bored foundation - a kind of pile foundation.Piles as a basis for the construction of the building is used where a conventional device buried foundation is problematic: on the moors, in areas with a very high water table, or on slower moving soils with a very deep bedding of solid soil layers.The name of the foundation was bored through execution technologies: piles perform the method of pouring concrete holes drilled in the ground.

Advantages and scope

The advantages of bored foundations include:

  • possibility of building in areas with weak and strongly heaving soils;
  • low cost of operations;
  • Short terms of implementation of the foundation;
  • Low labor input and the ability to perform the foundation bored with their own hands without the use of specialized equipment.

Disadvantages include the inability arrangement basement and insufficient insulation of the lower part of the building.

Application of bored foundations - private low-rise construction lightweight: frame and wooden houses, saunas, gazebos and garages, country houses made of light materials.Bored with the foundation joists (raft) can withstand more severe stress.It is also advisable to choose the type of foundation for construction in areas with a large height difference.

design

bored foundation design is very simple: in the soil using a drill make hole depth of at least 1.5 meters.The diameter of the holes is determined by calculation and is in the range of 15-40 cm. The walls of the wells, if necessary, reinforce the formwork, install reinforcement that prevents the vertical deformation, and pour concrete.On top of piles depending on the type of structure stacked gratings or immediately erect walls.

technology implementation

Perform project containing the calculation of the amount, depth and diameter piles.Make a plot layout: define the axis of the future building, choose the first corner and hammered into his metal bar.To rods tied twine, and using the protractor lay perpendicular to the two adjacent walls.Having measured the outer distance mark the second and third corners, and with the help of string and inclinometer define and mark out the fourth corner.Sweep the walls on the current distance mark the places of drilling.

With the help of special equipment or hand auger doing well, their depth and diameter are determined by calculation.At the same time to carry out a more solid foundation for using the drill, having at the end of the plow, and expand the base of the wells allows for the formation of extension support.When drilling by hand use a level tied to the drill - drill compare their position after each turn and align if necessary.

The process of manual drilling for the foundation

When drilling the soil crumbles - performing formwork.The easiest way of providing besides waterproofing - roofing material, folded on the diameter of the hole.Also, the casing can be made from a rather narrow planks or cement pipes.

Perform reinforcement piles with vertical bars settlement section.Rods must be connected at some distance from each other by transverse rods, wires connecting them.If you plan to blow grills, rebar output on grillage height for the best binding structures.

The process of reinforcing the foundation

process of reinforcing the foundation

the prepared hole with the formwork and pour concrete reinforcement of the brand is not below 200, what brand of concrete needed for the foundation of search on a site.To remove voids valve lift within the well several times.If the technology is used with the expansion of foundation piles, the concrete formwork after the first portion of the fill must be lifted to 20-30 cm, which will complete the concrete pile foundation.

further construction at such technology performance foundation can begin within a few days.Piles necessarily waterproofing roofing felt or bituminous mastics in order to avoid the destruction of the foundation.

Also, in addition to the above, read about the insulation of the foundation with his own hands.
