Problems solved by technology

[0002] During the construction of water conservancy projects, underground pre-buried pipelines are usually used to realize the centralized discharge of urban wastewater, but the pre-buried pipelines are deep and the maintenance costs are high, especially the main transportation pipeline, which is long in length and has many nodes. , difficult to locate
[0003] In the drainage process, due to the weather, there is a difference between the flood season and the non-flood season in the pipeline drainage. In the rainstorm weather, the water volume suddenly increases, the water flow in the pipeline increases, the impact force of the water flow and the mixture in the water increase. During transportation, due to the impact of the water flow and the inertia of the mixed sediment and stones in the water, it is very easy to cause extrusion on the inner wall of the pipeline, thereby reducing the practical life of the pipeline, and the water volume increases. The transportation of a single pipeline cannot meet the needs of excretion, which is easy cause waterlogging
[0004] To this end, a water conservancy construction diversion and drainage structure and its construction method are provided to solve the problem of switching pipelines between flood seasons and non-flood seasons and protecting the main transportation pipelines

Abstract

The invention relates to the technical field of hydraulic engineering drainage construction, in particular to a hydraulic engineering construction diversion drainage structure and a construction method thereof. The hydraulic engineering construction diversion drainage structure comprises a feeding pipe and a discharging pipe; the feeding pipe and the discharging pipe are installed at the lower endof a foundation in a pre-buried mode; deep holes which are vertically distributed are formed between the feeding pipe and the discharging pipe; and flow dividing pipes are symmetrically arranged on the left side and the right side of the feeding pipe and the left side and the right side of the discharging pipe. The construction method of the hydraulic engineering construction division drainage structure comprises the following steps of S1, base pouring; S2, fixed block pouring; S3, lifting block pouring; and S4, lifting block adjusting. The structure and the method have the beneficial effectsthat by arranging a lifting block with a spiral upper and lower flow channels, high-speed impact water flow is buffered, the impact force of the water flow is reduced, meanwhile, the purpose of left-right flow division is achieved through up-down circulating flow of the water flow, damage to a main pipeline is avoided, and the service life of the main pipeline is prolonged.
