Description

  The present invention relates to a water tank that prevents disasters such as flooding of houses due to heavy rain and typhoons.

  In recent years, with the global warming, the temperature of seawater has risen, cumulonimbus clouds have developed in a short time, and it has become a torrential rain with hourly precipitation far exceeding 50 mm. The number of torrential rains has increased 1.3 times in 30 years and is still increasing in recent years. Precipitation far exceeds the civil engineering design standards of the Ministry of Land, Infrastructure, Transport and Tourism. As a result, rivers overflow in a short period of time, and water overflows from sewage and drainage channels, causing inundation damage to houses. Radar observations by the Japan Meteorological Agency have progressed, and predicted precipitation amounts for each region are issued with warnings 15-20 minutes ago. Torrential rains frequently occur from noon to evening, especially in summer. However, there are few young men during this time, and women and the elderly will deal with it. A quick response is required, but in the past, such disasters have generally been dealt with by using soil or water.

  However, sandbags are as heavy as 20 kg and require a lot of work to handle, making it difficult to secure emergency situations. In addition, the water tank is a technology to prevent water intrusion by putting water in a trash bag or plastic tank, etc., but it takes time to procure and is difficult to use. is necessary. It cannot cope with the change in the situation where the flow speed increases due to the increase in water, and stable countermeasures cannot be taken. There are many difficulties in dealing with emergencies, which is a cause of flood damage to houses. The problem is that it is possible to prevent flooding safely and easily in a short time.

  Patent Document 1 discloses a structure in which a planter is remodeled, and soil is usually put in the planter to cultivate flower trees and contribute to the landscape, and in the event of a disaster, the planters are connected together to be waterproofed. In Patent Document 2, a linear resin is laid on the inner side of a container in which a non-water-permeable cloth having a resin coating on its surface is sewed into a cylindrical shape and a bottom surface is sewn with a similar cloth. Are used to plant flowers and plants as a planter in normal times. It has been disclosed that it is used by pressing, and its surface is freely deformed to stop water by increasing the pressure density.

  When a torrential rain warning is issued, an inundation prevention water tank is connected and installed at the inundation risk point. An elbow-shaped flood prevention water tank is placed at the upstream end, and fixed to an existing fixed object to prevent outflow. The elbow reduces pressure from the water flow and prevents cavitation, creating a smooth flow and guiding it downstream. To stabilize the water tank for preventing flooding at the tip, an iron weight is inserted to increase its own weight. Add a weight according to the situation. When installation is complete, fill all inundation prevention water tanks. In this way, it is possible to prevent inundation by creating a water wall with a water tank for preventing inundation. If the flow rate increases, put a weight in each water tank according to the situation to stabilize. When there is a risk that the volume of water will increase, install vertically stacked water tanks, stack and fill with water, and put a weight according to the situation to stabilize. Buoyancy is generated at about two-thirds of the height of the paddle box, so a weight is put in to stabilize it, and the binding hole is used to strengthen the binding to the existing fixed object to stabilize the installation.

As a countermeasure against an existing place where the ground contact surface is bad, water leakage can be prevented by using a cushioning material between the bottom of the inundation prevention water tank. Further, a buffer material may be pasted on the bottom surface of the water tank before use. The material of the buffer material may be sponge, urethane, etc., and may be rubber.

As the material of the water tank for preventing flooding, hard plastic is suitable, but any material can be used as long as it is a material that can prevent flooding and is lightweight.
