Method for building basement on existing building/structure

Abstract

The invention relates to the technical field of building construction, in particular to a method for building a basement on an existing building / structure. The method comprises the following steps that 1, soil around supporting piles on the outermost periphery of the lower part of the building is cleared out, and the supporting piles are completely exposed; 2, the supporting piles on the outermostperiphery are reinforced, concrete is poured after reinforcing, and thus an external wall is formed by the supporting piles on the outermost periphery; 3, the soil in the external wall is removed, thus the supporting piles in the external wall are exposed, and the height of the cleared-out supporting piles in the external wall is the same as the height of the supporting piles on the outermost periphery; 4, reinforced concrete is poured at the bottoms of the supporting piles in the external wall to form a bottom plate, and the bottom plate is connected with an external ring to form a whole; 5,the supporting piles on the key combined points are reinforced; and 6, other supporting piles are removed. Through the method, the basement can be built on the lower part of the existing building / structure without affecting the existing building / structure, and the utilization rate of the existing building / structure is increased.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for building a basement on an existing building / structure. Background technique [0002] At present, some newly-built buildings will use the underground space to build basements or underground garages. However, some older buildings do not have basements underground. Because there are a lot of support piles distributed at the bottom of existing buildings, it is necessary to It is a very difficult project to build a basement on an existing building or structure, and there is no document disclosing such a method at present. However, with the continuous shrinking of the above-ground space in cities, rational use of the underground space of existing buildings will be the development direction of the construction industry. Contents of the invention [0003] The object of the present invention is to overcome the deficiency of above-mentioned technology, and pro...
