Abstract

The invention relates to a method for excavating a foundation pit in situ under an existing preserved building and adding an underground structure. According to the positional relationship between the ground work site required for the construction of the new foundation pit and the existing preserved building, the jacking and underpinning building and the in-situ underpinning building are respectively determined, and the jacking and underpinning structure is constructed under the jacking and underpinning building. The in-situ underpinning structure is constructed under the in-situ underpinning building; after the jacking up underpinning building is lifted to a preset height, the supporting structure set on the lower surface of the jacking up underpinning structure and the jacking up underpinning structure together form an overhead structure. A large construction space is provided under the structure, which is convenient for the construction of the deep foundation pit enclosure structure and the construction of the deep foundation pit next to the building, and the underground structure is set in the main body of the formed foundation pit. The invention is suitable for foundation pit construction and underground space development under the existing preserved buildings, without causing damage to the existing preserved buildings, and does not require a large site around the original site of the building for construction, and the construction difficulty and cost are significantly reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for excavating a foundation pit in situ under an existing preserved building and adding an underground structure. Background technique [0002] Existing preserved buildings (including historically preserved buildings, cultural relics buildings, buildings in protected areas and other types of buildings that cannot be demolished) are important carriers of urban history, art and culture, and thus have received more and more attention from urban managers; With the development of the city, the underground space has also been more fully developed. In the development and construction of modern urban underground space, attention should be paid to the organic combination of existing preserved buildings and new underground structures, so that the old preserved buildings can use the development of underground space to improve their use functions and adapt to the needs of the de...
