Background technique

As an important way to save water in engineering, channel lining has attracted much attention at home and abroad. China's water diversion (transmission) channels have many engineering points and long engineering lines. According to the latest data, the length of irrigation channels with a flow rate greater than 0.2m ³ /s in China is about 1.1 million km, of which the length of the lined channels is about 300,000 km. The channel lining rate is less than 30%, especially for small and medium-sized channels. Channel mechanized lining technology has attracted the attention of engineers and technicians due to its high construction efficiency. However, the application of lining machines in my country is still in its infancy. The lining machines that have been put into use include pneumatic slit V-shaped channel concrete lining machines, PMCQ650 concrete lining machines and other models. automation, but there are many drawbacks. For example, some channel lining machines can only line the half-section of the channel, so that the concrete lining of the channel needs at least three operations to complete, that is, pouring the two side slopes separately, and then pouring the concrete at the bottom of the channel; although some equipment can complete the channel at one time Full-section concrete lining, but its structure is complicated, maintenance is troublesome, heavy, and expensive; some equipment is simple, mechanization and work efficiency are low, construction is divided, and there are many follow-up work. In addition, in the past, channel lining machines mostly relied on wire rope traction and track walking, and channel concrete molding mostly relied on plate vibration and manual vibration. The machine itself has no plastering device and needs manual plastering, and the degree of mechanization is not high.
