时必须要给予重视，由于透水砖铺装底层就好比房子建筑最重要的地基，地基假如不稳，房子的安全系数就没有保证。 Attention must be paid to the construction of the permeable brick ground floor , because the permeable brick floor is like the most important foundation of a house building. If the foundation is unstable, the safety factor of the house is not guaranteed.
Therefore, the following requirements should be met during the construction of the permeable brick floor:
1. The crushed stone grading and water consumption of the pervious cement stabilized crushed stone bottom should meet the planning requirements. The cement content should meet the planning requirements of the mix, and the compaction operation must be completed before the cement is finally set.
2. The cooperation ratio of permeable cement concrete construction shall meet the planning requirements. A laboratory trial should be carried out, and the cooperation ratio of low cement consumption, strength and water permeability that meets the planning requirements should be selected according to the experimental results.
3. The bottom layer of the permeable cement concrete should satisfy the requirements of the plan, and the compaction operation must be completed before the cement finally sets.
4. The strength of the bottom layer should meet the planning requirements, and the construction of the permeable cement stabilized crushed stone and the permeable cement concrete should be carried out on the same day.
The ground floor is laid, and it is very helpful for the later maintenance of permeable bricks, and it can extend the service life of the project without rebuilding in a short time, saving financial resources and manpower.
