Abstract

The invention discloses a method for underpinning and jacking a building and adding storeys downwards. The method is characterized by firstly forming tray structures by arranging jacketed wall beams, secondly arranging pile pressing platforms to press piles, thirdly arranging corbels to bear the load of the original building with the pile pressing platforms and the tray structures and fourthly excavating the foundation soil and connecting pressed piles by anchor rods to form a lattice column structure, thus making the storey-adding structures such as basement or making the storey-adding structures after jacking. The invention also discloses a system for underpinning and jacking the building and adding storeys downwards. The system and the method have the following beneficial effects: under the condition that the original building is not dismantled and moved horizontally, the floor area of the original building can be increased downwards in the original plane position to increase the use ratios of the houses and land so as to improve the condition of cramped room in cities.
