An ecological permeable pavement brick and its production process

Abstract

The invention relates to the technical field of building blocks, in particular to an ecological permeable pavement brick and a production process thereof. The ecological permeable pavement brick comprises a permeable layer, a surface layer and a permeable layer; each layer in the brick body is formed by vibrating and extruding through a vibration forming machine; the vibration forming machine comprises a machine body, a vibration table, a mold, a pressing plate and a controller. Due to the fact that raw materials of the brick body are subjected to extrusion forming to ensure that aggregate isevenly distributed, the brick body structure subjected to vibration forming forms a one-way surface layer and a water permeable layer, a water storage layer structure cannot be obtained, and the ecological water storage effect of the ecological water permeable pavement brick is lost; therefore, the operation of the vibration forming machine is adjusted through the arranged controller; according tothe ecological permeable pavement brick, coarse and fine aggregate particles are layered again by the brick body in the mold under low-frequency vibration, pores among the coarse aggregate particlesare used as a water storage layer of the brick body, and the'heat island effect 'of a city is weakened by evaporation of water in the water storage layer, so that the ecological adjustment effect of the ecological permeable pavement brick is achieved.

Description

technical field [0001] The invention relates to the technical field of building blocks, in particular to an ecological permeable pavement brick and a production process thereof. Background technique [0002] With the advancement of urbanization in the country, the problem of "heat island effect" caused by hardened roads in cities has intensified, affecting the urban ground ecosystem, making the atmospheric water cycle unable to effectively replenish groundwater; and the emergence of ecological permeable bricks effectively solves the problem. Problem, the porous structure of the permeable brick body makes it have rain and snow permeability; for the introduction of ecological permeable pavement bricks, please refer to: Shi Junhui, the production of permeable bricks and the design of ecological permeable ground system [D], Huainan: Anhui University of Science and Technology ,2017. [0003] At present, the production technology of permeable bricks made of various materials is b...

Problems solved by technology

[0004] There are also some technical solutions on ecological permeable pavement bricks and their production processes in the prior art. For example, a Chinese patent with application number 2018107466265 discloses a high-strength dust-proof ecological permeable pavement brick and its production process, including the following Raw materials: river sand, iron and steel copper slag, tailings slag or tailings powder, cement and others; its production process includes: S1, setting the ratio of various raw materials in the mixing system and stirring; S2: compressing the materials through the main engine Forming and demoulding is completed, after demoulding, the product is transported to the delivery system through the plate supply machine; S3: transport the formed product to the curing kiln for curing; S4: send the product out of the kiln to the surface layer machine Carry out the finishing treatment of bricks; S5: The products after finishing treatment are transported to the palletizer for stacking, and then packed out of the warehouse after palletizing; this technical solution can improve the water permeability efficiency, compressive and flexural strength of pavement bricks, At the same time, it can prevent the pores of permeable pavement bricks from being clogged and improve the color of the brick surface; however, the water storage characteristics of the ecological permeable pavement brick body in this technical solution have not been effectively realized, and the water stored in the brick body cannot be effectively evaporated to alleviate the problem. The problem of the urban "heat island effect"
