The treatment is effective in the top layers typically up to 6m depth, though improvements up to 10m have been seen in some conditions. A drop weight of 5 to 10 tonnes (depending on size) is dropped onto a special foot assembly 30-80 times a minute. The foot remains in contact with the ground at all times.
Rapid Impact Compaction is a compaction machine that uses the combined force of machine gravity and variable force to compress soil. The compaction method of soil by Rapid Impact Compaction can be called "dynamic compaction method" for short. High speed refers to high hitting frequency. Rapid Impact Compaction is evolved from hydraulic pile hammer, which naturally has several technical advantages that hydraulic pile hammer is difficult to replace. In the future, the compactor is mainly used for reinforcement when building roads. It should be able to uniformly improve the compactness of the soil without damaging the overall structure of the soil, so as to improve the overall bearing capacity and stability of the soil. The influence depth is no less than 1.5m of the 25KJ impact roller, so that it can be used together.
The Rapid Impact Compaction can deal with the foundation of the area where the existing large-scale compaction or tamping machinery cannot approach, such as the back of the abutment, the side of the culvert, the periphery of the pier, the slope, the turning area of the compaction machinery, the area without road, etc., and solve the common problems such as the early destruction of the pavement after the partial foundation sinking of the main facilities such as the expressway, the jumping of the abutment, the skew of the pier and the sliding of the slope.
The Rapid Impact Compaction uses the principle of dynamic compaction technology and special design to tamp the foundation at a specific depth. The relevant research and test results show that the Rapid Impact Compaction has a large action depth, a one-time backfill depth of 1 ~ 4m, strong mobility, and can adjust the compaction energy, which is especially suitable for the compaction requirements of small areas. It fills the gap between the traditional surface compaction technologies such as rolling and vibratory compaction and the traditional dynamic compaction technology, and has a good application prospect in the construction environment such as abutment backfill. Today, I will introduce the characteristics of hydraulic tamping machine.
1. The Rapid Impact Compaction is directly installed on the loader or excavator, and it is flexible, and the corners do not need to be treated with small tamping machines and tools alone;
2. The action depth is large, and the one-time backfill can be 1 ~ 4m, which greatly improves the construction efficiency;
3. Reduce the input of small compaction equipment and manpower, reduce the repeated utilization rate of compaction equipment, and greatly reduce the construction cost;
4. The Rapid Impact Compaction has soft effect, strong and uniform penetration ability, and it is not easy to form surface hardening in the treatment of base course, so it can obtain more uniform compactness in a large depth range.
