The utility model relates to a super dark shield in aquatic constructs well structure that starts / hang out, the well that starts / hang out sets up in the aquatic, and upper portion is weak stratumpart, and the lower part is stereoplasm rock stratum part, the well bore of weak stratum part includes the enclosure wall, the interior interior lining wall that is of enclosure wall, and top -down isprovided with the horizontal ring frame roof beam of multichannel in the interior lining wall, the well bore of stereoplasm rock stratum part includes ejector anchor protective system, the interior interior lining wall that is of ejector anchor protective system, the shield constructs the well bore bottom that the portal is located stereoplasm rock stratum part. The utility model discloses structural stability is good, and the security is high, and the leak protection waterborne is strong, and the well bore structure combines the setting of the actual geology circumstances for the implementation progress, construction space is good with the hoist and mount spaces, and resoluble breach dikes territory complex environment and the river that forbids the cutout gush / the construction difficult problem of the well that starts / hang out in the river course.
