The size of the HC rapid impact compactor is generally 2.45 meters to 6.3 meters high, and the dimensions of different types of rapid impact compactors are also different, such as the commonly used 36KJ rapid impact compactor. The rapid impact compaction machine is made of a tamper frame. The tamper hammer. The tamper plate. The buffer device. The weight of the hydraulic system and the electronic control system mainly comes from the tamper frame. It plays an important role and can effectively roll the filling at the junction of the old and new roadbeds. HC36 rapid impact compaction machine has the characteristics of flexible operation and wide influence, and has been successfully used in highway reconstruction and expansion projects. The application expansion of HC36 rapid impact compaction machine in engineering can also be deeply discussed in the follow-up research process.

HC series high-speed hydraulic 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.

The effective compaction depth of HC series rapid impact compactors can reach 10m, and the minimum is 0.4m. In the construction of roadbed filling, the HC36 loader hydraulic compactor is widely used, and a small part of the HC42 is also used. HC series rapid impact compactors have three compaction gears, which are suitable for PLC remote control of compaction strength and frequency. After the test, use 3 gears and 9 hammers to reinforce the bridge back transition area with a compaction degree of 96%. The settlement near the abutment is greater than 100mm, mostly 150~250mm, and some are about 300mm, and the settlement in the normal rolling area is 100mm. , the heavy earth moving vehicle repeatedly rolls and settles 20~60mm. After the high-fill roadbed is filled in layers, fill it every 2 layers to reinforce the settlement of 120~180mm, and widen the old roadbed and strengthen it after excavation and rolling. , the average settlement is 200~250mm, and the appropriate loader hydraulic compactor can be selected according to the above test data.

The standard configuration of the HC rapid impact compaction equipment is a grounding circle with a diameter of 1m, and the width of the upper steps excavated in various places is mostly 1.2~1.5m. After the steps are staggered in single or double rows, the junction between the steps and the new roadbed will continue to be compacted. When the new common subgrade is weak, at least the lower steps should be covered. The best reinforcement effect is when the top of the step is not filled with soil or when the filling is not more than 500mm.
