Vibrators are used on construction sites. This device is used to immerse reinforced concrete pipes, piles, wells in sandy or clayey soil. On the bank of a river or near another body of water – the vibrator is especially useful, so it is excellent for installations of hydraulic structures, such as wharfs, bridges, storm sewers, ports, and so on.
Pile vibration loaders are working on the principle of reducing resistance when immersing piles under the influence of vibration. Such machines create the vibration of the soil, which makes it possible to easily load or extract pile elements. The work on loading piles into the soil is carried out not only with the help of a vibration loader, a vibration isolator and a lifting device (crane, copper, excavator) are required in the pair. Depending on which device the vibration loader will work with, the model of this machine is selected.
The vibration loader has different captures, which are determined in accordance with the purpose of the work. So, the standard capture is used to immerse Larsen’s spont, as well as pipes with a diameter in the interval of 260-410 millimeters. If the piles are smaller diameter, then the headman for pipes is used. Double capture of pipes in a vibro -loader are used for piles with a diameter of more than 420 millimeters.
There are vibrators with normal frequency and high frequency, as well as non-resonant models. The first option is good for immersing the slopes and profiles. Heavy materials are easier to immerse with the vibration loader of a normal frequency. The high -frequency vibro loader has a reduced transmission of vibrations to the soil, a steady static moment, increased performance, a low number of moving parts. Rightless vibration loaders of piles have the ability to adjust vibration force. Noise level from such machines is low.
The use of the vibration loader is due to the fact that the cost of immersion of the piles is reduced and this is quieter in the sound parameter than if the work is done with piles.
