Abstract
The invention discloses a device and a method for accurately fixing an internal waterstop in a lakebed tunnel, comprising two supporting bars arranged in parallel, two transverse clamping bars arranged in parallel between the supporting bars, vertical clamping bars arranged on the transverse clamping bars, wherein the supporting bars, the transverse clamping bars and the vertical clamping bars are mutually perpendicular, at least two vertical clamping bars are arranged on each transverse clamping bar, and the vertical clamping bars are arranged at the inner side of the transverse clamping bars. The beneficial effects of the invention are as follows: With vertical clamping bars that clamp the waterstop, the invention can limit the movement and rotational degree of freedom of the waterstop within in the space, to avoid displacement of the waterstop, thus making the construction more productive.
