Construction technology for secondary transformation of water-permeable and water-storage sponge city

The invention discloses a secondary transformation water-permeable and water-storage sponge city construction technology, relates to the technical field of sponge city construction, and provides the following scheme that the secondary transformation water-permeable and water-storage sponge city construction technology comprises the following construction processes that a horizontal fixed point of an original cast-in-place reinforced concrete floor is cleaned up through a high-pressure water gun; structure water seepage treatment and gabion filling; the 75pc plastic pipe is divided into two parts, the two parts face downwards and are placed into the gabions to serve as water permeable grooves, the distance between the two parts is 2 meters, and the 110pc plastic pipes on the periphery are connected and led to a water storage pool. According to the technical scheme, energy dissipation gravel serves as a permeable layer to be filled in a gabion, a 75pc plastic pipe which is divided into two parts is arranged in
