As shown in the figure above, a high-speed hydraulic rammer installed on a loader or excavator is used to reinforce or tamp small areas, new and old subgrade joints, and road filling and excavation joints, with high efficiency and good results.
When the back of the bridge and culvert abutment is reinforced or tamped, the first gear 15-20 hammer or second gear 10-15 hammer shall be used to tamp the center of the hammer 80cm away from the structure.
There are various methods.
The one-time backfilling depth is large, and the construction efficiency is greatly improved.
The high-speed hydraulic rammer is used to hit the tamping plate with cushion and static pressure on the ground.
Therefore, SD high-speed hydraulic compactor effectively reduces the post construction settlement value of the subgrade and improves the service life of the highway subgrade.
Single wheel roller, impact compactor, dynamic compactor, etc.
It is not easy to form surface hardening in the foundation treatment.
Today, we will talk about hydraulic compactor.
have different effects.
In short, the road construction backfilling is to tamp the subgrade.
At the same time, the compactness after tamping with high-speed hydraulic rammer can fully meet the quality requirements of abutment backfilling.
The high-speed hydraulic rammer can obtain more uniform compactness within a larger depth range.
Compared with the traditional construction method, the tamping machine is flexible and convenient, and the corners of the road can also be impacted and tamped.
After later construction, the natural settlement rate will be reduced, and the compactness will be higher and the subgrade will be more stable.
I hope it is helpful to you..
According to the investigation of the hydraulic tamping effect diagram, the highway constructed by high-speed hydraulic tamping machine has successfully solved the problem that large compacting machinery cannot tamp and small compacting machinery has low tamping efficiency.
The high-speed hydraulic ram has three gears: first gear 0.6m, second gear 0.9m and third gear 1.2m, which correspond to different heights of the weight hammer.
Large area construction effect picture: To sum up, do you know anything about high-speed hydraulic rammer.
When Xiaobian or Xiaobai heard the name, he thought it was a network red hydraulic compressor.
The working principle of hydraulic ram and hydraulic press is basically the same, which can be said to be close relatives.
The tamping construction of the tamping machine saves the compaction machinery and small road rollers in coordination with the repeated layered backfilling construction.
Impact rammer High speed hydraulic tamping Construction Backfill technology Great change High speed hydraulic tamping machine What is a high-speed hydraulic tamping machine? It is called a hydraulic tamping machine in the industry.
After using high-speed hydraulic compactor to work on the subgrade, the subgrade can be more dense, even and consolidated.
Through the tamping plate, the ground is tamped with strong and uniform penetration capacity.
The tamping of backfill materials saves 3-5 yuan per cubic meter, saving energy and consumption.
