DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for simultaneously constructing an underground structure and an underground structure of a building in which the underground structure and the overground structure of the structure are simultaneously constructed.

[0002]

2. Description of the Related Art In the construction of a building having an underground structure and an above-ground structure, a foundation pile is usually cast in place from the ground surface (on-site ground surface), and ground excavation work is performed to the floor surface of the underground structure. It is common practice to complete the structure and then launch the above-ground structure above the underground structure.

[0003] For this reason, since the construction of the above-ground structure starts after the underground structure is completed, there is a limit in shortening the construction period.

Further, in order to suspend and transport materials of an underground structure, it is necessary to mount a crane on the ground surface and suspend the materials from the ground surface.

[0005]

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a method of simultaneously constructing an underground structure and an above-ground structure and simultaneously constructing the underground structure of a building to shorten the process. And

[0006]

The method for simultaneously constructing a building underground according to claim 1 is applied to the construction of a building having an underground structure and a structure above ground. A first step of driving a post supported by the pile,
A second step of laying floor panels on the ground surface and fixing them to the pillars, performing an earth removal operation below the floor panels and constructing an underground structure, and at the same time installing a crane on the floor panels, And a third step of constructing an object.

According to a second aspect of the present invention, there is provided a method for simultaneous underground construction of a building, wherein the underground flow line connected to the underground structure is connected to the underground structure, and the underground flow line is connected to the underground structure. And a ground traffic line for vehicle traveling at a three-dimensional intersection.

According to a third aspect of the present invention, there is provided a method for simultaneous underground construction of a building, wherein an overhead crane is provided on a lower surface of the floor panel to carry and suspend materials of the underground structure. .

[0009]

[Effect] The above-mentioned simultaneous construction method for the building above ground and underground is as follows.
In the first step, a foundation pile is driven from the ground surface, and a pillar serving as a pillar of the underground structure and the above-ground structure is erected on the foundation pile. Next, in the second step, the floor panel is fixed to the pillar while the floor panel is laid on the ground surface to complete the first floor. Since the laying of the floor panels is ground work, the work is safe and the construction period can be shortened. Next, in a third step, an excavating machine, a dump truck, and the like perform an earth discharging operation below the floor panel, and construct an underground structure sequentially from a place where excavation is completed. In parallel with this, a crane for unloading work will be installed on the floor panel, and ground structures will be started up sequentially. This enables simultaneous construction of the above-ground structure and the underground structure.

[0010] An underground traffic line on which a vehicle that carries out the excavated soil below the floor panel or carries in materials for constructing an underground structure and a material for constructing an above-ground structure are carried in. Since the ground traffic line on which the traveling vehicle travels crosses three-dimensionally, smooth operation is possible.

When the excavation below the floor panel progresses to some extent, a work space is secured, so that an overhead crane can be mounted on the lower surface of the floor panel. With this overhead crane, it is possible to suspend and transport the material of the underground structure transported from the underground traffic line, so that it is not necessary to suspend the material from the ground surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for simultaneously constructing a building underground according to the present embodiment will be described with reference to FIGS.

As shown in FIG. 1, a pile driving machine (not shown) is carried into a construction site, a hole having a predetermined depth is dug from the ground surface G, and concrete is poured into the hole, and the entire building is constructed. Is constructed to support the foundation pile 10. In this foundation pile 10, a column 12 is set up, and becomes a main column steel frame of an underground structure and an above-ground structure.

As shown in FIG. 2, a floor panel 14 is laid on the ground surface G at the stage when the support column 12 is set up. The peripheral edge of the floor panel 14 is attached to the column 12 with a bracket (not shown). As described above, since the installation of the floor panel 14 is a ground operation, the safety of the operation and the shortening of the construction period can be achieved.

As shown in FIG. 3, at the stage where the floor panels 14 are spread, the excavating machine 16 uses the floor panels 14.
Excavate the earth and sand below. As shown in FIG. 6, the excavating machine 16 forms a loading path 20 and a loading path 22 through which the dump truck 18 and the like enter and exit, while forming the floor panel 14.
Is excavated and loaded on the dump truck 18. The dump truck 18 transports and discharges earth and sand to a remaining soil treatment plant through a carry-out path 22. At the same time, the tower crane 24 is installed on the upper surface of the floor panel 14. Thus, the construction of the above-ground structure can be performed without waiting for the completion of the underground structure. It should be noted that, in the predetermined area, the upright of the support is completed, and the floor panel 1
When 4 is laid, the excavation work will be proceeded sequentially from the area, and the construction will be progressed. At this time, a guide rail is provided on the lower surface of the floor panel 14, and an overhead crane 19 for transporting materials of the underground structure is attached. As a result, it is possible to suspend and transport the material of the underground structure transported from the carry-in path 20, so that there is no need to suspend the material from the ground surface after the excavation is completed.

As shown in FIG. 4, the tower crane 2
4, the work of mounting the floor panels 14 on the second floor or more is sequentially performed. At the same time, floor panel 1
Below 4, the excavation and unloading work proceeds.

As shown in FIG. 5, the floor panel 14
When the excavation and unloading work is partially completed below, the underground structures such as the underground pit 26 used for the water storage tank are constructed. On the ground, installation work of an outer wall (not shown) is performed at the same time.

As shown in FIGS. 6 and 7, in the method for simultaneous underground construction of a building according to this embodiment, the underground flow line connected to the underground excavation surface U below the floor panel 14 is used. And a carry-in path 28 as a ground traffic line for transporting materials for constructing the ground structure of the building. Loading path 20 and loading path 2
2 is provided with an inclined surface on which the dump truck 18 and the like can travel from the underground excavation surface U to the ground surface G. Also,
The carry-in path 28 is composed of a panel 32 supported by a pillar 30, and the panel 32 is connected to the carry-in path 20 and the carry-out path 2.
2 and a carry-in path 20 and a carry-out path 22
And the carry-in path 28 are three-dimensionally intersected. This enables smooth transportation of materials and the like.
