一、概况应用土工织物处理渠道滑坡,是利用土工织物的过滤透水性,将渠坡土中的侧向渗流,通过土工织物排入渠道中,从而达到固结边坡土体,加强边坡稳定之目的。秦皇岛市昌黎县引滦灌区七八年动工,八四年峻工,总投资八百多万元。设计过水流量9.5立米/秒,灌溉面积六万多亩。该灌区二分干挖方渠段设计流量2米~3/秒,渠道两侧均是水稻田。由于土质较松散,渗透系数大,放水运用后渠底淤积和渠坡坍塌日趋严重,输水能力
First, the general application of geotextile treatment of landslides, is the use of geotextile filtration permeability, the lateral flow of slope slope soil through the geotextile into the channel, so as to consolidate the slope of the soil, to strengthen the stability of the slope The purpose. Qinhuangdao City, Changli County, Luan River irrigation started in 1978, completed in 1984, a total investment of more than eight million yuan. Designed to flow 9.5 liters / sec, irrigation area of more than 60,000 mu. The irrigated area Duanqu Drainage canal design flow of 2 m ~ 3 / s, both sides of the channel are paddy fields. Due to loosen soil and large permeability coefficient, siltation of canal bottom and drainage slope collapse after drainage are more serious, water conveyance capacity
