Device and method for accurately fixing internal waterstop in lakebed tunnel

A device for affixing a waterstop in a lakebed tunnel, comprising:

• a first supporting bar and a second supporting bar arranged in parallel in a first direction, a first transverse clamping bar and a second transverse clamping bar arranged in parallel in a second direction between the first supporting bar and the second support bar, and a first group of and a second group of vertical clamping bars arranged in parallel in a third direction,
• wherein the first group of vertical clamping bars are affixed to the first transverse clamping bar, and the second group of vertical clamping bars are affixed to the second transverse clamping bar, and a space between the first group and the second group of vertical clamping bars is configured to receive the waterstop,
• wherein the first group and second group of vertical clamping bars are configured to directly contact the waterstop such that the length of the waterstop extends in the third direction and the width of the waterstop extends in the second direction,
• wherein the first direction, the second direction, and the third direction are orthogonal relative to one another, and
• wherein each of the first supporting bar, the second supporting bar, the first transverse clamping bar, and the second transverse clamping bar is straight and linear in shape.
