What is ground improvement?

Ground surveys are done before structures are constructed.

Ground surveys are done before structures are constructed. Ground data report and geotechnical report are generated in these ground surveys.  As a result of these studies, the ground conditions of the structure will be determined. After the finished architectural project, static project work on the structure and basic system is done by the civil engineer. At this stage it is seen that the ground does not meet the building loads.  Ground improvement is needed.  Many ground improvement methods have been developed. Many of these methods are as old as human history. We see that ground improvements are the basis of structures that have survived for thousands of years.  Filling, cement injection, fore piling, jetgraut cement, column, pile creation, stone column making, wood piling methods such as the common sayabilriz. 

The most widely used and vital for the construction of filling can be summarized briefly.  Ground surveying is done on the land to be constructed. Then the project is prepared.  Let’s say the ground survey saved the project. My suggestion is to fill in all conditions in the proportion of facilities. Filling is vital when the building foundation is opened.  There may be errors during the excavation phase of the construction Foundation. As follows; it was revealed that the building should sit on the unit after 1 meter in the ground survey. The project was conducted accordingly. However, during the construction phase, when half a meter of plant parts are stripped off and the foundation mold is hammered and the concrete is poured, a half meter of weak ground will remain between the solid ground and the building foundation. This is a big risk to the structure.  The foundations of the building should be excavated more than half a meter to 1 meter depending on the situation and filling should be done in the standards of highways. If possible, we have to calculate the dry unit volume weight of the material to be filled with Proctor experiment. This value is better than 2.0 gr/cm3. The unit weight of the stabilized 0-51 material is generally very good for the future of more than 2.2 gr/cm3.  It’s not enough to lay out fillers. This filling should be compressed with construction machines in a suitable wet conditions of 25 cm.  Compacted Proctor dry unit volume weight value is determined by sand cone experiment where known filling material is not well trapped. After it is determined that the proctor provides 95% of the value and above, the next step must be taken. If you do not have all these technological facilities, you find gravelly, Sandy, blocky filling material to your foundation 25 cm cool. Put a kamyok or jsb scoop on it. Then proceed as 25 cm.

Filling will reinforce the foundation of the building and will also make part of its sitting as the floor is loaded. This seating on the floor will increase the carrying power of the floor. In this way, filling will provide the necessary benefit in the structure and life Security will be provided.
