Abstract

PROBLEM TO BE SOLVED: To prevent the diffusion of leaked water even when the leakage is generated from a structure by installing a purification area constituted from a material for purifying the leaked water from a storage site under the ground on the downstream side of the installation position of the storage site. SOLUTION: A purification area 2 is installed under the ground on the downstream side of the installation position of a storage site 1. The area 2 is constituted of a material which has good water permeability and can purify leaked water from the site 1. When water in the site 1 leaks into the surroundings caused by the generation of cracks on the bottom surface and side of the site 1, the water is mixed with underground water flowing under the ground. But it is installed on the downstream side of the flow of underground water. A material constituting the purification area 2 has good water permeability and is constituted from a material selected by the kind of the storage material of the site 1. Accordingly, components contained in the underground water are removed directly during the passage of the underground water through the area 2. Therefore, the underground water after passing through the area 2 flows down as purified underground water not containing various components.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure capable of preventing leakage of water from a storage site for storing various materials.

[0002]

2. Description of the Related Art In an outdoor storage site, water accumulates inside because rainwater enters. In order to prevent such water from leaking from the storage site, a plurality of water shields such as water collection pipes are installed around the storage site in addition to the water shield sheet.

[0003]

[Problems to be Solved by the Invention] However, once the bottom or side surface of the storage site is cracked or damaged, the water inside leaks to the surroundings, and such leaks enter the groundwater through the surrounding ground and diffuse. There is also a possibility.

The present invention has been made in order to solve the above-mentioned conventional problems, and provides a structure capable of preventing the diffusion of water even if the water leaks from a structure such as a storage site. The purpose is to:

[0005]

According to the present invention, there is provided a structure for preventing the diffusion of water leakage, wherein the structure for purifying water leakage from a storage site is provided in a basement downstream of a storage site. It is characterized by a structure that prevents diffusion of water leakage, provided with a purification region made of a material to be cleaned.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

<A> Storage site. The storage site 1 for storing various materials, materials, and the like is generally constructed on the ground and in the ground with an open upper space. Therefore, long-term rainwater has accumulated. Storage 1
Underground where is installed, groundwater flows,
As described above, it is an object of the present invention to prevent the leakage of water from the storage site 1 by such groundwater.

<B> Installation of a purification area. A purification area 2 is installed in the basement downstream of the installation location of the storage facility 1. The purification area 2 is made of a material having good water permeability and capable of purifying water leakage from the storage site 1. In this case, it is particularly effective to use a material selected according to the type of the storage material in the storage space 1. This purification area 2
For example, it can be constructed by various known underground wall construction techniques or ground improvement techniques. Since the purification area 2 has a certain width, depth, and thickness, water is passed through this area together with groundwater to be purified.

<C> Purifying material. As a material for purifying water leakage from the storage site 1, for example, the following materials can be used alone or in combination to form an area. Physical adsorbent such as activated carbon. Biologically decomposed substances such as microorganisms. Synthetic substances such as chelating materials. Metals such as iron.

<D> Installation of a water stop wall. Further, it is effective to connect and construct the water blocking wall 3 around the purification area 2. Various construction methods are known for a technique of constructing a wall surface with a water-stopping material in the ground. This underground water barrier 3
In particular, if it is constructed with a shape that is expanded toward the upstream of groundwater,
Groundwater can be guided to the purification area 2 from a wide range.

<E> Action. If the water inside leaks to the surroundings due to cracks on the bottom and side surfaces of the storage site 1, it mixes with the groundwater flowing underground.
In the drawing, the range of diffusion is indicated by a. However, in the structure of the present invention, the purification area 2 is provided downstream of the flow of the groundwater. The material constituting the purification region 2 has good water permeability and is made of a material selected according to the type of storage material in the storage site 1. Therefore, components contained in the groundwater are directly removed while the groundwater passes through the purification area 2. Therefore, the groundwater after passing through the purification area 2 flows down as purified groundwater containing no various components.

[0012]

The structure for preventing the diffusion of water leakage according to the present invention is as described above. Therefore, once water leaks from the structure, the components contained in the water leakage can be purified in the purification region 2. . Further, the maintenance cost and the management cost can be significantly reduced as compared with a method of pumping and collecting groundwater which may have entered the leaked water.
