In engineering, geotextiles are related to Drainage plate It is a commonly used geotechnical material and can be used in foundation treatment, waterproofing isolation, drainage and other projects.
1. Characteristics and functions of geotextiles and drainage boards
1、Geotextile: Geotextile is mainly woven from polymer fibers such as polyester and polypropylene, and has excellent tensile strength, elongation, corrosion resistance and aging resistance. It has the functions of waterproofing, isolation, reinforcement, anti-filtration, etc., which can protect underground structures and pipelines from soil erosion and infiltration, and improve the overall stability of the project.
2、Drainage board: The water permeability of the drainage board is very good. It is generally made of polymer materials and is designed with drainage channels or bumps inside to achieve rapid drainage. It can discharge excess water from the soil, reduce the groundwater level, improve the soil environment, and also alleviate problems such as foundation settlement caused by water accumulation.

2. Consideration of construction sequence
1、Foundation drainage requirements: If the project has clear requirements for foundation drainage, especially when external drainage is used to guide ground water flow to underground drainage facilities, it is recommended to lay drainage boards first. The drainage board can quickly remove the moisture in the foundation, provide a dry and stable working environment for the geotextile, and better exert the waterproofing and isolation functions of the geotextile.
2、Waterproof isolation requirements: If the project has high requirements for waterproof isolation, such as underground structures to prevent groundwater infiltration, it is recommended to lay geotextile first. Geotextiles are very waterproof and can isolate groundwater from direct contact with underground structures, protecting underground structures from erosion.
3、Construction conditions and efficiency: In actual construction, construction conditions and efficiency should also be considered. Under normal circumstances, geotextile construction is relatively simple, easy to cut, splice and fix. When the drainage board is laid, it is necessary to ensure that the drainage channel or bump point is oriented correctly, and necessary connection and fixing work should be carried out. Therefore, when conditions permit, the construction of geotextile can be completed first, so as to facilitate the subsequent laying of drainage boards.
As can be seen from the above, the construction sequence of geotextile and drainage board should be determined according to the specific engineering requirements and construction conditions. Under normal circumstances, if drainage is the main purpose, it is recommended to lay drainage boards first; If waterproofing isolation is the main purpose, it is recommended to lay geotextile first. During the construction process, it is necessary to strictly follow the construction specifications to ensure the correct laying, connection and fixation of geotextile and drainage board to ensure the quality and effect of the project.
