The parameters of HC rapid impact compactor mainly include impact energy, effective depth, hammer weight, etc., of which 36KJ represents the impact energy. The HC36 rapid impact compactor is generally used in highway construction, which can effectively deal with the side of abutments and culverts, combining old and new roads. Department, etc.

1. Parameters of HC rapid impact compactor

They can be adapted to 7-13t excavators or 1-2t loader; HC12 and HC16 high-speed hydraulic compactor working pressure 16Mpa, working flow ~130L/min, with 18-30t excavator or 3-4t loader; HC20 working pressure 16Mpa, working flow ~130L/min, Suitable for 25-36t excavator or 4-5t loader; HC36/HC working pressure is also 162Mpa, working flow ~160L/min, use 30-40t excavator or 5-6t loader to carry and drive; HC60 working pressure 21Mpa, working Flow rate ~350L/min, with 36-49t excavator or 8t above loader; HC84 high-speed hydraulic compactor working pressure 21Mpa, working flow ~350L/min, suitable for 40-60t excavator or 12t above loader; HC150 working pressure 32Mpa, working flow ~600L/min, suitable for excavators above 70t or excavators above 49t to boom. HC series rapid impact compactors can be matched with various brands of excavators or loaders on the market. Installation is very simple and easy to operate. After the purchase, the after-sales personnel will also come to the door to install and debug, no need to consider how to install.

2. Construction principle of 36KJ rapid impact compactor

In the process of highway subgrade construction in my country, in the backfilling work of bridge and culvert platform, the filling work is usually carried out after the structural construction is completed. Therefore, it is necessary to pay attention not to damage the structure during the construction process, and it is also necessary to apply sufficient compaction to the subgrade construction. However, due to the narrow construction scope on the back of the bridge and culvert, the use of large compactors will easily affect the nearby subgrade structures. If small compaction equipment is used for construction, the compaction degree of the roadbed is difficult to meet the standard, and the overall construction is very difficult. Rapid impact compaction can solve this problem well. The rapid impact compaction raises the rammer to a certain height through the hydraulic cylinder, and then releases it quickly to accelerate the fall under the combined action of gravity and hydraulic accumulator. When the rammer falls behind, it hits the static pressure tamping plate with a buffer pad on the ground, and the vertical impact force is transmitted to the ramming plate, and the ground is vigorously tamped by the ramming plate. The rapid impact compactor is mounted on the boom of a common loader. Using the movement of the loader and the flexibility of the boom, different working positions can be compacted, and the construction ground can be compacted in a single point or continuously. It is suitable for projects with narrow construction surfaces such as the back of highway bridges and culverts. Using rapid impact compaction can effectively strengthen the compaction of the bridge subgrade, avoid the impact of the excessive impact force of the rammer on the surrounding subgrade, and effectively deal with the safety problem of bridge jumping.

3. Construction specifications for 36KJ rapid impact compactor

The HC36 rapid impact compactor has a total of 3 gears. In order to study the harm of different gears to the actual effect of rib compaction, the qualified foundation surface was rolled at the junction of the old and new foundations, and the red plum blossoms were used to arrange the tamping points. Select different points I, II and III to add ribs 18 times, each tamping 3 times, observe the downward movement with a spirit level, and take 3 points for each vehicle gear standard to observe the downward movement. It can be seen from the observation results that the best practical effect of III is that of grade II, the actual effect of I is the worst. According to the evaluation data, the actual effect of the three ramming strikes of III exceeds or is close to the actual effect of the first and second grades of ramming. Hence the application. When the HC42 rapid impact compactor is ribbed to compact the loess layer foundation, the Ⅲ rib should be selected for the highest efficiency.

HC rapid impact compactor is very effective in foundation treatment construction, with high tamping frequency, good compaction effect, convenient transfer, safety and environmental protection. It is a good choice for basic treatment schemes such as treatment, combined treatment of old and new roads, urban transportation, and landfill.
