PP water storage device for urban pavement rainwater self-infiltration purification

Abstract

The invention discloses a PP water storage device for urban pavement rainwater self-infiltration purification, and belongs the technical field of rainwater collection. The PP water storage device comprises a PP polypropylene water storage device body provided with an edge guard arm, a locate groove, a positioning boss, a plurality of connecting bosses and a plurality of connecting grooves are arranged on that edge guard arm. A main body of that water storage device is provided with an array of water storage tanks. A tank array consist of two rows of tank group, a lateral reinforce arm is arranged between that two row of water storage tank groups, a partition groove is arranged in the middle of the water storage tank. The partition groove separates the water storage tank into two water storage tanks. The two water storage tanks are provided with water collecting grooves, rainwater filtering cotton is arranged in the water collecting grooves, a permeating groove is arranged on the watercollecting grooves, a rotary permeating hole is arranged in the permeating groove, and a rotary groove and a scroll groove are arranged around the water storage tank. The invention has the advantagesof convenient installation, large bearing capacity, dismantling and migration, stable structure, not easy to cause deviation in the construction process, more stable use and favorable for large-scalepopularization and application.

Description

technical field [0001] The invention relates to a water storage device, in particular to a PP water storage device for urban pavement rainwater self-permeation purification, belonging to the technical field of rainwater collection. Background technique [0002] With the rapid progress of urbanization, there are more and more hardened urban roads, and the corresponding urban green area is also less and less. Most of the green areas, wetlands, ditches and other areas with the function of water conservation in the natural state have evolved into hardened roads. As a result, the city can only rely on the municipal pipe network for drainage when facing heavy rainfall. On the one hand, this drainage method has a higher design standard for the municipal pipe network; Because for most cities, the groundwater is generally short of water due to the large number of people who need to be supplied; in view of the above situation, my country first proposed the concept of "sponge city" in 20...
