Introduction
Construction processes are diverse and based on different site conditions will be requiring different set of excavation operations in general. Excavation depending on the type of the soil involved invariably will include rock content in the same. The type of the rock, the size of the rock will vary depending on the actual type of the soil being excavated. For instance simple soil excavation need working with removal of soil from the top layers of the ground that can impend the construction process by loosening the soil or weakening the support structure laid for the construction. Rocky excavation is the excavation of the rocks from the rocky surface, which seriously hampers the construction process. During this phase of construction, there will be need for extensive removal of the rock from the surface and the depending on the type of rocks, their sizes and the spread, extensive hammer forces will be needed to apply for removing the same. Earth excavation is the part of the construction process; where in the actual earth contained below the top layers of the soil will be removed to make room for the construction process. Other excavations like the cut and fill type of excavation, trench excavation and Basement excavations involves removal of considerable amount of the soil and rocks from the soil and these constituents will be disposed as feasible. Same is the case with qua
ies, during the excavation of the soil and the ground of the qua
ies, there will be excavation of the soil and rock constituents. In any of these excavation processes, depending on the environment (soil condition, matrix) as well depending on the type of the equipment and the tools employed, there will be invariably availability of the rock and rock pieces s in different sizes and shapes for disposal. In this connection, the ways and means through which these disposal rocks can be reused is the discussion theme of the cu
ent report. Since the rocks and the soil needs are inevitable for the construction process and the procurement of the same for the construction do involve heavy costs in purchases, involves transportation costing as well associated Green house gas emissions, it is necessary to curtail the complications associated with this process by recycling the waste rock from the excavated site. Sustainability in ecology and sustainability in economy is possible though this type of the intervention (Schwartzentruber, & Robert, 2020).
Insights into the Reuse of the excavated rock
The key aspects that define the reuse of the rock and the soil from the excavation site makes up the important aspects that define the reuse. Geographical conditions of the soil or the rock, the technological aspects make up the prominent frameworks for defining the usage of the excavated material. Further the actual soil condition (ex: degree of contamination) etc defines the pre-processing any if required for the material reuse. Nevertheless considering the fact that every year several tonnes of the excavated soil and rock is just being dumped into the landfills without exploring any constructive usage of the same makes an primary aspect of consideration for reuse. However reuse and recycling the excavated rock need to be done to meet the actual construction application needs of the strength, durability, physical and chemical property integrity. Hence a wide consideration to all these factors is needed before using the excavated soil and rock for the required construction usage needs (Sutton et al.,2019).
Reuse of the excavated soil and rock does have implications of the emissions possible due to the construction process that does not include reuse. Reuse of the excavated soil and rock will not only serve the cause of the environmental integrity but will also will solve the problem of u
an resource scarcity. More significantly if the rock and the soil are not available in considerable quantity for the construction usage in the u
an localities, procuring and mobilizing the same to the construction sites will be hectic and local reuse of the excavated soil and rock can be an effective solution to this resources scarcity problem. Rock and soil are natural resources and most of the material excavated is simply subjected to the land filling process. The rock and soil of about 60% in total is land filled every year. Only remaining 40% or part of that will be subjected to any constructive construction application. The same material if is subjected to the reuse in the...
