Land Surveying Equipment That Are Essential for Surveys
Land surveys are fundamental for the design and construction of particular aspects like roads, buildings, etc. Land surveys are done to mark boundaries, map the topography of land, create elevations for buildings to ward off floods, to ascertain that buildings have been constructed as per particular recommendations, to map river bottoms for dredging, layout photo control for aerial photography, map the layout of tunnels, airports, and so much more.
Land surveys should be carried out with keen details to ensure that the best results are achieved. Surveyors should, thus, make use of certain equipment which may include:
GPS equipment- It uses satellites to conduct surveys by taking the variations in height between two points along with the distance and directions.
Tripod equipment- They are used to hold surveying equipment like theodolites, total stations, levels, and transit. They should be unwavering while in use because a slight change in position requires the repeat of a survey. Its accuracy is affected by water, thus the material used to make it should be chosen wisely.
Measurement equipment- The most regular measuring item used is a wheel. The wheel is rolled along the desired measurement and its revolution counted by an odometer which is usually attached to it.
Theodolites- They are used for horizontal and vertical angling, and they can also determine elevation and height.
Laser levels- They produce beams of light that are used to test elevation. They are used for diverse tasks that are essential during construction. They can be manually operated or independent. Self-level lasers do not require being adjusted to determine levels, while manual lasers must be operated by a person.
Laser receivers- They are used with laser levels to cover a much wider area that needs to be surveyed. They pick up the beams of light from the laser levels and make a sound once the right level has been achieved. They are helpful to make the use of laser levels outside and on very sunny days easier.
Single or dual grade lasers- They are utilized when slopes require being assessed. Single grade lasers are used to acquire the gradient of one plane, while dual grade lasers work on two planes simultaneously.
Rotating and straight line lasers- Rotating lasers produce a beam of laser light from a beacon that rotates to assess a plane across 360 degrees, while straight line lasers are used to produce a cross or plumb line.
Pipe lasers- This kind of lasers are very effective when new pipes, drains, or sewers are due for installation. Pipe lasers are used to align pipes and grade them in line with each other, one after the other.
