In the process of water conservancy facilities construction, generally it uses a large size and area, the corresponding construction time is relatively long, reasonable and scientific construction scheme is particularly important. It is believed that the size of the filament geotextile has been cut at the scheduled time. If the construction area is relatively large, it is not recommended to use manual laying, although it is better to use large machinery. In addition, it should be noted that in the process of use, 30% of geotextile will be laid, and each layer of laying must be leveled and compacted. If the service life of filament geotextile is delayed fundamentally, anti-aging agent should be added in the production process. The effect of adding anti-aging agent can avoid the influence of sunlight, ozone and heat on the geotextile to a certain extent. Construction personnel can bury the upper layer with high water level or enough thick rock and soil, and necessary protection measures are also essential. Polymer waterproof materials laid together with geotextile should also avoid bonding. Appropriate construction technology must be adopted during construction. If feasible, appropriate coordination can be carried out according to the construction of waterproof board to achieve the effect of delaying the service life.
The cleaned foundation must be immediately backfilled or other work, and geotextile laying application. Often measure the quality of objects. Determine the water content of aggregate, adjust the mix proportion of concrete in time to ensure the concrete mixing. For construction in rainy season, pouring concrete in rainy days shall be avoided as far as possible. When concrete pouring is necessary for Geotextile application to speed up the progress, the water cement ratio can be appropriately reduced in light rain, and temporary canopy shall be set up on the warehouse surface to prevent rainwater from entering the concrete warehouse. If the surface mortar or concrete has not been initially set after rain, the construction can be continued after the cement mortar is paved, otherwise, the treatment shall be carried out according to the requirements of the working joint, and the concrete pouring shall be stopped in case of heavy rain. During the filling construction in rainy season, effective measures should be taken for drainage of the stockyard to reduce the waiting time after the rain as far as possible; during the construction after the rain, measures such as turning and re pressing soil materials should be taken to ensure the best moisture content of the filling materials; during filling, slope form should be made on the surface of the compacted layer to facilitate drainage and other measures. If necessary, the surface layer shall be cleaned up again, the geotextile shall be used and the construction shall be resumed in time after the quality inspection is qualified.
The service life of filament geotextile can be expected, but if the relevant effective measures are taken in the process of use, the service life can also be extended. The inherent polymer material of this material will inevitably appear aging phenomenon. Experts remind construction personnel to pay attention to the construction conditions when laying filament geotextile, and the most important thing is whether the construction cost can use the current market price of this material. Whether the application scope and effect of this material in this area can be popularized, or investigate whether there are any emergencies in the construction process that prevent the construction progress or affect other projects.
