Water permeable brick for sponge city and preparation method thereof

Abstract

The invention discloses a water permeable brick for a sponge city and a preparation method thereof. A water permeable brick main body comprises an upper surface course and a lower surface course; a placing groove, in which a luminous block is embedded, is formed in the end surface of the upper surface course; raw materials of the lower surface course are respectively conveyed into a molding machine after being stirred; raw materials of the upper surface course are conveyed into a molding machine, in which the raw materials of the lower surface course are laid, after being stirred; the raw materials of the lower surface course and the raw materials of the upper surface course are respectively pressed into a brick body I and a brick body II; a first groove is formed in one end, connected with the brick body II, of the brick body I; the placing groove comprises a right groove and a left groove; the right groove is next to the first groove and positioned on the brick body I; convex blocksare respectively arranged on the two sides of the first groove; a second groove is formed in one end, connected with the brick body I, of the brick body II; the left groove is next to the second groove and positioned on the brick body II; first positioning grooves matched with the convex blocks are respectively formed in the two sides of the second groove; the first groove and the second groove are symmetrically formed; and the first groove and the second groove are spliced with each other to form a vertical mounting groove with a water inlet pipe. The water permeable brick for the sponge cityhas the advantages of better water permeability and better strength.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable brick used for a sponge city and a preparation method thereof. Background technique [0002] At present, with the development of the economy and the acceleration of the pace of urban modernization, most cities have experienced the lack of groundwater resources and the heat island effect. Studies have found that these problems are related to the continuous destruction of natural soil vegetation by buildings and various types of impermeable water in urban construction. It is related to the bottom surface coverage. The proportion of impermeable ground in many cities in China has exceeded 70%, which has changed the original permeability properties of the natural ground and greatly damaged the ecological environment, especially for cities with a lot of rain. If the ground is used Cement, asphalt, marble and other non-permeable materials lay the ground. When it r...

[0002] At present, with the development of the economy and the acceleration of the pace of urban modernization, most cities have experienced the lack of groundwater resources and the heat island effect. Studies have found that these problems are related to the continuous destruction of natural soil vegetation by buildings and various types of impermeable water in urban construction. It is related to the bottom surface coverage. The proportion of impermeable ground in many cities in China has exceeded 70%, which has changed the original permeability properties of the natural ground and greatly damaged the ecological environment, especially for cities with a lot of rain. If the ground is used Cement, asphalt, marble and other non-permeable materials lay the ground. When it rains, the impermeable ground completely prevents the rainwater from directly penetrating into the ground. Increased the burden on urban
