Need For Selecting Bored Tavernier Piling For The Foundation

Another name for bored Tavernier piling is the drilled shaft. This refers to one type of concrete, reinforced foundation that is used for supporting structures having vertical heavy loads. This is a concrete cast-in-place type of pile, where there is casting of pile on a construction site. It is different from other type of concrete foundations such as square reinforced concrete pile, and a spun pile foundation. It makes use of concrete precast pile. It has a common use in construction of tall buildings, huge industrial complexes, and bridge work requiring a deep foundation. Installation of bored Tavernier piling begins by drilling vertical holes in the soil.

This process makes use of piling bored machine and it is possible to outfit this with especially designed tool for drilling, buckets and it grabs for removing rock and soil. It is possible to drill the pile to maximum 60 m and maximum 2.4m diameter. Drilling process often include driving steel temporary sleeve or cylinder into soil. It remains in its place within upper hole portion until there is pouring of the pile. Upon the drilling of the hole, there is building of reinforcing rebar steel structure, lowered into hole followed by the filing of the hole with concrete.

There might be capping the Tavernier piling top with pier or footing near the ground level for supporting structure above this. Bored pile work is extremely specialized operation that requires extensive experience and knowledge of bored piling engineering and construction along with site and soil conditions.

Applications of the bored pile

Used in the foundations this type of piling remains specified for the buildings or other structures imposing thousands of tons in load. It remains well suited for difficult or unstable conditions of soil. Besides the foundation system, the use of the bored Tavernier piling is in creation of underground structural walls for the earth retention purposes. It is possible to place the piles close together where the gap between piles is 75-150mm. The name for this is contiguous wall and you can place this in a way to facilitate overlap.

It helps to create pile secant wall used for the controlling of groundwater migration.

The challenges involved

Similar to the other foundation deep systems, the bored piles also pose certain challenges to the contractor. There the method of drilling depends upon soil type so it is necessary to complete thorough investigation of soil and report. Piling contractor is going to rely upon the report along with past experiences for choosing appropriate drilling method to minimize surrounding soil disturbance. With zero cohesion of soil, as with gravel, silt, and sand, or hole extending under water table, it is necessary to support the hole using stabilizing mud or steel cages as the bentonite suspension.
