The flume mould is specially used to produce the steel mould of trapezoidal concrete ditch. It is mainly used in the prefabrication production. Its structure is the form of vertical mould, which is composed of internal mould and external mould. Therefore, the mould needs to be assembled before use. This assembly process is often relatively simple. Only the internal mould and external mould need to be fixed together, and the bolts at the joint should be tightened so that there is no difference between the moulds It's OK to leave a gap. Since trapezoid ditch molds are used for prefabrication production, dozens of prefabrications will be produced at a time. Therefore, in order to prevent slurry leakage after concrete injection, it's optional to use an electric wrench to screw the bolts of the mold, which can save labor and guarantee the production quality.
After the flume mould is evenly brushed with a layer of release agent in the spliced mould, the concrete can be poured. It should be noted that the concrete to be used needs to be proportioned in advance with a concrete mixer according to the specified proportion and mixed evenly. After grouting, it is necessary to mix the concrete slurry at a constant speed with a vibrating rod. This step is very important for the production and manufacture of the prefabricated parts of the trapezoidal ditch. If the vibration is not sufficient, there will be bubbles inside the prefabricated parts, resulting in a layer of dense honeycomb holes on the surface of the prefabricated parts, which greatly affects the appearance, and at the same time, it will lead to the insufficient compressive capacity of the trapezoidal ditch and easy to collapse, After shaking, we can wait for it to solidify completely and remove the trapezoid ditch mold.
Sink mold is also called drain mold. It is a kind of trapezoid or U-shaped mold. The use of intercepting sink mold is basically on the highway, and different regions, different construction schemes, and different production standards of intercepting sink. Whether the final product intercepting sink mold is practical or not, in fact, the quality is the most important. There are many manufacturers producing intercepting sink mold in the market In order to improve the performance of various aspects of the mold, Taihua mold factory innovated the whole field by introducing advanced production technology and equipment from abroad, and obtained substantial reform and innovation
