Ditch mold is widely used, in addition to irrigation and water conservancy, in high-speed rail, highway and other engineering fields of drainage is also used. The internal design of U-groove die is based on the radian of specific R, which determines the difficulty of making the die. Generally, the use of U-groove components will be moved to the construction site after a long period of maintenance. Because of the particularity of the internal structure, the U-groove mold often needs to be bent on the whole steel plate, so as to ensure the smoothness of the precast concrete block, and will not crack or deform due to repeated use.
The specification and label of concrete used in ditch mould shall be strictly in accordance with the design drawings, and the technology used shall meet the requirements of production specifications. Before mixing, the quality of some raw materials shall be checked, and then mixed according to the designed proportion. During mixing, the water content of concrete shall be paid attention to at all times, and the adjustment shall be made in time, Ensure the quality of concrete meets the requirements. After mixing, concrete shall be used within two hours. When vibrating, attention shall be paid to the density of concrete. If important measures to ensure the quality of concrete are taken, and vibration time shall be strictly controlled when using vibration platform, so as to make the concrete in it even and avoid excessive vibration, It's usually between 20 and 30 seconds. After the concrete vibration is completed, the water irrigation ditch mould shall have six hours of watering and curing time. In summer, it should be covered to avoid direct sunlight exposure, so as to ensure the hardness and quality of the water trough. The mould of railway water trough is specially designed for railway drainage, so it is targeted and conforms to the regulations of railway transportation.
