Embodiment 1

[0007] Example 1, the river bed silt mainly comes from the lower reaches of the river bed, and the stock is huge. As the raw material of environmentally friendly permeable bricks, it generally does not need to be crushed again, and there are fewer impurities. Because the plasticity index of the raw material is low, improving the plasticity of the mud material will become adobe molding. key. In order to improve the plasticity of the mixed mud, it is necessary to remove the gravel and grass roots in the river bed silt sand, and control the particle size of the river bed silt sand below 2mm, and carry out aging treatment on the river bed silt sand, so that the water can be evenly immersed in the river bed silt sand ; Secondly, the aged river bed silt sand is mixed with sawdust, waste glass and water to obtain the required blank, in parts by mass: 55 parts of river bed silt sand, 10 parts of waste glass; 8 parts of sawdust, and the rest are water ; Then, the blank is molded to obt...

Embodiment 2

[0008] Embodiment 2, at first, get river bed silt sand and remove gravel and grass root wherein, control the particle of river bed silt sand below 2mm, and carry out aging process to river bed silt sand, make moisture immerse in the river bed silt sand evenly; Secondly , mix the aged river bed silt sand with sawdust, waste glass and water evenly to obtain the required blank, in parts by mass: 40 parts of river bed silt sand, 30 parts of waste glass; 5 parts of sawdust, and the rest are water; then , the blank is molded to obtain the required green body, and then dried; finally, the dried green body is put into a continuous kiln for firing, and the heating rate is controlled to be 3 degrees per minute, and the firing temperature is 1100°C.

Embodiment 3

[0009] Embodiment 3, at first, get river bed silt sand and remove gravel and grass root wherein, control the particle of river bed silt sand below 2mm, and carry out aging process to river bed silt sand, make moisture immerse in the river bed silt sand evenly; Secondly , mix the aged riverbed silt sand with sawdust, waste glass and water to obtain the required blank, in parts by mass: 45 parts of riverbed silt sand, 20 parts of waste glass; 15 parts of sawdust, and the rest are water; , the blank is molded to obtain the required green body, and then dried; finally, the dried green body is put into a continuous kiln for firing, and the heating rate is controlled to be 3 degrees per minute, and the firing temperature is 1000°C.

Abstract

Disclosed is a process for preparing a water-permeable brick by utilizing riverbed silted mud sands, which utilizes proper compositions of materials of riverbed silted mud sands and industrial waste glasses and fires the compositions into the environment-friendly water-permeable brick by high temperature through adding saw dust as a burning weight-loss agent. The intensity of a base can be improved by adding a sintering auxiliary agent to a mixed material in proportion. Utilizing the material to prepare the environment-friendly water-permeable brick can dispose the waste of riverbed silted mud sands in the nature, thereby governing the river way and changing waste into valuables, as well as having advantages of simple process and low cost. The water-permeable brick has good water permeability, water preserving capability and porosity; and has excellent surface hardness and intensity. The water-permeable brick can be widely applied to various aspects of urban roadway paving, and has functions of environment beautification and environment protection.

Description

technical field [0001] The invention relates to a method for preparing a water seepage brick, in particular to a method for preparing a water seepage brick by using riverbed silt and sand. Background technique [0002] At present, colored cement bricks or ceramic bricks are commonly used on sidewalks, squares, and hardened pavements in most cities in China. The pavements paved with these impermeable materials have brought many negative impacts on the ecological environment of the city. Due to the lack of water permeability and air permeability of the paved road, rainwater cannot penetrate into the ground, so that precious water resources cannot be circulated, the exchange and replenishment of groundwater is insufficient, and the surface plants are seriously short of water and difficult to grow normally; the impermeable road surface is difficult to exchange heat with the air , Water exchange, lack of ability to regulate urban surface temperature and humidity, resulting in ur...
