Description

River course desilting equipment is used in hydraulic engineering construction

Technical Field

The invention relates to the technical field of hydraulic engineering, in particular to river channel dredging equipment for hydraulic engineering construction.

Background

Hydraulic engineering is a general term for various engineering constructions constructed for controlling, utilizing and protecting surface and underground water resources and environments, and is used for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harm and benefiting, and is also called 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.

The engineering is built for eliminating water damage and developing and utilizing water resource. The service objects are divided into flood control engineering, farmland hydraulic engineering, hydroelectric power engineering, channel and harbor engineering, water supply and drainage engineering, environmental hydraulic engineering, coastal reclamation engineering and the like. The hydraulic engineering which can serve multiple targets such as flood control, water supply, irrigation, power generation and the like at the same time is called comprehensive utilization hydraulic engineering. 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.

Whether the water damage is treated or the water conservancy is developed, the water damage is treated through a certain number of hydraulic buildings. Hydraulic buildings are generally divided into three categories according to their functions: a water retaining building; a water outlet structure; special hydraulic buildings. An aggregate consisting of a plurality of hydraulic buildings is called a hydro-junction.

A water retaining structure is a structure that blocks or restricts water flow, has a high height, or adjusts an upstream water level, and is generally called a dam across a river, and is called a dike built on both sides of the river along the direction of water flow.

A water discharge structure is a structure capable of discharging surplus or required water from a reservoir safely and reliably. The concrete dam has stronger anti-scouring capability, and can discharge flood by using the overflow of the dam body, so the concrete dam is called an overflow dam.

In addition to the above two common general buildings, the buildings designed for a specific purpose or for a specific task are special hydraulic structures such as channels, water transportation tunnels, aqueducts or inverted siphons, and the dam blocks the original passages of ships, wooden rafts, bamboo rafts and fish swimming, so that the ship lock, raft and fish way for passing ships, rafts and fish need to be specially constructed.

In the process of carrying out hydraulic engineering construction on some river channels, due to the influence of geographical forms or surrounding environments and construction problems, the problems of sludge accumulation and the like of some river channels can occur, the water flow passing and the water flow velocity of the river channels are influenced, and therefore the river channels need to be desilted; but current river course desilting adopts artifical desilting more or uses the desilting pump to draw silt, and artifical desilting is wasted time and energy, and the desilting pump can inhale more water when extracting the silt of river course bottom, and subsequent silt of being not convenient for is handled.
