On the other hand, the square pipe is adopted to be circumferentially coiled into the closely-arranged multiple rows without adopting the circular pipe, because the top wall of the square pipe is larger than the top wall of the circular pipe in area, the area of the outer surface of the middle layer of the circular pipe-shaped compression resistance formed by the multiple rows of the closely-arranged square pipe circumferentially coiled is larger, and the stress area is increased, so that the compression resistance is improved. The square pipe is adopted, and the side walls of the square pipe are planes, so that the side walls of all the rows can be mutually attached, the top walls of all the rows can be connected together without gaps, namely the top walls are arranged more tightly, more pipes can be wound in unit area, and the circular pipe-shaped compression-resistant middle layer can bear larger side soil layer extrusion force as a whole. By adopting the connecting structure, the two sewage pipes are not fixed by only relying on the friction force between the pipe hoop and the pipe wall, and the fixing is realized by relying on the supporting force of the annular bulge to the annular groove, so that the pipe hoop can fix the two sewage pipes more reliably.
