Description

The present invention relates to a water immersion waterproofing device in which a groove such as a drainage groove or a rail track installation groove for a vehicle is installed in an opening portion that is orthogonally arranged in a lower floor structure.

In recent years, due to heavy rainfall, floods, etc. in some areas such as urban areas, water has suddenly flown into structures such as buildings, subways, underground malls, underground passages and underground parking lots from openings such as entrances and windows. It was flooded and caused great damage.

In order to prevent a sudden inflow of water from the outside into the opening of such a structure, there is a conventional pile of sandbags that requires a great deal of manpower and time. In addition, as an infiltration waterproofing device installed by the applicant of the present application in the opening portion of the structure, a makuhari cutoff type infiltration waterproofing device (: Patent Document 1) in which a flexible waterproof sheet is laid on the opening portion, a transverse waterproof panel Traverse water immersion waterproofing device (: Patent Documents 2 and 3) that traverses the opening to shut off the opening, and a downward blocking water immersion waterproofing device that is fitted from above to lower the waterproof panel to shut off the opening. (: Patent Document 4), a waterproof sheet is used to quickly block the opening without using a tool, and the number of parts is small, and the structure is simple and can be provided at a low price. Moreover, the side frame of the opening is normally used. Many waterproof sheet-type inundation waterproofing devices (: Patent Document 5) and the like have been developed and introduced in which a waterproof cover can be installed using a rail cover used as.

Among these conventional water immersion waterproofing devices, a traverse blocking water immersion waterproofing device, a descending block type water immersion waterproofing device, etc., are provided with a packing seal mechanism at a lower part and both sides of a waterproof panel, and a packing is provided at a lower body and both side bodies of the opening. It is mounted by tightening with a handle via a sealing mechanism.

However, when an inundation waterproofing device is installed in the opening of a factory, etc., if a drainage ditch or a groove for installing a railroad track for a vehicle is arranged orthogonally or obliquely in the lower floor structure, waterproofing is required. A gap is formed between the lower frame that supports the lower portion of the panel and the groove, and water enters. That is, the water blocking surface is cut at the crossing groove portion in the opening portion, and the water immersion and waterproof function is lost.
