传统上对梯形渠道的衬砌多采用预制平面实心水泥板，而预制槽型水泥板与之相比，具有重量轻、用料省、输水能力强、防渗效果好等特点，因此，推荐使用格型水泥板衬砌渠道。以北京市双桥农场污水灌区渠道衬砌为实例，介绍了槽型水泥板的设计、铁模板的制作、槽型水泥板的浇筑方法及渠道衬砌的施工方法。 Traditionally, the use of prefabricated solid concrete slabs for the lining of trapezoidal channels is more common, while the prefabricated slab-type cement slabs have the advantages of light weight, low material consumption, strong water transmission capacity and good anti-seepage effect, therefore, it is recommended Lattice slab lining channels. Taking the canal lining of Shuangqiao farm sewage irrigation area in Beijing as an example, the design of trough type cement board, the production of iron formwork, the pouring method of trough type cement board and the construction method of channel lining are introduced.
