    The Coastal Channel Lays The Nano Sheets To Prevent The Foundation From Sinking.

    Recently, in the coastal section of the east coast of Quanzhou, Fujian, workers laid the long white cloth on the foundation of the large coastal passageway, then covered the soil with a layer of "white cloth".

    This scene has repeatedly led passers-by to be curious.

    In fact, this "white cloth" is a kind of nano synthetic material, which is called high strength geotextile. It is used to improve the overload preload of the road section and prevent the soft foundation subsidence of the large coastal passageway. Generally it is laid in the retaining wall within the sea. The width is about 40 meters, and the different sections generally lay 1 to 5 layers.

    Chen Qingchun, the person in charge of the construction site, said that at present, the 4 sections of the large coastal road need to lay high strength geotextiles have completed the laying of a section, and the laying of other sections has also been completed. The construction workers can lay about 60 meters long and 40 meters wide a day.

    If we lay multi-layered geotextiles, we usually fill the first floor with 5 centimeter thick sand, and then lay second layers.

    In this way, the foundation can be continuously thickened, and the overloading and preloading capacity of the foundation will be improved, so as to prevent the wind and waves from crossing the retaining wall and attacking the foundation, and the lower limit and uneven condition of the foundation will occur.

    According to Liu Yingzhen, chief engineer of Binhai Road construction headquarters in Quanzhou, the total length of the main section of the coastal section is 6.91 km, of which 5.88 km is needed for the construction of high strength geotextiles. The laying work is expected to be completed next month, and the whole coastal large channel project will be completed in July next year.
