Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents rainwater from flowing in from an entrance of a subway, an underground mall, an underground passage, a basement, an underground parking lot, a general house, etc. in the event of a flood, an abnormal water discharge such as a high tide or a water pipe burst As described above, the present invention relates to an inundation preventive weir for stopping water.

[0002]

2. Description of the Related Art Conventionally, in order to prevent inundation of underground facilities such as subways, underground malls, underground passages, basements, underground parking lots and general houses during floods, high tides, and abnormal water discharges such as water pipe ruptures. , A water stop weir is installed to stop temporary water at the entrance of underground facilities and underground passages. As the water stop weir, for example, as shown in FIG. 15, a dug portion 50 is provided on a floor surface or a passage surface, and a lid body 51 that stands up when water comes out and forms a weir plate is provided in the dug portion 50. At the same time, there is known a device (conventional example 1) in which a hydraulic jack 52 for raising the lid 51 is provided in the dug portion 50.

[0003]

However, in the case of the above-mentioned conventional example 1, since the hydraulic jack 52 is used as the drive means for erecting the lid body 51, in addition to the hydraulic jack 52, this hydraulic jack 52 is used. It is necessary to provide a large digging portion having a space for installing a drive source for driving 52, and although the operation is easy, there is a problem that the device becomes large and installation cost increases. .

There is also a problem that if the dug portion 50 is flooded due to water leakage, the hydraulic jack 52, the drive source, or the like will break down and control will be lost. Furthermore, since water cannot be stopped at the area where it is connected to the wall surface, it has been necessary to close the gap between the wall surface and the dam plate or install sandbags to prevent water leakage.

On the other hand, in view of the problem of the conventional example 1, in Japanese Patent Laid-Open No. 2001-227255, as shown in FIG. 16, a storage groove 60 is formed in the transverse direction of the floor surface, and the storage groove 60 is formed in the storage groove 60. The tide sheet 61 is stored in the tide sheet, the tide sheet 61 is pulled out from the storage groove 60 at the time of flood, and the side portions of the tide sheet 61 are watertightly fixed to the side rails 62, 62 installed on the wall portions, respectively. The tide sheet device (conventional example 2) has been proposed.

[0006] In the case of this device, since a small digging portion can be formed on the floor surface to form a storage groove, the construction can be carried out on a small scale, and since there is no drive source, the installation cost is low. Although there is an advantage to be completed, the tide sheet 61
When the side portions of the tide sheet are fixed to the side rails 62 fixed to the wall surface, as shown in FIG. 17, the side portions of the tide sheet 61 are sandwiched between the mold material 63 and the side rails 62, and in this state. Since bolts 64 penetrating the tide sheet and the mold material are fastened with tightening nuts to secure the tide sheet 61 and ensure watertightness, the tide sheet 61
If the fastening with the tightening nut is loose, the bolts 64 penetrating the sea tide sheet 61 serve as substantial support points, and therefore the sea tide sheet 6
1 has a problem that tearing easily occurs. This problem tends to occur especially when a weak woman or the like stretches the tide sheet.

Therefore, the main problem of the present invention is that the construction scale for installation is small and the construction is small, and since the drive source is not included, the installation cost is low, and from the housed state, for example, simply above. (EN) It is intended to provide a flood control weir that can be installed by a very simple operation such as pulling it up and hanging it.

[0008]

In order to solve the above-mentioned problems, the present invention according to claim 1 provides a digging portion on the bottom surface side of the water infiltration inlet portion, and at least both sides of the water infiltration inlet portion. A columnar container for a water blocking weir sheet that is continuous to the digging portion is provided, and a substantially U-shaped frame that is normally housed between the digging portion and the columnar housing for the water blocking weir sheet is provided on the upper side. Supported swingably around the fulcrum,
Further, a water blocking weir sheet whose entire circumference is fixed along the substantially U-shaped frame, the dug portion, and the columnar container for the water blocking weir sheet is provided, and the substantially U-shaped frame is swung when water is prevented from entering. There is provided a water infiltration prevention weir characterized in that the substantially U-shaped frame frame is supported by the holding means in a state where the water stop weir sheet is expanded.

According to a second aspect of the present invention, the holding means of the substantially U-shaped frame is a suspending line suspended from an upper position of the water inlet portion, or a stand installed on the floor. An inundation prevention weir according to item 1 is provided.

According to a third aspect of the present invention, a column for a water blocking weir sheet is provided in which a dug portion is provided on the bottom surface side of the water entry port, and at least both sides of the water entry port are continuous with the dug portion. A storage body is provided, and a water blocking weir sheet whose bottom side and both sides are fixed along the columnar storage body for the dug portion and the water blocking weir sheet is provided, and both sides of the water blocking weir sheet are lengthwise from the upper side. A watertight prevention, characterized in that a fastener portion extending at least to the dug portion along the direction is provided, and a water blocking weir sheet portion sandwiched between the two fastener portions can be accommodated in the dug portion in a normal state. Weirs are provided.

According to a fourth aspect of the present invention, the digging portion is supported so as to be tiltable along the longitudinal direction of the digging portion with the lower end being the center of rotation, and is normally tilted and accommodated in the digging portion. At the same time, one or a plurality of columns for supporting the intermediate portion of the water blocking weir sheet that are erected to prevent water infiltration and support the midpoint of the upper side of the water blocking weir sheet are arranged.
A flood control dam as described is provided.

In the above-mentioned present invention, since the water stop weir is made of a sheet and is housed in the dug portion formed on the floor and the columnar container for the water stop weir sheet, the structural scale for installation is large. The construction work will be small and small, and the installation cost will be low because there is no drive source. Further, since the side portions of the water blocking weir sheet are arranged in advance in a manner of being fixed to the columnar container portion for the water blocking weir sheet, the water tightness between the water blocking weir and the wall surface portion and the water blocking weir are secured. It becomes possible to install it from the housed state by a very simple operation, for example, simply pulling it up and hanging it, without the need to fix the side part of the.
