Water permeable concrete and water permeable concrete pipe for collecting rainwater
The invention discloses water permeable concrete and a water permeable concrete pipe for collecting rainwater. The water permeable concrete is composed of the following components in parts by weight: 80-120 parts of cement, 220-270 parts of stones, 70-100 parts of coarse sand, 7-13 parts of silica fume or coal fly ash, 6-13 parts of a vinyl acetate-ethylene copolymer emulsion, 0.1-0.3 part of a polyethylene fiber, 25-35 parts of water, and 0.8-1.3 part of a water reducing agent. The water permeable concrete pipe is formed by bonding an arc-shaped pipe wall prepared from the water permeable concrete with an ordinary concrete pipe wall; when in use, the ordinary concrete pipe wall is placed at the lower side, and the pipe wall prepared from the water permeable concrete is placed at the upper side. The prepared concrete pipe enables the water permeable coefficient to reach 1-2 mm/s, also can guarantee that the pore diameter is small and uniform, and effectively prevents blocking of pores.
