Colored pervious brick body for farmland drainage ditch

Abstract

The invention discloses a colored pervious brick body for a farmland drainage ditch. The pervious brick body is of a two-layer structure including a colored pervious layer and a reverse osmosis waterbase layer; the colored pervious layer is formed by mixing and pressing porous clastic rock, ceramsite, modified epoxy resin, white cement, natural ore pigments and water; the thickness of the coloredpervious layer is 3 to 7cm; the aggregate gap rate is not lower than 30 percent; the reverse osmosis water base layer is formed by mixing and pressing the porous clastic rock, the white cement, quartz sand and water, and is arranged under the colored pervious layer; the thickness of the reverse osmosis water base layer is 1 to 2cm; the aggregate gap rate is not higher than 18 percent. The degressive gradient relationship between the interlayer thickness and the aggregate gap rate of the colored pervious layer and the reverse osmosis water base layer is utilized; on the premise of ensuring thephysical strength of the brick body, the pervious performance and the water retention performance are improved; moisture can be slowly permeated through a soil layer.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a colored permeable brick body for farmland drainage ditches. Background technique [0002] Permeable brick is a composite structure made of aggregate and binder. Generally, river sand, slag waste, gravel, etc. are used as aggregate, and cement is used as binder. The brick itself has poor water permeability, mainly relying on The gaps between adjacent bricks are infiltrated and drained. The existing technology has initially solved the problem of poor water permeability of permeable bricks. However, the surface soil cannot quickly drain and dredge a large amount of permeated water in a short period of time. When walking in rainy days, there will still be a lot of water. Backlogged water splashes or reverses osmosis through pavement crevices, causing inconvenience and causing soil nutrients to be lost. Therefore, how to produce a kind of permeable brick with certain wat...

The patent application number is CN201710539266.7, which discloses a recycled aggregate ecological permeable brick and its production process. The raw embryo is made of straw, Malan loess, coarse aggregate and natural auxiliary materials, and then carbonized at a high temperature of 500 ° C to obtain The permeable brick has a certain water storage performance, but the physical strength of straw and Malan loess is low, and the flexural coefficient and compressive performance of the obtained permeable brick cannot be guaranteed, and the production process consumes a lot of energy
