Influence of blankets bore pile on soil characteristics irradiator gamma merah putih of serpong

in determining the planning of a building foundation there are two things that must be considered in the bottom soil of the foundation, namely the carrying capacity of the permitted soil and the magnitude of the foundation decline. Both of these factors determine the stability of building construction. The stress due to the existence of the building above must be able to be carried by the soil layer under the foundation and must be safe from collapse. In general, the use of pile foundation is used if the subgrade under the building does not have enough bearing capacity to carry the weight of the building and the load above it, and also if the location of the hard ground has sufficient carrying capacity to carry the weight of the building above in a very deep position. At the location of the irradiator it is known from the results of soil testing obtained hard soil at a depth of 30 m so that pile drilling is carried out to that depth. When bore pile casting is carried out it turns out that the required volume of concrete exceeds the planned volume based on BQ (bill of Quantity), so we do the pile wrapping to prevent the mix concrete from flowing out. From the results of several method changes and packaging materials, the results show that the most effective two-layer geotextile wrapper reduces concrete wastage (which functions to carry forward the burden of the building structure above it from the surface of the ground to the layer of hard soil underneath).
