<p>The present invention relates to a high-strength synthetic resin pipe which supports the inside of a hollow pipe to properly meet atmospheric pressure and hydraulic pressure, thereby preventing the pipe from being damaged or deformed due to the atmospheric pressure or the hydraulic pressure after being buried underground. The synthetic resin pipe includes: a hollow pipe formed in a helical shape; and a joint member provided between the hollow pipes in a helical shape to join the hollow pipes. The hollow pipe has a tubular body of a rectangular shape with the joint member being attached to both sides of the hollow pipe; a first slope member inclined from one corner of an inner upper portion of the tubular body to the other corner of a lower portion; a second slope member attached to the center of the first slope member on the center, and integrally connected to the other corner of the inner upper portion of the tubular body to one corner of the lower portion; a top surface support portion connected between the upper portions of the first and second slope members, and the inner top surface of the tubular member to support the inner top surface; and a bottom surface support portion connected between the lower portions of the first and second slope members, and the inner bottom surface of the tubular member to support the inner bottom surface.</p> |
