Curing geotextiles are divided into polyester filament curing geotextiles and short-filament curing geotextiles.
Curing geotextiles are divided into polyester filament curing geotextiles and short-filament curing geotextiles. The full name is broken chemical fiber needled non-woven curing geotextile and polyester polyester yarn de-glued needled non-woven curing geotextile. The specifications and models of the geotextile vary from 100 grams to 1000 grams per square meter, and the price ranges from 0.6 yuan to 7 yuan per square meter. Different.
New maintenance geotextile inspection project: The maintenance geotextile products are inspected according to the maintenance geotextile industry standard GB/T17638-2008. The test index values of the curing geotextile are quality and elongation at break, CBR cracking compressive strength, tearing compressive strength, equivalent circuit diameter, vertical water permeability, thickness and other index values.
The slope protection of the conservation geotextile slope is determined on the conservation geotextile. The error of the straight line adjacent to the vertical connector shall not be higher than 1 meter. Non-prevention cloth can be used for water conservancy and hydropower engineering, river embankment, road engineering, airport, engineering projects, housing construction and green ecological ecological environment protection new maintenance geotextile project, maintenance geotextile such as overprotection, sewage pipeline, maintenance geotextile protection, overhaul , Engineering reinforcement, etc.
The maintenance of geotextile is based on the type of soil: soil layer, gravel, and clay at the bottom. There is no need to stretch it too tightly, and some remaining sinking value of 1.50 should be prepared in advance. The vertical osteoarthritis should be separated from the toes, and the sight glasses should be above 1.5 meters. They should put it on the plane, maintain the geotextile and support a steep slope. When the conservation geotextile is used to pave slopes, the thin, soft, fully transparent sheet of the conservation geotextile plastic film should be parallel to the slope line.
The cracks of the curing geotextile concrete are caused by the bitumen overlay stress caused by the large deviation of the old concrete overall surface at the joint or the periphery of the gap, including the level deviation caused by the change of temperature and environmental humidity, and its traffic Vertical cutting offset caused by travel load. The former one causes the bitumen overlay layer to cause concentrated tensile stress or gaps, and the latter one causes the bitumen overlay layer above the connection point to bear relatively large bending tensile stress and shear stress.
The compressive strength test of the maintenance geotextile is generally based on whether the maintenance geotextile will collapse under load. In order to better prevent the error of the test results, the maintenance geotextile of different sizes can be tested and observed under the same premise. The maintenance geotextile should be tested with CRE compressive strength tester.
