A kind of preparation method of high-strength permeable concrete

Abstract

The invention belongs to the technical field of permeable concrete preparation, and in particular relates to a method for preparing high-strength permeable concrete. The desilting device used in the method comprises a body, a feeding port, a machine cover and a controller; plate; the inclined plate is installed inside the body, the end of the inclined plate close to the feed port is inclined upward, the interior of the inclined plate is provided with a through hole, and the end of the inclined plate away from the feed port is fixedly connected with a mounting plate; the cross-section of the mounting plate The shape is L-shaped; the desilting device used in the preparation method of high-strength permeable concrete according to the present invention is arranged by the push plate, so that the push plate can remove the stones on the inclined plate under the mutual cooperation of the reciprocating motor and the sliding rod. Kneading makes the soil on the surface of the stone fall. By setting the resistance wire, the resistance wire can bake the stone on the inclined plate, so that the soil on the surface of the stone is dry, thereby accelerating the falling rate of the soil and improving the cleaning of the stone by the push plate. Effect.

Description

technical field [0001] The invention belongs to the technical field of permeable concrete preparation, in particular to a preparation method of high-strength permeable concrete. Background technique [0002] The structure of permeable concrete includes cushion layer, base layer and surface layer. Each layer has different requirements for the size of the stone. For the surface layer, the diameter of the stone is required to be 5-10mm, and the mud content in the stone should be less than 1%. When the mud content of the stone is high, the strength of the concrete will be reduced, which will cause the concrete to crack and produce sand. The method of water washing, but the soil is easy to adhere to the stone when it encounters water, thereby reducing the cleaning effect of the water flow on the soil, and the water flow cleaning requires constant water changes to maintain the cleaning effect of the water flow on the stone, thus wasting a lot of water resources.

[0002] The structure of permeable concrete includes cushion layer, base layer and surface layer. Each layer has different requirements for the size of stones. For the surface layer, the diameter of the stones is required to be 5-10mm, and the mud content in the stones should be less than 1%. When the mud content of the gravel is high, it will lead to a decrease in the strength of the concrete, causing problems such as cracking and sanding of the concrete. Therefore, desilting the gravel is an indispensable work before production. The traditional method of desilting the gravel often uses The method of washing with water, but the soil is easy to adhere to the stones when it encounters water, thereby reducing the cleaning effect of the water flow on the soil, and the water flow cleaning requires constant water changes to maintain the cleaning effect of the water flow on the stones, thus wasting a lot of water resources

[0003] In the prior art, there are also some technical solutions on high-strength water-permeable concrete and its preparation method. For example, a Chinese patent with application number CN201810976607.1 discloses high-strength water-permeable concrete and its preparation method, including the following components: cement , reinforced aggregate, water-permeable aggregate, reinforced fiber, toughening agent, water reducer, water; the reinforced aggregate includes gravel and high-strength ceramsite; the water-permeable aggregate includes zeolite and shell particles; the reinforced fiber Including carbon fiber and bamboo fiber; this technical solution increases the antibacterial performance of concrete and improves the durability of concrete by adding bamboo fiber and shell particles; however, this technical solution does not consider the high mud content of stones in concrete, which reduces the strength of concrete. Causes problems such as cracking and sanding in concrete, which in turn causes limitations of this technical solution
