摘   要：结合箱涵卧式模具的结构特点以及预制混凝土箱涵产品的成型工艺，针对现有的定型箱涵模具，设计了一种可调节的、模块化的组合式预制混凝土箱涵模具；通过分析现有模具的结构特点与功能，在现有模具的基础上设计了各部件的可调节模块。该可调节模具具有制作精度高、操作简单、生产效率高等优点，通过安装可调节模块实现了卧式箱涵模具的一模多用，从而减少了构件厂的设备投资，满足了目前预制混凝土箱涵产品规格多样化的需求。

Abstract：Based on the structural characteristics of horizontal culvert box mould and the shaping technics of pre-fabricated concrete box culvert products and combined with the existing shaped box culvert mould, the adjustable and modularized composite prefabricated concrete box culvert mould is designed. By analyzing the structural characteristics and functions of the existing mould, the adjustable mould of each component is designed based on the current mould. The adjustable mould has the advantages such as high precision of manufacturing, simple operation, and high production efficiency, the plurality of functions of one horizontal box culvert mould are achieved through adjustable module, the equipment investment of the component factory is reduced, and the demand of the diverse product specification of the prefabricated concrete box culvert is satisfied.
