Reiki level: its varieties and scope

Rake leveling is an additional tool that allows you to perform geodetic work in construction, as well as used in geological or topographical studies. With it, the differences in elevation are recorded. The leveling rail is a rectangular plane with a scale placed on it, which is marked with a certain price of division.

Varieties

There are four types of this device:

• Rack made of wood with the possibility of unfolding;
• Telescopic;
• Fiberglass rake;
• High-precision invar.

Description

Modern products can be produced for digital and conventional levels. Digital racks are used for levels that can read BAR-codes that are applied to the surface of this device. With the help of such devices, the distance to the device and the difference in height are determined. Also, these devices have on the reverse side of the usual graduation, as a result of which they can be used as simple levels.

• Rake leveling, made of wood, folds in the center. The length of each section is about 1.5 meters. Wooden slats are heavier than telescopic slats . But they have a more reliable folding mechanism in comparison with the specified analog, which has a play in the mechanism fixing button. Such rake leveling is a dielectric. This is important when working near open wires and high-voltage power lines.
• Rake leveling telescopic in the modern version is made of light materials, such as plastic or aluminum, which is very convenient to use due to low weight. They have a round level, which makes it possible to put this device strictly vertically. Reams with lengths of 3, 4 and 5 m are often used. When folded, they have a length of not more than 1.5 meters. The scale for such products is applied on both sides (one is placed millimeter - for close work, and on the other - in the form of checkers for use at long distances).
• The fiberglass rail is used in working with a digital level. Like all the above devices, it has two-way markings. On the one hand, as a normal level, on the other - a metric scale. Such a rack is made of a dielectric material called fiberglass. Therefore, it can be used near high-voltage electric lines.
• Invarious slats are used to perform high-precision survey of terrain. Here, the accuracy of determining marks is not more than one millimeter. Its body is made of wood and covered with invar ribbon. These racks make a length of 3 m. Due to the ease of use and light weight, they are in great demand.

The result

Now you know what a leveling rake can be. How to use it, known topographers, cartographers, builders, miners. However, everyone can learn this skill. Sometimes another name for this device is used - construction rake, or geodesic. The price for such a product depends on its size and accuracy of divisions.
