Three dimensional composite drainage network It can be used in water conservancy projects, municipal roads, landfills and other fields. So, what is its lap width?
1. Three-dimensional Composite drainage network Basic overview of
The three-dimensional composite drainage net is made of acupuncture Non-woven geotextile It is compounded with three-dimensional geonet core, and has very good drainage, ventilation and isolation functions. Its structural characteristics allow water to pass through quickly, preventing soil erosion and water pollution. It also has high compressive strength and anti-aging properties, and can adapt to various complex geological and climatic conditions.
The width of the three-dimensional composite drainage network is generally 100 cm To 200 cm， The thickness is 6 cm To 20 cm Between. Wide range of compressive strength from 250 kpa To 1000 kpa It can meet the needs of different projects. Products of other specifications and performances can also be customized depending on specific engineering requirements.
2. Selection and influence of overlap width
In the installation process of three-dimensional composite drainage network, the choice of overlap width has an important influence on its drainage effect. Generally, the overlap width should be 10 cm To 20 cm Between. However, this value is not fixed, but should be flexibly adjusted according to the specific engineering environment and requirements.
1、Water quality factors: The quality of water directly affects the blockage of the drainage network. If the water quality is poor and contains a lot of impurities and particulate matter, it is necessary to choose a large lap width to ensure that the drainage channel is not blocked.
2、Terrain Conditions: Terrain also has an important influence on the drainage effect. On steep terrain, in order to drain water more efficiently and prevent breakage of the drainage net caused by scouring of the water flow, a larger lap width can be selected.
3、Rainfall: The amount of rainfall is also one of the factors to consider when choosing the width of the lap. In areas with heavy rainfall, if you want to keep the drainage channel unblocked, you must choose a larger overlap width to prevent the drainage channel from being over-blocked.
4、Engineering requirements: The selection of overlap width should also be carried out according to specific engineering requirements. Including ground hardening degree, building height, displacement requirements and other aspects. In engineering, these factors should be considered comprehensively to determine the most suitable lap width.
3. Construction precautions
1、Construction preparation: Before construction, the site should be cleaned and cleaned to ensure that there are no debris such as floating soil, stones and sharp objects, otherwise the laying effect of the drainage network will be affected.
2、Connection method: The connection method of the three-dimensional composite drainage net is nylon buckle or plastic connecting belt. When connecting, ensure that the connection is firm and tight to avoid water leakage.
3、Water guide block installation: A water guide block should be installed at the retaining wall or parapet wall, which can collect rainwater and drain water away from the drain hole. The installation length of the water guide block should be determined according to the width of the drainage site to ensure the drainage effect.
It can be seen from the above that the selection of the overlap width of the three-dimensional composite drainage network should comprehensively consider multiple factors such as water quality, topography, rainfall and engineering requirements. By reasonably selecting the overlap width, the stability and reliability of the drainage effect of the drainage network can be ensured, and the engineering quality and service life can be improved.
