Comacchio Introduced New Lightweight Compact Piling Rig
at Conexpo 2020
The CH 300 is the smallest model of the Comacchio range of large diameter piling rigs with a transport weight of less than 65,800 lbs with rotary head and Kelly bar installed. The rig is fully self-erecting. Despite the lightweight design, the CH 300 offers a high torque output, allowing it to undertake drilling tasks that would normally require the use of larger and heavier equipment. The CH 300 can be configured both for uncased and cased bored piles up to a maximum depth of 159 ft. The rig can be easily converted to perform CFA drilling.
2 nd Generation Keystone HP Cluster Drills

Keystone Drill's 2 nd Gen HP stands just 58” tall, making it the shortest Cluster Drill in its class while maintaining industry-leading performance. Keystone's family of cluster drill products enables great potential for savings in fuel, compressor rental costs, mobilization time, bits, hammers, spare parts, etc.
Odin Construction Uses Deep Utility Excavation with Perimeter Slurry Wall for Groundwater Dewatering
Odin Construction Odin installed two 36-inch DIP utility pipes for future water storage infrastructure in constructed reservoirs adjacent to the South Platte River in Platteville, Colorado. The invert of the DIP’s was installed at 35 ft. below ground surface (bgs) and were approximately 250 ft. long. Dewatering control was attained through a value engineering design proposed by the Contractor to install a soil-bentonite slurry cutoff wall around the perimeter of the two 36 in. DIP alignments with dimensions of 365 ft. by 200 ft. The soil-bentonite slurry cutoff wall was keyed into the underlying bedrock and allowed for the DIP excavation to extend to 38 ft. bgs with minimal free water to manage with a groundwater table at 3 ft. bgs.
Pile Dynamics Introduces TIP
Technology
Thermal Integrity Profiler (TIP) utilizes heat generated by curing of concrete to assess the integrity and quality of drilled shafts, ACIP piles and other concrete foundations, inside and outside of the reinforcement cage. TIP reveals necks or inclusions, bulges, variations in concrete cover, and the shape of the shaft and cage alignment, with results available shortly after shaft installation. TIP offers wireless remote data collection in real time with PDI’s TAG (Thermal Aggregator) and TAP-Edge (Thermal Acquisition Port) boxes. TIP/TAG allows engineers, designers and contractors to see the data, via a secure Cloud server, from any location, at any time.
