As effective as our products are, choosing the correct equipment for your project might be a challenge. However, our experts on ground engineering can help you to decide on the best equipment for your project.
Today, the social and industrial growth has increased the importance of ground engineering. In fact, the profession plays a crucial role in projects such as power stations or the expansion of infrastructure systems like harbors and airports. Therefore, it is good to consult to an expert before deciding on the method of ground improvement.
METHODS
Deep vibro compaction and vibro replacement methods are mainly to increase the strength of granular soils as well as unfavorable soil conditions. They are also beneficial for the improvement of deformation characteristics of the same type of soil. The two methods work by enhancing the bearing capacity of the weak layer. Then, they utilize the benefit of the improved resistance. Ergo, this results in a transition between deep foundation and soil stabilization. This way, the transition ensures a structural support below or on the improved ground surface both safety and economy wise.
As OMS team, we support our customers by recommending the best soil improvement equipment solutions. Vibro compaction and vibro replacement (stone columns) as well as vertical drain (wick drain) equipment of OMS have proved themselves in the global market from Europe to Middle East, South East Asia and America continent.
VIBRO COMPACTION – TOP FEED GROUND IMPROVEMENT TECHNIQUE
Vibro compaction method is mostly suitable for fine granular soils with seismic risk. For this reason, experts suggest for land reclamation projects to decrease the risk of liquefaction. Furthermore, the technique is useful for the densification of sand-like soils on site through an OMS Vibroflotation prob. Due to the concurrent impact of saturation and vibration, loose sand particles changes into a more compact state. As a result, lateral confining pressure of the sand mass rises.
Vibro compaction top feed technique is convenient for medium to coarse-grained sand with silt content. Cohesive soils with silt and clay does not respond to vibratory compaction.
Vibro Compaction
Tandem Free Hanging Ground Improvement:
The tandem vibro compaction includes two vibroflotation probes. Each prob suspends from the same crane. Land reclamation projects that require 20 – 25 m depth uses this configuration. The quality of compaction/stone column is controllable with a data logger supplied by OMS. Thence, the depth, compaction rate, time-related compaction and withdrawals can be measured and monitored. The data logger is also able to measure the gravel volume.

Vibro replacement stone columns are a ground improvement technique to improve the load bearing capacity and reduce the settlement of the soil. On many occasions, it is noted that the local soil is, by nature, unable to bear the proposed structure, so the use of ground improvement techniques may be necessary. Use of stone columns is one such technique. The stone column consists of crushed coarse aggregates of various sizes. The ratio in which the stones of different sizes will be mixed is decided by design criteria

Ground Improvement by Vibro Stone ColumnsDesh Sonyok
Vibro replacement stone column is one of the widely used soil improvement technique to improve the settlement characteristics, bearing capacity and mitigate the liquefaction issues of the soft soil. In this paper, improvement of the settlement characteristics of the soft soil is considered for the analysis based on the available case histories. A settlement estimation method proposed by Preibe (1995) is verified quantitatively. Finally, an analytical solution for settlement of soft ground for the stone column design is proposed. The proposed method of calculating settlement is based on the basic concept of composite material and soil mechanics. However, the result of this preliminary work is yet to validate numerically and in the field. Detailed research in future is necessary to check its validity and applicability

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2. INTRODUCTION Transportation contributes to the economic,industrial,social and cultural development of any country. Transportationby road or highways is the only mode which could give maximum service to one and all. When the soil on a project site cannot support the loads, ground improvement to increase strength, reduce compressibility, and enhance performance under applied loadings may be required. The field of ground improvement techniques has been recognized as an important and rapidly expanding one. Various methods are discussed below:
4. VERTICAL DRAINS These consist of a column of pervious material placed in cylindrical vertical holes at sufficiently close spaces. All drains should be connected at the ground surface to a drainage blanket. Vertical drains accelerate consolidation by facilitating drainage of pore water. Vertical drains are laid out in rows, staggered, or aligned to form patterns of equilateral triangles or squares. Two types of drains are discussed below
11. The vibrator first penetrates to the required depth by vibration and air or water jetting or by vibration alone.
12. Gravel is then added at the tip of the vibrator and progressive raising and repenetration of the vibrator results in the gravel being pushed into the surrounding soil.
13.
14.
15. VIBRO COMPACTION It is a ground improvement process for densifying loose sands to create stable foundation soils. The action of the vibrator, usually accompanied by water jetting, reduces the inter-granular forces between the soil particles, allowing them to move into a denser configuration, typically achieving a relative density of 70 to 85 percent. Compaction is achieved above and below the water table.
17. DYNAMIC COMPACTION Dynamic Compaction is the dropping of heavy weights on the ground surface to densify soils at depth. It involves the repeated dropping of large steel tampers by means of crawler cranes. Tampers typically range from 6 to 20 tons and are dropped from heights of about 40 to 80 feet.
19. VIBRO PIERS Vibro Piers, also known as aggregate piers, are typically installed to intermediate depths of 5 to 20 feet for the support of new loads. Vibro Piers are quick to install and very effective at reinforcing the surrounding soil. Typical Vibro Pier construction begins with pre-drilling a full-depth hole with a diameter that is equal to the final pier design diameter. For soils in which the pre-drilled hole will not stay open, the bottom feed process can be used to avoid the need for casing.
21. CONCLUSION Though the term Ground Improvement has been familiar to Civil Engineers, the design approach is still empirical, mostly based on past experience. The Importance of Ground Improvement is immeasurable. Ground stability is a vital part of any construction project. Method adopted to be applied on the field should be according to site condition and economical. Application of Ground Improvement Techniques is not only cheaper but also reduce the construction time significantly. Ground improvement technique also plays a vital role in the development of our mother land by 2020.
