Embodiment Construction

[0030] In order to further understand the present invention, the preferred embodiments of the present invention are described below in conjunction with examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0031] The application provides a method for preparing a colored permeable concrete floor, comprising the following steps:

[0032] 1) Plain soil is compacted to obtain a plain soil compaction layer;

[0033] 2) laying graded crushed stones on the plain soil compacted layer obtained in said step 1), to obtain a graded crushed stone layer;

[0034] 3) Laying a permeable geotextile on the graded crushed stone layer prepared in the step 2) to obtain a permeable geotextile layer;

[0035] 4) laying C25 permeable concrete on the permeable geotextile layer prepared in the step 3) to obtain a permeable concrete base;

[0036] 5) ...

Abstract

The invention discloses a preparation method of a colored pervious concrete ground. According to the preparation method, by virtue of a definite mix proportion and a strict construction flow, the strength requirement and water permeability requirement of the pervious concrete ground are guaranteed; by arranging pervious geotechnical cloth, rainwater can be the purified and filtered; and by pre-burying a drain pipeline in plain soil, the infiltration amount of rainwater infiltrated into a soil layer is adjusted, so that the damage caused by excessive rainwater to a soil layer foundation is avoided, the degree of the damage caused by water infiltration to a ground structure is decreased, the service life of the pervious ground is prolonged, and the utilization of rainwater resources and the protection of an ecological environment are benefited.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a method for preparing a colored permeable concrete floor. Background technique [0002] Permeable concrete, also known as porous concrete, sand-free concrete, and permeable floor, is a porous lightweight concrete made by mixing aggregate, cement, reinforcing agent, and water. It does not contain fine aggregate and is made of coarse aggregate. The surface is covered with a thin layer of cement paste and bonded to each other to form a honeycomb structure with uniform distribution of pores, so it has the characteristics of air permeability, water permeability and light weight. While permeable concrete firstly meets the strength requirements, it also needs to maintain certain through-holes to meet the water permeability requirements. Therefore, in addition to selecting suitable raw materials during preparation, it is also necessary to achieve simultaneous guarantee ...
