The introduction of U-shaped canal moulds is one of the most outstanding moulds. The development of U-shaped canal moulds can not be separated from the construction of many water conservancy projects, and every water conservancy project can not be carried out without U-shaped canal prefabricated blocks, especially in Xinjiang, Qinghai and other places. The usage of U-shaped canal moulds is different in many places. In Xinjiang, the use of U-shaped canal moulds is basically small prefabricated blocks. The length of the moulds is basically half a meter long, and there are small edges on both sides of the moulds. The depth and width of the moulds are basically not more than 80 cm. This is the U-needed steel moulds used in Xinjiang. In Heilongjia, Jilin and other areas, the U-shaped channel steel die is basically rectangular outside, U-shaped inside mode, so according to the use of different areas, the shape is different.
U-shaped channel die is designed to meet the needs of channel construction. Usually, there are many shapes and specifications for the layout of channel die prototype, such as U-shaped channel, trapezoidal channel, rectangular channel, etc. Different shapes correspond to different specifications. The production of large-scale U-shaped canal mold drawings is needed in the construction of water conservancy projects at present. In order to ensure the quality of formwork, it is usually necessary to verify the designed large-scale drawings before mass production. According to the processing content and method of U-shaped canal mould, because according to the different design drawings of construction units, the U-shaped flume shows a variety of structures, but the length is mostly 1 meter long, while the inner depth and upper mouth width are different.
