When placing the corrugated pipe, the conical positioning block 3 is inserted into one end of the corrugated pipe, which can quickly position the corrugated pipe. A pair of first corrugated clamps 2 are slidably arranged on the upper surface of the workbench 1. The inner surface of the first corrugated clamps 2 is provided with corrugations adapted to the corrugated pipe. A first reciprocating motion assembly is installed on the upper surface of the workbench 1. After the corrugated pipe is positioned, the first reciprocating motion assembly causes the two first corrugated clamps 2 to move relative to each other, clamping the bottom corrugations of the corrugated pipe.

[0026] A fixed block 14 is fixedly installed on the upper surface of the workbench 1 via a support rod 15. A hydraulic cylinder 11 is fixedly installed on the fixed block 14.

After the movable frame 8 descends to a suitable height, the second reciprocating motion component causes the two second corrugated clamps 12 to move relative to each other. The two second corrugated clamps 12 clamp the top corrugations of the corrugated pipe. Finally, the movable frame 8 moves upward as a whole to perform a tensile test on the corrugated pipe. This test process is relatively quick and convenient. Workers only need to place and pick up the corrugated pipe. Positioning the corrugated pipe is simple and convenient, which helps to improve the efficiency of corrugated pipe testing.

[0027] The first reciprocating motion assembly includes a first threaded rod 4 and a first motor 6. The first motor 6 is fixedly mounted on the upper surface of the worktable 1.
