【０００１】
【発明の属する技術分野】
本考案は、土壌、岩礫、建設残土、最終処分場への搬入廃棄物の物性を調べるために三軸圧縮試験機内に準備された供試体に任意の湿度を持つ気体・ガス・空気を浸透・透気させることを可能にするものである。
【０００２】
【従来の技術】
従来の土質試験用三軸圧縮試験機では、背圧と称して三軸圧縮試験機内に準備した供試体内部に水圧を加える手法が既に存在している。
【０００３】
【発明が解決しようとする課題】
前記圧力供給装置から気体・ガス・空気が三軸圧縮試験機内に流入する間に気体・ガス・空気の湿度を任意の大きさに制御し、安定した流量を維持しながら三軸圧縮試験機内に供給すること。
【０００４】
【課題を解決するための手段】
前記圧力供給装置から供給される気体・ガス・空気を一次密閉式容器内の液体内部に供給することで液体内にエアーバブルを発生させる。エアーバブルが前記一次密閉式容器内の空間内ではじけこわれることで空間内の湿度が変わる。前記圧力供給装置に取り付けられている圧力制御弁を調整することでエアーバブルの発生量がコントロールできる。
【０００５】
【実施例】
図１のように前記圧力供給装置に前記圧力制御弁を取り付ける。さらに前記一次密閉式容器に液体をいれ、二次密閉式容器内に前記湿度計を入れる。
【０００６】
前記圧力供給装置、前記圧力制御弁、前記一次密閉式容器、二次密閉式容器、三軸圧縮試験機を一次管路および二次管路でつなぐ。
【０００７】
前記一次管路末端は必ず、液体に内に沈める。前記二次管路始端は前記一次密閉式容器内の液体に絶対に触れさせない。
【０００８】
圧力供給装置を稼動し、気体・ガス・空気を一次密閉式容器内の液体中に送り込み、液体内でエアーバブルを発生させる。
【０００９】
エアーバブルが液面上でこわれ水滴および蒸気が空間に拡散し空間内の温度が変化する。
【００１０】
気体・ガス・空気の湿度は前記二次密閉容器内に置かれた湿度計によって測定される。
【００１１】
湿度の増減は前記圧力制御弁によって気体・ガス・空気の流量を増減することで制御する。
【００１２】
任意の湿度をもつ気体・ガス・空気は前記二次密閉容器を経て、三次管路をとおり三軸圧縮試験機へ流入し、供試体内へ浸透・透気した後、四次管路を経てて三軸圧縮試験機外へ排気される。
【００１３】
【発明の効果】
土壌、岩レキ、建設残土、最終処分場への搬入廃棄物にたいする任意の湿度環境下における物性測定に大いに貢献する。また、廃棄物については汚染物質を含んだ浄化方法の研究開発に役立つものである。

TECHNICAL FIELD OF THE INVENTION
The present invention permeates gas, gas and air with arbitrary humidity into specimens prepared in a triaxial compression tester to investigate the properties of soil, debris, construction surplus soil, and waste brought into the final disposal site. -It is possible to make it air permeable.
[0002]
[Prior art]
In the conventional triaxial compression tester for soil test, there is already a method of applying water pressure to the inside of a specimen prepared in the triaxial compression tester, called back pressure.
[0003]
[Problems to be solved by the invention]
While the gas / gas / air flows into the triaxial compression tester from the pressure supply device, the humidity of the gas / gas / air is controlled to an arbitrary size, and while maintaining a stable flow rate, into the triaxial compression tester. To supply.
[0004]
[Means for Solving the Problems]
By supplying gas, gas, and air supplied from the pressure supply device to the inside of the liquid in the primary sealed container, an air bubble is generated in the liquid. The humidity in the space changes as air bubbles are blown off in the space in the primary sealed container. The amount of air bubbles generated can be controlled by adjusting the pressure control valve attached to the pressure supply device.
[0005]
【Example】
As shown in FIG. 1, the pressure control valve is attached to the pressure supply device. Further, the liquid is poured into the primary sealed container, and the hygrometer is placed in the secondary sealed container.
[0006]
The pressure supply device, the pressure control valve, the primary hermetic container, the secondary hermetic container, and the triaxial compression tester are connected by a primary line and a secondary line.
[0007]
The primary line end is always submerged in the liquid. The beginning of the secondary conduit never touches the liquid in the primary closed container.
[0008]
By operating the pressure supply device, gas, gas and air are sent into the liquid in the primary sealed container to generate air bubbles in the liquid.
[0009]
Air bubbles are broken on the liquid surface, and water droplets and vapor diffuse into the space, and the temperature in the space changes.
[0010]
The humidity of gas, gas, and air is measured by a hygrometer placed in the secondary sealed container.
[0011]
The increase or decrease of the humidity is controlled by increasing or decreasing the flow rate of gas, gas or air by the pressure control valve.
[0012]
Gas / gas / air having an arbitrary humidity passes through the secondary airtight container, flows into the triaxial compression tester through the tertiary conduit, permeates and permeates into the specimen, and then passes through the quaternary conduit. Exhausted outside the triaxial compression tester.
[0013]
【The invention's effect】
It greatly contributes to the measurement of physical properties of soil, rock rubble, construction waste, and waste brought into final disposal sites under any humidity environment. In addition, waste is useful for research and development of purification methods that include pollutants.
