Rapid Impact Compaction is a kind of pavement compaction equipment, which is mainly used for the back of abutment, culvert side, around pier, slope, turning area of compaction machine to machine, no road area, etc. it can better solve the common problems such as early rise damage of roads after partial subsidence of important facilities such as expressway, bridge abutment jumping, pier inclination, slope sliding, etc. The influence depth of Rapid Impact Compaction depth about 1~10m. According to the R & D and production technology of each manufacturer, the influence depth will also be affected.
Rapid Impact Compaction is a kind of pavement tamping equipment developed in recent years, which is mainly suitable for the compaction of bridgehead and narrow pavement, and is suitable for the compaction of bridgehead and narrow pavement. It has the advantages of high tamping energy, high efficiency, convenient transition and so on, and effectively solves the phenomenon of "abutment bump" caused by the uneven settlement of the subgrade at the junction of abutment and pavement.
Hydraulic rammers can be divided into two types: single acting and double acting according to the falling mode of rammers. The single acting hydraulic compactor uses a hydraulic cylinder to lift the compactor to a certain height, and then the compactor falls in a free fall manner, transforming the gravitational potential energy into kinetic energy. The compactor tamps the foundation by impacting the tamping seat with cushion. In the process of falling, the rammer of the double acting hydraulic rammer is affected by gravity and hydraulic pressure. Therefore, the rammer falls at a speed greater than that of the free falling body, so that the rammer can obtain greater impact energy to improve the impact compaction effect. As a working device, Rapid Impact Compaction can be installed on hydraulic excavator and loader. The power source of hydraulic system and circuit comes from excavator and loader.
The compaction site is usually an arc with the excavator or loader chassis installed with a Rapid Impact Compaction as the center of the circle. The center spacing of the real-time tamping points of the first tamping is about 2m. When the tamping point is fully tamped, it can be selected to overlap in the middle of the first tamping point. After the construction of Rapid Impact Compaction is completed, the site can be further leveled by road roller. Although the Rapid Impact Compaction is smaller than the word tamping equipment, the high-speed tamping frequency of the Rapid Impact Compaction is completely beyond you. The tamping energy of weapons per unit area is higher, and the foundation improvement effect is better.
According to the research, the dynamic compaction technology adopted by the Rapid Impact Compaction fills the gap between the traditional surface compaction technology, such as rolling, vibration compaction and traditional dynamic compaction technology. The normal compaction depth of the Rapid Impact Compaction can reach 4m, and the influence depth can reach 10m. The compaction depth is more than ten times that of the traditional compaction technology, and three to four times that of the impact compaction technology. It is especially suitable for rapid compaction of the foundation with a depth of 3-10m.
