The two main types of spindle used to raise the gate in a sluice valve are the Raising Spindle type valve and the Non-Raising spindle type valve. These types differ in how the spindle is connected to the gate and how the gate is raised during operation. …
Sluices are important civil engineering structures to cope with water level differences and to ease shipping. Since the first sluice was built in China along the Grand canal several types of …

In the hydraulic structures of hydropower station and water conservancy project, sluice is one of the most important parts, which undertakes the tasks of flood control, sand flushing and water inflow.
Details about the types of sluices and their uses are provided separately. Sometimes the non overflow blocks of a concrete gravity dams are used to accommodate the penstocks (large diameter pipes) which carry water from …
Type B – sloping masonry apron. Type C – rock sloping apron. TYPE A: In this type, the water is made to fall vertically on to a horizontal apron. Further, it may be divided as type A and type A1. In type A, surface of downstreamapron is at or below the low water level. In type A1, the downstream is partially orwholly above low water level.

Scouring sluices are holes at the bottom of a or barrage that allow the sand to flow through them. Movable gates are used to cover these openings. When these gates are closed, silt builds up. When enough silt has built up, the gates are opened, and the silt flows through scouring sluices toward downstream. 4. Fish Ladder. Fig 5: Fish ladder
The west coast of Great Britain has the potential for barrages to create tidal range reservoirs that both facilitate electricity generation and prevent flooding from sea level rise. Seawater flows into and out of the reservoir, or …
For fine gold recovery the use of riffles can actually be a negative design element and most boxes specifically built for this type of gold don't use any type of riffle system. ... sluice box that maximizes the good features of both types of sluices while minimizing the negative aspects found in most dual-mode sluice designs. Specifically we ...

The spillway can be used to provide flood-control regulation for floods either in combination with flood-control sluices or outlet works, or in some cases, as the only flood-control facility. A powerhouse should not be …
Pool type and steep channel types are common type of fish ladder. Fish can take rest in holes staggered in oblique walls. Canal Head Regulator . It is provided at head of off taking canal. Functions. It regulates the supply of water entering the canal; Controls the entry of silt in canal. It prevents the river flood from entering the canal.

2.1 Sluices may be classified depending upon their purpose, their hydraulic operation or their alignment. The first two types have been described in 0.2 and 0.3. Based …
Regular maintenance of wire rope is considered the key to ensuring the safe operation of a sluice gate. Along these lines, in this work, a six-wheeled wire rope climbing robot was proposed, which can carry cleaning and maintenance tools for online cleaning and safety inspection of the sluice wire rope, without its disassembly. The developed climbing robot is …
Some of the types of siphon spillways are as follows:-Tilted out type of siphon spillway. This type of dam spillway is provided when the valley is too narrow to accommodate a separate spillway. In this case, a siphon pipe can be installed within the dam body. The siphon pipe is connected to an air vent.

This study facilitates the application and analysis of the studied models for the design or calibration of sluice gates and where the flow in open channels needs to be controlled or measured using ...
Gates are important water management structures. One common example, the sluice gate, has been used for many years [1]. The gates themselves have different types, each having advantages and disadvantages, and a gate type can be selected according to the specific application and its functional characteristics.
