Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem such that linkage and versatility to other soil tests are poor in conventional technologies because soil samples and test specimens to be experimented must be placed in the same space where the temperature is controlled. <P>SOLUTION: In a circulated type humidity controller, a humidity-controlled space by salt and a region in which the humidity-controlled air comes into contact with soil samples and test specimens are separated and those two areas are connected with a pipeline. The humidity-controlled air in the pipeline is circulated with a metering pump to promote humidity control to the soil samples and test specimens. In the circulated type humidity controller, the humidity-controlled space and the space to control the humidity of the soil samples can be separated, therefore applicability of a combined system for different experiments/measurements of soil samples can be enhanced. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

本考案は、土壌、岩レキ、建設残土などの材料の保水性、透気性を調べることを可能にするものである。 The present invention makes it possible to examine the water retention and air permeability of materials such as soil, rock reclaim, and construction residual soil.

従来の塩を用いた蒸気圧法は密閉されたガラスデシケータ内に過飽和溶液と土試料を保存するものである。 The conventional vapor pressure method using salt is to store a supersaturated solution and a soil sample in a sealed glass desiccator.

Problems to be solved by the invention

従来の技術では、温度制御空間内に実験対象の土試料や供試体を同一空間内に保存しておかなければならず、他の土質試験への連動性や汎用性に欠ける。 In the conventional technology, the soil sample and specimen to be tested must be stored in the same space in the temperature control space, and lack of linkage and versatility to other soil tests.

Means for solving the problem

過飽和塩溶液あるいは固体状の塩と蒸留水を前記制御タンクに入れ、化学的作用で湿度制御を受けた空気を、前記可動タンクを発生源とする空気の流れによって前記制御タンクから空気を移動させ、管路でシステム全体をつなぎ、閉塞させることで湿度制御空気を恒常的に循環させる。 A supersaturated salt solution or solid salt and distilled water are put into the control tank, and the air subjected to humidity control by chemical action is moved from the control tank by the flow of air using the movable tank as a source. By connecting the entire system with a pipe line and closing it, humidity control air is circulated constantly.

図１のように制御タンク内にガラス容器に納めた塩と蒸留水を入れ一次管路と二次管路を制御タンクにつなぐ。 As shown in FIG. 1, salt and distilled water contained in a glass container are placed in a control tank, and the primary and secondary pipes are connected to the control tank.

測定タンク内に湿度センサーを納め、二次管路と三次管路を測定タンクにつなぐ。 Place the humidity sensor in the measuring tank and connect the secondary and tertiary pipes to the measuring tank.

前記三次管路をアクリル製モールドにつなぐ。 The tertiary conduit is connected to an acrylic mold.

前記アクリル製モールド内には、土試料を充填しておき、土試料の両端面は有孔板に接触させておく。 The acrylic mold is filled with a soil sample, and both end surfaces of the soil sample are brought into contact with a perforated plate.

前記アクリル製モールドの前記三次管路をつないだ面とは異なる他方の面に四次管路をつなぐ。四次管路の他端は、定量ポンプを納めた可動タンクにつなぐ。 A quaternary pipe is connected to the other surface of the acrylic mold that is different from the surface connecting the tertiary pipe. The other end of the quaternary pipe is connected to a movable tank containing a metering pump.

前記可動タンク内に納めた前記定量ポンプを、前記一次管路につなぐ。 The metering pump stored in the movable tank is connected to the primary pipeline.

実施例 Example

までの操作を終了した段階で循環型湿度制御装置が組み上がり、循環型湿度制御装置内の空気が閉塞空間内で連続することになる。At the stage where the above operations are completed, the circulation type humidity control device is assembled, and the air in the circulation type humidity control device continues in the closed space.

前記可動タンク内の定量ポンプを可動させることで、循環型湿度制御装置内で空気の流れおよび循環が生まれ、前記制御タンク内の塩によって湿度制御された空気が前記測定タンクを経て土試料内を透気し再度、前記可動タンクおよび前記制御タンクに戻り、湿度制御を恒常的に受け、再び土試料内を透気する。 By moving the metering pump in the movable tank, air flows and circulates in the circulation type humidity control device, and the air whose humidity is controlled by the salt in the control tank passes through the measurement tank and the soil sample. Air permeates again, returns to the movable tank and the control tank, receives humidity control constantly, and again permeates the soil sample.

前記定量ポンプを長時間可動させることで、土試料内の間隙は制御湿度と等しくなる。 By moving the metering pump for a long time, the gap in the soil sample becomes equal to the control humidity.

The invention's effect

考案した循環型湿度制御装置によって、湿度制御空間と土試料への湿度コントロール空間が分離できるため土試料への異なる実験・測定を併用したシステムへの応用性が高められる。 The devised circulating humidity controller can separate the humidity control space and the humidity control space for the soil sample, so that the applicability to a system that uses different experiments and measurements on the soil sample is enhanced.
