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. ...

AI Technical Summary

Problems solved by technology

[0005] 2. The needle-beam trolley in the prior art is equipped with a pressure relief structure for the excessive expansion in the concrete pouring process. However, only the pressure relief is considered, and the discharge after the pressure relief is not considered, which often leads to the random discharge of the pollution trolley

[0006] 3. The needle-beam type trolley in the prior art, the pouring nozzles all spray concrete directly, without considering the flow direction of the concrete after spraying, and cannot accurately control the flow direction of the concrete

[0007] 4. The needle beam trolley of the prior art has a valve to control the pouring during the pouring process. However, the pouring material often remains on the valve, which will soon pollute the valve plate and affect the further use of the valve plate.

[0008] 5. The needle beam trolley in the prior art has a small pouring nozzle, and it is difficult to process or realize more functions

[0009] 6. The pouring valve of the prior art causes sewage to flow sideways during cleaning, and it is difficult to have a good cleaning method to collect sewage

[0010] 7. When the trolley of the prior art pours the lining, the pouring is extensive, and it is difficult to achieve precise control of the pouring volume, resulting in various problems such as waste, pollution, mold expansion, etc.
