loaders, and the models are mostly Taian Hengda HC36 and HC42.

Reinforcement of V-shaped ditch with filling length less than 20 m

1) The original road surface shall be leveled after clearing the surface, rolled before filling, and the original road surface shall be fully rammed with the third gear (up to high power) of a rapid impact compaction machine, and each tamping point shall be rammed 12 times.

2) Every time the backfill soil is raised by 2m, the rapid impact compactor will ram the compacted roadbed and add ribs. The scope of reinforcement is the full width of the roadbed. The points are distributed in a triangle with a distance of 1.5m between the hammer centers of the rapid impact compaction equipment. Ramming 12 times. The rapid impact compactor has three gears. When the subgrade is backfilled to a sufficient length, the use of basic rolling equipment can ensure the actual effect of compaction, and no further ribbing will be carried out.

Reinforcing the "three backs" backfill

The rapid impact compaction machine is ribbed, which can reasonably be manipulated to move down after work, and enhance the work efficiency.

The points can be arranged more than 30cm away from the back of the bridge and culvert. The points are distributed in a triangle with a distance of 1.5m along the center of the rapid impact compactor. The range of ramming is to widen the back of the platform to 2m of the subgrade. Tamper point rammer 9 times. When the first hammer is close to the building wall, the second gear of the rapid impact compaction equipment can be used to carry out tamping. The impact energy can reach the maximum power, and the actual effect of engineering construction is remarkable.

Retaining Wall Back Control Points

The points are arranged more than 50cm away from the back of the mortar retaining wall, and the points are distributed in a triangle with a distance of 1.5m along the center of the rapid impact compactor. times, each ramming point ramming hits 9 times. The ramming point of the rapid impact compaction machine close to the wall can adjust the ramming energy to 50% to reduce the damage to the retaining wall structure. The second row can be constructed according to the rated ramming energy.

Reinforcing the junction of the new and old roadbeds

The rapid impact compaction machine is distributed within the range of 4m at the junction of the old and new subgrades. The points are distributed in a triangle with a distance of 1.5m along the center of the hammer. Each time the backfill is lifted 2m, the ramming is performed once, and each ramming point is rammed 12 times.

The above content is to deal with various problems of rapid impact compactor in highway construction, and to show the basic construction data, then why should the roadbed of the highway be compacted? What is the role of subgrade compaction? Let's expand our knowledge and briefly introduce the role of subgrade compaction.
