Benefits of technology

[0020]The structure construction method according to the present disclosure has the following effects.
[0021]First, an excavation wall and an outer wall, which are the structures of an underground structure, may function as a structure, while being used as earthen barriers during the construction process. Accordingly, soil leakage and water may be prevented in the vicinity of new construction, and thus the safety of nearby facilities may be secured.
[0022]Second, when the conventional method is used, groundwater leaking during excavation is discharged through pumping, which lowers the surrounding groundwater level, thereby producing a sinkhole and causing a safety related problem to adjacent structures. On the other hand, according to the present disclosure, the groundwater is not discharged out, but excavation is performed using a w

Problems solved by technology

In constructing a basement floor on a ground with a high level of groundwater or soft ground, the outflow of groundwater may cause serious damage to not only underground structures such as adjacent tunnels, box structures, and subways, but also ground structures.
However, in actual construction, even life-threatening accidents frequently occur due to the collapse of the earthen barrier or the like.
In addition, adjacent structures or roads undergo cracks, differential settlement, and sinkholes.
In recent years, even at excavation sites where the excavation depth is not relatively deep, which is not the target excavation depth, the collapse of an adjacent building has occurred due to the collapse of earthen barriers or the outflow of groundwater.
As such, excavation for the construction of underground structures in urban areas is a very difficult task.
The conventional underground structure construction method for constructin

Example

[0056]FIGS. 2 to 7 show the first embodiment of the present disclosure for constructing the underground structure 100. Hereinafter, each construction step in the case of constructing the second basement floor will be described in detail with reference to FIGS. 2 to 7.

[0057]① Construction of the Foundation Plate 10 (See FIG. 2).

[0058]A foundation plate 10 made of reinforced concrete is constructed on the ground. As shown in FIG. 2, the edge of the foundation plate 10 may be directly adjacent to the land boundary line 400, or may substantially coincide with the land boundary line 400.

[0059]In the construction method, the outer wall of the underground structure is used as an earthen barrier. Accordingly, a separate earthen barrier is not required. The foundation plate and the outer wall of the underground structure are constructed so as to contact the land boundary line as much as possible to maximize the underground space.

[0060]First, since the foundation plate 10 is constructed, and ...

Example

[0094]In the second embodiment, the pile 20 is first constructed, and then the foundation plate 10 is constructed. In other words, in the second embodiment, step ② is performed first, and then step ① is performed. Then, steps ③ to ⑦ are performed as described above.

[0095]In the first and second embodiments, the process of forming the first basement structure and the second basement structure has been described. However, the present disclosure is not limited to the first basement structure and the second basement structure. That is, only the first basement structure may be formed, or a plurality of basement floors of two or more basement levels may be formed by repeating steps ④ and ⑤ described above.

[0096]FIGS. 10 and 11 illustrate construction of an underground structure 100 according to a third embodiment of the present disclosure.

Example

[0097]The third embodiment may be applied when an area where an underground structure is constructed is large. That is, when the plan area of the underground structure is large, forming the entire foundation plate as one body and sinking the same may be difficult and have a risk of damaging the foundation plate, and may be rather inefficient.

[0098]In this case, an outer foundation plate 50 is constructed for a certain width at the land boundary line 400. Then, the outer foundation plate 50 is sunken in the same manner as described above. An outer basement structure 60 may be constructed on the outer foundation plate 50 and then sunken. In this operation, while excavating the soil under the outer foundation plate 50, the outer foundation plate is sunken. Once sinking of the outer foundation plate is completed, a foundation plate and the basement structure are constructed.

[0099]At this time, the internal soil inside the outer foundation plate 50 may be left as it is. Then, the interna...

Abstract

The present invention relates to a method for constructing a structure, the method comprising constructing an underground structure on the ground, and then constructing the structure in the ground by sinking same into the ground.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a method for constructing a structure, and more particularly, to a method for constructing an underground structure above ground and sinking the same into the ground, rather than installing the same underground.BACKGROUND ART[0002]In constructing a basement floor on a ground with a high level of groundwater or soft ground, the outflow of groundwater may cause serious damage to not only underground structures such as adjacent tunnels, box structures, and subways, but also ground structures.[0003]When excavation is performed beyond a certain depth, the safety of adjacent structures is partially checked before construction through the excavation depth or the like. However, in actual construction, even life-threatening accidents frequently occur due to the collapse of the earthen barrier or the like. In addition, adjacent structures or roads undergo cracks, differential settlement, and sinkholes.[0004]In recent years, even at excava...
