A kind of anti-flattening infiltration type water pipe, including waterproof cloth, water-pipe body and decompression piece. Fluid-tight two side of waterproof cloth connects and encloses structure accommodating space and form water seepage hole. Water-pipe body sets what accommodating space, and inner sidewall encloses structure water channel and the prominent fin of its wall surface. Fin extends along the overall length of water-pipe body length direction. Water-pipe body forms apopore. Decompression piece sets what accommodating space, and decompression piece inner sidewall and water-pipe body lateral wall enclose structure pressure reduction space, and decompression piece forms the through-hole between connection what accommodating space and pressure reduction space, and apopore is connected between what pressure reduction space and water channel. This creation will not be crushed when preventing water-pipe body from being squeezed by soil, it is ensured that water channel and pressure reduction space provide the water source flowing space, and prevent apopore and through-hole from being blocked by soil, and lower the hydraulic pressure at water source.一種防壓扁滲透式水管，包括防水布、水管本體及減壓片。不透水的防水布二側相接而圍構容置空間且形成滲水孔。水管本體設於容置空間，其內側壁圍構水道且其壁面突出凸肋。凸肋沿水管本體長度方向之全長延伸。水管本體形成出水孔。減壓片設於容置空間，減壓片內側壁與水管本體外側壁圍構減壓空間，減壓片形成連通於容置空間及減壓空間之間的通孔，出水孔連通於減壓空間及水道之間。本創作防止水管本體被土壤擠壓時不會被壓扁，確保水道及減壓空間提供水源流動空間，並防止出水孔及通孔被土壤堵住，且減低水源的水壓。
