At the same time, we installed a low-capacity pump in the lower stage, so the high-capacity pump in the higher stage can pump up most of the water and scum in the pump manhole, and further pump up the wastewater containing scum at the lower stage. This can prevent scum from accumulating at the bottom of the pump manhole.

ある。<Example> An example of the present invention will be explained in detail with reference to the drawings. In Fig. 1, numeral 3 is a pump manhole according to the present invention, and the top surface is formed in the shape of a step at the bottom of the pump manhole. An invert plate 4 is installed. A high-capacity pump 5 with a large capacity is installed on the high stage 4a of the invert plate 4, and a low-capacity pump 6 with a small capacity is installed on the lower stage 4b of the invert plate 4. In the figure, 7 and 8 are discharge pipes for drainage connected to pumps 5 and 6, respectively.
上記実施例に於いては２個のポンプ５，６を使
用した場合について説明したが、このポンプは更
に増加することが可能である。 In the above embodiment, a case has been described in which two pumps 5 and 6 are used, but the number of pumps can be further increased.
更に図中上方のLWL（No.１）は高容量ポンプ５
による排水ラインであり、下方のLWL（No.２）は
低容量ポンプ６による排水ラインである。 Furthermore, the upper LWL (No. 1) in the figure is the high capacity pump 5.
The lower LWL (No. 2) is a drainage line by the low capacity pump 6.
又、従来の前述の第２図に示すポンプ２及び本
考案で使用されるポンプ５，６の夫々の口径と、
第１図に示す水の深さH1，H2及び第２図に示す
水の深さH3との関係は次の数式によつて表示さ
れる。 In addition, the respective diameters of the conventional pump 2 shown in FIG. 2 and the pumps 5 and 6 used in the present invention,
The relationship between the water depths H 1 and H 2 shown in FIG. 1 and the water depth H 3 shown in FIG. 2 is expressed by the following formula.
H1，H2，H3＝（2.1〜2.5）×ポンプ口径
第１図に示すポンプユニツトの能力（ポンプ
５，６の能力の和）と第２図に示すポンプユニツ
トの能力（ポンプ２，２の能力の和）を同一とす
ると、ポンプの容量はポンプ５＞ポンプ６，ポン
プ５＞ポンプ２，ポンプ２＞ポンプ６となる。 H 1 , H 2 , H 3 = (2.1 to 2.5) × pump diameter If the sum of the capacities of pumps 2 and 2 is the same, then the capacities of the pumps will be pump 5>pump 6, pump 5>pump 2, and pump 2>pump 6.
従つてポンプ６の口径が一番小さくなる。その
結果第１図に於いては水の深さH1＞水の深さH2
となり、第１図に示す本考案のポンプ６と第２図
に示す従来のポンプ２とを比較すると前者の方が
低水位迄ポンプアツプすることが出来、これによ
つてスカムを含む残水を少なくすることが出来
る。 Therefore, the diameter of the pump 6 is the smallest. As a result, in Figure 1, water depth H 1 > water depth H 2
Therefore, when comparing the pump 6 of the present invention shown in Fig. 1 with the conventional pump 2 shown in Fig. 2, the former can pump up to a lower water level, thereby reducing residual water containing scum. You can.
更に本考案に於いては第１図に示す如く、ポン
プマンホール３の底部を階段状インバートプレー
ト４で構成しているので、その効果を更に助長す
ることが出来る。 Furthermore, in the present invention, as shown in FIG. 1, the bottom of the pump manhole 3 is constituted by a stepped invert plate 4, so that the effect can be further enhanced.

位迄吐出管８を介して排出することが出来る。 When operating the pump manhole according to the present invention, only the high capacity pump 5 is operated up to LWL (No. 1), and most of the water and scum in the pump manhole 3 is discharged through the discharge pipe 7. , the water level is this
When the water level drops below LWL (No. 1), the low capacity pump 6 is operated to pump the wastewater including the scum accumulated at the lower stage of the invert plate 4 to the discharge pipe 8 until the water level reaches LWL (No. 2). It can be discharged through.
