[0001] This invention relates to the technical field of molds, and in particular to the technical field of trapezoidal water channel casting molds. [Background Technology]

[0002] Trapezoidal ditches are a common type of drainage system. To prevent them from collapsing and to improve water retention, they are sometimes constructed using concrete. However, existing trapezoidal ditch casting molds are complex in structure and cumbersome to use, and they are also prone to deformation during the casting process, ultimately leading to deformation of the ditch.

[0024] Working process of this invention:

[0025] In the process of using the trapezoidal water ditch casting mold of the present invention, the steel reinforcement support of the trapezoidal water ditch is installed in the pre-dug trench. The bottom of the trapezoidal water ditch can be cast first, and then the casting mold can be assembled and other parts can be cast. Alternatively, the water ditch can be cast in one go after the mold is assembled. When using the one-time casting method, the structure of Embodiment 1 is preferred.
