Description

technical field

[0001] The invention relates to the field of inverted siphon engineering, in particular to a trolley three-stage pouring working method. Background technique

[0002] With the advancement of science and technology, the problem of uneven distribution of water sources has become prominent. For arid areas, it is particularly important to build long-distance canals or waterways to dispatch water from areas with abundant water sources to water diversions and downstream along the way. When the channel encounters a road or a river ditch that crosses the plane, it is usually solved by the inverted siphon technology, so that the water passes under the road or the ditch. The inverted siphon project has the advantages of convenient construction and low cost. Inverted siphon technology has been used in many places in my country, and inverted siphon projects have been arranged to transmit water resources through inverted siphon tunnels in straight and inclined sections. ...
