After the onset of mechanical excavation, the associated risks arise from damage to the machinery and excavation tools. The equipment can be damaged by variations in soil pressure and corrosion to mechanical parts of excavators, and so on.
A set of mechanical excavation equipment should be made according to industry standards, which includes vibration reduction techniques and the provision of higher load capacities to reduce the vibrations.
Typically, mechanical equipment is built using high-pressure liners or hydraulic casings, which can deform and increase the amount of vibration in a machine. In order to combat vibrations, the hydraulic parts of the equipment may need to be made more resistant to high pressure or to be mounted and maintained on metal-over-carbon bearings.
A mechanical excavation equipment is always subjected to rough terrain conditions, especially on steep slopes or slopes of uneven and uneven surfaces. Sometimes the wheels will roll on and off of flat spots on the surface, exposing the excavator to damage due to loosening of bearings, wheels, and rims.
The soil or material can cause any mechanical equipment to vibrate more and, therefore, result in costly repair or replacement. Equipment can be damaged by the impact or collision of the heavy soil with a blade on the excavator.
In terms of reliability and durability, mechanical excavators are very reliable, considering the presence of hydraulic parts of the machinery. An excavator may roll off a steep slope due to one of the following reasons:
The suspension may be not fully lifted due to load imbalance on the machine.
The hydraulic power pack and equipment may be damaged by rotary machinery or soils which can cause the excavator to roll off the same incline.
The vibration of the equipment due to soil pressure and environmental elements can cause a wheel to turn off the axle. The problem can be solved by the provision of extra hydraulic components.
Kinetic Hydro Excavation
Kinetic hydro excavation has many applications and is a great alternative to mechanical excavation in that it limits many of the risks associated with mechanical excavation. The technique involves laying a pipe underground. Water is pumped in, boring as much as 20cm into the ground. The pipe is bored vertically or horizontally. The pipe is then brought down to the same depth, and holes are dug through the earth that are the same length as the pipe. The pipe is then lowered into the hole. When the pipe has reached the desired depth, water is added. The gas will flow through the pipe until it reaches a higher elevation, and then it will be allowed to run for a long time (several weeks or months). The force of the gas coming through the pipe may cause the pipe to open or leak, but this happens with any hydrodynamic equipment. Water coming through a hole in the ground could rot the soil around it, but if water is added at the same time, the soil is protected, because the soil is wet and has a chance to dry out. When the process is complete, the hole that was dug out has been filled back in, and the soil surrounding it will be nice and dry, even though the hole was still dug out. This technique will leave behind a two-meter diameter hole in the ground. Kinetic hydro excavation is very good for repairing worn out pipelines, excavating for utility cables or installing plumbing, as well as other applications. Kinetic hydro excavating requires a lot of skilled work to fill holes and other excavations with water. It is very good to do this type of excavation in the winter months, and in a quiet area. The process needs to be done slowly and carefully.
