V-cut blasting, also known as V-cut drilling, is a technique used in tunnel construction for controlled rock fragmentation. This method is particularly useful in tunneling where space is confined, and precise control over the blast is needed to minimize damage to the surrounding rock and structure.  In V-cut blasting, a series of holes are drilled in a specific pattern to create a V-shape. The pattern usually consists of a central row of holes drilled at an angle (the apex of the V) and additional rows of holes on either side. The goal is to create a controlled fracture line that converges toward the center of the V. The sequence of detonation is crucial in V-cut blasting. The central holes are detonated first, creating a void that allows the surrounding rock to move and break more easily when the next set of holes is fired. The outer holes are then detonated in sequence, moving outward from the center to ensure controlled breakage and minimize overbreak.

Blast holes colar Staking/Setting out is one of the pivotal roles engineering surveyors has to play in hard excavations at a construction site. This practice helps to attain accuracy and precision in positioning of blasthole points. Below are some of the benefits which are brought by this aspect: 1. Ability to achieve the correct slope angles and levels of berms in accordance to the design specifications. 2. Avoidance of over blasting which comes with an increased cost of backfilling and slope rehabilitation. 3. Enabling effective blasting which eliminates extra costs that usually comes from secondary blasting. 4. Reduces execution time (schedule) due to availability of a drilling plan which guides the rig operater. 5. Facilitates calculation of quantities for the payment of Contractors since the survey data can be effectively used as topo data.

Nothing can stop Northeast Remsco Construction (NRC), not even boulders! Yonkers Contracting Company, Inc. hired NRC to install eight 80-foot long, 36-inch diameter pipes via microtunnel under the Light Rail in Jersey City. This project in collaboration with the Port Authority, presented unexpected challenges: horizontal probing revealed various obstructions along the casing alignment, including concrete, boulders, and cast-iron pipe. But at NRC, we don't back down. We quickly adapted by acquiring the advanced Geonex - Horizontal drilling solution (Horizontal Hammer Boring) DTH Drill Rig. This cutting-edge equipment features unique horizontal hammer technology, allowing us to penetrate even the most challenging soil conditions. The job was completed ahead of our estimated schedule.

Manually Drilled Piles?? A while back during one of my visits to a site with a senior colleague, I observed the manual drilling of bridge piles in a rather intriguing way. Traditionally, these piles were manually drilled using innovative but simple setups in contrast to modern mechanized drilling techniques. The setup was simple: A rather large hammer head with a diamond bit was lifted and released repeatedly by a pulley system powered by a diesel engine. This continuous action caused an agitations and dislodges surface particles. A lubricant compose largely of water serves a dual purpose of lubricating the drill site and transporting the dislodged particles out of the drill site While manual drilling offers certain advantages, especially in smaller projects or challenging terrains, mechanized drilling generally provides superior efficiency, precision, and cost-effectiveness, making it the preferred choice for larger and more time-sensitive bridge constructions. The choice between manually drilled bridge piles and mechanized drilling depends on the specific requirements and constraints of the project. A few advantages presented by manually drilled piles present are its cost-effectiveness for small-scale projects, low environmental Impact and flexibility in challenging terrains. while it's said advantages might be numerous there are a number of constraints that deter it's application are listed below: 1. Time-Consuming 2. Limited Depth and Diameter 3. Labor-Intensive 4. Inconsistency in Quality. what are your opinions on manual drilling of bridge piles?

▶️ what are the main advantages of using large diameter holes in pre-splitting ? Using large diameter holes in pre-splitting offers several advantages. These include reduced drilling time, cost savings on consumables, faster loading of holes, and increased stability over the long term due to wider hole spacings. Large holes allow for quicker loading with less manual handling, potentially eliminating the need for covering the holes, which saves time and effort. Additionally, the use of large-diameter holes can lead to a more stable face, especially when spaced appropriately. ▶️ what are the safety benefits of using large diameter holes in pre-splitting Using large diameter holes in pre-splitting blasting techniques can provide several safety benefits. These include: 1. Reduced risk of overbreak: Large diameter holes reduce the likelihood of overbreak, which can lead to increased rock movement and potential hazards such as rockfalls and rockslides. 2.

Tunnel Excavation Cycle - Sequence of Activities: 2) Drilling for Blast: Drilling for blast in the tunnel is a critical activity in the excavation cycle, serving as the precursor to the controlled detonation of explosives for efficient rock or soil removal. This process involves the careful and strategic drilling of holes into the tunnel face or surrounding rock, creating channels for subsequent explosive placement. The precision of these drill patterns directly influences the effectiveness of the blast and the overall excavation process. Engineers employ specialized drilling equipment and techniques, considering geological conditions and project requirements. Attention to detail in drilling ensures optimal fragmentation during blasting, facilitating safer and more efficient tunnel construction. The coordination of drilling and subsequent charging and blasting activities is essential for achieving project goals while maintaining stringent safety and environmental standards. #TunnelExcavation #BlastDrilling #PrecisionDrilling #ExplosiveExcavation #TunnelingTechnology #ExcavationCycle #EnvironmentalCompliance #BlastEngineering
