A method for reinforcing the building's overall translational foundation

Abstract

The invention discloses a method for strengthening the overall translational foundation of a building. Firstly, an operation pit is excavated around the foundation of the building, and a wire saw machine is used to penetrate the bottom of the foundation of the building step by step in the operation pit or outside the operation pit. cutting, and then use prefabricated hollow box girders to gradually replace the soil in the cut main support block, gradually replace the soil at the bottom of the entire building foundation with multiple side-by-side prefabricated hollow box girders, and then replace multiple side-by-side prefabricated hollow The two ends of the box girder are connected with the ring beam to form an integral foundation; the present invention uses a wire saw to gradually distribute and cut the old foundation soil, and then hollows out the old foundation soil and replaces it with a prefabricated hollow box girder foundation. Cutting, excavation and replacement construction process has small excavation volume and high efficiency. It will not produce large vibration shocks and large amounts of dust. The construction process will not cause damage to the buildings on the foundation. The overall strength of the foundation is high, which is more conducive to translational protection of buildings.

Description

technical field [0001] The invention relates to the technical field of overall translation of buildings, in particular to a method for reinforcing the foundation of overall translation of buildings. Background technique [0002] With the continuous development of the city, some old buildings need to be demolished or moved to facilitate the expansion of new roads and the construction of new buildings. For valuable buildings such as cultural relics, ancient buildings, etc., in order not to destroy the original appearance of the old buildings, the method of moving the whole building intact to other positions is usually used for processing. [0003] There are more and more successful cases of overall translation of buildings. The overall translation of frame structure buildings is usually to set the translation lower track at the bottom of the column, set the translation upper track on the translation lower track to support the upper building, and then cut off the frame column. ...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned traditional treatment methods before building foundation reinforcement usually use manual hammering, mechanical hammering, pneumatic picks, hydraulic breakers, etc. to dismantle the old foundation. These traditional methods require a large amount of excavation during the construction process. Low, while direct penetration of slotted steel into the old foundation for reinforcement will generate large vibrations, which will easily cause damage to the building during the construction process, which is not conducive to protecting the quality of the building as a whole
