一. Functional differences
1、Water storage plate: A water storage plate is a plate equipment that can collect, store and control the flowing medium. It is generally installed at the bottom of areas such as containers, ponds, ditches or roads, and is used to collect the overflow when the fluid level is lowered, and to discharge this water downstream or to specific areas. The water storage board not only has drainage function, but also has water storage capacity, which can provide sufficient water and oxygen for plant growth.
2、Drainage board: Drainage board is a new type of drainage geomaterial that can quickly drain excess water and reduce the problem of water accumulation. It is made of polyethylene ( HDPE） Or polypropylene ( PP） Made of plastic materials, it has very good drainage performance and compressive strength. Drainage boards can be used in waterproofing and drainage systems of infrastructure such as basements, roof gardens, roads, bridges, and soil drainage improvement in garden landscapes.
二. Structural characteristics
1、Water storage board: The water storage board is made of high-density polyethylene ( HDPE） Or polypropylene ( PP） It is made of environmentally friendly materials such as heating, pressurization and shaping, and has the characteristics of high compressive strength, light weight, load resistance, simple construction, environmental protection and long life. The inside of the water storage plate is designed with a three-dimensional space support structure, which can form a drainage channel and a water storage space.
2、Drainage board: The drainage board is made of polystyrene ( HIPS） Or polyethylene ( HDPE） As raw materials, it is stamped into conical projections or convex points (or hollow cylindrical porous holes) of stiffeners. The width and length of the drainage board can be customized according to specific needs to adapt to different application scenarios.
三. Application scenarios
1、Water storage board: The water storage board has a very good water storage function. It can be used in roof greening, underground car roof panel greening, city squares, golf courses, sports fields, sewage treatment plants, public building greening and other fields. Its ability to provide a steady source of moisture for plants also reduces irrigation needs and reduces maintenance costs.
2、Drainage board: Drainage board has efficient drainage performance and compressive strength, and can be used in many fields such as architectural engineering, municipal engineering, and garden landscape. It can prevent soil water accumulation, improve soil drainage conditions, promote plant growth, and reduce structural damage and potential safety hazards caused by water accumulation.
四. Performance comparison
In terms of drainage efficiency, drainage boards drain water faster and can be used in projects that require rapid drainage; The water storage board pays more attention to the water storage function and can regulate soil moisture to a certain extent. In terms of compressive strength, both of them have higher compressive performance, but the water storage plate may have stronger overall stability due to the internal structural design. During construction, drainage boards are more convenient and simpler.
As can be seen from the above, there are many differences between the water storage board and the drainage board in terms of function, structure, application scenarios, etc. In practical applications, it is necessary to select appropriate geotechnical materials according to specific needs and scenarios to ensure the quality and effect of the project.
