Large construction projects, before they begin to erect them, are tied to a land plot on which construction is planned. The geological exploration of land plots is carried out, the type of soil, the mobility of its layers, the presence of landslides, groundwater and their level are determined. If there is an old documentation regarding the geological exploration of an earlier time, then they are compared with each other and experts give an act of conclusion.
In the event that soils have loose or there is a threat of layers, to strengthen the foundations, use the method of clogging piles or their immersion using a vibration loader. This technique is also used in places where soil consolidation is required, preventing them from sliding on embankments, slopes and in a populated area where landslides are observed. Not every construction company can purchase equipment with which piles are installed, this also applies to vibration loaders. To carry out the work of the company, they take a vibration loader for rent from those enterprises that can afford this type of activity.
The principle of operation of the vibration loader is based on the vibrational moment, which is aimed at vertical immersion of piles in the soil layers. Previously, the pile is buried to a small depth in the soil, the upper part is fixed on the vibration loader head. The maintenance personnel determines the vibration moment required to immerse. At low vibration frequencies, piles will not be able to delve into the ground, and with very large it can break it off, so it is necessary to make the correct calculation. The lease agreement is concluded in the usual procedure: the validity of the contract, the conditions of the operation of the mechanism, the conditions of maintenance personnel and financial payment are indicated. If the contract requires extension, the lease agreement is extended.
