U型排水槽模具在路面使用的比较多，减少路面积水，排水槽模具在生产中，将预先做好的配筋放入模具中定位，然后注入调配好的混凝土，然后通过振动棒进行搅动，充分的将混凝土中的气泡导出，然后放置晾干在进行脱模，排水槽模具就制作成型了，一些较大规格的还会需要焊接的方式生产。U型排水槽模具具有线性好,表面光滑,整体性强,对城市的贡献极大,以达到生产出不同模具的目的。因为其造价相对不是很高,同时样式新颖,美观大方,不变形,易脱模。U型排水槽模具,矩形排水槽模具特点主要是在于模具外形上，在制作工艺以及技术上没有区分，U型构造稍微贵一些，因为比较费工费事。在U型排水槽模具,矩形排水槽模具特点上，还要考虑梯形的排水槽，因为很多工程现在改进了模板的需要，采用的是拼接式的排水槽，单块拼在一起为一整套排水槽预制块。一般这种模具数量使用数量不是很多，开塑料模具的成本较高，尺寸多样，用于高速公路和高速铁路电缆槽和电缆沟的预制，采用钢模具生产，特点速度快成本低，在生产过程中要注重细节,生产出的模具要求也严格。

U-shaped drain groove die is used more on the road surface to reduce water accumulation on the road surface. In the production of drain groove die, the pre-made reinforcement is positioned in the die, and then the concrete is injected. Then, the air bubbles in the concrete are fully stirred by the vibrating rod, and then the air-drying is placed for demoulding. The drain groove die is manufactured and moulded, and some larger rules are formed. The lattice will also need to be manufactured by welding. The U-shaped drainage groove mould has good linearity, smooth surface, strong integrity, and great contribution to the city, in order to achieve the purpose of producing different moulds. Because its cost is relatively not very high, at the same time, the style is novel, beautiful and generous, not deformed, easy to demould. U-shaped drain groove die and rectangular drain groove die are mainly characterized by the shape of the die, there is no distinction in manufacturing technology and technology, U-shaped structure is slightly more expensive, because it is more labor-intensive. In the U-shaped drain groove die and rectangular drain groove die, trapezoidal drain groove should also be considered, because many projects now improve the need for the template, the use of spliced drain groove, single piece together into a set of drain groove prefabricated blocks. Generally, the number of this kind of mould is not very large, the cost of opening plastic mould is high and the size is diverse. It is used for the prefabrication of cable trough and cable trench of Expressway and high-speed railway. It is produced by steel mould, which has the characteristics of high speed and low cost. In the process of production, attention should be paid to details, and the requirements of the mould produced are also strict.
