Method and system for local translation correction of large chassis structure

Abstract

The invention provides a method and system for rectifying partial translation of a large chassis structure. The position where the displacement deviation of the large chassis structure engineering is detected is defined as a pre-cut structure; the structural main bodies on both sides of the local translation pre-cut structure of the large chassis structure are supported; through limited The element software simulates and calculates, and strengthens the main body of the structure; introduces the historical monitoring data of the site as the initial condition into the finite element calculation software, and arranges new dynamic monitoring measuring points for the main body of the structure; performs stress release on the soil on the other side of the translation , to form an operable space for underground horizontal pushback; cut off the connection between the pre-cut structure and the main body of the structure on the vertical plane, and become a free and independent rigid body that can be pushed; install horizontal graded loading on the translation side of the free independent rigid body The device applies an external force to move a free and independent rigid body; after the movement is completed and reaches a stable state, the structural main body of the cut structure is repaired. After the repair is completed, the soil is backfilled and the deviation correction is completed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a building deviation correction method and system. Background technique [0002] In the construction of construction projects, it often occurs that due to the construction line error, or the local displacement deviation of one or several buildings in the large chassis buildings during the construction of surrounding houses, the change of the structural stress system affects the structural bearing capacity. At present, The object of translation of the building is the overall translation, the structural system is relatively simple and single, and the force system hardly changes. To perform the overall translation, a large amount of labor is required to act on the jack at the same time, and the labor cost is very large, and there is a slight Inadvertently, an irreversible situation may even occur, resulting in safety accidents; for example, the patent document CN110185...

[0002] In the construction of construction projects, it often occurs that due to the construction line error, or the local displacement deviation of one or several buildings in the large chassis buildings during the construction of surrounding houses, the change of the structural stress system affects the structural bearing capacity. At present, The object of translation of the building is the overall translation, the structural system is relatively simple and single, and the force system hardly changes. To perform the overall translation, a large amount of labor is required to act on the jack at the same time, and the labor cost is very large, and there is a slight Inadvertently, an irreversible situation may even occur, resulting in safety accidents; for example, the patent document CN110185076A applied for by China discloses a method for reinforcing and correcting deviations of existing buildings. Positioning, positioning the pile position on the axis according to the design, and numbering each pile position; proofreading, proofreading one by one according to the numbered piles, and confirming the pile position after repeated proofreading; excavation, vertical first according to requirements Excavation, then oblique excavation to the bottom of the foundation, and then vertical excavation; acceptance, stop when the excavation reaches the design depth, and pass the acceptance of relevant personnel until the required depth is reached; the first formwork, according to the design needs Formwork, And, place the reinforcement cage in the template; for the first pouring, pour concrete between the prepared templates, wait for it to form a bottom pile, and pre-embed the steel head
