Research Of The Wood Piles Applied In The Foundation Teatment For The Middle Of Walking Of The Building Monolithic Movement

The technology of building monolithic-translation afferent into China in the 20th century the 80's. In recent years, with China's large-scale urban construction, the technology developed rapidly, especially over the past decade, development has been mature.The technology of building monolithic-translationg widely used mainly of the meaning of avoiding the demolition and reconstruction of existing buildings, investment saving, environmental protection, an successful settlement of the conflicts between modernization construction and conservation, reflecting a very good social benefits.During the project of building translation, the foundation treatment for the middle of walking is very important., it is directly related to the safety and the cost and the cost of the whole project. With the conventional treatment of the foundation of comparison, the foundation treatment of the middle ground has the following characteristics:â‘ Short-term load. In the ranslation process, the buildings remain in the middle, shorter paragraphs, the settlement can be seen as instantaneous settlement.â‘¡Temporary. This part of the foundation cannot be re-used after the translation.â‘¢Small. Need to be addressed in a less inconvenient for large-scale machinery into play.â‘£Small venues. Most translation projects in the city, even downtown, is more sensitive to vibration, noise and environmental pollution are also more restrictions Based on the above points,the wood piles become a very good choice for this kind of project.The based project of this paper is located in the coastal areas of Tianjin, is a typical soft soil earain coastal areas, there are thicker due to the consolidation of the marine deposit of silt and silty clay layer, which is characterized by high mositure content, low strength, large porosity, high sensitivity, clear structure effects. Taking into account the creep characteristics of the marine soft soil, making full use of its structural strength with wood piles.Judging from the data collected during the ranslation process: during the ranslation process, the settlement of the location floating up and down with the colume one by one after, the overall trend was gradually increased, reflecting the structural and creep properties of the marine soft soil; the max settlement fully meet the requirements of the differential settlement;Wood piles used to the middle ground segment processing, integrating theory with practice to illustrate the effectiveness and the practical of the method.
