Preparation process of self-drainage concrete block

Abstract

The invention discloses a preparation process of a self-drainage concrete block, and belongs to the technical field of preparation processes of concrete blocks. A trepanning forming device is arrangedin a cavity of a pouring mold, and after a concrete pouring material is introduced into the cavity through a pouring port, the concrete pouring material covers the whole cavity and wraps the end faceof the trepanning forming device. After demolding, the obtained block body is separated from the cavity and the trepanning forming device. A trepanning structure matched with the trepanning forming device is formed on the block body, so that water drainage of the block body in the using process is facilitated, and a large amount of rainwater can be rapidly dredged to a certain extent. Meanwhile,through cooperation of a pneumatic mechanism and multiple crunching rods on a cavity opening die roller, after the concrete pouring material is poured, pneumatic control is continuously and intermittently conducted, the multiple crunching rods stretch out and draw back in a reciprocating mode back and forth, and therefore a compaction effect on the concrete pouring material is achieved, and the quality of the concrete block is effectively improved.

Description

technical field [0001] The invention relates to the field of preparation technology of concrete block, more specifically, relates to a preparation technology of self-draining concrete block. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Generally, it refers to the use of cement as cementitious material, sand and stone as aggregates, and water (may contain admixtures and admixtures) It is mixed and prepared according to a certain proportion, and the cement concrete obtained by mixing is widely used in civil engineering construction. [0003] At present, in the field of civil engineering construction, concrete blocks are widely used to build subgrade surfaces. Pavement bricks are a kind of pavement material, mainly used for laying concrete pavements such as urban road sidewalks, urban squares, and ground engineering blocks and slabs. Etc., a wide range ...

AI Technical Summary

Problems solved by technology

Most of the concrete blocks we use now are closed structures. When encountering heavy natural rainfall, it is difficult to dredge the rainwater quickly in a short period of time, so that there is more water on the road surface. Good for road cleaning
