Description

  The present invention relates to a water stoppage device that is installed in a passage and prevents water in a flooded area from flowing into a protected area.

  Conventionally, various water stop devices have been proposed in order to minimize inundation damage to underground facilities and buildings.

  Water stoppages installed in the traffic area of people and things, such as the ground part that serves as entrances to underground facilities, underground passages, and entrances to buildings, have already been flooded. Prevent damage by placing it at the boundary (hereinafter referred to as the water-stop boundary) between the area (hereinafter referred to as the flooded area) and the area (hereinafter referred to as the protection area) where the flood damage is to be suppressed. What to do is widely adopted.

  As an example of the water stop tool proposed so far, for example, one in which a flexible sheet is arranged (hereinafter referred to as a sheet type) can be cited (for example, see Patent Document 1).

  The sheet-type water stop device extends and locks a flexible sheet stored in advance under the floor surface of the water stop boundary to prevent water leakage from the left and right edges. This is to prevent flood damage. According to this sheet-type water stop device, it is possible to shorten the time required for setting the water stop state in an emergency.

  However, in the case of a sheet-type water stop device, the sheet is generally stored under the floor. Therefore, it is necessary to perform groove-shaped excavation work on the floor surface of the water stop boundary, and depending on the installation location, whether or not the work is possible becomes a problem.

  In addition, lids are usually provided in the grooves that store the sheets so as not to obstruct traffic, but dust and mud enter through the slight gaps in the lids, so that the sheet deteriorates over time or quickly In some cases, the installation work may be hindered, and even if the floor surface can be processed, the use of a sheet-type water stop device has been discouraged.

  Moreover, it is necessary to install the sheet-type water stop device in a stretched state, and water cannot be stopped in a slack state.

  For this reason, in the case of a seat-type water stoppage device installed at a place where the expected flooded water level is high, it is difficult for an evacuee in the flooded area to evacuate across the seat to the protected area, Even if the water level was low, the evacuation route had to be blocked in some cases.

  This invention is made in view of such a situation, Comprising: Without providing construction over the whole floor surface of a water stop boundary part, the water stop tool which can change the height of a water stop surface is provided. To do.

  In order to solve the above-mentioned conventional problems, in the water stop device according to the present invention, (1) in the water stop device which is installed in the passage and prevents the water in the flooded region from flowing into the protection region, A pair of left and right rails standing adjacent to the side walls, a water stop panel disposed in a watertight manner between the left and right rails, and a continuous connection over substantially the entire upper edge of the water stop panel, And a flexible waterproof sheet configured to be substantially flush with the water-stop surface of the water panel and can be expanded in a water-tight manner with respect to the left and right rails.

In addition, the water stop device according to the present invention has the following features.
(2) The water stop sheet is wound from the upper end and can be stored in the upper part of the water stop panel.
(3) A sheet crimping rail for crimping both end edges of the waterproof sheet to the left and right rails when the waterproof sheet is extended.
(4) An anchor member for standing the sheet crimping rail is disposed on the upper end surface of the water stop panel.
(5) A supporting member that supports the water pressure from the flooded area from the protection area side of the waterproof sheet when the waterproof sheet is extended.
(6) The water stop panel is configured to be locked in a watertight manner with respect to the left and right rails via a crimping mechanism.

  According to the water stop device according to the present invention, in the water stop device which is installed in the passage and prevents the water in the inundation region from flowing into the protection region, a pair of standing upright adjacent to the left and right side walls of the passage. Left and right rails, a water stop panel disposed in a watertight manner between the left and right rails, and a continuous connection over substantially the entire area of the upper edge of the water stop panel, and above the water stop surface of the water stop panel. And a flexible water-stop sheet configured to be watertight and expandable to the left and right rails, so that the water-stop surface can be applied without performing construction over the entire floor surface of the water-stop boundary. It is possible to provide a water stop device that can change the height of the water.

  In addition, the water stop sheet is wound from the upper end so that it can be stored in the upper part of the water stop panel. The space to be kept can be used more efficiently, transportation and installation work of the water stop to the water stop boundary can be facilitated, and the work of extending the water stop sheet can also be performed quickly.

  In addition, if the waterproof sheet is provided with a sheet crimping rail that crimps both edges of the waterproof sheet to the left and right rails when the waterproof sheet is extended, water leakage through both edges of the waterproof sheet can be more reliably prevented. can do.

  In addition, if an anchor member for erecting the sheet crimping rail is disposed on the upper end surface of the water stop panel, there is no need to excavate an anchor portion for erecting the sheet crimping rail on the floor surface, Further, since the anchor portion is closer to the operator's hand compared to the case where the anchor portion is formed on the floor surface, the engagement operation of the seat crimping rail to the anchor portion can be performed accurately and quickly. .

  In addition, since the supporting member that supports the water pressure from the flooded area from the protection area side of the water stop sheet is provided when the water stop sheet is extended, the water stop sheet to which the water pressure has acted can be securely held.

  Moreover, since the said water stop panel was comprised so that it might lock to the said right and left rail through a crimping | compression-bonding mechanism in a watertight state, the adhesiveness of a water stop panel and a left and right rail is improved, and the watertight state which can endure the water pressure of a deep part Can be made more solid.

  Hereinafter, an embodiment of a water stop device according to the present invention will be described with reference to the drawings.

  The water stop device according to the present embodiment is a member for constructing a water stop facility at a desired place where it is desired to prevent inundation from the flooded area side. In this embodiment, as shown in FIG. A water stoppage facility A is constructed in the middle of the underground passage U that connects the underground ticket gate.

  Specifically, a water stop panel 20 in which a water stop sheet 30 is connected to the upper part is disposed on a pair of left and right rails 40L and 40R that are erected on the floor F adjacent to the wall surfaces W on both sides of the underground passage U. Thus, a water stop facility A is constructed to prevent inflow of water from the flooded area X side to the protected area Y side.

  The water blocking panel 20 includes a panel body 21 having a rectangular plate shape made of metal. In addition, a water-stop sheet 30 made of a flexible material made of a flexible resin is connected to the upper edge of the panel body 21 so as to extend.

  The water stop panel 20 is normally stored in a separate storage warehouse (not shown), and as shown in FIG. 2, only the left and right rails 40L and 40R for receiving the water stop panel 20 are installed in the underground passage U. The traffic of people and goods is possible.

  As shown in FIG. 3A, the water stop sheet 30 is connected to the upper edge of the panel body 21 and converges to form a small volume when not flooded, and is provided at the upper edge of the panel body 21. The binding band 22 is wound in a wound state, and the binding band 22 is unwound when in use, and is unfolded in a sheet form from the upper edge of the water stop panel 20 as shown in FIGS. 3 (b) and 3 (c). As shown in FIG. 1, it is laid between the left and right rails 40L, 40R to be in a stretched state.

  Moreover, as shown in FIG.3 (b), the sheet | seat press-fit rail 70 (refer FIG. 1) is provided in the site | part corresponding to the left-right edge part of the upper end surface of the water stop panel 20, ie, the water immersion side of the left-right rails 40L and 40R. A square-shaped anchor member 24 into which the lower end is fitted is provided.

  Therefore, when the waterproof sheet 30 is stretched between the left and right rails 40L, 40R, first, as shown in FIG. 4, the waterproof panel 20 that converges the waterproof sheet 30 is installed between the left and right rails 40L, 40R. The lock handle 23 is pressed and fixed. In the following description, the state shown in FIG. 4 (the state where the water stop panel 20 is arranged on the left and right rails 40L and 40R but the water stop sheet 30 is not extended) is referred to as “low water level protection state”. ".

  Next, as shown in FIG. 1, the waterproof sheet 30 is extended and stretched between the left and right rails 40L, 40R, and both side edges of the waterproof sheet 30 are placed on the waterproof surfaces of the left and right rails 40L, 40R. The sheet is clamped via the sheet pressing rail 70.

  At this time, the sheet crimping rail 70 is fitted and erected in the anchor member 24 at the upper end of the water stop panel 20, and the fulcrum-over engagement fitting 72 provided on the upper end surface is provided on the upper end surfaces of the left and right rails 40L and 40R. The left and right rails 40L, 40R and the water stop sheet 30 are assembled in an integrated manner with the water stop panel 20 provided in the upper part in a pressure-bonded state via the engagement fitting receiving piece 44.

  Further, on the protection area Y side of the water stop sheet 30, the intermediate rail 50 erected in the intermediate rail erection hole 80 formed on the floor surface F, and the intermediate rail 50 and the left and right rails 40L and 40R are installed. A plurality of reinforcing bars 60 form a substantially lattice-shaped support portion 90.

  This support part 90 is for supporting the water pressure from the flooded area | region X provided to the water-stop sheet 30 extended. Hereinafter, the state as shown in FIG. 1 (the state in which the water stop panel 20 and the water stop sheet 30 are extended between the left and right rails 40L and 40R and the support portion 90 and the sheet crimping rail 70 are disposed) is referred to as “high”. It is called “water level protection state”.

  And according to a water stop provided with such a structure, it is not necessary to perform construction over the whole floor surface of a water stop boundary part like the conventional sheet type water stop, and in order to stand up the intermediate rail 50 Since the intermediate rail standing hole 80 is formed, the installation location is not limited, and the water stop facility A can be constructed in more various locations.

  Moreover, the water stop equipment A constructed by the water stop device according to the present embodiment has a high water stop surface such as the low water level protection state shown in FIG. 4 and the high water level protection state shown in FIG. It is possible to change the length.

  Therefore, when the water level of the inundation area X is low, the low water level protection state prevents the intrusion of the evacuee P while preventing the inundation to the protection area Y side while preventing the traffic of the evacuees P. Can be tolerated.

  Further, when the water level in the flooded area X rises, flooding into the protected area Y can be prevented if the high water level protection state is set.

  Further, as a further feature point of the water stop device according to the present embodiment, it is possible to cope with a high water level, but the load required for transporting the water stop panel 20 when constructing the water stop facility A is low. It is done.

  For example, as disclosed in Japanese Patent Application Laid-Open No. 2001-98792, it has been proposed in the past that a panel is disposed at a water-stop boundary portion to prevent water intrusion. Another panel was installed on top of the panel, and the panels were stacked high to prevent water from entering the protected area.

  However, it is necessary to store the number of panels corresponding to the assumed water level in the vicinity of the water stop place, and it is difficult to secure the storage space for the number of sheets to be stored depending on the place. In addition, when a storage space is secured at a slightly distant place, since it is separated from the water stop boundary portion, another problem arises that extra time is required to transport the panel in an emergency.

  On the other hand, in the water stop device according to the present embodiment, the water stop sheet 30 for constructing the water stop surface when the water level is flooded is usually converged on the upper part of the water stop panel 20 and has a small volume. Therefore, the storage space in normal times can be small. Moreover, it is not necessary to carry the panel of the number according to the assumed water level, and there exists an effect that the burden at the time of constructing the water stop equipment A is very small.

  Next, each constituent member of the water stop device according to this embodiment described above will be described in more detail.
