Quinn Piling are able to utilise a number of different pile testing techniques. The most common areStatic Load Test Quinn Piling

Static Testing

Static testing using any of the reaction methods listed above is used to determine the relationship between load and settlement. Or to verify that the capacity of a pile exceeds the specifed load the constant rate of penetration technique is available to determine pile bearing capacity.

 

Dynamic Load Test Quinn Piling

Dynamic Testing

Dynamic load testing provides an economic alternative to conventional static load testing. The technique eliminates the requirement for expensive proof loading.

Integrity testing provides a reliable and economical method to determine pile concrete and section uniformity. The testing engineer hits the top of the pile several times with a "mallet". This then collects the data into a portable computer for analysis and reporting.

 

 

Monitoring

Quinn Piling have the capability to carryout a range of monitoring services including Inclinometer monitoring on retaining walls and vibration monitoring before, during and after piling work.

Vibration Monitoring

Vibration Monitoring by Quinn PilingQuinn Piling can install CFA piles within 1.2m of existing housing and other structures and have the ability to adapt rigs to drill within 0.5m of existing buildings and structures.

In cases where vibration is a sensitive issue due to neighbouring buildings Quinn Piling can install vibration monitors.

Monitoring can take place for the duration of the works at times specified or for longer periods outside working site hours.

The vibration monitor is equipped with an alarm. Once an agreed level of vibration is recorded (typically 5 PPV) the alarm will trigger alerting the site. Further investigations can then take place as to what is causing the levels of vibration and if it is safe to continue work.

 

 

Inclinometers

Inclinometer monitoring is to observe lateral movements within piles and asses whether remedial works are required to subdue any Inclinometer Reading by Quinn Pilingsuch movements. Quinn Pilings monitoring department has carried out inclinometer readings on some of our biggest jobs.

Pile Preparation for Inclinometers

Inclinometer casings are normally tied to the reinforcement cage at locations specified by the client. Alternatively casings can be inserted and grouted within steel ducts. The casings are fixed such that no movement of the casing from the cage can occur. It is preferable to align the casing as vertical as is practical and to align one set of grooves in the direction of any such expected movement.

After each reading Quinn Pilings monitoring department will analysis all data received and foward onto our clients.
