Appl. No.:

5/532050

Inventors:

George G. Goble - Shaker Heights OH
Frank Rausche - Willoughby OH

International Classification:

G01N 334

US Classification:

73 84

Abstract:

A method of constructing cast-in-place concrete piles by which the static load bearing capacity of a pile is dynamically determined during its formation. In the disclosed method, successive charges of concrete are placed into a removable casing and subsequently driven into the soil by a drop hammer. The pile may be of the pedestal type having an enlarged base for increased load capacity. The pile shaft is formed by incrementally elevating the casing and driving concrete into a vertical series of annular enlargements corresponding to the points at which the lower end of the casing is stopped. The load capacity of the pile base and the individual enlargements is determined by measuring the resistance of the soil against penetration of the several concrete portions when driven by the hammer. This resistance is calculated as a product of the total mass of the concrete in motion and the hammer multiplied by the deceleration of the hammer and an adjustment factor to account for the effects of nonaxial concrete motion, energy losses, etc. , at or about the time of zero velocity as determined by a decelerometer or any other suitable device mounted on the hammer.

International Classification:

G01L 122

US Classification:

73 1B

Abstract:

A device for calibrating strain gages and strain transducers. The device includes an assembly with a first section and a second section positioned in relation to each other such that a gap is defined between the two sections. A strain transducer is attached to the assembly across the defined gap. The assembly includes an adjustment device which alters the position of the sections in relation to each other, thereby redefining the gap. A displacement sensor detects a displacement signal occurring due to the redefining of the gap caused by operation of the adjustment device. A strain transducer output detector detects a strain output signal occurring also due to the redefining of the gap by the adjustment device. A calibrating device inputs the signals from the displacement sensor and the strain transducer output detector and provides a calibration for the strain transducer attached to the assembly.

International Classification:

G01P 1509

US Classification:

73654

Abstract:

An accelerometer assembly is disclosed which includes an accelerometer mounting block formed of a rigid material having a proportion of the modulus of elasticity to the density of less than 15,000,000 psi/lb/in. sup. 3. The natural frequency of the mounting block is safely below the accelerometer's response frequency but higher than the frequency to be recorded so that the mounting block does not resonate with high frequency vibrations and cause quick saturation of the accelerometer amplifier or erratic signals. The preferred mounting block is formed of polycarbonate, which is non-metallic, rigid, and lightweight, and has a natural frequency sufficiently below that of the accelerometer.

US Classification:

702188

Abstract:

A pile driving analyzer (PDA) which obtains, processes and stores pile driving data. The PDA is operable as an independent self-contained unit, or may be used in conjunction with a remote computer system. Position data indicative of the position of a pile, and pile data indicative of characteristics of a pile may be automatically input to the PDA. When used in conjunction with the remote computer system, the PDA may be controlled remotely by the remote computer system. Alternatively, the PDA may be controlled locally by an operator, and data acquired by the PDA provided to the remote computer system for monitoring and/or storage.

Abstract:

A pile installation recording system for driven piles and auger cast piles. The recording system records a variety of parameter data received from sensing devices. The parameter data is stored, analyzed, and displayed to provide the operator with accurate and timely information regarding the pile installation. In addition, the parameter data may be stored on removable media, and further manipulated to generate a variety of reports regarding the pile installation.
