Resin drainage ditch covers are usually located near our courtyards, around swimming pools, commercial areas and on both sides of roads. If the drainage efficiency and drainage effect of each drainage ditch cover can be effectively improved, drainage products can be effectively selected at each drainage cover. The following factors should be considered in the selection of resin drainage cover in different places:
Example of resin drain cover
Current: how much rainfall is expected
The first thing to consider is how much water we need to drain. The calculation method of water flow is very complicated. In 2006, the Ministry of Construction promulgated and implemented the "Outdoor Drainage Design Code."
1. Calculation of domestic sewage volume of urban residents
The domestic sewage quota and the comprehensive domestic sewage quota should be determined based on the local water consumption quota, combined with the level of the building's water supply and drainage facilities and the popularity of the drainage system. It can be used at 80% to 90% of the local water quota.
2. Industrial wastewater calculation
The determination of the amount of industrial wastewater and the coefficient of variation in the industrial zone should be based on the characteristics of the process and coordinate with the current national industrial water regulations.
The bearing capacity of the resin drainage cover: what type of vehicle is used in the area
When selecting the finished drainage cover, consider the objects passing through the drainage ditch cover, and their carrying capacity is different.
Acidic or alkaline water
At present, my country has serious environmental pollution, and the chemical composition of rainwater and domestic sewage is complex, especially industrial sewage. This sewage is very corrosive to the traditional concrete drainage cover plate, and the drainage ditch cover plate will be corroded and damaged after long-term use, causing serious impact on the environment. Resin concrete is the main material of the resin drainage cover plate and has good corrosion resistance.
Landscape requirements: overall landscape layout design of drainage pavement
When using resin drainage cover in urban construction or residential areas, greening is also a necessary condition for construction. The road drainage system should select drainage products suitable for urban construction according to the overall requirements of urban design. For most residential applications, a pre-tilted ditch drainage system with a slope of 0.7%-1% is sufficient.
Application of resin drainage cover
In summary, the design of resin drainage cover should fully consider drainage capacity, road traffic conditions, environmental landscape requirements and water quality requirements. Based on the above factors, the overall design idea of the resin drainage ditch cover is indoor drainage or kitchen drainage. The resin drainage cover plate of the stamping cover plate can be used to maintain the beauty and corrosion resistance of the ground. General road traffic pavement adopts linear drainage system design scheme. The U-shaped drainage cover plate that uses resin concrete as the ditch body material is combined with the cover plate that meets the bearing requirements of the road surface. This program has a very high cost performance. Special roads, such as airports, ports, large logistics centers, and other roads with high load-bearing requirements, can be designed with integrated drainage systems. Curb pavement can adopt curb drainage system design.
