Types of Land Surveying equipment That You Require
Land surveying is critical for the design and construction of various aspects like roads, buildings, and so on. 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 is used to take variations in height between two points, their distance and directions by contacting the satellite.
Tripod equipment- They are used to hold surveying equipment like theodolites, total stations, levels, and transit. Tripod equipment must be firm when being utilized to get accurate results, thus, when they are moved they require being reset to conduct a fresh survey. Its accuracy is affected by water, thus the material used to make it should be chosen wisely.
Measurement equipment- The most common of them all is the measuring 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 to determine horizontal and vertical angles, elevation and height.
Laser levels- They give off beams of laser light that is used to determine elevation. They are used for diverse tasks that are essential during construction. They are either self-level or manual. Self-level lasers are able to find their own level without being adjusted at all, while manual lasers require being adjusted.
Laser receivers- They are combined with laser levels to cover wider areas during land surveys. The laser receivers detect beams of light from the laser levels and adjust respectively until the desired level is achieved then make a sound. They are helpful to make the use of laser levels outside and on very sunny days easier.
Single or dual grade lasers- They are used to measure and define the gradient of a slope. The single grade laser only calculates gradient for one particular plane, while dual grade lasers can calculate the gradient of two planes at once.
Rotating and straight line lasers- Rotating lasers give off beams of laser light from a beacon that evaluate an area across 360 degrees, while straight line lasers are used to generate crosses or plumb lines.
Pipe lasers- They are used during the installation of new pipes, drains or sewers. When a pipe is placed in a trench, they are used to determine the accurate placement of the rest of the pipes on the same line and gradient.
