Problems solved by technology
[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 so far

Embodiment Construction
[0015] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as figure 1 As shown, a method for building a basement on an existing building / structure comprises the following steps: Step 1, as figure 1 and Figure 8 As shown, the soil 3 around the outermost peripheral support pile 2 of the lower part of the building 1 is cleaned up, and the support piles are completely leaked out, such as figure 2 As shown, the height of the cleared support piles is 5-10 meters; this height is the height of the basement, and it is cleaned according to the needs.
[0016] Step two, such as image 3 As shown, the outermost supporting piles are reinforced, such as welding steel bars between two adjacent supporting piles, and then pouring concrete 4, so that the outermost supporting piles form an outer wall 5; the outer wall is larger than the original The support pile has a hi...

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...
