Purpose
Levelling the surface for the construction of a reliable building and calculating the depth of the foundation. These and other processes cannot be completed without such an important device as an optical level. This is a geodetic device with a simple design that allows you to carry out work with perfect accuracy. Correct calculations at the beginning of construction are not only cost saving, but also they ensure the safety of the combined structure.
Front of work of the device
The optical level is designed to work on a construction site of any size and length. With it, the elevation marks of points on the surface are determined relative to a specific base level. During construction, such processes must be carried out quite often, which experienced builders know. The level helps to make the surface even, suggests where to remove earth, and where, on the contrary, to add. The level will become an indispensable assistant in determining the depth of the trench for the foundation, and will also be useful for creating a screed or pouring a concrete floor. Optical levels are especially helpful if the work front has a huge area.
How the level works
An optical level is a telescope on a stand with lifting screws that change the tilt of the tube in order to calculate the ideal horizontal position. The stand also has a built-in bubble level, which the builder uses as a guide.
To level the surface using an optical level, you will need a dimensional grid with cells – the survey will be carried out in the grid nodes. The device is best placed in the center of the object on which the work is being carried out. Then the leveling is performed and the focus of the tube is adjusted.
Errors when working with a level
Often, builders who do not have experience working with the device believe that points with a higher elevation mark are located higher than those with a lower one. In fact, the situation is completely opposite – a large value of the rail means that it is in a depression. The most important thing when starting to work with a level is to list and double-check the measurements obtained. Then your work will be perfectly level. It should also be taken into account that you will need two pairs of hands to work with an optical level.
What to look for when buying a device
To work with this device, you will need a tripod and a measuring rod. Our online store allows you to buy an optical level and all the necessary components for it. You can get more detailed information about the products using our catalog, and customers can also call our employees who will advise on any product.
