Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a basement water leakage prevention panel used in underground structures such as basements.

[Conventional technology]

Generally, walls such as basements and underground garages are formed by pouring concrete. In such underground concrete structures, in order to prevent penetration or infiltration of underground water, the outer surface of the concrete structure is covered with a waterproof material such as asphalt, which is an expensive process. Alternatively, waterproofing may be achieved by lining the inner surface of a concrete structure with waterproof paint.

[Problem that the invention attempts to solve]

However, concrete cannot prevent water from penetrating as it is, and as mentioned above, even if the outer surface of concrete is covered with a waterproof material, cracks often occur after it is poured, so it is difficult to completely avoid water leakage. Repair work is also difficult. In this case, it is possible to achieve complete waterproofing by using plenty of high-quality waterproofing materials and performing thorough construction, but such construction will lead to a significant increase in construction costs.

On the other hand, if the inner surface of the concrete is lined with waterproof paint, the pressure of groundwater seeping in from the outside of the concrete acts in a direction that causes the lining to peel off, making it easy for water to leak from weak points in the lining. is a very tricky person.

It is also possible to create a highly water-proof underground space by lining the inner surface of a concrete structure with panels made from water-impermeable materials such as synthetic resin or metal plates; If the water that accumulates between the surface and the panel is not drained, the water pressure will create a large buoyancy on the structure, and in extreme cases, the structure may even float.

[Means for solving problems]

The basement water leakage prevention panel of the present invention is, for example,
The panel body is made of a water-impermeable material such as FRP (fiber reinforced synthetic resin) or metal plate, and serves as the inner wall surface of the underground concrete structure, and the tubular water guide installed vertically or laterally along the panel body. It includes a passage, and a water passage hole or a water passage groove that is provided in the water introduction passage and opens on the outer surface side of the panel main body to communicate the inside and outside of the water introduction passage.

[Effect]

The basement water leak prevention panel having the above structure is formed into a container shape by integral molding of FRP or by connecting a plurality of panel segments. Then, after being installed as an inner concrete pouring panel for an underground structure such as a basement, concrete is poured.

Since there are a sufficient number of water holes or water grooves on the outer surface of the panel, that is, between it and the concrete, underground water that has penetrated through the concrete and leaked to the panel side can be absorbed through the water holes or the water grooves. It is taken in from the water ditch and enters the water guide passage. The leaked water that has flowed into the water guide passage is collected in a water storage section or the like provided at an appropriate position in the underground structure, and is drained as necessary.

[Example 1] Underground structure 1 shown in Figures 1 to 4
This is a container-shaped basement water leakage prevention panel 2 with an open top side and a concrete wall 3 placed on the outside side, and is used, for example, in a basement. The panel 2 is formed into a container shape by connecting a plurality of (for example, six) panel segments 2a to 2f. A suitable sealing material 4 (see FIG. 3) is applied to the connecting portions of the segments 2a to 2f to prevent water leakage.

The panel 2 includes a panel body 5 made of a water-impermeable material such as FRP or a metal plate, and this panel body 5 constitutes the inner wall surface of the underground concrete structure. The panel body 5 is preferably made of synthetic resin material such as FRP in order to prevent condensation.
Metal plates can also be used if used in conjunction with heat insulating materials.

The panel main body 5 has a plurality of water guide passages 6a in the vertical direction along its side wall 5a (see FIG. 2).
A plurality of water guide passages 6b, 6c are provided in the horizontal direction (substantially horizontal direction) along the bottom wall portion 5b.
(See Figure 1) is attached. These water guide passages 6a, 6b, 6c each have a tubular shape, and the third
As shown in part in the figure, it is preferable that it be formed substantially integrally with the panel main body 5. However, water guide passages 6a, 6 formed separately from the panel main body 5
b, 6c may be attached to the panel body 5 by suitable means.

The vertical water guide passage 6a communicates with the horizontal water guide passage 6b at its lower end. The water guide passage 6b preferably communicates with a horizontal water guide passage 6c arranged at the lowest position. A drain port 8 of this water guide passage 6c is open to a water storage section 9. This water storage section 9 is provided with a drainage device 10 such as a sump pump.

A large number of water holes 12 are provided in the water guide passages 6a, 6b, and 6c along the length thereof. These water holes 12 are all connected to the panel main body 5.
It opens on the outer surface side, that is, on the concrete wall 3 side. These water holes 12 are water guide passages 6a, 6b,
The inside and outside of 6c are communicated.

To bury the panel 2 having the above configuration, first, a hole of a required size is dug in the ground, concrete is poured into the bottom of the hole, and the panel 2 is placed in the hole before it hardens. An outer frame material is assembled in advance on the inner surface of the hole, and a gap of an appropriate size is created between this frame material and the outer surface of the panel 2. Concrete is then poured into the gap and allowed to harden. In other words, the panel 2 also functions as a formwork for concrete, and is buried as is.

Note that a ceiling material (not shown) or the like is provided on the upper opening side of the panel 2. Further, the inner surface of the panel 2 can be used as is, but it is covered with appropriate interior materials such as flooring and wall materials to make it a living area.

In the underground structure 1 with the above configuration, when underground water or the like penetrates through the concrete wall 3 and reaches the panel 2, this leaked water flows through the nearest water hole 12 to the water guide passage 6a (or 6b, 6c). The water is taken in and discharged from the drain port 8 to the water storage section 9.

Therefore, excessive water pressure does not act on the panel 2. Therefore, it is possible to prevent the panel 2 from receiving upward force due to water pressure and from causing water leakage from weak points of the panel 2. Note that since the amount of water that penetrates through the concrete wall 3 and reaches the panel 2 is not so large, the drainage device 10 may be driven as necessary.

[Embodiment 2] The embodiment shown in FIG. 5 is an example in which a cylindrical water guide passage 6 made separately from the panel body 5 is attached to the outer surface side of the panel body 5. In this case, if the panel body 5 is made of metal, the water guide passage 6 can be fixed to the panel body 5 by welding. In addition, reinforcing ribs 14 are provided on the inner surface of the panel body 5 in the vertical and lateral directions.
has been reinforced. Other structures may be the same as in the first embodiment described above. Note that a water passage groove may be provided instead of the water passage hole 12.

[Embodiment 3] In the embodiment shown in FIGS. 6 to 9, the panel main body 5 is integrally molded from FRP or the like, and reinforcing ribs 14 are attached to the inner surface of the panel main body 5.
Further, water guide passages 6a, 6b, and 6c are provided on the outer surface side. A plurality of water passage holes 12 or water passage grooves are formed in each of the water introduction passages 6a, 6b, and 6c as in the previous embodiment. An interior material 16 (see FIG. 8) such as a floorboard is provided on the indoor side of the reinforcing rib 14.

The underground structure 1 of this embodiment has an opening on the left side in the figure, and vehicles and the like can be taken in and out from the ground through this opening 1a. Therefore, this underground structure 1 is suitable for an underground garage or warehouse.
Since the structure and operation other than that are the same as those in the first embodiment, the same reference numerals are given to the parts common to those in the first embodiment, and a description thereof will be omitted.

[Example 4] The example shown in FIGS. 10 and 11 is as follows:
Tubular water guide passages 6a, 6 are provided on the inner surface of the panel body 5.
b, 6c are provided. Further, on the outer surface side of the panel main body 5, a water passage hole 12 is provided which communicates with these water introduction passages 6a, 6b, and 6c.

According to such a configuration, the water guide passages 6a, 6
Since b and 6c also function as reinforcing ribs, the structure is simple despite its high strength. Interior material 1 is provided on the indoor side of these water introduction passages 6a, 6b, and 6c.
6 is provided. Note that the water passage hole 12 may have a groove shape.

[Effect of idea]

By using the panel for underground structures of the present invention, it is possible to construct an underground structure with extremely high water impermeability, low humidity and good livability, and it is possible to prevent excessive water pressure from being applied to the panel. Moreover, since the panels of this invention remain underground as linings for underground structures, they can be used as inner formwork when pouring concrete.
