Water-retention, water-permeation and water-filtration paving brick and manufacturing method thereof

Abstract

The invention discloses a water-retention, water-permeation and water-filtration paving brick and a manufacturing method thereof. The paving brick is prepared from the following ingredients in parts by weight: 100 parts of waste ceramsite, 5 to 8 parts of river sand, 5 to 8 parts of flint clay, 5 to 6 parts of pore forming agent, 5 to 8 parts of binder, 2 to 5 parts of fluxing agent, 6 to 9 parts of kaolin, 1 to 3 parts of glaze and 2 to 5 parts of water, wherein the ingredients are sintered into the brick. The manufacturing method comprises the steps of smashing, distributing material, mixing, manufacturing a green body and sintering. The paving brick prepared by the method has water-retention, water-permeation and water-filtration functions, can filter rainwater repeatedly to remove impurities in the rainwater, further can collect a part of rainwater, achieves a rainwater retention effect, reduces municipal drainage pressure and relieves a heat island effect.

Description

technical field [0001] The invention relates to a building material technology, in particular to a water-retaining permeable water-filtering paving slab brick and a manufacturing method thereof. Background technique [0002] At present, most of the hardened ground in the city is paved with impermeable materials, such as granite, marble, sleeve brick, cement and asphalt. These hardened grounds have a certain compressive strength and beautify the city to a certain extent. [0003] However, due to the non-absorbent and impermeable properties of these hardened surfaces, while bringing convenience, it also brings a series of problems to the life and living environment of urban residents, such as: [0004] (1) When it rains, the rainwater cannot infiltrate into the ground, thus forming stagnant water on the ground, causing inconvenience to people's travel; at this time, the rainwater can only be drained through the drainage pipes, which undoubtedly increases the burden on the urba...

AI Technical Summary

Problems solved by technology

[0004] (1) When it rains, the rainwater cannot penetrate into the ground, thus forming ponding on the ground, causing inconvenience to people's travel; at this time, the rainwater can only be drained through the drainage pipes, which undoubtedly increases the burden on the urban drainage facilities, and the rainwater passes through Drainage pipes are concentratedly discharged into rivers, and the groundwater in the land below the urban road surface cannot be replenished, which will easily cause land subsidence and soil compaction, and further aggravate the city's drought and water shortage problems.
