Description

本考案は、近年、液状化現象の被害が相次いで生じている状況であり、新築を考える際には、地震の強固に関心を示す人が増えている。そこで、この液状化現象を一般人又は施工者が住宅を建築する際に、基礎工法の違いにより生ずる現象を擬似的に再現するための液状化現象再現装置に関するものである。  In recent years, the present invention is a situation in which damage from liquefaction has occurred one after another, and when considering new construction, an increasing number of people are strongly interested in earthquakes. Therefore, the present invention relates to a liquefaction phenomenon reproducing apparatus for reproducing in a pseudo manner a phenomenon caused by a difference in a basic construction method when a general person or a builder constructs a house.

従来、この種の模型家屋の現物を使用して、液状化現象と基礎工事に対する施工効果を明確に説明すると云う再現装置の模型は散見されていない現状である。  Conventionally, there has been no reappearance of a model of a reproduction device that clearly uses the actual model of this type of model house to clearly explain the liquefaction phenomenon and the construction effect on the foundation work.

従来の技術で知られているものでは、容器に砂と水を注入し、容器を左右に動作して液状化現象を起こしたものか、または、ペットボトルに砂と水を注入し、これを振って液状化を起こしているのが現状である。
然し、上記の様な方法を以って説明しても、現実に液状化現象によって生ずる家屋の移動、傾斜状態は、施工業者、施主にとっては、不明確であると云う問題点がある。
本考案のものは、上述の問題点を解決するためのものであり、その目的とする所は、簡易性を有し、携帯に便利な液状化現象再現装置によって、基礎工法の相違を容易に詳しく説明できる液状化より生ずる問題点を簡単に解決するためのものである。
In the known technology, sand and water are poured into a container and the container is moved left and right to cause a liquefaction phenomenon, or sand and water are poured into a plastic bottle. At present, it is liquefied by shaking.
However, even if the method described above is used, there is a problem that the moving and inclined state of the house actually caused by the liquefaction phenomenon is unclear for the contractor and the owner.
The object of the present invention is to solve the above-mentioned problems, and the object of the invention is to simplify the difference in the basic construction method with a liquefaction phenomenon reproduction device that is simple and portable. This is to easily solve the problems caused by liquefaction that can be explained in detail.

上記目的を達成するために、本考案の液状化現象再現装置によれば、略四角形の透明なアクリル容器に対して、内部に各種の細砂と水を注入する。該アクリル容器には、内部の細砂の上面に簡易性を有する模型家屋を載置する。該アクリル容器の下部に載置した防振容器には、内部に振動モーターと乾電池を列設収納してある。また、該防振容器の下部には、防音用ウレタンを収納した振動抑制板を敷設したものである。  In order to achieve the above object, according to the liquefaction phenomenon reproducing apparatus of the present invention, various fine sand and water are injected into a substantially rectangular transparent acrylic container. In the acrylic container, a model house having simplicity is placed on the upper surface of the fine sand inside. The vibration-proof container placed under the acrylic container contains a vibration motor and a dry battery inside. In addition, a vibration suppression plate containing soundproof urethane is laid under the vibration isolation container.

本考案は、以上の如く構成されているので、一般人又は施工業者又は施主等が実際に生ずる液状化現象の重大な恐ろしい現実を体験できる便利な効果と、アクリル容器内に細砂と水との上部に模型家屋を地表面に載置すると云う簡単な方法で液状化現象が容易に生ずると云う便利な効果がある。また、該アクリル容器の下端に設置した防振容器によっては、背面等に設けたスィッチにより、振動モーターが駆動して液状化現象が確実に起きる効果と、更に、電池容器の下部に敷設した防音用ウレタン使用の振動抑制板によって、各所で使用する場合でも騒音と振動を確実に防止すると云う便利な効果もある。  Since the present invention is configured as described above, the ordinary person, the contractor or the owner can experience the terrible reality of the liquefaction phenomenon that actually occurs, and the fine sand and water in the acrylic container. There is a convenient effect that a liquefaction phenomenon easily occurs by a simple method of placing a model house on the ground surface in the upper part. In addition, depending on the vibration-proof container installed at the lower end of the acrylic container, the vibration motor is driven by a switch provided on the back surface or the like, and the liquefaction phenomenon is surely caused. The use of a vibration suppression plate made of urethane for urethane also has a convenient effect of reliably preventing noise and vibration even when used in various places.

上記のように構成されている液状化現象再現装置によれば、アクリル容器内に細砂と水を注入し、付属の混合棒で撹拌する。その後、実験したい付属の模型家屋を地表面に埋設する。そして、防振容器のスィッチにより振動モーターを駆動し、液状化現象が発生した状態を観察で出来るようになっている。
次に、実験が終了後は、模型家屋を取り除く作業をした後に、再度混合棒でよく撹拌し、再度実験が出来るようにする。
また、実験が終了後には、該アクリル容器に付属品である蓋体をして水分の蒸発を防止して、次回の使用時に便利とするものである。
更に、液状化現象が起こりにくい場合は、水分が蒸発している可能性があるため、少しずつ水分を補給して実験を可能とする。なお、観察のポイントとしては、液状化現象が起こると、地表面に水分が流出すると同時に地盤沈下が発生し、模型家屋の種類と、基礎工事の種類により模型家屋の傾斜具合等を充分に観察して確認するものである。
According to the liquefaction phenomenon reproduction apparatus configured as described above, fine sand and water are poured into an acrylic container and stirred with an attached mixing rod. Then, embed the model house you want to experiment on the ground. The vibration motor is driven by the switch of the vibration isolating container so that the state where the liquefaction phenomenon occurs can be observed.
Next, after the experiment is completed, after removing the model house, it is thoroughly stirred again with a mixing rod so that the experiment can be performed again.
In addition, after the experiment is completed, a lid as an accessory is attached to the acrylic container to prevent evaporation of moisture, which is convenient for the next use.
Furthermore, when the liquefaction phenomenon is unlikely to occur, the moisture may have evaporated, so the experiment can be performed by gradually replenishing the moisture. As a point of observation, if liquefaction occurs, water will flow out to the ground surface and at the same time land subsidence will occur, and the inclination of the model house will be sufficiently observed depending on the type of model house and the type of foundation work. To confirm.

該アクリル容器(1)の内部の該細砂(2)には、表面に模型家屋(5)を載置するものである。
次に、該アクリル容器(1)には、下部に防振容器(6)を設置する。該防振容器(6)には、図3及び図4に示す如く、内部に振動モーター(7)を所定位置に取着すると共に、内周面にウレタン等よりなる防音材(8)(8)を内貼してある。また、該防振容器(6)の内底部には、図4に示す如く電池容器(9)に複数の乾電池(10)を収納直付けしてある。
また、該電池容器(9)には、底部に防音用ウレタン(12)より形成された振動を吸収する振動抑制板(11)を敷設した構造となっている。
