energy impact compaction can be used with loaders or excavators, and rely on the hydraulic power of excavators or loaders to quickly tamp the subgrade and foundation. energy impact compaction is a new type of road foundation compaction equipment, which has the advantages of loader and compactor with convenient transfer and high construction efficiency. It is especially suitable for mountain roads and narrow construction sites. It is more conducive to the weak rolling area of energy impact compaction, and further fills the loopholes of traditional road compaction and traditional dynamic compaction technology.
Compared with traditional compaction equipment, energy impact compaction has high compaction energy, large impact depth, flexibility and multi-purpose. In order to meet the compaction needs of different foundations, the compaction energy can be adjusted. In addition to the same model classification rules, energy impact compaction and impact roller also have the characteristics of "compaction" and "rolling". The main feature of impact rolling is that the impact rolling "rolling" has a large drop due to its polygonal and non-circular characteristics, and has "compaction" in the construction process. Therefore, the impact strength is large, and the impact depth is also large.
As a working device, the hydraulic compactor is usually installed on the wheel loader or hydraulic excavator. Its hydraulic and circuit power supply comes from the loader or excavator, and its support. It includes a box, hammer, hydraulic system, electrical control system, etc. The hydraulic system of energy impact compaction mainly includes hydraulic cylinder, battery, electromagnetic reversing valve, etc. It is provided by loader or excavator, so its hydraulic system and loader or excavator are set as a complete hydraulic system.
The effective compaction depth of HC series energy impact compaction can reach 10m, with a minimum of 0.4m. It is widely used in subgrade filling construction. Hc36 energy impact compaction also uses hc42 in a small part. HC series loader hydraulic tamping machine has three tamping gears, which is suitable for PLC Remote Control of tamping intensity and frequency. After the test, the transition area of the bridge back with 96% compactness is reinforced with a 3-level 9-hammer. The settlement near the abutment is more than 100mm, mostly 150~250mm, some about 300mm, the settlement in the normal rolling area is 100mm, the settlement in the heavy-duty earth moving vehicle is repeatedly rolled and the settlement is 20~60mm. After the high fill subgrade is normally filled in layers, it is filled once every 2 layers, and the settlement is 120~180mm. After the excavation and rolling of the old subgrade of the widened road, it is strengthened, with an average settlement of 200~250mm, A suitable high-speed hydraulic compactor can be selected according to the above test data. HC energy impact compaction is equipped with a standard grounding circle with a diameter of 1m. The width of upper steps excavated everywhere is mostly 1.2~1.5m. After the steps are compacted in a single row or double rows, continue to tamp the joint between the steps and the new subgrade. When the new ordinary subgrade is weak, at least the lower steps should be covered. The reinforcement effect is the best when the top of the step is not filled or the filling is not more than 500mm.
There is no drive system inside the energy impact compaction, so it needs to be equipped with excavator or loader to realize transfer, compaction and other operations. During installation, the bucket needs to be removed, and then the after-sales engineer of the manufacturer installs and links the energy impact compaction to the loader according to the requirements. After installation, commissioning is carried out to ensure that the equipment can maintain a good state, further improve work efficiency, and save construction time and cost.
