The acid-alkali-resistant collection pipe is based on the traditional drainage pipe, and the acid resistance of the double-wall corrugated pipe is improved through the improvement of the formula; then through the ingenious mechanical design principle, a special set of special, complex structure but convenient to use is designed. The corrugated pipe grooving device with high working efficiency, without affecting the rigidity of the pipe, completes the grooving of the entire (6m/piece) double-wall corrugated pipe trough, thereby preparing a new type of high rigidity and acid resistance Filter tube.
