[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing, also known as ordinary concrete, is widely used in civil engineering.

[0003] A trough is required during concrete construction, but the existing concrete construction trough cannot adjust the inclination and cannot be applied to construction blind spots of different sizes, which brings great inconvenience to users and reduces the practicality of the existing concrete construction trough.

[0004] For this purpose, we propose a concrete construction trough. Utility Model Content
