In construction and engineering too, different types of excavation is done, based on a specific purpose or the material being excavated.
Channel excavation comprises removing materials from drainage ditches and channels, usually to alter water flow or to increase capacity. This helps in alleviate flooding or preventing sediment buildup and stagnation.
Drainage relates to removing water from trenches, ditches, agricultural sites, storm drains, runoff drainage, and also from any structure relating to such drainage. Ditches are excavated for funneling water away from habitable, infrastructural, and agricultural areas to prevent harm from water stagnation.
This type of excavation involves removing materials to clear the way for construction. Gravel or soil are removed from a sandbox or borrow pit for use in another site for fill, grading, or mixing with concrete.
Excavation of huge deposits of sediment in waterways to make them passable is called dredging. It takes place underwater, mostly in river mouths or shallow passages of oceans to enhance navigation for boat traffic.
This is another material-based excavation procedure. Muck, which is an undesirable combination of dirty soil and water and which is likely to contaminate the soil is removed completely to make an area habitable, safe, and passable. The process involves either removing the unwanted muck elsewhere or spreading it out in order to allow the soil to dry.
Foundations structures that support bridges, buildings, and other heavy structures are called footings. They spread the load to prevent such heavy structures from sinking or collapsing. Footing excavation is done after the structural site is properly graded first. This procedure requires high precision as the concrete for the footings are poured first and left to set thereafter.
Roadway excavation is done to remove the excavated materials to another site to make way for new road construction. These materials may, however, also find use as building materials for the new roadway or for building embankments. In certain cases, unwanted slope materials are removed with excavated materials from other sites replacing them.
The excavating here is done underground and involves specialized tools, techniques, and equipment. Diagonal or vertical shafts and horizontal tunnels are dug to build roadways, canals, sewage systems, and subways.
The classification of excavation is also done according to the work’s purpose and includes cut and fill excavation, trench excavation, and basement excavation.
Backfilling is the process of putting soil back into a trench or foundation once excavation and the related work has been completed. The backfill process requires skills and heavy equipment as well as knowledge of the specifications, contract requirements, and soil conditions. Every area soil has unique characteristics, requiring different construction techniques to ensure optimum performance.
In addition, backfill crews take care to prevent impact loading of any pipeline, shaft, structure, cabling, or other buried elements when placing and compacting backfill. There are a few common methods of backfilling and compacting backfill. Filling and compacting trenches for utility lines involves special considerations.
Grading and Compaction
strives to deliver excellence in grading. For this purpose, we have developed several custom buckets and grading tools that work in conjunction with our equipment. We can give you flat or contour grades to meet your requirements. We excel at compaction for utility trenches, ABC underpinning or other dirt work.
With a complete fleet of equipment, we can handle earth moving, slope cutting, compaction, structural excavation or soil stabilization for any job. Roché Excavating is committed to providing the right equipment and staffing required to complete your job. We uses the latest technology available, including GPS, machine and tripod mounted lasers, and years of knowledge and experience. We’ll get your job done right the first time. And we’re able to do all import and export with our own equpiment. This ensures that your job is not subcontracted out to another company.
