Inquiry On Optimal Design Of Soil Cement Mixing Pile

Soil cement mixing pile design principle is the use of cement (or other similar materials, such as lime) as the curing agent, through a special mixing machine, to a certain depth range (usually 10 to 20 meters) to soil and cement curing agent forced mixing, solidified to form a seal and impermeability of concrete piles a certain intensity, and with the shared pile upper soil load. The new method has been widely used for housing civil engineering, underground storage tanks, flood water storage dams, road works, railway works and the pit enclosure soft handle, and sometimes also used in the water curtain and other types of engineering, and in these engineering practice has played a significant role. With the rapid development of modern mechanical industry, improving the pile by pile process, and thus the advantages of soil cement mixing pile also expressed more and more prominent. Cement is generally believed that the advantages of such a pile points:â‘ use of soil cement mixing pile bearing capacity of the soil itself, which in principle is better to pursue engineering in general the state, so that full use of natural resources;â‘¡cement mixing pile in ground handling construction of the original soil structure disturbance is relatively small, while the design and construction of the entire structure has also played a role in ensuring good;â‘¢concrete piles in the financial characteristics of savings is their wide application of one of the reasons. But with the increasingly complex engineering structures and large numbers of high-rise buildings, the upper structure on the foundation and the basis of higher and higher demands, soil and water to some extent as a composite foundation can play a role, but also the design and construction difficulties continues to increase:â‘ the excavation depth increases, the current situation from the current use of concrete piles supporting the structure as the depth has also been a clear limit, which makes cement mixing pile obvious flaws exposed;â‘¡cement mixing pile itself is cement and soil physical and chemical reactions through the formation, and thus its nature (mainly the deformation of pile compressibility) are not as stable as a single physical structure, its strength is only between body between the soil and cement, often reach the intensity of drawings, which now works in response to soil-cement pile of these shortcomings, by adding a variety of structures or structural measures to improve the strength of concrete piles.Articles in understanding the basic nature of the soil cement mixing pile and applications based on the content through the chapters of their physical and mechanical properties and design method for further study. In discussion of the process, the article put emphasis primarily on the method of design, don't focus on the discussion, in main content will closely adhere to these main lines, try to improve the design and construction on new ideas and to study its feasibility, and in the final instance to reflect through the design of optimal design ideas and implementation process.
