Description

Pipeline for hydraulic engineering convenient to concatenation

Technical Field

The invention relates to the field of hydraulic engineering, in particular to a conveying pipeline convenient to splice for hydraulic engineering.

Background

Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harmful substances and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims.

The object can be divided into: flood control engineering for preventing flood disasters; the irrigation and water conservancy project, also called irrigation and drainage project, which can prevent drought, waterlogging and waterlogging from serving the agricultural production; channel and port projects that improve and create shipping conditions; urban water supply and drainage works serving industrial and domestic water, and treating and draining sewage and rainwater; water and soil conservation engineering and environmental hydraulic engineering for preventing water and soil loss and water pollution and maintaining ecological balance; the fishery water conservancy project of fishery production is protected and enhanced; sea reclamation engineering and the like meeting the needs of industrial and agricultural production or transportation. One hydraulic engineering serves multiple targets such as flood control, irrigation, power generation, shipping and the like at the same time, and is called comprehensive utilization hydraulic engineering. The water storage engineering refers to a reservoir and a small reservoir (excluding an adjusting reservoir specially constructed for water diversion and water lifting engineering), and statistics is respectively carried out according to the large reservoir, the medium reservoir, the small reservoir and the small reservoir. The diversion project refers to the project of automatically diversion from surface water bodies such as river channels, lakes and the like (excluding the project of diversion from water storage and water lifting projects), and statistics is respectively carried out according to large, medium and small scales. The water lifting project refers to a project for lifting water from surface water bodies such as rivers, lakes and the like by using a water lifting pump station (excluding a project for lifting water from water storage projects and water diversion projects), and statistics is respectively carried out according to large, medium and small scales. The water transfer engineering refers to cross-basin water transfer engineering between water resource first-level areas or independent basins, and the storage, guide and lifting engineering does not include supporting engineering of the water transfer engineering. The underground water source engineering refers to a water well engineering utilizing underground water, and statistics is respectively carried out according to shallow underground water and deep confined water.

In water conservancy construction, many pipelines often need to be laid, and because the free length of pipeline has some restrictions, so in order to lay out long distance pipeline, just need splice the pipeline, traditional hydraulic engineering pipeline concatenation operation is comparatively loaded down with trivial details, and generally all fix through flange joint's mode, long-time exposure leads to the screw corrosion easily in external environment, thereby inconvenient dismouting, simultaneously also can appear the condition of leaking because the screw is not hard up and take place, lead to hydraulic engineering construction speed slower, therefore, in order to solve this type of problem, we have proposed a pipeline for the hydraulic engineering convenient to splice.
