Guide hole water-permeable brick as well as brick machine mold and method for preparing same

Abstract

The invention discloses a guide hole water-permeable brick as well as a brick machine mold and a method for preparing the same and belongs to the technical field of production of guide hole water-permeable bricks. The produced guide hole water-permeable brick comprises two parts including a guide hole water-permeable structure layer and a porous water-permeable surface layer. Guide hole needles are located at the lower part of an upper mold of a brick making machine, and any ordinary brick mold molds provided with the additional guide hole needles can be used for producing the guide hole water-permeable bricks. The thickness of the guide hole water-permeable structure layer is 80%-90% that of a test piece and the guide hole water-permeable structure layer mainly bears external load of thetest piece; the porous water-permeable surface layer mainly plays a role in preventing blockage of a guide hole water-permeable base layer. The mold is mainly used for forming of the guide hole water-permeable brick, the guide hole water-permeable structure layer is prepared in a manual hole forming manner, forming of ineffective pores is avoided, the problems that conventional water-permeable concrete has incompatible strength and water permeability, and the strength and the water permeability of the produced water-permeable brick are higher.

Description

technical field [0001] The invention relates to a guide hole permeable brick and a preparation process thereof, belonging to the technical field of guide hole permeable brick production. Background technique [0002] While the existing concrete pavement brings convenience to travel, it also brings a series of problems such as: (1) urban waterlogging is prone to occur; (2) groundwater cannot be replenished in time, resulting in a drop in groundwater level; (3) Produce "heat island effect" and so on. In order to solve the above problems, my country vigorously promotes the construction of sponge cities. my country's GB / T50378-2006 "Evaluation Standards for Green Buildings" stipulates that the ratio of the permeable floor area of ​​public buildings and residential buildings should not be less than 40% and 45%, respectively. The permeable brick pavement not only solves the above problems, but also has the functions of sound absorption and noise reduction. [0003] In recent ye...

Problems solved by technology

However, the traditional permeable concrete pavement still has two problems of low strength and poor water permeability. The main reason is that the water permeability and strength of the traditional permeable pavement are contradictory. The current technology cannot achieve the best state of both at the same time. This is One of the most important reasons restricting the development of pervious concrete pavement
