Description
【０００１】[0001]
本考案は、地下水の排水量を測定する目盛を付けた沈澱槽に関するものであり 、詳しくは沈澱槽の三角堰に排水の流量を測定する目盛を付けた沈澱槽に関する ものである。 The present invention relates to a settling tank equipped with a scale for measuring the discharge of groundwater, and more particularly to a settling tank equipped with a scale for measuring the flow rate of wastewater in a triangular weir of the settling tank.
【０００２】[0002]
種々の地下工事等においては、ある程度の深さになると地下水が排出するが、 この地下水は汚泥等を含む場合が多い。そこで従来から、工事現場においては沈 澱槽を設けておいて、この汚泥等の固形分を含む地下水をいったん沈澱槽に貯溜 して、固形分を沈澱分離せしめた後に地下水の排水をする。 In various underground works, groundwater is discharged at a certain depth, but this groundwater often contains sludge and the like. Therefore, conventionally, a sedimentation tank has been provided at the construction site, and groundwater containing solids such as sludge is temporarily stored in the sedimentation tank, and the groundwater is drained after the solids are separated by sedimentation.
【０００３】 そしてこの地下水の排水を行う際は、その排水量がどの程度であるかを測定す ること、つまり排水流量の管理が必要である。そこで従来は、この排水量の測定 をするには、上記の沈澱槽に三角堰を設け、その三角堰の流出口の最低部から三 角堰における水流の水面までの高さを測定し、その高さの値から公式または早見 表により排水量、つまり流量を求める方法が採られていた。When draining this groundwater, it is necessary to measure how much the drainage is, that is, to manage the drainage flow rate. Therefore, conventionally, in order to measure this amount of wastewater, a triangular weir was provided in the settling tank, and the height from the lowest part of the outlet of the triangular weir to the water surface of the triangular weir was measured, and the height was measured. The method of calculating the discharge amount, that is, the discharge amount, was adopted from the value of the water by formula or a quick reference table.
【０００４】 図２は従来から実施されていた沈澱槽７を示す斜視図であり、２は沈澱槽７の 中間に設けた三角堰であり、５は沈澱槽７の地下水排出口である。そして排水量 を測定するには、三角堰２の流出口６の最低部６ａから流出口を流れる水流の水 面までの高さを測定し、前記の方法でその流量を求めている。FIG. 2 is a perspective view showing a conventional settling tank 7, 2 is a triangular weir provided in the middle of the settling tank 7, and 5 is a groundwater discharge port of the settling tank 7. Then, in order to measure the drainage amount, the height from the lowest portion 6a of the outlet 6 of the triangular weir 2 to the water surface of the water flowing through the outlet is measured, and the flow rate is obtained by the above method.
【０００５】[0005]
上記のように、沈澱槽の三角堰における流出口の最低部から水流の水面までの 高さを測定し、その値から流量を求める方法は、その高さの計測や流量の計算に 時間がかかり、測定回数が多く必要な場合には余分な手間が必要となるのである 。 As described above, in the method of measuring the height from the lowest part of the outlet of the triangular weir of the settling tank to the water surface and determining the flow rate from that value, it takes time to measure the height and calculate the flow rate. However, if a large number of measurements are required, extra labor is required.
【０００６】 本考案は上記の問題に鑑みてなされたものであり、その目的は地下水の排水を 行う際に、その排水の流量を容易にかつ簡便に、つまり短時間に測定することが できる排水量目盛付き沈澱槽を提供することである。The present invention has been made in view of the above problems, and an object thereof is to easily and simply measure the flow rate of groundwater when draining groundwater, that is, the amount of wastewater that can be measured in a short time. The purpose is to provide a graduated settling tank.

本考案者は、上記の課題の解決について種々検討したところ、地下水沈澱槽の 三角堰の両側に、１分間当りのリットル数または１時間当りのｍ3数などの排水 量の流量測定をすることができる目盛を付けることに着目した。The present inventor has made various studies on the solution to the above-mentioned problems, and has been able to measure the flow rate of discharged water such as liters per minute or m 3 per hour on both sides of a triangular weir of a groundwater settling tank. I focused on adding a scale that can be used.
【０００８】 即ち、本考案の要旨は、地下水の排水量の測定に用いる沈澱槽において、該沈 澱槽の三角堰に排水量測定用の目盛を付けたことを特徴とする排水量目盛付き沈 澱槽と、地下水の排水量の測定に用いる沈澱槽において、該沈澱槽の三角堰の両 側にそれぞれリットル／分、ｍ3／時間の排水量測定用の目盛を付けたことを特 徴とする排水量目盛付き沈澱槽である。That is, the gist of the present invention is a settling tank used for measuring the discharge of groundwater, wherein a triangular weir of the settling tank is provided with a scale for measuring the discharge of water. In a settling tank used for measuring the discharge of groundwater, the settling tank equipped with scales for measuring the discharge of liters / minute and m 3 / hour is provided on both sides of the triangular weir of the settling tank. It is a tank.
【０００９】 本考案における、地下水の排水量の測定に用いる目盛付き沈澱槽は、地下水に 含まれる汚泥等の固形分を沈澱分離せしめることと、その沈澱槽に一時的に貯溜 した地下水を排水する際にその流量を測定するために用いるものである。 そしてその沈澱槽の形状、構造などは特に限定されるものではないが、地下水 を一時貯溜して固形分を沈澱して分離するのに必要な、適宣の大きさにする必要 がある。通常用いられている沈澱槽は、三角堰を中仕切りとして設け、一端に地 下水の排出口を設けたものである。In the present invention, the scaled settling tank used for measuring the discharge amount of groundwater is used to separate solids such as sludge contained in groundwater by sedimentation and to drain the groundwater temporarily stored in the settling tank. It is used to measure the flow rate. The shape and structure of the settling tank are not particularly limited, but it is necessary to make the size suitable for the temporary storage of groundwater and the precipitation and separation of solids. A commonly used settling tank has a triangular weir as a partition and a groundwater discharge port at one end.
【００１０】 本考案にかかる沈澱槽は、地下水の排水量の測定に用いるものであるが、排水 の流量を測定する目盛は、上記の沈澱槽の三角堰の両側または片側に設けること が望ましい。そして目盛りは、１分間当りのリットル数や、１時間当りのｍ3数 などを測定することができる目盛とすることが好ましい。 このような目盛を三角堰の両側または片側に付けておけば、沈澱槽から地下水 を排水している際に、三角堰に形成される流出口における水流の水面が上記の目 盛のどの位置にあるかを確かめることによって、その時点における排水量がどの 程度なのかを瞬時に知ることができる。The settling tank according to the present invention is used for measuring the amount of drainage of groundwater, and it is desirable that a scale for measuring the flow rate of drainage is provided on both sides or one side of the triangular weir of the settling tank. It is preferable that the scale is a scale capable of measuring the number of liters per minute and the number of m 3 per hour. If such scales are attached on both sides or one side of the triangular weir, the water surface of the water flow at the outlet formed in the triangular weir will be located at any position on the above scale when draining groundwater from the sedimentation tank. By checking if there is any, it is possible to instantly know how much wastewater is discharged at that time.

以下実施例に基いて本考案を説明する。 図１（１）は、本考案に係る排水量目盛付き沈澱槽の斜視図である。この排水 量目盛付き沈澱槽１は、地下水の固形分を沈澱分離して排水するものであるが、 三角堰２によって３と４の２槽に分割されている。そして三角堰２によって、地 下水排水の流出口６が形成され、さらに三角堰２には、その両側に２ａ、２ｂの ように地下水の排水量を測定するための目盛が付けられている。 また流出口６から排出された地下水は、最終的に排出口５から沈澱槽外に排出 される構造となっている。 The present invention will be described below based on examples. FIG. 1 (1) is a perspective view of a settling tank with a drainage scale according to the present invention. The settling tank 1 with a drainage scale is used to settle and separate the solid content of groundwater for drainage, and is divided into two tanks 3 and 4 by a triangular weir 2. The triangle weir 2 forms an outlet 6 for drainage of groundwater, and the triangle weir 2 is provided with scales 2a and 2b on both sides thereof for measuring the discharge amount of groundwater. Further, the groundwater discharged from the outlet 6 is finally discharged to the outside of the settling tank from the outlet 5.
【００１２】 つぎに図１（２）は、図１（１）に示す排水量目盛付き沈澱槽１の三角堰２の 両側に付けた目盛の一例２ａ、２ｂを示すものである。 そして２ａには地下水排水の流量を、１分当りのリットル数で表示したもので あり、２ｂには同じく排水の流量を、１時間当りのｍ3数として表示した目盛り である。 流出口６における水流の水面が、この目盛のどの位置にあるかを確認すること によって、当該水流の流量を知ることができる。Next, FIG. 1 (2) shows an example 2a, 2b of scales provided on both sides of the triangular weir 2 of the settling tank 1 with a displacement scale shown in FIG. 1 (1). 2a shows the flow rate of groundwater drainage in liters per minute, and 2b shows the scale of drainage flow rate in m 3 per hour. By confirming at which position on the scale the water surface of the water flow at the outlet 6 is located, the flow rate of the water flow can be known.
