Embodiment 1

[0044] see Figure 1-2 and Figure 7 , a preparation process of self-draining concrete blocks, comprising the following preparation process steps:

[0045] S1. Prepare concrete pouring material: select cement, fly ash, fine sand, silica powder, bentonite, waterproofing agent, preservative, and coagulant with a certain mass ratio as raw materials, and mix and stir each raw material with water to obtain concrete pouring material;

[0046] S2. Prepare the pouring mold: the pouring mold is cleaned and dried in advance, and an opening forming device is embedded in the pouring mold, and the concrete pouring material obtained in S1 is introduced into the pouring mold, molded into the mold, and released after cooling. The block body 11 with self-drainage function is obtained by molding;

[0047] S3. Concrete block curing: put the block body 11 obtained in S2 into a curing box for carbon dioxide steam curing at a curing temperature of 40-60°C, cool down the cured block body 11, and f...

Abstract

The invention discloses a preparation process of a self-draining concrete block, which belongs to the technical field of the preparation process of concrete blocks. A hole forming device is arranged in the cavity of a pouring mold, and the concrete pouring material is introduced into the mold through the pouring port. After entering the cavity, the concrete pouring material covers the entire cavity and covers the end surface of the hole forming device. After demoulding, the obtained block body is separated from the cavity and the hole forming device, and the formed and hole forming The hole structure matching the hole forming device is beneficial to the drainage of the block body during use, and can quickly dredge a large amount of rainwater to a certain extent. The combination of tampering rods, after the concrete pouring material is poured, uses continuous and intermittent pneumatic control to realize the reciprocating expansion and contraction of multiple tampering rods, so as to vibrate the concrete pouring material and effectively improve the quality of concrete blocks.

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., with a wide r...
