Description
本願発明は、地質改良をするための薬液注入ポンプに関するものである。 TECHNICAL FIELD The present invention relates to a chemical injection pump for soil improvement.
地質改良をするための二連型ポンプ（吸引口と吐出口を二連備えたポンプ）としては、これまでに種々のものが開発されてきた（例えば、特許文献１など）。
Various types of double pumps (pumps having a double suction port and a discharge port) for soil improvement have been developed so far (for example,
しかし、ダブルパッカー工法に使用できる「２台のモーターを別々に運転し１台のクランクケースで２ラインの吐出を制御する機能」と、二液等量や普通注入などに使用できる「２台のモーターを１つのボリュームで吐出変更・運転停止する機能」と、を兼ね備えた薬液注入ポンプは、これまでにあまり開発されていなかった。 However, there is a function that can be used for the double packer method, which can be used to operate two motors separately and control the discharge of two lines with one crankcase, and a function that can be used for two-liquid equal amount and normal injection. Until now, very few chemical injection pumps have been developed that combine the function of changing the discharge and stopping the operation of the motor with a single volume.
そこで、本願発明者は、鋭意試験・研究を進め、両機能を兼ね備えて、それを切替スイッチ１つで変更可能にする薬液注入ポンプを完成するに至った。 Accordingly, the inventors of the present application conducted extensive tests and research, and completed a chemical injection pump that has both functions and can be changed with a single changeover switch.
第１の発明は、地質改良をするための薬液注入ポンプであって、２台のモーターを別々に運転し１台のクランクケースで２ラインの吐出を制御する機能と、２台のモーターを１つのボリュームで吐出変更・運転停止する機能と、を切替スイッチ１つで変更可能にすることを特徴とする薬液注入ポンプである。
第２の発明は、切替スイッチを制御盤に備えていることを特徴とする同薬液注入ポンプである。
第３の発明は、メーター及びスイッチを共有することを特徴とする同薬液注入ポンプである。
The first invention is a chemical injection pump for soil improvement, which has a function to operate two motors separately and control discharge of two lines with one crankcase, and a function to combine two motors into one. This chemical injection pump is characterized in that the function of changing the discharge and stopping the operation with a single volume can be changed with a single changeover switch.
A second aspect of the present invention is the same liquid injection pump, characterized in that a control panel is provided with a selector switch.
A third invention is the chemical injection pump characterized by sharing a meter and a switch.
本願発明によれば、以下のような効果を有する。
（１）１台で２台の役割（等量とＤＰ）を果たすことができる。
（２）切替スイッチのみで切り換え可能なので、極めて簡単に操作できる。
（３）装置をコンパクトにできる。
（４）粘性の異なる液体を等量で吐出することができる。
The present invention has the following effects.
(1) One machine can play two roles (equivalent and DP).
(2) Since it can be switched only by a selector switch, it can be operated very easily.
(3) The device can be made compact.
(4) Liquids with different viscosities can be discharged in equal amounts.
本願発明の実施形態を図面に基づいて説明する。
まず、図１は、本願発明に係る薬液注入ポンプの制御システムを示す説明図である。
図１に図示するように、本願発明に係る薬液注入ポンプ（二連型ポンプ）は、制御盤内に備えた切替スイッチ１０で、二連型ポンプＡ・Ｂを等量（２台のモーターを１つのボリュームで吐出変更・運転停止する機能）とＤＰ（２台のモーターを別々に運転し１台のクランクケースで２ラインの吐出を制御する機能）に切り替えることができるものである。
Embodiments of the present invention will be described based on the drawings.
First, FIG. 1 is an explanatory diagram showing a control system for a liquid injection pump according to the present invention.
As shown in FIG. 1, the chemical injection pump (double pump) according to the present invention uses a
等量モードに切り替えることで、１．５ショット注入（主剤と硬化剤を送液ポンプで個別に注入管に送り注入管の頭部で２液を合わせて、混合された薬液を注入管の先端から吐出して地盤に注入する方式）や２ショット注入（主剤と硬化剤を送液ポンプで個別に注入管に送り、注入管の先端から吐出される瞬間に２液を合わせて混合する方式）が可能になり、二重管ストレーナ工法に使用できる。 By switching to the equal volume mode, 1.5 shots can be injected (main agent and hardening agent are separately sent to the injection tube with a liquid feed pump, the two liquids are combined at the head of the injection tube, and the mixed chemical solution is injected into the tip of the injection tube. method of injecting it into the ground from the top) or two-shot injection (method of sending the main agent and hardening agent separately to the injection pipe with a liquid feed pump, and mixing the two liquids together at the moment they are discharged from the tip of the injection pipe) can be used for the double tube strainer construction method.
ＤＰモードに切り替えることで、１ショット注入（主剤と硬化剤を所定の配合比率で薬液ミキサーによって予め撹拌混合しておき、主剤と硬化剤を混合した１液状態の薬液を圧送して地盤に注入する方式）が可能になり、ダブルパッカー工法に使用できる。 By switching to DP mode, one-shot injection (main agent and hardening agent are stirred and mixed in advance with a chemical mixer at a predetermined mixing ratio, and the one-liquid state chemical mixed with the main agent and hardening agent is pumped and injected into the ground. method) is possible, and it can be used for the double packer method.
また、等量で使用時には、ポンプＢの遠隔ボックス３０内のボリュームで、ポンプＡの遠隔ボックス２０内及びポンプＢの遠隔ボックス３０内のＨｚメーターが連動する。これにより、ポンプＢの遠隔ボックス３０内のボリューム調整でポンプＡ・Ｂの双方を制御できる。
Also, when using the same amount, the volume in the
次に、図２は、本願発明に係る薬液注入ポンプの制御システムを示す回路図である。
図２に図示する回路図により、図１で説明した切替スイッチ１０による等量とＤＰの切り替えを実現することができる。
制御盤と遠隔ボックスをコンパクトに、又、電気トラブルを回避する為に回路をシンプルにすることによって、スイッチ、ボリューム、信号線を極力減らし、視認性、操作性を向上させた。
Next, FIG. 2 is a circuit diagram showing the control system of the liquid injection pump according to the present invention.
By means of the circuit diagram shown in FIG. 2, it is possible to realize switching between the equal amount and DP by the
By making the control panel and remote box compact, and by simplifying the circuit to avoid electrical troubles, the number of switches, volumes, and signal lines has been reduced as much as possible, improving visibility and operability.
本願発明は、地質改良をするための利便性の高い二連型の薬液注入ポンプとして、広く利用できるものである。 INDUSTRIAL APPLICABILITY The invention of the present application can be widely used as a highly convenient double-tube liquid chemical injection pump for geological improvement.
