Problems solved by technology
[0002] At present, there are many new construction projects on the basis of old buildings. Most of these projects are that the original old buildings do not meet the needs of urban functions in the new era, and need to be demolished to rebuild new buildings, or the original developers have no follow-up development. Construction capacity, the new developer who took over has made substantial adjustments to the original design of the building, and the completed part needs to be overthrown to rebuild the project

The invention discloses an obstacle removing construction method for a large-diameter underground steel concrete composite structure, which is suitable for removing obstacles of a steel pipe pile foundation, a latticed column supporting pile foundation, a pile-to-column pile foundation and the like, and is particularly suitable for removing the steel pipe pile foundation and the pile-to-column pile foundation with the diameter more than phi600. According to the method, the underground obstacles are effectively removed while small disturbance of a base soil body is guaranteed, additionally, the construction of follow-up engineering can be guaranteed, and the problem that underground steel concrete composite obstacles which are vertically distributed need to be treated in the rebuilding process of an old building is effectively solved.
Description
technical field [0001] The invention relates to the clear treatment of vertically distributed obstacles in an underground steel-concrete composite structure in the technical field of construction engineering, in particular to a construction method for clearing obstacles of a large-diameter underground steel-concrete composite structure. Background technique [0002] At present, there are many new construction projects on the basis of old buildings. Most of these projects are that the original old buildings do not meet the needs of urban functions in the new era, and need to be demolished to rebuild new buildings, or the original developers have no follow-up development. In terms of construction capacity, the new developer who took over has made major adjustments to the original design of the building, and it is necessary to overturn the completed part and build a new project. There are more or less conflicts between the pile foundation of this new project and the old pile fo...
