Rapid impact compactor treatment foundation backfilling

In the video, two rapid impact compactors are dealing with foundation backfilling.

The working pressure of hc04 and HC08 is 16MPa, and the working flow is ~110l/min, which can be adapted to 7-13t excavator or 1-2T loader; Hc12 and hc16 rapid impact compactors have a working pressure of 16MPa and a working flow of ~130l/min. They are used with 18-30t excavators or 3-4t loaders; Hc20 working pressure 16MPa, working flow ~130l/min, suitable for 25-36t excavator or 4-5t loader; Hc36/hc42 also has a working pressure of 16MPa and a working flow of ~160l/min. It is driven by a 30-40t excavator or a 5-6t loader; Hc60 working pressure 21MPa, working flow ~350l/min, with 36-49t excavator or loader above 8t; The working pressure of hc84 rapid impact compactor is 21MPa, and the working flow is ~350l/min, which is suitable for 40-60t excavator or loader above 12t; Hc150 has a working pressure of 32Mpa and a working flow of ~600l/min, which is suitable for excavators with a capacity of more than 70t or excavators with a capacity of more than 49T. 

HC series rapid impact compactor can be matched with excavators or loaders of various brands on the market. The installation is very simple and the operation is convenient. After purchase, the after-sales staff will also come to the door for installation and commissioning, so there is no need to consider how to install it.

The effective compaction depth of HC series high-speed hydraulic compactor can reach 10m at most and 0.4m at least. In the subgrade filling construction, hc36 rapid impact compactor is mostly used, and hc42 is also used in a small part. HC series rapid impact compactor has 3 tamping gears, which is suitable for PLC Remote Control of tamping intensity and frequency. 

After the test, after the bridge back transition area with 96% compactness is reinforced with 3-block and 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 mostly about 100mm, the settlement in the repeated rolling part of the heavy-duty earth truck is 20~60mm, and after the normal layered filling of the high fill subgrade, the reinforcement settlement is 120~180mm every 2m. The old subgrade of the widened road is excavated and reinforced after rolling, with an average settlement of 200~250mm, You can choose a suitable high-speed hydraulic compactor according to the above test data.
