Secondly, this paper made some theoretic researches on its engineering classfication and applicable scope for this technology ; then combining with project example, this paper carried out scheme design for this technology, and compared some different kinds of underpinning scheme and node and structure design, and put forward the method of " reinforcce steel bar through column " to build pile cap beam, " resistant bend and shear anchored reinforce steel bar " to strengthen column consolidation effect, and the method of " steel plate hoop " to build reinforcing bar connection of the foundation beam, etc. in the process of the consturction scheme research and implement, this paper synthetically elaborated the organizaton for project construction, put forward the construction technical measure of specific aim on the artificial pile, and pile cap beam, and underground adding layer and structure stabilization, and overall structure stabilization and so on. for this project, adopt reinforcing bar concrete to brace hole wall to ensure the safety of engineering in the artificial pile construction, use flexible connection catch to make the cage hoisting easier to simplify the construction process, use the method of earthwork statified symmetrical balance in the process of underground adding layer excavation
本文首先對于基礎托換與結構加固技術的目的和意義、國內外發展狀況進行了綜合闡述;其次對該項技術工程分類及適應范圍進行了理論上的分析研究;然後結合工程實例對該項技術進行了方案設計,對比幾種不同的托換方案和節點及構造設計,提出了「通筋穿柱法」做承臺梁, 「抗彎抗剪錨筋法」強化柱加固效果, 「鋼板箍法」做地基梁鋼筋連接點等多項技術;在施工方案的研究和實施過程中,對于工程施工組織進行綜合闡述,並就人工
