Problems solved by technology

[0004] In order to solve such a problem, a method of constructing a basement in a completed building has recently been proposed, however, since another complicated structure for supporting the building is installed in the lower part of the building, the following problems arise , that is, not only its structure is complex and the cost of setting is extremely high, but also the increase in man-hours leads to the extension of the construction period, and in addition, the project cost is increased due to a large amount of manpower input

Embodiment Construction

[0037] Hereinafter, the construction method of the basement of the completed building according to the present invention will be described in detail with reference to the accompanying drawings.

[0038] The present invention can adopt a simple and safe method to build or add a basement in the case that the completed building has no basement, or the basement is insufficient and needs to be added.

[0039] The construction method of this basement adopts the following method to be able to carry out multi-storey basement construction, that is, a single ground pile is pressed into the foundation suitable for the ground of the completed building in a stacked manner to form, and the multiple pillars are used to support the basement. Excavating the lower foundation of the completed building in the state of the completed building to construct an underground space, pouring the bottom of the underground space with concrete to construct the basement floor, and after continuing to excavate ...

Abstract

Disclosed is a construction method of a cellar for a building completed. The construction method includes fixing supporting structures to bottom concrete of the building; installing a press-in machine on the supporting structures; inserting posts for supporting the building into the foundation under the building by inserting hollow piles into the holes to then insert the piles into the underground using the press-in machine, stacking new piles on the inserted piles, and sequentially inserting the piles using the press-in machine; excavating a foundation under the bottom concrete of the building to prepare an underground space when the building is supported by the posts; and placing the concrete on the horizontal and vertical faces of the underground space prepared by the excavating the bottom concrete of the building.

Description

technical field [0001] The present invention relates to a construction method of a basement of a completed building capable of excavating the foundation of the lower part of the building while maintaining the original appearance of the completed building for the construction of the basement. A construction method for the basement of a completed building, that is, a press-in machine is installed in a support body fixed through the base concrete of the completed building, and hollow ground piles (pile) are pressed in a row by the press-in machine. After the formed pillars safely support the completed building, excavate the foundation of the completed building to selectively form an underground space, and pour concrete into the bottom surface of the underground space to form a basement, thereby enabling simple and safe construction of the basement. Construction, and can be constructed in a small space with low noise and low cost. Background technique [0002] In the case of a ...
