Rapid impact compaction has remarkable effect in foundation treatment construction, high tamping frequency, good compaction effect, convenient transfer, safety and environmental protection. In foundation treatment, the impact on nearby structures is much smaller than other compaction methods, and it is a good choice for basic treatment schemes such as pavement subgrade treatment, combined treatment of old and new roads, urban traffic, and landfill. Rapid impact compaction is a new type of pavement foundation compaction equipment, which is easy to transfer, high construction efficiency, and has the advantages of loader and compactor. It is especially suitable for the construction of mountain roads and narrow construction sites. It is more conducive to the compaction of weak rolling areas of large compaction equipment, and further fills the loopholes in traditional road compaction and traditional dynamic compaction technology.

Introduction to Rapid impact compaction

Compared with traditional compaction equipment, it has high compaction energy, large impact depth, flexibility and multi-purpose. In order to meet the compaction needs of different foundations, the compaction energy can be adjusted. In addition to the same model division rules, rapid impact compactors and impact rollers also have the characteristics of "compacting" and "rolling". The main feature of impact rolling is that the impact rolling "rolling" has a large drop due to its polygonal and non-circular characteristics, and has "ramming" during the construction process. Therefore, the impact strength is large and the impact depth is also large.

Rapid impact compactor as a working device, is usually installed on a wheel loader or hydraulic excavator, and its hydraulic and electrical power comes from the loader or excavator, and its support. It includes a box, hammer, hydraulic system, electrical control system, etc. The hydraulic system of the rapid impact compactor agreement mainly includes hydraulic cylinders, batteries, electromagnetic reversing valves, etc. Rapid impact compactors are supplied by a loader or excavator, so its hydraulic system and the loader or excavator are set up as a complete hydraulic system.

Precautions when the rapid impact compactor goes uphill

If the brake fails when the rapid impact compactor goes uphill, it should be reduced to the middle and low gears in time to maintain enough power to stop at the top of the uphill. If half-slope parking is required, the forward low gear should be maintained, the hand brake should be tightened, and the driver of the forklift rapid impact compactor should use stones, skids and other objects to jam the wheels in time. If there is a phenomenon of backward slippage, the rear of the car should face the hillside and the safe side, turn on the headlights and emergency signal lights, and attract the attention of the front and rear vehicles. Put down gear and pull the handbrake. According to the road conditions, control the direction of the vehicle speed, take off the high gear, quickly blow the oil, and change the high gear to the low gear. In this way, the engine of the rapid impact compactor will have a large traction resistance, which will quickly reduce the speed of the vehicle. When shifting to a lower gear, it should be combined with the handbrake, but be careful not to apply the handbrake too tightly or too slowly.

Precautions when the hydraulic compactor goes downhill

When the rapid impact compactor is going down a long slope, the brakes should be applied regardless of the situation. Check braking performance while gaining time to control speed when a braking fault is detected, also known as predictive braking. When the downhill braking fails and the vehicle's own mechanism cannot control the speed, the driver should decisively use natural obstacles to cause resistance to the rapid impact compactor. If you can't find a suitable terrain for a while, when the object can be used, one side of the body can be close to the mountain to increase the frictional resistance and gradually reduce the speed. You can also find trees and use rapid impact compactor bumpers, carriages and other steel positions to collide with natural obstacles on the roadside, so as to achieve the purpose of forced parking and minimize accident losses.

The rapid impact compactor is very large, the impact energy is up to 150KJ, and the impact depth is 1-10 meters. It is well used, so it is widely used to supplement highway embankments. Back to the bridge table to reduce filling and settlement, solve the problem of bridgehead jumping in our country, and prolong the service life of the road. Rapid impact compactors can also be used for new and old roads, oil warehouses, ports, airports, urban construction and other foundations to compact urban sanitary garbage, it is inconvenient or impossible to use rollers, impact rollers, and heavy hammers.
