It is mainly used to form and trim water channels to ensure the smoothness and stability of water channels. Water channel forming machines can be used for various types of water channels, including irrigation channels, drainage channels, ditches, etc. Its main function is to press and trim the soil during the construction of the water channel, so that the bottom and both sides of the water channel present a certain slope and flatness, so as to facilitate the smooth flow of water and the stability of water flow. It mainly uses the weight and vibration force of the machine to press and trim the soil. The main components of the water channel forming machine include engine, steering system, hydraulic system, vibration system, working parts, etc. Among them, the vibration system is the core component of the water channel forming machine, which compacts the soil through vibration force and trims the soil. The water channel forming machine can be adjusted as needed to achieve different degrees of vibration and pressing.

[0003] After the channel concrete is cast, it is necessary to cut a crack in the concrete at intervals and fill it with asphalt to prevent the concrete from expanding and contracting due to temperature.
