PDS ZERO-SLOPE PROTECTION SIPHONIC DRAINAGE AND COLLECTION METHOD AND CONSTRUCTION PROCESS

摘要

A pds zero-slope protection siphonic drainage and collection method, comprising: water soaking into soil continuously flows into a siphonic drainage grrove (5) through macromolecular protection drainage specially-shaped plates (3); the water in the siphonic drainage groove (5) gathers at a water outlet; by using a diameter-variable pipe at the water outlet, full flow is formed in a straight siphonic pipe, so as to form syphonage; then the water flows into an observation well (8) and a collection well (9); finally, the water is reused. Also provided is a construction process for pds zero-slope protection siphonic drainage, comprising sequentially laying adhesive strips, a siphonic drainage groove (5), macromolecular protection drainage specially-shaped plates (3), a diameter-variable pipe, an observation well (8), and a collection well (9). The drainage system does not require a slope, and the collected water can be reused.
