As you know, Forekazık is a system that is applied in areas that do not have a solid ground to transport the building loads to the solid ground. Below, there is information about Bored Pile from A to Z, based on both technical and experience.
In addition to this information, some subtle points are given about the economy-speed-cost that every Civil Engineer should know. Forekazık machines are divided into HYDRAULIC and MECHANICAL. Also some machines do not have some machines while the pipe driving feature. Therefore, our site will provide the machine under difficult ground conditions (migrating - stuck ground, hard opening wells) is required to be able to work.
Our country is located in a serious earthquake zone and after the recent earthquakes, the bored pile or other name and on-site cast reinforced concrete piles have been used more frequently. In fact, with the increase in land use and underground construction, the application of a bored pile has become mandatory. The bored pile foundation opens a deep pit with a large diameter to provide the foundation in unstable places. Concrete is poured into the pit and building foundation is secured. In addition, the bored piling machine is also useful for water extraction. Bored pile hydraulic system is used in construction industry. Particularly, the bored piles with diameters starting from 65 cm up to 150 cm are used in construction areas with low soil structure. Today, many work machines, such as bored piles, errors in the use of defective work machines, and the absence of the examination of the loss of life and property are experienced. The construction of the Bored Piles periodic checks will prevent accidents that may occur. Performing periodic checks creates a safe working area at the construction site. In this way, the building load is carried on a solid surface. Bored piles are drilling piles and their application methods are directly related to the structure and condition of the construction floor and the diameter and depth of the pile.
.
These are the piles made for the purpose of carrying the structural loads to solid grounds or for shoring in soils with low bearing capacity. These piles are bored piles and their construction methods; The condition of the site depends on the soil structure, diameter and depth of the pile. In bored piles the hole diameter can be between 50 cm and 200 cm. Bored piles, which we often hear after the earthquake, increase its importance day by day with the increase in land prices and the widespread use of underground structures. In piled piers and piers, piles can be made as steel pipe piles, reinforced concrete piles or prestressed piles. Unless absolutely necessary, sloping piles should be avoided as much as possible in docks and piers.
The most important point in bored pile application is to create a project according to the ground conditions and needs and to implement the project as specified in the relevant standards. Different materials can be used according to ground and groundwater formations, pile length and equipment capacity during drilling process. It is also necessary to use basic quality control and measuring devices during drilling operations. There are special measuring devices suitable for bored pile application. Continuity and loading tests must be performed after the calculations made during the application.
Impermeable curtain applications are made in order to prevent water entering the foundation of the ground where the ground water level is high. It is used especially in dam construction. Basic applications are used for transferring the construction load to the ground and for solution of bearing power problems. It is frequently used in the building, dam, viaduct and bridge foundations. Slope stability applications are generally used for landslide and landslide risk.
The minimum requirements for the health and safety of work machines and equipment used in workplaces are included in the Regulation on Health and Safety Conditions in the Use of Work Equipment.
As TÜRCERT, periodic controls and inspections of bored piling machines are carried out in accordance with the standards published by all organizations in accordance with the necessary legal requirements. A few standards based on this subject are:
- TS EN 12794 + A1 Precast concrete products - Foundation piles
- TS EN 16228-1 Drilling and basic equipment - Safety - Part 1: General rules
- TS EN 14199 Special geotechnical applications - Mini piles
- TS EN 1536 + A1 Special geotechnical applications drilling (forks)
