Vulcan found McKiernan-Terry to be their most formidable competitor, but there were others. One of those was the Union Iron Works, located in northern New Jersey. The catalogue for Union is here for download. An overview of the Union hammers is below. Specifications for these hammers follow. Hammers manufactured by Union Iron Works appear in … Continue reading Union Pile Driving Equipment
Today I finally finished the translation of the body of Vibro-Engineering and the Technology of Piling and Boring Work. It took long enough (it started with the translation of part of the book by Language Services in Knoxville in the early 1990's) but at last it's done. The last two chapters were done with the explicit … Continue reading My Adventure with AI: Translating the Rest of “Vibro-Engineering and the Technology of Piling and Boring Work”
For more of this book, click here. The method of deep vibro-compaction of water-saturated sandy foundations was proposed and developed by VNIIGS by P. D. Lobasov. The essence of this method is that dynamic excitation is transmitted to the water-saturated sandy mass by a spatial rod structure rigidly connected to a vibro-exciter operating at a … Continue reading Vibration Technology Of Deep Compaction Of Sandy Foundations

In non-cohesive soils, cut-off walls such as trench walls with a width of about 0.6 m, as well as thin cut-off walls with a width of 100--200 mm constructed using vibration equipment, have become widespread as anti-seepage barriers. Thin cut-off walls have advantages compared to trench walls: the … Continue reading Construction Of Thin Anti-Seepage Cut-Off Walls
For more of this book, click here. Currently, various methods are used for constructing trench walls using mainly drilling and grab equipment. One of the promising directions for increasing productivity, reducing costs and increasing the value of this work is the construction of trench walls using vibration technology. The vibration method can be successfully applied … Continue reading Application Of Vibration Technology In The Construction Of Deep Structures
For more of this book, click here. The issue of decommissioning water wells and ground-freezing wells arises in cases where these wells have fulfilled their task (drainage or ground freezing) or their operation (water supply wells) has ceased to be expedient due to a decrease in productivity that can no longer be restored. Solving the … Continue reading Casing Pipe Extraction During Well Decommissioning
For more of this book, click here. The main method for constructing wells in water depths exceeding 100–150 meters is rotary drilling with clay mud flushing of the borehole. During the development of wells drilled using the rotary method, it is necessary to remove the clay particles of the flushing fluid from the near-filter zone … Continue reading Restoring The Productivity Of Water Wells During Their Development And Repair
For more of this book, click here. If water-bearing formations consist of sands, it is advisable to install wire-wound filters with a gravel pack in the wells. This pack improves the filtration characteristics of the zone around the filter. It also increases well productivity and stabilizes its operation as a water source. One of the … Continue reading Installation Of Filter Columns When Constructing Gravel-Packed Wire-Wound Filters In Water Wells
For more of this book, click here. In the process of percussion-cable drilling, bore hole walls are reinforced with casing pipes to prevent collapse and to isolate water-bearing horizons. The low driving capacity of a drilling tool and the lack of reliable means for extracting intermediate columns when filters are exposed lead to a situation … Continue reading Immersion And Extraction Of Casing Pipes In The Process Of Percussion-Cable Drilling Of Boreholes
