PURPOSE: A connection structure for a waveform steel pipe with a dual structure is provided to be conveniently constructed and to strengthen the water-tightness. CONSTITUTION: A connection structure for a waveform steel pipe with a dual structure comprises a connecting band(40), silicone(60), and an annular band(50). The connecting band connects both sides of the waveform steel pipe(30) using a fastening bolt(50). The silicone is filled to seal the contact between a waveform steel pipe(20) and a plastic flat pipe(10). The annular band connects the external surface of the waveform steel pipe to the lower part and the upper part using a fastening bolt(51). |
