The upper ends of the two groups of positioning angle plates 5 are rotationally connected through a connecting channel steel 6. A group of positioning blocks 8 are correspondingly installed on the side plates close to the two groups of positioning angle plates 5. A positioning slit for placing the embedded waterstop 9 is provided between the two groups of positioning blocks 8. The middle parts of the two groups of positioning angle plates 5 are fixedly connected through a connecting member;

[0017] When the utility model is installed, the support assembly is placed on one side of the low side wall of the tunnel, and according to the installation height of the embedded waterstop 9, the installation height of the support beam 2 is correspondingly fixed through multiple sets of fixing parts. After the fixing of the support beam 2 is completed, the embedded waterstop 9 is abutted against the positioning assembly, and then the rotatable and movably installed positioning angle plate 5 is rotated, and the two groups of positioning angle plates 5 are locked through the connecting parts.
