As shown in figures 1-6, the fixture for positioning the longitudinal drain pipe of the tunnel comprises a frame body 1 and a barrel body 2 which are integrally formed. Two sides of the bottom end of the frame body 1 are provided with L-shaped bases 17, and the bases 17 are provided with fixing holes 18; a pair of clamps 11 is symmetrically arranged at the top of the frame body 1, and each clamp 11 is connected with the cylinder body 2; the outer wall of the cylinder body 2 is connected with a nut cover 12, and a pull rod 3 is arranged in the nut cover 12; a clamping arm support 4 is fixed at the top end of the pull rod 3, and connecting lugs 5 are fixed at two ends of the clamping arm support 4; the connecting lug 5 is rotatably connected with a supporting rod 6; the bottom end of each clamp 11 is respectively provided with a main rod 7 and an auxiliary rod 10 which are connected with the frame body 1; one end of the main rod 7 is connected with the branch rod 6, and the middle part of the main rod 7 is rotatably connected with a first shaft rod 8; the secondary rod 10 is rotatably connected with a second shaft rod 9.

Wherein: the bottom center of the frame body 1 is provided with a cylinder body 2.

The outer wall of the cylinder body 2 is connected with the nut cover 12 through screw threads.

The nut cover 12 is connected with the pull rod 3 in a rotating way. The pull rod 3 is driven to move up and down by rotating the nut cover 12.

The interior of the cylinder 2 is connected with a pull rod 3 in a sliding way.

The two ends of the first shaft lever 8 and the two ends of the second shaft lever 9 are fixedly connected with the two ends of the inner wall of the frame body 1, so that the main lever 7 and the auxiliary lever 10 at the two ends rotate by taking the first shaft lever 8 and the second shaft lever 9 as axes respectively when being opened and clamped, and displacement is prevented from being generated in rotation.

Each clamp 11 comprises a fixed seat 13 and a clamping plate 16; one end of the fixed seat 13 is provided with a clamping groove 14, the other end is provided with a groove, and the inner wall of the groove is respectively connected with the main rod 7 and the auxiliary rod 10; two corners of one end of the clamping plate 16 are round corners, and the other end is provided with a clamping block 15, and the clamping block 15 is embedded into the clamping groove 14.
