Preparation method of paving brick with guiding gutter

Abstract

The invention discloses a preparation method of a paving brick with a guiding gutter. The method comprises the following steps that paraffin is poured into a core mold structure of a drainage channel,and the inner portion of a core mold is provided with a metal thermal conductive wire; the core mold made from the paraffin is clamped in a mold frame,the distance between the very bottom end of the core mold and the very bottom end of the mold frame is 50-80 millimeters; a moderate bottom material and surface material are weighed in proportion,the bottom material and surface material in the moldframe are pressed,shaped and de-molded to obtain a green brick; the green brick is maintained; shot blasting is carried out on the surface of a surface layer of a maintained product; the core mold isheated to be de-molded,the metal thermal conductive wire in the core mold is heated,thereby cleaning away the paraffin core mold after the paraffin core mold is melted. The preparation method of the paving brick with the guiding gutter has the advantages that the paraffin mold replace a traditional mold,subsequent de-molding only needs heating for melt,so that the de-molding can be carried out quickly,the problem of difficult de-molding of the traditional mold is solved,the drainage channel penetrating through the inner portion of the paving brick can be arranged through the paraffin mold,andthe de-molding can be convenient.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing pavement bricks with water guide grooves. Background technique [0002] Urban rainwater is harmful and resource-intensive. With the acceleration of the urbanization process, the hard paved area in the city and the groundwater resources that are easily depleted by buildings cannot be compensated in a timely manner. The increasing density will cause the increase of surface rainwater runoff, the decrease of infiltration, the frequent occurrence of floods and the aggravation of damage. In developed countries, the research on the collection, utilization and resource utilization of urban rainwater started earlier, and a lot of achievements and experience have been obtained. Germany is one of the best countries in Europe to carry out rainwater utilization projects. In some areas of Germany, the use of rainwater can save 50% of drinking water. The use of rainwa...

Problems solved by technology

[0003] The current ground bricks are developing in the direction of high density and high strength, and their compressive strength is relatively high, but the biggest problem is that their water permeability is very poor. Even if there are blocks with good water permeability, their compressive strength cannot reach pavement requirements

At the same time, after long-term use of conventional permeable bricks, the surface and pores are easy to fall into various dirt to form blockages and cannot be automatically removed, thus losing the permeable effect and poor ecological effect.

Moreover, the requirements for supporting drainage facilities are also high during laying and use. If the drainage is not smooth after rain, it is easy to cause water accumulation, which is not conducive to sanitation, damages the environment, and creates obstacles for people to travel.
