Huge high-rise buildings in modern cities are striking in their beauty and sizes! Their weight can reach up to 200-300 thousand tons. Such a huge burden to have to withstand the Earth! It is necessary to study the underlying rocks, which the constructors are called primers.
To study the properties of soil digging wells. But sometimes, especially in sandy soils below the groundwater level, or who are in loose condition), only the results of drilling, it is difficult to identify geological conditions at the site. In such cases, resort to such methods surveys, statistical and dynamic sounding, when the properties of soils are determined in situ. Let us consider in more detail the method of sensing.
Geology of the land includes field and laboratory testing of soil. Field have more advantages, as it gives the opportunity to explore the soil directly on the ground in their natural state. Sensing of soil allows to determine the density of soil, its composition, the resistance of the soil under the pile, depths of soil, and more. This test is performed with special geological equipment, allowing to carry out the indentation of the probe into the soil. The depth of the indentation may be different from 5 meters and above, it all depends on what the building or structure will be built (for example, if you plan some kind of lightweight construction, it is sufficient depth of 6 meters). Originally performed drilling and only then the dense layer to a depth of three meters probe is installed.
the General sequence sensing is as follows: the probe is evenly pressed with fixing every 20 cm of ground resistance to indentation. Also it is possible to commit data by writing on chart paper tapes, which is carried out automatically. Build next link of rods, lift the rod of the Jack in the up position until, until you reach the desired depth is reached or when pressure on the probe or cone.
When processing the data tested is initially determined mean value for a particular geological layer for single point sensing. Then there is the arithmetical average value of all pixels of the plot. The obtained data can be used to calculate the bearing capacity of different types of piles with defined cross sections.
in Addition to sensing the ground you can also die succumb to the test. This method allows to determine the susceptibility of soil to compaction. Die testing ground is used when it is planned the construction of buildings or structures having a normal and an increased level of responsibility. This test gives more accurate information about the properties of the soil, than laboratory studies. During die testing ground experience with a special stamp. Sand, clay and prone to shrinkage of the soils should be subject to a test of the stamp. The essence of this method: on the ground to create a load that is comparable to the load of the building or structure that is being designed.
