Application principle and characteristics of Rapid Impact Compaction

Product Overview

Rapid Impact Compaction is also called high-speed hydraulic tamping machine, etc., with convenient transition, high maneuvering efficiency, greatly improving construction efficiency, so it is called mobile high-speed hydraulic tamping machine, Evergrande rammer god high-speed hydraulic tamping machine manufacturers mainly develop, produce, sell HC series high-speed hydraulic tamping machine, High-speed vibration tamping machine, high-speed hydraulic pile hammer and other pavement tamping equipment, with independent R & D production capacity, strong production strength, strong R & D team, perfect pre-sales and after-sales service, welcome to inquire.

As a safe and environmentally friendly Rapid Impact Compaction It is composed of rammer hammer, ramming frame, rammer plate, hydraulic drive device, etc. The technical principle is: the rammer hammer is lifted to a certain height with a hydraulic cylinder and released. The rammer is accelerated by the combined action of gravity and hydraulics. Trail behind, hit the ram plate with cushion, statically press on the ground, and then tame the ground through the rammed board. Since the ramming hammer on the ground is implemented by ramming plates with cushions and static pressure on the ground, compared with the traditional tamping technology, compared with the continuous action of the Rapid Impact Compaction, its force peak is small, the action time is long, the function is soft, it is not easy to cut and fill the streamline, and it has the functions of dustproof and splash-proof. Compared with the traditional surface rolling technology, its penetration is strong and uniform, and it is not easy to form a surface harden in the basic treatment, which can obtain a more uniform density in a large depth range. As a general-purpose Rapid Impact Compaction, in order to have a straight ramming structure without rammed plates, the ground mechanism of action has a large compaction strength with the traditional compaction technology (strong ramming, etc.), and can also be used to crush the ground and other structures.

The Rapid Impact Compaction has been rigorously tested and verified at many construction sites. According to the results of the field test, it has the following application characteristics:

(1) It can realize the overall compaction of the thick fill layer, improve productivity, reduce or avoid the phenomenon of interlayer slip and separation that may be caused by the layer compaction technology. After the thick layer is compacted, the compactness can be evenly reached by more than 96%.

(2) The Rapid Impact Compaction can handle the foundation of the existing large compaction or tampling machinery such as abutment back, culvert side, bridge pier periphery, slope, compaction machinery folding area, roadless area, etc., and solve the problems of early damage to the pavement after the sinking of the local foundation of common highways and other important facilities, abutment jumping, bridge pier skew and slope slippage.

(3) River embankments can be strengthened. The current soil embankments constructed and reinforced by small and medium-sized compaction mechanical layer compaction technology are virtual on the middle and solid sides, and it is impossible to solve the problem of soil layer infiltration and slope collapse at large flow rates. Rapid Impact Compactions help solve this challenge. Its variant, the Universal Tamping Machine (Straight Rammer), helps to truncate pipe surges.

According to the different construction requirements, the Rapid Impact Compaction can carry out a variety of tamping operations such as plane tamping, step tamping, groove pit tamping, inclined tamping, etc.; The Rapid Impact Compaction can be used for road surface and site crushing after modification of the breaker; Safe and environmentally friendly Rapid Impact Compaction can be used for piling when necessary.
