Demolition Hammers for Clay - Fine Homebuilding

    25.09.2002 · To dig 500' of footers in this stuff we ended up using an electric jack hammer, the spot was under a 6 story building and inaccessible to heavier equipment, with a clay spade bit that was designed for the job. The tool came in at a good 50 lbs. Set tool, hammer down to depth, pull handles to you to break the piece off, lift hammer and place in new position. Wash rinse repeat. It was a tough ...

During pile driving, when the toe response (end bearing) has a "large quake" or low stiffness, dynamic pile tension stresses in concrete piles may reach high levels that may result in damaging pile cracks, even at very high blow counts ...

    Drill Bits vs. Down-the-Hole Hammers | 2020-02 .

    Some drills require 30-inch-long anchors for drilling into clay, loamy and sandy soils. If the drill site is on rocky terrain, drillers must find alternative methods for anchoring the drills, such as placing water-filled tanks or barrels packed with rocks onto the unit. This anchoring force is crucial to pushing the DTH hammer, as well as heavy-duty drill bits, through rocky material.

    Pile Design and Construction Rules of Thumb | .

    Although many piles have been driven in clay soils using vibratory hammers, vibratory pile hammers are best suited for sandy soils. Vibratory hammers are less noisy and do not cause pile damage as compared with pile-driving hammers. One of the major problems of vibratory hammers is the unavailability of credible methods to compute the bearing capacity of piles based on penetration rates. .

    How to Estimate the Load Capacity ... - Soil .

    In the case of piles driven in clay, the soil loses some of its shear strength due to the sensitivity by remolding. As time elapses, most of the lost strength is regained by thixotropy. A time gap of minimum 30 days should be maintained from the driving of piles in clay and loading the pile. For the same reason, pile load tests in the case of driven piles in clays should be performed at least ...
