The latest tool that plays the role of sandbags in the event of flood damage! Flood Prevention Sheets” High Flood Prevention Effectiveness and Durability

In recent years, flood damage caused by heavy rains and typhoons exceeding expectations has occurred in many parts of Japan every year, causing extensive flooding damage that is difficult to recover from in residences and facilities. It is highly likely that such flood damage will continue to occur in the future. It is necessary to be prepared to prevent damage before it happens, and not to think of it as someone else’s problem.

The best way to prevent flooding and other water damage is to physically contain the water. Sandbags are a common material that serves as a watertight barrier.

Unlike bulldozers, sandbags can be installed only in an emergency and are still used at various sites because they are expected to provide a certain level of flood prevention. However, although the sandbag mechanism itself is very simple, it has a weak point as a material for disasters. They are difficult to keep on hand and are not sufficient for emergency preparedness.

This article introduces the Delta Panel, an excellent flood prevention tool that can replace sandbags. We will explain the features of this “delta panel,” focusing on its effectiveness and durability, so please read on if you are considering flood prevention measures.

Problems with common flood control material "sandbags

First, let us reiterate the widely known flood control material, “sandbags. Sandbags are materials used in the role of sturdy floodwalls or weights by filling cloth bags with soil, sand, or other materials to create a mass of volume and weight. Multiple sandbags are stacked on top of each other to eliminate gaps. They are used in a variety of situations, such as flood control and civil engineering sites. Because they are very simple and sturdy, sandbags are widely used, but when you actually use them, you will find that they are difficult to handle.

• Large quantities of sediment are needed and difficult to keep on hand.
• Time consuming to prepare and install, not suitable for emergency response
• Requires skill and experience to achieve sufficient watertightness
• Bags are not durable and not suitable for repeated use

Large quantities of sediment are needed and difficult to keep on hand.

The use of sandbags requires large quantities of sediment to be packed in bags. In agricultural areas, it may be possible to arrange sandbags on a daily basis, but in general, it is not easy to keep sandbags on hand. Especially in urban areas, it may be difficult to arrange sand and soil. Therefore, sandbags are insufficient as a countermeasure against flood damage that can occur in any region.

Time consuming to prepare and install, not suitable for emergency response

Sandbags are used by filling each bag with sand and sand and piling them up, which requires a considerable amount of time from preparation to installation. However, in situations where flooding is imminent or damage has already begun, the response is time-sensitive. In general, it is estimated that it takes two adults approximately 100 minutes to build a sandbag wall 4m wide high enough to prevent flooding. This is not enough time to respond to an instantaneous heavy rain disaster.

Requires skill and experience to achieve sufficient watertightness

Due to their nature, sandbags are stacked to form a “wall. Because each sandbag is a bag, it is easy for gaps to occur, and it takes skill and experience to achieve a sufficient watertight effect. In a situation where an unimaginable amount of water flows in at a moment’s notice, even a small leakage can lead to serious damage. Therefore, sandbags with inadequate water sealing effect are considered suboptimal.

Bags are not durable and not suitable for repeated use

Sandbags are made from polyethylene or other synthetic fibers. In general, most sandbags are disposable, and once used in the event of flooding, they must be disposed of. This is a problem from a cost perspective, especially in areas where frequent flooding is a concern.

Delta Panel, a state-of-the-art flood prevention tool that replaces sandbags to serve as a watertight barrier

In light of the recent flooding situation, responding with sandbags will require a great deal of effort. It is necessary to consider materials and tools that have both a mechanism for emergency response and a high water stopping effect, as well as durability that is as strong as sandbags. As a tool for flood countermeasures in this day and age, we would like to introduce the “Delta Panel” manufactured by Taiyo Kogyo Corporation. Delta Panel is a flood prevention sheet with a patent-pending mechanism.

 

Flexible, lightweight, and durable membrane materials are combined with aluminum frames, pipes, and mesh sheets to create a triangular cross-section that is stable and strong enough to resist the force of rising water. The following points are some of the features that make it capable of handling major water damage.

• High waterproofing and water sealing effect and strong durability
• Lightweight and compact for easy storage
• Installation ready for emergencies
• Economical because it can be reused repeatedly
• Can be used at any installation location

High waterproofing and water sealing effect and strong durability

使用しているシート素材は合成樹脂製で、その高い防水性と大きな力にも耐えられる強度が特徴です。この樹脂膜は引き裂き強度もきわめて高く、70kg～80kgほどの力にも耐えられます。一般的なテントなどに用いられる膜素材の5倍以上の強度です。

さらにシート以外でも、アルミフレームやパイプ、メッシュシートなど、いずれも耐久性を備えた素材を使用しており、特許出願中の三角断面構造によって増水による水圧にも対抗できる強度を生み出しています。

また、加工面においては、生地同士を溶かして接続面を一体化させる溶着技術によって一切の隙間を失くすことで水漏れ防止も徹底されています。他にも、各パネルを連結して使用するため連結部分には二重の止水ファスナーが施されています。

Lightweight and compact for easy storage

Each delta panel has a compact structure with a height of 60 cm and a width of 110 cm. On top of that, it is extremely lightweight, weighing only 2.5 kg. Since it is in sheet form, it can be rolled up and folded when not in use, saving space for storage and stockpiling.

Installation ready for emergencies

Delta panels can be installed in as little as 10 minutes. The simple structure of a single panel is completed by simply raising the sheet and inserting the pipes, so anyone can install it quickly. No tools are required, so all you need is a Delta Panel to get it up and running quickly.

Economical because it can be reused repeatedly

Delta panels are designed for repeated reuse. Once they are dried and disassembled, they can simply be stored away and have no durability issues. Therefore, they can be installed immediately for re-use.

 

Can be used at any installation location

DELTA PANELS are designed to be connected horizontally with multiple panels to accommodate a variety of building frontage widths. The sheet-like structure also makes it possible to adhere to surfaces, even on uneven ground, making it possible to choose any installation location.

 

summary

In the future, torrential rains and typhoons may become even more powerful. In order to prepare for such possible situations, it is necessary to prepare more responsive and effective flood control methods.

DELTA PANEL is the latest flood prevention sheet, which has solved the problems of sandbags and existing materials. Its high effectiveness and convenience make it one of the best solutions in the current flood prevention measures. If you are considering countermeasures, please contact us for more information.
