What are headworks?

Any construction at the head or diversion point of a river is referred to as a headworks in civil engineering. It is a smaller version of a barrage that is used to channel water from a river into a canal or from a major canal into a smaller canal. The word "head" here means the beginning, not the height of the structure.

Headworks can be constructed out of earth, rock, concrete, steel, or a combination thereof. They usually consist of two parts: a weir and a dam. The weir is a low wall of rocks or earth that prevents water from flowing past it but allows it to pass under it. The dam is an embankment on which the weir is built. It often has a spillway at its base for excess water to escape. Headworks are used primarily for flood control but also for irrigation, power generation, and recreation. They may be permanent or temporary.

There are three types of headworks: outlet, interlock, and diversion. With outlet heads, the goal is to allow some of the river's flow to go unharmed while also preventing large amounts of water from entering the system. This type of headworks is most commonly found on small canals or ditches that feed into larger waterways like rivers. Interlock heads use two weirs and two dams to prevent any one section of the river from causing a problem downstream.

Why are headworks constructed?

Water intake facilities, also known as headworks, are built to pull water from a river (or reservoir) into the main canal. Water intake facilities are typically developed in conjunction with a dam, sediment tank, river control structures, hydropower plants, and other buildings. They can be located far away from where the water is used because it is easier to transport water over long distances than it is to transport heavy equipment such as dredgers or pumps.

Headworks act as filters by removing large objects such as tree branches and sand from the water flow. This allows smaller items to pass through and be collected by the next section of the canal system. The largest object that can be removed is dependent on the design of the headwork itself. For example, if the headwork is made out of concrete, then it can only remove objects up to a certain size. Objects larger than this will need to be removed by later works on the canal.

Some headworks are designed to produce different types of water for different parts of the canal network. For example, water for irrigation can have lower levels of contamination than water for drinking so some headworks separate the two types of water. Other headworks use physical processes to provide water at various points in time. For example, a weir may be used to create a small lake behind it at the end of each fishing season.

What is a headhouse used for?

A headhouse is a greenhouse expansion or part that acts as the "work center." Headhouses give efficient work space to the greenhouse without compromising precious growing space. These rooms are frequently used for storage, office space, quarantine, and potting. The name comes from the fact that they house the equipment used to brew beer: the head.

The most common type of headhouse is the walk-in closet style unit. These can be freestanding units or built into a wall. They range in size from a small room with just enough space for a person to stand up inside it, to large rooms where people can move about comfortably. Closet headhouses are usually insulated against the outside weather conditions and sometimes even have heating/cooling systems installed within them.

People who live in apartments often have no other choice but to use closet headhouses. These are generally not attractive, so adding window boxes or plants to them goes a long way toward making them more presentable.

Headhouses are useful tools for growing plants in areas where it would be impractical or impossible to set up a full-scale greenhouses. For example, someone living in an apartment building could grow some tomatoes or cucumbers in a headhouse before winter sets in if they didn't want to risk losing their crops due to the cold temperatures outside.

What is a bosshead?

A boss head clamp (or simply bosshead) is a device that holds two rods at a 90-degree angle to each other. It is simply two c-clamps with jaws made up of a holding screw (movable jaw) and a v-shaped seating plate (fixed jaw). The name comes from the fact that the jaws look like the head of a bulldog.

Bossheads are used in many applications where it is necessary to hold two objects together in a rigid position while working on one or both of them. For example, they are used by machinists when repairing parts held in place by set screws. They can also be used as handles for pulling metal sheets into position for welding or some other form of heat treatment.

The bosshead is used instead of more common methods such as clamps or vices because it allows for easy adjustment of the space between the objects being held together. This is particularly useful when trying to make precise cuts without removing the objects being held together from their workpieces.

Bossheads can also be used as a power tool holder. When mounted on a stand or table, they allow several different tools to be used on one project without having to remove the objects being held together from their workpieces.

Finally, bossheads can be used as an improvised weapon.

What is a bosshead used for in science?

A boss head is one of three components that support a Florence flask or conical flask on a retort stand. A boss head is used to keep the clamp in place so that a glass holder does not fall or shatter between the clamps. The boss heads are also called safety pins because they protect the edges of the glass from being scratched or nicked when removing it from the retort stand.

In chemistry, a retort is a long, thin tube or cylinder of metal or plastic into which chemicals are placed to subject them to heat and pressure in order to release any volatile substances present. The word "retort" comes from the Latin word "reter", meaning "backward". This refers to the fact that when chemicals are heated in a retort, they often decompose or change state before becoming volatilized. Thus, products are released from the retorted chemicals in the forward direction, i.e., out the top of the retort. Volatile products leave in vapor form while non-volatile products remain in the sample after heating it in the retort.

Retorts are used in chemical testing procedures where access to laboratory equipment is difficult. They provide a container within which samples can be tested under high temperatures and pressures without contamination from outside sources. This is particularly useful for testing chemicals that would damage other instruments if handled improperly.

What is a work of the head?

A work-holding head (as on a lath). Also a metal block with holes for holding tools.

Workheads are used in metalworking shops to hold metal while it is shaped or molded. The worker uses a hand tool, such as a hacksaw, to cut pieces from the metal blank. After each piece is cut, it is placed on one of the workheads for further shaping or molding. When the job is finished, the worker takes the workhead to another part of the shop and removes the pieces, which are then cleaned up and filed to perfect their shape.

The word "workhead" comes from the fact that they resemble the heads used by taxidermists to hold animal specimens while they are worked on.

They are used instead of clamps because they can be applied evenly pressure across the entire area of contact, rather than only at specific points, like clamps would do. This makes workheads useful for shaping large objects, such as table legs, rather than just small parts, such as screws. Workheads come in various sizes and shapes. The most common are flat and round but others include octagonal, cruciform, and even teardrop-shaped heads.
