现浇衬砌渠道的结构型式有很多种,考虑到渠道沿线土质、气温、地下水位、渠道流量及便于施工等因素,选定现浇渠道的结构型式为等厚度梯形单式断面。渠道现浇衬砌以其防渗效果好、使用寿命长、施工质量便于控制、外表美观等特点,在渠道防渗方面深受青睐。文章从结构型式、土方开挖、土方回填、混凝土原材料及配合比、现浇混凝土施工工艺等方面介绍现浇混凝土衬砌渠道施工技术。
In-situ lining channels of the structure there are many types, taking into account the soil along the channel, temperature, groundwater level, channel flow and ease of construction and other factors, the selection of cast-in-site structure of the same thickness trapezoidal single cross-section. In-situ lining channel with its impermeable effect, long life, construction quality control, appearance and other characteristics, impermeable in the channel by the popular. The article introduces the construction technology of cast-in-place concrete lining channel from the aspects of structure type, earth excavation, earthwork backfill, concrete raw material and mix ratio, cast-in-place concrete construction technology and so on.
