Different types and methods of work can be used to summarize the foundations. Most often, if soil and hydrological conditions allow, the summing up of new foundations is carried out in the form of separate supports in mines, followed by their filling with masonry. The dimensions of the mines in the plan are determined by the calculation of pressure on the base. This type can be recommended and very often used in cases where the device of mines (wells) will not require significant drainage, which can cause suction of soil particles and harmful sediment of neighboring buildings.
With ground strata, poorly giving water, where the use of artificial decrease will not give the required effect on the planned time, from the device of supports in individual wells (mines) should be refused.
In the latter case, it is advisable to use piles, which will transfer the load from the structure to the more strong ground layout.
In addition to these two techniques in dry sandy coarse -grained soils, soil consolidation can also be recommended by injection of chemicals or cement milk
In cases where the presence of groundwater makes it difficult to penetrate the mines and there are cobblestones, the remnants of old piles that make it difficult to drill for stuffed piles are found in soil strata, shell -on -shelves and even caissons used to eyeliner foundations. However, in modern practice, with complete mechanization of drilling operations, it is possible to give the indicated obstacles, and it will be much cheaper and safer for the updated building and workers to use stuffed piles.
When eyeliners, two phases of work occurred: auxiliary work and main work. The first includes the production of all kinds of temporary struts, beams, etc. to give the construction of the necessary stability during the work of work.
The main works include mining, laying the foundation itself and jamming it with the sole of the existing foundation.
