Figures 1 to 3 show a pumping generation test device as an embodiment of PpJ1 of the present invention. Figure 1 is a plan view thereof, Figure 2 is a cross-sectional view of the PISi diagram, and Figure 3 is a cross-sectional view of the PISi diagram. is a cross-sectional view showing a state in which scum has been formed in the sand.
第１，２図に示すように、回流水槽２の計測部において
、上方の開いた砂箱３が配置されており、同砂箱３内に
微粒子状（本実施例では、５００μｌのふるいにかけた
砂を使用）の砂４が敷き詰められている。As shown in Figs. 1 and 2, a sand box 3 with an open upper part is placed in the measurement section of the circulating water tank 2. The area is covered with sand 4 (using sand).
そして、この砂４は、すべて、１色の塗料で着色されて
いる。All of this sand 4 is colored with one color of paint.
なお、回流水ＷＩ２は、枠１で構成され、その内部には
水が充満されている。＠１．２図においては、回流水槽

略されでいる。Note that the circulating water WI2 is composed of a frame 1, and the inside thereof is filled with water. @1.2 In Figure 2, only the measuring section of the circulating water tank 2 is shown, and all other purchasing sections are omitted.
本発明の第１実施例としての汲置生成試験装置はと述の
ごとく構成されているので、汲置の（Ｌ成拭験を行なう
際１こは、回流水槽２内において水を回流させる。Since the pumping generation test device according to the first embodiment of the present invention is constructed as described above, water is circulated in the circulating water tank 2 when carrying out the pumping (L formation wiping test).
これにより、？ＩＳ３図に示ｒように、矢印ｄの方向に

As shown in the IS3 diagram r, a water flow occurs in the direction of arrow d, and the sand 4 in the sandbox moves little by little from the upstream side to the first stream side and accumulates, forming peaks a, b, and c, that is, the sand The process by which the position is generated is observed.
このとき、砂４は着色されているので、水流による砂４
