2rotate up, be about to regulate the delivery port 6-2 aperture of water inlet pipe group 6 to open.
In addition, the influence of dynamic water formed by the differential water pressures inside and outside pile body, delivery port 6-2 can open in aperture further.Wherein, the trace moved between the second cross bar 8-4 and the first cross bar 8-3 reflects by following equation:
(sinα-0.05+0.05cosγ)
2+(2-cosα-0.05sinγ)
2＝1
sinβ＝sinα-0.05+0.05cosγ
