渠道施工经常运用的材料就是混凝土,其有着高稳定性与方便操作的特点,得到各类工程的广泛使用。在中国农业发展当中,重要的一环就是灌区混凝土防渗渠道。在实际使用过程中,各种环境因素会影响灌区混凝土,以致产生冻胀,进而影响灌区混凝土防渗渠道的实际使用能力。从灌区混凝土防渗渠道概况、灌区混凝土防渗渠道冻胀破坏类型、导致出现灌区混凝土防渗渠道冻胀的因素、应对灌区混凝土防渗渠道冻害的策略等四个方面进行阐述,希望可以有助于应对灌区混凝土防渗渠道冻胀问题。
Channel construction often used material is concrete, which has the characteristics of high stability and easy operation, has been widely used in various projects. An important part of agricultural development in China is the concrete seepage prevention channel in irrigation areas. In actual use, various environmental factors will affect the concrete irrigation, resulting in frost heave, thus affecting the actual use of concrete anti-seepage channels irrigation capacity. From four aspects: the general situation of concrete seepage prevention canal in irrigation district, the type of frost heave destruction of concrete seepage prevention canal in irrigation district, the factors causing frostbite of concrete seepage prevention canal in irrigated area and the strategy of dealing with frostbite damage of concrete seepage control canal in irrigation district, and so on. To deal with the frost heaving problems of concrete seepage prevention canal in irrigated area.
