[0004]

In the above prior art, when an underground building is constructed in a location where groundwater is leached intensely, there is a risk that the underground building will float due to the buoyancy of the groundwater.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. In constructing an underground structure, it is possible to discharge the groundwater smoothly, and even after constructing the underground structure, the groundwater can be removed. It is an object of the present invention to provide an underground building floor panel that can smoothly discharge water and prevent the underground building from floating due to the buoyancy of groundwater.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a drainage tank provided with a groundwater introduction pipe at the bottom is fitted to a floor panel body, and a lower part of the drainage tank is attached to the floor panel. It is characterized by being projected from the lower surface of the main body and fitted to a kiln place of base concrete for laying floor panels, and further provided with a main pipe for introducing groundwater at the bottom of the floor panel main body. .

[0007]

FIG. 1 shows an embodiment of the present invention, in which a metal drain tank 2 provided with a groundwater inlet pipe 1 protruding from the bottom thereof is provided.
A steel plate 4 is fitted to a panel frame 3 made of a mold steel by welding and stretched and fitted to a steel floor panel main body 5 and welded and integrated via an angle 6, and the lower part of the drainage tank 2 is placed on the floor. It is made to protrude outward (downward) from the lower surface of the panel main body 5 so as to be fitted to the pot place 8 (recess for water collection) of the base concrete 7 for laying the floor panel. The present invention relates to a floor panel 10 for an underground structure, wherein a main pipe 9 for introducing groundwater is protruded and provided.

In FIG. 1, reference numeral 11 denotes a cover plate to be attached to the opening on the upper surface of the drainage tank 2, and reference numeral 12 denotes a floor finishing material which is stretched on the indoor side surface of the floor panel body 5 via a joist material 13. is there.

FIG. 2 shows an embodiment in which an underground building is constructed by using the underground building floor panel 10 of the present invention. The base concrete 7 is cast on the bottom of a hole formed in the ground 14. A desired number of the underground building floor panels 10 are laid, and the lower part of the drainage tank 2 of the underground building floor panel 10 is fitted to the kiln 8 of the base concrete 7, and further, on the underground building floor panel 10, Wall panels 15,
15, ... and roof panels 16,16, ...
If necessary, backfill concrete 17 is cast on the outer peripheral surface of the wall panels 15, 15,..., And coated concrete 18 is cast on the outer surface of the roof panels 16, 16,. To build.

Further, the floor panel 1 for an underground structure according to the present invention described above.
When constructing an underground structure using the underground water, when draining groundwater, for example, in FIG. 1 and FIG.
Groundwater that leaches when the base concrete 7 is cast before laying the floor panel 10 for underground construction is collected in the kamaba 8 and a drainage pump (not shown) is put in the kamaba 8 to enter the kamaba 8. The collected groundwater is drained, and then the groundwater leached in laying the underground building floor panel 10 on the base concrete 7 as shown in FIGS. 10 drainage tanks 2
The groundwater introduction pipe 1 is opened, and a hermetic plug 19 is fitted to the groundwater introduction main pipe 9 and sealed as shown in FIG. As shown in FIG. 5, a drainage pump 20 is installed in the drainage tank 2 to discharge the groundwater collected in the drainage tank 2, and the groundwater leached after the construction of the underground building is the groundwater of the underground building floor panel 10 in FIG. The sealing plug 19 of the introduction main pipe 9 is removed to open the groundwater introduction main pipe 9 as shown in FIG. 4, and a plug 21, a joint pipe 22 and a hose 23 are sequentially connected to the opening, and then the hose 23 is As shown in FIG. 5, by connecting to the connecting pipe 24 of the drain tank 2 and sealing the ground water introducing pipe 1 of the drain tank 2, the ground water introducing main pipe 9, the plug 21, the joint pipe 22, the hose 23 and the connecting pipe are connected. Via tube 24 Groundwater collected in by connexion sump 2 with aggregating sump 2 to the drainage pump 20 installed in the exhaust water tub 2 as shown in FIG. 5 may be discharged.

In FIG. 1, reference numeral 25 denotes the joint pipe 2;
5 is a through hole for exposing the underground structure 2 to the surface of the floor panel 10 for underground structures. In FIG. 5, 26 is a drainage pipe for draining groundwater collected in the drainage tank 2 to the outside (ground), 27
Is a rope for suspending and installing the drainage pump 20 inside the drainage tank 2; 28, a float for setting the drainage level of the drainage tank 2; 29, a weight for holding the float 28 in a predetermined position; It is a rope that suspends and supports the float 28 and the weight 29 inside the drainage tank 2.

[0012]

As described above, according to the present invention, a drain tank provided with a groundwater introduction pipe at the bottom is fitted to the floor panel body, and the lower part of the drain tank is projected from the lower surface of the floor panel body. Then, the floor panel is laid on the base concrete basin for laying the floor panel, and the main pipe for groundwater introduction is provided at the bottom of the floor panel body. Groundwater leached during construction can be collected and drained into a drainage tank via a groundwater introduction pipe, and groundwater leached after construction of an underground structure must be collected and discharged into a drainage tank via a groundwater introduction main pipe. And the underground structure can be prevented from rising due to the buoyancy of the groundwater.
